Date Assessed: 2017-01-05
Assessor(s): Patton, J. & Percequillo, A.
Reviewer(s): Amori, G.
Justification:
This species is listed as Least Concern in because of its wide distribution, presumed stable population, occurrence in at least two protected areas, probable tolerance to some degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Population [top]

Population:This rodent is known from a few specimens (total = 32) from 7 localities (Patton et al. 2000). It is thought to be reasonably abundant (Patton pers. comm.).
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The majority of specimens were obtained in terra firme forest during survey of the Rio Jurua, some were also collected from seasonally flooded varzea forest (Patton et al. 2000). Pregnant females have been observed during August, September, October, November, May, and June, in both the wet and dry seasons suggesting that reproduction occurs throughout the year (Patton et al. 2000). It is thought that sexual maturity is reached at an early age (Patton et al. 2000).
Systems:Terrestrial
Generation Length (years):1-2
