Life History Characterization and Host Fish Identification for Federally Listed and Imperiled Freshwater Mussel Species in the Suwannee River Basin in Georgia and Florida
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...
Evaluation of Stream Reaches for Mussel Reintroduction in the Upper Coosa Watershed, NW Georgia
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.
Stress Physiology, Scaling, and Water Use of Forested Wetland Trees and Stands
USGS investigates the eco-physiological responses of coastal forested wetland vegetation to envrionmental stressors, and what role vegetation may have in affecting local hydrological cycling as a result of these stressors.
Modeling Tidal Freshwater Forested Wetlands (TFFW) Habitat Changes for Land Management
As tidal freshwater forested wetlands - TFFWs - are influenced by salinty due to salt water intrusion, they may experience changes in plant community composition, growth, and productivity. Models are needed to predict vegetation community change or dieback, as well as changes in carbon sequestration and storage due to changing climate, drought, changes in freshwater discharge, elevated carbon...
Ecology of Tidal Freshwater Forested Wetlands of the Southeastern United States
Tidal freshwater forested wetlands - TFFWs - can be found in the upper intertidal areas of many estuaries and act as a transition between coastal marshes and bottomland hardwood wetlands. However, it is because of their location that makes them vulnerable to sea-level rise, and they are constantly transitioning to different wetland types. USGS addresses how various processes are affected in TFFWs...
Integrative Studies of Florida Spring Ecosystems
Florida's springs are a source of cultural, recreational, and ecological importance. But land-use changes and increased demands for groundwater due to the state's growing population have led to widespread impairment of these unique ecosystems.
