Manatee Health Assessment and Biomedical Studies
A multi-agency effort assesses the health of manatees and provides baseline information on their health, reproductive status, and nutritional condition.
Monitoring Effects of Barrier Island Restoration on Piping Plovers in Louisiana
The federally threatened piping plover relies on sand-beach habitat year-round for nesting, foraging, and roosting, habitat that is particularly vulnerable to loss and degradation from coastal development, recreation activities, erosion, and sea-level rise.
Distribution and Density of Sea Turtles in the Gulf: Gulf of America Marine Assessment Program for Protected Species (GoAMAPPS)
The over-arching goal of GoAMAPPS is to collect broad-scale survey data for seabirds, marine mammals and sea turtles to determine distribution and abundance in the Gulf.
Sturgeon Occurrence and Behavior in the Outer Continental Shelf
A new study aims to collect information on sturgeon temporal and spatial distribution to inform offshore wind energy and sand leasing operations.
Gulf Sturgeon Ecological Investigations
The Gulf sturgeon, Acipenser oxyrinchus desotoi, has been listed as Threatened since 1991. Beginning in 1986, USGS has been investigating sturgeon population abundance and ecology throughout its range, but mostly in the Suwannee River.
Fine-Scale Dive Profiles and Activity Patterns of Sea Turtles in the Gulf
Researchers are developing acceleration data logger pop-off packages that can be affixed to sea turtles to collect behavioral patterns of diving, surfacing, and general activity levels.
Sea Turtle Movement and Habitat Use in the Northern Gulf
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.
Understanding Avian Habitat Availability and Use After Barrier Island Restoration in Coastal Louisiana
Using ecological and geographical data, WARC researchers and their partners are analyzing avian and benthic sampling on Whiskey Island and Caminda Headland to compare pre- and post-restoration aspects of habitat occupancy, habitat availability, habitat use, and kernal density estimation.
Manatee Distribution and Habitat Use in the Northern Gulf
USGS works with partners to assess manatee distribution and habitat use throughout the Northern Gulf.
Hotspot and Risk Analysis for Sea Turtles in the Florida Keys National Marine Sanctuary
Researchers will collect location data that will be used to identify areas of high-use for resident sea turtles in the Florida Keys National Marine Sanctuary.
Sea Turtle Nesting on Eglin Air Force Base Property, Cape San Blas, Florida
The Northwestern Atlantic population of loggerhead sea turtles is one of the largest in the world. Genetic studies have divided this population into 5 management units including a genetically distinct group that nests throughout the northern Gulf.
Conservation Ecology of Hawaiian Forest Birds
Many of Hawai‘i’s forest birds have shown significant declines in the past 200 years, with many currently listed as endangered species. Multiple threats have been identified as contributing to declines, including disease, invasive species, habitat loss, and decreased survivorship and productivity caused by introduced predators. Through a combination of demographic information, population modeling...
