Species Stressors

White-nose syndrome has killed more than five million bats since its discovery in 2006. USGS is developing a non-invasive and user-friendly CRISPR white-nose syndrome biosensor to allow for quick detection of the pathogen that causes the disease.

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.

WARC Researchers are comparing tree and root growth, soil CO2 flux, and surface elevation change between fertilized and unfertilized mangrove forests to assess the potential impact of increased nutrient loading and to help rate mangrove stand vulnerability.

USGS scientists will be analyzing weather surveillance radar observations of birds departing stopover habitats to measure responses to climate change.

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.

WARC researchers are gathering amphibian data to better understand the impact of natural disasters on treefrog populations and examine post-event processes.

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...

USGS researchers are working with partners to assess the health and foraging behavior of Florida manatees in the northern Indian River Lagoon and Banana River, areas that have experienced declining seagrasses due to an extended phytoplankton bloom.

USGS is working with partners to understand how the federally protected Florida manatee population changes over time and responds to threats.

Collisons between wildlife and vehicles threaten many species, and can lead to human loss of life, injuries, and loss of property. USGS is developing models to help evaluate the effectiveness of wildlife protection zones and optimize the design of these protected areas.

Pink-footed geese in Svalbard are a highly valued resource, but their increasing population causes conflicts with agricultural needs. USGS is devloping population models to help inform management of optimal harvest strategies.

The Florida apple snail is a critical component of the state's wetland food webs. USGS scientists assess the effects of native and non-native fishes on the native snail populations.
