Habitat and Ecology [top]

Habitat and Ecology:This mouse is nocturnal (Emmons and Feer, 1998) and it is known from undisturbed terra firme forest on the ground; these sites were often in areas of local, natural disturbances, such as tree falls. Pregnant females or those with a perforate vagina were obtained from August through March, suggesting that breeding occurs in both wet and dry seasons and perhaps throughout the year. Embryo counts ranged from one to three (Patton el al., 2000). This species is found in lowland and piedmont Amazon rainforest. It is found in disturbed and primary forest. This species is a forest specialist.
Generation Length (years):1-2

Threats [top]

Major Threat(s): Some populations are threatened by general deforestation in the Amazon region (R.P. Anderson pers. comm.), but overall this is not considered a major threat.

Conservation Actions [top]

Conservation Actions: This species occurs in many protected areas throughout its range.
