Utah Prairie Dog
The Utah prairie dog (''Cynomys parvidens'') is the smallest species of prairie dog endemic to the south-central steppes of the American state of Utah. The species is listed in the IUCN Red List of Threatened Species with a status of Endangered. Because of this, it is a protected species; the prairie dog faces various threats - the most dangerous being habitat loss and disease. Description Appearance The fur of Utah prairie dogs is multicolored, which consists of black, brown, and dark brown at the tip. Their faces have dark brown cheeks and whitish tone around their chins and mouth.Pizzimenti JJ, Collier GD (1975) Cynomys parvidens. Mamm Spec 52:1–3 Utah prairie dogs also have distinctly clay colored proximal tail parts and dorsum, as well as dark eyebrows. In terms of taxonomy, there are two subgenera of prairie dogs: "black-tailed" prairie dogs and "white-tailed" prairie dogs. Utah prairie dogs are a member of the latter of the two groups and the subgenus ''Leucrossuromy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joel Asaph Allen
Joel Asaph Allen (July 19, 1838 – August 29, 1921) was an American zoology, zoologist, mammalogy, mammalogist, and ornithology, ornithologist. He became the first president of the American Ornithologists' Union, the first curator of birds and mammals at the American Museum of Natural History, and the first head of that museum's Department of Ornithology. He is remembered for Allen's rule, which states that the bodies of endotherms (warm-blooded animals) vary in shape with climate, having increased surface area in hot climates to lose heat, and minimized surface area in cold climates, to conserve heat. Early life Allen was born in Springfield, Massachusetts, the son of Joel Allen and Harriet Trumbull. He studied and collected specimen of natural history early in life, but he was forced to sell his relatively large collection so that he could attend the Wilbraham & Monson Academy in 1861. The following year, he transferred to Harvard University, where he studied under Louis Agassi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subgenera
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', a ...

Sevier County, Utah
Sevier County ( ) is a county in Utah, United States. As of the 2010 United States Census, the population was 20,802. Its county seat and largest city is Richfield. History Evidence of indigenous peoples residing in Sevier County up to 5,000 BP has been unearthed. The Fremont culture of Native Americans occupied the area from about 2000 to 700 BP.

In Utah, the Numic- (or Shoshonean) speaking peoples of the Uto-Aztecan language family evolved into four distinct groups in the historical period: the Northern Shoshone, Goshute or Western Shoshone, Southern Paiute, and Ute peoples. This territory's central and eastern sections were occupied primarily by various bands of the Ute.

Black-tailed Prairie Dog
The black-tailed prairie dog (''Cynomys ludovicianus'') is a rodent of the family Sciuridae found in the Great Plains of North America from about the United States-Canada border to the United States-Mexico border. Unlike some other prairie dogs, these animals do not truly hibernate. The black-tailed prairie dog can be seen above ground in midwinter. A black-tailed prairie dog town in Texas was reported to cover and included 400,000,000 individuals. Prior to habitat destruction, the species may have been the most abundant prairie dog in central North America. It was one of two prairie dogs described by the Lewis and Clark Expedition in the journals and diaries of their expedition. Description Black-tailed prairie dogs are generally tan in color, with lighter-colored bellies. They may have color variation in their pelt, such as dark fur on their back in black and brown tones.

Mexican Prairie Dog
The Mexican prairie dog (''Cynomys mexicanus'') is a diurnal burrowing rodent native to Mexico. Treatment as an agricultural pest has led to its status as an endangered species. 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 ludovicianus''. Ecology These prairie dogs prefer to inhabit rock-free soil in plains at an altitude of . They are found in the regions of southern Coahuila and northern San Luis Potosí in northern Mexico, where they eat herbs and grasses native to the plains where they live. They acquire all of their water from these plants. Although mainly herbivores, they have been known to eat insects. Predators include coyotes, bobcats, eagles, hawks, badgers, snakes, and weasels. Northern prairie dogs hibernate and have a shorter mating season, which generally lasts from January to April. After one month's gestation, femal ...
