Data
Our interdisciplinary, integrated science teams develop various data sets in support of the USGS mission areas. This information then aids natural resource managers in decision making and support of the complex issues they face in today's world. The data and tools listed here are official USGS data releases.

grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases, version 1.2.0 grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases, version 1.2.0
Greater sage-grouse (Centrocercus urophasianus; hereafter referred to as sage-grouse) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the West (Hanser & Knick, 2011; Rowland et al., 2006). They occupy the sagebrush biome in western North America, extending east of the Sierra Nevada/Cascade Mountain ranges to the western regions of the Great...
Data on long-term flea control using fipronil grain bait with black-tailed prairie dogs, South Dakota, 2020-2022 Data on long-term flea control using fipronil grain bait with black-tailed prairie dogs, South Dakota, 2020-2022
We collected fleas from black-tailed prairie dogs (Cynomys ludovicianus) on Buffalo Gap National Grassland and Badlands National Park, South Dakota, 2020-2022. We anesthetized trapped prairie dogs (and their fleas) with isoflurane in induction chambers for processing. We combed each individual with a fine-tooth comb for 30 seconds to remove and count fleas. We released all animals, after...
Data on flea combing removals from black-tailed prairie dogs, Vermejo Park Ranch, New Mexico, 2011 Data on flea combing removals from black-tailed prairie dogs, Vermejo Park Ranch, New Mexico, 2011
We studied black-tailed prairie dogs and their fleas in the short-grass prairie of Vermejo Park Ranch, New Mexico, USA, June-August 2011. We live-trapped and sampled prairie dogs on 20 plots at 13 prairie dog colonies. Upon capture, we anesthetized each prairie dog (and its fleas) with isoflurane and combed the prairie dog as thoroughly as possible for ectoparasites (as described below)...
Data on flea larvae survival following exposure to black-tailed prairie dog scat, 2016-2018 Data on flea larvae survival following exposure to black-tailed prairie dog scat, 2016-2018
We collected fecal pellets from six black-tailed prairie dogs in captivity. Prairie dogs were provided free access to non-treated grain (oat groats) or fipronil-treated grain for 5 days. Two prairie dogs received non-treated grain and four prairie dogs received fipronil grain. During each day of the feeding trial, prairie dog fecal pellets were collected, stored in sealable plastic bags...
Data on flea control using FipBit fipronil bait pellets with black-tailed prairie dogs, South Dakota, 2020-2021 Data on flea control using FipBit fipronil bait pellets with black-tailed prairie dogs, South Dakota, 2020-2021
We live-trapped black-tailed prairie dogs on Buffalo Gap National Grassland, South Dakota, 2020-2021. We anesthetized trapped animals (and their fleas) with isoflurane in induction chambers for processing. We combed each individual with a fine-tooth comb for 30 seconds to remove and count fleas. The total flea count from an individual prairie dog was considered an index of flea abundance...
Feral burro detections from aerial infrared surveys collected in Sinbad Herd Management Area, Utah, USA, from 2015-2016 Feral burro detections from aerial infrared surveys collected in Sinbad Herd Management Area, Utah, USA, from 2015-2016
These data are detections of burros in the Sinbad Herd Management Area in central Utah made during aerial thermal infrared-based distance sampling surveys in December 2015 and May 2016. Burros were detected from a fixed wing aircraft using an infrared camera mounted on the underside of the aircraft. A monitor screen was inside the aircraft, connected to the camera so the observer could...
Diet of invasive Burmese Pythons (Python molorus bivittatus) in southern Florida, 1995-2020 Diet of invasive Burmese Pythons (Python molorus bivittatus) in southern Florida, 1995-2020
Digestive tract contents were identified to provide an account of Burmese python diet. Diet contents came from 1716 pythons collected by cooperators during 1995-2020 from public and private lands across southern Florida, primarily within the Greater Everglades Ecosystem. Burmese pythons consumed 76 species of fauna across three taxonomic classes (Aves, Mammalia, and Reptilia).
Serpentoviruses in free-ranging invasive pythons and native colubrids in southern Florida, United States, 2018-2020 Serpentoviruses in free-ranging invasive pythons and native colubrids in southern Florida, United States, 2018-2020
The presence of serpentoviruses in Burmese pythons (Python bivittatus) and native snakes were collected and compiled to characterize serpentovirus in wild free-ranging pythons and free-ranging native snakes within the invasive range of the pythons in southern Florida. Virus presence was tested in 318 pythons and 219 Native snakes, primarily within the Greater Everglades Ecosystem of...
State-and-Transition Simulation Models to explore post-fire habitat restoration in three greater sage-grouse (Centrocercus urophasianus) Priority Areas for Conservation, USA (2018-2068) State-and-Transition Simulation Models to explore post-fire habitat restoration in three greater sage-grouse (Centrocercus urophasianus) Priority Areas for Conservation, USA (2018-2068)
Wildfires are increasingly modifying wildlife habitat in the western United States and managers need ways to scope the pace and degree to which post-fire restoration actions can re-create habitat in dynamic landscapes. We simulated post-fire revegetation and greater sage-grouse (Centrocercus urophasianus) habitat restoration using a spatially explicit state-transition simulation model...
Voucher and metagenetic sequencing of DNA barcodes of wild-collected bees (Apoidea) from Iowa, USA Voucher and metagenetic sequencing of DNA barcodes of wild-collected bees (Apoidea) from Iowa, USA
High-throughput methods for identification of pollinator taxa are desirable to improve our understanding of pollinator distributions, population trends, and ecology. Genetic sequencing of taxonomically informative 'barcode' loci is one high-throughput strategy, which can be applied to individual specimens using Sanger technology and to complex mixtures using metabarcoding technology...
Sagebrush projections for greater sage-grouse core areas in Wyoming, USA, 2018-2100 Sagebrush projections for greater sage-grouse core areas in Wyoming, USA, 2018-2100
Sagebrush (Artemisia spp.) ecosystems provide critical habitat for the near-threatened Greater sage-grouse (Centrocercus urophasianus), and future loss of sagebrush habitat because of land use change and global climate change is of concern. We used a dynamic additive spatio-temporal model to estimate effects of climate (spring-summer temperatures and precipitation) on sagebrush cover...
Scenario Analysis of Management Alternatives for Free-roaming Horse Populations (Version 1.0.0) Scenario Analysis of Management Alternatives for Free-roaming Horse Populations (Version 1.0.0)
PopEquus is a predictive modeling tool to support decisions related to the management of free-roaming horse populations. It permits the simulation and comparison of how management alternatives influence horse population size and metrics associated with management. This repository uses R scripts with predictive functions from the PopEquus model to simulate how management alternatives (e.g
