Geographical Trends in Ecosystem Function and Biodiversity of Wetlands as a Surrogate for Climate Change

Extreme drought and temperature in the southeastern United States may become more frequent in the future, and any  extreme shifts in climate condition are likely to have effects on wetland ecosystem function. USGS research predicts the effects of climate change by shifts in function and biodiversity across existing  climate gradients in baldcypress swamps.
