WARC SSP Goal 1

This website provides access to the list of crayfish in Canada and the United States as determined by the 2007 American Fisheries Society (AFS) Endangered Species Committee (ESC) on Crayfishes.

As part of the Comprehensive Everglades Restoration Plan, water managers are planning to use treated wastewater from the South District Wastewater Treatment Plant (WWTP) to supplement the canal waters that will be used to rehydrate wetlands adjacent to the Biscayne National Park (Park).

The largemouth bass is a highly managed sport fish. Detailed genetic information on the fish at the gene level can provide researchers insight into genomic control of phenotypic expression of life-history traits, core physiological functions, and other aspects of biology.

Understanding amphibian's life-histories can help predict how they may persist in aquatic habitats in the face of droughts and other climate change-associated events.

Peninsular Florida has a high density of species and ecosystems of conservation concern, as well as many threats to the persistence of native species and their habitats. USGS worked closely with the Peninsular Florida Landscape Conservation Cooperative to define conservation targets to help meet conservation goals.

Peninsular Florida is one of the most vulnerable regions to climate change in the United States. With complex socioeconomic and ecology dynamics and a large number of governing agencies involved in conservation planning, USGS worked to created an appropriate framework for landscape conservation cooperative-scale decision-making across current conservation planning agencies and jurisdictions.

Freshwater mussels are considered the most imperiled group of animals in the United States. These animals provide valuable ecological services by filtering water, sequestering nutrients, and providing forage for migratory birds, small mammals, and turtles. They also have a unique and complex life cycle that makes them especially vulnerable to human disturbances. It includes a parasitic larval...

The Conasauga River in northwest Georgia and southeast Tennessee harbors the majority of mussel diversity still found in the Georgia portion of the Upper Coosa Basin. While the Conasauga historically supported at least 44 mussel species, only about 20 species remain.

Dauphin Island, Alabama, is the only barrier island providing protection to much of Alabama's coastal natural resources. Severely impacted by repeated extreme events, like Hurricane Katrina and Deepwater Horizon oil spill, USGS and partners are conducting a joint study to evaluate the feasibility of certain alternatives to increase resiliency and sustainability of the island.

USGS aims to integrate biological and hydrological models to help develop management tools to deal with the projected ecological consequences of rising sea level in coastal south Florida.

The invasive grass carp and black carp are artificially spawned to produce triploids, which means they have three sets of chromosomes and are sterile. WARC scientists invented an early ploidy prediction process for produced fry, and a post-mortem assessment method for carp caught either in the wild or sold and hauled live to other states.

The MC252 oil spill introduced hydrocarbons, dispersants, and drilling muds into the Gulf of Mexico, potentially adversely affecting the seafloor environment surrounding the spill site.
