Greatest-density regions for GPS locations of bison (Bos bison) at Tallgrass Prairie National Preserve, 2021-2023 Greatest-density regions for GPS locations of bison (Bos bison) at Tallgrass Prairie National Preserve, 2021-2023
This GIS shapefile, "density_contours," describes 1) a bison study area at Tallgrass Prairie National Preserve, Kansas, and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2021-2023. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass, and approximate the

Benthic community composition and chemistry of water, sediment, and periphyton throughout a copper treatment to eradicate invasive mussels in the Snake River, Idaho, 2023 Benthic community composition and chemistry of water, sediment, and periphyton throughout a copper treatment to eradicate invasive mussels in the Snake River, Idaho, 2023
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...
Locations of bison (Bos bison) marked with GPS collars at Tallgrass Prairie National Preserve, 2021-2023 Locations of bison (Bos bison) marked with GPS collars at Tallgrass Prairie National Preserve, 2021-2023
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...
