Flea abundance on black-tailed prairie dogs (Cynomys
ludovicianus) increases during plague epizootics.
Species assessment for black-tailed prairie dog (Cynomys
ludoviciantes) in Wyoming.
Black-tailed prairie dogs (Cynomys
ludovicianus) and pocket gophers (Geomys bursarius), rodents that live in large colonies on the prairies of North America, provide one of the classic examples of mammals that structure the landscape, alter the species composition of the vegetation, and so facilitate other herbivores (Huntly and Inouye 1988, Whicker and Detling 1988a,b).
Data on prairie dogs (Cynomys
) provide evidence of plague-induced variation in populations.

Despite their limited range of southwestern Utah, which includes Bryce Canyon National Park, Cynomys
parvidens numbered about 95,000 individuals in the 1920s.
Due to loss of prairie habitat, species such as the white-tailed jackrabbit (Lepus townsendii), black-tailed prairie dog (Cynomys
ludovicianus), northern pocket gopher (Thomomys talpoides), plains pocket mouse (Perognat has flavescens), and plains harvest mouse (Reithrodontomys montanus) may be absent from parts of their historical ranges.
The evolution of coloniality in white-tailed and black-tailed prairie dogs (Sciuridae: Cynomys
leucurus and Cynomys
Ritchie (1999) has demonstrated this effect in isolated colonies of a generalist grazing herbivore, the Utah prairie dog (Cynomys
parvidens); local extinction rates decline dramatically with increasing food plant species diversity.
