The Cheirogaleidae are the family of strepsirrhine primates containing the various dwarf and mouse lemurs. Like all other lemurs, cheirogaleids live exclusively on the island of Madagascar.
The woolly lemurs, also known as avahis or woolly indris, are nine species of strepsirrhine primates in the genus Avahi. Like all other lemurs, they live only on the island of Madagascar.
The fat-tailed dwarf lemur, also known as the lesser dwarf lemur, western fat-tailed dwarf lemur, or spiny forest dwarf lemur, is endemic to Madagascar.
Ankarana Special Reserve in northern Madagascar was created in 1956. It is a small, partially vegetated plateau composed of 150-million-year-old middle Jurassic limestone. With an average annual rainfall of about 2,000 millimetres (79 in), the underlying rocks have been eroded to produce caves and feed subterranean rivers—a karst topography. The rugged relief and the dense vegetation have helped protect the region from human intrusion.
The eastern lesser bamboo lemur, also known as the gray bamboo lemur, the gray gentle lemur, and the Mahajanga lemur is a small lemur endemic to Madagascar, with three known subspecies. As its name suggests, the eastern lesser bamboo lemur feeds mainly on bamboo. The lemurs of the genus Hapalemur have more manual dexterity and hand–eye coordination than most lemurs. They are vertical climbers and jump from stalk to stalk in thick bamboo forests.
The greater dwarf lemur, or the Geoffroy's dwarf lemur, is a lemur that is widely distributed over the primary and secondary forests near the eastern coast of Madagascar. They are also found in northern parts of Madagascar. Greater dwarf lemurs live in forests and dry scrub areas. The head and body of the greater dwarf lemur can range from 167 to 264 millimeters in length, and 164 to 600 grams. Their tails can range from 195 to 310 millimeters in length.
The furry-eared dwarf lemur, or Crossley's dwarf lemur, only found on the island of Madagascar, as with all other lemurs. It has a pelage coloration that is red-brown dorsally and gray ventrally. The eye-rings of this species are blackish and the ears are black inside and out. Cheirogaleus crossleyi species are obligated to hibernate during periods of food scarcity on the island of Madagascar. Cheirogaleus crossleyi species specifically undergo drastic fluctuations in temperature during hibernation.
The northern rufous mouse lemur, northern brown mouse lemur, or Tavaratra mouse lemur is found in Northern Madagascar from the Ankarana National Park in the West to the river Manambato in Northeast and up to the Irodo river in the North of the Analamerana Special Reserve. The complete distribution range of M. tavaratra is still to be defined as some areas surrounding the described distribution have not been visited yet. For example, M.tavaratra has been reported to possibly occur from the Irodo up to the Montagne des Francais by Louis and collaborators in. Its known distribution cover four protected areas the Ankarana National Park, and the Analamerana Special Reserve both managed by Madagascar National Parks, the Loky-Manambato Region (Daraina) and the Andavakoeira-Andrafiamena protected area, both Managed by the NGO Fanamby
The Amber Mountain fork-marked lemur, also known as the Montagne d'Ambre fork-crowned lemur or Tanta, is a small primate, and like the other lemurs, can only be found on the island of Madagascar. The species is named after the Amber Mountain National Park where they are found.
The dwarf lemurs are the lemurs of the genus Cheirogaleus. All of the species in this genus, like all other lemurs, are native to Madagascar.
The Ankarana sportive lemur, or Ankarana weasel lemur, is a sportive lemur endemic to Madagascar. It is one of the smaller sportive lemurs with a total length of about 53 cm (21 in), including 25 cm (9.8 in) of tail. Average body weight is approximately 750 grams (1.65 lb). The Ankarana sportive lemur is found in northern Madagascar, living in dry lowland forests in Ankarana, Andrafiamena and Analamerana, and in moist montane forest of Montagne d'Ambre.
Sibree's dwarf lemur is a small nocturnal lemur endemic to Madagascar.
Perrier's sifaka is a lemur endemic to Madagascar. It was formerly considered to be a subspecies of diademed sifaka It has a very small range in northeastern Madagascar where its habitat is dry deciduous or semihumid forest. Part of its range is in protected areas. It is an almost entirely black sifaka and measures about 90 cm (35 in), half of which is a bushy tail. Females are slightly larger than males.
The southern woolly lemur, or southern avahi, has been recently recognized as a separate species of woolly lemur in 2006 by Zaramody et al. It is a nocturnal and pair-living species. Groups can range from 2 to 5 individuals. A study in Sainte Luce forest revealed home range varied from 2.2 to 3.5 ha and that males can have larger home range and cover longer daily distances than females, in agreement with the territory defence and mate guarding hypotheses.
The Lavasoa dwarf lemur is a small, nocturnal strepsirrhine primate and a species of lemur that is endemic to three small, isolated patches of forest on the southern slopes of the Lavasoa Mountains in southern Madagascar. Fewer than 50 individuals are thought to exist. Its habitat lies in a transitional zone between three ecoregions: dry spiny bush, humid littoral forest, and humid forest. First collected in 2001 and thought to be a subpopulation of the furry-eared dwarf lemur (C. crossleyi), it was not formally described until 2013. It is one of six species of dwarf lemur, though the research that identified it also suggested the existence of many more new species.
The Montagne d'Ambre dwarf lemur or Andy Sabin's dwarf lemur is a species of dwarf lemur known only from Amber Mountain National Park and the surrounding area in northern Madagascar. It was identified in 2005, but not formally described until 2015. It is an endangered species, at risk from deforestation and possibly hunting from nearby human populations.
Primate Conservation is a journal published by the IUCN Species Survival Commission's Primate Specialist Group about the world's primates. First published as a mimeographed newsletter in 1981, the journal today publishes conservation research and papers on primate species, particularly status surveys and studies on distribution and ecology. Besides these regular papers, the journal has also been a significant place for primatologists to publish descriptions of new primate species in Primate Conservation.
Groves' dwarf lemur is a species of dwarf lemur known from Ranomafana and Andringitra national parks and surrounding areas in southeastern Madagascar. The identification was based on comparison of mitochondrial and nuclear gene sequences with other members of the C. crossleyi group. Individuals from this clade first came under genetic study in 1999 and were recognized as a new species in 2014, but it was not formally described until 2017. The lemur was named after mammalologist Colin Groves. Known from altitudes from 754 to 999 m, it is significantly larger than other members of the C. crossleyi group, with a 20 cm body length, a 29 cm tail, and a weight of 0.41 kg. While the conservation status of the new species has not yet been assessed, its presence in several national parks does not guarantee that it will not be threatened by deforestation ongoing on the island, or possibly by hunting.
