Genetic Variation and Structure in Contrasting Geographic Distributions: Widespread Versus Restricted Black-Tailed Prairie Dogs (Subgenus Cynomys).
Species of restricted distribution are considered more vulnerable to extinction because of low levels of genetic variation relative to widespread taxa. Species of the subgenus Cynomys are an excellent system to compare genetic variation and degree of genetic structure in contrasting geographic distributions. We assessed levels of genetic variation, genetic structure, and genetic differentiation...
متن کاملGeographic variation in rodent-flea relationships in the presence of black-tailed prairie dog colonies.
We characterized the relationship between fleas and their rodent hosts in the presence of prairie dog colonies and compared them to adjacent assemblages away from colonies. We evaluated the rodent-flea relationship by quantifying prevalence, probability of infestation, flea load, and intensity of fleas on rodents. As prairie dog burrows provide refugia for fleas, we hypothesized that prevalence...
متن کاملDisease limits populations: plague and black-tailed prairie dogs.
Plague is an exotic vector-borne disease caused by the bacterium Yersinia pestis that causes mortality rates approaching 100% in black-tailed prairie dogs (Cynomys ludovicianus). We mapped the perimeter of the active portions of black-tailed prairie dog colonies annually between 1999 and 2005 at four prairie dog colony complexes in areas with a history of plague, as well as at two complexes tha...
متن کاملEffects of Black-Tailed Prairie Dogs on Reptiles and Amphibians in Kansas Shortgrass Prairie
Species diversity and abundance of reptiles and amphibians were measured on and off black-tailed prairie dog (Cynomys ludovicianus) colonies to determine the extent to which herpetological species composition in a shortgrass prairie ecosystem is affected by presence of blacktailed prairie dog colonies. Ten species of reptiles and 3 species of amphibians were captured. Total amphibian and reptil...
متن کاملRodent Communities in Active and Inactive Colonies of Black-tailed Prairie Dogs in Shortgrass Steppe
Black-tailed prairie dogs (Cynomys ludovicianus) alter shortgrass-steppe landscapes in ways that are expected to affect other mammals. I sampled rodent populations at 31 sites on the Pawnee National Grasslands, Colorado, including 18 active colonies, 6 colonies that had been unoccupied for .6 years (inactive), and 7 grassland sites without prairie dogs (controls). Rodents were livetrapped for 4...
