Data were collected in 2017 by researchers at the USGS, USDA-ARS, and University of Wyoming on the food webs of plants, prairie dogs, arthropods, and birds in the Thunder Basin National Grassland. Data were collected from 87 sites in order to parameterize a structural equation model linking prairie dog impacts to changes in vegetation, arthropods, and birds. Abiotic information such as topographic wetness index, terrain roughness, and soil characteristics were estimated at the same set of plots in order to account for abiotic variation across the landscape.
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 and after FipBit treatments. We anesthetized each prairie dog with isoflurane and combed it thoroughly for 30 seconds to dislodge fleas, which fell into a plastic bin. Fleas were counted and allowed to recover from anesthesia and placed back on prairie dogs, to minimize any removal effect. We weighed prairie dogs with...

Data on body condition and reproduction 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. We recorded the age (juvenile/adult) and mass (nearest 5 grams) of each prairie dog and marked its ears and body with metal tags and passive integrated transponders, respectively, for permanent identification. We measured each prairie dog's right hind foot length (nearest millimeter). We indexed each adult prairie dog's body condition as the ratio between its mass and hind-foot length. Prairie dogs were allowed to recover from anesthesia and released at their trapping locations. We indexed prairie dog reproduction, by colony...

Data on the degree and duration of deltamethrin flea control on prairie dog colonies, with 3 prairie dog species at 6 sites across 3 US states. Fleas were combed (COMB) from live-trapped prairie dogs or swabbed (SWAB) from prairie dog burrows on non-treated (Non) sites and nearby sites treated with deltamethrin dust for flea control (Dusted). Each line of data is from an individual prairie dog or burrow. The first set of data, Shortterm BACI, includes data from before-after-control-impact (BACI) experiments comparing the abundance of fleas on prairie dogs at paired non-treated and treated sites in 2 time intervals: before treatments (Before) and 2 to 65 days after treatments (After). The second set of data, Moderate...
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% deltamethrin dust and 5 sites with host-fed 0.005% fipronil grain. Three non-treated sites functioned as experimental baselines. We collected ectoparasites before treatments (June-July 2018) and after treatments (August-October 2018, June-July 2019). We combed ectoparasites from live-trapped, anesthetized prairie dogs. Trapping on treated and non-treated sites occurred simultaneously or nearly simultaneously in each year. Detected ectoparasites were counted and placed back on the prairie dogs from which they were collected to...
Concern over the decline of grassland birds has spurred efforts to increase understanding of grassland bird-habitat relationships. Previous studies have suggested that black-tailed prairie dogs (Cynomys ludovicianus) provide important habitat for shortgrass prairie avifauna, such as mountain plover (Charadrius montanus) and western burrowing owl (Athene cunicularia hypugaea), although such studies are lacking in Colorado (USA). We used methods to estimate occupancy (psi) of mountain plover and burrowing owl on prairie dog colonies and other shortgrass prairie habitats in eastern Colorado. Mountain plover occupancy was higher on prairie dog colonies (psi = 0.50, 95% CI = 0.36-0.64) than on grassland (psi = 0.07,...
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 Science Center, and colleagues. Data were collected on paired plots. Each pair included a plot treated annually with deltamethrin dust for flea control and plague mitigation and a plot left untreated as baselines. Paired plots had similar ecological features on the same (split) or nearby (separate) colonies. One plot within...

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 Petri dishes. In 2014, fleas were collected from colonies of black-tailed prairie dogs that had been treated with a deltamethrin-containing dust since 2005 (Dusted) and colonies that had never been treated with deltamethrin (Not Dusted). The fleas were placed in Petri dishes with deltamethrin. All fleas were alive at the...

Oral sylvatic plague vaccine baits (SPV) and placebo baits, each containing Rhodamine B dye biomarker, were distributed once annually from 2013-2016 on treated and non-treated paired plots from 2013-2016. Black-tailed prairie dogs (BTPD) were live-trapped and permanently marked with passive integrated transponders and ear tags on 4 pairs of plots each year from 2013-2017 to provide capture/recapture data. Capture locations were recorded using global positioning systems. Hair and whisker samples were pulled from each prairie dog to assess bait uptake (i.e. consumption) using a florescent microscope to inspect the samples for Rhodamine B florescence. The first data set (CMR_MOVEMENT_DATA.csv) lists distances (meters)...

Data on prairie dog densities, flea abundance on prairie dogs, and plague epizootics in Montana and Utah, USA, 2003-2005. Prairie dog species (PDspecies in the data file) 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 Science Center, and colleagues. We used summertime visual counts as an index to PD densities (Pddensity in the data file). For each plot, we counted PDs using binoculars and/or spotting scopes from a single location outside the plot that gave the best view of the...

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 s to collect fleas. We recorded the age (juvenile/adult), sex, and mass (nearest 5 g) of each prairie dog and marked its ears and body with metal tags and passive integrated transponders, respectively, for permanent identification. We indexed each prairie dog's body condition as the ratio between its weight and hind-foot...

Mean flea counts from prairie dogs and their burrows in Utah (2000), New Mexico (2010–2012), and Montana (2016, 2019). Prairie dogs were live-trapped, anesthetized with isoflurane, and combed thoroughly for 30 or 45 seconds to remove and count fleas. Prairie dogs were allowed to recover from anesthesia and released at their trapping locations. Randomly selected prairie dog burrows were swabbed for fleas using a plumber’s snake to insert a white flannel-cloth as deep as possible into each tunnel; the cable was shook ~30 seconds, and the cloth was removed from the burrow and quickly sealed in a re-sealable zipper storage bag. Fleas were later removed from swabs and counted. Mean flea counts were calculated for each...
Long-term research with marked individuals shows that black-tailed, Gunnison's, and Utah prairie dogs (Sciuridae: Cynomys ludovicianus, C. gunnisoni, and C. parvidens) all reproduce slowly, despite claims of ranchers and early naturalists. Five factors are responsible for the slow reproduction. First, survivorship in the 1st year is <60% for all 3 species, and it remains low in later years. Second, even under optimal conditions, females of all 3 species produce only 1 litter/year. Third, the percentage of males that copulate as yearlings is only 6%, 24%, and 49% for black-tailed, Gunnison's, and Utah prairie dogs, respectively. The percentage of females that copulate as yearlings is only 35% for black-tailed prairie...

Our study was conducted in 2005 on 3 colonies of black-tailed prairie dogs on lands in Phillips County, Montana administered by the Bureau of Land Management and in 2009 on a colony of black-tailed prairie dogs on Buffalo Gap National Grassland, Pennington County, South Dakota managed by U.S. Forest Service. We live-trapped black-tailed prairie dogs in daylight with wire mesh traps and marked their ears with numbered tags for individual identification. We weighed each individual to the nearest gram and collected Universal Transverse Mercator coordinates of their trapping locations over time. In Montana, trapping began on 15 June 2005 and ended on 1 October 2005. In South Dakota, trapping was conducted during 7 June...

Data on the efficacy of deltamethrin flea control with small rodents on prairie dog colonies in Montana and Utah, 2001-2004. Data were collected on 12 colonies of 3 prairie dog (PD) species at 5 sites in Montana and Utah. PD species included black-tailed PDs (Cynomys ludovicianus, BTPDs), Utah PDs (C. parvidens, UPDs), and white-tailed PDs (C. leucurus, WTPDs). Sample sizes from 6 small rodents (Species in the data file) were sufficient for analysis: deer mice, grasshopper mice, Ord’s kangaroo rats, hispid pocket mice, dark kangaroo mice, and sagebrush voles. Efficacy of deltamethrin was assessed by combing fleas from live-trapped, anesthetized rodents on paired dusted and non-dusted plots (binary variable for DeltamethrinDust...
This data was used to investigate the invasion of a non-native disease, plague, to a keystone species, prairie dogs, in Conata Basin, South Dakota, United States. We documented the resulting extent of fragmentation and habitat loss in western grasslands using colony boundaries mapped by the USFS every one to three years from 1993 - 2015. Specifically, we assessed how the arrival of plague in 2008, affected the size, shape, and aggregation of prairie dog colonies, an animal species known to be highly susceptible to plague. As expected the colony complex and the patches in colonies became smaller and more fragmented after the arrival of plague; the total area of each colony and the average area per patch within a...

Data on the occurrence of plague epizootics in colonies of black-tailed prairie dogs, Pawnee National Grassland, Colorado 1982-2005. Data are derived from annual prairie dog surveys conducted by staff of the Pawnee National Grassland, U.S. Forest Service. The data includes information on the year of sampling, colony identification, UTM coordinates of colony centroids, weather (precipitation and temperature), colony area, soil moisture-holding capacity, connectivity among colonies, and the occurrence of plague epizootics. Data provided by M.F. Antolin and L.T. Savage, Colorado State University, supported by the National Science Foundation (DEB-9616044, DEB-0217631, DEB-0823405, EF-0327052), the U.S. Forest Service,...
Body mass is sexually dimorphic and varies seasonally for all 5 species of prairie dogs (Sciuridae: Cynomys), as shown by data from live individuals over a period of 28 years (1974–2001; n = 16,447 body masses). Sexual dimorphism (i.e., body mass of males as percentage of body mass of females) during the breeding season is 105% for black-tailed prairie dogs, 127% for Utah prairie dogs, 131% for Gunnison's prairie dogs, and 136% for white-tailed prairie dogs. Sexual dimorphism is minimal at the end of the breeding season, when exhausted males are thin and early-breeding females are heavy with pregnancy. Sexual dimorphism is maximal at weaning, when rested, well-fed males are heavy and females are emaciated from...
