Research Program


Ecological causes and consequences of variation in biodiversity

My research program is broadly focused on the disciplinary interfaces between population, community and ecosystem ecology in both freshwater and terrestrial systems and has involved work with amphibians, insects, fish, lizards, and herbaceous plants. In particular, I am interested in understanding processes that control the structure (e.g., relative abundances of species, number of species and kinds of species present) of ecological communities and how this structure affects ecosystem function and dynamics of constituent populations. For example, my students and I study how biotic and abiotic factors affect the intensity of species interactions within food webs which can affect the ability of different species to coexist. Understanding the ecological causes and consequences of variation in the biodiversity of food webs is essential if society is interested in conserving biodiversity and predicting the consequences of biodiversity loss.
