Imperiled Species

Generally speaking, imperiled species are those animals and plants that are in decline and may be in danger of extinction. While some species are federally protected under the Endangered Species Act, many species are not due to the lack of knowledge regarding their status and the environmental factors that may threaten their future.

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.

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.
