The Chalchalero viscacha rat or Chalchalero vizcacha rat (Tympanoctomys loschalchalerosorum) is a species of caviomorph rodent in the family Octodontidae. [2] It was formerly considered to be monotypic within the genus Salinoctomys, [2] but has been shown by genetic analysis to nest within Tympanoctomys , and in particular, within the variation of T. barrerae . [1] [3] The species is endemic to a small area of northwestern Argentina, where it lives in shrublands bordering the salt flats of the Salinas Grandes. [1] Its diet consists of halophyte plants. [1] It is named after an Argentine musical group, Los Chalchaleros, whose songs were popular with its discoverers. [4]
The Chalchalero viscacha rat is a medium-sized species of rat. Its dorsal fur is dark brownish black while its underparts are white. The hairs on its back are about 2 centimetres (0.8 in) long and have a grey base, a brown band and a black tip, and the guard hairs are a uniform darkish brown. This viscacha rat reaches a head-and-body length of 14 to 16 centimetres (5.5 to 6.3 in) with a tail length of 11 to 12 centimetres (4.3 to 4.7 in). The tail is relatively long, clad with hair along its entire length and ends with a black tassel. The soles of the feet have six pads, and there is a fringe of hairs around the feet. [5]
It is only found within an area totalling less than 100 square kilometres (39 sq mi) and it actually occupies only about one tenth of that area. It lives among the salt-loving plants that grow between the salt pans and the dense thorn scrub typical of the surrounding area. Its population is decreasing and the International Union for Conservation of Nature has rated its conservation status as "critically endangered". [1]
Kirchner, a surname of German origin, from the Middle High German word, 'kirchenaere'. Kirchner originated as an occupational surname for a church worker, such as a priest, church assistant or a church property administrator. Notable people with the name include:
The golden viscacha rat or golden vizcacha rat is the single species of the genus Pipanacoctomys of the rodent family Octodontidae. It has 92 chromosomes and has been regarded as tetraploid. This octodontid and its sister-species, the plains viscacha rat, may have arisen from the diploid mountain viscacha rat, as a result of the doubling and subsequent loss of some chromosomes. However, some genetic studies have rejected any polyploidism in mammals as unlikely, and suggest that amplification and dispersion of repetitive sequences best explain the large genome size.
Los Chalchaleros were an Argentine musical folkloric ensemble consisting of four men, and one of the most famous folk singers in the history of Latin America. The group was established in 1948 in the northern province of Salta. It was named after a local song-bird, the chalchalero. They left the stages and recording in 2003.
The Atlantic bamboo rat, or southern bamboo rat, is a spiny rat species found in humid tropical forests in Argentina, Brazil and Paraguay. It is the only member of the genus Kannabateomys.
Bennett's chinchilla rat is a species of chinchilla rat in the family Abrocomidae. It is found only in Chile where its habitat is Mediterranean-type scrub on the western side of the Andes. The IUCN has assessed its conservation status as being of "least concern".
The Chilean rock rat is a species of rodent in the family Octodontidae. It is found in the high Andes of Argentina and Chile.
The southern tuco-tuco is a species of rodent in the family Ctenomyidae. It is endemic to Argentina.
The Maule tuco-tuco is a species of rodent in the family Ctenomyidae. It is found in Argentina and Chile where it occupies several different types of habitats. It is a common species and the IUCN has assessed its conservation status as being of "least concern". The common and scientific names refer to a river and region in Chile within its range.
The armored rat is a species of rodent in the family Echimyidae. It is monotypic within the genus Hoplomys. It is found in Latin America, from northern Honduras to northwest Ecuador. It possesses a range of spines on its back and sides of the body.
The northern viscacha is a species of viscacha, a rodent in the family Chinchillidae. It is known from Peru and Chile, at elevations from 300 to 5000 m, and may also be present in Bolivia.
The plains viscacha or plains vizcacha is a species of viscacha, a rodent in the family Chinchillidae. It is the only living species within the genus Lagostomus. It is found in Argentina, Bolivia, and Paraguay. The plains viscacha is the largest species in its family. They construct elaborate burrows that house successive colonies for decades.
The prehensile-tailed hutia is a small, furry, rat-like mammal found only in forests on Cuba. It is the only member of the genus Mysateles. It climbs and lives in trees where it eats only leaves, and it is threatened by habitat loss. The prehensile-tailed hutia is a member of the hutia subfamily (Capromyinae), a group of rodents native to the Caribbean that are mostly endangered or extinct. There is one subspecies, M. prehensilis gundlachi.
The mountain viscacha rat or mountain vizcacha rat, historically viscacha rat or vizcacha rat, is a species of rodent in the family Octodontidae. It is endemic to Argentina.
The plains viscacha rat, plains vizcacha rat, red viscacha rat, or red vizcacha rat is a species of rodent in the family Octodontidae native to Argentina. It is one of three species in the genus Tympanoctomys.
Tympanoctomys is a genus of rodent in the family Octodontidae. There are three extant species in the genus: T. barrerae, T. kirchnerorum and T. loschalchalerosorum. T. loschalchalerosorum was formerly considered to be monotypic within the genus Salinoctomys, but has been shown by genetic analysis to nest within the variation of T. barrerae.
Viscacha rats are a group of rodents in the family Octodontidae. All species are found in Argentina. They are placed in the following genera:
The Uspallata chinchilla rat is a species of chinchilla rat in the family Abrocomidae native to Argentina. This species was identified in 2002, by Braun and Mares from the University of Oklahoma. Only a single specimen has been examined.
Octodontidae is a family of rodents, restricted to southwestern South America. Fourteen species of octodontid are recognised, arranged in seven genera. The best known species is the common degu, Octodon degus.
Kirchner's viscacha rat or Kirchner's vizcacha rat is a species of rodent in the family Octodontidae described in 2014. It is one of two species in the genus Tympanoctomys. That species is endemic to Chubut Province in the central western Argentina, where it has a fragmented range. Its natural habitat is desert scrubland, dunes and salt flats, where it eats halophyte plants. It is a solitary, nocturnal rodent that constructs large mounds with complex burrows. The species was named in honor of both Cristina Fernández de Kirchner and Néstor Kirchner, presidents of Argentina.
