Reproduction and behavior of the Mexican prairie dog (Cynomys mexicanus). Although it has not been documented in Mexican prairie dogs, some Cynomys species stand upright in an alert posture (i.e., posting), which allows them to see predators more easily and makes them visible to other prairie dogs in the local area. American Midland Naturalist, 92/1: 130-145. Prairie dogs have one of the most sophisticated languages in the animal world—a system of high-pitched yips and barks—and can run up to 35 miles per hour (56 kilometres per hour). Because Mexican prairie dogs are a keystone species, declining populations are resulting in a domino effect, which has caused other species to be threatened or endangered. Due to the underground structures in which many prairie dogs live, it is difficult to accurately survey populations. Adults range in mass from 300 to 900 grams in the spring, and 500 to 2000 grams in the fall. Contributor Galleries Convergent in birds. A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. Treatment as an agricultural pest has led to its status as an endangered species. While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control. Neonates weigh between 15 and 20 g, and the mean mass of juveniles upon emergence from their burrow varies inversely with litter size. (Ceballos-G. and Wilson, 1985; Feldhamer, et al., 2003; Slobodchikoff, et al., 2009), Mexican prairie dogs are polygynous and commonly form groups of females that reside within their mother's territory resulting in large clans or colonies (i.e., matrilocal harems). These flea species, both of which have been found on Mexican prairie dogs, can be transmitted by other rodents or predators.

Treatment as an agricultural pest has led to its status as an endangered species. (Hoogland, 1995; Rioja-Paradela, et al., 1998), The percentage of juveniles that survive at least one year is directly correlated with body mass upon emergence from the burrow. (Feldhamer, et al., 2003; Hoogland, 1995; Mellado, et al., 2005b; Mellink and Madrigal, 1993; Slobodchikoff, et al., 2009), In the same way that the burrows of Mexican prairie dogs have positive impacts, they also cause an increase in calcification of surface soil which accelerates the process of erosion due to the increased amount of bare land. The Mexican prairie dog Cynomys mexicanus is an endemic burrowing rodent with a restricted distribution. the region of the earth that surrounds the equator, from 23.5 degrees north to 23.5 degrees south.

(Ceballos-G. and Wilson, 1985; Feldhamer, et al., 2003; Pizzimenti and McClenaghan Jr., 1974), Mexican prairie dogs have large auditory bullae, which allow them to hear sounds ranging from 29 to 26,000 Hz, with peak hearing occurring between 500 and 4000 Hz. Mexican prairie dogs excavate exploratory burrows in rocky, sandy, and clay soils; however, very sandy soils are unfavorable for burrowing. Disclaimer: Sometimes, spotted ground squirrels or burrowing owls share the burrow with its rightful owners. Teats become elongate and swollen during late pregnancy and remain so until weaning is complete. Wild Mammals of North America: Biology, Management, and Conservation. 2010. Individuals can grow to 341.09 mm. Farmers also believe that burrows cause livestock to stumble into openings and break their legs, although fractures of this type rarely occur. If a coterie contains two breeding males, the heavier male holds dominance over the other, although two breeding males of the same size show no difference in dominance behavior. Decreased cover allows for earlier predator detection, and living in large social groups allows individuals to spend more time feeding rather than constantly scanning for predators. Males are primarily responsible for territorial defense. at www.iucnredlist.org. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.
