The mongoose lemur (Eulemur mongoz) is a small primate in the family Lemuridae, native to Madagascar and introduced to the Comoros Islands. These arboreal animals have pointed faces, long, bushy tails, dark-brown upper parts, pale bellies, and beards, which are reddish in males and white in females. They live in family groups and feed primarily on fruit, but also eat leaves, flowers, and nectar, with nectar from Ceiba pentandra trees making up a large part of their diet during the dry season. They have declined sharply in numbers because of habitat destruction and hunting, and the International Union for Conservation of Nature has rated their conservation status as "critically endangered".

Description

The mongoose lemur ranges in size from 12 to 18 in (300 to 460 mm) long plus a tail of 16 to 25 in (410 to 640 mm). Both sexes are born with white beards, but become obviously dimorphic around six weeks of age when the males develop red beards and red cheeks. The males also have lighter faces than the females. [4] Males may further distinguish themselves when scent-marking territory, as they occasionally develop a bald patch on top of their heads from rubbing. [5]

Distribution

The mongoose lemur lives in dry deciduous forests on the island of Madagascar and in the humid forests on the islands of the Comoros. This makes the mongoose lemur one of only two lemurs found outside of Madagascar, [4] though it is an introduced species in the Comoros. [6] [7]

Ecology

The mongoose lemur mostly eats fruit, though flowers, leaves, and nectar also make up part of its diet; (they may use the nectar of the non-native kapok tree, Ceiba pentandra [lower-alpha 1] for nearly eighty percent of their diet during the dry season in some parts of their range). [10] As such, mongoose lemurs act as both pollinators and seed dispersers. [4] Feeding on grubs and beetles has also been observed. [6] They are unusual among primates in that they are diurnal or nocturnal, depending on the season, being more active during the day in the wet season and changing activity to the night during the hotter dry season. [4]

Mongoose lemurs are arboreal, with the ability to jump several meters from one tree to another. [4] They live in small family groups, usually consisting of a bonded pair and one to three offspring. [5] These groups rarely encounter one another, but when they do, they are aggressive. [6] Young are born just prior to the rainy season, from August to October. [6] Gestation lasts about four months and weaning takes place around five months after the young are born. The offspring then usually stay with their parents until three years of age, when they have reached full maturity. [5]

Mongoose lemurs have seasonal habits. Their breeding, eating, and activity habits are largely shaped around the season. Seasonal fluctuations in food resource availability describe the behavior of mongoose lemurs such as female dominance and small group size. Mongoose lemurs usually conceive their offspring some time during October. They present as Nocturnal during the dry season and diurnal during the wet season. [11]

Status

Captive mongoose lemurs can live up to 26 years, while wild specimens live 18–20 years. [5] Mongoose lemurs in the wild are threatened by the destruction and fragmentation of the forests in which they live, and also by hunting. Their numbers have dwindled by about 80% over a period of 25 years, and the International Union for Conservation of Nature has rated their conservation status as "critically endangered". [1] Mongoose lemurs are more endangered in Madagascar, but there could be a way to conserve them in Comoros because of the increase of these species' population in the area. [12]

Notes

  1. C. pentandra, although not native to Madagascar have been used for reforestation on the island. [8] [9]

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.

<span class="mw-page-title-main">Lemur</span> Clade of primates endemic to the island of Madagascar

Lemurs are wet-nosed primates of the superfamily Lemuroidea, divided into 8 families and consisting of 15 genera and around 100 existing species. They are endemic to the island of Madagascar. Most existing lemurs are small, have a pointed snout, large eyes, and a long tail. They chiefly live in trees and are active at night.

<span class="mw-page-title-main">Gray mouse lemur</span> Small primate from Madagascar

The gray mouse lemur, grey mouse lemur or lesser mouse lemur is a small lemur, a type of strepsirrhine primate, found only on the island of Madagascar. Weighing 58 to 67 grams, it is the largest of the mouse lemurs, a group that includes the smallest primates in the world. The species is named for its mouse-like size and coloration and is known locally as tsidy, koitsiky, titilivaha, pondiky, and vakiandry. The gray mouse lemur and all other mouse lemurs are considered cryptic species, as they are nearly indistinguishable from each other by appearance. For this reason, the gray mouse lemur was considered the only mouse lemur species for decades until more recent studies began to distinguish between the species.

<span class="mw-page-title-main">Black lemur</span> Species of lemur

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 species is listed as Endangered by the International Union for Conservation of Nature (IUCN) and is threatened primarily by habitat loss.

<span class="mw-page-title-main">Red-fronted lemur</span> Species of lemur

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.

Milne-Edwards's sifaka is characterized by a black body with a light-colored "saddle" on the lower part of its back. It is closely related to the diademed sifaka, and was until recently considered a subspecies of it. Like all sifakas, it is a primate in the family Indriidae.

<span class="mw-page-title-main">Black-and-white ruffed lemur</span> Species of lemur

The black-and-white ruffed lemur is an endangered species of ruffed lemur, one of two which are endemic to the island of Madagascar. Despite having a larger range than the red ruffed lemur, it has a much smaller population that is spread out, living in lower population densities and reproductively isolated. It also has less coverage and protection in large national parks than the red ruffed lemur. Three subspecies of black-and-white ruffed lemur have been recognized since the red ruffed lemur was elevated to species status in 2001.
