Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA RODENTIA CRICETIDAE

Scientific Name: Akodon montensis
Species Authority: Thomas, 1913
Common Name/s:
English Montane Akodont
Taxonomic Notes: Subgenus Akodon, A. cursor species group (Rieger et al. 1995). Originally named as a subspecies of A. arviculoides, a ranking observed by Gyldenstolpe (1932) and Cabrera (1961). Where A. cursor and A. montensis occur in proximity, the latter species is found at higher elevations, 800 m and above (Geise et al. 2001). Past reports for this species in Uruguay (e.g., Ximénez and Langguth 1970) have proven to be A. reigi (González et al. 1998).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor/s: Pardinas, U., D'Elia, G., Fagundes, V., Christoff, A. & Geise, L.
Reviewer/s: Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
This species is listed as Least Concern in view of its wide distribution, presumed large population, it occurs in a number of protected areas, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Geographic Range [top]

Range Description: This species occurs from east Paraguay (Gamarra de Fox and Martin, 1996), northeast Argentina (Pardiñas et al., 2003), and southeast Brazil (Rio de Janeiro to Rio Grande do Sul, including gallery forest settings in Minas Gerais and Goiás; Geise et al. 2001; Rieger et al. 1995). In Brazil, the species occurs from coastal areas inland to eastern Mato Grosso do Sul.

Population [top]

Population: It is an abundant species.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: The species inhabits Atlantic forest and cerrado. Akodon montensis has been collected only above 800 m in Rio de Janeiro State, and in northern-most areas of its distribution it occurs above 900 m. Species occurs in gallery forest along creeks and streams (Pardiñas et al. 2005).
Systems: Terrestrial

Threats [top]

Major Threat(s): Although there are no major threats to the species, the Atlantic forest populations are affected by habitat destruction.

Conservation Actions [top]

Conservation Actions: The species occurs in protected areas throughout its range (Fagundes pers. comm.). At present the efficient method of identifying species is using karyotyping (2n = 24, 25, 26) (Fagundes pers. comm.).
