Eupleres Major
The western falanouc (''Eupleres major'') is a rare mongoose-like mammal endemic to Madagascar. Until recently, the eastern falanouc (''Eupleres goudotii'') was the only recognized species in the genus ''Eupleres''. In 2010, Goodman and Helgen provided morphological evidence showing the two falanoucs are each a separate species and are found in separate geographical locations. ''E. major'' is larger and browner compared to ''E. goudotii'' and has a diet consisting mainly of invertebrates such as worms, snails, and slugs. Knowledge of the western falanouc's ecology is limited, but its range is believed to be limited to dry deciduous forest, flooded palm savanna, and wetlands. ''E. major'' is known to occur in Ankarafantsika National Park and is believed to also be found in or near other local national parks and reserves. The main predators of the western falanouc are feral dogs and humans. ''E. major'' is currently listed as ''endangered'' on the IUCN Red List of Endangered Species ...

Louis Lavauden
Louis Lavauden (19 June 1881, in Grenoble – 1 September 1935, in Anjou, Isère) was a French zoologist and forester. He was a student at the Institut agronomique et de l'Ecole forestière in Nancy, afterwards conducting zoological studies of the province Dauphiné. In 1912–13 he performed research of the fauna in Algeria and Tunisia, and following World War I, returned to Tunisia as a forester. In 1925 he took part in one of the first motorized crossings of the Sahara (from Tunis to Cotonou via Lake Chad). From 1928 he was stationed in Madagascar, where he collected zoological specimens that included a number of lemur species. Lavauden is credited with providing descriptions for several new mammal and avian species/subspecies. Many of his collections are housed at the natural history museum in Grenoble :fr:Muséum d'histoire naturelle de Grenoble. He was, from 1929, on the editorial committee of ''Alauda, Revue internationale d'Ornithologie'' :fr:Alauda, Revue intern ...

CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working lang ...

Ankarana Reserve
Ankarana Special Reserve in northern Madagascar was created in 1956. It is a small, partially vegetated plateau composed of 150-million-year-old middle Jurassic limestone. With an average annual rainfall of about , the underlying rocks have been eroded to produce caves and feed subterranean rivers—a karst topography. The rugged relief and the dense vegetation have helped protect the region from human intrusion. The southern entrance of the park is in Mahamasina on the Route nationale 6 (Madagascar), Route nationale 6 some 108 km south-west of Antsiranana and north-east of Ambilobe. Geology The plateau slopes gently to the east, but on the west it ends abruptly in the "Wall of Ankarana", a sheer cliff that extends north to south, and rises up to . To the south, the limestone mass breaks up into separate spires known as ''tower karst''. In the center of the plateau, seismic activity and eons of rainfall have eroded the limestone, forming deep gorges and ribbons of flowsto ...

Generation Time
In population biology and demography, generation time is the average time between two consecutive generations in the lineages of a population. In human populations, generation time typically ranges from 22 to 33 years. Historians sometimes use this to date events, by converting generations into years to obtain rough estimates of time. Definitions and corresponding formulas The existing definitions of generation time fall into two categories: those that treat generation time as a renewal time of the population, and those that focus on the distance between individuals of one generation and the next. Below are the three most commonly used definitions: The time it takes for the population to grow by a factor of its net reproductive rate The net reproductive rate \textstyle R_0 is the number of offspring an individual is expected to produce during its lifetime (a net reproductive rate of 1 means that the population is at its demographic equilibrium). This definition envisions the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources.

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Malagasy Carnivoran
Eupleridae is a family of carnivorans endemic to Madagascar and comprising 10 known living species in seven genera, commonly known as euplerids, Malagasy mongooses or Malagasy carnivorans. The best known species is the fossa (''Cryptoprocta ferox''), in the subfamily Euplerinae. All species of Euplerinae were formerly classified as viverrids, while all species in the subfamily Galidiinae were classified as herpestids. Recent molecular studies indicate that the 10 living species of Madagascar carnivorans evolved from one ancestor that is thought to have rafted over from mainland Africa 18–24 million years ago. This makes Malagasy carnivorans a clade. They are closely allied with the true herpestid mongooses, their closest living relatives. The fossa and the Malagasy civet (''Fossa fossana'') are each evolutionarily quite distinct from each other and from the rest of the clade. All Eupleridae are considered threatened species due to habitat destruction, as well ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
