Current research and/or projects
Contributing to improved understanding of land-use change and other human disturbances on aquatic, wetland and riparian ecosystems
- Cycling of carbon and nitrogen in aquatic and wetland ecosystems and their role in the sequestration of atmospheric carbon.
- Influence of agricultural practices on greenhouse gas exchange at adjacent wetlands and riparian zones
- Carbon, nitrogen and greenhouse gas dynamics in forested wetlands
- Interactions among carbon and metal cycles, microbial ecology, human impacts and climate change effects on the Lake Erie ecosystem
- Dissolved organic matter, its role in aquatic and wetland ecosystems, and modification by microbial and photochemical processes
