This GIS shapefile, "density_contours," describes 1) a bison study area at Wind Cave National Park, South Dakota, and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2019-2024. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass, and approximate the...

This GIS shapefile, "density_contours," describes 1) a bison study area in the North Unit of Theodore Roosevelt National Park, North Dakota and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2017-2020. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass...

This dataset includes information collected before and after a 2023 copper treatment was implemented by the State of Idaho to eradicate invasive quagga mussels in the Snake River, Idaho. Water, sediment, periphyton, and macroinvertebrates were sampled at Snake River sites upstream, within, and downstream of the copper treatment reach in order to evaluate the fate and transport of the...

The GIS shapefile "bison_locations" provides 132996 locations of 5 adult female bison marked with global positioning system (GPS) collars at Tallgrass Prairie National Preserve during February 2021 to November 2023. We provide locations computed at 15-min and 1-h intervals for individual bison and the date and time of acquisition for each location. Users are advised that ground...

This GIS shapefile, "density_contours," describes 1) a bison study area at Badlands National Park, South Dakota, and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2015-2024. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass, and approximate the...

This data release includes laboratory analyses for biofilm and bed-sediment samples collected from streams in the Clark Fork Basin, spanning from Butte to near Missoula, Montana. Samples were collected by the U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency as part of a long-term monitoring program. Biofilm samples were collected once at 19 sites...
