Linaria (bird)
''Linaria'' is a genus of small passerine birds in the finch family (Fringillidae) that contains the twite and the linnets. The genus name ''linaria'' is the Latin for a linen-weaver, from ''linum'', "flax". The species were formerly included in the genus ''Carduelis''. A molecular phylogenetic study using mitochondrial and nuclear DNA sequences published in 2012 found that the genus was polyphyletic. It was therefore split into monophyletic genera and the twite and the linnets moved to the resurrected genus ''Linaria''. The name had originally been introduced in 1802 by the German naturalist Johann Matthäus Bechstein Johann Matthäus Bechstein (11 July 1757 – 23 February 1822) was a German naturalist, forester, ornithologist, entomologist, and herpetologist. In Great Britain, he was known for his treatise on singing birds (''Naturgeschichte der Stubenvög .... Species The genus contains four species: References {{Taxonbar, from=Q11756901 Bird genera ...

Common Linnet
The common linnet (''Linaria cannabina'') is a small passerine bird of the finch family, Fringillidae. It derives its common name and the scientific name, ''Linaria'', from its fondness for hemp seeds and flax seeds—flax being the English name of the plant from which linen is made. Taxonomy In 1758, the Swedish naturalist Carl Linnaeus included the common linnet in the 10th edition of his ''Systema Naturae'' under the binomial name, ''Acanthis cannabina''. The species was formerly placed in the genus ''Carduelis'' but based on the results of a phylogenetic analysis of mitochondrial and nuclear DNA sequences published in 2012, it was moved to the genus ''Linaria'' that had been introduced by the German naturalist Johann Matthäus Bechstein in 1802. The genus name ''linaria'' is the Latin for a linen-weaver, from ''linum'', "flax". The species name ''cannabina'' comes from the Latin for hemp.

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Carduelis Cannabina -England -male-8
The genus ''Carduelis'' is a group of birds in the finch family Fringillidae. The genus ''Carduelis'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 by tautonomy based on Carl Linnaeus's specific epithet for the European goldfinch ''Fringilla carduelis''. The name ''carduelis'' is the Latin word for the European goldfinch. Many bird species were at one time assigned to the genus, but it became clear from phylogenetic studies of mitochondrial and nuclear DNA sequences that the genus was polyphyletic. The polyphyletic nature of the genus was confirmed by Dario Zuccon and coworkers in a comprehensive study of the finch family published in 2012. The authors suggested splitting the genus into several monophyletic clades, a proposal that was accepted by the International Ornithologists' Union. The siskins and goldfinches from the Americas formed a distinct clade and were moved to the resurrected genus '' Spinus'', the greenfinches were moved to the genus ''Ch ...

Twite
The twite (''Linaria flavirostris'') is a small brown passerine bird in the finch family Fringillidae. It is similar in size and shape to a linnet, at long. It lacks the red head patch and breast shown by the linnet and the redpolls. It is brown streaked with black above, and a pink rump. The underparts are buff to whitish, streaked with brown. The conical bill is yellow in winter and grey in summer. The call is a distinctive ''twit'', from which its name derives, and the song contains fast trills and twitters. Twites can form large flocks outside the breeding season, sometimes mixed with other finches on coasts and salt marshes. They feed mainly on seeds. The twite breeds in northern Europe and across the Palearctic to Siberia and China. Treeless moorland is favoured for breeding. It builds its nest in a bush, laying 5–6 light blue eggs. It is partially resident, but many birds migrate further south, or move to the coasts. It has declined sharply in parts of its range ...

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 ...

Mitochondrial
A mitochondrion (; ) is an organelle found in the cells of most Eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy. They were discovered by Albert von Kölliker in 1857 in the voluntary muscles of insects. The term ''mitochondrion'' was coined by Carl Benda in 1898. The mitochondrion is popularly nicknamed the "powerhouse of the cell", a phrase coined by Philip Siekevitz in a 1957 article of the same name. Some cells in some multicellular organisms lack mitochondria (for example, mature mammalian red blood cells). A large number of unicellular organisms, such as microsporidia, parabasalids and diplomonads, have reduced or transformed their mitochondria into other structures. One eukaryote, ''Monocercomonoides'', is known to have completely lost its mitochondria, and one multicellular organism, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Matthäus Bechstein
Johann Matthäus Bechstein (11 July 1757 – 23 February 1822) was a German naturalist, forester, ornithologist, entomologist, and herpetologist. In Great Britain, he was known for his treatise on singing birds (''Naturgeschichte der Stubenvögel'', ''Natural History of Cage Birds'', 1795). Biography Bechstein was born in Waltershausen in the district of Gotha in Thuringia. He studied theology for four years at the University of Jena, and spent time hunting and roaming the forests as opportunities permitted. After leaving school, he taught for some years, but gave teaching up to devote himself to outdoor pursuits. In 1795, he founded the school of forestry at Waltershausen, and in 1800, the Duke of Saxe-Meiningen made him the director of the forestry school at Dreissigacker near Meiningen in the neighbouring district of Schmalkalden-Meiningen. After the death of his own son, Bechstein adopted his nephew Ludwig Bechstein. Bechstein was a prolific zoologist and one of the first ...

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.
