Research Summary:
Re: Project 7 -- Senescence is defined demographically as an increase in mortality after reproductive maturity. Our current understanding of mortality patterns may be limited by the fact that most studies have been made with short-lived model organisms under laboratory conditions. This project uses a new model system, with a relatively long lifespan and unique trajectories of growth and reproduction with age. At the foundation of this project is a population of 30,000 individuals of "Plantago lanceolata," a perennial plant species.
