There are two subspecies of A. laniger: Avahi laniger laniger is found in eastern Madagascar, and A. laniger occidentalis is found in northwestern Madagascar. The two subspecies are so similar that some researchers do not consider them to be distinct, though some behavioral differences have been noted.
(Flannery, 2000; Tattersall & Sussman, 1975)
As in other primates, it is likely that these animals use a variety of modalities of communication. Vocal communication has been reported. In addition, tactile communication, especially within the family unit, is expected. Visual communication, in the form of body postures and gestures probably also occurs.
Communication Channels: visual ; tactile ; acoustic
Perception Channels: visual ; tactile ; acoustic ; chemical
Woolly lemurs are small and secretive, protecting them from some predators. Their primary wild predators are Henst's goshawks, which find them while resting on exposed branches during the day.
(Flannery, 2000; Harcourt & Thornback, 1990; Wolfheim, 1983)
Known Predators:
Avahi laniger typically weighs between 600 and 1,300 g. Head and body length varies between 300 and 450 mm.
Woolly lemurs are typically grey-brown or reddish-brown in color, but color varies within the species. Th forearms, hands, legs, and feet are white and the tail is reddish-orange. The fur is thick and woolly (hence the common name), unlike other members of the family Indriidae, which have silky fur. Woolly lemurs have a spherical face which is covered in short hairs, their small ears are concealed within the woolly fur. Avahi laniger has large eyes and a short snout, and a characteristic white stripe that goes up the thigh. Sexes are similar, and it is nearly impossible to distinguish between males and females from a distance, though males have slightly larger molars and skulls. The lower incisors of woolly lemurs are modified into comb-like structure.
(Nowak, 1991; Parker, 1990)
Range mass: 600 to 1300 g.
Range length: 300 to 450 mm.
Sexual Dimorphism: male larger
Other Physical Features: endothermic ; bilateral symmetry
Little is known about the lifespan of A. laniger. They are reportedly unsuccessful in zoos, living no longer than three months in captivity outside of Madagascar. However, other members of the family Indriidae are reported to live over 23 years in captivity. It is reasonable to assume that A.laniger has a similar potential lifespan.
(Parker, 1990; Tattersol and Sussman, 1975; Nowak, 1991)
Typical lifespan
Status: captivity: few (low) months.
Avahi laniger is found in tropical regions. The population found in western Madagascar (A. laniger occidentalis) occupy dry seasonal forest where the elevation varies. In east Madagascar, A. laniger laniger occurs in a humid coastal forest at lower elevations.
(Flannery, 2000; Nowak, 1991; Parker, 1990)
Range elevation: 800 to 2000 m.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: rainforest ; scrub forest
Woolly lemurs are found only on the northwest and eastern sides of the island of Madagascar, off the southern coast of Africa.
(Harcourt and Thornback, 1990; Wolfheim, 1983)
Biogeographic Regions: ethiopian (Native )
Other Geographic Terms: island endemic
The diet of A. laniger is very similar to that of the closely related species Indri indri. The two species are able to live in the same area and share the same diet because they have different activity periods. Avahi laniger is active at night, whereas I. indri is a diurnal species. Although woolly lemurs have been known to eat flowers and fruits, their diet consists mainly of young leaves. They eat only the leaf blade, leaving the midrib and petiole behind.
One male A. laniger studied by Harcourt (1991) made some interesting feeding actions. The male often went to the end of a branch to pick leaves, then returned to the main trunk to eat them. He was also seen eating bits off leaves that remained attached to the tree.
(Cowlishaw & Dunbar, 2000; Harcourt, 1991)
Avahi laniger eats the leaves, buds, and twigs of: Harongana, Hafotra malady, Bararata, Hafidahy, Varongy, Voara, Herodrano, Fatsikahitra, Tavolarano petite feuille, Tavolomalady, Malambovany, Rotra madinika, Rahiaka, Mahanoram, Sary, Karambitoma, Rotra and Fohaninasity.
Plant Foods: leaves; fruit; flowers
Primary Diet: herbivore (Folivore )
Woolly lemurs are a species of great concern in conservation efforts, as are many other species in the Lemuridae and Indriidae families. This concern is mainly due to the considerable amount of habitat loss in Madagascar's tropical rainforests. Although this island known for extraordinary levels of endemic biodiversity and conservationists are working hard to protect lemur species, habitat loss and the hunting of lemurs for food continues at a rapid pace.
(Harcourt & Thornback, 1990; Nowak, 1991)
US Federal List: endangered
CITES: appendix i
IUCN Red List of Threatened Species: least concern
None known
Although A. laniger is an endangered species, it is still hunted for food by Malagasy people.
(Harcourt & Thornback, 1990)
Positive Impacts: food
Woolly lemurs act as a prey species for several predators, including humans. Through its folivory, A. laniger may influence plant composition in the forests where they live.
(Flannery, 2000)
Like many mammals on Madagascar, male and female A. laniger seem to mate for life. Couples stay together, raise their young, and live as a family.
(Parker, 1990)
Mating System: monogamous
Breeding occurs from March to May, followed by a gestation of approximately 135 days. Infant woolly lemurs are born during August and September and develop slowly. The baby stays with its mother and is weaned the following wet season. The time to weaning averages 6 months. Other members of the family Indriidae become independent after about 2 years of age.
(Nowak, 1991; Jolly, 1984)
Breeding interval: These interbirth interval of these animals is not known.
Breeding season: Breeding occurs from March to May.
Range number of offspring: 2 (high) .
Average number of offspring: 1.
Range gestation period: 120 to 150 days.
Range weaning age: 8 to 12 months.
Average weaning age: 6 months.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; viviparous
Although it is the mother that does most of the care for infant woolly lemurs, the father stays close by. Males have never been seen with a clinging infant.
Infants are dependent upon the mother until they are fully capable of feeding and traveling on their own. From birth to about 2 months, the infant is carried crosswise on the mothers' front side, and nurses 3 to 4 times a day in lengthy sessions. The mother situates herself in a comfortable position to settle down for an afternoon nap and feed her young. As the infant gets older, it moves from being carried on the front to the back and then begins to slowly venture away from the mother.
Feeding behavior begins incidental to play. Young begin playing with the food that the mother is eating, and casually gnaw on the twig or fruit. Thus they gradually learn which foods are safe and good to eat.
At this age, infants become more aware of the surrounding environment by grasping onto nearby branches. By 6 months, the now-weaned infant learns to leap from branch to branch following its mother. Infants do occasionally fall, sometimes up to 30 feet. In a few more months, they learn how to judge distances and make difficult leaps. At one year of age infant woolly lemurs become independent, although the mother is still close by. Even at 2 years of age, the relationship between mother and child is relatively close.

Der Östliche Wollmaki (Avahi laniger) ist eine Primatenart aus der Gruppe der Lemuren. Der Peyrieras-Wollmaki, der Südliche Wollmaki, der Ramanantsoavana-Wollmaki, der Betsileo-Wollmaki und der Moore-Wollmaki wurden kürzlich als eigenständige Arten von dieser Art abgetrennt.
Östliche Wollmakis erreichen eine Kopfrumpflänge von 25 bis 29 Zentimetern, der Schwanz wird 32 bis 37 Zentimeter lang und ihr Gewicht beträgt 0,9 bis 1,6 Kilogramm. Ihr Fell ist wie bei allen Wollmakis dicht und wollig, es ist an der Oberseite graubraun und an der Unterseite hellgrau gefärbt. Die Hinterbeine sind deutlich länger als die Vorderbeine, die Innenseite der Oberschenkel ist weißlich, der lange, buschige Schwanz ist rötlich braun gefärbt. Das Gesicht ist mit kurzen, braunen Haaren bedeckt und kontrastiert so mit der dichter behaarten Oberseite des Kopfes. Über den großen, runden Augen befinden sich kleine, weiße Flecken. Die Schnauze ist schwarz und kurz, die Ohren sind klein und teilweise im Fell verborgen.
Östliche Wollmakis kommen wie alle Lemuren auf Madagaskar vor, ihr Lebensraum sind die Regenwälder der Ostküste. Aufgrund der Abtrennung einiger Populationen als eigener Arten ist das genaue Verbreitungsgebiet nicht bekannt. Es erstreckt sich zumindest von der Region südlich der Masoala-Halbinsel bis zum Fluss Mangoro, ob es auch südlich des Mangoro Populationen dieser Art gibt, ist unklar. Sie kommen bis in 1600 Meter Seehöhe vor und erreichen ihre größte Bevölkerungsdichte in Sekundärwäldern.
Diese Primaten sind nachtaktive Baumbewohner. Tagsüber schlafen sie im dichten Blätterwerk verborgen, oft gegen einen Baumstamm gelehnt. In der Nacht gehen sie auf Nahrungssuche, dabei bewegen sie sich senkrecht kletternd und springend fort. Sie leben in Familiengruppen von zwei bis fünf Tieren, die sich aus einem monogamen Paar und dem gemeinsamen Nachwuchs zusammensetzen. Im Gegensatz zu vielen anderen nachtaktive Lemuren bleiben die Gruppenmitglieder auch während der Nahrungssuche zusammen. Familiengruppen bewohnen ein Revier von 1 bis 2 Hektar, das sie mit lauten Rufen gegenüber anderen Gruppen markieren.
Die Nahrung dieser Tiere besteht vorwiegend aus Blättern, in kleinem Ausmaß fressen sie auch Früchte und Blüten. Wie andere blätterfressende Säugetiere kompensieren sie den niedrigen Nährwert ihrer Nahrung mit langen Ruhepausen. Auch sind die nächtlichen Streifzüge sind mit 300 bis 500 Metern relativ kurz.
Die Paarung erfolgt im April oder Mai, im September oder Oktober bringt das Weibchen ein einzelnes Jungtier zur Welt. Dieses wird von der Mutter während ihrer Streifzüge mitgetragen und nicht an einer geschützten Stelle abgelegt. Nach rund sechs Monaten wird das Junge entwöhnt.
Aufgrund ihres relativ großen Verbreitungsgebietes sind Östliche Wollmakis weniger bedroht als andere Lemurenarten. Gebietsweise werden sie durch die Zerstörung ihres Lebensraums in Mitleidenschaft gezogen, insgesamt zählt die Art aber laut IUCN nicht zu den bedrohten Arten.

The eastern woolly lemur (Avahi laniger), also known as the eastern avahi or Gmelin's woolly lemur, is a species of woolly lemur native to eastern Madagascar, where it lives in the wet tropical rainforest at low elevations along the eastern coast of the island or they can also inhabit the northern tip of the island with other species.[4] The woolly lemur name refers to their thick, tightly curled hair, whereas their generic name avahi refers to their high-pitched defensive call. The eastern woolly lemur almost has an owl-look with its large eyes, small rounded head, and ears that are mostly hidden.[5] This nocturnal animal weighs 1.0–1.3 kg (2.2–2.9 lb) and reaches a length of 27–29 cm (11–11 in) with a tail of 33–37 cm (13–15 in). Its diet consists mainly of leaves and buds with fruits, flowers, and bark.
Eastern woolly lemurs live in monogamous pairs together with their offspring. The eastern woolly lemur's breeding season ranges from March to May with the baby lemurs being born around August to September.[6]
Other lemur species that live in the same rainforests as eastern woolly lemur are the diademed sifaka (Propithecus diadema) and the red-bellied lemur (Eulemur rubriventer). In southeastern rainforests, sympatric lemur species of A. meridionalis are the brown mouse lemur (Microcebus rufus), the greater dwarf lemur (Cheirogaleus major), the fat-tailed dwarf lemur (Cheirogaleus medius) and the collared brown lemur (Eulemur collaris) in Sainte Luce Forest, and the southern lesser bamboo lemur (Hapalemur meridionalis) in Mandena Forest.
According to one study, a male lemur rarely interacts with more than one other individual when sleeping, traveling or grooming. At night, he would spend about 40% of the time with his partner either grooming or resting.[7]
As of 2020, the eastern woolly Llemur continues to exist; however, based on a 2000 study, the entire lemur population might be endangered if the forests continues to "disappear at a disastrous rate".[8] This could be due to many reasons, for example deforestation and forest degradation.

Avahi laniger
L'Avahi laineux (Avahi laniger) est une espèce de primates appartenant à la famille des Indridae. Ce lémuriforme nocturne habite les forêts humides de l'est de Madagascar.
Il est également appelé avahi laineux oriental[1], pour le différencier de l'avahi laineux occidental, ou encore maki à bourre[2].
Il pèse de 1 à 1,3 kg et mesure de 27 à 29 cm, plus une queue de 33 à 37 cm.
Son régime alimentaire consiste principalement de feuilles et de bourgeons.
Les Avahis laineux sont monogames et vivent en couple solitaire, avec leurs petits.
Il est endémique au nord-est de Madagascar. Il vit dans la forêt tropicale humide de plaine et de montagne[3]

Il maki lanoso o avahi orientale (Avahi laniger (Gmelin, 1788)) è un lemure della famiglia degli Indriidi, endemico del Madagascar.[2]
Recentemente, la sottospecie Avahi laniger occidentalis è stata elevata al rango di specie a sé stante col nome di Avahi occidentalis.
Misura circa 30–45 cm, più altrettanti di coda, per un peso di circa 1 kg.
Il mantello, a differenza di quello degli altri indridi, è di aspetto lanoso anziché setoso: il colore è grigio-bruno, con variazioni individuali di tonalità. Gli avambracci, gli stinchi ed il pelo delle mani sono biancastri: una caratteristica striscia bianca corre su per le cosce, mentre la coda è di color rosso-arancio che tende ad inscurirsi nella parte distale.
La testa è tondeggiante, con piccole orecchie reniformi che vengono quasi del tutto celate dal pelo. Gli occhi sono grandi, da animale notturno (anche se la specie è diurna) ed il muso corto e tozzo.
Come in molte altre specie di lemuri, gli incisivi anteriori sono modificati a formare una sorta di pettine, utilizzato nelle operazioni di grooming.
A prima vista, i due sessi sono indistinguibili: un esame approfondito, tuttavia, rivela le maggiori dimensioni della testa e dei molari dei maschi in proporzione al corpo.
Si tratta di animali erbivori, diurni ed arboricoli: se costretti al suolo, saltellano lateralmente sulle zampe posteriori, come i sifaka, mentre sugli alberi sono animali lenti e cauti, anche se capaci di grandi salti.
A causa dello scarso valore nutritivo del loro cibo, non sono animali molto reattivi, anzi passano gran parte del loro tempo a sonnecchiare fra le chiome degli alberi, dove è una facile preda a causa della posizione assai esposta.
I maki lanosi sono animali sociali: vivono perlopiù in gruppi familiari, con una coppia dominante riproduttrice e vari cuccioli di differenti età, provenienti da varie cucciolate. Ogni gruppo occupa un territorio che si estende per circa 2 ettari, il che (assieme all'abitudine di marcare sporadicamente con le secrezioni delle ghiandole della gola le zone perifercihe del territorio) indica un certo grado di territorialità: tuttavia, non sono stati finora documentati episodi di violenza dovuta a sconfinamenti di territorio.
I vari componenti di un gruppo, od animali appartenenti a gruppi differenti, utilizzano principalmente la comunicazione visiva, assumendo determinate posizioni per comunicare; il grooming è utilizzato per creare o rinsaldare dei legami familiari, mentre raramente viene utilizzata la comunicazione tramite emissione di richiami.
L'alimentazione del maki lanoso consiste principalmente di foglie e germogli, anche se non di rado si osservano esemplari intenti a nutrirsi di foglie e frutti. L'animale mangia solo la parte esterna delle foglie, scartando il picciolo e la nervatura centrale, che spesso vengono lasciati attaccati alla pianta.
I maki lanosi sono animali rigorosamente monogami: la stagione riproduttiva va da marzo a maggio: la gestazione dura 4-5 mesi, al termine dei quali viene solitamente dato alla luce un unico cucciolo, anche se non sono infrequenti dei parti gemellari.
Il cucciolo resta attaccato a ventre ed in seguito (dopo il secondo mese) al dorso materno, mentre dopo il sesto mese è in grado di seguire la madre da solo, saltando di ramo in ramo: anche se il padre resta sempre nelle vicinanze, non sono mai stati avvistati maschi che trasportavano dei cuccioli.
Lo svezzamento completo viene raggiunto attorno all'ottavo mese di vita, ma il cucciolo tende a restare assieme ai genitori fino al compimento del secondo anno d'età.
Questi animali sono diffusi nella zona nord-orientale dell'isola, dove occupano la fascia costiera a basse altitudini, vivendo nella foresta pluviale.[1]
La IUCN Red List classifica Avahi laniger come specie vulnerabile.[1]
La specie è inserita nella Appendice I della Convention on International Trade of Endangered Species (CITES).[3]
È protetta all'interno del parco nazionale di Andasibe-Mantadia, del parco nazionale di Mananara, del parco nazionale di Marojejy, del parco nazionale di Zahamena, della riserva naturale integrale di Betampona, della riserva naturale integrale di Zahamena, della riserva speciale di Ambatovaky, della riserva speciale di Ambohitantely, della riserva speciale di Analamazaotra, della riserva speciale di Anjanaharibe Sud e della riserva speciale di Mangerivola.[1]

Multimedia w Wikimedia Commons Awahi wełnisty[3], lemur wełnisty[potrzebny przypis] (Avahi laniger) – gatunek ssaka z rodziny indrisowatych (Indridae) występujący w północno-zachodniej i wschodniej części Madagaskaru.
Długość ciała wynosi 30–45 cm, a masa ciała 600–1300 g. Futro ma barwę rudobrązową lub szarobrązową, odcień jest charakterystyczny dla danego osobnika. Ramiona i łapy są białe, ogon pomarańczowy. W odróżnieniu od innych przedstawicieli rodziny sierść tego lemura ma wełnistą strukturę, od której pochodzi jego nazwa. Twarz pokryta krótkimi włosami, uszy małe, schowane w sierści. Oczy duże, pysk krótki. Samce odróżnia od samic nieco większa czaszka i zęby trzonowe.
Lemury wełniste prowadzą nocny, nadrzewny tryb życia. Żyją w stadach rodzinnych na terytorium wynoszącym średnio 1–2 hektary (choć czasami dochodzi do czterech). Żywią się roślinami, głównie młodymi liśćmi, choć jedzą też kwiaty i owoce.
Lemury wełniste łączą się w pary na całe życie. Okres godowy trwa od marca do maja. Po 135 dniowej ciąży samica rodzi jedno, rzadziej dwa młode, które karmi następnie mlekiem przez pół roku. Młode osiągają dojrzałość w wieku 2 lat.
Przez pierwsze dwa miesiące życia młode podróżują uczepione brzucha matki. W trzecim miesiącu przechodzą na grzbiet, a także zaczynają poruszać się samodzielnie i oddalać od matki. W tym okresie także uczą się, które rośliny nadają się do spożycia. Po sześciu miesiącach lemury uczą się sprawnie poruszać po drzewach, skacząc z gałęzi na gałąź. Po roku mogą już żyć samodzielnie, ale nadal przebywają blisko matki i dopiero po kolejnym roku stają się całkowicie niezależne.
Hodowla lemurów wełnistych jest wyjątkowo trudna. Zwierzęta te nigdy nie rozmnażają się w niewoli, a wywiezione z Madagaskaru umierają już po kilku miesiącach. Zwierzęta te są czasami łapane i zjadane przez rodowitych mieszkańców Madagaskaru.
Lemur wełnisty nie jest bezpośrednio zagrożony wyginięciem. Największym zagrożeniem dla niego, jak dla większości fauny Madagaskaru, jest wycinka lasów i degradacja środowiska.

Avahi laniger[2][3][4] är en däggdjursart som först beskrevs av Gmelin 1788. Avahi laniger ingår i släktet ullmakier, och familjen indrier.[5][6] IUCN kategoriserar arten globalt som livskraftig.[1] Inga underarter finns listade i Catalogue of Life.[5]
Denna primat förekommer på nordöstra Madagaskar samt i ett avskild område på södra Madagaskar. Habitatet utgörs av tropiska skogar i låglandet och i bergstrakter.[1]
Individerna är aktiva på natten. På dagen vilar de gömda i växtligheten. En flock består av upp till fem individer och det antas att den består av ett vuxet föräldrapar och deras ungar. Reviret är en till två hektar stort och försvaras mot artfränder. I augusti eller september föder honan en unge. Avahi laniger äter blad och unga växtskott samt några frukter, blommor och bark.[1]
Avahi laniger blir 25 till 30 cm lång (huvud och bål) och har en 32 till 37 cm lång svans. På ovansidan är den ulliga pälsen gråbrun med röda skuggor och den yviga svansen har en tydlig rödbrun färg. Buken är huvudsakligen ljusgrå och på lårens utsida finns stora vita fläckar. Med sina stora ögon och små öron, som nästan är gömda i pälsen, liknar ansiktet en uggla.[7]
Vuxna honor kan ha en kull med en unge per år. Ungen klamrar sig i början fast vid moderns päls på framsidan och rider senare på moderns rygg.[7]
