The Biogeochemistry Lab studies element cycling to better understand how ecosystems respond to global changes, such as sea-level rise, nitrogen pollution, invasive species and elevated CO2.
We take a holistic approach to these issues by integrating the responses of both plants and microbes, the two dominant life forms regulating the capture and release of energy in organic compounds.
We also operate the Smithsonian's Global Change Research Wetland. The NSF-LTREB tidal marsh has operated since 1985 and is home to three long-term field manipulations of key global change factors. Major research themes include the stability of tidal wetlands to sea-level rise, regulation of methane emissions from wetlands and upland forests, and carbon sequestration in blue carbon ecosystems.
