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.

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. Location data are from adult female burros, not males. Study areas are the Lake Pleasant Herd Management Area in Arizona, USA and the Sinbad...

Data describing species consumed by mountain lions during predation events in eastern Nevada, USA, 2018 to 2022 Data describing species consumed by mountain lions during predation events in eastern Nevada, USA, 2018 to 2022

This dataset consists of 1,353 ground observer investigations of mountain lion predation events ("kills") in eastern Nevada, USA, from 2018 to 2022. Over the period of the data collection, we had 29 mountain lions equipped with telemetry collars and we investigated clusters of locations when GPS collar locations were in the same area for three nights -- we used this criteria to identify...

Data Describing Effects of Telemetry Collars on Horses and Burros Between 2016 and 2020 Data Describing Effects of Telemetry Collars on Horses and Burros Between 2016 and 2020

This dataset includes a number of datasets collected to assess the potential effects of GPS telemetry collars on free-roaming feral equid species in North America: horses and burros. The behavior dataset (Behavioral_data_collared_uncollared.csv) includes frequency of maintenance behaviors of collared and un-collared horses at Conger Herd Management Area (HMA), and burros at Lake Pleasant...

Data on behavior of adult horses and burros between 2016 and 2020, in Utah and Arizona, USA Data on behavior of adult horses and burros between 2016 and 2020, in Utah and Arizona, USA

We investigated the behavior of feral horses (Equus caballus) at Conger Herd Management Area (HMA), UT, and of burros (Equus asinus) at Lake Pleasant HMA, AZ, and Sinbad HMA, UT between 2016 and 2020 (Sinbad HMA 2016 to 2019; Conger and Lake Pleasant HMAs 2017 to 2020). We collected data on the time budget and social behavior of adults (2 years old and older) between April and September...

Amplicon sequencing of pollen foraged by multiple bee species in units of the National Park Service, National Capital Region, 2021-2022 Amplicon sequencing of pollen foraged by multiple bee species in units of the National Park Service, National Capital Region, 2021-2022

This study generated genetic 'metabarcode' data using high-throughput sequencing to characterize pollen foraging behavior of pollinating bee species on managed field habitat within units of the National Park Service. Specimens were collected within parks of the National Capital Region from 2021-2023 and subsequently identified to species or genus. DNA was then extracted from specimens...

Amplicon sequencing of pollen foraged by Bombus affinis for compositional analysis, 2021-2023 Amplicon sequencing of pollen foraged by Bombus affinis for compositional analysis, 2021-2023

This study generated genetic 'metabarcode' data using high-throughput sequencing to characterize pollen foraging behavior of the endangered rusty-patched bumblebee, Bombus affinis. Pollen samples were collected primarily from forest meadow habitats in the Appalachian piedmont of the eastern United States, specifically within the states of Virginia and West Virginia. Three additional...
