Habitat and Ecology [top]

Habitat and Ecology:This rodent inhabits dry rocky areas with low scrub vegetation where they shelter in crevices (Eisenberg and Redford 1999). Habitat varies from small scattered boulders on flat granitic surfaces to exposed serras with large granitic surfaces. Its range is not restricted by elevation (Lacher 2016). It feeds on leaves, flowers, buds, bark and occasionally fruit. They are excellent climbers and often are observed foraging high in treetops (Lacher 2016). Breeding can occur year round, with the average gestation period being 75-76 days with an average litter size of 1.4. Young are highly precocious and grow fast. The mating system is resource defence polygyny, where the males defend territory for use by multiple females (Lacher 2016).

Threats [top]

Major Threat(s): This species is heavily hunted for food throughout its range, although protected areas offer refuge from hunting for this species. There are probably no major threats throughout its range.

Conservation Actions [top]

Conservation Actions: This rodent occurs in several protected areas which have suitable habitat.
