Effects of Diethylstilbestrol on Reproduction in the Black-Tailed Prairie Dog
… on the reproductive cycle of the black-tailed prairie dog (Cynomys ludovicianus) and to test effectiveness of diethylstilbestrol as a reproductive inhibitor. Embryo body lengths from 10 pregnant females were compared to body lengths of 14 known day-old young to learn the peak breeding period …

Ecology of the Black-Footed Ferret and the Black-Tailed Prairie Dog
… ferret (Mustela nigripes) and black-tailed prairie dog (Cynomys ludovicianus) was conducted during 1968 and 1969. Eighteen prairie dog burrows were excavated in 1968 and 1969. Burrow systems ranged from 13 to 109 feet long and 3 to 14 feet deep. Fifteen of the burrows exhibited dome-shaped …

Establishing genetic and physiological baselines for the black-tailed prairie dog (Cynomys ludovicianus).
The black-tailed prairie dog (Cynomys ludovicianus) has experienced dramatic declines over much of its historical range due to habitat loss, plague, poisonings, and shootings. Many populations now occur as isolated genetic relicts. A multiple locus genetic profile was obtained using microsatellite …

Digestibility of Common Forage Plants and Energetic Requirements of the Black-Tailed Prairie Dog
<p>Black-tailed prairie dogs (Cynomys ludovicianus) assimilated 51.5 percent of the wheatgrass (Agropyron intermedium) they consumed; thus, they would have to consume 0.148 kcal · g-1 · day-l in order to obtain the 0.076 kcal · g-1 · day-1 they would require to maintain their weight. Prairie dogs …

Efficiency of Two Black-tailed Prairie Dog Rodenticides and Their Impacts on Non-target Bird Species
… without prebait were applied to black-tailed prairie dog (Cynomys ludovicianus) colonies in west-central South Dakota. Short-term (4 days later) and long-term (1 year later) poison efficiency and impact (short-term and long-term) on horned larks (Eromophila alpestrus) and other seed-eating …

Use of Natural Vegetative Barriers to Limit Black-Tailed Prairie Dog Town Expansion in Western South Dakota
Prairie dog (Cynomys ludovicianus) control has historically consisted of lethal methods to maintain, reduce, or eliminate populations. Non-lethal methods of control for prairie dogs are desired to meet changing management objectives. Use of naturally occurring buffer strips as vegetative barriers …

Evaluation of Barriers to Black-Tailed Prairie Dog (Cynomys ludovicianus) Colony Expansion, Bad River Ranches, South Dakota
… of South Dakota recently approved a black-tailed prairie dog (Cynomys ludovicianus) conservation and management plan (House Bill 1252 and Senate Bill 216, An Act to Mitigate the Impact of Prairie Dogs), which placed restrictions on prairie dog colonies that encroach upon private property where …

Effects of Black-tailed Prairie Dogs (Cynomys Iudovicianus) on Soil Erosion
… by fauna. Soil traps were implemented in a prairie dog town 14 miles NW of Killdeer, ND to measure and compare erosion rates within the prairie dog town to those of a control site comprised of natural prairie grasses and void of prairie dogs. Results from 81 days (May 31st-September 20th) …

Burrowing Owl Distribution and Nest Site Selection in Western South Dakota
… River, where it usually nests in black-tailed prairie dog (Cynomys ludovicianus) colonies. Information about the burrowing owl’s current range and habitat needs in South Dakota is necessary to maintain the species as a relatively common component of the state’s avifauna. During the summers of …

Key To Microscopic Fragments of Plant Tissue in Prairie Dog Stomachs and Food Habits of Prairie Dogs in South Dakota
… and construct a key of plants occurring on prairie dog towns in southwest South Dakota; (2) determine plant species eaten by prairie dogs by analyzing stomach and pellet samples; and (3) relate the availability of plant species and preference in the feeding habits of prairie dogs. Two …

Life History and Ecology of the Black-Footed Ferret in the Wild
… 1967. All observations were made on black-tailed prairie-dog (Cynomys ludovicianus) towns from 15 to 100 acres in size. Because of the proximity of towns inhabited by ferrets, it was possible that individual animals were observed in more than one location. Three litters of ferrets were studied. …

Breeding success, prey use, and mark-resight estimation of burrowing owls nesting on black-tailed prairie dog towns: plague affects a non-susceptible raptor
… We investigated the effects of plague, prairie dog town dynamics, and rainfall on burrowing owls (Athene cunicularia) nesting in black-tailed prairie dog (Cynomys ludovicianus) burrows in the shortgrass steppe of northern Colorado. We examined effects on prey use, nest density, and …

The Influence of Grazing Treatments on Density of Nesting Burrowing Owls on the Cheyenne River Sioux Reservation
… owl (Athene cunicularia) habitat in tall-grass prairies; however, limited research has been conducted in mixed-grass prairies regarding the relationship between burrowing owls and large herbivores. I examined the influence of grazing by bison (Bison bison) and cattle on burrowing owls on the …

Scampering in the City: Examining the Ecological and Social Viability of Black-Tailed Prairie Dogs (Cynomys ludovicianus) in Denver, Colorado
<p>The conservation of prairie dogs is highly contested due to the embedded view that they are pests. This research addressed the ecological and social viability of prairie dog colonies in Denver, Colorado. Remote sensing analysis was applied to identify potentially viable areas for urban prairie …

Ecology of the Coyote (Canis latrans) at Wind Cave National Park
Coyotes (Canis latrans) are common on the prairies that characterize Wind Cave National Park. Few studies have been conducted on the ecology of coyotes in South Dakota. With the potential effects coyotes may have on reintroduced endangered blackfooted ferrets (Mustela nigripes) to Wind Cave …

The Effects of Three Rodenticides on Nontarget Small Mammals and Invertebrates
… applied September 22-24, 1983 on 15 black-tailed prairie dog (Cynomys ludovicianus) towns. Immediate (September 1983) and long-term (September 1983 through August 1984) rodenticide efficacy and impacts on non-target wildlife species were evaluated. None of the 3 rodenticide treatments produced …

Prairie dogs, plants, and pollinators: tri-trophic interactions affect plant-insect floral visitor webs in shortgrass steppe
I investigated how black-tailed prairie dogs (Cynomys ludovicianus) altered pollinator habitat, specifically in terms of bare ground cover and floral resources, on northeastern Colorado's Pawnee National Grassland, in 2003 through 2005. I also measured changes in habitat utilization by insect …
