Hawks' sportive lemur (Lepilemur tymerlachsoni), also known as the Nosy Be sportive lemur or Nosy Be weasel lemur,[ citation needed ] is a sportive lemur endemic to Madagascar. Like all members of its genus, it is solitary, nocturnal and largely folivorous. It is threatened by habitat loss and unsustainable hunting. [1]

Taxonomy and phylogenetics

Hawks' sportive lemur was described in 2006 based on genetic samples and morphometrics collected in 2003 and 2004. The specific epithet tymerlachsoni honors the Howard and Rhonda Hawk family. [3]

The name was corrected to L. tymerlachsonorum in 2009 under the incorrect assumption that the name was based on a husband and wife team. [4] The original form is therefore considered the correct version. [1]

Genetic analyses show Hawks' sportive lemur to be an outgroup to a clade containing the Ankarana sportive lemur and the Daraina sportive lemur. [5]

Description

Lepilemur tymerlachsoni Lokobe 510.jpg

Hawks' sportive lemur is light brownish-gray with the upper half of the back a lighter reddish-brown. The underside is a light grayish-white. The outer side of the thighs and edges of the extremities also have a light reddish-brown color. A dark brown to black stripe is present from the head to the lower half of the back. The face is gray. The tail is a uniform light reddish-gray to brown. [3]

It is a moderately large sportive lemur, with a total length of about 50 to 68 cm (20 to 27 in), of which 22 to 27 cm (8.7 to 10.6 in) is the tail. [6]

Distribution and habitat

Hawks' sportive lemur is endemic to Nosy Be island, Madagascar, where it is only known from Lokobe National Park and adjacent degraded forest. [1] [7] It is estimated to occupy an area of less than 72 km2 and occurs from 12-35 metres above sea level. [1] Within Lokobe National Park, it has been recorded to achieve an average density of 63.2 individuals/km2. [8]

The main forest type within its range is lowland rain forest, although the region experiences a distinct dry season. [1]

Selection of daytime sleeping spots change according to habitat type, with individuals favoring tree holes in dense primary forest and dense vegetation tangles in more open deciduous forest. [9]

Threats and conservation

Hawks' sportive lemur is threatened by forest degradation and clearing for agriculture and timber resource extraction. Additionally, it is locally hunted at an unsustainable rate, and captured individuals have been recorded being sold to tourists. To combat loss of suitable habitat, nest boxes have been placed in degraded forest areas. [1]

<span class="mw-page-title-main">Sportive lemur</span> Genus of lemurs

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 native to northeastern Madagascar. Its habitat includes rainforests and tropical rainforests. Its dorsal side is a reddish-brown colour, and greyish brown ventrally. Its colour darkens towards the tip of its tail. Individuals weigh from 0.8 to 1.2 kg It has long, soft fur. Its body length is approximately 22–30 cm (8.7–11.8 in) and a tail length of 23–27 cm (9.1–10.6 in).

<span class="mw-page-title-main">White-footed sportive lemur</span> Species of lemur

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.

<span class="mw-page-title-main">Small-toothed sportive lemur</span> Species of primate from Madagascar

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.
