Microcavia
''Microcavia'' (mountain cavies) is a genus of rodents in the family Caviidae. They are unique within their family in that their premolar teeth do not grow and replace the original deciduous cheek teeth until after the animal is born; in other genera this occurs in the womb. It contains six extant species: * Southern mountain cavy, ''M. australis'' * Jayat's mountain cavy, ''M. jayat'' * Thomas's mountain cavy, ''M. maenas'' * Andean mountain cavy, ''M. niata'' * Shipton's mountain cavy, ''M. shiptoni'' * Sorojchi mountain cavy, ''M. sorojchi'' At least nine fossil species have also been named, dating back to the mid Pliocene The Pliocene ( ; also Pleiocene) is the epoch in the geologic time scale that extends from 5.333 million to 2.58 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Mountain Cavy
The southern mountain cavy (''Microcavia australis'') is a species of South American rodent in the family Caviidae. Description Southern mountain cavies are tailless rodents with short, speckled, greyish-yellow fur, fading to pale grey on the underparts. Adults measure around in total length and weigh between . They have large eyes surrounded by a prominent white ring, and small rounded ears. Females have four teats. Distribution and habitat Southern mountain cavies are largely restricted to Argentina, but may also be found in some neighbouring regions of Chile and Bolivia. They are found across almost the whole of western and southern Argentina, where they inhabit arid and semiarid lowlands, often close to rivers or in areas dominated by thorn bushes. Three subspecies are currently recognised: * ''M. australis australis'' - central western to southern Argentina, from San Juan to Santa Cruz, and parts of south-eastern Chile * ''M. australis maenas'' - northwest Argentina, fro ...

Andean Mountain Cavy
The Andean mountain cavy (''Microcavia niata'') is a species of rodent in the family Caviidae. It is found in Bolivia, Chile and Peru. Feeding The Andean mountain cavy's diet consists of herbs typically of the genus Eleocharis, Distichlis, Verbena, and Deyeuxia ''Deyeuxia'' is a genus of plants allied to the Poaceae Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the gras ..., which are common in bog areas, which suggest that this species of Microcavia only live in bog areas. Characteristics The Andean mountain cavy is usually seen with fur described as pale and soft, with yellow undertones. The dorsal hairs are multicoloured with a grey base, a dark grey middle and yellow tip. The back hairs are measured around 16-18mm and the animals cheeks, throat and belly are white with a grey base.Zeballos, H., Par, A., Pino, K., Medina, C. E., Cordov ...

Cavies
Caviidae, the cavy family, is composed of rodents native to South America and includes the domestic guinea pig, wild cavies, and the largest living rodent, the capybara. They are found across South America in open areas from moist savanna to thorn forests or scrub desert. This family of rodents has fewer members than most other rodent families, with 19 species in 6 genera in 3 subfamilies. Characteristics With the exception of the maras, which have a more rabbit-like appearance, caviids have short, heavy bodies and large heads. Most have no visible tails. They range in size from the smaller cavies at 22 cm in body length, and 300 grams in weight, up to the capybara, the largest of all rodents at 106 to 134 cm in length, and body weights of 35 to 66 kilograms. Even larger forms existed in the Pliocene, such as '' Phugatherium'', which was about the size of a tapir. They are herbivores, eating tough grasses or softer leaves, depending on species.

Taxa Named By Paul Gervais
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodent Genera
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose ...

Thomas's Mountain Cavy
Thomas' is a brand of English muffins and bagels in North America, established in 1880. It is owned by Bimbo Bakeries USA, one of the largest baking companies in the United States, which also owns Entenmann's, Boboli, Sara Lee, Stroehmann, and Arnold bread companies. Advertisements for the muffins place emphasis on their "nooks and crannies". The company also produces toasting or swirl breads, pitas, wraps, and bagels. History The company was founded by Samuel Bath Thomas (1855–1919). In 1874, he immigrated from England to New York City and after other menial jobs began working in a bakery. By 1880, he had purchased his own bakery at 163 Ninth Avenue in Manhattan, where he featured his namesake muffins that were baked on a griddle, not an oven. The business expanded to 337 West 20th Street (a plaque designates the building as "The Muffin House"). Thomas died in 1919, and the company, S. B. Thomas, was inherited by his daughter and nephews, and was incorporated. Later, it wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul Gervais
Paul Gervais full name François Louis Paul Gervais (26 September 1816 – 10 February 1879) was a French palaeontologist and entomologist. Biography Gervais was born in Paris, where he obtained the diplomas of doctor of science and of medicine, and in 1835 he began palaeontological research as assistant in the laboratory of comparative anatomy at the ''Muséum national d'Histoire naturelle''. In 1841 he obtained the chair of zoology and comparative anatomy at the Faculty of Sciences in Montpellier, of which he was in 1856 appointed dean. In 1848–1852 appeared his important work ''Zoologie et paléontologie françaises'', supplementary to the palaeontological publications of Georges Cuvier and Henri Marie Ducrotay de Blainville; of this a second and greatly improved edition was issued in 1859. In 1865 he accepted the professorship of zoology at the Sorbonne, vacant through the death of Louis Pierre Gratiolet; this post he left in 1868 for the chair of comparative anatomy at ...
