Current Research Interests
My group studies linkages between mobile top predators (birds) and aquatic food webs, to guide conservation of important habitats in a changing environment.
Components of this work include
- Laboratory, field, and modeling studies of the energy costs of aquatic birds, and of their intake rates of prey of different species, sizes, and densities
- Use of gut contents, stable isotopes, and fatty acid biomarkers to identify the diets of waterbirds, and the diets of different species in their food webs (invertebrates and fish)
- Spatial simulation models of the foraging energetics of waterbirds, to characterize and delineate areas of habitat capable of supporting these predators
- Network models of food webs to explore how climate-driven changes in temperature, organic inputs, and invasive species might alter the ability of certain habitat areas to sustain the top predators in the long term
