Data

Staff of USGS Science Centers in Region 7: Upper Colorado Basin collect a wide variety of natural resource data types including spatial, geologic, hydrologic, and biologic. Data included in USGS-series publications that are not publicly available in USGS databases are published in Data Releases. Short descriptions and links to Data Releases produced by Region 7 Science Centers are shown below.

A sequential selective dissolution method to quantify storage and stability of organic carbon associated with Al and Fe hydroxide phases

Stabilization of SOM (soil organic matter) is regulated in part by sorption and desorption reactions happening at mineral surfaces, as well as precipitation and dissolution of organo-metal complexes. Fe and Al hydroxides play a particularly significant role in SOM stabilization in soils due to their ubiquitous distribution and their highly reactive surface properties. Iron and Al hydroxides exist

Data on deltamethrin resistance in Oropsylla hirsuta fleas from black-tailed prairie dogs in South Dakota, USA, 2014-2015

Data on deltamethrin resistance in Oropsylla hirsuta fleas from black-tailed prairie dogs in Conata Basin, Buffalo Gap National Grassland and Badlands National Park, South Dakota, 2014-2015. Two data files are available, one from "Mortality trials" and another from "recovery trials". The data from "Mortality trials" includes information on bioassays in which fleas were subjected to deltamethrin in

Influence of wildfire and beetle-caused canopy mortality on water temperature regimes in cutthroat trout streams, Rocky Mountain National Park, CO

This dataset was collected to build on past and ongoing monitoring and research efforts within Colorado's Rocky Mountain National Park (RMNP). Specifically, the data were collected to test the hypothesis that reductions in canopy cover due to natural disturbances (i.e. wildfire and beetle kill) result in increases in water temperature, or the longitudinal thermal gradient of a stream. Data values

Capture-recapture, disease and covariate data for boreal toads from Blackrock Wyoming 2019

We investigated population dynamics in boreal toads relative to abiotic (fall temperatures and snowpack -the covariates provided here) and biotic (the abundance of another anuran host,data provide here) characteristics of the local environment at 6 sites in Wyoming, USA. We used capture-recapture data (i.e., 1 or 0, provided here) and a robust design multi-state model framework that incorporates d

Data on Flea Parasitism and Annual Re-encounters of Utah Prairie Dogs at 5 colonies on the Awapa Plateau, Utah, USA, 2013-2016

Data on flea parasitism and annual re-encounters of Utah prairie dogs at 5 colonies on the Awapa Plateau, Utah, USA, June-August 2013-2016. Utah prairie dogs were live-trapped and sampled on 5 colonies along an elevation gradient from 2,645 m to 2,873 m. Upon first capture each year, we anesthetized each prairie dog and fleas on its body and combed the prairie dog as thoroughly as possible for 30

Sample collection information and SNP data for Gunnison Sage-grouse across the species range generated in the Molecular Ecology Lab during 2015-2018

This dataset contains sample collection information and SNP genotypes for populations of Gunnison Sage-grouse across the species' range. This data was collected in order to examine patterns of adaptive genetic variation in Gunnison Sage-grouse. The data is archived in GenBank at the following URL https://www.ncbi.nlm.nih.gov/bioproject/517770.

Sample collection information and microsatellite data for Gunnison sage-grouse pre and post translocation

Maintenance of genetic diversity is important for conserving species, especially those with fragmented habitats and/or ranges. In the absence of natural dispersal, translocation can be used to achieve this goal. However, the long-term impacts from translocation can be expensive and difficult to evaluate. This dataset is used to evaluate genetic change as a result of translocation and represents sa

Influences of Potential Oil and Gas Development and Future Climate on Sage-Grouse Declines and Redistribution

This project represents the data used in "Influences of potential oil and gas development and future climate on sage-grouse declines and redistribution." The data sets describe greater sage-grouse (Centrocercus urophasianus) population change, summarized in different boundaries within the Wyoming Landscape Conservation Initiative (WLCI; southwestern Wyoming). Population changes were based on diff

Taxonomic composition of environmental DNA acquired by filtration from the St. Regis River, New York

Environmental DNA (eDNA) surveys have become important tools for monitoring aquatic biodiversity. Barcode sequencing of eDNA generates community profiles that, while potentially biased in both capture and amplification, can nonetheless yield high information content per unit cost. While factors affecting eDNA capture and amplification have been heavily studied, watershed-scale assessments of fish

Landscape inputs and simulation output for the LANDIS-II model in the Greater Yellowstone Ecosystem

This data release provides inputs needed to run the LANDIS-II landscape change model, NECN and Base Fire extensions for the Greater Yellowstone Ecosystem (GYE), USA, and simulation results that underlie figures and analysis in the accompanying publication. We ran LANDIS-II simulations for 112 years, from 1988-2100, using interpolated weather station data for 1988-2015 and downscaled output from 5

State-and-Transition Simulation Models of Buffelgrass in Saguaro National Park (2014-2044) to explore ecological uncertainties

This is a spatially-explicit state-and-transition simulation model of buffelgrass dynamics in Saguaro National Park, AZ. Buffelgrass is an invasive grass spreading in the park. The model represents uninvaded and invaded parts of the desert ecosystem and includes a connection to a fire behavior model. The model was built using the ST-Sim software platform linked to the FARSITE fire behavior model.

Terrestrial Development Index for the Western United States: 1-kilometer moving window

The Terrestrial Development Index (TDI) quantifies the level of development (urban, agriculture, energy and mineral extraction and transmission, and transportation) based on the surface disturbance footprint. TDI values range from 0 to 100% and represent the total percentage of land surface occupied by the development footprint within a 1-kilometer (km) radius moving window.
