Dr. Bruce Wallace

My research is in stream ecology and involves work in several areas. These areas include: effects of disturbance on stream ecosystems; organic matter dynamics in streams; secondary production and ecology of aquatic invertebrates; manipulation of stream food webs; invertebrate community structure in streams; and, role of aquatic invertebrates in stream ecosystem processes. Most of my current research centers on projects at the Coweeta Hydrological Laboratory in the Appalachian Mountains of western North Carolina. Our work has centered around several major themes that include: 1) secondary production of invertebrates and factors influencing their production; 2) the influence of watershed disturbance on stream communities; 3) long-term dynamics of particulate export from streams; 4) manipulation of stream resource bases (terrestrial litter inputs) to assess linkages between streams and the watersheds they drain (with Dr. J. L. Meyer et al.); and, 5) the effects of nutrient enrichment on a headwater stream (with Dr. Amy Rosemond et al.). At present my work and that of my graduate students (Entomology and Ecology) includes studies evaluating the effects of various land use practices, including watershed, food and nutrient manipulations, anthropogenic disturbances, stream size gradients, and local geomorphology on invertebrate community structure and production.
