Research

The fundamental focus of discovery in the Frimpong Lab is how fish species’ traits interact with environmental and habitat factors to determine local and landscape-wide distribution and abundances. Pursuing this research focus leads to observational and experimental field and laboratory studies of the ecology of particular fish species and entire fish communities (e.g., bluehead chubs and their nest associates in tributaries of the New, Roanoke, and James River basins), and systematic documentation and synthesis of traits and distributions of freshwater fishes. He tackles ecological hypotheses at varying spatial and temporal scales, as required by the broad-ranging societal problems that ecology contributes to solving. Dr. Frimpong’s training is grounded in multiple basic and applied disciplines and he enjoys confronting research problems that draw on at least one of these disciplines and necessitates interdisciplinary approaches and local, national, and international collaborations.

He pursues fundamental ecological research to further a complementary applied research and teaching program in biological assessment, aquatic conservation and resource management, sustainable aquaculture development, and natural resources policy analysis. The diversity of backgrounds and research foci among the Frimpong Lab students reflect the range of contemporary environmental and natural resources management issues the lab is researching and engaged in with decision makers. These issues include land uses and landscape transformations, aquatic habitat degradation, resource overexploitation, nonnative species transplantations, and climate change. Dr. Frimpong employs quantitative methods (GIS, statistics, various economic analysis tools) extensively in research and teaching. The Frimpong Lab espouses the philosophy that data are expensive and precious, and therefore should be diligently preserved and shared, and that rigorous quantitative analyses of data undergird defensible science, management, and policy.
