In Support of the U.S. Fish and Wildlife Service 3-Bat Species Status Assessment: Predicted Wind Take Allocated to Hibernacula Each Year Under Current and Future Scenarios

Through the North American Bat Monitoring Program (NABat), United States Geological Survey (USGS) provided technical and science support to assist in U.S. Fish and Wildlife Services’ (USFWS) Species Status Assessment (“SSA”) for the northern long-eared bat (Myotis septentrionalis), little brown bat (Myotis lucifugus), and tri-colored bat (Perimyotis subflavus)....

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.

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).

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.
