The aye-aye, mouse lemurs, woolly lemurs, and sportive lemurs are nocturnal, while ring-tailed lemurs and most of their kin, sifakas, and indri are diurnal. Fork-marked lemurs either consume the gum as it seeps from cracks in the bark of parasitized trees or gouge open the bark with their toothcomb to scoop it up directly with their long tongue. Their diet consists primarily of tree gum and other exudates, though they may obtain some of their protein and nitrogen by hunting small arthropods later at night. Their face and stripe actually reminds me of slow lorises. Scientific Collections ... Name Homonyms Phaner furcifer (de Blainville, 1839) Common names ...

Although it is best to organise a visit to the reserve in Diego Suarez, guides and porters can alternatively be found in Menagisy, a village next to the reserve.. The average size of a female territory is 4 hectares (9.9 acres) with a male territory averaging 3.8 hectares (9.4 acres). The Pale Fork-marked Lemur is an arboreal, nocturnal primate, that lives in the dry wes tern forests of. HABITAT: rainforest. The collection grows regularly with specimens collected during scientific expeditions and animals from zoological parks (Zoo de Vincennes, Ménagerie du Jardin des Plantes, Parc de la Haute-Touche) or care centers. Like the other members of their family, they are nocturnal, and sleep in tree holes and nests during the day. [25][26], Of the mostly small, nocturnal lemurs in family Cheirogaleidae, the genus Phaner contains some of the largest species, along with Cheirogaleus. Black lemur ... Gray mouse lemur. [6] Only the pale fork-marked lemur (P. pallescens) has been studied relatively well, primarily by Pierre Charles-Dominique, Jean-Jacques Petter, and Georges Pariente during two expeditions in the 1970s and a more extensive 1998 study in Kirindy Forest. The ring-tailed lemur (Lemur catta) is a lairge strepsirrhine primate an the maist recognised lemur due tae its lang, black an white ringed tail.

Filter by field site . Three of the four species are endangered and the other is listed as vulnerable. Family Cheirogaleidae consists of the mouse lemurs (smallest of all primates), the dwarf lemurs, and the fork-marked lemurs and their allies. This remains in the nesting hole of the parents at first, but as it gets older it is carried by the mother, clinging to her underside, and when it gets larger, to her back. [45], To meet their protein requirements and obtain nitrogen, these lemurs also hunt small arthropods. [49], Males and females have been seen sleeping and foraging together as monogamous pairs, although polygamy and solitary behavior has also been observed.

Like all lemurs, they are protected against commercial trade under CITES Appendix I. Fork-marked lemurs were first documented in 1839 by Henri Marie Ducrotay de Blainville when he described the Masoala fork-marked lemur (P. furcifer) as Lemur furcifer. The “ true lemurs” (family Lemuridae) include five genera and about 20 species. Like most lemuriform primates, it has a toothcomb; in Phaner species, the toothcomb has evolved to be more robust and is used to scrape the gum that exudes from holes on a tree made by insects. Scientific Name: Lemur catta. Filter by scientific name . There are 37 extant species. [6][13] In 2001, Groves elevated all four subspecies to species status[6][14] based on noticeable color, size, and body proportion differences between the fragmented populations. KingdomAnimaliaanimals. [18], Fork-marked lemurs were called "fork-marked dwarf lemurs" by Henry Ogg Forbes in 1894 and "fork-crowned mouse lemur" by English missionary and naturalist James Sibree in 1895. [44], Other nocturnal lemurs are sympatric with fork-marked lemurs. [24] If correct, this would make the family Cheirogaleidae paraphyletic. The gray mouse lemur is one of as many as 21 tiny, nocturnal mouse lemur species. [44] Territory overlap is minimal between males, and the same pattern is seen in females, though males and females may overlap their territories. Since the genera Mirza (giant mouse lemurs) and Azema (for M. rufus, now a synonym for Microcebus) were both described in the same publication and equally enigmatic, the authors concluded that Gray had seen the comedy and then based the names of three lemur genera on its characters.

[44] During social grooming (allogrooming), the male allomarks females using a scent gland on the throat,[51] and grooming sessions can last several minutes. [42] Studies of P. pallescens at Kirindy Forest found up to a 20% drop in body mass during the dry season despite no changes in exudate production, indicating flowers and insects have a significant impact on the species' health. Measures of their population density vary widely, from 50 to 550 individuals per square kilometer (250 acres), but these numbers are thought to reflect only small, gum-rich areas, and therefore only small, clustered populations with an overall low population density. A large cutaneous gland on the throat of the male is used during social grooming when males, females and juveniles groom each other, and the male may rub the gland on the female. Because of their fast movement, individuals can easily defend their territories by traversing it within 5 minutes. MORE IN LEMUR CATEGORY. [36] The offspring may remain under the care of their parents for three years or more,[44] and there is no information about their dispersal at maturity. The animal's faeces are invariably found to contain fragments of insect chitin. [36] Unlike other lemurs, fork-marked lemurs do not scent-mark, and instead use vocalizations during territorial confrontations. (unpubl.) ...

In 1904, Theodore Sherman Palmer attempted to document the etymologies of all mammalian taxa, but could not definitively explain the origins of the generic name Phaner, noting only that it derived from the Greek φανερός (phaneros) meaning "visible, evident". [48] They are considered very vocal animals, and have a complex range of calls. It is a small nocturnal animal with large eyes, greyish fur and a long tail. Its body plus head length measures 23 to 29 cm, and the tail is 29 to 36 cm long. [4], This species is nocturnal and has a territory containing about three exclusive Terminalia trees and access to about nine more in overlapping territories. [6] On average, males make approximately 30 loud calls per hour,[37][43] and are most vocal at dusk and dawn. They are named for the two black stripes which run up from the eyes, converge on the top of the head, and run down the back as a single black stripe. Genus Phaner fork-marked lemur.

[5], This lemur is endemic to northeastern Madagascar. Malagasy: Tanta. [4], Gum is low in nitrogen content, and the Masoala fork-marked lemur needs to supplement its diet with animal prey, which it stalks on the tree bark and among the foliage, catching it with its hands and stuffing it into its mouth. The same Terminalia trees are exploited by day by a bird, the crested coua (Coua cristata), which also feeds on gum. Competition with other cheirogaleids, such as the gray mouse lemur (Microcebus murinus) and Coquerel's giant mouse lemur (Mirza coquereli), is most intense for Terminalia gum during the dry season, but fork-marked lemurs always drive the other lemur species off. d'Ambre Fork-crowned Lemur Discover How Long Sahafary Sportive Lemur Lives ...

Phaner electromontis is a light gray species of fork-marked lemur. The two cusps on the last upper premolar (P4) are a large paracone and a smaller protocone. In October, a specimen was observed, captured, and released, although genetic tests have yet to determine if it is a new species. Phaner electromontis (Amber Mountain Fork Marked Lemur) is a species of primates in the family Cheirogaleidae. Females have a narrow, bare patch of white skin in the same location, but theirs does not appear to produce secretions. [10] In 1870, John Edward Gray assigned fork-marked lemurs to their own genus, Phaner,[6] after initially including them and the mouse lemurs in the genus Lepilemur (sportive lemurs). Fork-marked lemurs or fork-crowned lemurs are strepsirrhine primates; the four species comprise the genus Phaner. Family: Cheirogaleidae. green = P. pallescens[3] The fork-marked dwarf lemur (P. furcifer) is about the same size as the greater dwarf lemur (C. major) and somewhat larger than the fat-tailed dwarf lemur (C. medius). Category: Lemur. Red Ruffed Lemur. [4] The female comes into estrus for three to four days in June, giving birth to a single offspring in November or December.
