POPMAPS: An R package to estimate ancestry probability surfaces POPMAPS: An R package to estimate ancestry probability surfaces
This software code was developed to estimate the probability that individuals found at a geographic location will belong to the same genetic cluster as individuals at the nearest empirical sampling location for which ancestry is known. POPMAPS includes 5 main functions to calculate and visualize these results (see Table 1 for functions and arguments). Population assignment coefficients...
Rainbow trout reproduction data from 3 sampling trips (2018-2019) within Glen Canyon, AZ Rainbow trout reproduction data from 3 sampling trips (2018-2019) within Glen Canyon, AZ
These data were compiled to describe population reproductive structure of rainbow trout in the Colorado River downstream of Glen Canyon Dam, Arizona. Objective(s) of our study were to describe the population on reproductive structure of the rainbow trout population in Glen Canyon on the Colorado River and evaluate the accuracy of nonlethal methods (manual expression and ultrasonography)...
Historical and future ecological drought conditions for rangelands of the western U.S. Historical and future ecological drought conditions for rangelands of the western U.S.
These NetCDF data were compiled to investigate how rangelands in the western U.S. are limited by access to water. As a result, these ecosystems may be especially vulnerable to changes in water availability and drought as a result of climate change. This project utilized an ecosystem water balance model to quantify spatial and temporal patterns of rangeland ecological drought conditions...
High-resolution maps of historical and 21st century soil temperature and moisture data using multivariate matching algorithms for drylands of western U.S. and Canada High-resolution maps of historical and 21st century soil temperature and moisture data using multivariate matching algorithms for drylands of western U.S. and Canada
These data were compiled as a supplement to a previously published journal article (Bradford et al., 2019), that employed a ecosystem water balance model to characterize current and future patterns in soil temperature and moisture conditions in dryland areas of western North America. Also, these data are associated with a published USGS data release (Bradford and Schlaepfer, 2019). The...
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...
Ecological property data and experimental lab incubation results from a long-term nitrogen deposition simulation experiment in three semi-arid grasslands, Arches National Park, Utah, USA, 2013-2019 Ecological property data and experimental lab incubation results from a long-term nitrogen deposition simulation experiment in three semi-arid grasslands, Arches National Park, Utah, USA, 2013-2019
These data were compiled to understand the responses of dryland ecosystem properties to long-term simulated atmospheric nitrogen deposition. Objective(s) of our study were to uncover any changes in soil biogeochemistry and ecosystem properties to long-term nitrogen amendments. These data represent ecosystem property data compiled over the nine-year history of a nitrogen deposition...
Digital elevation models and water surface profiles for the Colorado River in Cataract Canyon, Canyonlands National Park and Glen Canyon National Recreation Area, Utah Digital elevation models and water surface profiles for the Colorado River in Cataract Canyon, Canyonlands National Park and Glen Canyon National Recreation Area, Utah
These data consist of measurements of riverbed and floodplain bathymetry and topography, measurements of water-surface elevations and ancillary data. These data are specific to the corridor of the Colorado River from the confluence of the Green and Colorado Rivers near Spanish Bottom, Utah in Canyonlands National Park to the confluence with the Dirty Devil River in Glen Canyon National...
Colorado River Delta Project: A compilation of vegetation indices, phenology assessment metrics, and estimates of evapotranspiration for circular bird plots in the Colorado River delta between 2000-2020 (ver. 1.0) Colorado River Delta Project: A compilation of vegetation indices, phenology assessment metrics, and estimates of evapotranspiration for circular bird plots in the Colorado River delta between 2000-2020 (ver. 1.0)
These data were compiled to understand the effects of riparian vegetation health on local abundance and species diversity of land birds. The primary objective of our study was to to determine the effects of riparian restoration on birds in the Colorado River delta. These tabular data represent vegetation indices and evapotranspiration (ET) data at varying spatial scales that correspond...
Biocrust cover, vegetation, and climate data from a protected grassland within Canyonlands National Park, Utah (ver. 2.0, Sept. 2023) Biocrust cover, vegetation, and climate data from a protected grassland within Canyonlands National Park, Utah (ver. 2.0, Sept. 2023)
These tabular data were compiled for/to monitor vegetation and biocrust cover in a never grazed grassland located in Canyonlands National Park. An objective, or objectives, of our study was to document potential changes in biocrust and vegetation cover and species composition as related to changes in land use and climate change. These data represent a timeseries of long-term vegetation...
Predicted biomass of fine fuel for Altar Valley, Arizona, 2021 Predicted biomass of fine fuel for Altar Valley, Arizona, 2021
These data were compiled for the Altar Valley Conservation Alliance and the U. S. Fish and Wildlife Service to identify and quantify the spatial distribution of fine fuels in relation to wildfire management across jurisdictional boundaries. Objective(s) of our study were to map the 2021 annual distribution of the biomass (kg/ha) of fine fuels (grasses, shrubs, and forbs) for the whole of...
Hatchery-reared Roundtail Chub Data, Arizona USA Hatchery-reared Roundtail Chub Data, Arizona USA
These data were compiled as part of a larger study to evaluate post-stocking survival of hatchery-reared Roundtail Chub. We conducted a two year study (Dec. 2015 – Mar. 2017) in the upper Verde River at the Burnt Ranch stocking location near Paulden, Arizona. Young of year Roundtail Chub were acquired from the Arizona Research and Conservation Center in Cornville, Arizona. Passive...
