Ptilopachus
''Ptilopachus'' is an African genus of birds in the New World quail family. Taxonomy The genus ''Ptilopachus '' was introduced in 1837 by the English naturalist William Swainson to accommodate a single species, the stone partridge, which is therefore the type species. The genus name is from Ancient Greek ''ptilon'' meaning "feather" with ''pakhus'' meaning "thick" or "dense". As traditionally defined, only the stone partridge was included in this genus, but based on Genetics, genetic evidence, it now also includes Nahan's partridge (formerly considered a francolin). The study also concludes that this genus is more closely related to the New World quails (Odontophoridae) and might be considered their only African representative. Description At about in length, both are relatively small, Terrestrial animal, terrestrial birds with a red eye-ring, base of the bill, and legs, and brownish upperparts.McGowan, P. J. K. (1994).

Stone Partridge
The stone partridge (''Ptilopachus petrosus'') is a bird of the Odontophoridae, New World quail family. This largely brown bird, which commonly holds its tail raised, is found in scrubland and lightly wooded habitats, often near rocks, from Kenya and Ethiopia to Gambia (a large part if its range is in the Sudanian Savanna). Taxonomy The stone partridge was Species description, formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with all the other partridge like birds in the genus ''Tetrao'' and coined the binomial nomenclature, binomial name ''Tetrao petrosus''. Gmelin's description was based on the Georges-Louis Leclerc, Comte de Buffon, Comte de Buffon's "Le perdrix de roche ou de la Gambia" and John Latham (ornithologist), John Latham's "Rufous-breasted partridge". The stone partridge is now placed with Nahan's partridge in the genus ''Ptilopachus'' that was introd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nahan's Partridge
Nahan's partridge (''Ptilopachus nahani''), also known as the Nahan's francolin, is a bird traditionally placed in the family Phasianidae. As suggested by its alternative name, it was formerly believed to be a francolin and placed either in ''Francolinus'' or ''Pternistis'', but it is now known that its closest relative is the stone partridge and together may in fact be the only African representatives of the New World quails (Odontophoridae).Crowe, T.

Description At about in length, the Nahan's partridge is a relatively small, terrestrial bird with a red eye-ring, legs and base of the bill, brownish upperparts, and black-and-white underparts and head.

New World Quail
The New World quail are small birds, that despite their similar appearance and habits to the Old World quail, belong to a different family known as the Odontophoridae. In contrast, the Old World quail are in the Phasianidae family, sharing only a remote phylogenetic connection with their New World counterparts through their mutual classification within the Phasianoidea superfamily. The geographical range of the New World quail extends from Canada to southern Brazil, and two species, the California quail and the bobwhite quail, have been successfully introduced species, introduced to New Zealand. The stone partridge and Nahan's partridge, both found in Africa, seem to belong to the family. Species are found across a variety of habitats from tropical rainforest to deserts, although few species are capable of surviving at very low temperatures. There are 34 species divided into 10 genus, genera. The legs of most New World quails are short but powerful, with some species having very t ...

Francolin
Francolins are birds in the tribe Gallini that traditionally have been placed in the genus ''Francolinus'', but now commonly are divided into multiple genera. As previously defined, they were paraphyletic as the genus '' Pternistis'', which was previously included in '' Francolinus'', is more closely related to Old World quails than it is to the other francolins. Beginning in 2004, various ornithologists have recommended that it would be clearer to use "spurfowl" for all members of the genus ''Pternistis'' and restrict the use of "francolin" to the other species presently or formerly classified in '' Francolinus''. When ''Pternistis'' is excluded, the francolins form a monophyletic clade that is a sister group to a clade comprising the junglefowl (''Gallus'') and the bamboo partridges (''Bambusicola''); together, these clades compose the tribe Gallini. Although formerly classified in the partridge subfamily Perdicinae, this classification is no longer supported, and they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

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] |
Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinians, Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Phenotypic trait, Trait inheritance and Molecular genetics, molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the Cell (bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
