Ecosystem Ecology Group

800 532 Stroud Water Research Center

About the Group

The Ecosystem Ecology Group focuses on interactions among physical, chemical, and biological elements of riverine ecosystems that organize ecological behavior at local and regional scales. We are also interested in the effects of global change (land use, atmospheric deposition, emergent contaminants) on the structure and function of streams and rivers, and the need for more socio-ecological perspectives on conservation and restoration of running water ecosystems.
