Red Ruffed Lemur
The red ruffed lemur (''Varecia rubra'') is one of two species in the genus ''Varecia'', the ruffed lemurs; the other is the black-and-white ruffed lemur (''Varecia variegata''). Like all lemurs, it is native to Madagascar. It occurs only in the rainforests of Masoala, in the northeast of the island. It is one of the largest primates of Madagascar with a body length of 53 cm, a tail length of 60 cm and a weight of 3.3–3.6 kg. Its soft, thick fur is red and black in color and sports a buff or cream colored spot at the nape, but a few are known to have a white or pink patch on the back of the limbs or digits and a ring on the base of the tail in a similar color. Physical characteristics Ruffed lemurs are the largest members of the family Lemuridae, with this species being the larger of the two. They weigh . They are about long, with a tail. Females are slightly larger than males. They have slender bodies and long legs. Red ruffed lemurs have a narrow snout with ...

Varecia Rubra Im Detail
The ruffed lemurs of the genus ''Varecia'' are Strepsirrhini, strepsirrhine primates and the largest Extant taxon, extant lemurs within the family Lemuridae. Like all living lemurs, they are found only on the island of Madagascar. Formerly considered to be a monotypic genus, two species are now recognized: the black-and-white ruffed lemur, with its three subspecies, and the red ruffed lemur. Ruffed lemurs are Diurnality, diurnal and arboreal quadrupeds, often observed leaping through the upper Canopy (biology), canopy of the seasonal tropical rainforests in eastern Madagascar. They are also the most frugivore, frugivorous of the Malagasy lemurs, and they are very sensitive to habitat disturbance. Ruffed lemurs live in multi-male/multi-female groups and have a complex and flexible social structure, described as fission-fusion society, fission-fusion. They are highly vocal and have loud, raucous calls. Ruffed lemurs are seasonal breeders and highly unusual in their reproductive str ...

Étienne Geoffroy Saint-Hilaire
Étienne Geoffroy Saint-Hilaire (15 April 177219 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and expanded and defended Lamarck's evolutionary theories. Geoffroy's scientific views had a transcendental flavor (unlike Lamarck's materialistic views) and were similar to those of German morphologists like Lorenz Oken. He believed in the underlying unity of organismal design, and the possibility of the transmutation of species in time, amassing evidence for his claims through research in comparative anatomy, paleontology, and embryology. He is considered as a predecessor of the evo-devo evolutionary concept. Life and early career Geoffroy was born at Étampes (in present-day Essonne), and studied at the Collège de Navarre, in Paris, where he studied natural philosophy under M. J. Brisson. He then attended the lectures of Daubenton at the College de France and Fourcroy at the Jardin des Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weaning
Weaning is the process of gradually introducing an infant human or another mammal to what will be its adult diet while withdrawing the supply of its mother's milk. The process takes place only in mammals, as only mammals produce milk. The infant is considered to be fully weaned once it is no longer fed by any breast milk (or bottled substitute). Humans In some cultures, weaning progresses with the introduction of feeding the child food that has been prechewed by the parent along with continued breastfeeding, a practice known as premastication. The practice was important throughout human history in that it naturally gave a child a greatly improved protein source in addition to preventing iron deficiency. However, premasticated food from caregivers of lower socioeconomic status in areas of endemic diseases can result in the passing of the disease to the child. How and when to wean a human infant is controversial. The American Academy of Pediatrics recommends feeding a baby on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Madagascar
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...

Endemic Fauna Of Madagascar
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lemurs
Lemurs ( ) (from Latin ''lemures'' – ghosts or spirits) are wet-nosed primates of the superfamily Lemuroidea (), divided into 8 families and consisting of 15 genera and around 100 existing species. They are endemic to the island of Madagascar. Most existing lemurs are small, have a pointed snout, large eyes, and a long tail. They chiefly live in trees and are active at night. Lemurs share resemblance with other primates, but evolved independently from monkeys and apes. Due to Madagascar's highly seasonal climate, lemur evolution has produced a level of species diversity rivaling that of any other primate group. Until shortly after humans arrived on the island around 2,000 years ago, there were lemurs as large as a male gorilla. Most species have been discovered or promoted to full species status since the 1990s; however, lemur taxonomic classification is controversial and depends on which species concept is used. Lemurs range in weight from the mouse lemur to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breeding Program
A breeding program is the planned breeding of a group of animals or plants, usually involving at least several individuals and extending over several generations. There are a couple of breeding methods, such as artificial (which is man made) and natural (it occurs on its own). According to the Dutch State Secretary of Economic Affairs the delivery of young animals is important for the natural behavior of the mother, the herd and is desirable from a veterinary perspective. Breeding programs are commonly employed in several fields where humans wish to change the characteristics of their animals' offspring through careful selection of breeding partners: *Dog and cat fanciers may coordinate a breeding program to raise the probability of an animal's litter producing a championship-caliber animal. *Horse breeders try to produce fast racehorses through breeding programs. *Conservationists use breeding programs to try to help the recovery of endangered species by preserving the exis ...

Rosewood
Rosewood refers to any of a number of richly hued timbers, often brownish with darker veining, but found in many different hues. True rosewoods All genuine rosewoods belong to the genus ''Dalbergia''. The pre-eminent rosewood appreciated in the Western world is the wood of ''Dalbergia nigra''. It is best known as "Brazilian rosewood", but also as "Bahia rosewood". This wood has a strong, sweet smell, which persists for many years, explaining the name ''rosewood''. Another classic rosewood comes from ''Dalbergia latifolia'', known as (East) Indian rosewood or ''sonokeling'' (Indonesia). It is native to India and is also grown in plantations elsewhere in Pakistan (Chiniot). Madagascar rosewood (''Dalbergia maritima''), known as ''bois de rose'', is highly prized for its red color. It is overexploited in the wild, despite a 2010 moratorium on trade and illegal logging, which continues on a large scale. Throughout southeast Asia, ''Dalbergia oliveri'' is harvested for use in ...

Illegal Logging
Illegal logging is the harvest, transportation, purchase or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corrupt means to gain access to forests; extraction without permission, or from a protected area; the cutting down of protected species; or the extraction of timber in excess of agreed limits. Illegal logging is a driving force for a number of environmental issues such as deforestation, soil erosion and biodiversity loss which can drive larger scale environmental crisis such as climate change and other forms of environmental degradation. Illegality may also occur during transport, such as illegal processing and export (through fraudulent declaration to customs); the avoidance of taxes and other charges, and fraudulent certification. These acts are often referred to as "wood laundering". Illegal logging is driven by a number of economic forces, such as demand for raw materials, land grabbing and demand for pasture for ...

Fossa (animal)
The fossa (''Cryptoprocta ferox''; or ; ) is a slender, long-tailed, cat-like mammal that is endemic to Madagascar. It is a member of Eupleridae, the family of carnivorans, and closely related to the Malagasy civet. The fossa is the largest mammalian carnivore on Madagascar and has been compared to a small cougar, as it has convergently evolved many cat-like features. Adults have a head-body length of and weigh between , with the males larger than the females. It has semi-retractable claws (meaning it can extend but not retract its claws fully) and flexible ankles that allow it to climb up and down trees head-first, and also support jumping from tree to tree. A larger relative of the species, ''Cryptoprocta spelea'', probably became extinct before 1400. The species is widespread, although population densities are usually low. It is found solely in forested habitat, and actively hunts both by day and night. Over 50% of its diet consists of lemurs, the endemic primates found o ...
