Spatially Explicit Modeling of Annual and Seasonal Habitat for Greater Sage-Grouse (Centrocercus urophasianus) in Nevada and Northeastern California - an Updated Decision-Support Tool for Management
Successful adaptive management hinges largely upon integrating new and improved sources of information as they become available. Updating management tools for greater sage-grouse ( Centrocercus urophasianus, hereafter referred to as sage-grouse) populations, which are indicators for the large-scale health of sagebrush ( Artemisia spp.) ecosystems in the Great Basin of North America, provide a time
Mean of the Top Ten Percent of NDVI Values in the Yuma Proving Ground during Monsoon Season, 1986-2011
This study uses growth in vegetation during the monsoon season measured from LANDSAT imagery as a proxy for measured rainfall. NDVI values from 26 years of pre- and post-monsoon season Landsat imagery were derived across Yuma Proving Ground (YPG) in southwestern Arizona, USA. The LANDSAT imagery (1986-2011) was downloaded from USGSs GlobeVis website (http://glovis.usgs.gov/). Change in NDVI was ca
Statistically-downscaled monthly historical (1901-2000) CRU TS 2.1 and projected future (2001-2099) CMIP3 A2 and A1B simulated temperature, precipitation, and sunshine data on a 30-second grid of the northwest United States and southwest Canada, version 1
This data set consists of monthly mean temperature (degrees C), total precipitation (mm), and possible sunshine (%) data statistically downscaled onto a 30-second grid of the northwest United States and southwest Canada. Historical climate data for 1901-2000 were developed from the CRU CL 1.0, CRU CL 2.0, and CRU TS 2.1 data sets (http://www.cru.uea.ac.uk/cru/data/hrg/). Projected future climate d
Bioclimatic variables calculated from statistically-downscaled historical (1901-2000) CRU TS 2.1 climate data and projected future (2001-2099) CMIP3 A2 and A1B simulated climate data on a 30-second grid of the northwest United States and southwest Canada,

LPJ biomes (30-year mean) simulated using monthly historical (1901-2000) CRU TS 2.1 climate data and projected future (2001-2099) CMIP3 A2 and A1B simulated climate data on a 30-second grid of the northwest United States and southwest Canada, version 1.0
This data set consists of biomes (30-year mean) simulated using LPJ, a dynamic global vegetation model (Sitch et al. 2003, Global Change Biology 9:161-185), for a 30-second grid of the northwest United States and southwest Canada. Shafer et al. (2015, PLoS ONE 10: e0138759) describe the methods used to create the biome data. LPJ was run for 1901-2000 using historical climate data developed from th
Periphyton (1993-2011) and Water Quality (2014) Data for ET&C Article Entitled Spatial and Temporal Variation in Microcystins Occurrence in Wadeable Streams in the Southeastern USA
Spatial reconnaissance of fluvial microcystins (MC) concentrations and select water-quality parameters, including nutrients and periphyton biomass, in 75 wadeable streams in the Piedmont region of the southeastern USA during 2014. Data set includes only those data specifically discussed in the associated journal article:

Stable Isotope Data from Diets and Tissues of Captive Bears Fed Experimental Diets
This dataset contains stable isotope incorporation and discrimination results for several sets of feeding experiments with captive brown and polar bears. Experiments were designed to determine the effects of dietary lipid content and fasting behavior on discrimination in blood, hair, and fat. Data are divided into three components of the study: one to estimate isotopic discrimination with varyin
Long-term effects of wildfire on greater sage-grouse - integrating population and ecosystem concepts for management in the Great Basin
Greater sage-grouse ( Centrocercus urophasianus; hereinafter, sage-grouse) are a sagebrush obligate species that has declined concomitantly with the loss and fragmentation of sagebrush ecosystems across most of its geographical range. The species has been considered for listing under the federal Endangered Species Act multiple times, and was most recently ruled to not warrant protection as of Sept
Phytoplankton data for Cheney Reservoir near Cheney, Kansas, June 2001 through November 2015
This U.S. Geological Survey (USGS) Data Release provides phytoplankton data collected from Cheney Reservoir, Kansas, during June 2001 through November 2015. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the open data requirements as a way to make scientific products associated with USGS research eff
Streamflow and fish community diversity data for use in developing ecological limit functions for the Cumberland Plateau, northeastern Middle Tennessee and southwestern Kentucky, 2015
This geospatial dataset includes one point feature class file and associated FGDC-compliant metadata representing datasets to support development of ecological limit functions for the Cumberland Plateau in northeastern Middle Tennessee and southeastern Kentucky. Information contained within the dataset represents values of basin characteristics, estimates of streamflow characteristics, measures o
A Century of Landscape Disturbance and Urbanization of the San Francisco Bay Region affects the Present-day Genetic Diversity of the California Ridgways Rail (Rallus obsoletus obsoletus).
Fragmentation and loss of natural habitat have important consequences for wild populations. Reductions in population size, density and connectivity can disrupt the distribution of genetic diversity within species and negatively impact long-term viability and resilience to environmental change. Genetic assessments of population structure, diversity and gene flow can provide important insights into
Estimates of pathogen exposure predict varying transmission likelihood: Host contact and shedding patterns may clarify disease dynamics in desert tortoises Gopherus agassizii
These datasets (S1-S4) document the transmission of a bacterial pathogen (Mycoplasma agassizii) between desert tortoises (Gopherus agassizii). The desert tortoises were experimentally introduced in captivity and were used to create and compare models predicting transmission probability given data on the hosts and their interactions. Datasets S1 & S2 include variables describing the individual tort
