Western Woolly Lemur
The western woolly lemur or western avahi (''Avahi occidentalis'') is a species of woolly lemur native to western Madagascar, where they live in dry deciduous forests. These nocturnal animals weigh . It is a folivorous species. The western woolly lemurs live in monogamous pairs together with their offspring. Ecology The Western woolly lemur mostly consumes leaves and buds that derive from around 20 different plants which have not matured and have high levels of sugars and proteins.The Primata. (2007) . Retrieved 2 April 2013.Arkive. (n.d."Western Woolly Lemur (Avahi occidentalis)". Retrieved 3 April 2013. The food is typically consumed within the time frame of two hours before dawn and two hours after dusk, in which the lemurs consume their food at the tops of trees ranging between 2 and 9 metres. During feeding time, lemurs typically settle on thinner branches unless the tree itself is too small to support the animal's weight. Most likely due to the lemur's folivorous diet, Wes ...

Ludwig Lorenz Von Liburnau
Ludwig Lorenz von Liburnau (26 August 1856 in Fiume – 9 December 1943 in St. Gilgen) was an Austrian zoologist. He was the son of naturalist Josef Roman Lorenz von Liburnau (1825–1911). In 1879 he obtained his PhD from the University of Vienna, receiving his habilitation in zoology in 1898. From 1880 to 1922 he was associated with the '' Naturhistorisches Museum'' in Vienna. In 1899 he was the first scientist to provide analysis of '' Hadropithecus stenognathus'' (an extinct species of lemur), a study based on a mandible discovered by fossil collector Franz Sikora at Andrahomana cave in southeastern Madagascar. At the time, Lorenz believed the specimen to be the mandible of an anthropoid primate species.

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woolly Lemur
The woolly lemurs, also known as avahis or woolly indris, are nine species of strepsirrhine primates in the genus ''Avahi''. Like all other lemurs, they live only on the island of Madagascar. The woolly lemurs are the smallest indriids with a body size of and a weight of . Their fur is short and woolly. The body can be grey-brown to reddish, with white on the back of the thighs, with a long, orange tail. The head is round with a short muzzle and ears hidden in the fur. Woolly lemurs can be found in humid and dry forests, spending most of their time in the leafy copse. Like many leafeaters, they need long naps to digest their food. Woolly lemurs live together in groups of two to five animals, often consisting of parents and several generations of their offspring. Like all indriids, the woolly lemurs are strictly herbivorous, eating predominantly leaves but also buds and, rarely, flowers. Males and females live in pairs. Groups consisting of the mating pair and their offspring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic. The island has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nocturnal
Nocturnality is a ethology, behavior in some non-human animals characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnality, diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing (sense), hearing, olfaction, smell, and specially adapted eyesight. Some animals, such as ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbaby, bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsier, tarsiers and some owl, owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folivore
In zoology, a folivore is a herbivore that specializes in eating leaves. Mature leaves contain a high proportion of hard-to-digest cellulose, less energy than other types of foods, and often toxic compounds.Jones, S., Martin, R., & Pilbeam, D. (1994) ''The Cambridge Encyclopedia of Human Evolution''. Cambridge: Cambridge University Press For this reason, folivorous animals tend to have long digestive tracts and slow metabolisms. Many enlist the help of symbiotic bacteria to release the nutrients in their diet. Additionally, as has been observed in folivorous primates, they exhibit a strong preference for immature leaves which tend to be easier to masticate, are higher in energy and protein, and lower in fibre and poisons than more mature fibrous leaves. Folivory and flight It has been observed that folivory is extremely rare among flying vertebrates. Morton (1978) attributed this to the fact that leaves are heavy, slow to digest, and contain little energy relative to other foo ...

Bombetoka Bay
Bombetoka Bay is a bay on the northwestern coast of Madagascar near the city of Mahajanga, where the Betsiboka River flows into the Mozambique Channel. Numerous islands and sandbars have formed in the estuary from the large amount of sediment carried in by the Betsiboka River and have been shaped by the flow of the river and the push and pull of tides. Along coastlines and on the islands, the vegetation is predominantly mangrove forests. In fact, Bombetoka Bay is home to some of Madagascar's largest remaining communities of mangroves, which provide shelter for diverse mollusk and crustacean communities, as well as habitat for sea turtles, birds, and dugongs. Along the northwest coast of Madagascar, mangroves and coral reefs partner to create dynamic, diverse coastal ecosystems. The mangrove forests capture river-borne sediment that would smother coastal reefs, while reefs buffer the mangroves from pounding surf. Near water, shrimp and rice farming are common, while coffee planta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woolly Lemurs
Wool is the textile fiber obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have some properties similar to animal wool. As an animal fiber, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibers, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but lack c ...

Mammals Described In 1898
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...
