“…Housse (1953) also notes that it dens in bamboo thickets. Pearson (1983) examined the small mammal fauna of the southern Andean moist temperate forest, focusing on Argentina's Nahuel Huapi National Park, where the kodkod is known to occur. He found that this forest type, with which the kodkod is strongly associated (see below), has a high diversity of mouse-sized rodents, but lacks diversity of larger mammals, noticeably of the arboreal type (no squirrels or monkeys).…”

“…The Andean mountain cat is a small but sturdy cat: one male from Peru weighed 4 kg (Pearson 1957). It has long ash-grey fur indistinctly patterned with rusty rosette-like spots on the sides, and marked with conspicuous thick dark stripes extending down the sides from the back.…”

“…Its nose is black, and its belly pale, with dark spots. The tail is thick and long (about 70% of head-body length: Osgood 1943, Pearson 1957, Cabrera 1961, Pine et al 1979, banded with approximately seven conspicuous dark rings. The mountain cat is characterized by large auditory bullae of a form unique among the felids, the anterior chamber being somewhat larger than the posterior (Kuhn 1973).…”

“…Lack of knowledge is obviously a factor. The few observations of the species were all in the daytime, and details regarding collection or observation, typically made during general mammal surveys, are sparse (e.g., Pearson 1957, Greer 1965b, Grimwood 1969, Pine et al 1979, Melquist 1984. With regard to human action, it appears that two of the usual human-induced causes of rarityhabitat loss/modification and direct persecution-are only partially responsible.…”

“…The Chilean tree mouse Irenomys tarsalis (Philippi, 1900) is a large rodent that inhabits the temperate rainforests of southern Chile and adjacent Argentina (Pearson 1983;1995;Kelt 1993). Considered one of the rarest sigmodontines of the Southern Temperate Rainforests, the phylogenetic relationship of the species is still debated and very little is known of its natural history (Pardiñas et al 2004;D'Elía et al 2006;Kelt et al 2008).…”

Mammalia, Rodentia, Cricetidae, Irenomys tarsalis (Philippi, 1900): new records for Argentina and filling gaps

Ten new records for the Chilean tree mouse, Irenomys tarsalis, are presented from western Argentina. This represents a near 30 % increase in the number of known localities for the species in this country. Nine of them fill a gap of at least 125 km in western Chubut Province, where I. tarsalis was previously known for only three records. Additionally, environmental information at an ecoregional and habitat scale is provided.

Approximately 700 Abrothrix longipilis were trapped in Argentina, and their reproductive organs were studied. Some were kept briefly in captivity. Males have the same body length as females but are 8% heavier. Sexually immature males are shorter and lighter than breeding males of the same age. Few individuals in the wild live as long as two years. All overwintering males come into breeding condition in the spring and become infertile in the autumn. All overwintering females have open vaginas in the spring, and most undergo several infertile ovulatory cycles, probably without copulating, before they become pregnant. Corpora lutea of the sterile cycles accumulate; there may be as many as 28 in a pair of ovaries. The average number of ova shed per cycle is 4.66; average litter size is 3.85. Ovulation is spontaneous. There is postpartum ovulation and fertilization without intervening sterile cycles but with maintenance of old corpora lutea. Unusual architecture of the penis and vagina may result from unusual timing of hormone production during development, and the disjunction of ovulation and fertilization may similarly result from hormonal heterochrony at the beginning of the breeding season. The apparently nonadaptive wastage of ova in sterile cycles may be a novel example of kin selection.
