Akodon serrensis 


Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Rodentia Cricetidae

Scientific Name: Akodon serrensis
Species Authority: Thomas, 1902
Common Name(s):
English Serrado Do Mar Grass Mouse, Serrado Mar Akodont, Serrado Mar Grass Mouse
Taxonomic Notes: This species previously was considered to occur in Argentina; however, the specimens found there are now considered to represent Akodon paranaensis (Christoff et al. 2000). Subgenus Akodon, A. mollis species group (Hershkovitz, 1990). Has been recognized as a species since its description (Cabrera 1961, Gyldenstolpe 1932, Moojen 1952). This species has been most strongly differentiated from other Akodon species based on cytochrome b sequences by Geise et al. (2001). D’Elía et al. (2003) found a single example of A. serrensis to be genetically most similar to Thaptomys nigrita. The taxonomy of this species remains uncertain, further research is required.

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., Patterson, B. & Teta, P.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
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. However some populations of this species are affected by habitat destruction in the Atlantic Forest region.
Previously published Red List assessments:
1996 Lower Risk/least concern (LR/lc)

Habitat and Ecology [top]

Habitat and Ecology: This species occurs in mixed rainforest (Geise et al. 2001). In the Serra do Mar and Serra da Mantiquiera provinces of Brazil, this species is only found above 2000 m (Bonvicino et al. 1997; Geise pers. comm.). The species was found at all elevations sampled between 1,000 m and 2,700 m in a study in Caparao National Park, Brazil. It was most common at intermediate elevations. In the southern part of its range at it occurs at a lower elevation range (Christoff pers. comm.).
Systems: Terrestrial

Threats [top]

Major Threat(s): The Atlantic Forest habitat is affected by habitat destruction (Geise pers. comm.).

Conservation Actions [top]

Conservation Actions: The species occurs in several protected areas throughout its range (Geise and Christoff pers. comm.).
