Ryukyu Robin
The Ryukyu robin (''Larvivora komadori'') is a bird endemic to the Ryūkyū Islands, of Japan. The Okinawa robin (''Larvivora namiyei'') previously was considered a subspecies. The specific name ''komadori'' is, somewhat confusingly, the common name of its relative the Japanese robin in Japanese. The Ryukyu robin, together with the Japanese robin and the European robin, was previously placed in the genus ''Erithacus'' . A 2006 molecular phylogenetic study found that the two east Asian species were more similar to the Siberian blue robin, at the time in ''Luscinia'', than to the European robin. In 2010 a large study confirmed this result and also found that ''Luscinia'' was non-monophyletic. The genus ''Larvivora'' was therefore resurrected to accommodate a clade containing the Japanese robin, the Ryukyu robin, the Siberian blue robin and several other species that had previously been placed in ''Luscinia''.

Erithacus
''Erithacus'' (Greek: "robin" (erithacos)) is a genus of passerine bird that contains a single extant species, the European robin ''(Erithacus rubecula)''. The Japanese robin and Ryukyu robin were also placed in this genus (as ''Erithacus akahige'' and ''E. komadori''), but were moved to the genus ''Larvivora'' in 2006.

Endemic Fauna Of The Ryukyu Islands
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] |
Endemic Birds Of Japan
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. For an overview of this subject see Endemism in birds. Patterns of endemism Japan has no endemic families. It has one endemic genus: '' Apalopteron'', which contains the Bonin white-eye. The extinct Bonin grosbeak was formerly considered the only member of the genus '' Chaunoproctus'', but taxonomic analysis supports it as being a basal member of the rosefinch genus ''Carpodacus''. Endemic Bird Areas Birdlife International has defined the following Endemic Bird Areas (EBAs) in Japan: * Izu Islands * Ogasawara Islands * Nansei Shoto The following have been designated as secondary areas: * Central Honshu lowland forests * Central Honshu montane forests * Iwo Islands * Other islands List of species The following is a list of bird species endemic to Japan: Resident endemics Breeding endemics References {{Endemism in birds Japan Japan ( ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Larvivora
''Larvivora'' is a genus of small passerine birds belonging to the Old World flycatcher family Muscicapidae that occur in central and eastern Asia. The seven species in this genus were all previously placed in other genera. A large molecular phylogenetic study published on 2010 found that the genera ''Luscinia'' and ''Erithacus'' as defined by Edward C. Dickinson in 2003 were not monophyletic. The genus ''Larvivora'' with the type species ''Larvivora cyane'' was reinstated to accommodate a well-defined clade. Although the rufous-headed robin was not included in the phylogenetic study, it was moved to the resurrected genus as it is similar in structure, song and behaviour to the Indian blue robin and the Siberian blue robin. The genus ''Larvivora'' had been introduced by the British naturalist Brian Houghton Hodgson in 1837. The word ''Larvivora'' comes from the new Latin ''larva'' meaning caterpillar and ''-vorus'' meaning eating (''vorace'' to devour). The genus includes th ...

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Luscinia
''Luscinia '' is a genus of smallish passerine birds, containing the nightingales and relatives. Formerly classed as members of the thrush family Turdidae, they are now considered to be Old World flycatchers (Muscicapidae) of the chat subfamily (Saxicolinae). The chats are a lineage of Old World flycatchers that has evolved convergently to thrushes. Taxonomy and systematics The word ''Luscinia'' was used for nightingales and similar birds in Classical Latin (e.g. in the AD 70s ''Naturalis Historia'' by Pliny the Elder), if not earlier. Etymologically, it might be derived from ''luscus'' (Latin for "half-blind", "half-understood" etc.) or ''clueō'' (Latin for "to be well-known") + (probably) Latin ''canō'' "to sing". Hence, it could be translated as "little-seen s in the twilightsongster" or "famous songster". The genus ''Luscinia'' was introduced by the English naturalist Thomas Forster in 1817. The type species is the common nightingale (''Luscinia megarhynchos''). Delimi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siberian Blue Robin
The Siberian blue robin (''Larvivora cyane'') is a small passerine bird that was formerly classified as a member of the thrush family, Turdidae, but is now more generally considered to belong to the Old World flycatcher family, Muscicapidae. It and similar small European species are often called chats. Recent research suggests that this species and some other East Asian members of ''Luscinia'' should be classified in a new genus, together with the Japanese and Ryūkyū robins. The genus name ''Larvivora'' comes from the new Latin ''larva'' meaning caterpillar and ''-vorus'' meaning eating (''vorace'' to devour), and ''cyane'' is Latin for "dark-blue". This bird is a migratory insectivorous species breeding in the eastern Palearctic from Siberia and northern Mongolia, northeastern China, Korea and across to Japan. It winters in southern and south-eastern Asia and Indonesia. The breeding habitat is coniferous forest with dense undergrowth, often beside rivers or at woodland edg ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Coenraad Jacob Temminck
Coenraad Jacob Temminck (; 31 March 1778 – 30 January 1858) was a Dutch people, Dutch Aristocracy (class), aristocrat, Zoology, zoologist and museum director. Biography Coenraad Jacob Temminck was born on 31 March 1778 in Amsterdam in the Dutch Republic. From his father, Jacob Temminck, who was treasurer of the Dutch East India Company with links to numerous travellers and collectors, he inherited a large collection of bird specimens. His father was a good friend of Francois Levaillant who also guided Coenraad. Temminck's ''Manuel d'ornithologie, ou Tableau systématique des oiseaux qui se trouvent en Europe'' (1815) was the standard work on European birds for many years. He was also the author of ''Histoire naturelle générale des Pigeons et des Gallinacées'' (1813–1817), ''Nouveau Recueil de Planches coloriées d'Oiseaux'' (1820–1839), and contributed to the mammalian sections of Philipp Franz von Siebold's ''Fauna japonica'' (1844–1850).
