Data

Between June 2024 and December 2024, tapwater samples were collected from 48 homes that use private well water as their drinking water source. All homes were located within a 50-kilometer radius of the 3M Cordova Facility in Cordova, Illinois, and analyzed for per- and polyfluoroalkyl substances (PFAS). The sampling effort was undertaken by the University of Iowa and samples were sent to...

Per- and polyfluoroalkyl substances (PFAS) and co-occurring constituents were assessed in the Upper Colorado River Basin during three sampling campaigns conducted from 2022 to 2024. In May 2022, discrete water samples were collected at five sites along a longitudinal transect from the Fraser River near Tabernash, Colorado to the Colorado River near Grand Junction, Colorado. Time series...

Eastern oyster (Crassostrea virginica) produced in a hatchery were maintained in cages at multiple sites in coastal Louisiana, and shell height, mortality, fecundity, and dermo were monitored to compare performance between genomically selected groups. Oysters were produced using genomic selection techniques targeting low-salinity tolerant oysters (high breeding value). To test...

Both aquatic and terrestrial insects can undergo complex evolutionary phases throughout their lifespan. Insects in a larval phase can accumulate and retain some chemicals, such as pesticides, throughout their various life cycles. Mature insects are often more mobile than their younger counterparts, making them able to transport pesticides over further distances. Insectivores (animals...

To better understand the pesticide exposure of bees (Bombus, Melissodes) while foraging in an agriculturally influenced landscape in Brookings County, South Dakota, bee tissue samples were collected from April/May through October in 2022 and 2023. Bees, included wild Bombus and Melissodes, were collected biweekly using blue vane traps and B. impatiens were collected from commercially...

Pesticide exposure is posited as one of the drivers of arthropod declines, which can in turn affect food availability and safety for vertebrates that consume insects including state and federally endangered species, such as the blunt nosed-leopard lizard (BNLL) (Gambelia sila). State wildlife areas and national wildlife refuges are designed to support species and their habitats; however...

The AltEn bioenergy plant (Mead, Nebraska, USA) previously (2015 to 2021) generated ethanol from almost 100% unused/expired treated corn seeds. This use of treated corn seeds as a feedstock for ethanol production resulted in accumulation of large amounts of contaminated wastewater and solid residue at the plant, a portion of which was applied to surrounding farmland. To evaluate the...

Wet meadow habitats in southeast Idaho, which are important areas for wetland-dependent wildlife, are managed by four National Wildlife Refuges (NWR). Threats to this important, but regionally declining habitat include pesticide drift from adjacent and nearby lands. In this study, four NWRs, Camas, Minidoka, Bear Lake, and Grays Lake, are investigated for the presence of pesticides...

Data include Per- and Polyfluoroalkyl Substance (PFAS) and pesticides measured in whole blood of male and female black (Ursus americanus) and grizzly (Ursus arctos horribilis) bears collected in the Cabinet-Yaak Ecosystem of Montana in 2023.

Concentrations for 26 PFAS detected in muscle tissues (edible fillets) of 16 estuarine fishes collected from four estuaries along Florida’s Atlantic coast between April 2021 and January 2023.

This dataset provides tables with photointerpretation of delayed mortality and associated predictors in Sentinel-2 pixels across conifer forests in Whiskeytown National Recreation Area.

This dataset includes photos taken in the field (Final_photos_for_data_release.zip) and a shapefile (Blackhollow_de.shp stored in Blackhollow_de.zip) to document debris flow activity in the Black Hollow watershed. The Black Hollow watershed was burned by the Cameron Peak Fire (13 August to 2 December 2020) and experienced a debris flow on 20 July 2021. The polygon shapefile in this...
