They are closely related to squirrels, chipmunks, and marmots. "Cynomys mexicanus" originated about 230,000 years ago from a peripherally isolated population of the more widespread "Cynomys
Black-tailed prairie dog activities keep plant development in a suppressed vegetative state with higher nutritional qualities, herbivores, including red deer ("Cervus elaphus"), American bison, pronghorn ("Antilocapra americana"), and domestic cattle often prefer foraging in black-tailed prairie dog colonies. Animals that depend on herbaceous cover in sagebrush habitat, such as mule deer ("Odocoileus hemionus") and sage grouse ("Centrocercus" spp.), may be deterred by the decreased vegetative cover on black-tailed prairie dog colonies. For a list of vertebrate species associated with black-tailed prairie dog colonies, see. Biodiversity in shortgrass prairies may be at risk due to the reductions in distribution and occurrence of black-tailed prairie
