Coral Bleaching and Disease: Effects on Threatened Corals and Reefs

Severe coral bleaching in 2005, followed by a disease outbreak, resulted in severe reef degradation in the US Virgin Islands; the amount of living coral cover at long-term monitoring sites decreased an average of 60%. With climate change, high seawater temperatures are expected to lead to more frequent bleaching episodes and possibly more disease outbreaks.

Mangrove Migration Network

At the poleward marsh-mangrove ecotone, mangrove abundance and coverage is winter temperature-sensitive in that it oscillates in response to the frequency, duration, and/or intensity of extreme winter temperatures. Future winter climate change is expected to facilitate poleward mangrove range expansion at the expense of salt marshes in Texas, Louisiana, and parts of Florida.

Watershed Controls of Freshwater Wetland Nutrient Stoichiometry and Sensitivity to Eutrophication

When it comes to freshwater wetlands, hydrology plays a large role in nutrient stoichiometry and sensitivity to nutrient inputs. Although wetland biogeochemists intuitively understand these important relationships between landscape position, hydrology, and sensitivity to nutrient inputs, these relationships have never been quantified using geospatial data. The objective of this project will be...
