The data contained in child items of this page were developed to support the Species Status Assessments conducted by the U.S. Fish & Wildlife Service and conservation planning for State, Federal, and non-government researchers, managers, landowners, and other partners for five focal herpetofauna species: gopher tortoise (Gopherus polyphemus), southern hognose snake (Heterodon simus), Florida pine snake (Pituophis melanoleucus mugitus), gopher frog (Lithobates capito), and striped newt (Notophthalmus perstriatus). These data were developed by the USGS Cooperative Fish & Wildlife Research Unit at the University of Georgia in collaboration with other partners. The three child items contain the following data: (1)...

The three datasets were used in a model estimating the current and future persistence of 222 populations of southern hognose snakes, as estimated as part of the USFWS Species Status Assessment. Because these datasets contain information about sensitive species at risk of overcollection and harassment, they do not contain any spatial identifying information. The "HESIM_locs" dataset contains a list of southern hognose snake occurrence records with associated year of observation and population ID. The "SEsnakes_locs" dataset contains a list of non-target snake species occurrence records with associated year of observation and population ID. The "HESIM_pops_all" dataset contains a list of southern hognose snake populations...

Funding for this study was provided by the U.S. Geological Survey (Cooperative Agreement nos. G12AC20329, G15AC00264) and the South Carolina Department of Natural Resources (Grant nos. 2009094, 20100899). This study examines drivers of American alligator (Alligator mississippiensis) population dynamics in South Carolina. Study objectives are to (1) estimate demographic parameters and abundance from marked alligators and nightlight surveys in an integrated population modeling framework, (2) optimize nightlight survey monitoring design to maximize abundance estimate accuracy and precision and minimize costs, (3) identify an optimal harvest strategy to maintain population stability and limit changes to size class...

This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 4 and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations and seasonal ranges. This data release provides the means for ungulate migrations to be mapped and planned for across a wide variety of landscapes where they occur. Due to data sharing constraints of participating agencies, not all the files that underlie the mapped migrations included in the report have been released. Data in this archive can be downloaded two ways. To download by individual herd/range, clicking on child item pages...

The raster data in the geodatabase represent range-wide habitat suitability model predictions for five species of herpetofauna: gopher tortoise (Gopherus polyphemus), southern hognose snake (Heterodon simus), Florida pine snake (Pituophis melanoleucus mugitus), gopher frog (Lithobates capito), and striped newt (Notophthalmus perstriatus). Collectively, the habitat suitability rasters extend across the range of these species in the Southeast US, including areas in Louisiana, Mississippi, Alabama, Florida, Georgia, South Carolina, and North Carolina. This assessment was conducted by the USGS Cooperative Fish & Wildlife Research Unit at the University of Georgia in collaboration with other partners. Habitat suitability...

The Eastern Brown Pelican (Pelecanus occidentalis carolinensis) is a large-bodied seabird that nests in colonies of 10 to upwards of 5,000 pairs, on nearshore islands in subtropical and tropical North American waters. It breeds between March and August, laying 2–3 eggs and raising 1–2 chicks per year. The species is facultatively migratory during nonbreeding, with some individuals remaining resident and others leaving breeding areas. Pelicans forage in near- and offshore waters and capture schooling fish by plunge-diving. This dataset summarizes taxonomical information for all prey species identified in the diet of Brown Pelican collected in 2013-2015 at 10 breeding colonies in the northern Gulf of Mexico from...

In the spring of 2018, we studied the foraging ecology of the Black-capped Petrel. The goal of this project was to gather fine-scale data on individual movements of Black-capped Petrels breeding in the Sierra de Bahoruco, Dominican Republic. Our objective was to use GPS tracking devices to identify the foraging behavior and the locations and environmental characteristics of foraging areas of breeding Black-capped Petrels in the Caribbean Sea. We provide results from the deployment of nine remote-download GPS loggers on breeding Black-capped Petrels from Sierra de Bahoruco during April 2018.

Funding for this study was provided by the Bureau of Ocean Energy Management and U.S. Geological Survey (Interagency Agreement no. M12PG00014). This study focuses on obtaining information about populations of Brown Pelican (Pelecanus occidentalis carolinensis) across the northern Gulf of Mexico. Study objectives are to (1) document dispersal, seasonal and annual movements, seasonal home range, and site fidelity of marked adult Brown Pelicans among nesting colonies from the Gulf coast, (2) compare contaminant exposure risk, contaminant levels, and health parameters in adult and nestling Brown Pelicans from various colony sites, and (3) document the relationship of local environmental, nest site characteristics and...

Funding for this study was provided by the U.S. Geological Survey Ecosystem Missions Area, and facilitated by Mona Khalil (USGS). This study focuses on filling knowledge gaps related to populations of Brown Pelican (Pelecanus occidentalis carolinensis) across the South Atlantic Bight. Study objectives are to (1) document seasonal and annual movement patterns of adult pelicans, including foraging patterns, migration, wintering sites, and home range, (2) examine contaminant loads related to key foraging areas, (3) document the effects of fishery bycatch on pelican reproduction, (4) provide risk assessments for different colonies of pelicans related to various oil spill scenarios, and (5) describe the activity patterns...

As part of a larger effort to examine individual-based movement patterns and habitat use at sea for seabirds in the Caribbean, a tracking study of Masked Boobies (Sula dactylatra) breeding on the Pedro Cays, Jamaica, was implemeted in 2012. This population is one of the largest of the few breeding groups in the region. The Masked Booby is considered to be declining and regionally-threatened with ca. 500-700 nests in the West Indies. This species faces numerous conservation threats at colony sites and potentally at foraging grounds. Management could be enhanced if data were available regaridng foraging ranges during the breeding season as well as extent of the wintering range. Therefore, the goal of this pilot project...

The Seabird Colony Registry (data) and Atlas (spatial inventory) for the southeastern US compiles the locations, estimates of nesting populations, and attributes of seabird colonies, from the northern border of South Carolina to approximately Cape Canaveral, Florida from 2003-2017. The documentaion available here is a companion to the registry and atlas: it provides background information and objectives, geographical extent, time frame, methofs for data collection and compilation, and instructions on the use of the Atlas. The documentation also lists product limitations and disclaimers.
