The Ecology group of the Biological Sciences Department uses a wide variety of approaches to resolve fundamental issues concerning ecological systems that range from microbes to aquatic and terrestrial communities. Model systems are used to explore diverse questions such as, how plants respond to changing environments, how pollinator-plant interactions shape the evolution of plant mating systems, how resources and trophic interactions structure tropical, temperate and aquatic communities, and how habitat fragmentation impacts ecological interactions and the genetic structure of populations.
