Invasive Central American boas (Boa imperator) have established a reproducing population on the western side of St. Croix, U.S. Virgin Islands, as shown by increasing physical capture rates. However, their prevalence throughout the island is largely unknown. The large snakes threaten endemic and endangered species through competition and predation, jeopardizing island biodiversity...

Paleogeologic information directly above (supracrop) and below (subcrop) geologic periods from U.S. Geological Survey (USGS) reports was digitized from scanned plates. Geologic periods maps include the Jurassic (McKee and Others, 1956), Triassic (McKee and Others, 1959), Permian (McKee and McKee, 1967), Pennsylvanian (McKee and Crosby, 1975), and Mississippian (Craig and Connor, 1979)...

As the Arctic physical environment undergoes rapid change, permafrost conditions also are shifting. Thawing of ice-rich permafrost can cause terrain instability and compromise infrastructure as the permafrost excess ice content (EIC) melts – EIC refers to the volume of ground ice that exceeds the soil’s pore space when thawed. This dataset provides EIC depth measurements from 38...

Mineralized breccias at Hicks Dome, Illinois host abundant fluorspar, Pb-Zn sulfides, barite, rare earth elements (REE), and high field strength elements (HFSE). The REE+HFSE mineralogy of breccias between 600 and 900 meters were examined and mineral compositions were determined by electron probe microanalysis (EPMA), using a JEOL 8530F Plus field emission electron microprobe at the U.S

The United States Geological Survey (USGS) collected a total of 179 samples of surficial sediment from abandoned mine wastepiles, ephemeral channels below wastepiles, nearby outcrops, and background areas representative of the undisturbed lithology within the Henry Mountains and Fremont mining districts (Krahulec, 2018). The samples are associated with the following mining claims within...

A digital version of the 1:500,000 scale geologic map of Alabama (Osborne and others, 1989) was required for a new national compilation of state geologic maps and U.S. Geological Survey regional maps, but the map had not previously been digitized. The USGS National Cooperative Geologic Mapping Program’s (NCGMP) National Geologic Synthesis Project worked with the Geological Survey of...

Quantitative PCR results for surveillance of New Zealand mudsnail environmental DNA at the U.S. Fish and Wildlife Service Alchesay National Fish Hatchery.

Population level summary data on survival, reproduction, and population size used to estimate demographic rates and population size for two peregrine falcon management populations in North America using integrated population models. The data are provided in a CSV file and in management population (northern and southern) and model scenario (original, extrapolated, updated) specific R...

Data containing field observations of potential Jemez Mountains salamander (JMS; Plethodon neomexicanus) cover objects and characteristics of underlying soils, concurrent with arthropod data collected from pitfall traps beneath selected cover objects in salamander historic habitat located in the Jemez Mountains, New Mexico from 2023-2024. We sampled potential salamander prey items...

This dataset includes stream and species data collected in headwater streams on public lands throughout the eastern United States. Data were collected to inform updated species range maps and provide data for large-scale modeling of species ranges using multiple data types. All salamander species encountered are included in the dataset.

This U.S. Geological Survey data release presents the study area boundary and surficial hydrogeologic units for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert. The study area boundary delineates a spatial extent defined to include the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert. Within this boundary, surficial hydrogeologic...

This data release contains historical and future climate SnowModel (Liston and Elder, 2006; Liston and others, 2020; Liston, 2020) simulation outputs on a 100-meter (m) geospatial grid for a 392-kilometer (km) x 469-km model domain in the Upper Colorado River Basin. The historical simulation (control, CTL) was run from 1979-09-01 to 2022-08-31 using the CONUS404 meteorology dataset...
