Distribution of E. rufifrons [1] |
The red-fronted lemur (Eulemur rufifrons), 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. [4] 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 (E. rufus) and the red-fronted lemur (E. rufifrons). [3] 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. [3] The species split was based on genetic and morphological evidence. [3] Mitochondrial DNA analysis indicates that E. rufifrons may be more closely related to the common brown lemur (E. fulvus), white-headed lemur (E. albifrons) and Sanford's brown lemur (E. sanfordi) than it is to E. rufus. [3]
The red-fronted lemur lives on the western coast of Madagascar between the Tsiribihina River to the north and south of the Fiheranana River and in eastern Madagascar from the Mangoro River and Onive River to the Andringitra Massif. [3] It lives in dry lowland forests. [5] It has a head and body length of 35 to 48 centimetres (14 to 19 in) and with a 45 to 55 centimetres (18 to 22 in) tail. [5] Its weight ranges between 2.2 and 2.3 kilograms (4.9 and 5.1 lb). It has a gray coat and black face, muzzle and forehead, plus a black line from the muzzle to the forehead, with white eyebrow patches. [5] Males have white or cream colored cheeks and beards, while females have rufous or cream cheeks and beards that are less bushy than males. [5]
There is considerable geographic variation in the natural history of this species. Western populations tend to have smaller home ranges and higher population densities than eastern populations, although group size tends to be fairly consistent (generally 4–18 animals, averaging 8–9). [5] None of the studied populations show dominance hierarchies and aggression tends to be low. [5]
Diet is diverse, encompassing leaves, seeds, fruit, nectar and flowers, but more so in eastern populations. Western populations tend to rely more on leaves for their diet. [5] Western populations are primarily diurnal, but increase nocturnal activity during the dry season, while eastern populations show less such dichotomy. [5]
Reproduction is seasonal. In western populations one male usually monopolizes all the females in the group, while in eastern populations such monopolization is less typical. [5]
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.
The ring-tailed lemur is a medium- to larger-sized strepsirrhine (wet-nosed) primate, and the most internationally-recognized lemur species, owing to its long, black-and-white, ringed tail. It belongs to Lemuridae, one of five lemur families, and is the only member of the Lemur genus. Like all lemurs, it is endemic to the island of Madagascar, where it is endangered. Known locally in Malagasy as maky or hira, it ranges from gallery forests to spiny scrub in the southern regions of the island. It is omnivorous, as well as the most adapted to living terrestrially of the extant lemurs.
True lemurs, also known as brown lemurs, are the lemurs in genus Eulemur. They are medium-sized primates that live exclusively on Madagascar.
The red-bellied lemur is a medium-sized strepsirrhine primate with a luxuriant chestnut brown coat. This lemur is endemic to eastern Madagascan rainforests and is distinguished by patches of white skin below the eyes, giving rise to a "teardrop" effect, particularly conspicuous in the male.
The crowned lemur is a lemur that is 31–36 cm (12–14 in) long and weighs 2 kg (4.4 lb). Its tail is about 42–51 cm (17–20 in) long.
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 diademed sifaka, or diademed simpona, is an endangered species of sifaka, one of the lemurs endemic to certain rainforests in eastern Madagascar. Along with the indri, this species is one of the two largest living lemurs, with an average weight of 6.5 kg and a total adult length of approximately 105 centimetres (41 inches), half of which is its tail. Russell Mittermeier, one of the contemporary authorities on lemurs, describes the diademed sifaka as "one of the most colorful and attractive of all the lemurs", having a long and silky coat. P. diadema is also known by the Malagasy names simpona, simpony and ankomba joby. The term "diademed sifaka" is also used as a group species designation formerly encompassing four distinct subspecies.
The blue-eyed black lemur, also known as the Sclater's lemur, is a species of true lemur. It can attain a body length of 39–45 cm (15–18 in), a tail length of 51–65 cm (20–26 in), a total length of 90–100 cm (35–39 in), and a weight of 1.8–1.9 kg (4.0–4.2 lb). Being a primate, it has strong hands with palms like a human, which have a rubbery texture to give it a firm grip on branches. Its tail is longer than its body and is non-prehensile.
The common brown lemur is a species of lemur in the family Lemuridae. It is found in Madagascar and has been introduced to Mayotte.
The white-headed lemur, also known as the white-headed brown lemur, white-fronted brown lemur, or white-fronted lemur, is a species of primate in the family Lemuridae. It is only found in north-eastern Madagascar. It is arboreal and is usually found in rainforest treetops. It was formerly recognised as a subspecies of the common brown lemur.
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.
Sanford's brown lemur, or Sanford's lemur, is a species of strepsirrhine primate in the family Lemuridae. Sanford's brown lemur was previously considered a subspecies of the common brown lemur but was raised to full species in 2001. It is named after Leonard Cutler Sanford, a trustee of the American Museum of Natural History.
Tampoketsa Analamaitso Reserve is a wildlife reserve of Madagascar located in the Sofia Region. It covers 17 150 ha in three districts: Port Bergé, Mandritsara and Mampikony.
The gray-headed lemur, 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. It lives in south-eastern Madagascar. In 2005, satellite imagery estimates showed approximately 700 km2 (270 sq mi) of total remaining habitat within its geographic range. It is highly threatened by hunting and habitat loss, and was considered to be among the 25 most endangered primates in 2006–2008. It is currently listed as Critically Endangered by the International Union for Conservation of Nature (IUCN) due to a highly restricted range, and has been named one of "The World's 25 Most Endangered Primates."
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.
