Vegetation Composition and Management History Data (2015-2019) from Experimental Plots at Badlands NP, Wind Cave NP, and Scotts Bluff NM Used to Develop the ABAM Model Vegetation Composition and Management History Data (2015-2019) from Experimental Plots at Badlands NP, Wind Cave NP, and Scotts Bluff NM Used to Develop the ABAM Model
Plant species cover and richness data were collected in experimental plots at three sites: one at Badlands National Park (BADL), South Dakota, one at Scotts Bluff National Monument (SCBL), Nebraska, and one at Wind Cave National Park (WICA), South Dakota. At the Badlands and Scotts Bluff sites, data were collected in the summers of 2015 and 2017-2020 in 50 x 50-m plots with one of five...
Penstemon grahamii genetic data from a dryland region of the western United States Penstemon grahamii genetic data from a dryland region of the western United States
These data were compiled to investigate the evolutionary history of Graham's beardtongue (Penstemon grahamii). Objective(s) of our study were to determine the evolutionary history of P. grahamii, including ancestral population sizes, the history of population divergences, and historical connectivity. In addition, we characterized population structure, genetic diversity summary statistics...
Structure from motion products associated with UAS flights in Sandwich, Massachusetts between January 2016 - September 2017 Structure from motion products associated with UAS flights in Sandwich, Massachusetts between January 2016 - September 2017
Low-altitude (80-100 meters above ground level) Unmanned Aircraft Systems (UAS) imagery of Town Neck Beach in Sandwich, Massachusetts, were used in a structure-from-motion (SfM) photogrammetry workflow to create high-resolution topographic datasets. Imagery was collected at close to low tide on twelve days to observe changes in beach and dune morphology. Ground control points (GCPs)...
Innate Immunity and Stress and Reproductive Hormone Metrics for Southern Beaufort Sea Polar Bears, 2013-2015 Innate Immunity and Stress and Reproductive Hormone Metrics for Southern Beaufort Sea Polar Bears, 2013-2015
These were data collected from polar bears from the Southern Beaufort Sea during the spring between 2013 and 2015. Data include individual identification, demographic characteristics, year, status for the current and prior year regarding use of land, concentrations of stress response and reproductive hormones, blood-based biomarker measures indicative of fasting, body mass index, and...
Blood Parasite Infection, Body Mass, and Survival Data from Emperor Geese (Anser canagicus), Yukon-Kuskokwim Delta, Alaska, 2006-2016 Blood Parasite Infection, Body Mass, and Survival Data from Emperor Geese (Anser canagicus), Yukon-Kuskokwim Delta, Alaska, 2006-2016
This dataset provides two tables of blood parasite infection data collected from Emperor Geese (Anser canagicus) on Yukon-Kuskokwim Delta, Alaska, 2006-2016. Three genera of blood parasites (Leucocytozoon, Haemoproteus, Plasmodium) were detected by molecular sequencing of a 479 bp fragment of the Cytochrome-b gene. The data provided in the tables are: 1) age, sex, mass, infection status...

This data release presents two datasets including waterbodies (reservoirs, lakes, ponds, wetlands, etc.) and flowlines (stream reaches) from the high-resolution National Hydrography Dataset Plus (NHDPlus HR) that are potentially observable from Landsat images for the United States (excluding Alaska). To determine where National Hydrography Dataset Plus high resolution (NHDPlus HR; USGS...
Data for Simulating the Effects of Air Temperature and Precipitation Changes on Streamflow and Water Temperature in the Meduxnekeag River Watershed, Maine Data for Simulating the Effects of Air Temperature and Precipitation Changes on Streamflow and Water Temperature in the Meduxnekeag River Watershed, Maine
The U.S. Geological Survey (USGS), in cooperation with the Houlton Band of Maliseet Indians (HBMI), has developed tools to assess the effects climate change on hydrology and water temperatures in the Meduxnekeag River Watershed in Maine. A USGS Scientific Investigations Report (SIR) report documents tools and datasets developed by the USGS to evaluate how climate change will affect the...
