Data and Tools

Our interdisciplinary, integrated science teams develop various data sets and tools in support of the USGS mission areas. These tools then aid natural resource managers in decision making and support of the complex issues they face in today's world.

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).

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.

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.

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.

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.

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.

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.

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.

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.

Distribution of a freshwater mussel assemblage in Nebraska, Kansas, and Oklahoma

The purpose of this data release and associated data series (Carr and Fancher, 2021) was to compile occurrence records and map the distribution of a freshwater mussel assemblage for the Bureau of Land Management Rapid Ecoregional Assessment for the Southern Great Plains.

Predicted (1989-2015) and forecasted (2015-2114) estimates for rate of change and recovery of sagebrush (Artemisia spp.) following energy development in southwestern Wyoming, USA (ver. 2.0, January 2021)

In 'Predicted (1989-2015) and forecasted (2015-2114) rate of change and recovery of sagebrush (Artemisia spp.) following energy development in southwestern Wyoming, USA (ver. 2.0, January 2021)', we provide spatially- and temporally-explicit maps of predictions for the rate of change and time to recovery and percent recovery of sagebrush cover after 100 years (Monroe et al. 2020).

Brown Treesnake Mortality Habitat Management Unit Guam 2019

The dataset contains 16 columns of data collected on invasive Brown Treesnakes (Boiga irregularis) at a study site known as the Habitat Management Unit (HMU) in northern Guam. Snakes were fitted with radio-transmitters and teams of 2-4 biologist listened for signals from transmitters every seven days to determine if snakes were alive or dead.
