Beth A Middleton, Ph. D.
Beth Middleton is a Research Ecologist at the USGS Wetland and Aquatic Research Center.
Wetland function may be altered in the future because of dynamic shifts in droughts, water extraction, water fluctuation, salinity intrusion, CO2 levels, and storm intensity. Populations of species can be extirpated especially by drought, and tree mortality is especially common at the edges of species diestribution ranges during drought. Beth Middleton examines patterns of ecosystem function along latitudinal gradients in baldcypress swamps, monsoonal wetlands, mangrove swamps, northern peatleands, prairie fens, and floodplain wetlands. She has organized symposia, written three books, and edited three special journal volumes, which support multidisciplinary comparisons and research analysis of wetland function. Other research topics include the effects of hurricanes on coastal wetlands, flood pulsing in restoration, and biodiversity loss in fens of Europe, Asia and North America. Middleton maintains a research network of baldcypress swamps (North American Baldcypress Swamp Network) and invites other researchers to work in these study sites dedicated to the study of long term function of swamps in the southeastern US.

Practical guide to measuring wetland carbon pools and fluxes
Wetlands cover a small portion of the world, but have disproportionate influence on global carbon (C) sequestration, carbon dioxide and methane emissions, and aquatic C fluxes. However, the underlying biogeochemical processes that affect wetland C pools and fluxes are complex and dynamic, making measurements of wetland C challenging. Over decades of research, many observational, experimental, and
