I am retired and my research and that of my former graduate students and post-docs (Entomology and Ecology) included research in several areas of stream ecology, such as: evaluating the effects of various land use practices on stream ecosystems; effects of watershed, food and nutrient manipulations on stream ecosystems; and, effects of anthropogenic disturbances, stream size gradients, and local geomorphology on invertebrate community structure and secondary production. Our studies also included: the long-term manipulation of stream resource bases (terrestrial litter inputs) to assess linkages between streams and adjacent forests with aquatic invertebrate community structure and production; effects of invertebrates on processing terrestrial inputs and long-term dynamics of particulate organic and inorganic export from headwater streams (with Drs. S. Eggert, J. L. Meyer and J. R. Webster); and, effects of nutrient enrichment of headwater streams on ecosystem processes, including secondary production (with Dr. A. Rosemond, et al.).
