Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA PRIMATES CHEIROGALEIDAE

Scientific Name: Mirza coquereli
Species Authority: (A. Grandidier, 1867)
Common Name(s):
English Coquerel's Giant Mouse Lemur, Coquerel's Dwarf Lemur, Coquerel's Mouse-lemur
Taxonomic Notes: Recent analyses of morphometric, genetic, and behavioural data has now resulted in the recognition of a second species of Mirza. Mirza coquereli is the larger of the two, with a distribution nucleus in southwestern Madagascar, while the newly described, smaller-bodied Mirza zaza is found in the Sambirano region of the far northwest (Kappeler et al. 2005).

Reviewer(s): Schwitzer, C. & Molur, S.
Facilitator/Compiler(s): Chiozza, F. & Clark, F.
Justification:

Listed as Endangered as the species is suspected to have undergone a population decline of ≥50% over a period of 10 years, due primarily to continuing decline in area, extent and quality of habitat. These causes have not ceased, and will to a large extent not be easily reversible. A population reduction of ≥50% is also suspected to be met in the future (over a period of 10 years) due to the same causes.

1990 Vulnerable (IUCN 1990)
1990 Vulnerable (IUCN 1990)

Geographic Range [top]

Range Description: Coquerel’s Giant Mouse Lemur is found in lowland dry forests of western Madagascar, from sea level to 700 m. One nucleus is in the south-west between the Onilahy River to the south and the Tsiribinha River to the north, including Vohibasia and Zombitse National Parks and Isalo National Park. To the north of the Tsiribihina River, it has also been reported from the the Andranomena Special Reserve and Tsingy de Bemaraha National Park, and recent sightings confirm its presence in Tsingy de Namoroka National Park and in the region of Sahamalaza (see Mittermeier et al. 2008 and references therein). Farther north, the newly described M. zaza inhabits the Sambirano region.

Population [top]

Population: Population densities reported from Marosalaza range from 30 to 50 individuals/km2 but, in the latter study, reached as high as 210 individuals/km2 in forests running along rivers (see Mittermeier et al. 2008 and references therein). Densities of 100 individuals/ km2  have also been recorded in Tsimembo forest by Ausilio and Raveloarinoro (1993). In Kirindy, Kappeler (1997) recorded 120 individuals/km2, but the population underwent an inexplicable decline after being steady for several years. Its population distribution is patchy due to high levels of fragmentation in its known region (Ganzhorn 1994).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species inhabits dry deciduous forest, and is found near rivers and ponds in dense forest. M. coquereli is adaptable and can survive in secondary forest, including gallery forests and coffee plantations. The species is typically solitary, choosing to forage alone, but mother and offsprings tend to nest communally (Kappeler 2003); it spends daytime hours in a spherical nest of up to one-half meter in diameter, usually placed 2-10 m high in the fork of a large branch or among dense lianas. Reproductive activity of M. coquereli in the Kirindy Forest begins in November. Gestation lasts about three months and two infants (occasionally one) leave the nest after about three weeks (see Mittermeier et al. 2008 and references therein).
Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is hunted for food.

Threats [top]

Major Threat(s): This species is threatened by habitat loss due to slash-and-burn agriculture and charcoal production. This has been particularly heavy in the southern and western part of its range. It is also taken for food in some parts of its range in western Madagascar.


Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. It is believed to be present in two or three national parks (Tsingy de Bemaraha, Zombitse-Vohibasia, and possibly Kirindy Mitea National Park), in Tsingy de Bemaraha Strict Nature Reserve, and in Andranomena Special Reserve. It is also present in the Kirindy Forest (part of the Menabe-Antimena Protected Area) and in Ampataka Classified Forest. It appears to be adaptable, can survive in secondary forest, and occurs in fairly high densities in some parts of its range. About half a dozen individuals may be in non-breeding captivity, in the US and Europe (ISIS 2009). However, according to A. Katz (pers. comm.), misidentification could have taken place as they may in fact be Mirza zara individuals.
