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.
Avifauna Surveys of the Northern Main Chandeleur Islands
USGS WARC ecologists are assisting partners in conducting avian surveys on Chandeleur Islands during the pre-restoration monitoring phase to document threatened and endangered species, species richness and diversity, species abundance, and habitat use.
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.
Sturgeon Occurrence and Behavior in the Outer Continental Shelf
A new study aims to collect information on sturgeon temporal and spatial distribution to inform offshore wind energy and sand leasing operations.
Demographic Analysis of the Endangered Cape Sable Seaside Sparrow
USGS researchers will examine how hydrology and landscape vegetation changes impact Cape Sable Seaside Sparrow survival and population growth.
Natural Resource Damage and Assessment (NRDA) Program-Louisiana’s Monitoring and Adaptive Management
The USGS is participating in the Louisiana-Trustee Implementation Group Monitoring and Adaptive Management work group to assess the injuries caused by the Deepwater Horizon oil spill and to select the appropriate restoration measures to compensate the public for the injury to coastal and marine resources.
Seasonal Surveys of Shorebird and Coastal Waterbird Utilization of Dredged Material Islands in the Baptiste Collette Bayou, U.S. Army Corps of Engineers (USACE) New Orleans District, Louisiana
To assess use of dredge material areas, avian ecologists from USGS WARC are conducting bird surveys across the annual life cycle.
Strategic Habitat Conservation for Gulf Sturgeon
WARC researchers partnered with Gulf Sturgeon decision makers and biologists to develop a Bayesian network model that uses habitat characteristics to predict the quantity of juvenile winter foraging habitat under alternative river discharge and timing of juvenile arrival scenarios.
Strategic Habitat Conservation for Beach Mice (Peromyscus polionotus ssp.)
WARC researchers partnered with beach mice managers and biologists to estimate habitat objectives and the amount of effort needed to achieve the habitat objective (i.e., management efficiency) for three beach mice subspecies in Florida’s panhandle.
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.
Quantitative Tools for the Urgent Recovery and Regulatory Needs of the Florida Bonneted Bat, Eumops floridanus
WARC researchers are organizing Florida bonneted bat echolocation recordings into a database to assess population trends and bat response to management actions.
