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 taxon, 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 nocturnality, nocturnal. They navigate with keen eyesight, as they cannot Animal echolocation, echolocate. They have R/K selection theory#K-selection, 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 Overexploitation, overhunting, culling, and natural disasters. Six flying fox species have been ...

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] |
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 "allege ... [...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 ...

Yinpterochiroptera
The Yinpterochiroptera (or Pteropodiformes) is a suborder of the Chiroptera, which includes taxa formerly known as megabats and five of the microbat families: Rhinopomatidae, Rhinolophidae, Hipposideridae, Craseonycteridae, and Megadermatidae. This suborder is primarily based on molecular genetics data. This proposal challenged the traditional view that megabats and microbats form monophyletic groups of bats. Further studies are being conducted, using both molecular and morphological cladistic methodology, to assess its merit. The term Yinpterochiroptera is constructed from the words Pteropodidae (the family of megabats) and Yinochiroptera (a term proposed in 1984 by Karl F. Koopman to refer to certain families of microbats). Recent studies using transcriptome data have found strong support for the Yinpterochiroptera-Yangochiroptera classification system. Researchers have created a relaxed molecular clock that estimates the divergence between Yinpterochiroptera and Yangochirop ...

Australian Bat Lyssavirus
''Australian bat lyssavirus'' (''ABLV''), originally named ''Pteropid lyssavirus'' (''PLV''), is a zoonotic virus closely related to the rabies virus. It was first identified in a 5-month-old juvenile black flying fox (''Pteropus alecto'') collected near Ballina in northern New South Wales, Australia, in January 1995 during a national surveillance program for the recently identified Hendra virus. ABLV is the seventh member of the genus ''Lyssavirus'' (which includes ''Rabies virus'') and the only ''Lyssavirus'' member present in Australia. Prevalence ABLV is distributed throughout Australia in a variety of bat species which are believed to be the primary reservoir for the virus. Surveillance initiatives also confirmed the presence of lyssavirus in both Pteropid (Gould ''et al.''., 1998) and insectivorous bats (Gould ''et al.''., 2002; Hooper ''et al.''., 1997), and later, human infections were reported following encounters with both fruit and insectivorous bats (Allworth ''et ...

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] |

Natural Reservoir
In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival. A reservoir is usually a living host of a certain species, such as an animal or a plant, inside of which a pathogen survives, often (though not always) without causing disease for the reservoir itself. By some definitions a reservoir may also be an environment external to an organism, such as a volume of contaminated air or water. Because of the enormous variety of infectious microorganisms capable of causing disease, precise definitions for what constitutes a natural reservoir are numerous, various, and often conflicting. The reservoir concept applies only for pathogens capable of infecting more than one host population and only with respect to a defined target popula ...

Rabies
Rabies is a viral disease that causes encephalitis in humans and other mammals. Early symptoms can include fever and tingling at the site of exposure. These symptoms are followed by one or more of the following symptoms: nausea, vomiting, violent movements, uncontrolled excitement, fear of water, an inability to move parts of the body, confusion, and loss of consciousness. Once symptoms appear, the result is virtually always death, regardless of treatment. The time period between contracting the disease and the start of symptoms is usually one to three months but can vary from less than one week to more than one year. The time depends on the distance the virus must travel along peripheral nerves to reach the central nervous system. Rabies is caused by lyssaviruses, including the rabies virus and Australian bat lyssavirus. It is spread when an infected animal bites or scratches a human or other animals. Saliva from an infected animal can also transmit rabies if the saliva come ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 fu ... [...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 declared ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
