Species Biology
Species Biology
USGS WARC science plays a critical role in informing listing decisions related to the Endangered Species Act. Our work provides insight into the life history, population dynamics, and resource needs of species considered at risk or of management concern, including aquatic mammals, reptiles, amphibians, birds, bats, and fishes.

Adaptive Management for the Northern Bobwhite on the Babcock-Webb Wildlife Management Area
Based on field research conducted during 2002-2009, the bobwhite population on the Babcock-Webb Wildlife Management Area (WMA) in Southwest Florida is incapable of supporting desired levels of sport harvest.
Use of Amphibian Communities as Indicators of Restoration Success in the Greater Everglades
Habitat alteration and climate, when combined, are serious threats to amphibians and other wildlife. Habitat suitability models are being used to predict the responses of an amphibian community to hydrological and habitat restoration in the Greater Everglades Ecosystem.
Assessment of South Atlantic Landscape Conservation Cooperative (SALCC) Marine Indicators
The South Atlantic Landscape Conservation Cooperative (SALCC) has proposed natural resource indicators and associated targets for the marine ecosystem.
A Bibliography of All Known Publications & Reports on the Gulf Sturgeon Acipenser oxyrinchus desotoi (through 31 December 2013)
This functional bibliography is meant to be a complete and comprehensive bibliography of all discoverable reports containing information on the Gulf Sturgeon (GS). This bibliography contains all known reports presenting, documenting, summarizing, listing, or interpreting information on the GS through 31 December 2013.
Coping with Invasive Alien Species and Environmental Stressors: Linking Behavioral Studies with Management for Anuran Amphibians
Climate change and invasive species are two key drivers of biodiversity loss. Knowing how amphibians respond to climate change and invasive species can greatly improve predictions of species' persistence in the face of these factors and can help guide resource managers and conservation biologists in developing strategies to manage for these encroaching disturbances.
Systematic Studies of Southeastern Fishes
The southeastern United States is home to a variety of freshwater snails, mussels, crayfish, and fishes. USGS scientists are conducting systematic studies to better document the region's biodiversity.
Conservation Research on North American Freshwater Faunas
The decline of freshwater animals has resulted in an increase in the number of imperiled species and extinctions. USGS scientists use genetics to determine if these species truly are gone forever.
