Habitat and Ecology
[top]
| Habitat and Ecology: |
This rat is most common in forested lowland, in areas of dense undergrowth and around fallen logs.This species adapts well to secondary vegetation and plantations (Emmons and Feer 1997), and it is tolerant to habitat disturbance.
This species is nocturnal, terrestrial, and solitary. It feeds on seeds, fruit, and insects. It runs about actively on the ground or on fallen logs; if frightened, it may bounce away with a series of high jumps. After the initial activity of the night, it may climb onto a branch at 1 to 2 m and rest motionless, head propped on the incisors against the branch. Breeding occurs year-round; litter size is 2 to 5 young, averaging 3.9 (Fleming 1971).
