Development of Environmental DNA (eDNA) Detection Tools to Track the Obligate Coral Predator Coralliophila galea to Support Coral Outplant Site Selection

With the support of the Mote Marine Laboratory and Aquarium, USGS researchers will develop and optimize a CRISPR biosensor to detect C. galea eDNA in the field. The development of this tool could assist coral restoration managers and stakeholders to more effectively inform decisions on coral outplant site selection, based on coral predator presence.

A Rapid CRISPR-based Field Test for the Non-invasive Detection of the Fungal Causative Agent of White-nose Syndrome

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.

Post-Hurricane Florence Sea Turtle Nesting Habitat Nest Site Selection at Cape Hatteras and Cape Lookout National Seashores

WARC researchers will be surveying nesting beaches in Cape Hatteras and Cape Lookout National Seashores. They will record GPS locations for all crawls, nests, and turtles encountered/captured, and will be placing satellite tags on a subset of individuals to determine habitat use and delineate inter-nesting areas used by reproductive females.

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.

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...
