Research Interests

Fish and Mussel Ecology and Management, Conservation Ecology, Production Biology

My research and that of my students centers around fish and mussel ecology, biotic interactions, and impacts of habitat and environmental alterations — especially in the stream environment. The main emphasis of this work has been in identifying physical and biotic influences on the ecological success of aquatic fauna at different spatial, temporal, and organizational scales and quantifying such relationships. This includes studies of population and production dynamics, community interactions, habitat assessment and manipulation, ecotoxicology, food-web functions, density-dependent effects, and empirical and simulation modeling. The ultimate goal of this effort is to incorporate our science into sound ecosystem and fisheries conservation and management.
