Data on finite population change for 3 species of prairie dogs in Montana and Utah, USA, 2000-2005 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...
Data on deltamethrin resistance in Oropsylla hirsuta fleas from black-tailed prairie dogs in South Dakota, USA, 2014-2015 Data on deltamethrin resistance in Oropsylla hirsuta fleas from black-tailed prairie dogs in South Dakota, USA, 2014-2015
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...
Data on Flea Parasitism and Annual Re-encounters of Utah Prairie Dogs at 5 colonies on the Awapa Plateau, Utah, USA, 2013-2016 Data on Flea Parasitism and Annual Re-encounters of Utah Prairie Dogs at 5 colonies on the Awapa Plateau, Utah, USA, 2013-2016
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...
Grooming behaviors of black-tailed prairie dogs in Phillips County, Montana, 2006 Grooming behaviors of black-tailed prairie dogs in Phillips County, Montana, 2006
Data on factors that affect the grooming behaviors of black-tailed prairie dogs in Phillips County, Montana, 2006. Each line of data presents information for a focal observation of a single black-tailed prairie dog. The data includes information on the date of each observation, the approximate coordinates of sites, the time of each observation, indexed wind speed, indexed temperature...
Occurrence of plague epizootics in colonies of black-tailed prairie dogs, Pawnee National Grassland, Colorado, 1982-2005 Occurrence of plague epizootics in colonies of black-tailed prairie dogs, Pawnee National Grassland, Colorado, 1982-2005
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...

Plague mitigation for prairie dog and black-footed ferret conservation: Degree and duration of flea control with 0.005% fipronil grain bait Plague mitigation for prairie dog and black-footed ferret conservation: Degree and duration of flea control with 0.005% fipronil grain bait
Sylvatic plague, a primarily flea-borne zoonosis, is a significant threat to prairie dogs (Cynomys spp., PDs) and their specialized predators, endangered black-footed ferrets (Mustela nigripes, BFFs). Host-fed fipronil baits have proven effective in controlling fleas on PDs for the purposes of plague mitigation and BFF conservation. Currently, annual treatments are the norm. We tested...

Estimating parasite infrapopulation size given imperfect detection: Proof-of-concept with ectoparasitic fleas on prairie dogs Estimating parasite infrapopulation size given imperfect detection: Proof-of-concept with ectoparasitic fleas on prairie dogs
Parasite infrapopulation size - the population of parasites affecting a single host - is a central metric in parasitology. However, parasites are small and elusive such that imperfect detection is expected. Repeated sampling of parasites during primary sampling occasions (e.g., each host capture) informs the detection process. Here, we estimate flea (Siphonaptera) infrapopulation size on...

Lethal effects on flea larvae of fipronil in host feces: Potential benefits for plague mitigation Lethal effects on flea larvae of fipronil in host feces: Potential benefits for plague mitigation
Plague, caused by the bacterium Yersinia pestis, is a zoonotic disease of mammalian hosts and flea vectors. Fipronil baits have been used to suppress adult fleas for plague mitigation. The degree and duration of flea control may increase if fipronil also kills other stages in the flea life cycle. We fed grain treated with 0.005% fipronil by weight, or nontreated grain, to black-tailed...

Flea control on prairie dogs (Cynomys spp.) with fipronil bait pellets: Potential plague mitigation tool for rapid field application and wildlife conservation Flea control on prairie dogs (Cynomys spp.) with fipronil bait pellets: Potential plague mitigation tool for rapid field application and wildlife conservation
Sylvatic plague is a widespread, primarily flea-vectored disease in western North America. Because plague is highly lethal to endangered black-footed ferrets (Mustela nigripes, BFFs) and the prairie dogs (Cynomys spp., PDs) on which BFFs depend for habitat and prey, minimizing the impacts of plague is a priority at BFF reintroduction sites. We developed a new, flour-based bait pellet...

Exploring and mitigating plague for One Health purposes Exploring and mitigating plague for One Health purposes
Purpose of Review In 2020, the Appropriations Committee for the U.S. House of Representatives directed the CDC to develop a national One Health framework to combat zoonotic diseases, including sylvatic plague, which is caused by the flea-borne bacterium Yersinia pestis. This review builds upon that multisectoral objective. We aim to increase awareness of Y. pestis and to highlight...

Plague and trace metals in natural systems Plague and trace metals in natural systems
All pathogenic organisms are exposed to abiotic influences such as the microclimates and chemical constituents of their environments. Even those pathogens that exist primarily within their hosts or vectors can be influenced directly or indirectly. Yersinia pestis, the flea-borne bacterium causing plague, is influenced by climate and its survival in soil suggests a potentially strong...
