Genetic variability within and among populations of the black- tailed prairie dog ( Cynomys ludovicianus New Mexico).

In eastern New Mexico, significant genetic differentiation was found for Cynomys ludovicianus from populations in close proximity (5-15 km) as well as for those from distant parts of their range. The degree of local differentiation was greater than that among regions separated by major geographical barriers. Significant heterogeneity of allele frequencies was found for prairie dogs from different wards (portions of a population separated by unsuitable habitat) within a population, as well as for those from different coteries (harem groups) within the wards. The social behavior of prairie dogs has resulted in genetic differentiation over very small distances and rapid inbreeding and genetic drift within the social groups. -from Author
