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.

Salinity, Flooding, and Urban Impacts to Critical Habitat of the Endangered Red-cockaded Woodpecker

USGS researchers will collect data on salinity, water level, and flooding duration within Big Branch National Wildlife Refuge to improve the understanding of the hydrologic system, and how hydrology drives available red-cockaded woodpecker habitat use and availability across the landscape.

Population Monitoring of the Federally Threatened Okaloosa Darter at Eglin Air Force Base

USGS' and Loyola University New Orleans' innovative research techniques played a role in the decision to downlist the Okaloosa Darter, a freshwater fish endemic to northwest Florida, from Endangered to Threatened in 2011, and the removal of the fish from the U.S. Endangered Species Act in 2023.

Development and Implementation of Environmental DNA (eDNA) Tools to Aid Listing and Recovery Efforts for Imperiled and Common Freshwater Mussels

Researchers will develop and optimize an eDNA assay to delineate the current distribution of P. inflatus . The assay will then be used to provide up-to-date distributional information and detection rates for P. inflatus in the Pearl River basin.
