Blue Tit
The Eurasian blue tit (''Cyanistes caeruleus'') is a small passerine bird in the tit (bird), tit family, Paridae. It is easily recognizable by its blue and yellow plumage and small size. Eurasian blue tits, usually resident bird, resident and bird migration, 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 (''Parus major''). 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 noted 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 ...

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. 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 (mathematics), 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 ...

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] |
Josef Prokop Pražák
Josef Prokop Pražák (22 June 1870 – 15 July 1904) was a Bohemian ornithologist. Because of problems in his research including publication of false information and the submission of stolen specimens with fake data, much of his work remains under a cloud of uncertainty. ed to Edinburgh again, he was declared a Doctor of Natural Sciences there. After this, he engaged in further scientific activity in the natural science institutes of this university and achieved a distinguished name there, and was offered a professorship in the college of Calcutta, India. But military duty prevented him from this mission, as a reserve officer he had to return home and therefore declined the position. He then settled in Prague, where he took the post of prefect at Straka's Noble Academy and taught French and English there. At the same time, however, he continued to study privately and prepared for publication a comprehensive English book on ungulates. In order to have more time for this work, he l ...

Cline (biology)
In biology, a cline is a measurable gradient in a single characteristic (or biological trait) of a species across its geographical range. Clines usually have a genetic (e.g. allele frequency, blood type), or phenotypic (e.g. body size, skin pigmentation) character. They can show either smooth, continuous gradation in a character, or more abrupt changes in the trait from one geographic region to the next. A cline is a spatial gradient in a single specific trait, rather than in a collection of traits; a single population can therefore have as many clines as it has traits, at least in principle. Additionally, as Julian Huxley recognised, these multiple independent clines may not act in concordance with each other. For example, it has been observed that in Australia, birds generally become smaller the further towards the north of the country they are found. In contrast, the intensity of their plumage colouration follows a different geographical trajectory, being most vibrant where ...

Azure Tit
The azure tit (''Cyanistes cyanus'') is a passerine bird in the tit family Paridae. It is a widespread and common resident breeder throughout Russia, Central Asia, northwest China, Manchuria, and Pakistan. It is found in temperate and subarctic deciduous or mixed woodlands, scrub, and marshes. It is a resident species, and most birds do not migrate. It nests in tree holes, laying approximately 10 eggs. The bird is a close sitter, displaying defensive behaviors such as hissing and biting when disturbed. Its diet primarily consists of insects, seeds, small invertebrates, bug larvae, and eggs. This bird is unmistakable. Its head, tail corners, wing bars, and underparts are white, while the upperparts are blue. It has a distinctive dark line running through its eye. This bird is the eastern counterpart of the common Eurasian blue tit. It will hybridise with that species, but the offspring usually show a blue crown, rather than the white of azure tit. The calls are similar to blue ... [...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 soc ... [...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 classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, 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 Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parus
''Parus'' is a genus of Old World birds in the tit family Paridae. 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 word 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 three 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) *'' Par ...

DNA Sequence
A nucleic acid sequence is a succession of bases within the nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. This succession is denoted by a series of a set of five different letters that indicate the order of the nucleotides. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, with its double helix, there are two possible directions for the notated sequence; of these two, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence represents genetic information. Biological deoxyribonucleic acid represents the information which directs the functions of an organism. Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as "prim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cytochrome B
Cytochrome b is a protein found in the membranes of aerobic cells. In eukaryotic mitochondria (inner membrane) 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 a homologous 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 and function Cytochrome b/b6 is an integral membrane protein of approximately 400 amino acid residues that probably has 8 transmembrane segments. In plants and cyanobacteria, cytochrome b6 consists of two protein subunits encoded by the petB and petD genes. Cytochrome b/b6 non-covalently binds two heme ...

MtDNA
Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine triphosphate (ATP). Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. Mitochondrial DNA is responsible for coding of 13 essential subunits of the complex oxidative phosphorylation (OXPHOS) system which has a role in cellular energy conversion. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits tra ...
