This rat has been recorded in terra firme forest, including naturally disturbed forest with either high density of bamboo or in second growth. It is commonly found in disturbed second growth forests, active and abandoned cultivated plots and various edge habitats. It is less frequently found in forest that floods occasionally, not seasonally. This rodent has not been found in varzea forest (J. Patton pers. comm.). The modal litter size was 2 (range one to four). It is not known whether reproduction is seasonal or largely aseasonal in Brazil (Patton et al., 2000).
