Ecophysiology

The U.S. Geological Survey Amphibian Research Monitoring Initiative (ARMI) is using a combination of swabbing, non-lethal tissue sampling, soil and water sampling, and collection of a variety of other environmental variables to determine the relationships between the prevalence and pathogen load of Bd infection and environmental stressors on green treefrog survival.

The Hunt For The Southernmost Snakehead. Thirty-one fishery biologists from eleven agencies participated in a two-day Fish Slam event. Thirty-five sites in Broward and Miami-Dade counties were sampled for non-native fishes.

22-23 March 2017 - Ten teams of fishery biologists sampled 28 sites amid unexpected wildfires in the Big Cypress National Preserve over the two day period. On the second day a reporter from the Miami Herald accompanied a ground crew team.

The Florida Non-Native Fish Action Alliance brings together federal and state agencies, academic institutions, and non-governmental organizations to address the need for documenting and managing the non-native fishes introduced to the state's waters.

November 1 - 2, 2016 – Eight teams of fishery biologists from the US Geological Survey (USGS), US Fish and Wildlife Service - Peninsular Florida Fisheries Office and Welaka National Fish Hatchery (USFWS), the National Park Service (NPS), Florida Fish and Wildlife Conservation Commission (FWC), Florida International University (FIU), and Zoo Miami sampled 20 sites for non-native fishes in Palm...

May 23, 2016 – Five teams of fishery biologists from the U.S. Geological Survey (USGS), Florida Fish and Wildlife Conservation Commission (FWC), the National Park Service (NPS), Florida Museum of Natural History (FLMNH), University of Florida (UF), and Florida International University (FIU) sampled 12 sites for non-native fishes in Broward and Miami-Dade counties in southeastern Florida.

Many aspects of lionfish biology are studied at the USGS Wetland and Aquatic Research Center. As part of the U.S. Geological Survey Nonindigenous Aquatic Species database, the distribution of lionfish is tracked over time.

The Florida Everglades is the largest wetland ecosystem in the United States and supports a diverse flora and fauna, including many rare species.

In this project, USGS scientists are developing a new genetic technique – Trojan Y – to help eradicate invasive species. Although the methodology has been well-developed in theory, this is the first test of its practical application.

To control or possibly eliminate non-native species without harm to native fauna, a genetic technique using sex-reversed females with two Y chromosomes (Trojan Y) is being developed to reduce the breeding success of the species, ultimately resulting in population decline or loss.

Welcome to the Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey. Located at Gainesville, Florida, this site has been established as a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, distribution maps, and general...

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.
