My laboratory is currently working in the biogeochemistry of agricultural streams and wetlands. We have recently examined the response of stream water quality to modified watershed management practices and and riparian restoration. While examining the response of water quality we have also examined the response of periphyton, invertebrates and fishes in these streams. The research in these systems in currently being studied by Brian Grebliunas and he is focusing on denitrification in constructed wetlands. This work is being done at the Lexington Demonstration Farm just west of Lexington IL.
