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 talented graduate students include disease transmission in New England amphibians (Lauren Ash), occupancy modeling of small mammals and their ectoparasites (Emily Beasley), transmission of amphibian diseases by avian vectors (Ray Looney), the spread of invasive insects and their parasitoids (George Ni), and atmospheric deposition and nutrient stoichiometry of pitcher plants and bromeliads (Lindsey Pett).
