Ecology of the Black-Footed Ferret and the Black-Tailed Prairie Dog
Research involving the black-footed 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 …

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
… and strychnine 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 …

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
The state 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 …

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 …

Life History and Ecology of the Black-Footed Ferret in the Wild
Twenty-one black-footed ferrets (Mustela nigripes) were observed at six different locations in southwest South Dakota between April 1966, and September 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 …

The Effects of Three Rodenticides on Nontarget Small Mammals and Invertebrates
… were 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 …

Burrowing Owl Distribution and Nest Site Selection in Western South Dakota
… of the Missouri 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 …
