Of the 21 species, between six and eight coexist inside humid lowland forests. We conducted or analyzed 31 surveys at 16 different sites, resurveying some sites in different years. The species coexisting at any single site in a single year are a highly nonrandom selection of the species to which that site is geographically accessible. Their sizes are both much more widely spread and more uniformly spaced than in random sets of species drawn from the locally available species pool. We also present a detailed case study of a highly mobile species that has been recorded on every ornithologically explored island in the West Papuan island group west of New Guinea. That species' rareness on just three well-surveyed islands within the group cannot be due to an inability to reach them. Instead, its local status decreases from abundant resident to rare vagrant in parallel with increasing weight proximity of the other resident species.}, Doi = {10.1073/pnas.2217904120}, Key = {fds369657} } @article{fds363919, Author = {Warudkar, A and Goyal, N and Kher, V and Vinay, KL and Chanda, R and Bandi, RS and Jenkins, CN and Robin, VV and Pimm, S}, Title = {Using the area of habitat to assess the extent of protection of India's birds}, Journal = {Biotropica}, Volume = {54}, Number = {6}, Pages = {1466-1479}, Year = {2022}, Month = {November}, url = {http://dx.doi.org/10.1111/btp.13132}, Abstract = {India hosts multiple global biodiversity hotspots while being one of the most populous countries in the world. Here, we examine how well India has protected its avifauna, based on the fraction of their ranges falling within “protected areas.” India has protected 5% of its land this way. The issue is whether India has done better than expected in protecting its threatened species. To this end, we assessed 99 Near Threatened, Threatened, and small-ranged species by estimating their Area of Habitat (AOH). We refined published species ranges using secondary information on elevation limits and habitat preferences. More than half (52) of the species assessed have their AOH <30% of their published ranges, while 31 have <10%. India has protected 87 threatened species' AOH more than expected (>5%), and for 33 species, the proportion protected exceeds the Aichi target (>17%). When we consider the top 10% richest regions as hotspots, only 9.2% of their total area falls under India's protected area network, inadequately covering areas with most threatened birds. We also discuss the conservation concerns for grassland and open habitat species across India, since we find that substantial proportions of their AOHs fall outside protected areas. This result highlights the significance of alternative conservation models, including other effective area-based conservation measures. We show that species' AOH provides a more realistic well-informed range that can aid in assessing their protection status.}, Doi = {10.1111/btp.13132}, Key = {fds363919} } @article{fds363010, Author = {Tinsley-Marshall, P and Downey, H and Adum, G and Al-Fulaij, N and Bourn, NAD and Brotherton, PNM and Frick, WF and Hancock, MH and Hellon, J and Hudson, MA and Kortland, K and Mastro, K and McNicol, CM and McPherson, T and Mickleburgh, S and Moss, JF and Nichols, CP and O'Brien, D and Ockendon, N and Paterson, S and Parks, D and Pimm, SL and Schofield, H and Simkins, AT and Watuwa, J and Wormald, K and Wilkinson, J and Wilson, JD and Sutherland, WJ}, Title = {Funding and delivering the routine testing of management interventions to improve conservation effectiveness}, Journal = {Journal for Nature Conservation}, Volume = {67}, Year = {2022}, Month = {June}, url = {http://dx.doi.org/10.1016/j.jnc.2022.126184}, Abstract = {Evidence-based approaches are key for underpinning effective conservation practice, but major gaps in the evidence of the effectiveness of interventions limit their use. Conservation practitioners could make major contributions to filling these gaps but often lack the time, funding, or capacity to do so properly. Many funders target the delivery of conservation and can be reluctant to fund primary research. We analysed the literature testing the effectiveness of interventions. Of a sample of 1,265 publications published in 2019 that tested conservation interventions, 96% included academics. Only 21% included conservation practitioners, of which just under half were first or last author. A community of conservation funders and practitioners undertook a series of workshops to explore means of improving the quality and quantity of intervention testing. A survey of the suggested proportion of conservation grants that should be allocated to testing intervention effectiveness showed practitioners tended to prefer larger percentages (median 3–6%) than funders (median 1–3%), but the overlap was considerable. Funders can facilitate the testing of interventions through a range of measures, including welcoming applications that incorporate testing, allocating funds to testing, and providing training and support to deliver testing. The funders represented by the authors of this paper have committed to these actions. Practitioners can contribute by committing to routine testing, benefiting from funding allocated specifically to testing, and establishing processes for testing interventions. The organisations of the practitioner authors have committed to test at least one intervention per year and share findings, regardless of outcome. Currently, practitioners rarely lead the testing of conservation actions. We suggest processes by which both funders and practitioners can make this routine. This will not only improve the effectiveness and cost-efficiency of practice, but also make conservation more attractive to funders.}, Doi = {10.1016/j.jnc.2022.126184}, Key = {fds363010} } @article{fds363339, Author = {Pimm, S}, Title = {We can have biodiversity and eat too.}, Journal = {Nature Food}, Volume = {3}, Number = {5}, Pages = {310-311}, Publisher = {Springer Science and Business Media LLC}, Year = {2022}, Month = {May}, url = {http://dx.doi.org/10.1038/s43016-022-00503-0}, Doi = {10.1038/s43016-022-00503-0}, Key = {fds363339} } @article{fds364093, Author = {Pimm, S}, Title = {Thomas Lovejoy (1941-2021).}, Journal = {Current Biology : Cb}, Volume = {32}, Number = {10}, Pages = {R446}, Year = {2022}, Month = {May}, url = {http://dx.doi.org/10.1016/j.cub.2022.03.072}, Abstract = {Stuart Pimm remembers ecologist and conservationist Tom Lovejoy, who coined the term biodiversity.}, Doi = {10.1016/j.cub.2022.03.072}, Key = {fds364093} } @article{fds362122, Author = {Bernstein, AS and Ando, AW and Loch-Temzelides, T and Vale, MM and Li, BV and Li, H and Busch, J and Chapman, CA and Kinnaird, M and Nowak, K and Castro, MC and Zambrana-Torrelio, C and Ahumada, JA and Xiao, L and Roehrdanz, P and Kaufman, L and Hannah, L and Daszak, P and Pimm, SL and Dobson, AP}, Title = {The costs and benefits of primary prevention of zoonotic pandemics.}, Journal = {Science Advances}, Volume = {8}, Number = {5}, Pages = {eabl4183}, Year = {2022}, Month = {February}, url = {http://dx.doi.org/10.1126/sciadv.abl4183}, Abstract = {The lives lost and economic costs of viral zoonotic pandemics have steadily increased over the past century. Prominent policymakers have promoted plans that argue the best ways to address future pandemic catastrophes should entail, "detecting and containing emerging zoonotic threats." In other words, we should take actions only after humans get sick. We sharply disagree. Humans have extensive contact with wildlife known to harbor vast numbers of viruses, many of which have not yet spilled into humans. We compute the annualized damages from emerging viral zoonoses. We explore three practical actions to minimize the impact of future pandemics: better surveillance of pathogen spillover and development of global databases of virus genomics and serology, better management of wildlife trade, and substantial reduction of deforestation. We find that these primary pandemic prevention actions cost less than 1/20th the value of lives lost each year to emerging viral zoonoses and have substantial cobenefits.}, Doi = {10.1126/sciadv.abl4183}, Key = {fds362122} } @article{fds362123, Author = {Dobson, A and Hopcraft, G and Mduma, S and Ogutu, JO and Fryxell, J and Anderson, TM and Archibald, S and Lehmann, C and Poole, J and Caro, T and Mulder, MB and Holt, RD and Berger, J and Rubenstein, DI and Kahumbu, P and Chidumayo, EN and Milner-Gulland, EJ and Schluter, D and Otto, S and Balmford, A and Wilcove, D and Pimm, S and Veldman, JW and Olff, H and Noss, R and Holdo, R and Beale, C and Hempson, G and Kiwango, Y and Lindenmayer, D and Bond, W and Ritchie, M and Sinclair, ARE}, Title = {Savannas are vital but overlooked carbon sinks.}, Journal = {Science (New York, N.Y.)}, Volume = {375}, Number = {6579}, Pages = {392}, Year = {2022}, Month = {January}, url = {http://dx.doi.org/10.1126/science.abn4482}, Doi = {10.1126/science.abn4482}, Key = {fds362123} } @article{fds362834, Author = {Pimm, S}, Title = {Edward O.

Here we ask what are the prospects for improving the connections between these populations? We combine 1.2 million telemetry observations from 254 elephants with spatial data on environmental factors and human land use across eight southern African countries. Telemetry data show what natural features limit elephant movement and what human factors, including fencing, further prevent or restrict dispersal. The resulting intersection of geospatial data and elephant presences provides a map of suitable landscapes that are environmentally appropriate for elephants and where humans allow elephants to occupy. We explore the environmental and anthropogenic constraints in detail using five case studies.

Here, we develop the niche-hypervolume concept of the community into a powerful model of community dynamics. We describe the community’s size through the volume of the hypercube and the dynamics of the populations in it through the fluctuations of the axes of the niche hypercube on different timescales. While the community’s size remains constant, the relative volumes of the niches within it change continuously, thus allowing the populations of different species to rise and fall in a zero-sum fashion. This dynamic hypercube model reproduces several key patterns in communities: lognormal species abundance distributions, 1/f-noise population abundance, multiscale patterns of extinction debt and logarithmic species-time curves. It also provides a powerful framework to explore significant ideas in ecology, such as the drift of ecological communities into evolutionary time.}, Doi = {10.3389/fevo.2021.686403}, Key = {fds359932} } @article{fds359852, Author = {Pimm, SL and Willigan, E and Kolarova, A and Huang, R}, Title = {Reconnecting nature.}, Journal = {Current Biology : Cb}, Volume = {31}, Number = {19}, Pages = {R1159-R1164}, Year = {2021}, Month = {October}, url = {http://dx.doi.org/10.1016/j.cub.2021.07.040}, Abstract = {The U.N. has declared 2021-2030 the 'decade of restoration' (https://www.decadeonrestoration.org). This initiative aspires to many actions, but its agenda must include 'reconnecting nature'. Even when natural habitats remain, they often come in fragments too small or isolated to sustain viable populations. Human activities surround habitats with unsuitable areas or constrict animals' movements with artificial barriers, such as roads or fences. The harm this fragmentation causes is evident. Here, we discuss various actions to mitigate its problems, seeking explicit evidence of their efficacy. These actions range from small-scale, controlled experiments to continent-wide programmes to allow species the freedom to roam. Even simple connections, such as highway overpasses or tunnels, usually allow movement such that the genetic and demographic problems that beset small, isolated populations may be diminished. Showing that species move when we give them the chance to do so may be a sufficient measure of success, even if we do not always understand the consequences in detail.}, Doi = {10.1016/j.cub.2021.07.040}, Key = {fds359852} } @article{fds358240, Author = {Kong, L and Xu, W and Xiao, Y and Pimm, SL and Shi, H and Ouyang, Z}, Title = {Spatial models of giant pandas under current and future conditions reveal extinction risks.}, Journal = {Nature Ecology and Evolution}, Volume = {5}, Number = {9}, Pages = {1309-1316}, Year = {2021}, Month = {September}, url = {http://dx.doi.org/10.1038/s41559-021-01520-1}, Abstract = {In addition to habitat loss and fragmentation, demographic processes-the vagaries of births, deaths and sex ratio fluctuations-pose substantial threats to wild giant panda populations. Additionally, climate change and plans for the Giant Panda National Park may influence (in opposing directions) the extinction risk for wild giant pandas. The Fourth National Giant Panda Census showed pandas living in 33 isolated populations. An estimated 259 animals live in 25 of these groups, ~14% of the total population. We used individual-based models to simulate time series of these small populations for 100 years. We analysed the spatial pattern of their risk of extinction under current conditions and multiple climate change models. Furthermore, we consider the impact of the proposed Giant Panda National Park. Results showed that 15 populations face a risk >90%, and for 3 other populations the risk is >50%. Of the 15 most at-risk populations, national parks can protect only 3. Under the Representative Concentration Pathway 8.5 climate change scenario, the 33 populations will probably further divide into 56 populations. Some 41 of them will face a risk >50% and 35 face a risk >90%. Although national parks will probably connect some fragmented habitats, 26 populations will be outside national park planning.

Next, we identify priority topics and offer suggestions and priorities for future biodiversity research in China. These priorities include (i) the ecology and biogeography of the Qinghai-Tibetan Plateau and surrounding mountains, and that of subtropical and tropical forests across China; (ii) marine and inland aquatic biodiversity; and (iii) effective conservation and management to identify and maintain synergies between biodiversity and socio-economic development to fulfil China's vision for becoming an ecological civilization. In addition, we propose three future strategies: (i) translate advanced biodiversity science into practice for biodiversity conservation; (ii) strengthen capacity building and application of advanced technologies, including high-throughput sequencing, genomics and remote sensing; and (iii) strengthen and expand international collaborations.

That said, we should examine what we know and, vitally, what works to conserve biodiversity and what does not. Ecosystem processes determine the fate of many species, but many attempts to theorise about ecosystems have led to ever more fanciful descriptions of nature. All conservation is local. It will only succeed if we find ways to accommodate people and nature. That does not mean indigenous knowledge acquired over millennia will be sufficient to our ever more overcrowded planet.

Given the pace of change of knowledge about species distributions and shifts in ranges under climate change and land use, a need exists for timely mapping approaches that enable batch processing employing widely available data. We develop a systematic approach of batch-processing range maps and derived Area of Habitat maps for terrestrial bird species with published ranges below 125,000 km2 in Central and South America. (Area of Habitat is the habitat available to a species within its range.) We combine existing range maps with the rapidly expanding crowd-sourced eBird data of presences and absences from frequently surveyed locations, plus readily accessible, high resolution satellite data on forest cover and elevation to map the Area of Habitat available to each species. Users can interrogate the maps produced to see details of the observations that contributed to the ranges. Previous estimates of Areas of Habitat were constrained within the published ranges and thus were, by definition, smaller-typically about 30%. This reflects how little habitat within suitable elevation ranges exists within the published ranges. Our results show that on average, Areas of Habitat are 12% larger than published ranges, reflecting the often-considerable extent that eBird records expand the known distributions of species. Interestingly, there are substantial differences between threatened and non-threatened species. Some 40% of Critically Endangered, 43% of Endangered, and 55% of Vulnerable species have Areas of Habitat larger than their published ranges, compared with 31% for Near Threatened and Least Concern species.

Media speculations about it ignore ecological realities. Worse, they make conjectures that can be detrimental to wildlife and sometimes discredit conservation incentives. A broader understanding of the ecological and conservation issues speaks to elephant management across the Kavango-Zambezi Transfrontier Conservation Area that extends across Botswana, Namibia, Angola, Zambia, and Zimbabwe. Our communication addresses these. Malicious poisoning and poaching are unlikely to have played a role. Other species were unaffected, and elephant carcases had their tusks intact. Restriction of freshwater supplies that force elephants to use pans as a water source possibly polluted by blue-green algae blooms is a possible cause, but as yet not supported by evidence. No other species were involved. A contagious disease is the more probable one. Fences and a deep channel of water confine these elephants' dispersal. These factors explain the elephants' relatively high population growth rate despite a spell of increased poaching during 2014-2018. While the deaths represent only ~2% of the area's elephants, the additive effects of poaching and stress induced by people protecting their crops cause alarm. Confinement and relatively high densities probably explain why the die-off occurred only here.

To prevent extinctions, it would be helpful to have a more comprehensive taxonomic catalogue and much greater knowledge of where plant species live. Addressing these questions must be a scientific priority. However, what we know at present is enough to effect practical conservation actions, such as protecting more land in biodiverse places, reconnecting fragmented habitats, and eliminating species introduced outside their native ranges. For the benefit of people and the planet, we can, and must act on what we know already, to prevent catastrophic plant extinctions. Summary: Continuing destruction of habitats—and especially tropical forests—the introduction of plant and herbivorous animal species outside their native ranges, and global climate disruption all contribute to the extinction of plant species. What can we do to prevent this? Do we have enough basic information to make effective conservation decisions? First, how many plant species are there? This question has an easy element—how many species we know now—and a much more difficult one—how many do we not know. Second, where are the concentrations of plant species? Third, where are the species we do not yet know? Fourth, what plant species have gone extinct, and where did they live? A related question is which species are threatened with extinction and where do they live? Fifth, how well can we map threats to species? For habitat loss, remote sensing provides satellite images globally and very frequently. It does so at a resolution that often displays individual trees and bushes. Sixth, supposing we had detailed answers to the previous questions, what are we doing to protect species? How well does the existing network of protected areas encompass species, especially those with the smallest ranges? Does that network allow for species moving upslope as the climate heats up? How well are managers doing in removing introduced species? Although answering these questions must be a scientific priority, we cannot wait until we have all the answers.

Answering these questions can focus panda conservation. We map their spatial distribution and temporal changes from 2000 to 2015, by watershed, to target future protected areas for both pandas and these ecosystem services. Pandas occupy watersheds with above-average carbon sequestration and water retention. There is no tendency for pandas to be increasing in watersheds that have higher than average values of these ecosystem services or in watersheds where they are improving. Protected areas represented watersheds with higher than average values of these ecosystem services but without pandas only poorly. Watersheds with pandas do provide higher than average ecosystem services, but watersheds above average for these ecosystem services often lack pandas.

From 1959 to 1990, forest cover remained stable, and an additional 15 species were lost-a total of 29% of the forest bird community. Thereafter, forest cover increased by 26% and 17 species recolonized the area. The main cause of extirpations was the loss of connections to adjacent forests. Of the 31 (19%) extirpated birds, 25 have ranges peripheral to San Antonio, mostly in the lowlands. Most still occurred regionally, but broken forest connections limited their recolonization. Other causes of extirpation were hunting, wildlife trade, and water diversion. Bird community changes included a shift from predominantly common species to rare species; forest generalists replaced forest specialists that require old growth, and functional groups, such as large-body frugivores and nectarivores, declined disproportionally. All water-dependent birds were extirpated. Of the remaining 122 forest species, 19 are vulnerable to climate disruption, 10 have declined in abundance, and 4 are threatened. Our results show unequivocal species losses and changes in community structure and abundance at the local scale. We found species were extirpated after habitat loss and fragmentation, but forest recovery stopped extirpations and helped species repopulate. Land-use changes increased species vulnerability to climate change, and we suggest reversing landscape transformation may restore biodiversity and improve resistance to future threats.}, Doi = {10.1111/cobi.13423}, Key = {fds347679} } @article{fds345474, Author = {Huang, R and Pimm, SL and Giri, C}, Title = {Using metapopulation theory for practical conservation of mangrove endemic birds.}, Journal = {Conservation Biology : the Journal of the Society for Conservation Biology}, Volume = {34}, Number = {1}, Pages = {266-275}, Year = {2020}, Month = {February}, url = {http://dx.doi.org/10.1111/cobi.13364}, Abstract = {As a landscape becomes increasingly fragmented through habitat loss, the individual patches become smaller and more isolated and thus less likely to sustain a local population. Metapopulation theory is appropriate for analyzing fragmented landscapes because it combines empirical landscape features with species-specific information to produce direct information on population extinction risks. This approach contrasts with descriptions of habitat fragments, which provide only indirect information on risk. Combining a spatially explicit metapopulation model with empirical data on endemic species' ranges and maps of habitat cover, we calculated the metapopulation capacity-a measure of a landscape's ability to sustain a metapopulation. Mangroves provide an ideal model landscape because they are of conservation concern and their patch boundaries are easily delineated. For 2000-20015, we calculated global metapopulation capacity for 99 metapopulations of 32 different bird species endemic to mangroves. Northern Australia and Southeast Asia had the highest richness of mangrove endemic birds. The Caribbean, Pacific coast of Central America, Madagascar, Borneo, and isolated patches in Southeast Asia in Myanmar and Malaysia had the highest metapopulation losses. Regions with the highest loss of habitat area were not necessarily those with the highest loss of metapopulation capacity. Often, it was not a matter of how much, but how the habitat was lost. Our method can be used by managers to evaluate and prioritize a landscape for metapopulation persistence.}, Doi = {10.1111/cobi.13364}, Key = {fds345474} } @article{fds366340, Author = {Pimm, SL and Raven, PH}, Title = {Norman Myers (1934-2019).}, Journal = {Nature Ecology and Evolution}, Volume = {4}, Number = {2}, Pages = {177-178}, Year = {2020}, Month = {February}, url = {http://dx.doi.org/10.1038/s41559-020-1095-8}, Doi = {10.1038/s41559-020-1095-8}, Key = {fds366340} } @article{fds344889, Author = {Brooks, TM and Pimm, SL and Akçakaya, HR and Buchanan, GM and Butchart, SHM and Foden, W and Hilton-Taylor, C and Hoffmann, M and Jenkins, CN and Joppa, L and Li, BV and Menon, V and Ocampo-Peñuela, N and Rondinini, C}, Title = {Measuring Terrestrial Area of Habitat (AOH) and Its Utility for the IUCN Red List.}, Journal = {Trends in Ecology and Evolution}, Volume = {34}, Number = {11}, Pages = {977-986}, Year = {2019}, Month = {November}, url = {http://dx.doi.org/10.1016/j.tree.2019.06.009}, Abstract = {The International Union for Conservation of Nature (IUCN) Red List of Threatened Species includes assessment of extinction risk for 98 512 species, plus documentation of their range, habitat, elevation, and other factors.

The 5% of India officially protected covers most ecoregions and protected areas have been an important reason why India has suffered no documented species extinctions in the past 70 years. India has strong legislation favouring conservation, government investment focused on 50 Tiger Reserves, and government compensation schemes that facilitate local support, all of which brighten future prospects. However, many protected areas are too small to maintain a full complement of species, making connectivity and species use of buffer zones a crucial issue. Conservation success and challenges vary across regions according to their development status. In less developed areas, notably the biodiverse northeast Himalaya, protected areas maintaining the highest biodiversity result from locally-focused efforts by dedicated individuals. Across India, we demonstrate considerable opportunities to increase local income through ecotourism. Our evaluation confirms a lack of data, increasing threats, and the importance of local support. Research on biodiversity in buffer zones, development of long-term monitoring schemes, and assessment of cash and conservation benefits from tourism are in particular need.

This net change hides considerable complexities in the types of wetlands created and destroyed. The area of open water surface increased by 9,110 km<sup>2</sup>, but natural wetlands-henceforth "marshes"-decreased by 7,562 km<sup>2</sup>. Of the expanded wetlands, restoration policies contributed 24.5% and dam construction contributed 20.8%. Climate change accounted for 23.6% but is likely to involve a transient increase due to melting glaciers. Of the lost wetlands, agricultural and urban expansion contributed 47.7% and 13.8%, respectively. The increase in wetlands from conservation efforts (6,765 km<sup>2</sup>) did not offset human-caused wetland losses (16,032 km<sup>2</sup>). The wetland changes may harm wildlife. The wetland loss in east China threatens bird migration across eastern Asia [2]. Open water from dam construction flooded the original habitats of threatened terrestrial species and affected aquatic species by fragmenting wetland habitats [3]. Thus, the "no net loss" target measures total changes without considering changes in composition and the corresponding ecological functions.

While this comprises less than 4% of the cropland in the region, it accounted for 11% of the deforestation from agricultural expansion from 2007-2013. Patches of oil palm agriculture were larger and more spatially clustered than for other crops, potentially increasing their impact on local habitat fragmentation. Modeling deforestation risk for oil palm expansion using climatic and edaphic factors showed that sites at lower elevations, with higher precipitation, and lower slopes than those typically used for intensive agriculture are at long-term risk of deforestation from oil palm agriculture. Within areas at long-term risks, based on CART models, areas near urban centers, roads, and previously deforested areas are at greatest short-term risk of deforestation. Existing protected areas and officially recognized indigenous territories cover large areas at long-term risk of deforestation for oil palm (>40%). Less than 7% of these areas are under strict (IUCN I-IV) protection. Based on these findings, we suggest targeted monitoring for oil palm deforestation as well as strengthening and expanding protected areas to conserve specific habitats.}, Doi = {10.1088/1748-9326/aae540}, Key = {fds339864} } @article{fds336962, Author = {Carter, NH and Bouley, P and Moore, S and Poulos, M and Bouyer, J and Pimm, SL}, Title = {Climate change, disease range shifts, and the future of the Africa lion.}, Journal = {Conservation Biology : the Journal of the Society for Conservation Biology}, Volume = {32}, Number = {5}, Pages = {1207-1210}, Year = {2018}, Month = {October}, url = {http://dx.doi.org/10.1111/cobi.13102}, Doi = {10.1111/cobi.13102}, Key = {fds336962} } @article{fds338072, Author = {Gagné, TO and Hyrenbach, KD and Hagemann, ME and Bass, OL and Pimm, SL and MacDonald, M and Peck, B and Van Houtan and KS}, Title = {Seabird trophic position across three ocean regions tracks ecosystem differences}, Journal = {Frontiers in Marine Science}, Volume = {5}, Number = {SEP}, Publisher = {FRONTIERS MEDIA SA}, Year = {2018}, Month = {September}, url = {http://dx.doi.org/10.3389/fmars.2018.00317}, Abstract = {We analyze recently collected feather tissues from two species of seabirds, the sooty tern (Onychoprion fuscatus) and brown noddy (Anous stolidus), in three ocean regions (North Atlantic, North Pacific, and South Pacific) with different human impacts.

For plants, 85% of species occur entirely within just over a third of the Earth's land surface, carefully optimized to maximize the species captured. Well-known vertebrate taxa show similar patterns. Protecting half of Earth might not be necessary, but would it be sufficient given the current trends of protection? The predilection of national governments is to protect areas that are "wild," that is, typically remote, cold, or arid. Unfortunately, those areas often hold relatively few species. Wild places likely afford the easier opportunities for the future expansion of protected areas, with the expansion into human-dominated landscapes the greater challenge. We identify regions that are not currently protected, but that are wild, and consider which of them hold substantial numbers of especially small-ranged vertebrate species. We assess how successful the strategy of protecting the wilder half of Earth might be in conserving biodiversity. It is far from sufficient. (Protecting large wild places for reasons other than biodiversity protection, such as carbon sequestration and other ecosystem services, might still have importance.) Unexpectedly, we also show that, despite the bias in establishing large protected areas in wild places to date, numerous small protected areas are in biodiverse places. They at least partially protect significant fractions of especially small-ranged species. So, while a preoccupation with protecting large areas for the sake of getting half of Earth might achieve little for biodiversity, there is more progress in protecting high-biodiversity areas than currently appreciated.

How do free-ranging livestock impact giant panda habitats and what are the implications for future conservation and policy on a larger scale? We use Wanglang National Nature Reserve as a case study. It has seen a nine-fold livestock increase during past 15 years. We combined bamboo survey plots, GPS collar tracking, long-term monitoring, and species distribution modelling incorporating species interaction to understand the impacts across spatial and temporal scales.

The cheetah poses challenges, but also affords unique opportunities. It is photogenic, allowing the compilation of thousands of crowd-sourced data. It is also persecuted for killing livestock, enabling estimation of local population densities from the numbers persecuted. Documented instances of persecution in areas with known human and livestock density mean that these data can provide an estimate of where the species may or may not occur in areas without observational data. Compilations of extensive telemetry data coupled with nearly 20,000 additional observations from 39 sources show that free-ranging cheetahs were present across approximately 789,700 km2 of Namibia, Botswana, South Africa, and Zimbabwe (56%, 22%, 12% and 10% respectively) from 2010 to 2016, with an estimated adult population of 3,577 animals. We identified a further 742,800 km2 of potential cheetah habitat within the study region with low human and livestock densities, where another ∼3,250 cheetahs may occur. Unlike many previous estimates, we make the data available and provide explicit information on exactly where cheetahs occur, or are unlikely to occur. We stress the value of gathering data from public sources though these data were mostly from well-visited protected areas. There is a contiguous, transboundary population of cheetah in southern Africa, known to be the largest in the world. We suggest that this population is more threatened than believed due to the concentration of about 55% of free-ranging individuals in two ecoregions. This area overlaps with commercial farmland with high persecution risk; adult cheetahs were removed at the rate of 0.3 individuals per 100 km2 per year. Our population estimate for confirmed cheetah presence areas is 11% lower than the IUCN's current assessment for the same region, lending additional support to the recent call for the up-listing of this species from vulnerable to endangered status.}, Doi = {10.7717/peerj.4096}, Key = {fds331442} } @article{fds328730, Author = {Sutton, AE and Downey, MG and Kamande, E and Munyao, F and Rinaldi, M and Taylor, AK and Pimm, S}, Title = {Boma fortification is cost-effective at reducing predation of livestock in a high-predation zone in the Western Mara Region, Kenya}, Journal = {Conservation Evidence}, Volume = {14}, Pages = {32-38}, Year = {2017}, Month = {January}, Abstract = {Lions Panthera leo kill livestock in the pastoral steppe of East Africa.

Furthermore, losses of greater than five animals per year occurred at only 17% of fortified bomas, compared to 57% of unfortified bomas. The overall reduction in losses to predation at fortified bomas equated to savings of more than &1,200 USD per household per year.}, Key = {fds328730} } @article{fds326646, Author = {Huang, RM and Bass, OL and Pimm, SL}, Title = {Sooty tern (Onychoprion fuscatus) survival, oil spills, shrimp fisheries, and hurricanes.}, Journal = {Peerj}, Volume = {5}, Pages = {e3287}, Year = {2017}, Month = {January}, url = {http://dx.doi.org/10.7717/peerj.3287}, Abstract = {Migratory seabirds face threats from climate change and a variety of anthropogenic disturbances.

Knowing how many elephants there are and how many poachers kill is important, but on their own, such data lack context. We collated savanna elephant count data from 73 protected areas across the continent estimated to hold ~50% of Africa's elephants and extracted densities from 18 broadly stable population time series. We modeled these densities using primary productivity, water availability, and an index of poaching as predictors. We then used the model to predict stable densities given current conditions and poaching for all 73 populations. Next, to generate ecological benchmarks, we predicted such densities for a scenario of zero poaching. Where historical data are available, they corroborate or exceed benchmarks. According to recent counts, collectively, the 73 savanna elephant populations are at 75% of the size predicted based on current conditions and poaching levels. However, populations are at <25% of ecological benchmarks given a scenario of zero poaching (~967,000)-a total deficit of ~730,000 elephants. Populations in 30% of the 73 protected areas were <5% of their benchmarks, and the median current density as a percentage of ecological benchmark across protected areas was just 13%.

To test the efficacy of this zoning, we employed field surveys and remote sensing to assess the penetration of agricultural and urban land into 109 national nature reserves in China for 2000 and 2010. Human disturbance was lowest in core zones and highest in experimental zones in both 2000 and 2010. Over this period, 82% of the reserves were unchanged or had decreased human disturbance. Nonetheless, overall human disturbance increased by 7%, 4%, and 5% in the core, buffer and experimental zones respectively. Almost all the increase in the core zone was in four wetland reserves, where human actions converted large areas to agriculture. Some 58% of reserves experienced some human disturbance in core zones in 2010, demonstrating a need for more effective zoning. The findings have broader implications for protected area management globally because they highlight the strengths and weaknesses of zoning for balancing human needs and species conservation.}, Doi = {10.1016/j.biocon.2016.10.028}, Key = {fds322797} } @article{fds333253, Author = {Ocampo-Peñuela, N and Jenkins, CN and Vijay, V and Li, BV and Pimm, SL}, Title = {Incorporating explicit geospatial data shows more species at risk of extinction than the current Red List.}, Journal = {Science Advances}, Volume = {2}, Number = {11}, Pages = {e1601367}, Year = {2016}, Month = {November}, url = {http://dx.doi.org/10.1126/sciadv.1601367}, Abstract = {The IUCN (International Union for Conservation of Nature) Red List classifies species according to their risk of extinction, informing global to local conservation decisions.

These data readily show that species are likely not present within many areas within the overall envelopes of their distributions. Additionally, global databases on protected areas inform how extensively ranges are protected. We selected 586 endemic and threatened forest bird species from six of the world's most biodiverse and threatened places (Atlantic Forest of Brazil, Central America, Western Andes of Colombia, Madagascar, Sumatra, and Southeast Asia). The Red List deems 18% of these species to be threatened (15 critically endangered, 29 endangered, and 64 vulnerable). Inevitably, after refining ranges by elevation and forest cover, ranges shrink. Do they do so consistently? For example, refined ranges of critically endangered species might reduce by (say) 50% but so might the ranges of endangered, vulnerable, and nonthreatened species. Critically, this is not the case. We find that 43% of species fall below the range threshold where comparable species are deemed threatened. Some 210 bird species belong in a higher-threat category than the current Red List placement, including 189 species that are currently deemed nonthreatened.

Such bodies frequently use terms pertaining to stability that lack clear definition.

Detailed data on geographical ranges are not available for plants or invertebrates, so we restrict our analyses to 3 vertebrate taxa: birds, mammals, and amphibians. There are gaps in their protection, and we recommend practical actions to fill them. We identified patterns of species richness, then identified which species are endemic to China, and then which, like the panda, live in forests. After refining each species' range by its known elevational range and remaining forest habitats as determined from remote sensing, we identified the top 5% richest areas as the centers of endemism. Southern mountains, especially the eastern Hengduan Mountains, were centers for all 3 taxa. Over 96% of the panda habitat overlapped the endemic centers. Thus, investing in almost any panda habitat will benefit many other endemics. Existing panda national nature reserves cover all but one of the endemic species that overlap with the panda's distribution. Of particular interest are 14 mammal, 20 bird, and 82 amphibian species that are inadequately protected. Most of these species the International Union for Conservation of Nature currently deems threatened. But 7 mammal, 3 bird, and 20 amphibian species are currently nonthreatened, yet their geographical ranges are <20,000 km(2) after accounting for elevational restriction and remaining habitats.

Today, consumer pressure is pushing companies toward deforestation-free sources of palm oil. To guide interventions aimed at reducing tropical deforestation due to oil palm, we analysed recent expansions and modelled likely future ones. We assessed sample areas to find where oil palm plantations have recently replaced forests in 20 countries, using a combination of high-resolution imagery from Google Earth and Landsat. We then compared these trends to countrywide trends in FAO data for oil palm planted area. Finally, we assessed which forests have high agricultural suitability for future oil palm development, which we refer to as vulnerable forests, and identified critical areas for biodiversity that oil palm expansion threatens. Our analysis reveals regional trends in deforestation associated with oil palm agriculture. In Southeast Asia, 45% of sampled oil palm plantations came from areas that were forests in 1989. For South America, the percentage was 31%. By contrast, in Mesoamerica and Africa, we observed only 2% and 7% of oil palm plantations coming from areas that were forest in 1989.

Secondly, we ask: do our results suggest species of concern-those at considerably greater risk than hitherto appreciated? Thirdly, these assessments are not only important on a species-by-species basis. By combining distributions of species of concern, we map conservation priorities. We ask to what degree these areas are currently protected and how might knowledge from remote sensing modify the priorities?

There are many studies on the projected loss of habitats as climate warms, but few consider the geographical arrangement of future habitats, current protected area, and species' dispersal abilities.

A 35% reduction will occur in future effectiveness of reserve networks. The results challenge the long-term effectiveness of protected areas in protecting the species' persistence.

To adequately protect the nation's unique biodiversity, we recommend specific areas deserving additional protection, some of them including public lands, but many others requiring private investment.}, Doi = {10.1073/pnas.1418034112}, Key = {fds279090} } @article{fds279097, Author = {De Vos and JM and Joppa, LN and Gittleman, JL and Stephens, PR and Pimm, SL}, Title = {Estimating the normal background rate of species extinction.}, Journal = {Conservation Biology : the Journal of the Society for Conservation Biology}, Volume = {29}, Number = {2}, Pages = {452-462}, Year = {2015}, Month = {April}, ISSN = {0888-8892}, url = {http://dx.doi.org/10.1111/cobi.12380}, Abstract = {A key measure of humanity's global impact is by how much it has increased species extinction rates. Familiar statements are that these are 100-1000 times pre-human or background extinction levels. Estimating recent rates is straightforward, but establishing a background rate for comparison is not. Previous researchers chose an approximate benchmark of 1 extinction per million species per year (E/MSY). We explored disparate lines of evidence that suggest a substantially lower estimate. Fossil data yield direct estimates of extinction rates, but they are temporally coarse, mostly limited to marine hard-bodied taxa, and generally involve genera not species. Based on these data, typical background loss is 0.01 genera per million genera per year. Molecular phylogenies are available for more taxa and ecosystems, but it is debated whether they can be used to estimate separately speciation and extinction rates. We selected data to address known concerns and used them to determine median extinction estimates from statistical distributions of probable values for terrestrial plants and animals. We then created simulations to explore effects of violating model assumptions. Finally, we compiled estimates of diversification-the difference between speciation and extinction rates for different taxa. Median estimates of extinction rates ranged from 0.023 to 0.135 E/MSY. Simulation results suggested over- and under-estimation of extinction from individual phylogenies partially canceled each other out when large sets of phylogenies were analyzed. There was no evidence for recent and widespread pre-human overall declines in diversity. This implies that average extinction rates are less than average diversification rates. Median diversification rates were 0.05-0.2 new species per million species per year. On the basis of these results, we concluded that typical rates of background extinction may be closer to 0.1 E/MSY. Thus, current extinction rates are 1,000 times higher than natural background rates of extinction and future rates are likely to be 10,000 times higher.}, Doi = {10.1111/cobi.12380}, Key = {fds279097} } @article{fds279092, Author = {Pimm, SL and Joppa, LN}, Title = {How many plant species are there, where are they, and at what rate are they going extinct?}, Journal = {Annals of the Missouri Botanical Garden}, Volume = {100}, Number = {3}, Pages = {170-176}, Publisher = {Missouri Botanical Garden Press}, Year = {2015}, Month = {March}, ISSN = {0026-6493}, url = {http://dx.doi.org/10.3417/2012018}, Abstract = {How many flowering plant species are there?

They are important in themselves and directly determine the diversity of many other taxonomic groups. Inspired by conversations with Peter Raven, we set out to provide quantitative answers to these questions.

We will only get a good answer to the age-old question of "how many species are there?" when we understand the population biology and social behavior of taxonomists. That most missing species will be found in biodiversity hotspots reaffirms their place as the foci of extinction for decades to come. Important, but not yet addressed, are future studies of how long plant species take to become extinct in habitat fragments.

Most conservation efforts target biodiversity hotspots at large scales. Such approach overlooks small-sized local hotspots, which may be rich in endemic and highly threatened species. We explore the importance of mountain rock pools (gueltas) as local biodiversity hotspots in the Sahara-Sahel. Specifically, we considered how many vertebrates (total and endemics) use gueltas, what factors predict species richness, and which gueltas are of most priority for conservation. We expected to provide management recommendations, improve local biodiversity conservation, and simultaneously contribute with a framework for future enhancement of local communities' economy. The identification of local hotspots of biodiversity is important for revaluating global conservation priorities.<h4>Methodology/principal findings</h4>We quantified the number of vertebrate species from each taxonomic group and endemics present in 69 gueltas in Mauritania, then compared these with species present in a surrounding area and recorded in the country. We evaluated the predictors of species number's present in each guelta through a multiple regression model. We ranked gueltas by their priority for conservation taking into account the percentage of endemics and threats to each guelta. Within a mere aggregate extent of 43 ha, gueltas hold about 32% and 78% of the total taxa analysed and endemics of Mauritania, respectively. The number of species present in each guelta increased with the primary productivity and area of gueltas and occurrence of permanent water. Droughts and human activities threaten gueltas, while 64% of them are currently unprotected.<h4>Conclusion/significance</h4>Gueltas are crucial for local biodiversity conservation and human activities. They require urgent management plans in Mauritania's mountains. They could provide refugia under climate change being important for long-term conservation of Sahara-Sahel biodiversity. Given their disproportional importance in relation to their size, they are local hotspots of biodiversity deserving global attention.}, Doi = {10.1371/journal.pone.0118367}, Key = {fds279093} } @article{fds279095, Author = {Ocampo-Peñuela, N and Pimm, SL}, Title = {Bird conservation would complement landslide prevention in the Central Andes of Colombia.}, Journal = {Peerj}, Volume = {3}, Pages = {e779}, Year = {2015}, Month = {January}, url = {http://dx.doi.org/10.7717/peerj.779}, Abstract = {Conservation and restoration priorities often focus on separate ecosystem problems.

This area is one of the most biodiverse places on Earth, but also one of the most threatened. Using the case of the Rio Blanco Reserve, near Manizales, we identified areas for conservation where endemic and small-range bird diversity was high, and where landslide risk was also high. We further prioritized restoration areas by overlapping these conservation priorities with a forest cover map. Restoring forests in bare areas of high landslide risk and important bird diversity yields benefits for both biodiversity and people. We developed a simple landslide susceptibility model using slope, forest cover, aspect, and stream proximity. Using publicly available bird range maps, refined by elevation, we mapped concentrations of endemic and small-range bird species. We identified 1.54 km(2) of potential restoration areas in the Rio Blanco Reserve, and 886 km(2) in the Central Andes region.

Tropical montane birds face these threats with the added natural vulnerability of narrower elevational ranges and higher specialization than lowland species. Recent studies assess the impact of present and future global climate change on species' ranges, but only a few of these evaluate the potentially confounding effect of lowland deforestation on species elevational distributions. In the Western Andes of Colombia, an important biodiversity hotspot, we evaluated the effects of deforestation on the elevational ranges of montane birds along altitudinal transects. Using point counts and mist-nets, we surveyed six altitudinal transects spanning 2200 to 2800 m. Three transects were forested from 2200 to 2800 m, and three were partially deforested with forest cover only above 2400 m. We compared abundance-weighted mean elevation, minimum elevation, and elevational range width. In addition to analysing the effect of deforestation on 134 species, we tested its impact within trophic guilds and habitat preference groups. Abundance-weighted mean and minimum elevations were not significantly different between forested and partially deforested transects. Range width was marginally different: as expected, ranges were larger in forested transects. Species in different trophic guilds and habitat preference categories showed different trends. These results suggest that deforestation may affect species' elevational ranges, even within the forest that remains. Climate change will likely exacerbate harmful impacts of deforestation on species' elevational distributions. Future conservation strategies need to account for this by protecting connected forest tracts across a wide range of elevations.}, Doi = {10.1371/journal.pone.0143311}, Key = {fds322809} } @article{fds279087, Author = {Si, X and Pimm, SL and Russell, GJ and Ding, P}, Title = {Turnover of breeding bird communities on islands in an inundated lake}, Journal = {Journal of Biogeography}, Volume = {41}, Number = {12}, Pages = {2283-2292}, Year = {2014}, Month = {December}, ISSN = {0305-0270}, url = {http://dx.doi.org/10.1111/jbi.12379}, Abstract = {Aim: MacArthur and Wilson's theory of island biogeography proposes that the rate at which species colonize an island depends on the island's isolation (distance effect), whereas the local extinction rate depends on its area (area effect). Alternative hypotheses recognize that area can affect the colonization rate (target effect) and that isolation can affect the extinction rate (rescue effect) and, moreover, that these relationships may dominate. We quantify these relationships and associated turnover rates and incidence using long-term counts of breeding bird communities on islands in an inundated lake. Location: Thousand Island Lake, China. Methods: We assessed the occupancy and behaviour of breeding birds on 37 islands from 2007 to 2012. We estimated the effects of area, isolation and other biogeographical parameters on the frequencies of colonization and extinction events using multivariate logistic regression. We then extended these results to derived properties such as species turnover rates and incidence. Results: Extinction rates decreased and colonization rates increased on larger islands. Isolation had no significant effect on colonization or extinction rates. Islands had high species turnover overall, and turnover rates followed the same pattern as extinction rates with different areas and isolations. Pool turnover, which controls for the number of species in the pool, was higher on large islands. Species richness also increased with area. Our study of bird communities supported area and target effects, but not distance and rescue effects. Main conclusions: Island area was a better predictor of colonization and extinction than isolation, probably because of the relatively small scale (c. 580km2) and homogeneous vegetation structure of our research system, and the strong dispersal ability of birds. We conclude that the differences between our observations and theoretical predictions, or results from other studies that measured colonization and extinction directly, are consistent with the particular biogeography of these islands.}, Doi = {10.1111/jbi.12379}, Key = {fds279087} } @article{fds279100, Author = {Ocampo-Peñuela, N and Pimm, SL}, Title = {Setting practical conservation priorities for birds in the Western Andes of Colombia.}, Journal = {Conservation Biology : the Journal of the Society for Conservation Biology}, Volume = {28}, Number = {5}, Pages = {1260-1270}, Year = {2014}, Month = {October}, ISSN = {0888-8892}, url = {http://dx.doi.org/10.1111/cobi.12312}, Abstract = {We aspired to set conservation priorities in ways that lead to direct conservation actions. Very large-scale strategic mapping leads to familiar conservation priorities exemplified by biodiversity hotspots. In contrast, tactical conservation actions unfold on much smaller geographical extents and they need to reflect the habitat loss and fragmentation that have sharply restricted where species now live. Our aspirations for direct, practical actions were demanding. First, we identified the global, strategic conservation priorities and then downscaled to practical local actions within the selected priorities. In doing this, we recognized the limitations of incomplete information. We started such a process in Colombia and used the results presented here to implement reforestation of degraded land to prevent the isolation of a large area of cloud forest. We used existing range maps of 171 bird species to identify priority conservation areas that would conserve the greatest number of species at risk in Colombia. By at risk species, we mean those that are endemic and have small ranges. The Western Andes had the highest concentrations of such species-100 in total-but the lowest densities of national parks. We then adjusted the priorities for this region by refining these species ranges by selecting only areas of suitable elevation and remaining habitat. The estimated ranges of these species shrank by 18-100% after accounting for habitat and suitable elevation. Setting conservation priorities on the basis of currently available range maps excluded priority areas in the Western Andes and, by extension, likely elsewhere and for other taxa. By incorporating detailed maps of remaining natural habitats, we made practical recommendations for conservation actions. One recommendation was to restore forest connections to a patch of cloud forest about to become isolated from the main Andes.}, Doi = {10.1111/cobi.12312}, Key = {fds279100} } @article{fds279101, Author = {Pimm, SL and Jenkins, CN and Abell, R and Brooks, TM and Gittleman, JL and Joppa, LN and Raven, PH and Roberts, CM and Sexton, JO}, Title = {The biodiversity of species and their rates of extinction, distribution, and protection.}, Journal = {Science (New York, N.Y.)}, Volume = {344}, Number = {6187}, Pages = {1246752}, Year = {2014}, Month = {May}, ISSN = {0036-8075}, url = {http://dx.doi.org/10.1126/science.1246752}, Abstract = {Recent studies clarify where the most vulnerable species live, where and how humanity changes the planet, and how this drives extinctions.

Models that predict preferences combine location data from tracked animals with environmental information, usually at a spatial resolution determined by the available data. This resolution may be biologically irrelevant for the species in question. Individuals likely integrate environmental characteristics over varying distances when evaluating their surroundings; we call this the scale of selection. Even a single characteristic might be viewed differently at different scales; for example, a preference for sheltering under trees does not necessarily imply a fondness for continuous forest. Multi-scale preference is likely to be particularly evident for animals that occupy coarsely heterogeneous landscapes like savannahs. We designed a method to identify scales at which species respond to resources and used these scales to build preference models. We represented different scales of selection by locally averaging, or smoothing, the environmental data using kernels of increasing radii. First, we examined each environmental variable separately across a spectrum of selection scales and found peaks of fit. These 'candidate' scales then determined the environmental data layers entering a multivariable conditional logistic model. We used model selection via AIC to determine the important predictors out of this set. We demonstrate this method using savannah elephants (Loxodonta africana) inhabiting two parks in southern Africa. The multi-scale models were more parsimonious than models using environmental data at only the source resolution. Maps describing habitat preferences also improved when multiple scales were included, as elephants were more often in places predicted to have high neighborhood quality. We conclude that elephants select habitat based on environmental qualities at multiple scales. For them, and likely many other species, biologists should include multiple scales in models of habitat selection.

This fine scale is a significant methodological improvement, because it brings mapping to scales comparable with regional decisions on where to place protected areas. We also mapped recent species discoveries, because they suggest where as-yet-unknown species might be living. To assess the protection of the priority areas, we calculated the percentage of priority areas within protected areas using the latest data from the World Database of Protected Areas, providing a snapshot of how well the planet's protected area system encompasses vertebrate biodiversity. Although the priority areas do have more protection than the global average, the level of protection still is insufficient given the importance of these areas for preventing vertebrate extinctions.

Although mapping fragmentation from satellite imagery is easy, efficient techniques for relating maps of remaining habitat to extinction risk are few. Purely spatial metrics from landscape ecology are hard to interpret and do not address extinction directly. Spatially explicit metapopulation models link fragmentation to extinction risk, but standard models work only at small scales. Counterintuitively, these models predict that a species in a large, contiguous habitat will fare worse than one in 2 tiny patches. This occurs because although the species in the large, contiguous habitat has a low probability of extinction, recolonization cannot occur if there are no other patches to provide colonists for a rescue effect. For 4 ecologically comparable bird species of the North Central American highland forests, we devised metapopulation models with area-weighted self-colonization terms; this reflected repopulation of a patch from a remnant of individuals that survived an adverse event. Use of this term gives extra weight to a patch in its own rescue effect. Species assigned least risk status were comparable in long-term extinction risk with those ranked as threatened.

The metric links detailed spatial information on fragment sizes and spatial configuration to the birds' abilities to occupy and disperse across large areas (100,000+ km(2)). In the Atlantic Forest, metapopulation capacities were largely bimodal, in that most species' ranges had either low capacity (high risk of extinction) or high capacity (very small risk of extinction). This pattern persisted within taxonomically and ecologically homogenous groups, indicating that it is driven by fragmentation patterns and not differences in species ecology. Worryingly, we found IUCN considers some 28 of 58 species in the low metapopulation capacity cluster to not be threatened. We propose that assessing the effect of fragmentation will separate species more clearly into distinct risk categories than does a simple assessment of remaining habitat.}, Doi = {10.1371/journal.pone.0065357}, Key = {schnell2013quantitative} } @article{riggio2013size, Author = {Riggio, J and Jacobson, A and Dollar, L and Bauer, H and Becker, M and Dickman, A and Funston, P and Groom, R and Henschel, P and de Iongh, H and Lichtenfeld, L and Pimm, S}, Title = {The size of savannah Africa: A lion's (Panthera leo) view}, Journal = {Biodiversity and Conservation}, Volume = {22}, Number = {1}, Pages = {17-35}, Publisher = {Springer Nature}, Year = {2013}, Month = {January}, ISSN = {0960-3115}, url = {http://dx.doi.org/10.1007/s10531-012-0381-4}, Abstract = {We define African savannahs as being those areas that receive between 300 and 1,500 mm of rain annually. This broad definition encompasses a variety of habitats. Thus defined, savannahs comprise 13.5 million km2 and encompass most of the present range of the African lion (Panthera leo). Dense human populations and extensive conversion of land to human use preclude use by lions. Using high-resolution satellite imagery and human population density data we define lion areas, places that likely have resident lion populations. In 1960, 11.9 million km2 of these savannahs had fewer than 25 people per km2. The comparable area shrank to 9.7 million km2 by 2000. Areas of savannah Africa with few people have shrunk considerably in the last 50 years and human population projections suggest they will likely shrink significantly in the next 40. The current extent of free-ranging lion populations is 3.4 million km2 or about 25 % of savannah area. Habitats across this area are fragmented; all available data indicate that between 32,000 and 35,000 free-ranging lions live in 67 lion areas. Although these numbers are similar to previous estimates, they are geographically more comprehensive. There is abundant evidence of widespread declines and local extinctions. Under the criteria we outline, ten lion areas qualify as lion strongholds: four in East Africa and six in Southern Africa. Approximately 24,000 lions are in strongholds, with an additional 4,000 in potential ones. However, over 6,000 lions are in populations of doubtful long-term viability. Lion populations in West and Central Africa are acutely threatened with many recent, local extinctions even in nominally protected areas. © 2012 The Author(s).}, Doi = {10.1007/s10531-012-0381-4}, Key = {riggio2013size} } @article{badiou2013conserving, Author = {Badiou, Pascal and Baldwin, Robert and Carlson, Matt and Darveau, Marcel and Drapeau, Pierre and Gaston, Kevin and Jacobs, John and Kerr, Jeremy and Levin, Simon and Manseau, Micheline and others}, Title = {Conserving the World’s Last Great Forest Is Possible: Here’s How}, Year = {2013}, Key = {badiou2013conserving} } @misc{pimm2013tracks, Author = {Pimm, Stuart}, Title = {Tracks and Shadows: Field Biology as Art}, Publisher = {NATURE PUBLISHING GROUP MACMILLAN BUILDING, 4 CRINAN ST, LONDON N1 9XW, ENGLAND}, Year = {2013}, Key = {pimm2013tracks} } @article{katz2013summer, Author = {Katz, David and Bell, Jim and Mulder, Monique Borgerhoff and Mody, Cyrus CM and Nicholls, Henry and Harman, Oren and Davis, Mike and Alonzo, Suzanne and Pimm, Stuart and Juma, Calestous and others}, Title = {Summer books}, Journal = {Nature}, Volume = {499}, Number = {7457}, Pages = {150--153}, Publisher = {Nature Publishing Group}, Year = {2013}, Key = {katz2013summer} } @article{badiou2013preservation, Author = {Badiou, Pascal and Baldwin, Robert and Carlson, Matt and Darveau, Marcel and Drapeau, Pierre and Gaston, Kevin and Jacobs, John and Kerr, Jeremy and Levin, Simon and Manseau, Micheline and others}, Title = {Pr{\'e}servation de la derni{\`e}re grande for{\^e}t de la Terre: mode d’emploi}, Year = {2013}, Key = {badiou2013preservation} } @article{pimm2013careers, Author = {Pimm, Stuart}, Title = {Careers: A guide to the life scientific}, Journal = {Nature}, Volume = {496}, Number = {7445}, Pages = {297--297}, Publisher = {Nature Publishing Group}, Year = {2013}, Key = {pimm2013careers} } @article{pimm2013book, Author = {Pimm, Stuart}, Title = {The Book of Barely Imagined Beings: A 21st Century Bestiary}, Journal = {Nature}, Volume = {499}, Number = {7457}, Pages = {152--152}, Publisher = {Macmillan Publishers Ltd., London, England}, Year = {2013}, Key = {pimm2013book} } @article{fds279130, Author = {Scheffers, BR and Joppa, LN and Pimm, SL and Laurance, WF}, Title = {Erratum to: "What we know and don't know about Earth's missing biodiversity".

We discuss our long-term approach to the problem and the resulting successful conservation actions and, in doing so provide a possible guide for others trying to focus their conservation efforts. Through a progressive series of intuitive GIS analyses, we showed that the Atlantic Forest has the highest concentration of threatened birds in the Americas. Within the Atlantic Forest, the state of Rio de Janeiro has the highest concentration of those threatened birds. Within Rio de Janeiro state, an isolated lowland forest fragment of a few thousand hectares stands out as the highest priority for preventing bird extinctions. We identified the creation of a small forest corridor to that fragment as the most effective action we could take to prevent bird extinctions, in all of the Americas. Today, we know that corridor as the Fazenda Dourada and the trees are growing back. That success was the result of a specific research and conservation agenda, one that is long-term, based on quantitative science, and guided by local conservation actors. © 2011 ABECO.}, Doi = {10.4322/natcon.2011.021}, Key = {jenkins2011conservation} } @article{fds358241, Author = {Grehan, JR and Schwartz, JH}, Title = {Evolution of human-ape relationships remains open for investigation}, Journal = {Journal of Biogeography}, Volume = {38}, Number = {12}, Pages = {2397-2404}, Publisher = {WILEY}, Year = {2011}, Month = {December}, url = {http://dx.doi.org/10.1111/j.1365-2699.2011.02577.x}, Doi = {10.1111/j.1365-2699.2011.02577.x}, Key = {fds358241} } @article{joppa2011population, Author = {Joppa, LN and Roberts, DL and Pimm, SL}, Title = {The population ecology and social behaviour of taxonomists.}, Journal = {Trends in Ecology and Evolution}, Volume = {26}, Number = {11}, Pages = {551-553}, Year = {2011}, Month = {November}, url = {http://www.ncbi.nlm.nih.gov/pubmed/21862170}, Doi = {10.1016/j.tree.2011.07.010}, Key = {joppa2011population} } @article{joppa2011biodiversity, Author = {Joppa, LN and Roberts, DL and Myers, N and Pimm, SL}, Title = {Biodiversity hotspots house most undiscovered plant species.}, Journal = {Proceedings of the National Academy of Sciences of the United States of America}, Volume = {108}, Number = {32}, Pages = {13171-13176}, Publisher = {National Acad Sciences}, Year = {2011}, Month = {August}, url = {http://www.ncbi.nlm.nih.gov/pubmed/21730155}, Abstract = {For most organisms, the number of described species considerably underestimates how many exist.

Shifts in geographic ranges are common responses in temperate regions. For the tropics, latitudinal temperature gradients are shallow; the only escape for species may be to move to higher elevations. There are few data to suggest that they do. Yet, the greatest loss of species from climate disruption may be for tropical montane species.<h4>Methodology/principal findings</h4>We repeat a historical transect in Peru and find an average upward shift of 49 m for 55 bird species over a 41 year interval. This shift is significantly upward, but also significantly smaller than the 152 m one expects from warming in the region. To estimate the expected shift in elevation we first determined the magnitude of warming in the locality from historical data. Then we used the temperature lapse rate to infer the required shift in altitude to compensate for warming. The range shifts in elevation were similar across different trophic guilds.<h4>Conclusions</h4>Endothermy may provide birds with some flexibility to temperature changes and allow them to move less than expected. Instead of being directly dependent on temperature, birds may be responding to gradual changes in the nature of the habitat or availability of food resources, and presence of competitors.

Over the past 32. years, Amazonian forest fragments ranging from 1 to 100. ha have experienced a wide array of ecological changes. Edge effects have been a dominant driver of fragment dynamics, strongly affecting forest microclimate, tree mortality, carbon storage, fauna, and other aspects of fragment ecology. However, edge-effect intensity varies markedly in space and time, and is influenced by factors such as edge age, the number of nearby edges, and the adjoining matrix of modified vegetation surrounding fragments. In our study area, the matrix has changed markedly over the course of the study (evolving from large cattle pastures to mosaics of abandoned pasture and regrowth forest) and this in turn has strongly influenced fragment dynamics and faunal persistence. Rare weather events, especially windstorms and droughts, have further altered fragment ecology. In general, populations and communities of species in fragments are hyperdynamic relative to nearby intact forest. Some edge and fragment-isolation effects have declined with a partial recovery of secondary forests around fragments, but other changes, such as altered patterns of tree recruitment, are ongoing. Fragments are highly sensitive to external vicissitudes, and even small changes in local land-management practices may drive fragmented ecosystems in markedly different directions. The effects of fragmentation are likely to interact synergistically with other anthropogenic threats such as logging, hunting, and especially fire, creating an even greater peril for the Amazonian biota. © 2010.}, Doi = {10.1016/j.biocon.2010.09.021}, Key = {fds279238} } @article{forero2011constraints, Author = {FORERO-MEDINA, G. and Joppa, L. and Pimm, S.L.}, Title = {Constraints to species’ elevational range shifts as climate changes}, Journal = {Conservation Biology}, Volume = {25}, Number = {1}, Pages = {163--171}, Publisher = {Wiley Online Library}, Year = {2011}, Key = {forero2011constraints} } @article{joppa2011many, Author = {Joppa, L.N. and Roberts, D.L. and Pimm, S.L.}, Title = {How many species of flowering plants are there?}, Journal = {Proceedings of the Royal Society B: Biological Sciences}, Volume = {278}, Number = {1705}, Pages = {554}, Publisher = {The Royal Society}, Year = {2011}, Key = {joppa2011many} } @article{laurance2011fate, Author = {Laurance, W.F. and Camargo, J.L.C. and Luiz{\~a}o, R.C.C. and Laurance, S.G. and Pimm, S.L. and Bruna, E.M. and Stouffer, P.C. and Bruce Williamson and G. and Ben{\'\i}tez-Malvido, J. and Vasconcelos, H.L. and others}, Title = {The fate of Amazonian forest fragments: A 32-year investigation}, Journal = {Biological Conservation}, Volume = {144}, Number = {1}, Pages = {56--67}, Publisher = {Elsevier}, Year = {2011}, Key = {laurance2011fate} } @article{fds202890, Author = {Brooks, T.

Even in relatively well-known groups, there may be substantial numbers of such species. It seems likely that these unknown species will be rare and threatened with extinction. Indeed, science may not discover them before they go extinct. We address these issues for a sample of endemic flowering plants and three vertebrate groups: amphibians, birds, and mammals, all from Brazil. We predict the likely numbers of missing species from models of the declining numbers of species described per five-year interval. The raw numbers increase over time, so we must scale these by the taxonomic effort. We show that while the catalogues of birds and mammals are nearly complete, the numbers of amphibians may increase by 15% and the numbers of endemic plants by ~10 to ~50% depending on region. These percentages may still seem encouragingly low, given the complexities of studying a country as large as Brazil, with its extraordinary diversity, and with many of its regions large and still poorly explored. What is more worrying is that these numbers of as-yet unknown species are broadly the same as the percentages of species that are presently considered threatened with extinction. That is, we know only half of the species in danger of extinction - and our knowledge of even those species has mostly been acquired in the last three decades. © 2010 ABECO.}, Doi = {10.4322/natcon.00801011}, Key = {ISI:000281649700012} } @article{ISI:000279682600007, Author = {Shrader, AM and Pimm, SL and van Aarde, RJ}, Title = {Elephant survival, rainfall and the confounding effects of water provision and fences}, Journal = {Biodiversity and Conservation}, Volume = {19}, Number = {8}, Pages = {2235-2245}, Publisher = {Springer Nature}, Year = {2010}, Month = {July}, ISSN = {0960-3115}, url = {http://dx.doi.org/10.1007/s10531-010-9836-7}, Abstract = {Elephant are increasing across some areas of Africa leading to concerns that they may reduce woodlands through their feeding. Droughts may help limit elephant numbers, but they are generally both episodic and local. To explore more general impacts of rainfall, we examine how its annual variation influences elephant survival across ten sites. These sites span an almost coast-to-coast transect of southern Africa that holds the majority of the ~500,000 remaining savanna elephants. Elephants born in high rainfall years survive better than elephants born in low rainfall years. The relationship is generally weak, except at the two fenced sites, where rainfall greatly influenced juvenile survival. In these two sites, there are also extensive networks of artificial water. Rainfall likely affects elephant survival through its influence on food. The provision of artificial water opens new areas for elephants in the dry season, while fencing restricts their movements in the wet season. We conclude that the combination of these factors makes elephant survival more susceptible to reductions in rainfall. As a result, elephants living in enclosed reserves may be the first populations to feel the impacts of global warming which will decrease average rainfall and increase the frequency of droughts. A way to prevent these elephants from damaging the vegetation within these enclosed parks is for managers to reduce artificial water sources or, whenever practical, to remove fences. © 2010 Springer Science+Business Media B.V.}, Doi = {10.1007/s10531-010-9836-7}, Key = {ISI:000279682600007} } @article{ISI:000276425400021, Author = {Jenkins, CN and Alves, MAS and Pimm, SL}, Title = {Avian conservation priorities in a top-ranked biodiversity hotspot}, Journal = {Biological Conservation}, Volume = {143}, Number = {4}, Pages = {992-998}, Publisher = {Elsevier BV}, Year = {2010}, Month = {April}, ISSN = {0006-3207}, url = {http://dx.doi.org/10.1016/j.biocon.2010.01.014}, Abstract = {Rio de Janeiro state in Brazil has one of the most diverse and most endangered avifaunas in the continental Americas. Many of these endangered birds are endemic to the Atlantic Forest biodiversity hotspot, and some even endemic to Rio de Janeiro itself. As with all other forested hotspots, little original forest remains. Much of that is outside formal protected areas and faces the risk of deforestation. These factors create special circumstances for setting conservation priorities - ones common to hotspots in general - but typically not to many conservation priority setting exercises. We mapped the distribution of the remaining habitat for the 189 birds in Rio de Janeiro state that are officially endangered and/or endemic to the Atlantic Forest. Using those habitat maps, we calculated the amount of habitat currently within protected areas for each species. We then prioritized all non-protected parts of the state for their avian conservation value and their potential contribution to a comprehensive protected area system. This analysis identified 10% of the remaining unprotected part of the state as the highest priority for avian conservation. We further highlight specific locations where conservation actions could create a more comprehensive protected area system for the avifauna of Rio de Janeiro state. © 2010 Elsevier Ltd.

In particular, are these networks nested - a pattern where resources taken by more specialized consumers form a proper subset of those taken by more generalized consumers? Organisms: Fifty-nine and 42 networks of mutualistic and host-parasitoid interactions, respectively. Analytical methods: For each network, the observed degree of nestedness is compared with the distribution of nestedness values derived from a collection of 1000 random networks. Those networks with nestedness values lower than 95% of all random values are considered 'unusually nested'. The analysis considers two different metrics of nestedness and five different network randomization algorithms, each of which differs in the ecological assumptions imposed. Results: Most ecological networks are unusually nested when compared with loosely constrained random networks. Comparisons with highly constrained networks temper these findings, but we still report a significant preponderance of nested networks (typically those with the most species). Conclusions: Bascompte et al. (2003) previously showed most observed mutualistic networks to be unusually nested. Later work using more ecologically realistic randomization algorithms cast doubt on those results. Across the largest set of species interactions considered to date, we conclude that an unexpectedly large number of interaction networks are patterned in a non-random manner. © 2010 Stuart L.

Understanding elephant vegetation preferences across relevant spatial and temporal scales is a critical step towards managing protected areas for the persistence of both elephants and biodiversity. To better understand elephant vegetation selection, we fitted 68 elephants with GPS collars across a strong rainfall gradient spanning seven southern African countries over a period of 6 years. We compared elephant locations with remotely-sensed environmental data that measure bi-monthly vegetation greenness across the study area. Elephants consistently seek out greener than expected vegetation throughout the year. Interestingly, they do so by utilizing vegetation with different phenologies and by selecting landscapes when they are greener than their surroundings. We found no differences between dry and wet savannas. These patterns persist even when elephants are constrained by seasonally available water. In the wet season, elephants select seasonally variable landscapes such as open woodlands, shrublands, and grasslands. These landscapes have a lower average annual greenness but become very green for a few months in the wet season. In the dry season, elephants prefer less variable landscapes that are more consistently green year-round such as well-wooded areas and closed woodlands. Because elephants prefer different vegetation types at different times of the year, small homogeneous protected areas may be unsuitable for elephants. Since elephants prefer woody vegetation during the dry season when they are constrained by water, human actions that increase dry season water availability may contribute to detrimental elephant impacts on vegetation and biodiversity. © 2009 Elsevier Ltd.

This seeming paradox stems from how quickly human persecution can eliminate elephants across large areas and how quickly elephant numbers can increase when protected. Much elephant research concentrates on the extent and consequences of elephant persecution. Where elephants thrive, two other human interventions, the provision of artificial water and the construction of fences may have large, and perhaps unintended, impacts on elephant behavior. In general, successful management requires that we understand elephant movements and land-use choices across large areas and long periods. Here, we ask specifically how artificial water and fences might affect these movements. To do this, we first characterize how elephants move in different seasons and landscape types, in different years, and how these patterns change over a region that varies considerably in annual rainfall. We fitted 73 elephants with GPS collars across a large rainfall gradient spanning seven southern African countries over a period of 6 years. We analyzed remotely-sensed environmental data from four satellite borne sensors that measure daily rainfall, weekly temperature, bi-monthly greenness, and summarise human infrastructure. Elephants move approximately 6 km/day in dry landscapes, down to approximately 3 km/day in the wettest ones. Strong seasonal differences modulate geographic differences. Elephants move less, cover less area, and are more faithful to landscapes across years in the dry season than the wet. Water availability drives these seasonal patterns. Seasonal differences in the area covered are less pronounced in wet landscapes where permanent water is more dispersed. Within-day movements reveal that elephants are consistently crepuscular but more active at night than midday when temperatures are high. Direction-changes are centered at midnight when elephants are close to water indicating regular nighttime treks to water. By design, our analyses seek to find general patterns of elephant movements - something that one can achieve only across a large range of locations and ecological conditions - in order to understand the impact of human interventions. We show that both interventions reduce seasonal differences in elephant ranging patterns and increase local impacts of elephants on the vegetation. Artificial water sources allow more extensive dry season ranging, allowing elephants to use - and potentially overexploit - vegetation in areas that would have be otherwise inaccessible to them except in the wet season. Fences cause elephants to "bunch-up" against them during the wet season, again locally increasing the pressure elephants put on their resources. © 2009 Elsevier Ltd.

Location We evaluate these hypotheses using a detailed dataset on the occurrence and abundance of terrestrial birds on nine islands off the coast of Britain and the Republic of Ireland. Methods Unlike previous studies, we compile data on species that visit the islands, rather than just those that breed on them. We divided the species into five mutually exclusive categories based upon their migratory status and where they regularly breed: British residents, summer visitors to Britain, winter visitors to Britain, and vagrants from Europe or beyond Europe. For each species group on each island we calculated the average number of species visiting each year. We then regressed the average number of species against island area and distance to the mainland (all variables were log-transformed). We also compared the average number of species visiting each island with the average number of species breeding on each island. Results Average number of visiting British residents decreased significantly with increasing island distance, but showed no relationship with island area. There was no significant relationship between island area or island distance and average number of summer or winter visitors. European and non-European vagrants likewise showed no relationship between numbers of species visiting and island distance. However, the relationship between island area and number of visiting species was significant for both these categories; as island area increases so too does the number of visiting species. Main conclusions As predicted by IBT, there were fewer visiting species on more distant islands. There were substantially more visitors to each island than breeding species, supporting Lack's argument that lower bird richness is not a result of varying immigration rates (as predicted by IBT) but rather a result of some other island property, e.g. fewer resources. Birds make a decision to either leave an island or stay and breed. The target effect was also clearly demonstrated by the increase in European and non-European breeders with increasing island size. © 2009 Blackwell Publishing Ltd.}, Doi = {10.1111/j.1365-2699.2009.02090.x}, Key = {ISI:000268056000010} } @article{pimm2009climate, Author = {Pimm, SL}, Title = {Climate disruption and biodiversity.}, Journal = {Current Biology : Cb}, Volume = {19}, Number = {14}, Pages = {R595-R601}, Publisher = {Elsevier}, Year = {2009}, Month = {July}, url = {http://www.ncbi.nlm.nih.gov/pubmed/19640498}, Abstract = {'Global warming' may be a familiar term, but it is seriously misleading. Human actions are causing a massive disruption to the planet's climate that is severe, rapid, very variable over space and time, and highly complex. The biosphere itself is complex and its responses to even simple changes are difficult to predict in detail. One can likely only be certain that many changes will be unexpected and some unfortunate. Even the simple, slow warming of the climate will produce complex consequences to species numbers and distributions because of how species depend on each other. An alternative approach to worrying about details is to concentrate on understanding the most significant ecological changes, ones that are irreversible--so-called 'tipping points'. Once such a point has been passed, even if society managed to restore historical climatic conditions, it might not restore the historical ecological patterns. Nowhere is this more obvious than in the loss of species, for we cannot recreate them.

In particular, will one find 'checkerboards' - a pattern of mutual exclusivity that is the simplest pattern that might occur under competitive exclusion? Organisms: 150 and 141 species of land birds inhabiting 41 and 142 islands of the Bismarck and the Solomon Archipelagos, respectively. (See http://evolutionary-ecology.com/data/ 2447-Supplement.pdf) Analytical methods: For each pair of species within each archipelago, the observed number of co-occurrences is compared to the distribution of the number of co-occurrences derived from a collection of 106 representative unique random, or null, communities. Those species pairs actually co-occurring less often than they do in 5% of those nulls are 'unusually negative' pairs; those co-occurring more often than they do in 95% of those nulls are 'unusually positive' pairs. Islands are ranked from those with the smallest number of species to the largest. A species incidence is the span from the smallest to the largest number of species on islands on which it is found. Results: In each archipelago, proportionately more congeneric species pairs than non-congeneric species pairs are unusually negative pairs. This holds even for species pairs that overlap in their incidences. Among congeneric species pairs found in both archipelagos, a pair that is unusual in one archipelago generally proves to be unusual in the other archipelago as well and to belong to a genus segregating ecologically by means of spatial niche differences. Conclusions: Diamond (1975) suggested that island bird communities were structured by assembly rules that could be deduced by observation of which species did or did not co-occur on particular islands. Critics countered with analyses arguing that co-occurrence patterns in several ecological communities did not differ from random expectations. We conclude that the difference between chance and pattern can be unequivocally determined. © 2009 Stuart L.

Accurate estimates of survival are critical to improve management decisions and population estimates for this and other threatened species. We used Program MARK to evaluate effects of age, sex, population membership, temporal variation, and ground-water levels on annual survival from markrecapture data collected across 3 sparrow populations from 1997 to 2007. We found little evidence that annual survival rates differed between the populations or across ground-water levels, but we found high variability between years for both adult and juvenile survival. Our results revealed female sparrows experienced 1419 lower survival than males. Sparrows experienced much lower survival during their first year of life and were short-lived (23 yr). Our results highlight sparrows' susceptibility to population declines and suggest that management actions aimed at increasing survival may be effective for this species' management.}, Doi = {10.2193/2007-467}, Key = {ISI:000266133900009} } @article{joppa2009population, Author = {Joppa, LN and Loarie, SR and Pimm, SL}, Title = {On population growth near protected areas.}, Journal = {Plos One}, Volume = {4}, Number = {1}, Pages = {e4279}, Publisher = {Public Library of Science}, Year = {2009}, Month = {January}, url = {http://www.ncbi.nlm.nih.gov/pubmed/19169358}, Abstract = {<h4>Background</h4>Protected areas are the first, and often only, line of defense in efforts to conserve biodiversity. They might be detrimental or beneficial to rural communities depending on how they alter economic opportunities and access to natural resources. As such, protected areas may attract or repel human settlement. Disproportionate increases in population growth near protected area boundaries may threaten their ability to conserve biodiversity.<h4>Methodology/principal findings</h4>Using decadal population datasets, we analyze population growth across 45 countries and 304 protected areas. We find no evidence for population growth near protected areas to be greater than growth of rural areas in the same country. Furthermore, we argue that what growth does occur near protected areas likely results from a general expansion of nearby population centers.<h4>Conclusions/significance</h4>Our results contradict those from a recent study by Wittemyer et al., who claim overwhelming evidence for increased human population growth near protected areas. To understand the disagreement, we re-analyzed the protected areas in Wittemyer et al.'s paper. Their results are simply artifacts of mixing two incompatible datasets. Protected areas may experience unusual population pressures near their edges; indeed, individual case studies provide examples.

In the Amazon, fires are closely linked to deforestation, and thus can be used as a proxy for reserve effectiveness in protecting forest cover. We ask whether reserves in the Brazilian Amazon provide effective protection against deforestation and consequently fires, whether that protection is because of their location or their legal status, and whether some reserve types are more effective than others.<h4>Methodology/principal findings</h4>Previous work has shown that most Amazonian fires occur close to roads and are more frequent in El Niño years. We quantified these relationships for reserves and unprotected areas by examining satellite-detected hot pixels regressed against road distance across the entire Brazilian Amazon and for a decade with 2 El Niño-related droughts. Deforestation fires, as measured by hot pixels, declined exponentially with increasing distance from roads in all areas. Fewer deforestation fires occurred within protected areas than outside and the difference between protected and unprotected areas was greatest near roads. Thus, reserves were especially effective at preventing these fires where they are known to be most likely to burn; but they did not provide absolute protection. Even within reserves, at a given distance from roads, there were more deforestation fires in regions with high human impact than in those with low impact. The effect of El Niño on deforestation fires was greatest outside of reserves and near roads. Indigenous reserves, limited-use reserves, and fully protected reserves all had fewer fires than outside areas and did not appear to differ in their effectiveness.<h4>Conclusions/significance</h4>Taking time, regional factors, and climate into account, our results show that reserves are an effective tool for curbing destructive burning in the Amazon.}, Doi = {10.1371/journal.pone.0005014}, Key = {adeney2009reserves} } @article{van2009achieving, Author = {Van Houtan and K.S. and Halley, J.M. and Van Aarde and R. and Pimm, S.L.}, Title = {Achieving success with small, translocated mammal populations}, Journal = {Conservation Letters}, Volume = {2}, Number = {6}, Pages = {254--262}, Publisher = {Wiley Online Library}, Year = {2009}, Key = {van2009achieving} } @article{pimm2009boreal, Author = {Pimm, S. and Roulet, N. and Weaver, A.}, Title = {Boreal forests' carbon stores need better management}, Journal = {Nature}, Volume = {462}, Number = {7271}, Pages = {276--276}, Publisher = {Nature Publishing Group}, Year = {2009}, Key = {pimm2009boreal} } @article{loarie2009elephant, Author = {Loarie, S.R. and van Aarde, R.J. and Pimm, S.L.}, Title = {Elephant seasonal vegetation preferences across dry and wet savannas}, Journal = {Biological Conservation}, Volume = {142}, Number = {12}, Pages = {3099--3107}, Publisher = {Elsevier}, Year = {2009}, Key = {loarie2009elephant} } @article{joppa2009reciprocal, Author = {Joppa, L.N. and Bascompte, J. and Montoya, J.M. and Sole, R.V. and Sanderson, J. and Pimm, S.L.}, Title = {Reciprocal specialization in ecological networks}, Journal = {Ecology letters}, Volume = {12}, Number = {9}, Pages = {961--969}, Publisher = {Wiley Online Library}, Year = {2009}, Key = {joppa2009reciprocal} } @article{loarie2009fences, Author = {Loarie, S.R. and Aarde, R.J.V. and Pimm, S.L.}, Title = {Fences and artificial water affect African savannah elephant movement patterns}, Journal = {Biological conservation}, Volume = {142}, Number = {12}, Pages = {3086--3098}, Publisher = {Elsevier}, Year = {2009}, Key = {loarie2009fences} } @article{sanderson2009pairwise, Author = {Sanderson, J.G. and Diamond, J.M. and Pimm, S.L.}, Title = {Pairwise co-existence of Bismarck and Solomon landbird species}, Journal = {Evolutionary Ecology Research}, Volume = {11}, Number = {5}, Pages = {771--786}, Year = {2009}, Key = {sanderson2009pairwise} } @article{stracey2009testing, Author = {Stracey, C.M. and Pimm, S.L.}, Title = {Testing island biogeography theory with visitation rates of birds to British islands}, Journal = {Journal of biogeography}, Volume = {36}, Number = {8}, Pages = {1532--1539}, Publisher = {Wiley Online Library}, Year = {2009}, Key = {stracey2009testing} } @article{boulton2009endangered, Author = {Boulton, R.L. and Lockwood, J.L. and Davis, M.J. and Pedziwilk, A. and Boadway, K.A. and Boadway, J.J.T. and Okines, D. and Pimm, S.L.}, Title = {Endangered Cape Sable seaside sparrow survival}, Journal = {The Journal of Wildlife Management}, Volume = {73}, Number = {4}, Pages = {530--537}, Publisher = {Wiley Online Library}, Year = {2009}, Key = {boulton2009endangered} } @article{pimm2009we, Author = {Pimm, S}, Title = {How we got to be top dog}, Journal = {Update}, Volume = {24}, Number = {3}, Year = {2009}, Key = {pimm2009we} } @article{alves2009birds, Author = {Alves, MAS and Jenkins, CN and Pimm, SL and Storni, A and Raposo, MA and Brooke, ML and Harris, G and Foster, A}, Title = {Birds, Montane forest, State of Rio de Janeiro, Southeastern Brazil}, Journal = {Check List}, Volume = {5}, Number = {2}, Pages = {289-299}, Year = {2009}, Key = {alves2009birds} } @article{ISI:000268530200018, Author = {Pimm Stuart and L}, Title = {Climate Disruption and Biodiversity}, Journal = {Current Biology : Cb}, Volume = {19}, Number = {14, Sp.

Human actions are causing a massive disruption to the planet's climate that is severe, rapid, very variable over space and time, and highly complex. The biosphere itself is complex and its responses to even simple changes are difficult to predict in detail. One can likely only be certain that many changes will be unexpected and some unfortunate. Even the simple, slow warming of the climate will produce complex consequences to species numbers and distributions because of how species depend on each other. An alternative approach to worrying about details is to concentrate on understanding the most significant ecological changes, ones that are irreversible - so-called `tipping points'. Once such a point has been passed, even if society managed to restore historical climatic conditions, it might not restore the historical ecological patterns. Nowhere is this more obvious than in the loss of species, for we cannot recreate them. Climate disruptions may cause the loss of a large fraction of the planet's biodiversity, even if the only mechanism were to be species ranges moving uphill as temperatures rise.}, Key = {ISI:000268530200018} } @article{ISI:000260810100022, Author = {Alves, MAS and Pimm, SL and Storni, A and Raposo, MA and Brooke, MDL and Harris, G and Foster, A and Jenkins, CN}, Title = {Mapping and exploring the distribution of the Vulnerable grey-winged cotinga Tijuca condita}, Journal = {Oryx}, Volume = {42}, Number = {4}, Pages = {562-566}, Publisher = {Cambridge University Press (CUP)}, Year = {2008}, Month = {October}, ISSN = {0030-6053}, url = {http://dx.doi.org/10.1017/S0030605308001014}, Abstract = {The grey-winged cotinga Tijuca condita was first described in 1980 from an old specimen, misidentified as a congener.

Accurately defining the locations this species inhabits is an obvious prerequisite for designing conservation strategies to protect it. Using remotely sensed data on elevation and forest cover we mapped this species' habitat and predicted six more sites where it may occur. Field surveys confirmed two of them, doubling the known range of the species. The two easternmost predicted sites did not contain the species but these areas have less annual rainfall than other sites, which may explain the absences.

Unlike the eastern Brazilian Amazon, it is still a largely intact ecosystem. Underlying this landscape are large reserves of oil and gas, many yet untapped. The growing global demand is leading to unprecedented exploration and development in the region.<h4>Methodology/principal findings</h4>We synthesized information from government sources to quantify the status of oil development in the western Amazon. National governments delimit specific geographic areas or "blocks" that are zoned for hydrocarbon activities, which they may lease to state and multinational energy companies for exploration and production. About 180 oil and gas blocks now cover approximately 688,000 km(2) of the western Amazon. These blocks overlap the most species-rich part of the Amazon. We also found that many of the blocks overlap indigenous territories, both titled lands and areas utilized by peoples in voluntary isolation. In Ecuador and Peru, oil and gas blocks now cover more than two-thirds of the Amazon. In Bolivia and western Brazil, major exploration activities are set to increase rapidly.<h4>Conclusions/significance</h4>Without improved policies, the increasing scope and magnitude of planned extraction means that environmental and social impacts are likely to intensify.

Human actions destroy between 1 and 2 million km(2) of such forests per decade, with concomitant carbon release into the atmosphere. Within these forests, protected areas are the principle defense against forest loss and species extinctions. Four regions-the Amazon, Congo, South American Atlantic Coast, and West Africa-once constituted about half the world's tropical moist forest. We measure forest cover at progressively larger distances inside and outside of protected areas within these four regions, using datasets on protected areas and land-cover. We find important geographical differences. In the Amazon and Congo, protected areas are generally large and retain high levels of forest cover, as do their surroundings. These areas are protected de facto by being inaccessible and will likely remain protected if they continue to be so. Deciding whether they are also protected de jure-that is, whether effective laws also protect them-is statistically difficult, for there are few controls. In contrast, protected areas in the Atlantic Coast forest and West Africa show sharp boundaries in forest cover at their edges. This effective protection of forest cover is partially offset by their very small size: little area is deep inside protected area boundaries. Lands outside protected areas in the Atlantic Coast forest are unusually fragmented. Finally, we ask whether global databases on protected areas are biased toward highly protected areas and ignore "paper parks."

Knowing how small a species' range has to be before authorities consider it threatened with extinction would allow prediction of a species' risk from continued deforestation and warming climates and provide a baseline for conservation and management strategies aspiring to mitigate these threats. To determine the threshold at which forest-dependent bird species become threatened with extinction, we compared the range sizes of threatened and nonthreatened species. In doing so, we present a simple, repeatable, and practical protocol to quantify range size. We started with species' ranges published in field guides or comparable sources. We then trimmed these ranges, that is, we included only those parts of the ranges that met the species' requirements of elevation and types of forest preferred. Finally, we further trimmed the ranges to the amount of forest cover that remains. This protocol generated an estimate of the remaining suitable range for each species. We compared these range estimates with those from the World Conservation Union Red List. We used the smaller of the two estimates to determine the threshold, 11,000 km2, below which birds should be considered threatened. Species considered threatened that have larger ranges than this qualified under other (nonspatial) red list criteria. We identified a suite of species (18) that have not yet qualified as threatened but that have perilously small ranges--about 11% of the nonthreatened birds we analyzed.

If so, they should anticipate higher impacts to neighbouring vegetation. © 2008 Fauna and Flora International.}, Doi = {10.1017/S0030605308000483}, Key = {fds279408} } @article{vale2008effects, Author = {VALE, M.M. and COHN-HAFT, M. and Bergen, S. and PIMM, S.L.}, Title = {Effects of future infrastructure development on threat status and occurrence of Amazonian birds}, Journal = {Conservation Biology}, Volume = {22}, Number = {4}, Pages = {1006--1015}, Publisher = {Wiley Online Library}, Year = {2008}, Key = {vale2008effects} } @article{pimm2008imagine, Author = {Pimm, S.L.}, Title = {Imagine immortal elephants}, Journal = {Oryx}, Volume = {42}, Number = {01}, Pages = {2--2}, Publisher = {Cambridge Univ Press}, Year = {2008}, Key = {pimm2008imagine} } @article{alves2008mapping, Author = {Alves, M.A.S. and Pimm, S.L. and Storni, A. and Raposo, M.A. and Brooke, M.L. and Harris, G. and Foster, A. and Jenkins, C.N.}, Title = {Mapping and exploring the distribution of the Vulnerable grey-winged cotinga Tijuca condita}, Journal = {Oryx}, Volume = {42}, Number = {4}, Pages = {562--566}, Publisher = {Cambridge Univ Press}, Year = {2008}, Key = {alves2008mapping} } @article{harris2008rules, Author = {Harris, G.M. and Russell, G.J. and Van Aarde and R.I. and Pimm, S.L.}, Title = {Rules of habitat use by elephants Loxodonta africana in southern Africa: insights for regional management}, Journal = {Oryx}, Volume = {42}, Number = {01}, Pages = {66--75}, Publisher = {Cambridge Univ Press}, Year = {2008}, Key = {harris2008rules} } @article{finer2008oil, Author = {Finer, M. and Jenkins, C.N. and Pimm, S.L. and Keane, B. and Ross, C.}, Title = {Oil and gas projects in the western Amazon: Threats to wilderness, biodiversity, and indigenous peoples}, Journal = {PLoS One}, Volume = {3}, Number = {8}, Pages = {e2932}, Publisher = {Public Library of Science}, Year = {2008}, Key = {finer2008oil} } @article{harris2008range, Author = {Harris, G. and PIMM, S.L.}, Title = {Range size and extinction risk in forest birds}, Journal = {Conservation Biology}, Volume = {22}, Number = {1}, Pages = {163--171}, Publisher = {Wiley Online Library}, Year = {2008}, Key = {harris2008range} } @article{pimm2008biodiversity, Author = {Pimm, S.L.}, Title = {Biodiversity: Climate Change or Habitat Loss—Which Will Kill More Species?}, Journal = {Current Biology}, Volume = {18}, Number = {3}, Pages = {R117--R119}, Publisher = {Elsevier}, Year = {2008}, Key = {pimm2008biodiversity} } @article{joppa2008protection, Author = {Joppa, L.N. and Loarie, S.R. and Pimm, S.L.}, Title = {On the protection of “protected areas”}, Journal = {Proceedings of the National Academy of Sciences}, Volume = {105}, Number = {18}, Pages = {6673}, Publisher = {National Acad Sciences}, Year = {2008}, Key = {joppa2008protection} } @article{vale2008biopiracy, Author = {Vale, M.M. and Alves, M.A. and Pimm, S.L.}, Title = {Biopiracy: conservationists have to rebuild lost trust}, Journal = {Nature}, Volume = {453}, Number = {7191}, Pages = {26--26}, Publisher = {Nature Publishing Group}, Year = {2008}, Key = {vale2008biopiracy} } @article{pimm2008wild, Author = {Pimm, S}, Title = {Where the Wild Things Were: Life, Death and Ecological Wreckage of Vanishing Predators by William Stolzenburg}, Journal = {Nature London}, Volume = {454}, Number = {7202}, Pages = {275}, Publisher = {NATURE PUBLISHING GROUP}, Year = {2008}, Key = {pimm2008wild} } @article{pimm2008missing, Author = {Pimm, S}, Title = {Missing links in food-chain story}, Journal = {Nature}, Volume = {454}, Number = {7202}, Pages = {275-276}, Publisher = {NATURE PUBLISHING GROUP}, Year = {2008}, Key = {pimm2008missing} } @article{ISI:000257665300017, Author = {Pimm Stuart}, Title = {Where the wild things were: life, death and ecological wreckage of vanishing predators}, Journal = {Nature}, Volume = {454}, Number = {7202}, Pages = {275-276}, Year = {2008}, ISSN = {0028-0836}, Key = {ISI:000257665300017} } @article{fds279401, Author = {Harris, G and Pimm, SL}, Title = {Range size and extinction risk in forest birds.}, Journal = {Conservation Biology}, Volume = {21}, Pages = {567-569}, Year = {2008}, Key = {fds279401} } @article{fds279402, Author = {Alves, and S, MA and Pimm, SL and Storni, A and Raposo, MA and Brooke, MDL and Harris, G and Foster, A and Jenkins, CN}, Title = {Mapping and exploring the distribution of a threatened bird, Grey-winged Cotinga}, Journal = {Oryx}, Volume = {42}, Pages = {562-566}, Year = {2008}, Key = {fds279402} } @article{ISI:000255841600030, Author = {Joppa, Lucas N. and Loarie, Scott R. and Pimm, Stuart L.}, Title = {On the protection of ``protected areas{''}}, Journal = {PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA}, Volume = {105}, Number = {18}, Pages = {6673-6678}, Year = {2008}, ISSN = {0027-8424}, Abstract = {Tropical moist forests contain the majority of terrestrial species. Human actions destroy between 1 and 2 million km(2) of such forests per decade, with concomitant carbon release into the atmosphere. Within these forests, protected areas are the principle defense against forest loss and species extinctions. Four regions-the Amazon, Congo, South American Atlantic Coast, and West Africa-once constituted about half the world's tropical moist forest. We measure forest cover at progressively larger distances inside and outside of protected areas within these four regions, using data-sets on protected areas and land-cover. We find important geographical differences. In the Amazon and Congo, protected areas are generally large and retain high levels of forest cover, as do their surroundings. These areas are protected de facto by being inaccessible and will likely remain protected if they continue to be so. Deciding whether they are also protected de jure - that is, whether effective laws also protect them-is statistically difficult, for there are few controls. In contrast, protected areas in the Atlantic Coast forest and West Africa show sharp boundaries in forest cover at their edges. This effective protection of forest cover is partially offset by their very small size: little area is deep inside protected area boundaries. Lands outside protected areas in the Atlantic Coast forest are unusually fragmented. Finally, we ask whether global databases on protected areas are biased toward highly protected areas and ignore ``paper parks.{''} Analysis of a Brazilian database does not support this presumption.}, Key = {ISI:000255841600030} } @article{ISI:000255398800017, Author = {Vale, Mariana M. and Alves, Maria Alice and Pimm, Stuart L.}, Title = {Biopiracy: conservationists have to rebuild lost trust}, Journal = {NATURE}, Volume = {453}, Number = {7191}, Pages = {26}, Year = {2008}, ISSN = {0028-0836}, Key = {ISI:000255398800017} } @article{ISI:000253233800014, Author = {Pimm, Stuart L.}, Title = {Biodiversity: Climate change or habitat loss - Which will kill more species?}, Journal = {CURRENT BIOLOGY}, Volume = {18}, Number = {3}, Pages = {R117-R119}, Year = {2008}, ISSN = {0960-9822}, Abstract = {Habitat loss and climate change both kill off species.

The IUCN Red List of Threatened Species lists both as Vulnerable but they have been removed from Brazil's list of threatened species because of data deficiency. They are poorly known, reflecting both Roraima state's distance from Brazil's main population centres and the inaccessibility of their habitat. In 2004 and 2005, we conducted bird surveys along the major rivers that provided previous sightings, and expanded records from only a handful to several dozens. We found C. carbonaria at 29% of the points surveyed, and estimated its local population density at approximately 80 individuals km-2 and total population size to exceed 15,000 individuals. The species has 723 km2 of available habitat, 8% of which is inside conservation units. We found S. kollari at 44% of the points surveyed, and estimated its local population density as approximately 60 individuals km2, with an estimated total population size exceeding 5,000 individuals. It has 206 km2 of available habitat, none of which is inside conservation units. We recommend that C. carbonaria be down-listed on the IUCN Red List to the Near Threatened category, and that S. kollari be listed as Endangered. Both species live in areas vulnerable to habitat loss. We also recommend that both species re-enter the Brazilian list of threatened species and highlight the importance of indigenous reserves to their conservation. © 2007 Birdlife International.}, Doi = {10.1017/S0959270907000743}, Key = {ISI:000250430300006} } @article{ISI:000247934500022, Author = {Pimm, SL}, Title = {Imagine a better world}, Journal = {Nature}, Volume = {448}, Number = {7150}, Pages = {135-136}, Publisher = {Springer Science and Business Media LLC}, Year = {2007}, Month = {July}, ISSN = {0028-0836}, url = {http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000247934500022&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=47d3190e77e5a3a53558812f597b0b92}, Doi = {10.1038/448135a}, Key = {ISI:000247934500022} } @article{ISI:000246843200001, Author = {Pimm, SL}, Title = {Africa: still the "dark continent".}, Journal = {Conservation Biology : the Journal of the Society for Conservation Biology}, Volume = {21}, Number = {3}, Pages = {567-569}, Year = {2007}, Month = {June}, ISSN = {0888-8892}, url = {http://www.ncbi.nlm.nih.gov/pubmed/17531033}, Doi = {10.1111/j.1523-1739.2007.00697.x}, Key = {ISI:000246843200001} } @article{ISI:000244227800007, Author = {Van Houtan and KS and Pimm, SL and Halley, JM and Bierregaard, RO and Lovejoy, TE}, Title = {Dispersal of Amazonian birds in continuous and fragmented forest.}, Journal = {Ecology Letters}, Volume = {10}, Number = {3}, Pages = {219-229}, Year = {2007}, Month = {March}, ISSN = {1461-023X}, url = {http://www.ncbi.nlm.nih.gov/pubmed/17305805}, Abstract = {Many ecologists believe birds disappear from tropical forest fragments because they are poor dispersers.

We found that species which disappear from fragments move extensively between plots before isolation, but not after, and often disperse to longer distances in continuous forest than in fragmented forest. Such species also preferentially emigrate from smaller to larger fragments, showing no preference in continuous forest. In contrast, species that persist in fragments are generally less mobile, do not cross gaps as often, yet disperse further after fragmentation than before.

We also placed temperature data loggers in each of the landscapes, to obtain corresponding ambient temperatures for each hour. Our results suggest that elephants may select landscapes based on the rate at which temperatures changed and also for shade. We suggest that these selected variables provide a thermal benefit to individuals.

This is higher than the benchmark rate of approximately 1 E/MSY before human impacts, but is a serious underestimate. First, Polynesian expansion across the Pacific also exterminated many species well before European explorations. Second, three factors increase the rate: (i) The number of known extinctions before 1800 is increasing as taxonomists describe new species from skeletal remains. (ii) One should calculate extinction rates over the years since taxonomists described the species. Most bird species were described only after 1850. (iii) Some species are probably extinct; there is reluctance to declare them so prematurely. Thus corrected, recent extinction rates are approximately 100 E/MSY. In the last decades, the rate is <50 E/MSY, but would be 150 E/MSY were it not for conservation efforts. Increasing numbers of extinctions are on continents, whereas previously most were on islands. We predict a 21st century rate of approximately 1,000 E/MSY. Extinction threatens 12% of bird species; another 12% have small geographical ranges and live where human actions rapidly destroy their habitats. If present forest losses continue, extinction rates will reach 1,500 E/MSY by the century's end. Invasive species, expanding human technologies, and global change will harm additional species. Birds are poor models for predicting extinction rates for other taxa. Human actions threaten higher fractions of other well known taxa than they do birds.

Once part of a continuous, widespread population, panthers became isolated in south Florida more than a century ago. Numbers declined and the occurrence of genetic defects increased. Hoping to reverse the genetic damage, managers introduced eight female panthers from Texas into south Florida in the mid-1990s. This action was highly controversial and we explain the arguments for and against the intervention. We synthesized data systematically collected on the Florida panthers from before, during and after this management intervention. These data include information on movements, breeding, mortality, survivorship and range. There is no evidence that purebred Florida females produce fewer kittens at a later age or less often than do hybrid cats (i.e. those with a Texas ancestor). Hybrid kittens have about a three times higher chance of becoming adults as do purebred ones. Hybrid adult females survive better than purebred females; there is no obvious difference between the males. Males die younger than females, are more often killed by other males and are more likely to disperse longer distances into habitats that are dangerous to them. Hybrids are expanding the known range of habitats panthers occupy and use. © 2006 The Zoological Society of London.}, Doi = {10.1111/j.1469-1795.2005.00010.x}, Key = {ISI:000236766400002} } @article{ISI:000236384700002, Author = {Russell, GJ and Diamond, JM and Reed, TM and Pimm, SL}, Title = {Breeding birds on small islands: island biogeography or optimal foraging?}, Journal = {The Journal of Animal Ecology}, Volume = {75}, Number = {2}, Pages = {324-339}, Year = {2006}, Month = {March}, ISSN = {0021-8790}, url = {http://www.ncbi.nlm.nih.gov/pubmed/16637986}, Abstract = {1. We test MacArthur and Wilson's theory about the biogeography of communities on isolated habitat patches using bird breeding records from 16 small islands off the coasts of Britain and Ireland. 2. A traditional examination of patterns of species richness on these islands suggests that area and habitat diversity are important predictors, but that isolation and latitude have a negligible impact in this system. 3. Unlike traditional studies, we directly examine the fundamental processes of colonization and local extinction (cessation of breeding), rather than higher-order phenomena such as species richness. 4. We find that many of MacArthur and Wilson's predictions hold: colonization probability is lower on more isolated islands, and extinction probability is lower on larger islands and those with a greater diversity of habitats. 5. We also find an unexpected pattern: extinction probability is much lower on more isolated islands. This is the strongest relationship in these data, and isolation is the best single predictor of colonization and extinction. 6. Our results show that examination of species richness alone is misleading. Isolation has a strong effect on both of the dynamic processes that underlie richness, and in this system, the reductions in both colonization and extinction probability seen on more distant islands have opposing influences on species richness, and largely cancel each other out. 7. We suggest that an appropriate model for this system might be optimal foraging theory, which predicts that organisms will stay longer in a resource patch if the distance to a neighbouring patch is large. If nest sites and food are the resources in this system, then optimal foraging theory predicts the pattern we observe. 8. We advance the hypothesis that there is a class of spatial systems, defined by their scale and by the taxon under consideration, at which decision-making processes are a key driver of the spatiotemporal dynamics. The appropriate theory for such systems will be a hybrid of concepts from biogeography/metapopulation theory and behavioural ecology.}, Doi = {10.1111/j.1365-2656.2006.01052.x}, Key = {ISI:000236384700002} } @article{ISI:000235123100010, Author = {Van Houtan and KS and Pimm, SL and Bierregaard, RO and Lovejoy, TE and Stouffer, PC}, Title = {Local extinctions in flocking birds in Amazonian forest fragments}, Journal = {Evolutionary Ecology Research}, Volume = {8}, Number = {1}, Pages = {129-148}, Year = {2006}, Month = {January}, ISSN = {1522-0613}, Abstract = {Questions: Does the tendency to join flocks predispose a bird species to local or global extinction? Does the ability to revise particular social preferences in fragmented landscapes confer greater persistence? Do solitary species of birds persist longer in small forest patches? Background: Social carnivores range more widely than solitary carnivores and are more prone to local extinction in fragmented landscapes. Flocking bird species typically range over larger areas than solitary ones, thus potentially encountering threats in and beyond the edges of their habitat more often than solitary species. Data: A 14-year bird-capture database from the Biological Dynamics of Forest Fragments Project (BDFFP) near Manaus, Brazil. Methods: From the literature, from independent field observations and mist-net captures we identified 30 species that join mixed flocks or follow ant swarms. We quantify the tendency for these species to flock both before and after habitat fragmentation. We test the effect of flocking on understory species' persistence in forest fragments of 1, 10 and 100 ha. Results: Species that typically forage in flocks before plot isolation persist for shorter times than those that infrequently join flocks. Species that drop out of flocks after fragmentation persist longer than those that remain in flocks. Our model outperformed a nested analysis of variance that treated each species as a variable, inherently testing for life-history idiosyncrasies and phylogeny.

Refining hotspot conservation means identifying specific locations (individual habitat patches) of realistic size and scale for managers to protect and politicians to support. Because hotspots have lost most of their original habitat, species endemic to them rely on what remains. The issue now becomes identifying where this habitat is and these species are. We accomplished this by using straightforward remote sensing and GIS techniques, identifying specific locations in Brazil's Atlantic Forest hotspot important for bird conservation. Our method requires a regional map of current forest cover, so we explored six popular products for mapping and quantifying forest: MODIS continuous fields and a MODIS land cover (preclassified products), AVHRR, SPOT VGT, MODIS (satellite images), and a GeoCover Landsat thematic mapper mosaic (jpg). We compared subsets of these forest covers against a forest map based on a Landsat enhanced thematic mapper. The SPOT VGT forest cover predicted forest area and location well, so we combined it with elevation data to refine coarse distribution maps for forest endemic birds. Stacking these species distribution maps enabled identification of the subregion richest in threatened birds-the lowland forests of Rio de Janeiro State. We highlighted eight priority fragments, focusing on one with finer resolved imagery for detailed study. This method allows prioritization of areas for conservation from a region >1 million km2 to forest fragments of tens of square kilometers. To set priorities for biodiversity conservation, coarse biological information is sufficient. Hence, our method is attractive for tropical and biologically rich locations, where species location information is sparse. ©2005 Society for Conservation Biology.}, Doi = {10.1111/j.1523-1739.2005.00307.x}, Key = {ISI:000233938100035} } @article{ISI:000231099900030, Author = {Pimm, SL and Jenkins, C}, Title = {Sustaining the variety of life}, Journal = {SCIENTIFIC AMERICAN}, Volume = {293}, Number = {3}, Pages = {66-73}, Year = {2005}, Month = {September}, ISSN = {0036-8733}, Abstract = {The four laws of biogeography describe species abundance and species location,i.e. biodiversity, worldwide.

The answer is "surely not always," since some disturbances may be so devastating that recovery will be impossible. If communities do recover, then how fast is that recovery? Do different subsets of species return at the same rate? Is that rate a simple exponential recovery - meaning that the change toward the original state is fastest when the community is furthest away and it slows as the community converges? Or is recovery a more dynamically complex process? These questions are theoretically interesting and practically important. The theoretical questions are if there is a particular state - some exact composition - to which a community is likely to return, if there might be several (or many) possible such states, or if community composition is essentially haphazard. The practical implication is that if disturbed ecological communities do not tend to return to a previous state, it may be impossible to undo human impacts on natural ecosystems. We follow the fate of species assemblages following the removal of vegetation for mining. We show that these assemblages in restored subtropical coastal dune forests in South Africa do converge with a regional equilibrium state and that convergence is possible within a reasonable period. However, changes in assemblages from different trophic levels were idiosyncratic: convergence in the dung beetle assemblage did not mimic convergence for trees and birds, for example. Few of the assemblages converged exponentially, the simplest shape for the decay function. Furthermore, trends were sometimes different for different indices of community dissimilarity, suggesting that whether one accepts convergence depends, in part, on exactly what one measures. © 2005 by the Ecological Society of America.}, Doi = {10.1890/03-0836}, Key = {ISI:000227659700015} } @article{harris2005refining, Author = {Harris, G.M. and Jenkins, C.N. and Pimm, S.L.}, Title = {Refining biodiversity conservation priorities}, Journal = {Conservation Biology}, Volume = {19}, Number = {6}, Pages = {1957--1968}, Publisher = {Wiley Online Library}, Year = {2005}, Key = {harris2005refining} } @article{wassenaar2005community, Author = {Wassenaar, TD and Van Aarde and RJ and Pimm, SL and Ferreira, SM}, Title = {Community convergence in disturbed subtropical dune forests}, Journal = {Ecology}, Volume = {86}, Number = {3}, Pages = {655--666}, Publisher = {Eco Soc America}, Year = {2005}, Key = {wassenaar2005community} } @article{pimm2005sustaining, Author = {Pimm, S.L. and Jenkins, C.}, Title = {Sustaining the variety of life}, Journal = {Scientific American}, Volume = {293}, Number = {3}, Pages = {66--73}, Publisher = {Nature Publishing Group}, Year = {2005}, Key = {pimm2005sustaining} } @article{pimm2005ecology, Author = {Pimm, SL}, Title = {ECOLOGY IN THE LARGE: GAIA AND GENGHIS KHAN'}, Journal = {Narrow Roads of Gene Land: the Collected Papers of Wd Hamilton Volume 3: Last Words}, Publisher = {Oxford University Press, USA}, Year = {2005}, Key = {pimm2005ecology} } @article{pimm2005categories, Author = {Pimm, SL and Lawton, JH and Cohen, JE}, Title = {CATEGORIES OF PLANKTON}, Journal = {Water Encyclopedia: Oceanography; Meteorology; Physics and Chemistry; Water Law; and Water History, Art, and Culture}, Volume = {4}, Pages = {154}, Publisher = {Wiley-Interscience}, Year = {2005}, Key = {pimm2005categories} } @article{pimm2005biodiversidad, Author = {Pimm, SL and Jenkins, C}, Title = {BIODIVERSIDAD-Conservaci{\'o}n de la biodiversidad-De la investigaci{\'o}n sobre la distribuci{\'o}n geogr{\'a}fica de la biodiversidad y sobre el riesgo de extinci{\'o}n de especies pueden extraerse planes de conservaci{\'o}n eficaces y econ{\'o}micamente viables.}, Journal = {Investigaci{\'O}N Y Ciencia: Edici{\'O}N Espa{\~N}Ola De Scientific American}, Number = {350}, Pages = {34-41}, Year = {2005}, Key = {pimm2005biodiversidad} } @article{pimm2005sustaining, Author = {PIMM, SL and JENKINS, C}, Title = {SUSTAINING THE}, Journal = {Scientific American}, Year = {2005}, Key = {pimm2005sustaining} } @article{ISI:000225737300024, Author = {Harris, GM and Pimm, SL}, Title = {Bird species' tolerance of secondary forest habitats and its effects on extinction}, Journal = {Conservation Biology : the Journal of the Society for Conservation Biology}, Volume = {18}, Number = {6}, Pages = {1607-1616}, Publisher = {WILEY}, Year = {2004}, Month = {December}, ISSN = {0888-8892}, url = {http://dx.doi.org/10.1111/j.1523-1739.2004.00157.x}, Abstract = {Intense deforestation causes massive species losses.

Specifically, we examine the way in which this relationship follows from the niche hierarchy model, whose fundamental assumption is a direct connection between abundances and underlying hierarchical community organization. We test three important, although correlated, predictions of the niche hierarchy model and show that they are upheld in a set of 11 communities (encompassing fishes, amphibians, lizards, and birds) where both abundances and dendrograms were reported. First, species that are highly nested in the dendrogram are on average less abundant than species from branches less subdivided. Second, and more significantly, more equitable community abundances are associated with more evenly branched dendrogram structures, whereas less equitable abundances are associated with less even dendrograms. This relationship shows that abundance patterns can give insight into less visible aspects of community organization. Third, one can recover the distribution of proportional abundances seen in assemblages containing two species by treating each branch point in the dendrogram as a two-species case. This reconstruction cannot be achieved if abundances and the dendrogram are unrelated and suggests a method for hierarchically decomposing systems. To our knowledge, this is the first test of a species abundance model based on nontrivial predictions as to the origins and causes of abundance patterns, and not simply on the goodness-of-fit of distributions.}, Doi = {10.1073/pnas.0831096100}, Key = {fds279426} } @article{ISI:000182170100005, Author = {Jenkins, CN and Powell, RD and Bass, OL and Pimm, SL}, Title = {Demonstrating the destruction of the habitat of the Cape Sable seaside sparrow (Ammodramus maritimus mirabilis)}, Journal = {ANIMAL CONSERVATION}, Volume = {6}, Number = {Part 1}, Pages = {29-38}, Year = {2003}, Month = {February}, ISSN = {1367-9430}, Abstract = {The Cape Sable seaside sparrow (Ammodramus maritimus mirabilis) is Federally protected under the Endangered Species Act of the United States of America.

From those declining numbers, we derive a scaling rule for the time it takes to lose half the species in a fragment as a function of its area.

Specifically, we examine the way in. which this relationship follows from the niche hierarchy model, whose fundamental assumption is a direct connection between abundances and underlying hierarchical community organization. We test three important, although correlated, predictions of the niche hierarchy model and show that they are upheld in a set of 11 communities (encompassing fishes, amphibians, lizards, and birds) where both abundances and dendrograms were reported. First, species that are highly nested in the dendrogram are on average less abundant than species from branches less subdivided. Second, and more significantly, more equitable community abundances are associated with more evenly branched dendrogram structures, whereas less equitable abundances are associated with less even dendrograms. This relationship shows that abundance patterns can give insight into less visible aspects of community organization. Third, one can recover the distribution of proportional abundances seen in assemblages containing two species by treating each branch point in the dendrogram as a two-species case. This reconstruction cannot be achieved if abundances and the dendrogram are unrelated and suggests a method for hierarchically decomposing systems.

Once seeded, half of the plots were left alone to develop without subsequent reseeding. To provide multiple opportunities for establishment, we reseeded the remaining plots with any target species that failed to establish after two growing seasons. There were two 16 _xt 16 m (256 m2) replicates per treatment established in 1994 and 1996 on former agricultural land. Annually, we measured total species richness and evenness, total cover, and establishment success defined as target species richness and total percentage cover by target species, collectively. In some instances, significant treatment x year interactions indicated that treatment effects on variables varied among years. Both richness and rate of establishment of target communities were higher in the more species-rich mixtures. Moreover, richness of resident species in the plots declined with increasing target species richness. Reseeding had no measurable effect on any of the variables, nor on the eventual establishment of target communities or individual target species.

Critics challenge this. Perhaps giving them more credit than they deserve, I examine four concerns. First, that the extinction crisis is not real. It is and high rates of extinction are the rule, not the exception, within well-known taxa. The second criticism dismisses the problem as one restricted just to islands. It is not. Island species have special vulnerabilities, but they are far more locally abundant within their ranges than are continental species with the same range size. There are large numbers of locally rare, continental species with small geographic ranges that are threatened by human impacts. A third criticism notes the few species that became extinct following the clearing of forests from eastern North America in the 19th century, casting doubt upon the relationship between habitat loss and species loss. Analysis of this case history shows that exactly as many species of birds were lost as expected, for the region had very few species to lose. Extensions to species-rich areas such as Southeast Asia and the Atlantic coast of Brazil confirm the expected calibrations with an interesting caveat. Forest losses predict the number of threatened species - those on the verge of extinction - not the number of extinctions. This leads to the final criticism: that there have been too few recent extinctions. The reply is that in these regions the deforestation is more recent and species do not go extinct immediately. Some doomed species can linger for decades - as did the now-extinct species in eastern North America.}, Doi = {10.2307/3298563}, Key = {ISI:000176821200007} } @article{piper2002creation, Author = {Piper, JK and Pimm, SL}, Title = {The creation of diverse prairie-like communities}, Journal = {Community Ecology}, Volume = {3}, Number = {2}, Pages = {205--216}, Publisher = {Akad{\'e}miai Kiad{\'o}}, Year = {2002}, Key = {piper2002creation} } @article{pimm2002dodo, Author = {Pimm, S.L.}, Title = {The dodo went extinct (and other ecological myths)}, Journal = {Annals of the Missouri Botanical Garden}, Pages = {190--198}, Publisher = {JSTOR}, Year = {2002}, Key = {pimm2002dodo} } @article{russell2002effect, Author = {Russell, G.J. and Bass Jr and O.L. and Pimm, S.L.}, Title = {The effect of hydrological patterns and breeding-season flooding on the numbers and distribution of wading birds in Everglades National Park}, Journal = {Animal Conservation}, Volume = {5}, Number = {3}, Pages = {185--199}, Publisher = {Wiley Online Library}, Year = {2002}, Key = {russell2002effect} } @article{pimm2002lost, Author = {Pimm, S}, Title = {The Lost World of the Moa: Prehistoric Life of New Zealand, Trevor H Worthy \& Richard N Holdaway}, Journal = {Nature London}, Pages = {361-361}, Publisher = {MACMILLAN MAGAZINES LTD}, Year = {2002}, Key = {pimm2002lost} } @article{pimm2002range, Author = {Pimm, SL and Bass Jr and OL}, Title = {Range-wide risks to large populations: the Cape Sable sparrow as a case history}, Journal = {Population Viability Analysis}, Pages = {406-424}, Publisher = {The University of Chicago Press}, Year = {2002}, Key = {pimm2002range} } @article{pimm2002no, Author = {Pimm, S}, Title = {No more moa}, Journal = {Nature}, Volume = {420}, Number = {6914}, Pages = {361-361}, Publisher = {NATURE PUBLISHING GROUP}, Year = {2002}, Key = {pimm2002no} } @article{ISI:000179494700017, Author = {Pimm, S}, Title = {The lost world of the moa: prehistoric life of New Zealand}, Journal = {Nature}, Volume = {420}, Number = {6914}, Pages = {361}, Year = {2002}, ISSN = {0028-0836}, Key = {ISI:000179494700017} } @article{fds279418, Author = {Pimm, SL}, Title = {Hat die viefalt des lebens auf der erde eine zukunft?}, Journal = {Nature Und Kultur}, Volume = {3}, Pages = {3-33}, Year = {2002}, Key = {fds279418} } @article{ISI:000171139400024, Author = {Pimm, SL and Ayres, M and Balmford, A and Branch, G and Brandon, K and Brooks, T and Bustamante, R and Costanza, R and Cowling, R and Curran, LM and Dobson, A and Farber, S and da Fonseca, GA and Gascon, C and Kitching, R and McNeely, J and Lovejoy, T and Mittermeier, RA and Myers, N and Patz, JA and Raffle, B and Rapport, D and Raven, P and Roberts, C and Rodriguez, JP and Rylands, AB and Tucker, C and Safina, C and Samper, C and Stiassny, ML and Supriatna, J and Wall, DH and Wilcove, D}, Title = {Environment.

We determine what fraction of species is threatened with extinction within the combinations of these three measures.

For a given range size, lowland species suffer higher levels of threat than island or montane species. (This is counter to the intuition that island species - and those isolated on mountain tops - might be ecologically naïve.) When all three factors are considered together, there is only a slight tendency for lowland species to be disproportionately more threatened. Simply, island and montane species tend to be relatively common within their restricted ranges and their increased abundance reduces their likelihood of being threatened. Elevation is a consistent but relatively unimportant factor in determining threat; abundance and range size are much more important, and have an interactive effect on threatened status.

The PWS model was a cohesive synthesis of the overall biotic community with a focus on energy flow structure, and response to perturbations, both natural and anthropogenic. Forty-eight biotic components were included in the PWS model ranging from life stages of individual species to aggregated functional groups. These groups were organized into primary producers, zooplankton, benthic invertebrates, planktivorous "forage fishes", larger fishes, birds, mammals, and detritus, for the purpose of model documentation. Estimates of biomass flows related to fisheries landings and discards in Prince William Sound were also incorporated. Outputs of the Ecopath model included biomass and flux estimates for individual groups that were refined through the collaborative mass-balancing approach, and useful characterizations of the whole food web. The outputs of Ecosim and Ecospace, which include simulations of population trajectories through time, and habitat-based re-distributions of organisms in space, were also featured. The Ecopath model of PWS could be used to help guide future research programs in the region, to help assess impacts of the EVOS, and to help resource agencies and local communities achieve ecosystem-based conservation and management in the face of increasing human activities in the region. This approach could also be used to help distinguish the relative importance of physical forces and tropic forces in marine ecosystems.}, Key = {fds279125} } @article{ISI:000084482000016, Author = {Pimm, SL}, Title = {Seeing both the woods and the trees}, Journal = {Nature}, Volume = {402}, Number = {6764}, Pages = {853-854}, Publisher = {Springer Science and Business Media LLC}, Year = {1999}, Month = {December}, ISSN = {0028-0836}, url = {http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000084482000016&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=47d3190e77e5a3a53558812f597b0b92}, Doi = {10.1038/47183}, Key = {ISI:000084482000016} } @article{ISI:000084218700001, Author = {Brooks, TM and Pimm, SL and Kapos, V and Ravilious, C}, Title = {Threat from deforestation to montane and lowland birds and mammals in insular South-east Asia}, Journal = {The Journal of Animal Ecology}, Volume = {68}, Number = {6}, Pages = {1061-1078}, Publisher = {WILEY}, Year = {1999}, Month = {November}, ISSN = {0021-8790}, url = {http://dx.doi.org/10.1046/j.1365-2656.1999.00353.x}, Abstract = {1. A reduction in forest area should result in a reduction of its number of species and, moreover, do so in a characteristic way according to the familiar species-area relationship. Brooks, Pimm and Collar (1997) applied this formula to the losses in forest area in the Philippines and Indonesia. Independently derived totals of the number of endemic bird species that are threatened with extinction broadly agree with these predicted losses. In some cases, however, predicted losses overestimate or underestimate the actual numbers of threatened species. 2. Within an island, the proportionate deforestation to date might be most extensive where there are many endemic species, or where there are few. To test this possibility, we obtained recent forest cover data for the region. We separated lowland (< 1000 m a.s.l.) from montane (> 1000 m a.s.l.) forest cover by overlaying topographic maps. From these data, we predict separately the numbers of montane and lowland endemic bird species likely to become extinct as a result of deforestation. We then compared these totals with the numbers considered threatened in the latest Red List. 3. Our predictions based on deforestation closely match the numbers of threatened endemic birds in the lowlands, but underestimate them in montane regions. 4. Our predictions based on deforestation underestimate the number of threatened montane mammal species even more seriously. 5. Lowland faunas of insular South-east Asia are under extreme threat because of massive deforestation. The region's montane faunas appear seriously threatened even by low levels of deforestation.}, Doi = {10.1046/j.1365-2656.1999.00353.x}, Key = {ISI:000084218700001} } @article{ISI:000082821400026, Author = {Brooks, TM and Pimm, SL and Oyugi, JO}, Title = {Time lag between deforestation and bird extinction in tropical forest fragments}, Journal = {Conservation Biology : the Journal of the Society for Conservation Biology}, Volume = {13}, Number = {5}, Pages = {1140-1150}, Publisher = {WILEY}, Year = {1999}, Month = {October}, ISSN = {0888-8892}, url = {http://dx.doi.org/10.1046/j.1523-1739.1999.98341.x}, Abstract = {Tropical forests are becoming increasingly fragmented, threatening the survival of the species that depend on them. Small, isolated forest fragments will lose some of their original species. What is uncertain is how long this process of faunal relaxation will take. We compiled data on birds in five tropical forest fragments in Kakamega Forest, Kenya, of known date of isolation. We then predicted the original and eventual species richness of these fragments and, from this difference, the eventual species losses. Expressing the losses to date as a fraction of eventual losses suggests that faunal relaxation approximates an exponential decay with a half-life of approximately 50 years for fragments of roughly 1000 ha. In other words, in the first 50 years after isolation, tropical forest fragments of this size suffer half of the total number of extinctions that they are likely to experience. This result sets the time scale over which humanity must take conservation action in fragmented tropical forests, may aid efforts to set priorities, and indicates how high the future global extinction rate will be.}, Doi = {10.1046/j.1523-1739.1999.98341.x}, Key = {ISI:000082821400026} } @article{ISI:000080427400055, Author = {Manne, LL and Brooks, TM and Pimm, SL}, Title = {Relative risk of extinction of passerine birds on continents and islands}, Journal = {Nature}, Volume = {399}, Number = {6733}, Pages = {258-261}, Publisher = {Springer Nature}, Year = {1999}, Month = {May}, ISSN = {0028-0836}, url = {http://dx.doi.org/10.1038/20436}, Abstract = {Greater numbers and higher proportions of recent species extinctions have been on islands rather than on continents. In contrast, predictions of massive future extinctions stem from the current clearing of continental, tropical forests. For instance, since 1600, 97 out of 108 bird extinctions have been on islands. However, 452 of the total 1,111 species currently considered to be threatened are continental. Island flora and fauna are uniquely vulnerable to the human introduction of previously absent predators, diseases and other menaces, whereas species on continents are not so ecologically naive. So could predictions of future continental extinctions based on island histories be exaggerated? Most threatened species have small geographic ranges, and the ranges of island species are inevitably smaller than those of continental species. For a given range size, how do the proportions of threatened island and continental species compare? Here we compile the ranges of the passerine (perching) birds of the Americas. Corrected for range size, continental species are more-not less-likely to be threatened. We use this unexpected vulnerability of continental species with small ranges to produce a map showing where species losses might occur in the long term.}, Doi = {10.1038/20436}, Key = {ISI:000080427400055} } @article{fds279123, Author = {Pimm, SL and Askins, RA}, Title = {Forest losses predict bird extinctions in eastern North America}, Journal = {Ncasi Technical Bulletin}, Volume = {2}, Number = {781}, Pages = {420}, Year = {1999}, Month = {May}, Abstract = {A study was conducted to analyze the distribution of bird species and the timing and extent of forest loss in eastern North America.

Killing elephants is highly controversial. The Board must balance this controversy against the probable destruction of vegetation and the consequent depletion of biological diversity that high elephant densities cause. Annual aerial counts provided the population estimates on which the culling quotas were based. For management purposes, the elephant population of the Park is divided into four sub-populations. From 1984 to 1994, the annual quota was usually taken from only one of these sub-populations during a given year. This resulted in 3 to 5 years elapsing between culls in each sub-population. We investigated the year-to-year changes in densities after culling. These changes were density dependent. Density dependence implies that immediate culls following estimated high densities may be premature. If left alone, the densities would decline naturally. Indeed, culling becomes self-reinforcing as it moves population densities towards the level where reproduction is greatest. Data confirm this intuition: at densities greater than 0.37 elephants/km2 elephant numbers generally declined without culling. Many culls were unnecessary. Culling, as implemented in the past, may have had consequences for elephants and their habitat that were different to those expected from a mere reduction in their numbers. Densities in the year immediately after a cull tended to decline - not increase as would be expected from density dependence alone. Undoubtedly, this unexpected decline was the consequence of disturbance and subsequent emigration. In following years, the densities rose as animals moved back into the sub-population.

The PWS model was a cohesive synthesis of the overall biotic community with a focus on energy flow structure, and response to perturbations, both natural and anthropogenic. Forty-eight biotic components were included in the PWS model ranging from life stages of individual species to aggregated functional groups. These groups were organized into primary producers, zooplankton, benthic invertebrates, planktivorous "forage fishes", larger fishes, birds, mammals, and detritus, for the purpose of model documentation. Estimates of biomass flows related to fisheries landings and discards in Prince William Sound were also incorporated. Outputs of the Ecopath model included biomass and flux estimates for individual groups that were refined through the collaborative mass-balancing approach, and useful characterizations of the whole food web. The outputs of Ecosim and Ecospace, which include simulations of population trajectories through time, and habitat-based re-distributions of organisms in space, were also featured. The Ecopath model of PWS could be used to help guide future research programs in the region, to help assess impacts of the EVOS, and to help resource agencies and local communities achieve ecosystem-based conservation and management in the face of increasing human activities in the region. This approach could also be used to help distinguish the relative importance of physical forces and tropic forces in marine ecosystems.}, Key = {fds279124} } @article{pimm1999terrestrial, Author = {Pimm, SL}, Title = {Terrestrial Ecoregions of North America: A Conservation Assessment, TH Ricketts et al.}, Journal = {Nature London}, Pages = {853-853}, Publisher = {MACMILLAN MAGAZINES LTD}, Year = {1999}, Key = {pimm1999terrestrial} } @article{pimm1999seeing, Author = {Pimm, SL}, Title = {Seeing both the woods and the trees}, Journal = {Nature}, Volume = {402}, Number = {6764}, Pages = {853-854}, Publisher = {NATURE PUBLISHING GROUP}, Year = {1999}, Key = {pimm1999seeing} } @article{pimm1999dynamics, Author = {Pimm, SL}, Title = {The dynamics of the flows of matter and energy}, Journal = {Advanced Ecological Theory}, Pages = {172-193}, Publisher = {Wiley Online Library}, Year = {1999}, Key = {pimm1999dynamics} } @article{lockwood1999does, Author = {Lockwood, JL and Pimm, SL}, Title = {When does restoration succeed}, Journal = {Ecological Assembly Rules: Perspectives, Advances, Retreats}, Pages = {363-392}, Publisher = {Cambridge University Press Cambridge}, Year = {1999}, Key = {lockwood1999does} } @article{ISI:000076100300010, Author = {Manne, LL and Pimm, SL and Diamond, JM and Reed, TM}, Title = {The form of the curves: A direct evaluation of Macarthur and Wilson's classic theory}, Journal = {The Journal of Animal Ecology}, Volume = {67}, Number = {5}, Pages = {784-794}, Publisher = {WILEY}, Year = {1998}, Month = {September}, ISSN = {0021-8790}, url = {http://dx.doi.org/10.1046/j.1365-2656.1998.00241.x}, Abstract = {1.

To prevent damage to the Park's ecosystems, the management has culled about 7% of the population annually. Such culls are very controversial. At first glance, contraceptives seem an attractive alternative means of control. We examine contraception as a management option, review the relevant aspects of elephant reproduction, physiology and demography and conclude that this optimism is probably misplaced. First, contraceptives have a wide range of physiological and behavioural side-effects that may prove to be damaging to the individual female and those around her. Second, the elephants in the Park have near-maximal growth rates with inter-calving intervals of less than four years. To achieve zero population growth, about three-quarters of the adult female elephants would need to be on contraceptives. There are no simple alternatives. The smallest numerical target for controlling population numbers is to kill or sterilize females about to become pregnant for the first time. Such a solution is unlikely to appease those who consider killing elephants to be unethical. It may, however, be the one closest to the natural patterns of elephant mortality.}, Doi = {10.1017/S1367943098000018}, Key = {ISI:000204810300001} } @article{ISI:000204810200004, Author = {Nott, MP and Bass, OL and Fleming, DM and Killeffer, SE and Fraley, N and Manne, L and Curnutt, JL and Brooks, TM and Powell, R and Pimm, SL}, Title = {Water levels, rapid vegetational changes, and the endangered Cape Sable seaside-sparrow}, Journal = {Animal Conservation}, Volume = {1}, Number = {1}, Pages = {23-32}, Publisher = {WILEY}, Year = {1998}, Month = {January}, ISSN = {1367-9430}, url = {http://dx.doi.org/10.1017/S1367943098001036}, Abstract = {The legally endangered Cape Sable seaside-sparrow (Ammodramus maritimus mirabilis) is restricted to short-hydroperiod, marl prairies within Florida's Everglades National Park and Big Cypress National Preserve.

The sparrow population decreased by 58% between 1992 and 1995, with the near extinction of the western half of the population and the temporary local extinction of some eastern populations. Other similar grassland sparrows have populations that vary considerably from year to year. Yet the decline in the western subpopulation and the local extinction of some of the peripheral populations cannot be explained by natural variability alone. Hurricane Andrew passed over several subpopulations prior to the particularly poor year of 1993. However, the geographical and temporal patterns of subpopulation decline are not consistent with what would be expected following a hurricane. Frequent fires prevent successful breeding as does flooding during the breeding season. Better management can prevent frequent fires and episodic flooding. However, the long-term survival of the sparrow depends on managing the unanticipated risks that attend its small, fragmented population.}, Doi = {10.1017/S1367943098001024}, Key = {ISI:000204810200003} } @article{manne1998form, Author = {Manne, L.L. and Pimm, S.L. and Diamond, J.M. and Reed, T.M.}, Title = {The form of the curves: a direct evaluation of MacArthur \& Wilson's classic theory}, Journal = {Journal of animal ecology}, Volume = {67}, Number = {5}, Pages = {784--794}, Publisher = {Wiley Online Library}, Year = {1998}, Key = {manne1998form} } @article{whyte1998managing, Author = {Whyte, I. and Aarde, R. and Pimm, S.L.}, Title = {Managing the elephants of Kruger National Park}, Journal = {Animal Conservation}, Volume = {1}, Number = {2}, Pages = {77--83}, Publisher = {Wiley Online Library}, Year = {1998}, Key = {whyte1998managing} } @article{pimm1998managing, Author = {Pimm, SL}, Title = {Managing nature by coin tossing}, Journal = {South African journal of science}, Volume = {94}, Number = {7}, Publisher = {Open Journals Publishing}, Year = {1998}, Key = {pimm1998managing} } @article{nott1998water, Author = {Nott, M.P. and Bass Jr and O.L. and Fleming, D.M. and Killeffer, S.E. and Fraley, N. and Manne, L. and Curnutt, J.L. and Brooks, T.M. and Powell, R. and Pimm, S.L.}, Title = {Water levels, rapid vegetational changes, and the endangered Cape Sable seaside-sparrow}, Journal = {Animal Conservation}, Volume = {1}, Number = {1}, Pages = {23--32}, Publisher = {Wiley Online Library}, Year = {1998}, Key = {nott1998water} } @article{pimm1998extinction, Author = {Pimm, SL}, Title = {Extinction}, Journal = {Conservation Science and Action}, Pages = {20-38}, Publisher = {Wiley Online Library}, Year = {1998}, Key = {pimm1998extinction} } @article{mayer1998integrating, Author = {Mayer, AL and Pimm, SL}, Title = {Integrating endangered species protection and ecosystem management: the Cape Sable seaside sparrow as a case study}, Journal = {Conservation in a Changing World}, Year = {1998}, Key = {mayer1998integrating} } @article{pimm19982, Author = {Pimm, SL}, Title = {2.1 The human future and extinctions: crisis or conspiracy?}, Journal = {Conservation Science and Action}, Pages = {20}, Publisher = {WILEY-BLACKWELL}, Year = {1998}, Key = {pimm19982} } @article{curnutt1998population, Author = {Curnutt, JL and Mayer, AL and Brooks, TM and Manne, L and Bass, OL and Fleming, DM and Nott, MP and Pimm, SL}, Title = {Population dynamics of the endangered Cape Sable seaside-sparrow}, Journal = {Animal Conservation}, Volume = {1}, Number = {01}, Pages = {11-21}, Publisher = {CAMBRIDGE UNIV PRESS}, Year = {1998}, Key = {curnutt1998population} } @article{ISI:A1997XK26500017, Author = {Mayer, AL and Pimm, SL}, Title = {Tropical rainforests: diversity begets diversity.}, Journal = {Current Biology : Cb}, Volume = {7}, Number = {7}, Pages = {R430-R432}, Year = {1997}, Month = {July}, ISSN = {0960-9822}, url = {http://www.ncbi.nlm.nih.gov/pubmed/9210362}, Abstract = {Tropical rainforests exhibit an extraordinarily high level of biological diversity.

We then used the species-area relationship to calculate the number of species predicted to become globally extinct following deforestation on these islands. Next, we counted the numbers of insular southeast Asian endemic bird species considered threatened-i.e., those having 'a high probability of extinction in the wild in the medium-term future'-in the latest summary Red Data Book. The numbers of extinctions predicted from deforestation and the numbers of species actually threatened are strikingly similar.

All the extinctions are indirectly attributable to human impact. Nonetheless, it has proved extremely difficult to specify which of several possible mechanisms caused each particular extinction. This seems to admit defeat in the battle to understand past extinctions. Such understanding could guide our efforts to protect species that are now threatened with extinction. Will it be easier to understand the causes of future extinctions? Surveys of future extinctions stress habitat destruction as the simple and dominant mechanism. This contrasts to its secondary (and generally confused) role in past extinctions. I argue that this contrast between the complexity of the past and the apparent simplicity of the future arises because extinction mechanisms are inherently synergistic. Once extensive species losses begin, it may be impossible to separate the mechanisms and thus manage an individual species as if its decline had a single cause.}, Doi = {10.1007/BF00052716}, Key = {ISI:A1996VH80800004} } @article{ISI:A1996TQ16900034, Author = {Pimm, SL}, Title = {Designer ecosystems}, Journal = {Nature}, Volume = {379}, Number = {6562}, Pages = {217-218}, Publisher = {Springer Science and Business Media LLC}, Year = {1996}, Month = {January}, ISSN = {0028-0836}, url = {http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:A1996TQ16900034&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=47d3190e77e5a3a53558812f597b0b92}, Doi = {10.1038/379217a0}, Key = {ISI:A1996TQ16900034} } @article{ISI:A1996TR29400016, Author = {Manne, L and Pimm, SL}, Title = {Ecology: engineered food webs.}, Journal = {Current Biology : Cb}, Volume = {6}, Number = {1}, Pages = {29-31}, Year = {1996}, Month = {January}, ISSN = {0960-9822}, url = {http://www.ncbi.nlm.nih.gov/pubmed/8825521}, Abstract = {An important new study shows that, in a food web, the strengths and arrangement of the interactions between species are determining factors of stability of the system.}, Doi = {10.1016/s0960-9822(02)00414-1}, Key = {ISI:A1996TR29400016} } @article{ISI:A1996UX38900018, Author = {Morton, RD and Law, R and Pimm, SL and Drake, JA}, Title = {On models for assembling ecological communities}, Journal = {Oikos}, Volume = {75}, Number = {3}, Pages = {493-499}, Publisher = {JSTOR}, Year = {1996}, Month = {January}, ISSN = {0030-1299}, url = {http://dx.doi.org/10.2307/3545891}, Abstract = {Previous numerical studies of community assembly have found (1) that invasion resistance increases with time, and (2) that different assembly sequences typically result in different community endpoints. The algorithm used in these studies involved sequential introductions of species coupled with tests for existence of feasible equilibria with local asymptotic stability. In this paper the algorithm is tested against a method based on numerical integration. We show that the algorithm contains serious technical flaws. The algorithm gives the incorrect outcome in many iterations, and correct assembly sequences diverge rapidly from those it predicts. In the light of this, we reassess the earlier work and suggest that results (1) and (2) above should be treated with caution. A more reliable method of community assembly is clearly needed. Numerical integration, although useful for investigating the outcome over small numbers of iterations, is too slow to deal with large, highly replicated, assembly sequences. We suggest that an alternative, based on a criterion of coexistence known as permanence, would be appropriate, as this is relatively fast and reliable.}, Doi = {10.2307/3545891}, Key = {ISI:A1996UX38900018} } @article{ISI:A1996UY43300014, Author = {Curnutt, JL and Pimm, SL and Maurer, BA}, Title = {Population variability of sparrows in space and time}, Journal = {Oikos}, Volume = {76}, Number = {1}, Pages = {131-144}, Publisher = {JSTOR}, Year = {1996}, Month = {January}, ISSN = {0030-1299}, url = {http://dx.doi.org/10.2307/3545755}, Abstract = {The abundance of a species through time and across space, and the variability of that abundance, determines the species' persistence within its geographic range. We investigated the relationship between abundance and variability of nine species of grassland sparrows to uncover their population dynamics across their ranges. Sparrow populations consist of centrally located sites of high abundance with relatively low variability surrounded by sites of low abundance with relatively high variability. These sites are distributed across space such that variability decreases and abundance increases with increasing distance from the edge of a species' geographic range. Population numbers as a whole become increasingly variable over time, but only a portion of the total population heavily influences this increase in variability. For all but one species variability accrued in the areas of highest abundance. Thus, for these sparrows, the edge of the range is sparsely populated and variable, but not increasingly so. We suggest that the spatial and temporal behavior of grassland sparrow populations exhibit a 'source and sink' dynamic where the core of the range 'feeds' the less productive peripheral areas.

Few studies calibrate extinction with habitat reduction. Critics raise doubts about this calibration, noting that there has been extensive clearing of the eastern North American forest, yet only 4 of its approximately 200 bird species have gone extinct. We analyze the distribution of bird species and the timing and extent of forest loss. The forest losses were not concurrent across the region. Based on the maximum extent of forest losses, our calculations predict fewer extinctions than the number observed. At most, there are 28 species of birds restricted to the region. Only these species would be at risk even if all the forests were cleared. Far from providing comfort to those who argue that the current rapid rate of tropical deforestation might cause fewer extinctions than often claimed, our results suggest that the losses may be worse. In contrast to eastern North America, small regions of tropical forest often hold hundreds of endemic bird species.}, Doi = {10.1073/pnas.92.20.9343}, Key = {ISI:A1995RX20000069} } @article{ISI:A1995RK37600008, Author = {Ariño, A and Pimm, SL}, Title = {On the nature of population extremes}, Journal = {Evolutionary Ecology}, Volume = {9}, Number = {4}, Pages = {429-443}, Publisher = {Springer Nature}, Year = {1995}, Month = {July}, ISSN = {0269-7653}, url = {http://dx.doi.org/10.1007/BF01237765}, Abstract = {Much ecology considers only the typical size of a population, yet extreme values may be of particular importance. Unusually low numbers may doom a population to extinction and unusually high numbers may pose an economic threat. Extreme values may also determine the evolutionary traits that predominate. Obviously, even for a fixed variance in annual numbers, the observed maximum and minimum population size will increase the more years that we count the population. Interestingly, over the time scales of available data (<100 years), most animal populations have an observed variance in annual numbers that increases the more consecutive years we use in its calculation. Consequently, populations will meet extreme values more quickly than if the variance were constant. We quantify the increases in variance for diatoms, insects, and vertebrates, first correcting the data for overall differences in variance. Short- and long-lived species are not consistently different. Species that cycle in density have relatively small increases relative to those that do not cycle. Species in marine ecosystems have larger increases than those in terrestrial and freshwater systems. All these results suggest that the system in which a species is embedded - rather the species' own characteristics - plays the crucial role in determining the nature of population extremes. © 1995 Chapman & Hall.}, Doi = {10.1007/BF01237765}, Key = {ISI:A1995RK37600008} } @article{ISI:A1995RK93800004, Author = {PIMM, S}, Title = {BODY COUNT - REPLY}, Journal = {The Sciences}, Volume = {35}, Number = {4}, Pages = {5}, Year = {1995}, Month = {July}, ISSN = {0036-861X}, Key = {ISI:A1995RK93800004} } @article{ISI:A1995RK42700032, Author = {Pimm, SL and Russell, GJ and Gittleman, JL and Brooks, TM}, Title = {The future of biodiversity.}, Journal = {Science (New York, N.Y.)}, Volume = {269}, Number = {5222}, Pages = {347-350}, Year = {1995}, Month = {July}, ISSN = {0036-8075}, url = {http://www.ncbi.nlm.nih.gov/pubmed/17841251}, Abstract = {Recent extinction rates are 100 to 1000 times their pre-human levels in well-known, but taxonomically diverse groups from widely different environments.

We calculated the observed species turnover of the bird communities on 13 small islands off the coast of the British isles and the Republic of lreland for different census intervals. For seven of these islands, the maximum intervals exceeded 80 years. 2. We developed a non-linear, asymptotic model to describe how observed turnover should change with census interval. Our assumptions were traditional ones, based upon the assumption of dynamic equilibrium in familiar island biogeography theory, even though we knew that such equilibrium was rare in these islands. Furthermore, the model considered the average dynamics of the species present and not the dynamics of the individual species. 3. This model showed that neither the observed turnover calculated over different intervals, nor the turnover rate obtained by dividing this observed turnover by the interval, are statistics that permit comparison between islands. Observed turnover increased over time, thus 1-year turnover underestimated the turnovers over a decade or a century. The increase was less than linear, however, so dividing observed turnover by the number of years in its calculation produced a statistic that declined progressively with that number. 4. The model provided a significant overall fit to the data, but underestimated turnover at both the shortest and longest census intervals. We modified the model to reduce the amount of underestimation, by incorporating the long-term changes in the number of species on each island and hence removing the assumption of equilibrium. This non-equilibrium model provided a much improved fit to the data, but it still failed to describe turnover at the very shortest intervals. These, however, are known from other studies to be inflated by individuals-floaters-that nest only once or twice on the islands. 5. The improved, non-equilibrium model made good predictions of the observed turnover over a 4-year interval. These predictions may be used to compare islands, including those for which empirical data on 4-year turnovers are sparse, 6. We divided the non-equilibrium model into an intrinsic and an extrinsic component, representing the influence of within-community and external factors, respectively. 7. Even the intrinsic components of turnover are large, involving differences in species composition of 6-36\% between widely separated censuses. How these intrinsic components of turnover vary from island to island is not clear because previous studies have been unable to compare turnover at different time scales. The number of islands in this study was too few for this purpose and we leave a more broadly based comparison for a future paper.}, Doi = {10.2307/5805}, Key = {ISI:A1995RY35100008} } @article{ISI:A1995QB63700005, Author = {Nott, MP and Rogers, E and Pimm, S}, Title = {Extinction rates.

That they caused many extinctions is well known from fossil finds. The authors estimate how many fossil bird species were missed (roughly half) and so estimate the true extinction rate. The first colonists exterminated roughly half the species on each island group. Some of these extinctions are falsely attributed to the first colonists, because intensive collection often began a half century after the damage initiated by European discovery. Even taken at face value, these recent extinctions are too few. Many species are so critically endangered that we know neither whether they still survive or how to save them. There are fewer recent extinctions and currently endangered species in the islands of the western Pacific, which were the islands occupied first by humans. The species sensitive to human occupation probably died out long ago in these areas. If so, these islands would have lost even more than half of their bird species. -Authors}, Doi = {10.1098/rstb.1994.0047}, Key = {ISI:A1994NM57000005} } @article{ISI:A1994NC16000010, Author = {Pimm, SL and Davis, GE and Loope, L and Roman, CT and Smith, TJII and Tilmant, JT}, Title = {Hurricane Andrew.

Examples in the United States include the 'Alala (Hawaiian Crow; Corvus hawaiiensis) and Northern Spotted Owl (Strix occidentalis caurina). To guide such decisions, we analyze counts of all crow, owl, and hawk species in the most complete available data set: counts of bird breeding pairs on 14 European islands censused for 29-66 consecutive years. The data set yielded 129 records for analysis. We define the population ceiling as the highest number of breeding pairs observed from colonization to extinction, within a consecutive series of counts for a given species on a given island. The resulting distributions of population lifetimes as a function of population size prove to be highly skewed: most small populations disappear quickly, but a few last for a long time. Median (i.e., 50th percentile) lifetimes are calculated as only 1-5 yr for hawk, owl, and crow populations with ceilings of one or two breeding pairs. As expected if demographic accidents are the main cause of extinction for small populations, lifetimes rise by a factor of 3-4 for each additional pair up to three pairs. They rise more slowly thereafter. These observations suggest that lifetimes of the 'Alala (now reduced to about three pairs in the wild), and of populations of Northern Spotted Owl in the smallest forest fragments, will be short unless active management is implemented.}, Doi = {10.1073/pnas.90.22.10871}, Key = {ISI:A1993MH32200095} } @article{ISI:A1993LL95700008, Author = {Pimm, SL}, Title = {Ecosystem dynamics: nature's short, sharp shocks.}, Journal = {Current Biology : Cb}, Volume = {3}, Number = {5}, Pages = {288-290}, Year = {1993}, Month = {May}, ISSN = {0960-9822}, url = {http://www.ncbi.nlm.nih.gov/pubmed/15335751}, Doi = {10.1016/0960-9822(93)90181-m}, Key = {ISI:A1993LL95700008} } @article{ISI:A1993KK57600004, Author = {Pimm, SL}, Title = {Life on an intermittent edge.}, Journal = {Trends in Ecology and Evolution}, Volume = {8}, Number = {2}, Pages = {45-46}, Year = {1993}, Month = {February}, ISSN = {0169-5347}, url = {http://www.ncbi.nlm.nih.gov/pubmed/21236104}, Doi = {10.1016/0169-5347(93)90156-j}, Key = {ISI:A1993KK57600004} } @article{ISI:A1993KF77500026, Author = {Cohen, JE and Beaver, RA and Cousins, SH and DeAngelis, DL and Goldwasser, L and Heong, KL and Holt, RD and Kohn, AJ and Lawton, JH and Martinez, N and O'Malley, R and Page, LM and Patten, BC and Pimm, SL and Polis, GA and Rejmanek, M and Schoener, TW and Schoenly, K and Sprules, WG and Teal, JM and Ulanowicz, RE and Warren, PH and Wilbur, HM and Yodzis, P}, Title = {Improving Food Webs}, Journal = {Ecology}, Volume = {74}, Number = {1}, Pages = {252-258}, Publisher = {WILEY}, Year = {1993}, Month = {January}, ISSN = {0012-9658}, url = {http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:A1993KF77500026&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=47d3190e77e5a3a53558812f597b0b92}, Doi = {10.2307/1939520}, Key = {ISI:A1993KF77500026} } @article{ISI:A1993MA34600014, Author = {Hang-Kwang Luh, and Pimm, SL}, Title = {The assembly of ecological communities: a minimalist approach}, Journal = {The Journal of Animal Ecology}, Volume = {62}, Number = {4}, Pages = {749-765}, Year = {1993}, Month = {January}, ISSN = {0021-8790}, url = {http://dx.doi.org/10.2307/5394}, Abstract = {Communities develop through community assembly, in which species invade, persist, or become extinct. Community assembly is a sequence of different community states. Each state is a unique combination of species' presence or absence. The community transition graph is the directed graph of the transitions between states. The authors investigated the statistical distribution of different community transition graphs that contain varying numbers of species. Does the species composition of a community persist? Or does it cycle, and, if so, through a few recognizable states or through a complex sequence that might appear superificially random? In random transition graphs, the directions of the transitions are specified entirely at random. In a second recipe. all cycles are excluded by assigning each state a random "height'. The community transition graph moves from a "lower' state to one of its "higher' neighbours. This produces landscape transition graphs. A third recipe adds one ecological constraint to the random assembly models. The simple, ecologically implausible cycles are removed to produce minimal transition graphs. Random transition graphs most commonly have one persistent state. Landscape transition graphs commonly have many more persistent states and the number increases rapidly with the number of species in the system. Persistent cycles are rare in the random graphs and are impossible in the landscape graphs. Random graphs may best describe community restoration. If so, restoration might eventually reach its desired persistent community but only after a long period of intermediate cycling. In contrast, if landscape or minimal graphs best decribe restoration, then it would quickly reach a persistent community. Unfortunately, this persistent community may not be the desired community. -from Authors}, Doi = {10.2307/5394}, Key = {ISI:A1993MA34600014} } @article{ISI:A1993MA34600009, Author = {Blackburn, TM and Lawton, JH and Pimm, SL}, Title = {Non-metabolic explanations for the relationship between body size and animal abundance}, Journal = {The Journal of Animal Ecology}, Volume = {62}, Number = {4}, Pages = {694-702}, Publisher = {JSTOR}, Year = {1993}, Month = {January}, ISSN = {0021-8790}, url = {http://dx.doi.org/10.2307/5389}, Abstract = {Metabolic constraints are the usual explanation for the relationship between body size and species abundance in natural assemblages of animals. In some assemblages, abundance scales with body weight to the -0.75 power. Metabolic rate scales as weight raised to the (plus) power, therefore, on average equal amounts of energy are available to each species in a community. This equality has been taken as evidence that a species' abundance is limited by its energetic requirements. But most species in samples of complete assemblages cannot be energy limited (although the most abundant species, at the "upper bound' may be). And arguments also ignore the frequency distributions of species; body size and species; abundance which underlie abundance versus size plots. The authors test the hypothesis that concatenating the underlying frequency distributions of species' body size and species' abundance can directly account for observed patterns in plots of size versus abundance in assemblages of animals, comparing the negative slope of the upper boundary of plots of size against abundance from real assemblages, with the same slopes derived from models with no energy constraints. Models give estimates for the upper bound slopes that are very similar to slopes calculated from real assemblages. Patterns of abundance versus body size in natural assemblages thus may not be constrainted by species' energy requirements, and do not require explanations independent of those for the constituent frequency distributions of size and abundance. -from Authors}, Doi = {10.2307/5389}, Key = {ISI:A1993MA34600009} } @article{ISI:A1993KK04500007, Author = {Cohen, JE and Pimm, SL and Yodzis, P and Saldana, J}, Title = {Body sizes of animal predators and animal prey in food webs}, Journal = {The Journal of Animal Ecology}, Volume = {62}, Number = {1}, Pages = {67-78}, Publisher = {JSTOR}, Year = {1993}, Month = {January}, ISSN = {0021-8790}, url = {http://dx.doi.org/10.2307/5483}, Abstract = {In c90% of the feeding links among the animal species with known sizes, a larger predator consumes a smaller prey. Larger predators eat prey with a wider range of body sizes than do smaller predators. The geometric mean predator size increases with the size of prey. The increase in geometric mean predator size is less than proportional to the increase in prey size (ie has a slope less than one on log-log coordinates). The geometric mean sizes of prey and predators increase as the habitat of webs changes from aquatic to terrestrial to coastal to marine. Within each type of habitat, mean prey sizes are always less than mean predator sizes, and prey and predator sizes are always positively correlated. Feeding relations order the metabolic types of organisms from invertebrate to vertebrate ectotherm to vertebrate endotherm. Organisms commonly eat other organisms with the same or lower metabolic type, but (with very rare exceptions) organisms do not eat other organisms with a higher metabolic type. Mean sizes of prey increase as the metabolic type of prey changes from the invertebrate to vertebrate ectotherm to vertebrate endotherm, but the same does not hold true for predators. Prey and predator sizes are positively correlated in links from invertebrate prey to invertebrate predators. In links with other combinations of prey and predator metabolic types, the correlation between prey and predator body sizes is rarely large when it is positive, and in some cases is even negative. Species sizes are roughly log-normally distributed. Body size offers a good interpretation of the ordering of animal species assumed in the cascade model, a stochastic model of food web structure. When body size is taken as the physical interpretation of the ordering assumed in the cascade model, and when the body sizes of different animal species are taken as log-normally distributed, many of the empirical findings can be explained in terms of the cascade model. -from Authors}, Doi = {10.2307/5483}, Key = {ISI:A1993KK04500007} } @article{cohen1993improving, Author = {Cohen, JE and Beaver, RA and Cousins, SH and DeAngelis, DL and Goldwasser, L. and Heong, KL and Holt, RD and Kohn, AJ and Lawton, JH and Martinez, N. and others}, Title = {Improving food webs}, Journal = {Ecology}, Volume = {74}, Number = {1}, Pages = {252--258}, Publisher = {JSTOR}, Year = {1993}, Key = {cohen1993improving} } @article{pimm1993life, Author = {Pimm, S.L.}, Title = {Life on an intermittent edge.}, Journal = {Trends in ecology \& evolution (Personal edition)}, Volume = {8}, Number = {2}, Pages = {45}, Year = {1993}, Key = {pimm1993life} } @article{cohen1993body, Author = {Cohen, J.E. and Pimm, S.L. and Yodzis, P. and Salda{\~n}a, J.}, Title = {Body sizes of animal predators and animal prey in food webs}, Journal = {Journal of Animal Ecology}, Pages = {67--78}, Publisher = {JSTOR}, Year = {1993}, Key = {cohen1993body} } @article{pimm1993times, Author = {Pimm, S.L. and Diamond, J. and Reed, T.M. and Russell, G.J. and Verner, J.}, Title = {Times to extinction for small populations of large birds}, Journal = {Proceedings of the National Academy of Sciences}, Volume = {90}, Number = {22}, Pages = {10871}, Publisher = {National Acad Sciences}, Year = {1993}, Key = {pimm1993times} } @article{blackburn1993non, Author = {Blackburn, T.M. and Lawton, J.H. and Pimm, S.L.}, Title = {Non-metabolic explanations for the relationship between body size and animal abundance}, Journal = {Journal of Animal Ecology}, Pages = {694--702}, Publisher = {JSTOR}, Year = {1993}, Key = {blackburn1993non} } @article{hang1993assembly, Author = {Hang-Kwang, L. and Pimm, S.L.}, Title = {The assembly of ecological communities: a minimalist approach}, Journal = {Journal of Animal Ecology}, Pages = {749--765}, Publisher = {JSTOR}, Year = {1993}, Key = {hang1993assembly} } @article{gaston1993book, Author = {Gaston, KJ and McArdle, BH and Lawton, JH and Lewinsohn, TM and Compton, SG and Memmott, J. and Godfray, HC and Thomas, CD and Fowler, SV and Syrett, P. and others}, Title = {Book chapters}, Journal = {Brighton Crop Protection Conference-Weeds}, Pages = {753--757}, Year = {1993}, Key = {gaston1993book} } @article{pimm199416, Author = {PIMM, SL}, Title = {BIODIVERSITY AND THE BALANCE OF NATURE}, Journal = {Biodiversity and Ecosystem Function}, Volume = {99}, Pages = {347-359}, Publisher = {Springer}, Year = {1993}, ISBN = {3-540-55804-7}, url = {http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:A1993BZ53F00016&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=47d3190e77e5a3a53558812f597b0b92}, Key = {pimm199416} } @article{pimm1993nature, Author = {Pimm, SL}, Title = {Nature's short, sharp shocks}, Journal = {Current Biology}, Volume = {3}, Number = {5}, Pages = {288-290}, Year = {1993}, Abstract = {A recent experimental study confirms theoretical predictions of how the response of an ecosystem to a perturbation depends on the structure of its food web.}, Key = {pimm1993nature} } @article{pimm1993discussion, Author = {Pimm, SL}, Title = {Discussion: understanding indirect effects: is it possible}, Journal = {Mutualism and Community Organization.

In an unvarying environment, where extinction is caused solely by demographic accidents, the risk of extinction should decrease steeply with K; the greater the contribution of environmental variability to the risk of extinction, the less steep should be the dependence on K. Large-bodies species tend to have long lifetimes but low rates of increase, which have opposite effects on the risk of extinction per year. In comparisons of a large- and small-bodied species at the same average population size (N), the large-bodied species should be at less risk at low N but at greater risk at high N. These predictions were tested using a data base of short-term survivals of 355 populations belonging to 100 species of British land birds on 16 islands. Mean N and risk of extinction are known for these populations, and CVs for 39 species can be calculated. Risk of extinction does decrease sharply with N. After correcting for much of the effect of N, the theoretical prediction is confirmed that the relative susceptibility to extinction of large- and small-bodied species reverses with increasing population size. Above 7 pairs, larger-bodied species are at greater risk than smaller-bodied species; the reverse is true <7 pairs. Migratory species are at greater risk of extinction that resident species. After accounting for the effects of N, body size, and migratory status, the risk of extinction does increase with the CV. -from Authors}, Doi = {10.1086/284889}, Key = {ISI:A1988R471300001} } @article{ISI:A1988P709000063, Author = {Pimm, SL and Redfearn, A}, Title = {The variability of population densities}, Journal = {Nature}, Volume = {334}, Number = {6183}, Pages = {613-614}, Publisher = {Springer Nature}, Year = {1988}, Month = {January}, ISSN = {0028-0836}, url = {http://dx.doi.org/10.1038/334613a0}, Abstract = {The variability of population densities over time (henceforth called population variability) is one of several meanings of ecological stability1.

Forty-nine species have been introduced a total of 111 times to five of the six main islands. There have been 33 extinctions. Our analyses were done at two separate organizational levels: all species introduced to an island; and all forest-dwelling species. If competition determines which species can coexist, and the intensity of competition is correlated with morphological similarity, then the surviving species should be overdispersed in morphological space. Further, sets of surviving species that coexist should be regularly positioned in morphological space. At the island-wide organizational level, the surviving species were neither overdispersed nor regularly positioned in morphological space. However, at the forest-wide level the surviving species were not only highly overdispersed, they were also regularly positioned when compared to randomly assembled communities. © 1987 Chapman and Hall Ltd.}, Doi = {10.1007/BF02067395}, Key = {moulton1987morphological} } @article{ISI:A1987G915000009, Author = {Pimm, SL}, Title = {Determining the effects of introduced species.}, Journal = {Trends in Ecology and Evolution}, Volume = {2}, Number = {4}, Pages = {106-108}, Year = {1987}, Month = {April}, ISSN = {0169-5347}, url = {http://www.ncbi.nlm.nih.gov/pubmed/21227831}, Abstract = {People have moved species around the world for millenia, sometimes by accident, but often with considerable enthusiasm.

Our models expanded traditional Lotka-Volterra models of predator-prey interactions in several ways. We added life history structure to these models in order to investigate its effects. Life history omnivory is different life history stages of a species feeding in trophically different positions in a food web. Such a species might appear omnivorous, integrating across all stages, but the individual stage might not be. Other important additions to the basic models included stock-recruitment relationships between adults and young and food-dependent maturation rates for early life history stages. Complex models of multispecies interactions were built from basic ones by adding new features sequentially. Our analysis revealed five major features of our multispecies, multi-life-stage models. Omnivory reduces stability, as it does in food web models without life history structure. However, life history omnivory reduces stability much less than single life stage omnivory does. Stock recruitment relationships affect the likelihood of finding stable models. If the maturation rate of young varies with their food supply, the chance of finding stable models decreases. Finally, predation loops of the type A eats B, B eats A, or A eats B, B eats C, C eats A greatly reduce model stability. We present both biological and mathematical explanations for these findings. We also discuss their implications for management of marine resources. © 1987.}, Doi = {10.1016/0040-5809(87)90052-9}, Key = {ISI:A1987L357200001} } @article{ISI:A1987K854000004, Author = {Pimm, SL and Kitching, RL}, Title = {The determinants of food chain lengths.}, Journal = {Oikos}, Volume = {50}, Number = {3}, Pages = {302-307}, Publisher = {JSTOR}, Year = {1987}, Month = {January}, ISSN = {0030-1299}, url = {http://dx.doi.org/10.2307/3565490}, Abstract = {Reviews natural variation in the food chains of phytotelmata - water-filled plant-bodies.

If it can, it is likely to drive the subordinate to extinction, leaving a one species system. 2) The subordinate may specialize on clearly inferior resources because the dominant forces it from the better resources. 3) In the distinct-preference case, the scarcity of both resources leads to specialization of both species because interspecific competition (causing specialization) is greater than intraspecific competition (causing generalization). The 3 commonest endemic nectivores in and near the Hawaii Volcanoes National park fed principally on the flowers of Metrosideros collina and Sophora chrysophylla. During the study, Metrosideros went from few flowers per tree to peak bloom, and Sophora did the reverse. Both distinct- and shared-preference cases were noted. The former involved Himatione sanguinea on Metrosideros and Loxops virens on Sophora. The latter involved Vestiaria coccinea (the dominant) and subordinates Himatione and Loxops, with the preferred resources being trees with the highest numbers of flowers. Vestiaria only exploited trees with high numbers of flowers and may have had no alternative. Its competitors were forced onto poorer resources by its presence. These results support the theory's first 2 predictions.

occur is described. The model is similar to one in a companion paper by Rosenzweig in that a heterozygote genotype, involving a new allele, is first selected by virtue of its ability to exploit a new niche and is then eliminated through competition. The superior competitor, which eliminates the heterozygote, is the homozygote for the new allele. For this process to occur the heterozygote must be sufficiently fit to exploit and invade a new niche, but not so fit that a classical polymorphism results from heterozygous advantage. This process of speciation is most likely to occur when there are vacant niches. When and where these might occur are discussed. Copyright © 1979, Wiley Blackwell.

Questions about the 'shape' of the food webs within which these species are embedded are much more rarely asked 2-4. For example, what happens when a population feeds at more than one trophic level (omnivory)? In some real food webs there seem to be no omnivores (Fig. 1a)5; in others omnivores are common6,7 (Fig. 1c)8. In this note we attack the problem of omnivory using simple, linear Lotka-Volterra models of food webs9, and show that certain patterns are much more likely to persist on an evolutionary time scale than others. We then compare the model predictions with real food webs. © 1978 Nature Publishing Group.}, Doi = {10.1038/275542a0}, Key = {ISI:A1978FS34900046} } @article{ISI:A1978GH43900010, Author = {Pimm, SL}, Title = {An experimental approach to the effects of predictability on community structure}, Journal = {Integrative and Comparative Biology}, Volume = {18}, Number = {4}, Pages = {797-808}, Year = {1978}, Month = {September}, ISSN = {0003-1569}, url = {http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:A1978GH43900010&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=47d3190e77e5a3a53558812f597b0b92}, Abstract = {This paper considers the effects of different levels of resource predictability on niche widths, competition and diversity in a community of three hummingbird species. Three pairs of hypotheses are tested: whether decreasing predictability (a) increases or decreases niche width, (b) increases or decreases competition and (c) increases or decreases diversity. The results show that complementary increases and decreases in niche width occur with decreasing predictability, while competition and diversity decrease, at least with extreme unpredictability. A model, which assumes the species to have similar resource preferences, and its predictions are examined.The dominant species, Lampornis clemenciae, excludes a subordinate species, Archilochus alexandri, from preferred resources. This defense becomes unprofitable with decreasing predictability and Archilochus invades the resources once vigorously defended by Lampornis. When the spectrum of resources is altered in the direction of decreasing suitability for both species, Lampornis becomes even more specialized and sensitive to the effects of unpredictability. A third species, Eugenes fulgens, steals resources undefended by Lampornis. These characteristics seem to be common to a number of communities in very different taxonomic groups, and characteristic of communities in which species share a common preferred resource. The question of how a community organized with distinct resource preferences responds to decreasing predictability remains open. © 1978 American Society of Zoologists.}, Doi = {10.1093/icb/18.4.797}, Key = {ISI:A1978GH43900010} } @article{lawton1978population, Author = {Saunders, PT and Lawton, JH and Pimm, SL}, Title = {Population dynamics and the length of food chains}, Journal = {Nature}, Volume = {272}, Number = {5649}, Pages = {189-190}, Publisher = {Nature Publishing Group}, Year = {1978}, Key = {lawton1978population} } @article{pimm1978feeding, Author = {Pimm, SL and Lawton, JH}, Title = {On feeding on more than one trophic level}, Journal = {Nature}, Volume = {275}, Number = {5680}, Pages = {542-544}, Publisher = {Nature Publishing Group}, Year = {1978}, url = {http://dx.doi.org/10.1038/275542a0}, Doi = {10.1038/275542a0}, Key = {pimm1978feeding} } @article{ISI:A1977DP39300034, Author = {Pimm, SL and Lawton, JH}, Title = {Number of trophic levels in ecological communities}, Journal = {Nature}, Volume = {268}, Number = {5618}, Pages = {329-331}, Publisher = {Springer Nature}, Year = {1977}, Month = {December}, ISSN = {0028-0836}, url = {http://dx.doi.org/10.1038/268329a0}, Abstract = {ECOLOGICAL food chains are typically short, consisting of not more than four or five trophic levels.
