Per- and polyfluoroalkyl substances (PFAS) chemicals are known to strongly sorb onto soils when being transported downward through the vadose zone. The degree to which this sorption occurs depends on the length of the specific PFAS molecular chain and the properties of the soil. The properties with greatest influence on the soils PFAS sorption potential are percent silt and clay, and...

This dataset is one table with demographic, morphometric, and blood analyte measurements from whole blood and serum samples taken from a subset of polar bears sampled in Alaska's southern Beaufort Sea during 1989-2012. The measured blood analytes include: blood urea nitrogen, creatinine, glucose, total protein, hemoglobin, red blood cell count, packed cell volume, and hemoglobin A1c...

This dataset is one table with data collected and derived from polar bears sampled in Alaska from the Southern Beaufort Sea subpopulation during 2000-2023. Collected data includes individual identity, location of observation, observation type, estimated birth year, and demographic information. Data were collected from polar bears that were captured, remotely sampled using biopsy darts...

We sequenced the prion protein gene from white-tailed deer from Southwest Wisconsin. The samples were provided by the Wisconsin Department of Natural Resources. The dataset includes sequencing chromatogram files and a summary table with the interpretation of the sequencing data.

Grasslands are an imperiled ecosystem, and grassland bird abundance is declining across North America. One of the strongest drivers for these declines is woody plant encroachment of grasslands. In the Great Plains and Sagebrush biomes of North America, spatial covariance—a remote sensing metric for tracking boundaries between vegetation types—is emerging as a new method to identify and...

The objective of this project was to create a shoreline inventory for Hawai‘i Island, the largest and most diverse island in the Hawaiian archipelago. This was done via the collection and processing of high-resolution (

These spatial layers were created to provide estimates of non-native species invasion risk across the contiguous United States based on proximity to human population centers and transportation corridors, and proximity to known locations of non-native species. To calculate the human transport risk layer we estimated the proximity to human population centers, transportation corridors, and...

We conducted large-scale systematic surveys for native mussels across six reaches of the upper Mississippi River. In each reach, divers placed two 0.25 square meter quadrat frames on the river bottom. The duplicate quadrats, which were placed 10 m apart in an upstream to downstream direction, were used to increase the area sampled at each site and increase the effectiveness of this...

These are the northern long-eared bat (Myotis septentrionalis) summer month occupancy values derived from acoustic sampling and associated collection site environmental and weather covariates for the New England region, United States, 2015-2022.

This dataset compiles spatial occurrence and demographic information for six non-native invasive tree and shrub species—autumn olive, bush honeysuckles, Callery pear, princess tree, privet, and tree-of-heaven—across the eastern United States from 2000 to 2020. Occurrence points were obtained from the Early Detection and Distribution Mapping System (EDDMapS), and plot-level observations...

Climate change is substantially impacting earth’s biodiversity, with a massive number of affected species that are difficult to study comprehensively. An “indicator species” approach that generalizes species-specific climate change impacts to broader groups (e.g., ensembles) could theoretically help overcome this challenge and streamline climate-smart conservation planning. We assessed...

This data release provides spatial data for species distribution models developed for 24 stream fishes native to the Pacific Northwest, USA and associated model evaluation metrics used to determine the best supported model. These models support a larger analysis for understanding native stream fish vulnerability in the region, specifically population viability analyses built to determine...
