Príncipe Kingfisher
The Príncipe kingfisher (''Corythornis cristatus nais'') is a bird in the family Alcedinidae. It is endemic to the island of Príncipe off the west coast of Africa in the Gulf of Guinea. The first formal description of the species was by the German naturalist Johann Jakob Kaup in 1848 who gave it the binomial name ''Alcedo nais''. A molecular phylogenetic study published in 2008 showed that the Príncipe kingfisher is a subspecies of the malachite kingfisher The malachite kingfisher (''Corythornis cristatus'') is a river kingfisher which is widely distributed in Africa south of the Sahara. It is largely resident except for seasonal climate-related movements. Taxonomy The malachite kingfisher was d ....

Johann Jakob Kaup
Johann Jakob von Kaup (10 April 1803 – 4 July 1873) was a German naturalist. A proponent of natural philosophy, he believed in an innate mathematical order in nature and he attempted biological classifications based on the Quinarian system. Kaup is also known for having coined popular prehistoric taxa like ''Pterosauria'', ''Machairodus'', ''Deinotherium'', ''Dorcatherium'', and ''Chalicotherium''. Biography He was born at Darmstadt. After studying at Göttingen and Heidelberg he spent two years at Rijksmuseum van Natuurlijke Historie, Leiden, where his attention was specially devoted to the amphibians and fishes. He then returned to Darmstadt as an assistant in the grand ducal museum, of which in 1840 he became inspector. In 1829 he published ''Skizze zur Entwickelungsgeschichte der europäischen Thierwelt'', in which he regarded the animal world as developed from lower to higher forms, from the amphibians through the birds to the beasts of prey; but subsequently he repudiated ...

Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Gulf Of Guinea
The Gulf of Guinea (French language, French: ''Golfe de Guinée''; Spanish language, Spanish: ''Golfo de Guinea''; Portuguese language, Portuguese: ''Golfo da Guiné'') is the northeasternmost part of the tropical Atlantic Ocean from Cape Lopez in Gabon, north and west to Cape Palmas in Liberia. Null Island, defined as the intersection of the Equator and Prime Meridian (zero degrees latitude and longitude), is in the gulf. Among the many rivers that drain into the Gulf of Guinea are the Niger River, Niger and the Volta River, Volta. The coastline on the gulf includes the Bight of Benin and the Bight of Bonny. Name "Guinea" is thought to have originated from a local name for an area in the region, although the specifics are disputed. Bovill (1995) gives a thorough description: The name "Guinea (region), Guinea" was also previously applied to the south coast of West Africa (north of the Gulf of Guinea), which became known as "Upper Guinea", and to the west coast of Southern Afri ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called 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 (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". 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 ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Malachite Kingfisher
The malachite kingfisher (''Corythornis cristatus'') is a river kingfisher which is widely distributed in Africa south of the Sahara. It is largely resident except for seasonal climate-related movements. Taxonomy The malachite kingfisher was described by the German naturalist Peter Simon Pallas in 1764 and given the binomial name ''Alcedo cristata''. The specific epithet ''cristata'' is from the Latin ''cristatus'' meaning "crested" or "plumed". The adjective "malachite" in the vernacular name normally refers to the dark green colour of the copper containing mineral. This kingfisher has blue upperparts but has black banding with pale blue or greenish-blue on its forehead. A molecular phylogenetic study published in 2007 confirmed that the most closely related species is the Malagasy kingfisher, (''Corythornis vintsioides''). The Malagasy kingfisher has a black bill and greenish crest, and is not quite as dependent on water as the African species. It is otherwise similar in plu ...

Corythornis
''Corythornis'' is a genus of small African river kingfishers. A molecular phylogenetic study of the alcedinine kingfishers published in 2007 found that the genera as then defined did not form monophyletic groups. The species were subsequently rearranged into four genera, with four species in the resurrected genus ''Corythornis''. The genus had been introduced by the German naturalist Johann Jakob Kaup in 1848. The type species is the Príncipe kingfisher (''Alcedo cristatus nais''). ''Corythornis'' is the sister group 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 ... to the genus '' Ispidina'' containing two small African kingfishers.
