My colleagues and I are studying factors determining species composition in marine bottom communities. We are particularly interested in the effects of predation, competition, biological disturbance, introduced species and eutrophication on community structure. Ongoing research projects include examining: 1) ecosystem functions of oyster reefs, including use of oyster reefs as habitat for fish, crabs, shrimp, and benthos as well as the role of oysters in filtering the overlying water column; 2) the relative effects of nutrient addition and predation in determining the composition of benthic communities; 3) indirect effects of interactions among predators for benthic prey using shrimp and fish species as model organisms; 4) the influence of dredging disturbance on bottom communities; 5) factors structuring the benthic communities of estuarine marshes; and 6) restoration of marsh and oyster communities. Most of these projects are interdisciplinary, involving collaboration with researchers from several universities and government agencies.
