Qilian Bluetail
The Qilian bluetail (''Tarsiger albocoeruleus'') is a small passerine bird in the Old World flycatcher family Muscicapidae that is found in north-central China. It formerly considered as conspecific with the red-flanked bluetail (''Tarsiger cyanurus''). Taxonomy The Qilian bluetail was formally described in 1937 by the German ornithologist Wilhelm Meise as a subspecies of ''Tarsiger cyanurus'', the red-flanked bluetail. The epithet ''albocoeruleus'' combines the Latin ''albus'' meaning "white" with ''caeruleus'' meaning "blue". It was previously usually considered a synonym of ''T. cyanurus'', until accepted by Hadoram Shirihai and Lars Svensson in 2018, and it was proposed to be a full species in a molecular phylogenetic study published in 2022. It has now been recognised by the IOC World Bird List, and the ebird/Clements Checklist. It is distinctive in genetics and vocalisation, but only marginally different in morphology. The males have bluer fore-supercilium, and less white ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Meise
Wilhelm Meise (12 September 1901 in Essen - 24 August 2002 in Hamburg) was a German ornithology, ornithologist.Haffer, Jurgen (2003)''In memoriam'': Wilhelm Meise, 1901-2002 ''The Auk,'' 120(2): 540. (Apr 2003) He studied at the University of Berlin from 1924 to 1928, where he did his Ph.D. dissertation on the distribution of the carrion crow and the hooded crow, and hybridization between them under the supervision of Professor Erwin Stresemann, (1889–1972). He also analysed taxonomic and historic relationships between the house sparrow and the Spanish sparrow in particular the status of the "Italian sparrow". He was curator of vertebrates at the Museum of Natural History in Dresden from 1929 until World War II. Meise produced the first review of bird species new to science in 1934 at the eighth International Ornithological Congress (IOC), followed by an update at the ninth IOC in 1938. Meise, W.

Tarsiger
''Tarsiger'' is a genus of eight species of birds in the family Muscicapidae. They are small, mostly brightly coloured insectivorous birds native to Asia and (one species) northeastern Europe; four of the six species are confined to the Sino-Himalayan mountain system. The genus has sometimes been included within the related genus ''Luscinia'', but the species have been found to form a distinct monophyletic group. Taxonomy The genus ''Tarsiger'' was introduced in 1845 by the English naturalist Brian Houghton Hodgson with the golden bush robin as the type species. The genus name is from Ancient Greek ''tarsos'', "flat of the foot" and Latin ''gerere'', "to carry". The genus contains the following eight species: * White-browed bush robin (''Tarsiger indicus'') * Taiwan bush robin (''Tarsiger formosanus'') (split from ''T. indicus'') * Golden bush robin (''Tarsiger chrysaeus'') * Collared bush robin (''Tarsiger johnstoniae'') * Rufous-breasted bush robin (''Tarsiger hyperythrus ...

Supercilium
The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also known as an "eyebrow", it is distinct from the eyestripe, which is a line that runs across the lores, and continues behind the eye. Where a stripe is present only above the lores, and does not continue behind the eye, it is called a supraloral stripe or simply supraloral. On most species which display a supercilium, it is paler than the adjacent feather tracts. The colour, shape or other features of the supercilium can be useful in bird identification. For example, the supercilium of the dusky warbler, an Old World warbler The Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...

Bird Vocalisation
Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs (often simply ''birdsong'') are the bird sounds that are melodious to the human ear. In ornithology and birding, songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations). Definition The distinction between songs and calls is based upon complexity, length, and context. Songs are longer and more complex and are associated with territory and courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact. Other authorities such as Howell and Webb (1995) make the distinction based on function, so that short vocalizations, such as those of pigeons, and even non-vocal sounds, such as the drumming of woodpeckers and the "winnowing" of snipes' wings in display flight, are considered songs. Still others require song to have syllabic diversity and temporal regularity akin to the repe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinians, Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Phenotypic trait, Trait inheritance and Molecular genetics, molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the Cell (bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest. Latin Root (linguistics), roots appear frequently in the technical vocabulary used by fields such as theology, List of Latin and Greek words commonly used in systematic names, the sciences, List of medical roots, suffixes and prefixes, medicine, and List of Latin legal terms ...

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and one of the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al.

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), 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 as 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 name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
