To inform conservation efforts for the Gulf Coast, USGS is developing a suite of decision support tools to provide explicit population and habitat objectives.
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.
Alabama Strategic Habitat Unit (SHU)
Alabama is host to a variety of freshwater species, many of which are critically imperiled. USGS and partners focus conservation activities in high priority watersheds throughout the state.
Using Environmental DNA for Burmese Python Detection Probabilities and Range-Delimitation in Southern Florida
Current tools for detection of Burmese pythons in South Florida have resulted in low detection rates. Environmental DNA - eDNA - has shown to be effective at detecting these invasive snakes, and can help to determine range limits for the species, information that is critical for management and control efforts.
Wetland Evaluation and Sediment Elevation Monitoring and Analysis in the Indian River Lagoon
To better understand coastal response to sea-level rise, USGS is monitoring coastal wetland sediment elevations along Florida's east coast.
Life on the Edge: Can Corals Thriving in Mangroves Provide Insights into Climate Change?
On an island in the U.S. Virgin Islands, USGS scientists discover corals are seeking refuge from climate change in mangroves.

Triangle area water supply monitoring project, North Carolina-Summary of monitoring activities, quality assurance, and data, October 2015–September 2017
Surface-water supplies are important sources of drinking water for residents in the Triangle area of North Carolina, which is located within the upper Cape Fear and Neuse River Basins. Since 1988, the U.S. Geological Survey and a consortium of local governments have tracked water-quality conditions and trends in several of the area’s water-supply...
Pfeifle, C.A.; Cain, J.L.; Rasmussen, R.B. Environmental DNA assays for invasive populations of the Black Carp, Mylopharyngodon piceus, in North America
The Black Carp, Mylopharyngodon piceus, is an increasingly widespread invasive species in North America that threatens freshwater mussel populations. We developed four qPCR assays for detecting environmental DNA (eDNA) from these Black Carp populations. Assays were designed to target four mitochondrial DNA loci and were based on 34 complete...

Integrative taxonomy reveals a new species of freshwater mussel, Potamilus streckersoni sp. nov. (Bivalvia: Unionidae): Implications for conservation and management
Inaccurate systematics confound our ability to determine evolutionary processes that have led to the diversification of many taxa. The North American freshwater mussel tribe Lampsilini is one of the better-studied groups in Unionidae, however, many supraspecific relationships between lampsiline genera remain unresolved. Two genera previously...
Smith, Chase H.; Johnson, Nathan; Inoue, Kentaro; Doyle, Robert; Randklev, Charles R. Cell-Based metabolomics for untargeted screening and prioritization of vertebrate-active stressors in streams across the United States
The U.S. Geological Survey and the U.S. Environmental Protection Agency have assessed contaminants in 38 streams across the U.S., using an extensive suite of target-chemical analysis methods along with a variety of biological effects tools. Here we report zebrafish liver (ZFL) cell-culture based NMR metabolomic analysis of these split stream...
Collette, Timothy W.; Ekman, Drew R.; Zhen, Huajun; Nguyen, Ha; Bradley, Paul; Teng, Quincy Perspective: Developing flow policies to balance the water needs of humans and wetlands requires a landscape scale approach inclusive of future scenarios and multiple timescales
Maintenance of the natural flow regime is essential for continued wetland integrity; however, the flow regime is greatly influenced by both natural and anthropogenic forces. Wetlands may be particularly susceptible to altered flow regimes as they are directly impacted by water flows at a variety of time scales. In Puerto Rico, contemporary water...
Murry, Brent; Bowden, Jared; Branoff, Benjamin; Garcia-Bermudez, Miguel; Middleton, Beth; Ortiz-Zayas, Jorge; Restrepo, Carla; Terando, Adam The relationship of channel planform and point bar architecture on a reach of the Wabash River near Grayville, Illinois
The erosional and depositional characteristics of meandering rivers lead to the formation and maintenance of point bars along the inner banks of meander bends. Point bars are composed of sediment layers in patterns resulting from the rate and style of channel migration, hydrodynamics, and sediment transport and deposition within the river system (...
Rowley, Taylor; Konsoer, Kory; Ursic, Mick; Langendoen, Eddy J. Channel modification and evolution alter hydraulic connectivity in the Atchafalaya River basin increasing vulnerability to sea-level rise
Channel dredging and erosion in the Atchafalaya River basin have resulted in changes to the hydraulic connectivity of this floodplain swamp that have not been previously quantified. In this study, analyses were conducted to determine hydraulic and geomorphic factors that have changed since channel closure in 1962. Results indicated changes...
Kroes, Daniel; Day, Richard H.; Demas, Charles R.; Allen, Yvonne C.; Roberts, Steve Combining numerical and statistical models to predict storm-induced dune erosion
Dune erosion is an important aspect to consider when assessing coastal flood risk, as dune elevation loss makes the protected areas more susceptible to flooding. However, most advanced dune erosion numerical models are computationally expensive, which hinders their application in early-warning systems. Based on a combination of probabilistic and...

Hurricanes brush or hit Charleston, S.C., about once every five and a half years, often generating large storm surges on top of already impressive tides. A hurricane that hit Charleston in 1752 caused a storm surge that nearly covered the entire present downtown area, according to one source. When the wind shifted, the water level fell 5 feet in 10 minutes.

Coal provides more than half of our Nation’s electrical energy needs. For more than three centuries, coal has been mined in the Appalachian Basin, one of the most important coal producing regions in the world. This area includes parts of Ohio, Pennsylvania, West Virginia, Kentucky, Virginia, Maryland, and Tennessee. Almost all of the coal now mined in the Appalachian Basin is used in eastern state

Using a time-tested technique in a new way, scientists at the U.S. Geological Survey (USGS) have been able to determine how quickly marine groundwater has encroached into South Florida?s inland fresh water aquifers.
Evidence recently obtained by scientists at the U.S. Geological Survey (USGS) indicates that an ancient sand delta in South Florida, discovered in 1999 by scientists from the USGS and the University of South Florida, rivals the size of deltaic lobes of the modern-day Mississippi River.
Recent evidence recovered from the muddy bottom of Florida Bay by a team of USGS scientists indicates that some of the changes in Florida Bay’s ecosystem are natural and some are not. Lynn Brewster-Wingard will present data from cores that show a significant increase in the last 20-40 years in Brachidontes exustus, a mussel that is tolerant of poor water quality and a wide range of salinities.
