Luminescence data for: Reconstructing the Quaternary depositional history using geologic mapping and a 3D model of the subsurface in the vicinity of Fort Morgan, Eastern Colorado Luminescence data for: Reconstructing the Quaternary depositional history using geologic mapping and a 3D model of the subsurface in the vicinity of Fort Morgan, Eastern Colorado
Centered on Fort Morgan, Colorado, this study is intended to build from previous work by adding a three-dimensional (3D) view of the subsurface to better understand the depositional history of Quaternary deposits. A 1:100,000 scale geologic map was made by combining previous geologic maps, regional soil maps, and recent field investigations. In addition to the geologic mapping, drill...
Plains bison genetic data and genetic locus panel selection algorithm for monitoring conservation herds Plains bison genetic data and genetic locus panel selection algorithm for monitoring conservation herds
We developed and report a microsatellite data set composed of 52 microsatellite loci for 2305 individuals from 20 bison conservation herds (17 US federal, 1 tribal, 2 Canadian) and a single nucleotide polymorphism (SNP) data set composed of 5013 biallic loci for 376 individuals from 16 bison conservation herds that were used as part of a broader study. We also developed an algorithm to...
Geologic Radon Potential Map of the United States Geologic Radon Potential Map of the United States
Radon is an odorless and invisible radioactive gas that is naturally released from rocks, soil, and water. According to the U.S. Environmental Protection Agency (EPA) and the U.S. Surgeon General, radon is the second leading cause of lung cancer in the United States. Recent epidemiological studies have also identified linkages between radon exposure and cerebrovascular diseases including...
Genomic sequence polymorphisms among Corvus kubaryi of Rota, Northern Mariana Islands, inferred from samples collected between 2014 and 2024 Genomic sequence polymorphisms among Corvus kubaryi of Rota, Northern Mariana Islands, inferred from samples collected between 2014 and 2024
This study generated genetic polymorphism data at a genome scale by whole-genome shotgun DNA sequencing of Mariana Crow (Corvus Kubaryi). DNA was extracted from blood tissue originally collected nonlethally from field monitoring efforts, captive rearing, and carcasses, under permit of the US Fish and Wildlife Service. Sequencing libraries were generated for the Illumina sequencing...
Analysis of historic orthomosaic imagery collected through various agencies for mapping active channel and floodplain changes along a 22.5-km reach of the Green River at Gray Canyon near Green River, Utah from 1938-2021 Analysis of historic orthomosaic imagery collected through various agencies for mapping active channel and floodplain changes along a 22.5-km reach of the Green River at Gray Canyon near Green River, Utah from 1938-2021
The U.S. Geological Survey gathered historic aerial photography and remote sensing imagery from a variety of sources for mapping channel change along a 22.5-kilometer reach of the Green River at Gray Canyon near Green River, Utah. Imagery was downloaded in .TIF format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et al. 2021) using Agisoft Metashape...
Model outputs of habitat suitability for three invasive tegu lizards across the contiguous United States under current and future climate scenarios Model outputs of habitat suitability for three invasive tegu lizards across the contiguous United States under current and future climate scenarios
This data release is comprised of two datasets; 1) a .tif file containing species distribution model (SDM) outputs for three invasive tegu species (Salvator merianae, S. rufescens, Tupinambis teguixin) across the contiguous United States (CONUS) for three climate scenarios (current, +2 degree C warming and +4 degree C warming). We are providing a stacked raster (9 layers total), with a...
Data and analytical code to model the growth rate of brown treesnakes (Boiga irregularis), Guam 2004-2013 Data and analytical code to model the growth rate of brown treesnakes (Boiga irregularis), Guam 2004-2013
The data set consists of three files pertaining to invasive Brown Treesnakes (Boiga irregularis) and temporally-associated weather covariates on Guam: 1) snout-vent length (SVL) and sex of brown treesnakes (bts_growth.csv), 2) precipitation (bts_rain.csv), and 3) seasonality (bts_season.csv). Snout-vent lengths in millimeters (mm) and sex of 270 individually marked and recaptured brown...
Morphometric data of Burmese python and White-tailed deer in South Florida associated with a feeding event, 2025 Morphometric data of Burmese python and White-tailed deer in South Florida associated with a feeding event, 2025
Morphometric data (mass, length, circumference, age) collected during an observation of a radio-telemetered female Burmese python (Python bivitattus) that ingested an adult female white-tailed deer (Odocoileus virginianus), retained the deer within the digestive tract for 10 days, and then vomited the deer coinciding with a drop in air temperature.
Luminescence data for: Trench Exposures across the Dead Coyote fault scarp in Kittitas Valley, Washington Luminescence data for: Trench Exposures across the Dead Coyote fault scarp in Kittitas Valley, Washington
The Wallula fault zone is an integral feature of the Olympic-Wallowa lineament, an ∼500-km-long topographic lineament oblique to the Cascadia plate boundary, extending from Vancouver Island, British Columbia, to Walla Walla, Washington. The structure and past earthquake activity of the Wallula fault zone are important because of nearby infrastructure, and also because the fault zone...
Data Describing Effects of Bison (Bison bison) Herbivory on Herbaceous Production and Nitrogen Yield throughout Grand Canyon Grasslands from 2021 to 2022 Data Describing Effects of Bison (Bison bison) Herbivory on Herbaceous Production and Nitrogen Yield throughout Grand Canyon Grasslands from 2021 to 2022
This dataset includes three datasets collected in 2021 and 2022 to assess the potential effects of bison (Bison bison) herbivory and climate on grassland functional properties throughout semi-arid meadows in Grand Canyon National Park and Kaibab National Forest of northern Arizona. Bison herbivory offtake (utilization) and aboveground herbaceous production are demonstrated in the...
GPS Locations of Free-roaming Burros in Utah and Arizona, USA, 2016 to 2020 GPS Locations of Free-roaming Burros in Utah and Arizona, USA, 2016 to 2020
This dataset includes locations of burros between 2016 and 2020 from two study areas where burros were located every 2 hours continuously using GPS telemetry collars for Lotek collars, and every 13 hours continuously for Vectronic Aerospace collars.
