Tangara Arthus
The golden tanager (''Tangara arthus'') is a species of bird in the family Thraupidae. It is widespread and often common in highland forests of the Andes (from Bolivia and northwards) and Venezuelan Coastal Range in north-western South America. Its plumage is overall golden-yellow with black to the back, wings, tail and ear-coverts. Some subspecies are partially/largely brown below. Taxonomy and systematics The golden tanager was first described as ''Tangara Arthus'' by René Lesson in 1840 on the basis of a specimen from Caracas, Venezuela. The generic name ''Tangara'' comes from the Tupí word ''tangara'', meaning dancer. The specific name ''arthus'' is in honor of Arthus Bertrand, a French bookseller. Golden tanager is the official common name designated by the International Ornithologists' Union (IOC). Other names for the species include "chestnut-breasted tanager". The golden tanager is one of 27 species in the genus '' Tangara''. Within the genus, it is part of a species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cali
Santiago de Cali (), or Cali, is the capital of the Valle del Cauca department, and the most populous city in southwest Colombia, with 2,227,642 residents according to the 2018 census. The city spans with of urban area, making Cali the second-largest city in the country by area and the third most populous after Bogotá and Medellín. As the only major Colombian city with access to the Pacific Coast, Cali is the main urban and economic center in the south of the country, and has one of Colombia's fastest-growing economies.

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Cladogram
A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other evolutionary narratives about ance ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Flame-faced Tanager
The flame-faced tanager (''Tangara parzudakii'') is a species of bird in the tanager family Thraupidae. It is endemic to South America and is found in the eastern Andes of Colombia, Ecuador, Peru and Venezuela. Its natural habitat is subtropical or tropical moist montane forests. It is a distinctive-looking species with black and opalescent green upperparts, opalescent green and buff underparts, and a deep red and yellow face. The subspecies ''lunigera'' lacks the deep red on the face, which is replaced with orangish-red. It is omnivorous and feeds on fruit and arthropods. Foraging is conducted nearly exclusively on mossy branches. Breeding occurs in the rainy season. Eggs are laid in clutches of two, and are white with pale brown flecking concentrated on the larger end. Fledglings are fed by both parents. The flame-faced tanager is listed as being of least concern by the International Union for Conservation of Nature (IUCN) on the IUCN Red List. However, it is facing population ...

Golden-eared Tanager
The golden-eared tanager (''Tangara chrysotis'') is a species of bird in the tanager family Thraupidae. It is found in the eastern Andes of Bolivia, Colombia, Ecuador and Peru where its natural habitat is subtropical or tropical moist montane forests. Taxonomy and systematics The golden-eared tanager was first described as ''Calliste chrysotis'' by Bernard du Bus de Gisignies in 1846, on the basis of a specimen collected from Peru. The generic name ''Tangara'' comes from the Tupí word ''tangara'', which means dancer. The specific name ''chrysotis'' is from the Ancient Greek χρυσος (''khrusos''), meaning golden, and ωτις (''otis''), meaning eared. Golden-eared tanager is the official common name designated by the International Ornithologists' Union (IOC). Other names for the species include golden eared tanager.
