The overall focus of my research efforts has been at the interface between ecology and fisheries/resource management. As such, I address applied problems in fisheries management and resource conservation using concepts and approaches from the basic field of ecology. In an effort to understand community patterns in freshwater systems, such that informed management decisions can be made, I have used a variety of approaches, including whole-lake manipulations, in situ enclosure/exclosure experiments, pond experiments, theoretical modeling, laboratory experiments, and descriptive sampling. In particular I am interested in:
