Blue Tit
The Eurasian blue tit (''Cyanistes caeruleus'') is a small passerine bird in the tit family, Paridae. It is easily recognisable by its blue and yellow plumage and small size. Eurasian blue tits, usually resident and non-migratory birds, are widespread and a common resident breeder throughout temperate and subarctic Europe and the western Palearctic in deciduous or mixed woodlands with a high proportion of oak. They usually nest in tree holes, although they easily adapt to nest boxes where necessary. Their main rival for nests and in the search for food is the larger and more common great tit. The Eurasian blue tit prefers insects and spiders for its diet. Outside the breeding season, they also eat seeds and other vegetable-based foods. The birds are famed for their acrobatic skills, as they can hold on to the outermost branches of trees and shrubs and hang upside down when looking for food. Taxonomy The Eurasian blue tit was described by Carl Linnaeus in 1758 in the 10th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikolai Zarudny
Nikolai Alekseyvich Zarudny (russian: Николай Алексеевич Зарудный; rus, Николай Алексеевич Зарудный, r=Nikolay Alekseevich Zarudny. His name has been transliterated a number of other ways; especially with ''Sarudny'' or ''Sarudney'' in older works. 13 September 1859 – 17 March 1919) was a Ukrainian-Russian explorer and zoologist who studied the flora and fauna of Central Asia. He was born in Gryakovo, Ukraine (then part of the Russian Empire). He wrote his first ornithology book in 1896 and made five expeditions in the Caspian region between 1884 and 1892. He led other expeditions to Persia supported by the Russian Geographical Society and the Zoological Museum of the Zoological Institute of the Russian Academy of Sciences. He collected nearly 3,140 specimens of birds and 50,000 insects. After the Russian Revolution, his collection was nationalized by the Bolsheviks and moved to the museum at the University of Tashkent. For his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Jacob Friedrich Wilhelm Parrot
Johann Jacob Friedrich Wilhelm Parrot (14 October 1791) was a Baltic German naturalist, explorer, and mountaineer, who lived and worked in Dorpat (today Tartu, Estonia) in what was then the Governorate of Livonia of the Russian Empire. A pioneer of Russian and Estonian scientific mountaineering, Parrot is best known for leading the first expedition to the summit of Mount Ararat in recorded history. Early career Born in Karlsruhe, in the Margraviate of Baden, Parrot was the son of Georg Friedrich Parrot, the first rector of the University of Dorpat (today the University of Tartu) and a close friend of Tsar Alexander I. He studied medicine and natural science at Dorpat and, in 1811, undertook an expedition to the Crimea and the Caucasus with Moritz von Engelhardt. There he used a barometer to measure the difference in sea level between the Caspian Sea and Black Sea. On his return he was appointed assistant doctor and, in 1815, surgeon in the Imperial Russian Army. In 1816 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hartert
Ernst Johann Otto Hartert (29 October 1859 – 11 November 1933) was a widely published German ornithologist. Life and career Hartert was born in Hamburg, Germany on 29 October 1859. In July 1891, he married the illustrator Claudia Bernadine Elisabeth Hartert in Frankfurt am Main, Germany, with whom he had a son named Joachim Karl (Charles) Hartert, (1893–1916), who was killed as an English soldier on the Somme. Together with his wife, he was the first to describe the blue-tailed Buffon hummingbird subspecies (''Chalybura buffonii intermedia'' Hartert, E & Hartert, C, 1894). The article ''On a collection of Humming Birds from Ecuador and Mexico'' appears to be their only joint publication. Hartert was employed by Walter Rothschild, 2nd Baron Rothschild as ornithological curator of Rothshild's private Natural History Museum at Tring, in England from 1892 to 1929. Hartert published the quarterly museum periodical ''Novitates Zoologicae'' (1894–39) with Rothschild, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Josef Prokop Pražák
Josef Prokop Pražák (22 June 1870 – 15 July 1904) was a Bohemian ornithologist. Life Born in Hořiněves he spent much of his life in Bohemia but also lived in Vienna, Edinburgh and for some time in Ukraine serving in the army. Because of problems in his research including the publication of false information and the submission of stolen specimens with fake data, much of his work remains under a cloud of uncertainty. Prazak researched the wild horses of the Ethiopian region at the University of Edinburgh between 1896 and 1897. He described the subspecies ''Equus quagga zambeziensis'' in his Edinburgh manuscript of 1898 (unpublished) which was cited by Trouessart who also noted the author for the name ''zambeziensis'' as Pražák. He published numerous works in ornithology but a lot of his work was doubted even during his lifetime. His records of the birds of Galicia included rarities and included a mass of collections that simply could not have been collected in the tim ...

Nominate
Nomination is part of the process of selecting a candidate for either election to a public office, or the bestowing of an honor or award. A collection of nominees narrowed from the full list of candidates is a short list. Political office In the context of elections for public office, a candidate who has been selected to represent or is endorsed by a political party is said to be the party's nominee. The process of selection may be based on one or more primary elections or by means of a political party convention or caucus, according to the rules of the party and any applicable election laws. In some countries the process is called preselection. Public statements of support for a candidate's nomination are known as endorsements or testimonials. In some jurisdictions the nominee of a recognized political party is entitled to appear on the general election ballot paper. Candidates who are endorsed by a political party may be required to submit a nominating petition in order to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parus
''Parus'' is a genus of Old World birds in the tit family. It was formerly a large genus containing most of the 50 odd species in the family Paridae. The genus was split into several resurrected genera following the publication of a detailed molecular phylogenetic analysis in 2013. The genus name, ''Parus'', is the Latin for "tit". Taxonomy The genus ''Parus'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The genus name is Latin for "tit". Of the 12 species included in the genus by Linnaeus, the type species was designated as the great tit (''Parus major'') by George Robert Gray in 1840. Species The genus now contains the following species: Fossil record *''Parus robustus'' (Pliocene of Csarnota, Hungary) Kessler, E. 2013. Neogene songbirds (Aves, Passeriformes) from Hungary. – Hantkeniana, Budapest, 2013, 8: 37-149. *''Parus parvulus'' (Pliocene of Csarnota, Hungary) *''Parus medius'' (Pliocene of Berem ...

DNA Sequence
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cytochrome B
Cytochrome b within both molecular and cell biology, is a protein found in the mitochondria of eukaryotic cells. It functions as part of the electron transport chain and is the main subunit of transmembrane cytochrome bc1 and b6f complexes. Function In the mitochondrion of eukaryotes and in aerobic prokaryotes, cytochrome b is a component of respiratory chain complex III () — also known as the bc1 complex or ubiquinol-cytochrome c reductase. In plant chloroplasts and cyanobacteria, there is an analogous protein, cytochrome b6, a component of the plastoquinone-plastocyanin reductase (), also known as the b6f complex. These complexes are involved in electron transport, the pumping of protons to create a proton-motive force ( PMF). This proton gradient is used for the generation of ATP. These complexes play a vital role in cells. Structure Cytochrome b/b6 is an integral membrane protein of approximately 400 amino acid residues that probably has 8 transmembrane segments. ...
