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.

Data on the Efficacy of Five Pulicides as Tools for Suppressing Fleas on Black-tailed Prairie Dogs, South Dakota, 2015-2017
Data on the efficacy of 5 pulicides as tools for suppressing fleas on black-tailed prairie dogs in Buffalo Gap National Grassland, South Dakota, 2015-2017. Fleas were collected from live-trapped prairie dogs on non-treated (CONTROL) sites and nearby sites treated with pulicides for flea control. Data are from 3 prairie dog colonies (South Exclosure, Cutbank, and Big Foot). We tested the following
Data on finite population change for 3 species of prairie dogs in Montana and Utah, USA, 2000-2005
Data on annual population change for prairie dogs in Montana and Utah, USA, 2000-2005. Prairie dog species included black-tailed prairie dogs (PDs) (BTPD, Cynomys ludovicianus) in north-central Montana, white-tailed PDs (WTPD, Cynomys leucurus) in eastern Utah, and Utah PDs (UPD, Cynomys parvidens) in southwestern Utah. Field research was completed by the U.S. Geological Survey, Fort Collins Scien
Flea abundance and body condition data for black-tailed prairie dogs on sites treated and not treated with "FipBit" fipronil pellets, South Dakota, 2018-2020
Flea abundance and body condition data for black-tailed prairie dogs on sites treated and not treated with "FipBit" fipronil pellets. We sampled prairie dogs at Conata Basin, Buffalo Gap National Grassland, and Badlands National Park, South Dakota, USA. We sampled fleas from live-trapped prairie dogs during June-October 2018, May-October 2019, and July-August 2020. Prairie dogs were sampled before
Monitoring mortality of brown treesnakes fed an oral toxicant (acetaminophen) in an external bait placement dosing technique in the laboratory, 2017
Accidentally introduced to Guam, the brown treesnake (BTS) has extirpated nearly all native forest birds and imposed cost millions of dollars in economic damages annually. Acetaminophen is a safe and effective oral toxicant for invasive BTS, and an automated aerial delivery system (ADS) has been developed for landscape-scale distribution and snake suppression. An 80 milligram dose has proven 100%
Chorus frog density and population growth, Cameron Pass, Colorado, 1986-2020
We investigated population dynamics in chorus frogs (Pseudacris maculata) relative to extrinsic (air temperatures and snowpack) and intrinsic (density dependence) characteristics at 2 sites in Colorado, USA. We used capture-mark-recapture (cmr) data (i.e., 1 or 0, provided here) and a Bayesian model framework to assess our a priori hypotheses about interactions among covariates and chorus frog sur
Data for a lab study of the effects of diet variability on the interactions between a Lepidopteran herbivore and its parasitoid
Data were collected from two laboratory rearing experiments conducted in 2018 of Trichoplusia ni caterpillars that had been parasitized by Copidosoma floridanum parasitoids. In the first experiment, parasitized caterpillars were fed artificial diets spiked with increasing concentrations of the phytochemical xanthotoxin in order to assess the effect of xanthotoxin on parasitoid success. In the seco
Visual Surveys and Morphometrics of Brown Treesnakes in Mariana Swiftlets caves on Guam
Visual survey data for brown treesnakes from caves with and without swiftlets. Each record (line) represents the snake sightings that occurred during a block of time, typically 1 hour at one site by searcher(s) during one search (i.e. one date). Snakes removed from caves and adjacent areas during visual surveys were then necropsied. Each record (line) represents necropsy results for a given indivi
Salvator merianae trapping in Georgia, USA
Argentine Giant Tegu lizard (Salvator merianae) trap effort and count data collected in southern Georgia, USA in 2019. Non-target species associated with the traps were also documented, as were type of bait used and condition of the traps during trap checks.
Presence of erosional features and cover of grasses, forbs, and bare ground on fields enrolled in grassland, wetland, and wildlife practices of the Conservation Reserve Program in the central and western United States from 2016 to 2018
Data included in this data set are from in-field and edge-of-field surveys that recorded the presence of erosional features and cover of vegetation and bare ground on 1786 Conservation Reserve Program fields across three types of conservation practices (grassland, wetland, and wildlife). Field sampling data were recorded across six US Department of Agriculture Farm Production Regions (Corn belt, L
Data on the effects of deltamethrin and fipronil on black-tailed prairie dog ectoparasites, South Dakota, USA, 2018-2019
Data were collected to investigate effects of deltamethrin and fipronil on ectoparasites from black-tailed prairie dogs in South Dakota, USA. In late-July 2018, we treated 3 sites with 0.05 percent deltamethrin dust and 5 sites with host-fed 0.005 percent fipronil grain. Three non-treated sites functioned as experimental baselines. We collected ectoparasites before treatments (June-July 2018) and
Lek Disturbance Buffer Analysis data, Western Colorado, Derived from Gunnison Sage Grouse Location Data 2010 - 2014
This data release consists of three files (Crawford_and_WGB_Location_Data_S1.csv, Lek_Dist_S2.csv, and Home_Range_Area_S3.csv). The first data set represents specifics about each GPS location representing temporal and spatial relationships used in our analysis including the Month, day and year and local time each location was collected along with distance between locations, elevation in meters, d
Genetic variation in hoary bats (Lasiurus cinereus) assessed from archived samples
Hoary bats are among the bat species most commonly killed by turbine strikes in the midwestern United States. The impact of this mortality on species census size is not understood, due in part to the difficulty of estimating population size for this highly migratory and elusive species. Genetic effective population size (Ne) could provide an index of census population size if other factors affecti
