Pteropus
''Pteropus'' (suborder Yinpterochiroptera) is a genus of megabats which are among the largest bats in the world. They are commonly known as fruit bats or flying foxes, among other colloquial names. They live in South Asia, Southeast Asia, Australia, East Africa, and some oceanic islands in the Indian and Pacific Oceans. There are at least 60 extant species in the genus. Flying foxes eat fruit and other plant matter, and occasionally consume insects as well. They locate resources with their keen sense of smell. Most, but not all, are nocturnal. They navigate with keen eyesight, as they cannot echolocate. They have long life spans and low reproductive outputs, with females of most species producing only one offspring per year. Their slow life history makes their populations vulnerable to threats such as overhunting, culling, and natural disasters. Six flying fox species have been made extinct in modern times by overhunting. Flying foxes are often persecuted for their real or ...

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mauritian Flying Fox
The Mauritian flying fox (''Pteropus niger''), also known as Greater Mascarene flying fox or Mauritius fruit bat is a large megabat species endemic to Mauritius and La Réunion. Description The Mauritian flying fox can reach a wingspan of 80 cm (31 in), making it the largest endemic mammal on Mauritius. Its fur is golden. It has small ears, thick hair on the tibiae, dorsal coloration of glossy, blackish brown mantle, tinged with rufous, which extends posteriorly into a dark brown median spinal tract, flanked by buff lateral patches. It is a medium-sized species; the adult forearm length averages 152 mm, with no difference between males and females. Mostly nocturnal, although some are occasionally seen during the day, they normally roost by sunrise. These fruit bats range in size from 40-800 g and occur from sea level to 1500 m above. Origin The split of ''Pteropus'' species from their megabat relatives was between 28.37 and 34.63 million years ago. Within the gen ...

Large Flying Fox
The large flying fox (''Pteropus vampyrus'', formerly ''Pteropus giganteus''), also known as the greater flying fox, Malayan flying fox, Malaysian flying fox, large fruit bat, kalang, or kalong, is a southeast Asian species of megabat in the family Pteropodidae. Despite its scientific name, it feeds exclusively on fruits, nectar, and flowers, like the other flying foxes of the genus '' Pteropus''. It is noted for being one of the largest bats. As with nearly all other Old World fruit bats, it lacks the ability to echolocate but compensates for it with well-developed eyesight. Taxonomy The large flying fox was one of the many mammal species originally described by Carl Linnaeus in the landmark 1758 10th edition of his '' Systema Naturae'', receiving the name ''Vespertilio vampyrus''. The holotype was collected on Java. Its species name "''vampyrus''" is derived from Slavic "wampir" meaning "blood-sucking ghost or demon: vampire". This name was chosen in reference to its ...

Robert Kerr (writer)
Dr Robert Kerr FRSE FAS FRCSE (20 October 1757 – 11 October 1813) was a Scottish surgeon, writer on scientific and other subjects, and translator. Life Kerr was born in 1757 in Bughtridge, Roxburghshire, the son of James Kerr, a jeweller, who served as MP for Edinburgh 1747–1754, and his wife Elizabeth. He was sent to the High School in Edinburgh. He studied medicine at the University of Edinburgh and practised at the Edinburgh Foundling Hospital as a surgeon. He was elected a Fellow of the Royal Society of Edinburgh in 1788. His proposers were Alexander Fraser Tytler, James Russell and Andrew Dalzell. At this time he lived at Foresters Wynd off the Royal Mile in Edinburgh. He translated several scientific works into English, such as Antoine Lavoisier's work of 1789, ''Traité Élémentaire de Chimie'', published under the title ''Elements of Chemistry in a New Systematic Order containing All the Modern Discoveries'', in 1790.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

International Commission On Zoological Nomenclature
The International Commission on Zoological Nomenclature (ICZN) is an organization dedicated to "achieving stability and sense in the scientific naming of animals". Founded in 1895, it currently comprises 26 commissioners from 20 countries. Organization The ICZN is governed by the "Constitution of the ICZN", which is usually published together with the ICZN Code. Members are elected by the Section of Zoological Nomenclature, established by the International Union of Biological Sciences (IUBS). The regular term of service of a member of the Commission is six years. Members can be re-elected up to a total of three full six-year terms in a row. After 18 continuous years of elected service, a break of at least three years is prescribed before the member can stand again for election. Activities Since 2014, the work of the Commission is supported by a small secretariat based at the National University of Singapore, in Singapore. Previously, the secretariat was based in London and fun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Principle Of Priority
270px, '' valid name. Priority is a fundamental principle of modern botanical nomenclature and zoological nomenclature. Essentially, it is the principle of recognising the first valid application of a name to a plant or animal. There are two aspects to this: # The first formal scientific name given to a plant or animal taxon shall be the name that is to be used, called the valid name in zoology and correct name in botany (principle of synonymy). # Once a name has been used, no subsequent publication of that name for another taxon shall be valid (zoology) or validly published (botany) (principle of homonymy). Note that nomenclature for botany and zoology is independent, and the rules of priority regarding homonyms operate within each discipline but not between them. There are formal provisions for making exceptions to the principle of priority under each of the Codes. If an archaic or obscure prior name is discovered for an established taxon, the current name can be decla ... [...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 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 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'' and '' Hendra henipaviruses' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
