The Skidmore Biogeochemistry Laboratory focuses on terrestrial ecosystem ecology and biogeochemistry with a focus global environmental change impacts on forest, wetland, and aquatic ecosystems. We are particularly interested in how below-ground microbial processes mediate productivity and carbon and nutrient cycling patterns at the local to global scale. Students in the lab learn techniques for measuring biogeochemical process rates and quantifying ecosystem properties across varying spatial and temporal scales. Some specific research areas in which students are involved are:
- Forest carbon and nutrient cycling in response to atmospheric deposition
- Terrestrial controls on nutrient transport to surface waters and aquatic ecosystems
- Microbial controls on the production and emission of greenhouse gases from soils and sediments
- Plant traits and soil microbial community composition as drivers of ecosystem nutrient cycling and organic matter dynamics
