Biographical Information:

Mike Vanni is an ecologist studying food webs, ecological stoichiometry, ecosystem ecology and watersheds, with a focus on freshwater ecosystems. Areas of particular interest are the role of animals in recycling and transporting nutrients, both within the context of ecological stoichiometry theory and in terms of impacts at the ecosystem scale; and integrating watersheds and lake ecosystems. Dr. Vanni's approaches include whole-ecosystem studies, manipulative field experiments and simulation modeling. One current project examines how watershed processes mediate the abundance of an important omnivorous fish (gizzard shad). Another project seeks to understand and how watersheds and omnivorous fish interactively regulate lake ecosystems, and how this regulation varies along a gradient of watershed land use. A recently begun project focuses on the role of reservoir ecosystems in watershed-scale carbon budgets, within the context of regional and global carbon cycles.
