White-spectacled Warbler
The white-spectacled warbler (''Phylloscopus intermedius'') is a species of leaf warbler in the family Phylloscopidae. It is found in Asia from the eastern Himalayas to south-eastern China and southern Vietnam. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It was formerly included in the Old World warbler family, Sylviidae. The white-spectacled warbler was described by the English entomologist and ornithologist Frederic Moore in 1854 and given the binomial name ''Abrornis affinis''. In 1898 the Irish ornithologist John David Digues La Touche described another bird to which he gave the binomial name ''Cryptolopha intermedia''. These two taxa were subsequently considered to belong to the same species and were placed in the genus ''Seicercus''. A molecular phylogenetic study published in 2018 found that neither ''Seicercus'' nor the closely related genus '' Phylloscopus'' were monophyletic. In the subsequen ...

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.

Birds Of Vietnam
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Samuel Tickell
Colonel Samuel Richard Tickell (19 August 1811 – 20 April 1875) was a British army officer, artist, linguist and ornithologist in India and Burma. Biography Tickell was born at Cuttack in India to Captain Samuel Tickell (of the 8th regiment of the Bengal Native Infantry) and Mary née Morris. His grandfather was Richard Tickell the English playwright and satirist. Lieutenant General Richard Tickell was a first cousin once removed. Samuel Tickell was educated in England with a training at Addiscombe from 1827 to 1829, returning at age nineteen to join the Bengal Native Infantry in 1829. He served in the 31st Bengal Native Infantry during the Kol campaign (1832–33). He was made commander of Brian Hodgson's military escort to Kathmandu from 1834. He returned to Bengal in 1843, and after his promotion to captain in 1847 he was moved to Arakan, lower Burma. He applied to serve as revenue surveyor in Bhagalpur in 1848 but found himself without experience and let his assistants work ...

Tickell's Leaf Warbler
Tickell's leaf warbler (''Phylloscopus affinis'') is a leaf warbler found in Asia in the countries of Bangladesh, Bhutan, China, India, Myanmar, Nepal, Pakistan and Thailand. The species has a yellowish underside and supercilium. Like other leaf warblers it feeds mostly on insects by gleaning and short sallies. An active bird, it prefers the canopy and low shrubbery and can be difficult to track as it moves actively from branch to branch, acrobatically exploring the underside of leaves and twigs. The clear yellowish undersides and lack of a wing bar can be used to tell it apart from similar species. It has slim dark legs with largely pale lower mandible and grayish wing panel. Taxonomy Tickell's leaf warbler was formally described in 1833 by the English ornithologist Samuel Tickell. He coined the binomial name ''Motacilla offinis'' where ''offinis'' is an error for ''affinis''. Tickell's leaf warbler is now one of around 80 species placed in the genus '' Phylloscopus'' that was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nominate 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] |
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] |
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 ...
