In western Madagascar, interspecific competition is reduced by restricting activity to specific levels of the canopy, such as using only the highest sleeping sites at least 8 m (26 ft) above the ground. Its body plus head length measures 23 to 29 cm, and the tail is 29 to 36 cm long. [41], Fork-marked lemurs are among the least studied of all lemurs, and little is known about them. The head-and-body length is in the range 227 to 285 mm (9 to 11 in), with a tail of 285 to 370 mm (11 to 15 in). 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. [43] In one case, a family of fork-marked lemurs exhibited mobbing behavior when they encountered a Malagasy tree boa. Tattersall (1982) reported head-body lengths ranging from 23–29 cm and tail lengths from 29–37 cm. Like other cheirogaleids, their first lower premolar (P2) is caniniform and large, while the cingulids (ridges) on the three lower premolars are more developed compared to most other cheirogaleids. Common Name: Masoala Fork-marked Lemur. [6][54] Their diet consists mainly of gum from trees in the genus Terminalia (known locally as "Talinala"),[6][42][55] which are often parasitized by beetle larvae that burrow beneath the bark. [6], In December 2010, Russell Mittermeier of Conservation International and conservation geneticist Edward E. Louis Jr. announced the possibility of a new species of fork-marked lemur in the protected area of Daraina in northeast Madagascar. [44] Nest sharing among pairs occurs one out of every three days. Females have a narrow, bare patch of white skin in the same location, but theirs does not appear to produce secretions. This species has a dark ring around each eye. 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. [35] The next upper premolar (P3) is very small,[14] with a single, pointed cusp that contacts the lingual cingulum (a crest or ridge on the tongue side), which circles the base of the tooth. Phaner Gray, 1870 – fork-marked lemurs : Direct Children: Species: Phaner electromontis Groves and Tattersall, 1991 – Montagne d'Ambre Fork-marked Lemur, Mt. Since then, the "fork-marked" prefix has become more widely used. [21] One uniting characteristic (synapomorphy) among all cheirogaleids, to the exclusion of other lemurs, is the branching of the carotid artery along with how it enters the skull[22]—a trait which is shared by fork-marked lemurs. Fork-marked Lemur. [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. A division of labor in muscles: Functinal comparison of medial gastrocneumius and soleus in Lemur and Loris. This lemur typically weighs between 300 and 500 g (11 and 18 oz). Both patterns of sexual dimorphism are consistent with the theory of sexual selection for monogamous species and female dominance respectively. Pariente's fork-marked lemur (Phaner parienti), or the Sambirano fork-marked lemur is a species of lemur endemic to the Sambirano region of north-western Madagascar.This lemur has light brown to gray upperparts, a prominent facial fork and dorsal stripe that runs from the tail's tip to the point where it splits on the lemur's head to rejoin at the nose, and a white-tipped tail. Category: Lemur. [23] Broad agreement between two lemur phylogeny studies—one in 2004 using SINE analysis and another in 2012 using multilocus phylogenetic tests—gave strong support for a sister group relationship between fork-marked lemurs and the rest of the cheirogaleids and a more distant relationship with sportive lemurs. Interlimb coordination and gait in the brown lemur (Lemur fulvus) and the talapoin monkey (Miopithecus talapoin). If the brown mouse lemur reminded you even a smidgen of the sugar glider, then the fork-marked lemur must look like the sugar glider's twin! Red Brown Lemur. [19], A study in 2009 of seven mitochondrial genes (mtDNA) and three nuclear genes grouped fork-marked lemurs with sportive lemurs (family Lepilemuridae), offering a host of explanations, such as a possible hybridization (introgression) following the initial split between the families. Cold temperatures can also cause individuals to retire to their sleeping site as early as two hours before dawn. Scientific name: Latin binomial name, or Latin name, of the species : ... Family Cheirogaleidae consists of the mouse lemurs (smallest of all primates), the dwarf lemurs, and the fork-marked lemurs and their allies. Category: Lemur. For gripping tree trunks and large branches, they have large hands and feet with extended pads on the digits, as well as claw-like nails. The species is named after the Amber Mountain National Park where they are found. [4] The female comes into estrus for three to four days in June, giving birth to a single offspring in November or December. KingdomAnimaliaanimals. In 2012, the International Union for Conservation of Nature (IUCN) listed P. parienti, P. electromontis, and P. pallescens as endangered, and P. furcifer as vulnerable. Because of their fast movement, individuals can easily defend their territories by traversing it within 5 minutes. Hunting usually occurs later at night, following gum collection, and typically happens in the canopy or on tree trunks. red = P. furcifer[2] Females also make a "bleating" call when they have infants. COMMON NAME: Eastern Fork-Marked Lemur. d'Ambre Fork-crowned Lemur : Species: Phaner furcifer (de Blainville, 1839) – fork-marked lemur, Masoala Fork-crowned Lemur, Masoala Fork-marked Lemur Red Brown Lemur. For a species profile, click on its scientific name. Filter by malagasy name . Category: Lemur. (unpubl.) d Ambre Fork-crowned Lemur in English Mt. CHEIROGALEIDAE Gray, 1873. [46] In areas where territory overlap occurs ("meeting areas"), several neighbors may gather and vocalize together without aggression. [21] Analyses based on morphology, immunology, and repetitive DNA have given contradictory placements of Phaner, while studies in 2001 and 2008 either lacked data or yielded poor resolution of their placement. Fork-marked lemur-Wikipedia. If shown to be a new species, they plan to name it after Fanamby, a key conservation organization working in that protected forest. [35] The molars are relatively small compared to other cheirogaleids, with the second upper and lower molars (M2 and M2) having reduced functionality compared to those of mouse lemurs. 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. [37][36][47] Multiple family groups may gather in these meeting areas, and females will often socialize with the other females and young. Discover How Long Brown lemur Lives. 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. Fork-marked lemurs or fork-crowned lemurs are strepsirrhine primates; the four species comprise the genus Phaner. Red Brown Lemur. Masoala Fork-crowned Lemur area.png 180 × 360; 3 KB Phaner furcifer - 1868 - Print - Iconographia Zoologica - Special Collections University of Amsterdam - UBA01 IZ19700028.jpg 1,765 × 2,353; 4 MB Phaner furcifer - AMNH - DSC06355.JPG 3,240 × 4,320; 5.12 MB Family: Cheirogaleidae. Three of the four species are endangered and the other is listed as vulnerable. Malagasy: Tanta. Meaning of Fork-marked lemur. Certain beetle larvae burrow just under the bark of Terminalia and leave characteristic galleries that ooze gum. Following the call. 1985.
