Population dynamics and ecological interactions of aquatic microorganisms.
Effects of the light and chemical environment on aquatic microbial community structure and function.
Nutrient biogeochemistry in aquatic and terrestrial ecosystems.
Our lab is
various studies in the areas of aquatic ecology and biogeochemistry. Broadly speaking, we are
connections between the abiotic environment, plankton community
activities, and biogeochemical cycles involving nitrogen, phosphorus,
research is focused mostly
on aquatic habitats of northern Mississippi including oxbow lakes,
wetland types, reservoirs, the Mississippi River itself, and even flooded agricultural fields in the
Mississippi Delta. Funding
our work comes primarily from the National Science Foundation, the
Environmental Protection Agency, and the Department of Agriculture.
