Black-Tailed Prairie Dog Colony Dynamics in South Dakota Over a 10-Year Period
Between 1968 and 1978, aerial photography was used to monitor distribution of blacktailed prairie dog (Cynomys ludovicianus) colonies on a 400-square mile area in South Dakota, including parts of Buffalo Gap National Grassland, Pine Ridge Indian Reservation, and Badlands National Monument (now Badlands National Park). Aerial photographs were taken of the study area in 1968 and annually from 197...
متن کاملFasting Biochemistry of Representative Spontaneous and Facultative Hibernators : The White-Tailed Prairie Dog and the Black-Tailed Prairie Dog
The white-tailed prairie dog is a spontaneous hibernator that enters an anorexic state followed by torpor in early fall. The black-tailed prairie dog is a facultative hibernator that enters torpor only when deprived offood and water in the winter. The physiological state of hibernation is similar to a Phase II euthermic fast characterized by elevated fat catabolism, increased blood ketone bodie...
متن کاملNest Predation on Black-Tailed Prairie Dog Colonies
Nest predation is the principal cause of mortaliv for many grassland birds. Predation rates may be higher on prairie dog colonies because they may have less available nesting cover and may increase predator abundance. We compared 14-day nest predation rates for 1,764 artificial nests on 102 black-tailed prairie dog (Cynovnys ludovicianus) colonies and their paired off-colony sites (similar habi...
متن کاملResistance to plague among black-tailed prairie dog populations.
In some rodent species frequently exposed to plague outbreaks caused by Yersinia pestis, resistance to the disease has evolved as a population trait. As a first step in determining if plague resistance has developed in black-tailed prairie dogs (Cynomys ludovicianus), animals captured from colonies in a plague-free region (South Dakota) and two plague-endemic regions (Colorado and Texas) were c...
متن کاملAttributes of Black-Tailed Prairie Dog Colonies in Northcentral Montana
We examined several characteristics of black-tailed prairie dog (Cynomys ludovicianus) colonies in Phillips County, Montana, including slope, aspect, soils, land tenure, and distance from roads using a geographic information system (GIs). Colonies exhibited significantly smaller slopes, but not significantly different aspects than did randomly located polygons. In addition, colonies were more p...
