Aerial Videography Overflights of Forest Cover and Impact from Hurricane Sandy along the Atlantic Coast, USA
High resolution imagery (aerial videography) was obtained of Hurricane Sandy to assess forest damage by documenting disturbed canopy and downed trees.
Hurricane Sandy Surge and Marsh Dieback in the New Jersey Coastal Zone
Detection of storm surge impacts on coastal marshes requires regional or broader mapping of surge flooding above and below the wetland canopy and estimation of abnormal change in wetland condition.
Joint Research on Water and Sedimentation Changes and Potential Impacts on Biodiversity along the Porsuk River, Turkey
The Porsuk River floodplain near Eskisehir, Turkey contains a large number of wetlands, which have been managed by humans for millennia.
Long-term Trends in Swamp Tree Growth across Drought and Salinity Gradients along the Northern Gulf Coast
This study will examine the potential effects of climate-change-induced sea level rise, drought and water extraction by examining tree growth patterns across the Gulf Coast, specifically targeting long-term research plots available in the North American Baldcypress Swamp Network (NABCSN) and the Suwannee River.
Mangroves vs. Salt Marshes: Mangrove Forest Range Expansion at the Expense of Salt Marshes
Winter climate change has the potential to have a large impact on coastal wetlands in the southeastern United States.
Climate Envelope Modeling for Evaluating Anticipated Effects of Climate Change on Threatened and Endangered Species
Modeling both potential changes in climate and responses of species and habitats can increase certainty in management decisions by helping managers to understand the range of possible species and habitat responses under different alternative futures. Climate envelope modeling is one type of modeling that can be useful in understanding species and habitat responses to climate change because it...
Peninsular Florida Landscape Conservation Cooperative (PFLCC) Climate Scenarios and Species Vulnerability Assessment
Peninsular Florida is one of the most vulnerable regions to climate change in the United States. With complex socioeconomic and ecology dynamics and a large number of governing agencies involved in conservation planning, USGS worked to created an appropriate framework for landscape conservation cooperative-scale decision-making across current conservation planning agencies and jurisdictions.
Coral Bleaching and Disease: Effects on Threatened Corals and Reefs
A severe disease - tentatively named stony coral tissue loss disease - is rapidly killing corals in the U.S. Virgin Islands. Scientists from the U.S. Geological Survey, the University of Puerto Rico, and the National Park Service are working together to better under the disease and determine if the disease affecting corals in the USVI is the same one that has been killing corals in Florida since...
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.
Incorporating Future Change into Current Conservation Planning: Evaluating Wetland Migration along the Gulf of Mexico under Alternative Sea-Level Rise and Urbanization Scenarios
More than half of contiguous U.S. coastal wetlands are located along the Gulf of Mexico coast. These highly-productive wetlands support many ecosystem goods and services and fish and wildlife habitat. Historically, coastal wetlands have adapted to sea-level changes via lateral and vertical movement on the landscape. As sea levels rise in the future, coastal wetlands will adapt and migrate landward...
Macroclimatic Controls of Coastal Wetland Ecosystem Structure and Function
At the global-scale, macroclimatic drivers govern ecosystem structure and function in tidal saline wetlands (e.g., salt marshes, mangrove forests, salt flats). However, global reviews and models for these ecosystems typically do not directly include climatic drivers. The objective of this research is to examine and forecast the effects of macroclimatic drivers on wetland ecosystem structure and...
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.
