Ezo Flying Squirrel
The Ezo flying squirrel (''Pteromys volans orii'') or ''Ezo-momonga'' ( ja, エゾモモンガ) is a subspecies of the Siberian flying squirrel. It is endemic to Hokkaidō, Japan, part of the region once known as Ezo. In the legends of the local Ainu, the Ezo flying squirrel or '' A-kamui'' ( ain, アッ・カムイ) is a tutelary deity of children. Together with the Ezo chipmunk (''Eutamias sibiricus lineatus'') and (''Sciurus vulgaris orientis''), it is one of the three sciurids (members of the squirrel family (Sciuridae)) found on the island, to the north of Blakiston's Line, each having its own particular ecological niche. Taxonomy The Ezo flying squirrel was first described by Nagamichi Kuroda in 1921, as ''Sciuropterus russicus orii''. In 1940, John Reeves Ellerman elevated the Ezo flying squirrel to species rank and transferred it to the genus '' Pteromys'', the new combination being ''Pteromys orii''. In 1951, Ellerman and Morrison-Scott again treated the Ezo f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flying Squirrel
Flying squirrels (scientifically known as Pteromyini or Petauristini) are a tribe of 50 species of squirrels in the family Sciuridae. Despite their name, they are not in fact capable of full flight in the same way as birds or bats, but they are able to glide from one tree to another with the aid of a patagium, a furred parachute-like skin membrane that stretches from wrist to ankle. Their long tails also provide stability as they glide. Anatomically they are very similar to other squirrels with a number of adaptations to suit their lifestyle; their limb bones are longer and their hand bones, foot bones, and distal vertebrae are shorter. Flying squirrels are able to steer and exert control over their glide path with their limbs and tail. Molecular studies have shown that flying squirrels are monophyletic and originated some 18–20 million years ago. The genus Paracitellus is the earliest lineage to the flying squirrel dating back to the late Oligocene era. Most are nocturnal ...

Municipal Mergers And Dissolutions In Japan
can take place within one municipality or between multiple municipalities and are required to be based upon consensus. History There have been waves of merger activity between Japanese municipalities. The first merger, known as , had happened in the period from 1888 to 1889, when the modern municipal system was established. Before the mergers, existing municipalities were the direct successors of spontaneous hamlets called , or villages under the han system. The rump han system is still reflected in the postal system for rural areas as postal units called . The mergers slashed ‘natural settlements’ (shizen sh¯uraku) that existed at the time from 71,314 to 15,859 cities, towns and villages, justified at the time by the increased scale and relevance of the resulting respective autonomous governing bodies. The second peak, called , took place over the period from 1953 to 1956. It reduced the number of cities, towns and villages by over half, from 9,868 to 3,472 with purposes ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Orii Hyōjirō
(15 July 1883 – 27 April 1970) was a Japanese specimen collector of birds and mammals. At least a hundred new species and subspecies were described based on the type specimens he collected, a 2014 review putting the total, among taxa currently recognized, at 14 species and 41 subspecies of mammal, and 6 species and 68 subspecies of bird. The 7 mammal and 10 bird taxa named in honour of "Orii of the Orient" ( ja, 東洋のオリイ), as he came to be known, include the Ryūkyū shrew (''Crocidura orii'') and now-extinct Daitō varied tit (''Sittiparus varius orii''). Biography Born in Niigata Prefecture in 1883, Orii moved to Hakodate in 1899; in 1913 he would move again, from Hakodate to a house on the banks of the Bibi River where it meets Lake Utonai (now a Ramsar site), in what was then the village of Tomakomai. His career as a specimen collector took off in 1906, when he provided his services first to Malcolm Playfair Anderson, then to Alan Owston. In 1906/7, ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smithsonian Institution
The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums and education and research centers, the largest such complex in the world, created by the U.S. government "for the increase and diffusion of knowledge". Founded on August 10, 1846, it operates as a trust instrumentality and is not formally a part of any of the three branches of the federal government. The institution is named after its founding donor, British scientist James Smithson. It was originally organized as the United States National Museum, but that name ceased to exist administratively in 1967. Called "the nation's attic" for its eclectic holdings of 154 million items, the institution's 19 museums, 21 libraries, nine research centers, and zoo include historical and architectural landmarks, mostly located in the District of Columbia. Additional facilities are located in Maryland, New York, and Virginia. More than 200 institutions and museums in 45 states,States without Smithsonian ...

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the large ''Diplodocus'' cast that domina ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...
