Kingdom | Animalia |
Phylum | Chordata |
Class | Mammalia |
Order | Rodentia |
Family | Cricetidae |
Genus | Punomys (1) |
A stocky, vole-like rodent, the eastern puna mouse (Punomys kofordi) takes its scientific name from the American naturalist and conservationist Dr Karl B. Kofordi (2) (3). Its common name is derived from the puna grassland region it inhabits in the eastern Andes, where it is unusual in being one of the only mammals that is found entirely at such high elevations (2).
The long, soft, loose fur of the eastern puna mouse is generally dull buffy-brown or greyish-brown on the upperparts, and white or greyish on the underparts, with a buffy wash. The tail is usually dusky above and white below, and the hands and feet are dusky on the top and black below, with small claws (2).
A small, agile species, the eastern puna mouse feeds primarily on plants, particularly Senecio adenophylloides and Werneria digitata. It is a remarkably dextrous rodent, able to manipulate and cut twigs as long as 50 centimetres with its stout incisors. The eastern puna mouse usually stores the cut twigs in a cache under a rock, sometimes storing as many as 30 twigs in one cache (2).
The eastern puna mouse is active during the day, when it will scurry from place to place in the shelter of rocks. This species is thought to breed during the dry season, possibly between June and September (2).
Found only in the moist habitats of the puna grassland in Peru, the eastern puna mouse generally inhabits barren, rocky areas, particularly where plants of the genus Senecio are abundant (1) (2). It may also be found in areas of traditional pasture (1).
The eastern puna mouse is classified as Vulnerable (VU) on the IUCN Red List (1).
The eastern puna mouse has a very restricted distribution and has been recorded in only five locations. Although there are currently no major threats to the eastern puna mouse, its limited range means that it is vulnerable to changes in its habitat, such as the drainage of suitable wet areas (1).
Climate change is also a potential threat to this species, due to its restricted elevational range. Climate change may cause some areas of currently suitable habitat to be lost as conditions change, which may threaten the small population of the eastern puna mouse if it is unable to adapt quickly enough (1).
The eastern puna mouse is not known from any protected areas. This species would greatly benefit from further research into its habitat, ecology and threats (1).
