Species Biology

"BearTrak" is an app that provides a central repository for Louisiana black bear tracking data, allowing managers to access information more quickly and reliably. USGS science was used in the decision to delist the species from the Endangered Species Act in 2016. Louisiana Department of Wildlife and Fisheries continues to monitor the Louisiana black bear population.

A multi-agency effort assesses the health of manatees and provides baseline information on their health, reproductive status, and nutritional condition.

USGS will deploy a small, portable radar aboard a National Oceanic and Atmospheric Administration research vessel to measure the abundance, geographic distribution, and flight altitude of birds migrating across the continental shelf of the northern Gulf.

USGS researchers are conducting research on St. Vincent National Wildlife Refuge and throughout coastal habitat in Northwest Florida to inform future management decisions in the Refuge and contribute to the growing knowledge of the ecology of gopher tortoises using coastal habitats.

In response to declining populations, researchers at WARC are collecting data on demographics, movement patterns and habitat use, ecological niche and foraging ecology, and nesting ecology of diamondback terrapins.

Through a collaborative effort with other federal agencies and academic and research institutions, the USGS is working to inform and enhance the protection and management of coral communities in mesophotic and deep benthic areas of the Gulf.

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.

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.

A new study aims to collect information on sturgeon temporal and spatial distribution to inform offshore wind energy and sand leasing operations.

Researchers are investigating beach compaction, the incubation environment for turtle nests, and shorebird nest abundance at beaches throughout the southeastern United States to better understand the impacts of beach compaction to nesting turtles and foraging seabirds.

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.

USGS scientists are using a spatially-explicit Bayesian network model to predict the difference between energetic value and energetic demand for stopover habitats for migrating landbirds.
