The Maule tuco-tuco (Ctenomys maulinus) is a species of rodent in the family Ctenomyidae. [2] 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.

Description

The Maule tuco-tuco is a medium-sized tuco-tuco, there being two subspecies, C. m. maulinus and C. m. brunneus, the former growing to a total length of 275 mm (10.8 in) and the latter 305 mm (12.0 in). C. m. maulinus is a uniform pale brown colour with a similarly coloured tail terminating in a white "pencil" or tuft of hair. By contrast, C. m. brunneus has a more intense brown colour, with the feet, the underside of the tail and the tail-tip pencil being buff-white. [3]

Distribution and habitat

The nominate subspecies C. m. maulinus is found in Talca Province, Chile while C. m. brunneus occurs in Mallecco Province and Cautín Province, Chile, at altitudes between about 1,000 and 2,000 m (3,300 and 6,600 ft). More recently, this tuco-tuco has been discovered in Neuquén Province and Río Negro Province in Argentina, but it is unclear which of the two subspecies was involved in these sightings. [3] This tuco-tuco inhabits different habitat types, including Nothofagus and Araucaria woodland and open areas where the soil consists of volcanic sands. [4] The range of this species may overlap that of the social tuco-tuco (Ctenomys sociabilis). [5]

Ecology

Like other tuco-tucos, this species is a burrowing rodent that feeds on vegetable matter such as roots and grasses. Two burrows have been excavated and found to extend for 14 and 49 m (46 and 161 ft). Some food is taken back to the burrow and stored there in special chambers. [4] In a cave in Neuquén Province, Argentina, owl pellets dating back more than 5,000 years have been discovered which contain skin fragments and bones of a large species of tuco-tuco, which is probably the Maule tuco-tuco. [3]

Status

C. maulinus has a wide range in Chile and northern Argentina, where it is found at altitudes between about 900 and 2,000 m (3,000 and 6,600 ft). This tuco-tuco is present in several protected areas and is assumed to have a large total population. No particular threats have been identified and any downward trend in populations is likely to be slow, so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".

A tuco-tuco is a neotropical rodent in the family Ctenomyidae. Tuco-tucos belong to the only living genus of the family Ctenomyidae, Ctenomys, but they include approximately 60 different species. The common name, "tuco-tuco" comes from the "tuc-tuc" sound they make while they dig their burrows.

Haig's tuco-tuco, known regionally as the Patagonian tuco-tuco, is a hystricognath rodent. Like other tuco-tucos it is subterranean and thus not often observed, although the "tuc-tuc" call of the males can be heard near burrow sites, especially in the early morning. Like most species in the genus Ctenomys, C. haigi are solitary, with one adult per burrow.

<span class="mw-page-title-main">Pearson's tuco-tuco</span> Species of rodent

Pearson's tuco-tuco is a species of rodent in the family Ctenomyidae. It is endemic to Uruguay, where it is found at elevations below 200 m. This tuco-tuco constructs burrows with multiple openings containing one to two nests of dried grass; it prefers areas of sandy soil but is somewhat adaptable. It is threatened by loss of habitat to development, agriculture and ranching. Multiple karyotypes have been reported, including 2n = 68–70, FN = 80–88, as well as 2n = 56, FN = 77–79, suggesting the taxon may represent several species. C. dorbignyi appears to be cytogenetically indistinguishable from the 2n = 70 form. The species is named after American zoologist Oliver Payne Pearson.
