The gray-headed lemur (Eulemur cinereiceps), or gray-headed brown lemur, is a medium-sized primate, a cathemeral species of lemur in the family Lemuridae. Until a taxonomic revision in 2008, it was known as the white-collared brown lemur or white-collared lemur (Eulemur albocollaris). [4] It lives in south-eastern Madagascar. [1] In 2005, satellite imagery estimates showed approximately 700 km2 (270 sq mi) of total remaining habitat within its geographic range. [5] It is highly threatened by hunting and habitat loss, and was considered to be among the 25 most endangered primates in 2006–2008. [6] It is currently listed as Critically Endangered by the International Union for Conservation of Nature (IUCN) due to a highly restricted range, [1] and has been named one of "The World's 25 Most Endangered Primates." [7]
The gray-headed lemur is only found in southeastern Madagascar, from the Manampatrana River south to the Mananara River. [5] [8]
Recent genetic and morphological evidence has suggested that the former name, E. albocollaris, was actually a junior synonym of E. cinereiceps. [1] Consequently, the common name gray-headed lemur and the scientific name Eulemur cinereiceps were resurrected to replace white-collared brown lemur and E. albocollaris respectively. [4] [9]
Previously, this species was listed as a subspecies of the common brown lemur until elevated to species status in 2001. However, genetic and field studies still support subspecies status under the biological species concept. [5]
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.
Lemuridae is a family of strepsirrhine primates native to Madagascar and the Comoros. They are represented by the Lemuriformes in Madagascar with one of the highest concentration of the lemurs. One of five families commonly known as lemurs. These animals were once thought to be the evolutionary predecessors of monkeys and apes, but this is no longer considered correct. They are formally referred to as lemurids.
True lemurs, also known as brown lemurs, are the lemurs in genus Eulemur. They are medium-sized primates that live exclusively on Madagascar.
The black lemur is a species of lemur from the family Lemuridae. Like all lemurs, it is endemic to Madagascar. Originally, the species was thought to have two subspecies, Eulemur macaco macaco and Eulemur macaco flavifrons, both of which were elevated to species status by Mittermeier et al. in 2008 to Eulemur macaco and Eulemur flavifrons respectively. The most startling difference between the two species is the eye colour; Eulemur flavifrons, the blue-eyed black lemur, has blue eyes, while Eulemur macaco, the black lemur, has brown or orange eyes, and also has ear tufts.
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.
Jolly's mouse lemur is a species of mouse lemur from Mananjary and Kianjavato in Madagascar. The species is named in honor of primatologist Alison Jolly.
Mittermeier's mouse lemur is a species of mouse lemur known only from Anjanaharibe-Sud Special Reserve in Madagascar. The species is named in honor of primatologist Russell Mittermeier, who is President of Conservation International.
Simmons' mouse lemur is a species of mouse lemur known only from Betampona Special Reserve, Analalava Special Community Reserve near Foulpointe, and Zahamena National Park in Madagascar.
The northern rufous mouse lemur, northern brown mouse lemur, or Tavaratra mouse lemur is found in northern Madagascar from the Ankarana Special Reserve in the west to the Manambato River in the 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 Français. Its known distribution cover four protected areas – the Ankarana Special Reserve, and the Analamerana Special Reserve both managed by Madagascar National Parks, the Loky-Manambato protected area (Daraina), and the Andavakoeira-Andrafiamena protected area, both Managed by the NGO Fanamby
The mouse lemurs are nocturnal lemurs of the genus Microcebus. Like all lemurs, mouse lemurs are native to Madagascar.
The collared brown lemur, also known as the red-collared brown lemur or red-collared lemur, is a medium-sized strepsirrhine primate and one of twelve species of brown lemur in the family Lemuridae. It is only found in south-eastern Madagascar. Like most species of lemur, it is arboreal, moving quadrupedally and occasionally leaping from tree to tree. Like other brown lemurs, this species is cathemeral, lives in social groups, primarily eats fruit, exhibits sexual dichromatism, and does not demonstrate female dominance. The species is listed as Endangered by the International Union for Conservation of Nature (IUCN) and is threatened primarily by habitat loss.
Ramanantsoavana's woolly lemur, also known as Ramanantsoavana's avahi or the Manombo woolly lemur, is a species of woolly lemur native to southeastern Madagascar. It weighs about 1 kg. It was originally considered a subspecies of the southern woolly lemur, A. m. ramanantsoavana, but was elevated to a separate species in 2006 based on molecular, phenotypic and morphological data.
MacArthur's mouse lemur, or the Anjiahely mouse lemur, is a species of mouse lemur known only from Makira Natural Park in northeastern Madagascar.
The red-fronted lemur, also known as the red-fronted brown lemur or southern red-fronted brown lemur, is a species of lemur from Madagascar. Until 2001, it was considered a subspecies of the common brown lemur, E. fulvus. In 2001, E. fulvus was split into several separate species, including Eulemur rufus, in which this species was included. In 2008, E. rufus was split into two species, the red lemur and the red-fronted lemur. E. rufus covers the population on the west coast north of the Tsiribihina River and E. rufifrons covers the population on the west coast south of the Tsiribihina River and the population in eastern Madagascar. The species split was based on genetic and morphological evidence. Mitochondrial DNA analysis indicates that E. rufifrons may be more closely related to the common brown lemur, white-headed lemur and Sanford's brown lemur than it is to E. rufus.
The red lemur, also known as the rufous brown lemur or northern red-fronted lemur, is a species of lemur from Madagascar. Until 2001, the species E. rufus was considered a subspecies of the common brown lemur, E. fulvus, after which it was classified as its own species. In December 2008, the species was split into two separate species, the red lemur, E. rufus, distributed in dry lowland forests in northwestern Madagascar, and the red-fronted lemur, E. rufifrons, distributed in southwest and eastern Madagascar. The species split was based on genetic and morphological evidence. Mitochondrial DNA analysis indicates that E. rufifrons may be more closely related to the common brown lemur, white-headed lemur and Sanford's brown lemur than it is to E. rufus.
Mittermeier's sportive lemur is a sportive lemur endemic to the Ampasindava Peninsula in Madagascar.
Lemurs of Madagascar is a 2010 reference work and field guide for the lemurs of Madagascar, giving descriptions and biogeographic data for the known species. The primary contributor is Russell Mittermeier, president of Conservation International, and the cover art and illustrations were drawn by Stephen D. Nash. Currently in its third edition, the book provides details about all known lemur species, general information about lemurs and their history, and also helps travelers identify species they may encounter. Four related pocket field guides have also been released, containing color illustrations of each species, miniature range maps, and species checklists.
The World's 25 Most Endangered Primates is a list of highly endangered primate species selected and published by the International Union for Conservation of Nature (IUCN) Species Survival Commission (SSC) Primate Specialist Group (PSG), the International Primatological Society (IPS), Global Wildlife Conservation (GWC), and Bristol Zoological Society (BZS). The IUCN/SSC PSG worked with Conservation International (CI) to start the list in 2000, but in 2002, during the 19th Congress of the International Primatological Society, primatologists reviewed and debated the list, resulting in the 2002–2004 revision and the endorsement of the IPS. The publication was a joint project between the three conservation organizations until the 2012–2014 list when BZS was added as a publisher. The 2018–2020 list was the first time Conservation International was not among the publishers, replaced instead by GWC. The list has been revised every two years following the biannual Congress of the IPS. Starting with the 2004–2006 report, the title changed to "Primates in Peril: The World's 25 Most Endangered Primates". That same year, the list began to provide information about each species, including their conservation status and the threats they face in the wild. The species text is written in collaboration with experts from the field, with 60 people contributing to the 2006–2008 report and 85 people contributing to the 2008–2010 report. The 2004–2006 and 2006–2008 reports were published in the IUCN/SSC PSG journal Primate Conservation,, since then they have been published as independent publications.
Lemurs were first classified in 1758 by Carl Linnaeus, and the taxonomy remains controversial today, with approximately 70 to 100 species and subspecies recognized, depending on how the term "species" is defined. Having undergone their own independent evolution on Madagascar, lemurs have diversified to fill many ecological niches normally filled by other types of mammals. They include the smallest primates in the world, and once included some of the largest. Since the arrival of humans approximately 2,000 years ago, lemurs have become restricted to 10% of the island, or approximately 60,000 square kilometers (23,000 sq mi), and many face extinction. Concerns over lemur conservation have affected lemur taxonomy, since distinct species receive increased conservation attention compared to subspecies.
