The weasel sportive lemur (Lepilemur mustelinus), also known as the greater sportive lemur, weasel lemur, or greater weasel lemur, is a species of lemur endemic to Madagascar. Like all members of its genus, it is nocturnal and largely folivorous. [4] Described by Isidore Geoffroy Saint-Hilaire in 1851, it is the type species of genus Lepilemur. [5] It is threatened by habitat loss, climate change and hunting. [1]

Evolution

Phylogenetic studies show that the weasel sportive lemur diverged from its closest relatives, the Betsileo sportive lemur (L. betsileo) and James' sportive lemur (L. jamesi), approximately 1.18 million years ago. These three species are further nested within a clade containing all the Lepilemur species that inhabit Madagascar's eastern rainforests, with the exception of the small-toothed sportive lemur (L. microdon). [6]

Description

The weasel sportive lemur has long, dense fur that is chestnut-brown on the back, often displaying a dark midline stripe. The face is gray or brown, with the cheeks, throat and abdomen slightly lighter. The tail darkens towards the tip. There have also been reports of bright orange morphs in otherwise normally colored populations. [4] It is a relatively large Lepilemur, with a total length of 51–59 cm (20–23 in), of which 26–30 cm (10–12 in) is the body and 25–29 cm (9.8–11.4 in) is the tail. [4] [7] It weighs 0.8–1.2 kg (1.8–2.6 lb). [8]

Distribution and habitat

The weasel sportive lemur inhabits montane and lowland rainforests in eastern Madagascar, from south of the Nosivolo and Mangoro rivers, north to at least the Maningory River. However, Additional work is needed to determine the exact limits of its distribution. Within this range, it is known to occur in Analamazoatra National Park, Mantadia National Park, Zahamena National Park, Mangerivola Special Reserve, Betampona Strict Nature Reserve, Zahamena Strict Nature Reserve, and Tsinjoarivo Classified Forest. The species' estimated extent of occurrence is 18,661 km2 (7,205 sq mi). [4]

The weasel sportive lemur has been reported to occupy territories of 1.5 ha (3.7 acres), with population density estimated at 3 to 5 individuals/km2 in some areas. During the dry season it sleeps in tree cavities 6–12 m (20–39 ft) above the ground and in vine tangles and leaves during the wet season. Its diet is composed primarily of leaves, but also flowers and fruits. The weasel sportive lemur competes for food with the eastern woolly lemur (Avahi laniger), another nocturnal lemur that primarily feeds on leaves. The two species therefore partake in niche partitioning, with the eastern woolly lemur feeding on leaves of high nutritional value and the weasel sportive lemur subsisting on leaves of lower nutrition and high alkaloid content. [4]

Threats and conservation

The main threats facing the weasel sportive lemur are habitat loss, hunting and climate change. The rainforests in which the species inhabit have lost approximately 30% of their tree cover over the last three generations of the species and appears to be accelerating. Bushmeat hunting also poses a threat, and weasel sportive lemurs are hunted at a rate of 0.02 individuals per household per year in surveyed areas of their distribution. [1] Additionally, climate change is expected to reduce the weasel sportive lemur's distribution by 3% by 2080 through habitat alteration. [9] While no species-specific conservation actions have been implemented, the species is known to occur in multiple national parks and other reserves. [4]

The sportive lemurs are the medium-sized primates that make up the family Lepilemuridae. The family consists of only one extant genus, Lepilemur. They are closely related to the other lemurs and exclusively live on the island of Madagascar. For a time, this family was named Megaladapidae, but the current name was given precedence since the extinct genus Megaladapis was removed from the family.

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

The eastern woolly lemur, also known as the eastern avahi or Gmelin's woolly lemur, is a species of woolly lemur native to eastern Madagascar, where it lives in the wet tropical rainforest at low elevations along the eastern coast of the island or they can also inhabit the northern tip of the island with other species. The woolly lemur name refers to their thick, tightly curled hair, whereas their generic name avahi refers to their high-pitched defensive call. The eastern woolly lemur almost has an owl-look with its large eyes, small rounded head, and ears that are mostly hidden. This nocturnal animal weighs 1.0–1.3 kg (2.2–2.9 lb) and reaches a length of 27–29 cm (11–11 in) with a tail of 33–37 cm (13–15 in). Its diet consists mainly of leaves and buds with fruits, flowers, and bark.

The white-footed sportive lemur, white-footed weasel lemur, or dry-bush weasel lemur is a species of lemur in the family Lepilemuridae, the sportive lemurs. It is similar in appearance to other lemurs in the family, with a grey back, a pale grey to white ventral side, and a light brown tail. It is a nocturnal animal that moves through the forest using a vertical clinging and leaping technique. It is endemic to Madagascar, inhabiting the southern subtropical or tropical dry shrubland. It is threatened by habitat loss due to agriculture practices and charcoal production.

The small-toothed sportive lemur, or small-toothed weasel lemur, is a primate species in the family Lepilemuridae that—like all extant lemurs—is endemic to Madagascar. The species lives in dense rainforest in southeastern Madagascar, and can be found in Ranomafana and Andringitra National Parks. Described in 1894, it was considered either a subspecies or taxonomic synonym of the weasel sportive lemur throughout most of the 20th century. Phylogenetic studies not only support its species status, but also suggest that it is the only eastern Malagasy sportive lemur that is more closely related to western than to other eastern species.
