Madagascan Rousette
The Madagascan rousette (''Rousettus madagascariensis'') or Madagascar rousette, is a species of megabat in the family Pteropodidae endemic to Madagascar. Its natural habitat is subtropical or tropical dry forests. Description The Madagascan rousette is a small fruit bat, the smallest of the three fruit bats endemic to Madagascar. The upper part of their bodies have a greyish fur while the underparts have a paler grey tinge. Like many other fruit bats, Madagascan rousettes have very dog-like faces with long, pointed snouts, large, wide eyes and largely separated ears. Like some other members of the genus ''Rousettus'', these bats reside within cave roosts, suggesting the use of echolocation. These bats are a part of a larger group of fruit bats within ''Rousettus'' which consists of 10 different species. The Madagascan rousette primarily resides on western islands of the Indian Ocean. Ecology Habitat The habitat of the Madagascan rousette is generally found to be associate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guillaume Grandidier
Guillaume Grandidier (1 July 1873 – 13 September 1957) was a French geographer, ethnologist, zoologist who studied the island of Madagascar. He was the son of the wealthy industrialist Alfred Grandidier also a zoologist and expert on Madagascar. Guillaume Grandidier was Secretary of the Geographical Society of Paris and a prolific author. The ''Atlas des Colonies Françaises, Protectorats et Territoires sous Mandat de la France'', simply known as the Atlas Grandidier, was published under his direction in 1934. Among his other works was the monumental ''Madagascar L'Histoire politique, physique et naturelle de Madagascar''. This work was undertaken in cooperation with his father and others such as Alphonse Milne-Edwards and Leon Vaillant. This work ran to 40 volumes. '' Liopholidophis grandidieri'', a species of snake endemic to Madagascar, was named in his honor by French herpetologist François Mocquard. Mocquard F. 1904.

Megabat
Megabats constitute the family Pteropodidae of the order Chiroptera (bats). They are also called fruit bats, Old World fruit bats, or—especially the genera ''Acerodon'' and ''Pteropus''—flying foxes. They are the only member of the superfamily Pteropodoidea, which is one of two superfamilies in the suborder Yinpterochiroptera. Internal divisions of Pteropodidae have varied since subfamilies were first proposed in 1917. From three subfamilies in the 1917 classification, six are now recognized, along with various tribes. As of 2018, 197 species of megabat had been described. The leading theory of the evolution of megabats has been determined primarily by genetic data, as the fossil record for this family is the most fragmented of all bats. They likely evolved in Australasia, with the common ancestor of all living pteropodids existing approximately 31 million years ago. Many of their lineages probably originated in Melanesia, then dispersed over time to mainland Asia, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Hendra Virus
Hendra virus (HeV), scientific name ''Hendra henipavirus'', is a bat-borne virus that is associated with a highly fatal infection in horses and humans. Numerous disease outbreaks in Australia among horses have been caused by Hendra virus. The Hendra virus belongs to the genus ''Henipavirus'', which also contains the Nipah virus, which has also caused disease outbreaks. Pathology Flying foxes experimentally infected with the Hendra virus develop a viraemia and shed the virus in their urine, faeces and saliva for approximately one week. There is no other indication of an illness in them. Symptoms of Hendra virus infection of humans may be respiratory, including hemorrhage and edema of the lungs, or in some cases viral meningitis. In horses, infection usually causes one or more of pulmonary oedema, congestion and neurological signs. Ephrin B2 has been identified as the main receptor for the henipaviruses. Transmission Flying foxes have been identified as the reservoir host of Hend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henipavirus
''Henipavirus'' is a genus of negative-strand RNA viruses in the family ''Paramyxoviridae'', order ''Mononegavirales'' containing six established species, and numerous others still under study. Henipaviruses are naturally harboured by several species of small mammals, notably Pteropus, pteropid fruit bats (flying foxes), microbats of several species, and shrews. Henipaviruses are characterised by long genomes and a wide host range. Their recent emergence as zoonosis, zoonotic pathogens capable of causing illness and death in domestic animals and humans is a cause of concern. In 2009, RNA sequences of three novel viruses in phylogenetic relationship to known henipaviruses were detected in African straw-colored fruit bats (''Eidolon helvum'') in Ghana. The finding of these novel henipaviruses outside Australia and Asia indicates that the region of potential endemicity of henipaviruses may be worldwide. These African henipaviruses are slowly being characterised. ''Nipah virus, Nipa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tioman Virus
Tioman Island ( ms, Pulau Tioman) is a mukim and an island in Rompin District, Pahang, Malaysia. It is located off the east coast of the state, and is some long and wide. It has seven villages, the largest and most populous being Kampung Tekek on the central western coast. The densely forested island is sparsely inhabited, and is surrounded by numerous coral reefs, making it a popular scuba diving, snorkelling, and surfing spot. There are many resorts and chalets for tourists around the island, which has duty-free status. In the 1970s, ''TIME Magazine'' selected Tioman as one of the world's most beautiful islands. The island is part of Pahang territory. However, it is geographically closer to mainland Johor than to mainland Pahang and is accessed via ferry service from the Johorean coastal town of Mersing. Within Tioman Island there are seven kampungs: Salang, Air Batang, Tekek, Paya, Genting, Mukut and Juara. The telephone numbers in Tioman start with 09-413, 09-41 ...

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 ...
