Grey-headed Chickadee
The grey-headed chickadee or Siberian tit (''Poecile cinctus''), formerly ''Parus cinctus'', is a passerine bird in the tit family Paridae. It is a widespread resident breeder throughout subarctic Scandinavia and the northern Palearctic, and also into North America in Alaska and the far northwest of Canada. It is a conifer specialist. It is resident, and most birds do not migrate. Curiously (with respect to its name), the bird has no grey on its head, which is black, white, and brown. It is a fairly large tit, 13.5–14 cm long with a weight of 11–14.3 g. The head is dark brown with white cheeks, the mantle brown, the wing feathers blackish with pale fringes, and the underparts whitish with pale brown flanks. Ecologists in Folldal, Hedmark, Norway found that the Siberian tits accounted for only 1% of all tit individuals in lichen-dominated pine forest in 2011 as opposed to 64% in 1982. This dramatic reduction is attributed to the interspecies competition with the wil ...

Pieter Boddaert
Pieter Boddaert (1730 – 6 May 1795) was a Dutch physician and natural history, naturalist. Early life, family and education Boddaert was the son of a Middelburg jurist and poet by the same name (1694–1760). The younger Pieter obtained his M.D. at the University of Utrecht in 1764. Career He became a lecturer on natural history at his alma mater, University of Utrecht. Fourteen letters survive of his correspondence with Carl Linnaeus between 1768 and 1775. He was a friend of Albert Schlosser, whose Cabinet of curiosities, cabinet of "curiosities" of natural history he described. In 1783 he published 50 copies of an identification key of Edmé-Louis Daubenton's ''Planches enluminées'', the colored plates of illustrations for the comte de Buffon's monumental ''Histoire Naturelle'' (published 1749–1789), assigning binomial scientific names to the plates. As many of these were the first Linnaean taxonomy, Linnaean scientific names to be proposed, they remain in use. In 2017 the ...

Poecile
''Poecile'' is a genus of birds in the tit family Paridae. It contains 15 species, which are scattered across North America, Europe and Asia; the North American species are the chickadees. In the past, most authorities retained ''Poecile'' as a subgenus within the genus ''Parus'', but treatment as a distinct genus, initiated by the American Ornithologists Union, is now widely accepted. This is supported by mtDNA cytochrome ''b'' sequence analysis. The genus ''Poecile'' was erected by the German naturalist Johann Jakob Kaup in 1829. The type species was subsequently designated as the marsh tit (''Poecile palustris'') by English zoologist George Robert Gray in 1842. The name ''Poecile'' is from Ancient Greek ''poikilos'' "colourful". A related word ''poikilidos'' denoted an unidentified small bird. It has traditionally been treated as feminine (giving name endings such as ''cincta''); however, this was not specified by the original genus author Johann Jakob Kaup, and under the ...

Birds Of North Asia
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. Bird ...

James Francis Stephens
James Francis Stephens (16 September 1792 – 22 December 1852) was an English entomologist and naturalist. He is known for his 12 volume ''Illustrations of British Entomology'' (1846) and the ''Manual of British Beetles'' (1839). Early life Stephens was born in Shoreham-by-Sea and studied at Christ's Hospital. His father was a navy captain William James Stephens (d. 1799) and his mother was Mary Peck (later Mrs Dallinger). He went to school at the Blue Coat School, Hertford and later at Christ's Hospital, London. He was then sent to study under Shute Barrington (1734–1826), the bishop of Durham in 1800. He left in 1807 and worked as a clerk in the Admiralty office, Somerset House, from 1807 to 1845 thanks to his uncle Admiral Stephens. Entomology Stephens took an interest in natural history even as a schoolboy. He wrote a manuscript ''Catalogue of British Animals'' in 1808. He was elected fellow of the Linnean Society on 17 February 1815, and of the Zoological Society o ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross 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 Friedrich Burdach ...

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 ...

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. ...
