Seal's sportive lemur (Lepilemur seali), or the Anjanaharibe-Sud sportive lemur, is a sportive lemur endemic to Madagascar. [4] Previous to a 2006 genetic analysis showing the species to be distinct, it was thought to be a population of weasel sportive lemur (Lepilemur mustelinus). [5] Like all members of its genus, it is nocturnal and largely folivorous. It is threatened by habitat loss, hunting, and climate change. [1]

Evolution

Seal's sportive lemur is a sister species to Holland's sportive lemur (Lepilemur hollandorum), having diverged approximately 2.1 million years ago. These two species further fall into a northeastern Lepilemur clade with Scott's sportive lemur (Lepilemur scottorum) that originated approximately 2.68 million years ago. [6]

Description

Seal's sportive lemur has long, thick fur that is uniformly light chocolate-brown to reddish-brown above and lighter brownish grey below with cream-tipped hairs on the sides of the belly. The face is light brownish grey, with a yellow to white collar on the neck. The hands and feet are light, greyish brown. The tail is brownish grey, and sometimes possesses white-tipped hairs. It is a medium-sized Lepilemur, with a total length of 53 cm (21 in), of which 27 cm (11 in) is the body and 26 cm (10 in) is the tail. It weighs approximately 950 g (34 oz). [5]

Distribution and habitat

Seal's sportive lemur is found in northeastern Madagascar, where it is known at least as far south as the Fananehana River and no farther north than the Bernarivo River. However, the exact boundaries of the species' range are not clear. Within its distribution, Seal's Sportive Lemur occupies mid to high altitude humid rainforests, preferring undisturbed low-canopy forests that have good availability of sleeping holes in old trees. [4]

Threats and conservation

The main threats facing Seal's sportive lemur are habitat loss, hunting and climate change. The rainforests in which the species inhabit are under direct threat due to forest clearing for shifting agriculture. Additionally, hunting of the species is unsustainable, with local households on average hunting 0.15 Seal's sportive lemurs per year, among 1,155 households in the surveyed region. [4] The species' distribution is also expected to shrink by 8% by 2080 due to climate change alone. [7]

Seal's sportive lemur occurs in some protected areas such as the Anjanaharibe-Sud Special Reserve and Makira Natural Park. [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.

The weasel sportive lemur, 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. Described by Isidore Geoffroy Saint-Hilaire in 1851, it is the type species of genus Lepilemur. It is threatened by habitat loss, climate change and hunting.

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.
