Ruffed lemur of the Varecia species is the largest largest Strepsirrine primate and in the Laburidae family. Like all living lemurs, they are only found on Madagascar Island. Formerly considered a monolithic genus, two species are now recognized: black-and-white lemur, which has three subspecies and red ruffed lemur.
Where are Ruffed Lemur found?
Ruffed lemur is denial and arboreal quadrant, often leaping through the upper canopy of eastern Madagascar’s seasonal tropical rainforest. Ruffed lemur is also the smallest of the Malagasy lemurs and is very sensitive to habitat disturbance.
A ruffed lemur lives in many male / multi-female groups and has a complex and flexible social structure, described as fission-fusion. These are extremely vocal and loud, provocative calls. (source)
Ruffed lemurs are seasonal breeders and are extremely unusual in their breeding strategies. They are regarded as an “evolutionary lizard” in that they are the largest of the species present in Laburidae, yet the reproductive traits are more common in small, nocturnal legumes, such as shorter gestation periods (~ 12 days) and relatively larger average litter sizes (~ 2-3).
Ruffed lemurs carry nests for their newborn (the only primate who does this) with their mouths and show their missing parental system when they are grazing. Children are spontaneous, although they develop relatively quickly, travel freely in the wild after 70 days, and attain full adult size within six months.
With the threat of habitat loss and hunting, Ruffed lemur is facing extinction in the wild. However, they reproduce easily in captivity and are reproduced slowly with wilds since 1997.
The organizations involved in conserving ruffed Lemur include Durrell Wildlife Conservation Trust, Lemur Conservation Foundation (LCF), Madagascar Fauna Group (MFG) Organ, Monkland Primate Sanctuary in South Africa, Wildlife Trust and Duke Lemur Hours (dielasi).
Before red ruffed lemurs and black-and-white lemurs, Verasia variegata was recognized as tribal as Rubra and Varesea variegata variegata, respectively. Both were promoted to species status in 2001, a decision that was later backed by genetic research.
Three subspecies of Black-White Roofed Lemur, published decades ago, were also recognized as variegata, editors and subcincta, although studies have not been fully finalized.
Ruffed lemurs are the largest member of the Lemuridae family, with an average head length of 43 to 57 centimeters (17 to 22 inches) and total lengths of 100 to 120 centimeters (39 to 47 inches), weighing from 3.1 to 4.1 kg (6.8 to 9.0 lbs). ).
The dense, animal tail is used for physical length, length 60 and 65 cm (24 and 26 inches) and the balance primarily for balance. Ruffed lemurs do not exhibit sexual dimorphism or sexual dual chromatism, and wives have three pairs of mammary glands.
Ruffed lemurs are characterized by their long, canine-national puzzle, which includes a significant overbite. The face is mostly black, with ferry “ruffs” running from ear to neck.
Depending on the species, these ruffed are either white (V. varigata) or deep red (V. rubra). Similarly, the color of the fluffy beast varies by species, while the color pattern is changed by the subspecies of black and white ruffed lemurs. There is also a mediator of color variation between the two species.
Like all lemurs, the Roofed Lemur is specially adapted for grooming, with the second finger having a toilet nail and a toothbrush.
Ruffed lemurs are considered arboreal quadrilaterals, the most common type of movement being on the quadrangular branch. During canopy jumping, vertical grasping and suspensory behaviors are also common, while bridging, bilateral movements, and bilateral movements are rarely seen.
When moving from tree to tree, the Ruffed lemur will keep an eye on the shoulders, launching themselves into the air and twisting the mid-air so that their ventral surface moves to the new tree or limbs.
Suspended behavior is more pronounced in ruffed lemurs than in other lemurs species. When the ruffed lemurs fall to the ground, they move magnetically, with bounding hops and the tail held high.
Being the most arboreal and the most shrunken of lemurs, they only have many fruit trees in the primary forest where they spend most of their time in the upper camp. Most of their time is spent in the crowns of tall forest trees, they are relatively safe from predators like Phasa.
Ruffed lemurs are primarily active during the day (diurnal), during which they feed primarily on fruits and nectarines, often taking a suspensory posture during feeding. The seeds of the fruits they eat pass through their digestive tract and spread throughout the rainy season in their malls, helping to grow new plants and ensure a healthy forest ecosystem.
These lemurs are also significant pollinators of the trawler tree (Ravenella madagascarinaeis of the foot). They collect and transfer pollen from the tree to the plant and the pollen from the tree, using long rows and tongues deep within the flower, without destroying the flower. This relationship is thought to be the result of co-evolution.
Geographical range and habitat
Like other lemurs, this genus is only found on the island of Madagascar on the southeast coast of Africa. Limited to the island’s seasonal eastern tropical rain forest, it is rare throughout its range, which flows from the Masawala Peninsula in the northeast to the Mananara River in the south.
Today, the black-and-white ruffed lemur is much larger than the red lemurs, though very complex, extending from the bottom of the coast to the Mananara River, a little north-west of the Antongil Bay, south to Vangiindran.
Also, can be found in the island reserve of Nasi Mangab in the bay of Antosil, a large population of black-and-white Ruffed lemurs are also found in the subspecies of the Varesea variega subicinta.
It is suspected that this population originated on the island in the 1930s. On the other hand, the Red ruffed Lemur has a very limited range on the Masawala Peninsula.
Historically, the confluence of the river Wohimara and the Antarmbalana may have been an area of hybridization between these two species, although no final results have indicated the current reproduction.
In general, the antennambalna river is black-and-white Ruffed lemur, red fragments emerge from the surrounding subspecies of Subicanta. Subspecies v. V. Varigata can be found further south and is the southernmost subspecies of the VVV editor. The overlap and intermediate forms of these two southern subspecies are known to exist, although this has not been confirmed.
Habitat during the rain
The two spots of rain that live on these animals are seasonal, with two primary zones: the hot, wet season (November to April) and the cool, dry season (from May to October). The primary habitat for both species, in any season, lies in the crowns of the tree, where they spend most of their time 15 and 25 meters (49 and 82 feet) above the ground.
Location There is no significant difference in tree use between species, regardless of the availability of resources in Tutu. From September to April there is more fruit available, so women prefer Liana at the crown of the tree. Both sexes prefer hot, lower, and main branches during the monsoon. The crown of the tree is mainly used from May to August when young leaves and flowers are abundant.
Ruffed lemurs either display feeding dominance or divide resources using different forest levels. They are dominant over the red-bellied lemurs, although the lower bamboo lemurs in the east can avoid them completely.
White-headed lemurs, on the other hand, prefer underage under 15 meters (49 feet) and lower canopies, while ruffed lemurs are essentially 15 meters (49 feet) in the upper canopy. There has even been a play between baby ruffed lemurs and white-headed lemurs.
Roofed lemurs feed on average 28% of the day, 53% of rest, and travel of 19%, although differences in rest and feeding duration are observed between males and females, wives are less rested and feed more. They are daily; Although peak activity occurs in the early morning and late afternoon or evening, rest usually occurs around midnight.
At rest, the ruffed lemurs is often predatory or upright. They are often seen lying in a branch at risk or in sunlight in a supine position stretching the limbs. When feeding, they will often hang upside down on their backs, a kind of suspensory behavior, which allows them to reach fruit and flowers.
Being excessively arboreal, they spend most of their time in a high canopy throughout the day. Ruffed lemurs spend most of their time between 15 and 20 meters (49 to 66 feet) above the forest floor, then go up to 20 to 25 meters (up to 66 feet up to 66 feet), and can be seen at least about 10 to 15 meters (49 Feet).
During the hot season, they will move to the lower camp to control their body temperature. During the winter season, chopped lemurs are least active and can devote 2% of their rest time to sunlight for the summer.
Long-term field research has shown that range size, group size, social order, and regional behavior vary widely and can be greatly influenced by food distribution and quality.
It is generally agreed that the ruffed lemur society is multi-male / multi-female with a fusion-fusion society, although some populations of black and white ruffed lemur have been reported to be exclusive. This social flexibility is suspected to improve survival skills despite a continuous feeding ecology.
Being the largest member of the family in leburidae, on average yields 1–3% of fruits, ruffed lemurs also drink nectar (8–22%), and mature leaves supplement their remaining meal with mature leaves ( 1%), flowers (3–6%) and some seed seeds Ruffed lemurs have also been reported to come to the ground for fungi and to display geophysics.
Most of their diet consists of relatively few common plant species, with some species providing more than 50% of the diet. For example, the fig species of the Ficus species account for 78% of the fruit consumed by red lemurs on the Masawala Peninsula. Although tree species and diets vary by place, the most common food plants found in the field include the following:
- Ravensara (family Lorisi)
- Eugenia / Syzygium
Fruit trees do not appear to be selected by the species but are demonstrated by the availability and accessibility of edible fruits. Despite the predominance of a few plant species in the Ruffed lemur diet, the remainder of their diet consists of 80 to 132 other species of 36 plant families.
The availability of food reflects the seasonal nature of the forests in which they live. During the hot season, fruits, flowers, and aromatic leaves are abundant, while in the cold, wet season the young leaves more flowers and flowers.
Nevertheless, diet varies slightly between diets, except that women will eat more high protein, low fiber items such as young leaves and flowers during pregnancy and breastfeeding to offset reproductive energy costs.
While nectar is only found scattered, flowers form a major food source after flowering. Tourist Palm Nectar (Ravenella madagascariensis) is a favorite among ruffed lemurs.
The social organization of ruffed lemurs varies greatly in both group organization and group composition, although no significant differences are seen between the two species. Ruffed lemurs are commonly described as a male group with a fission-fusion social structure, though they may vary seasonally and locally.
A study done on red-leaved lemurs on the Masoala Peninsula identified and defined the organization of three organizations: communities, core groups, and subgroups.
Communities are individuals that are regularly associated with one another but rarely with outside conspiracy. Although the entire multi-male / multi-female community lives in a separate home range, all individuals are never seen at the same time. Instead, individuals create social networks, which are known as core groups, that spread across communities.
Key groups are people who shared the same key territory in a community area throughout the year. Core groups usually consist of two reproductive wives, as well as reproductive males and subadults, whose size ranges from two individuals to nine.

Women in groups are cooperative but are often encountered in men. On the other hand, subgroups vary in daily size, composition, and duration and are composed of individuals belonging to the same core group or different core groups, depending on the associated trunk.
This is due to the regular, daily changes in these subgroups occurring throughout the year and the seasonal formations of the main groups in the region, demonstrating the fragmented-fusion nature of the rafted lemur social structure.
The fourth tier or organization was defined by another study done on Black and White Ruffed Lemurs in Nosy Manga: Approved; Affiliates were individuals with more stable social bonds and more frequent interactions, usually within a core group, but sometimes within core groups within a subgroup as well. Adult women were generally affiliated, where adult men rarely interacted with conspiracies, surviving a more desolate existence.
Past studies have reported other social entities in ruffed lemurs, including exclusive pair bonding. This may be due to the use of short-term, seasonal field studies rather than long-term studies that vary.
They take into account the effects on the ruffed lemur community. For example, during the winter, the rainy season, which coincides with the breeding season, the interaction between key groups within a community is significantly reduced.
During this period, the smaller subgroups are composed of a mature female, a mature male, and sometimes a descendant. This can be misinterpreted as an exclusive pair bond.
The behavior of the color can also show the variability of the season. During the heated, wet season, the female has grown alone or in groups of six. In the cool, dry season, small groups are stabilized to occupy short zones fore so, when the fruits are plentiful during the season, the subgroups become larger and the deficiency is seen as more solitary.
This suggests that the ecology of their feeding is not complex, although it is widely distributed, patchy, and sometimes tied to tropical fruits, but Ruffed lemurs can adapt to the social system instead.
In terms of domination, the social structure of rammed lemurs is not as clean as in other lemur societies, where female domination is the norm. Although it has been historically known that “men were subordinate to women”, especially the captive and free-ranging Lemur population, it shows that, because of inter-party change, the wild population cannot be identified as matriarchal.
Women generally have strong friendships with women, both within and outside their core areas, but are not allowed with people outside the community boundary except during the mating season.
Men, on the other hand, are more secluded, interact only with a few conspiratorial people, have weak social ties with other men, and rarely engage with others outside their core group.
Furthermore, field surveys suggest that only women play a role in the defense of communal home ranges. Men may have scent-marks and relatively silent, but otherwise, show little involvement during the conflict.
The size of the community range or region can vary from 16 to 197 hectares (0.16 to 2.0 km2; 0.062 to 0.76 square miles), but the size of the group can range from a single pair to 31 people. Population density is also noticeably variable.
The average daily travel distance of the Roofed Lemurs varies from 436 to 2,250 meters (1,430 to 7,382 feet), averaging 1,129 meters (3,704 feet) per day. Types of activities within the community range vary by gender and season. Males are usually in a key area throughout the year, where females are only bound to one key area during the winter wet season, then extend their range.
