Statistical Models for the Design and Analysis of Environmental DNA (eDNA) Surveys of Invasive and Imperiled Species
Detecting invasive species at low densities or prior to population establishment is critical for successful control and eradication. For example, Burmese pythons occupy thousands of square kilometers of mostly inaccessible habitats.
Preserving Gulf Sturgeon—A Fish Tale of Gargantuan Proportions
It's hard to imagine a better job than doing fieldwork with the USGS Coastal Ecology crew as they work to keep tabs on the Gulf sturgeon population.
Paddlefish Tracking Map - Visualizing U.S. Fish and Wildlife Service Tower and Boat Observational Data
Partnering with the Caddo Lake Institute, the USGS WARC Advanced Applications Team developed a web-based mapping application that visualizes the paddlefish tracking observations being collected by FWS.
Flow Cytometry Applied to the Animal Kingdom in Studies of Natural Resource Science
Flow cytometry is a technique for rapidly analyzing large numbers of animal cells using light-scattering, fluorescence, and absorbance measurements.
American Fisheries Society List of Freshwater Snails from Canada and the United States
This website provides access to the list of freshwater gastropods (snails) in Canada and the United States as determined by the 2013 American Fisheries Society (AFS) Endangered Species Committee (ESC) on freshwater gastropods.
American Fisheries Society Crayfish of the United States and Canada
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.
Developing a Largemouth Bass Hybrid Strain for Mapping Genome Linkage
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.
Population Demography and Food Web Analysis of Large Aquatic Salamanders (Siren and Amphiuma) in North Florida
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.
Climate Envelope Modeling for Evaluating Anticipated Effects of Climate Change on Threatened and Endangered Species
Modeling both potential changes in climate and responses of species and habitats can increase certainty in management decisions by helping managers to understand the range of possible species and habitat responses under different alternative futures. Climate envelope modeling is one type of modeling that can be useful in understanding species and habitat responses to climate change because it...
Coral Bleaching and Disease: Effects on Threatened Corals and Reefs
A severe disease - tentatively named stony coral tissue loss disease - is rapidly killing corals in the U.S. Virgin Islands. Scientists from the U.S. Geological Survey, the University of Puerto Rico, and the National Park Service are working together to better under the disease and determine if the disease affecting corals in the USVI is the same one that has been killing corals in Florida since...
Winter Manatee Foraging Behavior and the Decline of Seagrass Beds in the Northern Indian River Lagoon
With high numbers of manatees using the Florida Power and Light power plant warm water refuge during winter, their impact on the seagrass beds in the Indian River Lagoon is considered an important indicator of the long-term capacity of the area to support the manatees. USGS is working with partners to investigate the spatial extent and intensity of manatee use of seagrass beds in the area.
Parasites of Imported and Non-Native Wild Asian Swamp Eels
In parts of Asia, wild-caught and aquaculture-reared swamp eels are widely consumed as food by humans and are a common source of human gnathostomiasis, a food-borne zoonosis caused by parasitic nematodes of the genus Gnathostoma spp. In humans, the larvae of these nematodes can cause tissue damage and, in some instances, death. Over the past two decades, many thousands of Asian swamp eels have...
