Research interests
My primary research interests focus on community to ecosystem level aspects of streams and riverine wetlands, especially low-gradient blackwater streams and their floodplains.  Much of my work has involved aspects of habitat utilization, resource partitioning, spatial and temporal patterns of invertebrate abundance, and the trophic and production ecology of aquatic invertebrates.  My work also examines linkages between invertebrates and detritus dynamics in stream channels with those in fringing floodplains. Other research efforts include analysis of community structure in vernal pools, the effects of changing land use patterns on the biological structure of streams, and bioassessment methodology.
