   Abstract = {<h4>Premise</h4>Although Boechera (Boechereae, Brassicaceae)
             has become a plant model system for both ecological genomics
             and evolutionary biology, all previous phylogenetic studies
             have had limited success in resolving species relationships
             within the genus. The recent effective application of
             sequence data from target enrichment approaches to resolve
             the evolutionary relationships of several other challenging
             plant groups prompted us to investigate their usefulness in
             Boechera and Boechereae.<h4>Methods</h4>To resolve the
             phylogeny of Boechera and closely related genera, we
             utilized the Hybpiper pipeline to analyze two combined bait
             sets: Angiosperms353, with broad applicability across
             flowering plants; and a Brassicaceae-specific bait set
             designed for use in the mustard family. Relationships for
             101 samples representing 81 currently recognized species
             were inferred from a total of 1114 low-copy nuclear genes
             using both supermatrix and species coalescence
             methods.<h4>Results</h4>Our analyses resulted in a
             well-resolved and highly supported phylogeny of the tribe
             Boechereae. Boechereae is divided into two major clades, one
             comprising all western North American species of Boechera,
             the other encompassing the eight other genera of the tribe.
             Our understanding of relationships within Boechera is
             enhanced by the recognition of three core clades that are
             further subdivided into robust regional species
             complexes.<h4>Conclusions</h4>This study presents the first
             broadly sampled, well-resolved phylogeny for most known
             sexual diploid Boechera. This effort provides the foundation
             for a new phylogenetically informed taxonomy of Boechera
             that is crucial for its continued use as a model
             system.},

   Title = {Exploring Past and Future Distributions of the Rare
             Appalachian Oak Fern Using MaxEnt Modeling},
   Journal = {American Fern Journal},
   Volume = {113},
   Number = {2},
   Pages = {109-125},

   Abstract = {Abstract . Anthropogenic climate change is projected to have
             an especially negative impact on the survival of plants that
             are dependent on limited microclimatic refugia or that
             already reside at their climatic extreme. Gymnocarpium
             appalachianum is a narrowly endemic fern restricted to cold
             mountaintops and algific vents in the central and southern
             Appalachian region of eastern North America. It is the much
             rarer of the two documented diploid parents of the
             circumboreal allotetraploid G. dryopteris - one of the most
             widespread fern species on the planet. Gymnocarpium
             appalachianum is a good case study for forecasting how
             evolutionarily significant, but rare, species might survive
             on a warming planet. We utilize an ecological niche modeling
             approach (MaxEnt) to explore the projected distribution of
             G. appalachianum under past (Last Glacial Maximum) and
             future climate models. All known verified herbarium records
             of G. appalachianum were georeferenced, for a total of 70
             occurrence points. Nineteen standard bioclimatic variables
             extracted from WorldClim were used to model near-current
             climate projections; representative concentration pathways
             (RCPs 2.6 and 8.5) were used for future climate projections
             (2070). The temperature annual range, mean temperature of
             warmest quarter, precipitation of driest month,
             precipitation of coldest quarter, and mean diurnal range
             were identified as the key variables for shaping the
             distribution of G. appalachianum. An unanticipated result
             from our analyses is that G. appalachianum has past and
             current projected habitat suitability in Alaska. Because
             this overlaps with the current range of G. disjunctum, the
             other diploid parent of G. dryopteris, it suggests a
             possible region of origin for this circumboreal tetraploid
             descendent of G. appalachianum - a research avenue to be
             pursued in the future. Our study envisions a dire fate for
             G. appalachianum; its survival will likely require an urgent
             contingency plan that includes human-mediated population
             relocation to cooler, northern locations. Understanding the
             long-term sustainability of narrowly endemic plants such as
             G. appalachianum is critical in decisions about their
             management and conservation.},

   Title = {An in-depth investigation of cryptic taxonomic diversity in
             the rare endemic mustard Draba maguirei.},
   Journal = {American journal of botany},
   Volume = {110},
   Number = {3},
   Pages = {1-22},
   Year = {2023},
   Month = {March},
   url = {http://dx.doi.org/10.1002/ajb2.16138},
   Abstract = {<h4>Premise</h4>Previously published evidence suggests that
             Draba maguirei, a mustard endemic to a few localities in the
             Bear River, Wellsville, and Wasatch Mountains of northern
             Utah, may represent a cryptic species complex rather than a
             single species. Conservation concerns prompted an in-depth
             systematic study of this taxon and its putative
             relatives.<h4>Methods</h4>Sampling most known populations of
             D. maguirei s.l. (D. maguirei var. maguirei and D. maguirei
             var. burkei), we integrate data from geography, ecology,
             morphology, cytogenetics and pollen, enzyme electrophoresis,
             and the phylogenetic analysis of nuclear internal
             transcribed spacer sequences to explore potential taxonomic
             diversity in the species complex.<h4>Results</h4>Draba
             maguirei var. burkei is shown here to be a distinct species
             (D. burkei) most closely related to D. globosa, rather than
             to D. maguirei. Within D. maguirei s.s., the northern (high
             elevation) and southern (low elevation) population clusters
             are genetically isolated and morphologically
             distinguishable, leading to the recognition here of the
             southern taxon as D. maguirei subsp. stonei.<h4>Conclusions</h4>Our
             study reveals that plants traditionally assigned to D.
             maguirei comprise three genetically divergent lineages (D.
             burkei and two newly recognized subspecies of D. maguirei),
             each exhibiting a different chromosome number and occupying
             a discrete portion of the geographic range. Although
             previously overlooked and underappreciated taxonomically,
             the three taxa are morphologically recognizable based on the
             distribution and types of trichomes present on the leaves,
             stems, and fruit. Our clarification of the diversity and
             distribution of these taxa provides an improved framework
             for conservation efforts.},
