Trends in organic matter in baldcypress swamps of the southeastern United States: 2007-2011

A better understanding of the potential of climate change to affect carbon dynamics in wetlands can be gained through the study of plant decomposition and soil organic matter trends across continental gradients. This study from 2007 and 2011 examines patterns of wood, leaf and cloth decomposition, as well as soil organic matter storage in Taxodium distichum (T. distichum) swamps along the Mississippi River Alluvial Valley (MRAV) and the northern Gulf of Mexico (GOM) in North America.
