A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. Teats become elongate and swollen during late pregnancy and remain so until weaning is complete. They may be able to colonize or re-colonize former croplands if the soil composition provides good structural support and depth for burrowing. They spend more than 95% of daylight hours aboveground. Their colonial lifestyle likely increases their per-capita survival rate. animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Grazing by cattle may lead to soil erosion that can alter the gypsum surface and threaten prairie dog colonies. Overall, forbs account for nearly 60% of their annual diet, shrubs account for 14% to 17% annually, and grasses account for approximately 22%.

There are five species of prairie dog: black-tailed, Utah, Mexican, white-tailed and Gunnison. Continued decline in geographic distribution of the Mexican prairie dog (Cynomyc mexicanus). Vegetation is typically sparse, though spectacular blooms may occur following rain. Friendly behaviors include a greet-kiss, play, and allogrooming, while aggressive behaviours include chasing, fighting, facing each other while fluffing out their tails, and chasing conspecifics away from individual feeding grounds. (Feldhamer, et al., 2003; Mellink and Madrigal, 1993; Trevino-Villareal and Grant, 1998; Trevino-Villarreal, et al., 1998; Trevino-Villarreal, et al., 1997), Prairie dogs excavate large burrow systems, and this causes subsurface soil to mix with surface soil. Cynomys mexicanus originated about 230,000 years ago from a peripherally isolated population of the more widespread Cynomys ludovicianus.. Reproduction, growth and development and behavior in the Mexican prairie dog, Cynomus mexicanus. These flea species, both of which have been found on Mexican prairie dogs, can be transmitted by other rodents or predators. They acquire all of their water from these plants. In addition, sloped environments are often very rocky and thus provide poor habitat for fossorial animals. active during the day, 2. lasting for one day. Predators include coyotes, bobcats, eagles, hawks, badgers, snakes, and weasels. Similar to black-tailed prairie dogs, Mexican prairier dogs have two distinct coats, one during the summer and one with thick underfur during the winter. Pronatura Noreste, as of February 2007, has signed conservation easements with ejidos and private owners for the protection of more than 42,000 acres (170 km2) of Mexican prairie dog grasslands. Sylvatic plague is a serious infectious disease caused by the bacterium Yersinia pestis, which is transmitted by the flea species Pulex simulans and Opisocrotis hirsutus. "Cynomus mexicanus" (On-line). Prairie dogs are like a squirrel that lives in burrows Greenland. The use of satellite imagery has proven to be helpful in documenting areas in which prairie dogs reside. Habitat fragmentation and a small geographic range have resulted in Cynomys mexicanus being listed as endangered by the IUCN (International Union for Conservation of Nature and Natural Resources). Geographic range of the endangered Mexican prairie dog (Cynomys mexicanus). (Slobodchikoff, et al., 2009), Mexican prairie dogs perform a "greet-kiss" in which two prairie dogs in the same coterie open their mouths, and press their tongues together. Late Pleistocene (Rancholabrean) Cynomus (Rodentia, Sciuridae: prairie dog) from northwestern Sonora, Mexico. Treatment as an agricultural pest has led to its status as an endangered species. Twitter. These mounds, known as rim craters, serve as observation posts for spotting potential predators. (Hoogland, 1995; Slobodchikoff, et al., 2009), Humans have played a significant role in the decline of Cynomys mexicanus. In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. (Mellado, et al., 2005b; Mellink and Madrigal, 1993), Mexican prairie dogs exhibit exceptionally low levels of parasitism. They also have many black whiskers that can reach 3 cm in length. Alarm calls are used when a potential threat has been detected. Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. They are known to have one or two daily activity peaks, and do not hibernate. Females nurse young for 40 to 50 days and weaning occurs at 45 to 50 days after birth. 2005. Prairie Dogs: Communication and Community in an Animal Society. Neonates weigh between 15 and 20 g, and the mean mass of juveniles upon emergence from their burrow varies inversely with litter size.

Escape burrows increase the area in which they can forage, while experiencing minimal risk of predation. 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. Ecology of Mexican prairie dogs, Cynomys mexcianus in El Manantial, northeastern Mexico. Scientific interest in Mexican prairie dogs has increased due to the realization that their populations are declining. This daylight emergence is consistent with the high number of cones and small number of rods within their retinas. Recreational shooting, modification of land for agricultural purposes, soil erosion by cattle herding, and eradication programs have all contributed to their declining numbers. Acta Zoologica Mexicana, 22/3: 107-130. 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. Breeding season in Mexican prairie dogs is longer than in most other Cynomys species due to the climatic conditions of the Mexican Plateau where they are found.

An animal that eats mainly plants or parts of plants. The habitat is commonly surrounded by arid scrub and contains short grasses typical of calcareous and gypsophyllum soils such as creeping muhly (Muhlenbergia repens) and burrograss (Scleropogon brevifolius). (Ceballos-G. and Wilson, 1985; Feldhamer, et al., 2003; Hoogland, 1995; Mellink and Madrigal, 1993; Pizzimenti and McClenaghan Jr., 1974; Rioja-Paradela, et al., 1998; Slobodchikoff, et al., 2009), Both males and females may begin mating before one-year-old, however males typically wait until two years of age. 1998.
