Trees a Surprisingly Large Source of Methane [article]
The Biogeochemistry Lab studies element cycles to understand how ecosystems respond to global-scale changes such as sea level rise, warming, elevated carbon dioxide, nitrogen pollution and invasive species.
Our holistic approach integrates the responses of both plants and microbes, the two dominant life forms regulating the capture and release of energy in organic compounds.
We operate the Smithsonian's Global Change Research Wetland, and NSF-LTREB facility dedicated to unraveling the complex ecological processes that confer stability on coastal marshes as they respond to global environmental change. Other research themes include methane emissions from wetlands and upland forests, and carbon sequestration in blue carbon ecosystems.
SERC and international collaborators publish on wetland carbon storage in Nature
The Biogeochemistry lab's Patrick Megonigal and James Holmquist were co-authors on a recent global synthesis of carbon storage in coastal wetlands. They demonstrate that wetlands experiencing rapid sea level rise store more carbon than wetlands under stable sea level conditions, suggesting a mitigation effect coastal wetlands have on global environmental change.
