Northern sportive lemur (Lepilimur sapentrionalis), also known as co-sportive lemur or northern weasel lemur, is a species of lemur in the Lepilimuridae family. It is native to Madagascar. As a result of severe ecological and human stress, lemur has been classified as critically endangered (CR) by the IUCN Red List and is one of the most endangered primate species in the world.
L. Septentrionalis is a sportive lemur, so it is named for lemur because of its boxing-like stance when threatened. The Northern Sportive lemurs grow to a height of about 53 cm (21 inches). Their head and body length and tail lengths are 25 and 28 cm (9.8 and 11.0 inches), respectively, and the average weight is 0.7 to 0.8 kg (1.5 to 1.8 pounds) on average.
Their smaller size makes them one of the smallest species in the genus Lepillimore. Their ears are also comparatively less prominent than other Lepilimura species. They have a gray bottom and their fur coat is of a gray-brown color, which is removed from the crown to the bottom of the crown and the bottom of the dorsal line to a dark gray stripe, the ends of the pump and the ends being a bluish-gray.
The lemurs are firmly drawn on the branches of the tree, using an extended and fleshy digital pad on the hands and feet, often holding a steep vertical posture. Lemurs can jump from this vertical position, making them a clever arboreal species. The big eyes in front of them give the telescopic vision of the lemurs.
Distribution and Accommodation
Northern sportive lemurs live in a very limited range in northern Madagascar. The species is located off the left bank of the Loki River.
The natural habitat of the species consists of a small mountain that rises in the north of the Irfu river, in the vicinity of Madirob and Ankarangana villages in the Sahafari region and in the vicinity of Andhrahona, a small mountain that lies low in the south of Antesirana.
Northern Sportive lemons are nocturnal, pack for dinner and sleep during the day. Lemurs sleep in holes or thick leaves of trees from 1 to 8 meters (3.3 to 26.2 feet). Women will leave their babies in a branch while feeding for food.
Males are lonely and territorial, and their territories often overlap with many female home ranges. Male lemurs will aggressively protect their territories during the mating season.
Men are generally considered to be transparently polygons, but it has been suggested that men may be exclusive. L. Sepentrionalis individuals communicate via chemical contact in the form of latrine behavior to identify the region, as well as by vocal communication (call).
There are two main calls: a call like a high crow and a rejection call. The higher call is used by lemurs to express their presence and regional claim to other people.
The rejection call is a series of resonant heresies after two-stage vocalization, most commonly heard when two people approach each other in the wild.
When the detainees came in contact with each other while in captivity, the call to refuse contact was also heard, at which point they could hit each other with their hands.
Northern Sportive Lemur is characterized by native Malagasy tree boa, which preys on lemons to sleep in tree trunks. Large birds of prey, falcon form, and strigiform are also natural predators of lemurs.
In addition to these environmental threats, species of arterial lemurs are greatly threatened by human charcoal production, which is still removing the only remaining forest of lemurs, greatly limiting their range.
El Sapentrionalis was also illegally hunted as bushmeat. The combination of these threats has reduced the population of the lemurs by just a few hundred, according to estimates from the IUCN Red List. These are categorized as critically endangered under the IUCN Red List
Virtually all of these are declining dramatically in the population, mostly because entering the forest where they live may result in loss of habitat – but also because of poaching.
Many lemur species are listed as endangered or critically endangered by the International Union for Conservation of Nature (IUCN).
The known habitat range of the lemurs is not continuous with any protected areas, and although Madras is considered sacred to the Underhona Forest, it shows signs of human intrusion.
