Ecological Stressors
Ecological Stressors
USGS WARC scientists study environmental and anthropogenic (human-caused) stressors, such as hurricanes and climate change, that potentially impact the health and productivity of lands and waters of management concern.

Mesophotic and Deep Benthic Communities: Coral Propagation Technique (CPT) Development Project
Through a collaborative effort with other federal agencies and academic and research institutions, the USGS is working to inform and enhance the protection and management of coral communities in mesophotic and deep benthic areas of the Gulf of Mexico.
Beach Compaction and the Impacts of Tilling on Nesting Sea Turtles and Foraging Shorebirds
Researchers are investigating beach compaction, the incubation environment for turtle nests, and shorebird nest abundance at beaches throughout the southeastern United States to better understand the impacts of beach compaction to nesting turtles and foraging seabirds.
Puget Sound Marine Benthic Index and Graphical Causal Model
USGS scientists are working with partners at the Puget Sound Partnership and the State of Washington’s Department of Ecology to develop two new tools to help us understand how human disturbance affects life at the top of Puget Sound: a Marine Benthic Index and a graphical causal model.
Integrating Science and Management to Assist with the Response to Stony Coral Tissue Loss Disease
A USGS multi-disciplinary team will use laboratory and modeling approaches to investigate the cause of stony coral tissue loss disease.
Integrating Sea Level Rise Scenarios into Everglades Restoration Planning
One of the largest and most expensive restoration efforts in the world is the restoration of the Everglades, a sub-tropical freshwater wetland system located in southern Florida. This unique ecosystem supports several endemic and endangered species, provides flood control for Florida’s large urban population, and provides water for both the agricultural and drinking supply within the state. The Co
Detecting Sublethal Effects of Harmful Algal Blooms in Mammalian and Avian Cells
USGS Researchers are collaborating to study avian and mammalian cells to detect sublethal toxin effects following exposure to harmful algal blooms.
Adapting to Climate Change: Trends and Severe Storm Responses by Migratory Landbirds and Their Habitats
USGS scientists will be analyzing weather surveillance radar observations of birds departing stopover habitats to measure responses to climate change.
Using Occupancy Analysis to Understand Ecological and Environmental Stressors that Affect the Range and Abundance of Gulf Coast Waterdogs (Necturus beyeri) in Louisiana Bayous
Sampling for Gulf Coast waterdogs is providing essential information to better understand the factors that impact the species' occupancy across Louisiana.
Interaction of Environmental Stressors and Batrachochytrium dendrobatidis (Bd) Pathogen Loads on Survival of Green Frogs (Lithobates clamitans)
The U.S. Geological Survey Amphibian Research Monitoring Initiative (ARMI) is using a combination of swabbing, non-lethal tissue sampling, soil and water sampling, and collection of a variety of other environmental variables to determine the relationships between the prevalence and pathogen load of Bd infection and environmental stressors on green treefrog survival.
Capture-Mark-Recapture of Treefrogs at Bayou Teche National Wildlife Refuge
WARC researchers are gathering amphibian data to better understand the impact of natural disasters on treefrog populations and examine post-event processes.
Impacts of coastal and watershed changes on upper estuaries: causes and implications of wetland ecosystem transitions along the US Atlantic and Gulf Coasts
Estuaries and their surrounding wetlands are coastal transition zones where freshwater rivers meet tidal seawater. As sea levels rise, tidal forces move saltier water farther upstream, extending into freshwater wetland areas. Human changes to the surrounding landscape may amplify the effects of this tidal extension, impacting the resiliency and function of the upper estuarine wetlands. One visible...
Contaminants Assessment in the Coral Reefs of the Virgin Islands National Park and Virgin Islands Coral Reef National Monument
USGS collected samples at reef locations within the Virgin Islands National Park and analyzed for the presence of contaminants, organotin compounds, or sunscreen compounds.
