Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA RODENTIA MURIDAE

Scientific Name: Mastomys pernanus
Species Authority: (Kershaw, 1921)
Common Name(s):
English Dwarf Mastomys, Dwarf Multimammate Mouse

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Granjon, L., van der Straeten, E., Corti, M. & Agwanda, B.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Justification:
Listed as Data Deficient since, the distribution of Mastomys pernanus was thought to be restricted until the recent discovery of a specimen 550 km south of the known range. The habitat between the two areas is thought to be continuous and potentially favorable. The species is not abundant when trapping, but evidence of the species is found in owl pellets. It may be that the species is more common than thought and it is just the trapping techniques used that are unsuitable for catching this species.
History:
2004 Data Deficient
2002 Data Deficient
1996 Vulnerable
1994 Insufficiently Known (Groombridge 1994)

Population [top]

Population: It is known from very few specimens, and from the low trapping success, it appears to be uncommon to rare, however, this may be an artefact of the methodology used.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It is found in moist savanna. This does not appear to be a commensal species.
Systems: Terrestrial

Threats [top]

Major Threat(s): The habitat is being fragmented, but not enough to consider this a major threat. Likewise, fire is part of the natural cycle and not a major threat (one of the areas where this species was recorded was burnt, completely transforming the habitat and the fauna).

Conservation Actions [top]

Conservation Actions: There are protected areas in the region that this species might occur in (e.g., Akagera Park in Rwanda).
