James' sportive lemur (Lepilemur jamesi), or the Manombo sportive lemur, is a sportive lemur endemic to Madagascar. [4] Like all members of its genus, it is nocturnal and largely folivorous. It is threatened by habitat loss and unsustainable hunting. [1]
James' sportive lemur was described in 2006 based on genetic samples and morphometrics collected in 2000 as Lepilemur jamesi. [5] The name was presumed to be incorrectly formed and was corrected in 2009 to Lepilemur jamesorum. [6] However, this change was deemed to be an unjustified emendation. [7] The specific epithet jamesi honors Larry, Jeanette and Barry James for their support of Malagasy graduate students. [5]
Genetic analyses show that James' sportive lemur is a sister species to the Betsileo sportive lemur. [8]
James' sportive lemur possesses short, smooth fur, which is generally brown on the back and lighter grayish-brown on the belly and underside of the extremities. The tail is brown closer to the body, and fades into black towards the tip. The face has whitish-gray markings across the jaw and throat from the chin to the ears, and the top of the head is brown with a black midline that continues down almost the entire length of the body. The ears are gray on the back with black borders, usually with a small cream-colored path directly below on the sides of the face. [4] [5]
James' sportive lemur is medium-sized for its genus. It has a head-body length of 26 cm (10 in) and a tail length of 30 cm (12 in), making its total length 56 cm. It weighs approximately 780 g (28 oz). [4] [5]
James' sportive lemur is found in southeastern Madagascar, where it is known from the Manombo Special Reserve and the Manombo Classified Forest. [4] The exact boundaries of its range are unknown, but the Manampatrana River and the Mananara River have been suggested as potential northern and southern limits. [5] Within its range, James' sportive lemur inhabits one of the last remaining, low-altitude coastal rainforests in the southeast. [4]
The estimated population density of James' sportive lemur in the Manombo Special Reserve and the Manombo Classified Forest are 45 individuals/km2 and 23 individuals/km2, respectively. The total population is approximately 1,386 individuals, as of 2010. [9]
James' sportive lemur is in decline due to habitat loss from shifting agriculture and unsustainable levels of hunting. This decline, in addition to its extremely small distribution, led to its listing as Critically Endangered (CR) on the IUCN Red List in 2020. [1]
James' sportive lemur has appeared twice on the World's 25 Most Endangered Primates list, once in 2017 [10] and again in 2021. [11] As of 2022, it was not being held in captivity. [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.
The northern sportive lemur, also known as the Sahafary sportive lemur or northern weasel lemur, is a species of lemur in the family Lepilemuridae. It is endemic to Madagascar. As a result of severe ecological and human pressures, the lemur is classified as Critically Endangered (CR) by the IUCN Red List.
Wright's sportive lemur, or the Kalambatritra sportive lemur, is a sportive lemur endemic to Madagascar. Like all members of its genus, it is nocturnal and largely folivorous. Unlike all other members of Lepilemur, it displays visible sexual dimorphism. It is threatened by habitat loss.
Fleurette's sportive lemur, or the Andohahela sportive lemur, is a sportive lemur endemic to Madagascar. Like all members of its genus, it is nocturnal, and largely folivorous. It is threatened by habitat loss and hunting.
The Betsileo sportive lemur is a sportive lemur endemic to Madagascar. Like all members of its genus, it is nocturnal and largely folivorous. It is threatened by habitat loss.
Seal's sportive lemur, or the Anjanaharibe-Sud sportive lemur, is a sportive lemur endemic to Madagascar. Previous to a 2006 genetic analysis showing the species to be distinct, it was thought to be a population of weasel sportive lemur. Like all members of its genus, it is nocturnal and largely folivorous. It is threatened by habitat loss, hunting, and climate change.
Hawks' sportive lemur, also known as the Nosy Be sportive lemur or Nosy Be weasel lemur, 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.
Grewcock's sportive lemur, or the Anjiamangirana sportive lemur, is a sportive lemur endemic to Madagascar. It is a medium-sized sportive lemurs with a total length of about 55 to 63 cm, of which 26–30 cm (10–12 in) are tail. Grewcock's sportive lemur is found in northwestern Madagascar, living in dry deciduous forests.
Ahmanson's sportive lemur, or the Tsiombikibo sportive lemur, is a sportive lemur endemic to Madagascar. It is a relatively small sportive lemur with a total length of about 47 to 54 cm, of which 23–25 cm (9.1–9.8 in) are tail. Wright's sportive lemur is found in western Madagascar, living in dry forests.
Randrianasolo's sportive lemur, or the Bemaraha sportive lemur, is a sportive lemur endemic to a small area of western Madagascar. It is threatened by habitat loss.
Hubbard's sportive lemur, or the Zombitse sportive lemur, is a sportive lemur endemic to Madagascar. It has total length of about 51 to 59 cm, of which 23–25 cm (9.1–9.8 in) are tail. Hubbard's sportive lemur is found north of the Onilahy River and south of the Mangoky River in Zombitse-Vohibasia National Park in southwestern Madagascar, living in dry transitional forests. The species listed as endangered by the International Union for Conservation of Nature (IUCN) and is threatened by habitat loss and degradation, forest fires, and unsustainable levels of hunting.
Petter's sportive lemur is a sportive lemur endemic to Madagascar. It is one of 26 species in the genus Lepilemur. It is one of the smaller sportive lemurs with a total length of about 49 to 54 cm, of which 22–25 cm (8.7–9.8 in) are tail. Petter's sportive lemur is found in southwestern Madagascar, living in dry spiny forests and some gallery forests.
The Daraina sportive lemur is a sportive lemur endemic to Madagascar. It is a relatively small sportive lemur with a total length of about 49 to 56 cm, of which 24–27 cm (9.4–10.6 in) are tail.
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."
Jean-Jacques Petter (1927-2002) was a French primatologist known for his studies of lemurs and his conservation work in Madagascar.
