Hog Badger
Hog badgers are three species of mustelid in the genus ''Arctonyx''. They represent one of the two genera in the subfamily Melinae, alongside the true badgers (genus '' Meles''). Taxonomy ''Arctonyx'' was formerly considered a monotypic genus containing one species, '' A. collaris'', but a 2008 study found it to comprise 3 distinct species, a finding later followed by the American Society of Mammalogists. Species Three species are known: Conservation The IUCN considers the greater hog badger (''A. collaris''), the northern hog badger (''A. albogularis'') and the Sumatran hog badger (''A. hoevenii'') as three separate species. The greater hog badger is listed as a Vulnerable species. The other two are listed as Least Concern A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. .. ...

Arctonyx Collaris
The greater hog badger (''Arctonyx collaris'') is a very large terrestrial mustelid native to Southeast Asia. It is listed as Vulnerable in the IUCN Red List of Threatened Species because the global population is thought to be declining due to high levels of poaching. Taxonomy It was formerly thought to be the only species in the genus ''Arctonyx'', displaying heavy variation throughout its wide range, leading it to be classified as having many subspecies. However, a 2008 study found that ''Arctonyx'' should be split into three species. The following subspecies were formerly recognized, but are now thought to be conspecific with little distinction between one another: * Greater hog badger ''A. c. collaris'' (Cuvier, 1825) – lives in the Eastern Himalayas;Ellerman, J.

American Society Of Mammalogists
The American Society of Mammalogists (ASM) was founded in 1919. Its primary purpose is to encourage the study of mammals, and professions studying them. There are over 4,500 members of this society, and they are primarily professional scientists who emphasize the importance of public policy and education. There are several ASM meetings held each year and the society manages several publications such as the ''Journal of Mammalogy'', ''Special Publications'', ''Mammalian Species ''Mammalian Species'' is a peer-reviewed scientific journal published by Oxford University Press on behalf of the American Society of Mammalogists. The journal publishes accounts of 12–35 mammal species yearly. The articles summarize the curr ...'', and ''Society Pamphlets''. The best known of these is the ''Journal of Mammalogy''. The ASM also maintains ''The Mammal Image Library'' which contains more than 1300 mammal slides. A president, vice president, recording secretary, secretary-treasurer, and ...

Vulnerable Species
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon is Vulnerable when it is not critically endangered or Endangered but is fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
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. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sumatran Hog Badger
The Sumatran hog badger (''Arctonyx hoevenii'') is a species of Mustelidae, mustelid Endemism, endemic to the island of Sumatra in Indonesia. Taxonomy It was formerly considered a subspecies of the greater hog badger (''A. collaris''), when it was considered the only species in the genus ''Arctonyx''. However, in 2008, a study proposed splitting ''A. collaris'' into 3 species, with one of these being ''A. hoevenii''. This finding was later followed by the American Society of Mammalogists. Description It is the smallest species of ''Arctonyx'', being about the size of a large Cat, housecat. It also has sparser fur and a much darker pelage than the other two species in the genus. Distribution The species is Endemism, endemic to the high-altitude regions of Sumatra, namely the Barisan Mountains, Barisan Range, which extends along the length of the island. Its range extends to the foothills, as low as 700 meters above sea level, up to the very highest point on the island; in 1 ...

Northern Hog Badger
The northern hog badger (''Arctonyx albogularis'') is a species of mustelid native to South and East Asia. Taxonomy It was formerly considered a subspecies of the greater hog badger (''A. collaris'') when ''A. collaris'' was considered the only species in '' Arctonyx'', but a 2008 study split the genus into 3 species, including ''A. albogularis''. Description The species is much smaller than the greater hog badger and has a more gracile skull. Elderly animals only have a moderately developed sagittal crest, in contrast to the two other species in the genus. It has a softer pelage with longer hairs than the other ''Arctonyx'', with thick underfur during the winter months. It has blackish forequarters, with the mid-back, tail, and hindquarters either being white or mixed with white. It is darker than the greater hog badger but lighter than the Sumatran hog badger. The species displays significant geographical variation, and some forms may represent distinct subspecies. Dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frédéric Cuvier
Georges-Frédéric Cuvier (28 June 1773 – 24 July 1838) was a French zoologist and paleontologist. He was the younger brother of noted naturalist and zoologist Georges Cuvier. Career Frederic was the head keeper of the menagerie at the Muséum d'Histoire Naturelle in Paris from 1804 to 1838. He named the red panda (''Ailurus fulgens'') in 1825. The chair of comparative physiology was created for him at the Muséum d'Histoire Naturelle in 1837. He was elected as a foreign member of the Royal Society in 1835. He is mentioned in Charles Darwin's ''On the Origin of Species'' (Chapter VII) as having worked on animal behaviour and instinct, especially the distinction between habit and instinct. He is also mentioned in Herman Melville's '' Moby-Dick'' (Chapter 32) as having written on the topic of whales. Evolution Cuvier has been described as the first scientist to use terms ''"héréditaire"'' (hereditary) in 1807 and "heredity” in 1812 in their now biological context. He used ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group ( taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopod ...

Meles (genus)
''Meles'' is a genus of badgers containing four living species known as Eurasian badgers, the Japanese badger (''Meles anakuma''), Asian badger (''Meles leucurus''), Caucasian badger (''Meles canescens'') and European badger (''Meles meles''). In an older categorization, they were seen as a single species with three subspecies (''Meles meles anakuma'', ''Meles meles leucurus'' and ''Meles meles meles''). There are also several extinct members of the genus. They are members of the subfamily Melinae of the weasel family, Mustelidae. Taxonomy The genus ''Meles'' was erected by French zoologist Mathurin Jacques Brisson in 1762 after Carl Linnaeus had described the Eurasian badger ''Meles meles'' in 1758. This animal had a very extensive range over most of temperate Europe and Asia and there has been much discussion as to whether it is a single or three distinct species. There are geographical differences between individuals from different parts of the range in skull structure, mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
