Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA PRIMATES CHEIROGALEIDAE

Scientific Name: Microcebus danfossi
Species Authority: Olivieri, Zimmermann, Randrianambinina, Rassoloharijaona, Rakotondravony, Guschanski & Radespiel, 2007
Common Name(s):
English Danfoss' Mouse Lemur
Synonym(s):
Microcebus danfossorum Olivieri, Zimmermann, Randrianambinina, Rassoloharijaona, Rakotondravony, Guschanski & Radespiel, 2007 [illegitimate emendation]]
Taxonomic Notes: The original Latin species name was mistakenly amended from the original description to Microcebus danfossorum (Mittermeier et al. 2008) in the mistaken belief that it was named after a husband and wife team, but it was not. It was named after a factory, hence it was a brand name and should be treated as a singular name not a plural.

Justification:
The extent of occurrence (EOO) of this species covers less than 2,100 km2. This geographic range is severely fragmented and is undergoing continuing decline in area of occupancy, extent of occurrence and in quality of habitat. The number of subpopulations and mature individuals is also known to be in decline. Based on these premises, the species is listed as Endangered.

Geographic Range [top]

Range Description: It is known only from six forest fragments between the rivers Sofia and Maevarano in northwestern Madagascar (Olivieri et al. 2007). Prior to recent taxonomic revisions, the mouse lemurs in this region were assumed to be M. ravelobensis. The estimated extent of occurrence (EOO) is less than 2,100 km2.

Population [top]

Population: Population densities vary between 2.2 and 5.0 individuals/ha (which is low compared to other mouse lemur species), and the highest densities are found in disturbed forest fragments which may be due to crowding or edge effects. Almost all sampled populations of M. danfossi show genetic evidence for a relatively rapid crash in population size of about two orders of magnitude. This crash is likely to have occurred within the last 500 years, thus coinciding with accelerated deforestation due to human population expansion in Madagascar (Olivieri et al. 2008).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: An inhabitant of intact and degraded forest fragments from sea level to 780 m. The species has been found in fragments of between 50 and 400 ha in size.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is hunted.

Threats [top]

Major Threat(s):

This species is threatened by habitat loss and degradation from unsustainable farming practices, logging and hunting.

Conservation Actions [top]

Conservation Actions: It is listed on CITES Appendix I. It is known to occur in the Bora Special Reserve, as well as in the Anjiamangirana and Andalirano Classified Forests. However, it is believed that it will have little chance for long-term survival without additional conservation measures; such efforts should include the strengthening of infrastructure within Anjiamangirana I Forest, and the establishment of other protected zones in the forest fragments at Marosakoa, Anjajavy, Ambarijeby and Bekofafa. Further surveys are needed to determine the full extent of its range and population status, and to confirm the taxonomic distinctiveness of this taxon. According to I. J. Porton, this species is not being kept in captivity (Mittermeier et al. 2010 and references therein).
