High-resolution maps of projected big sagebrush plant community biomass for 52 future climate scenarios using multivariate matching algorithms High-resolution maps of projected big sagebrush plant community biomass for 52 future climate scenarios using multivariate matching algorithms
These data were compiled for the study: Divergent climate change effects on widespread dryland plant communities driven by climatic and ecohydrological gradients. The objectives of our study were to (1) describe how climate change will alter the biomass and composition of key plant functional types; (2) quantify the impacts of climate change on future functional type biomass and...
High-resolution maps of historical and 21st century ecological drought metrics using multivariate matching algorithms for drylands of western U.S. and Canada High-resolution maps of historical and 21st century ecological drought metrics using multivariate matching algorithms for drylands of western U.S. and Canada
These data were compiled using a new multivariate matching algorithm that transfers simulated soil moisture conditions (Bradford et al. 2020) from an original 10-km resolution to a 30-arcsec spatial resolution. Also, these data are a supplement to a previously published journal article (Bradford et al., 2020) and USGS data release (Bradford and Schlaepfer, 2020). The objectives of our...
Location Data for Petrographic Samples and Isotopic and Age Data from Detrital Zircon Grains from Selected Rock Samples from St. Lawrence Island and the Western Brooks Range, Alaska Location Data for Petrographic Samples and Isotopic and Age Data from Detrital Zircon Grains from Selected Rock Samples from St. Lawrence Island and the Western Brooks Range, Alaska
This dataset contains a list of geologic station localities on St. Lawrence Island, Alaska, from which thin section samples were examined. The dataset also contains U-Pb isotopic data and ages of detrital zircon (DZ) from sedimentary rocks collected on St. Lawrence Island and in the western Brooks Range. All St. Lawrence Island samples (DZ and thin sections) were collected by U.S...
Data Used to Assess the Acute Physiological Response of Polar Bears to Helicopter Capture Data Used to Assess the Acute Physiological Response of Polar Bears to Helicopter Capture
This dataset is in five tables with data from ecophysiological studies of free-ranging polar bears of the Southern Beaufort Sea subpopulation. They were equipped with high-resolution activity sensors, body temperature loggers, and GPS satellite-telemetry collars, to compare physiological state and activity of bears during natural behavior with that experienced by bears during helicopter...
Data from a 2019 occupancy survey of alligator snapping turtles, Macrochelys temminckii, in south-central Louisiana Data from a 2019 occupancy survey of alligator snapping turtles, Macrochelys temminckii, in south-central Louisiana
This dataset contains data on trapping methodology, turtle captures, and environmental variables from a trapping effort targeting alligator snapping turtles (Macrochelys temminckii) in south-central Louisiana in 2019.
Co-occurance Simulation Modeling Co-occurance Simulation Modeling
R-based script used to simulate patterns of co-occurrence among two hypothetical species under patterns of avoidance, aggregation, and independence when the closure assumption is met or not, analyze simulated patterns with two-species occupancy models, and summarize the results.
