Relation between Plant Community Structure and Function and the Effectiveness of Wetland Restoration Efforts
High rates of wetland loss continue to occur along the northern Gulf of Mexico coast, and this remains an issue of concern to resource managers.
The Bureau of Ocean Energy Management (BOEM) uses trawling to capture and relocate live sea turtles away from dredging locations to minimize the risk of turtle entrainment. These incidental turtle captures provide a unique opportunity to fill critical data gaps for difficult to capture life-stages of marine turtles.
Distribution and Density of Sea Turtles in the Gulf of Mexico (GOM): Gulf of Mexico Marine Assessment Program for Protected Species (GoMMAPPS)
The over-arching goal of GoMMAPPS is to collect broad-scale survey data for seabirds, marine mammals and sea turtles to determine distribution and abundance in the Gulf of Mexico.
Integrating Science and Management for Optimal Prevention and Control of Invasive Nymphoides in Florida
Two invasive species of floating hearts, Nymphoides cristata and N. indica, are actively managed in Florida. A rare native species, N. humboldtiana, has been found in Florida and verified by molecular methods; this species is nearly indistinguishable from N. indica.
Scientific Support of Salmon and Steelhead Reintroductions in Impounded River Basins of the Pacific Northwest
Salmon and steelhead populations in the Pacific Northwest were severely affected by hydropower development that occurred during the first half of the 20th century. Impassable dams were constructed on many rivers throughout the region which prevented returning adult salmonids from accessing important habitats where spawning and rearing historically occurred. In the past two decades...
Relict forests (i.e., forests unable to reestablish after disturbance) may develop in the southeastern U.S. in future predicted extreme climates of temperature, flooding, and drought, according to the International Panel on Climate Change.
The objective of this research is to assess the sensitivity of female and male LMB reproductive capabilities at the time of year when they are physiologically preparing for spawning season (also known as gonad recrudescence).
Avian influenza is a viral disease caused by various strains of avian influenza viruses that can be classified as low pathogenic avian influenza (LPAI) or highly pathogenic avian influenza (HPAI). It remains a global disease with potential high consequence with the potential to threaten wildlife, agriculture, and human health.
The USGS National Wildlife Health Center (NWHC) serves on the U.S. Interagency Steering Committee for Surveillance for Highly Pathogenic Avian Influenza in Wild Birds to standardize surveillance for this disease and is a leading partner in conducting morbidity and mortality investigations in support of the Interagency Strategic Plan for Early Detection and Monitoring for Avian Influenzas of...
The USGS National Wildlife Health Center (NWHC) provides the following index of wildlife disease information resources as a starting point to learn about selected wildlife diseases. The index includes informational web pages and communications and outreach products from the NWHC. To search for scientific literature, please visit the USGS Publications...
Snake River fall Chinook salmon were listed as “threatened” under the Endangered Species Act in 1992. At that time, little was known about the spawning, rearing, migration, and life history of this species. This long-term research and monitoring project has produced much of the contemporary knowledge on fall Chinook salmon that has been used by fish managers to implement recovery measures. The...
USGS research on wildlife behavior, abundance, and sources of mortality are improving our understanding of the specific effects of renewable energy on wildlife and habitats. This knowledge is guiding the development of effective strategies to minimize the impact of renewable energy development on wildlife. USGS is improving and developing software models and statistical tools that can be used...
