My research addresses basic questions about the organization of animal and plant communities. What are the forces that determine the species composition and abundance of natural assemblages? How do competition and predation affect local community structure? What are the biotic and abiotic factors that control population growth and the risk of extinction? Current research projects include enrichment and tipping points in aquatic ecosystems, effects of climate change on ant assemblages of eastern deciduous forests, and null model analyses of community structure and biodiversity.
Research projects of my graduate students and post-docs include species distribution modeling of New England plants (Lauren Ash), the population dynamics of small mammal assemblages in eastern hemlock forests (Ally Degrassi), temperature adaptation in common woodland ants and their responses to climate change (Andrew Nguyen), and proteomic indicators of tipping points in the aquatic food web of Sarracenia (Amanda Northrop).
