Digital database of the previously published Geologic Map of Alabama (Special Map 221) Digital database of the previously published Geologic Map of Alabama (Special Map 221)
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.
Survival, productivity, and population index data used to estimate demographic rates and population size for two peregrine falcon management populations in North America, 1980-2024 Survival, productivity, and population index data used to estimate demographic rates and population size for two peregrine falcon management populations in North America, 1980-2024
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...
Arthropod abundance across a fire severity gradient beneath potential cover objects throughout the Jemez Mountains, New Mexico, USA 2023-2024. Arthropod abundance across a fire severity gradient beneath potential cover objects throughout the Jemez Mountains, New Mexico, USA 2023-2024.
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...
Salamander species in headwater streams on state and federal public lands in the eastern United States Salamander species in headwater streams on state and federal public lands in the eastern United States
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.
Study Area Boundary and Surficial Hydrogeologic Units for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert Study Area Boundary and Surficial Hydrogeologic Units for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert
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...
