Buttonquail
Buttonquail or hemipodes are members of a small family of birds, Turnicidae, which resemble, but are not closely related to, the quails of Phasianidae. They inhabit warm grasslands in Asia, Africa, Europe, and Australia. There are 18 species in two genera, with most species placed in the genus '' Turnix'' and a single species in the genus '' Ortyxelos''. Buttonquails are small, drab, running birds, which avoid flying. The female is the more richly colored of the sexes. While the quail-plover is thought to be monogamous, ''Turnix'' buttonquails are sequentially polyandrous: both sexes cooperate in building a nest in the earth, but normally only the male incubates the eggs and tends the young, while the female may go on to mate with other males. Taxonomy The genus ''Turnix'' was introduced in 1791 by French naturalist in Pierre Bonnaterre. The genus name is an abbreviation of the genus '' Coturnix''. The type species was subsequently designated as the common buttonquail. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Buttonquail
The common buttonquail (''Turnix sylvaticus''), also called Kurrichane buttonquail and Andalusian hemipode, is a buttonquail, one of a small family of birds that resemble but are not closely related to the true quails. Taxonomy The common buttonquail was formally described and illustrated in 1789 by the French botanist René Louiche Desfontaines under the binomial name ''Tetrao sylvaticus''. The specific epithet ''sylvaticus'' is Latin meaning "of the woods". It is now placed in the genus ''Turnix'' that was named in 1840 by Pierre Joseph Bonnaterre. Nine subspecies are recognised: * ''T. s. sylvaticus'' ( Desfontaines, 1789) – the southern Iberian Peninsula and northwestern Africa * ''T. s. lepurana'' ( Smith, A, 1836) – Africa south of the Sahara * ''T. s. dussumier'' (Temminck, 1828) – eastern Iran to Myanmar * ''T. s. davidi'' Delacour & Jabouille, 1930 – central Thailand to southern China, northern Indochina and Taiwan * ''T. s. bartelsorum'' Neumann, 1929 – Ja ...

Gruiformes
The Gruiformes ( ) are an order containing a considerable number of living and extinct bird families, with a widespread geographical diversity. Gruiform means "crane-like". Traditionally, a number of wading and terrestrial bird families that did not seem to belong to any other order were classified together as Gruiformes. These include 15 species of large cranes, about 145 species of smaller crakes and rails, as well as a variety of families comprising one to three species, such as the Heliornithidae, the limpkin, or the Psophiidae. Other birds have been placed in this order more out of necessity to place them ''somewhere''; this has caused the expanded Gruiformes to lack distinctive apomorphies. Recent studies indicate that these "odd Gruiformes" are if at all only loosely related to the cranes, rails, and relatives ("core Gruiformes"). Systematics There are only two suprafamilial clades (natural groups) among the birds traditionally classified as Gruiformes. Rails ( Ra ...

Charadriiformes
Charadriiformes (, from '' Charadrius'', the type genus of family Charadriidae) is a diverse order of small to medium-large birds. It includes about 390 species and has members in all parts of the world. Most charadriiform birds live near water and eat invertebrates or other small animals; however, some are pelagic (seabirds), others frequent deserts, and a few are found in dense forest. Members of this group can also collectively be referred to as shorebirds. Taxonomy, systematics and evolution The order was formerly divided into three suborders: * The waders (or "Charadrii"): typical shorebirds, most of which feed by probing in the mud or picking items off the surface in both coastal and freshwater environments. * The gulls and their allies (or " Lari"): these are generally larger species which take fish from the sea. Several gulls and skuas will also take food items from beaches, or rob smaller species, and some have become adapted to inland environments. * The auks (or "Al ...

Quail-plover
The quail-plover, lark buttonquail or lark-plover (''Ortyxelos meiffrenii'') is a small ground-living bird in the buttonquail family Turnicidae that is found in the Sahel region of Africa and in a disjunct region of East Africa. It is the only species placed in the genus ''Ortyxelos''. Description The quail-plover is a small, short-tailed cursorial bird which slightly resembles a miniature courser when on the ground. The upperparts are a sandy-rufous colour and the underparts mainly whitish. They show a distinctive wing pattern in flight when the contrast between the white primary coverts and the black with white-tipped remiges to form a distinct diagonal band on the upperwing. Its fluttering flight style is rather lark-like. The females are slightly darker than the males while the juveniles are paler. Distribution and habitat The quail-plover occurs in Sahel from southern Mauritania and northern Senegal eastwards to northern Cameroon and southern Chad into South Sudan and sou ...

Galliformes
Galliformes is an order (biology), order of heavy-bodied ground-feeding birds that includes turkey (bird), turkeys, chickens, Old World quail, quail, and other landfowl. Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds. The order contains about 290 species, inhabiting every continent except Antarctica, and divided into five Family (biology), families: Phasianidae (including chicken, quail, partridges, pheasants, turkeys, peafowl (peacocks) and grouse), Odontophoridae (New World quail), Numididae (guinea fowl), Cracidae (including chachalacas and curassows), and Megapodiidae (incubator birds like malleefowl and Brushturkey, brush-turkeys). They adapt to most environments except for innermost deserts and perpetual ice. Many gallinaceous species are skilled runners and escape predators by running rather than flying. Males of most species a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coturnix
''Coturnix'' is a genus of five extant species and five to eight known extinct species of Old World quail. Range These species are distributed throughout Africa, Eurasia, Australia, and formerly New Zealand. An extinct Adaptive radiation, radiation of Flightless bird, flightless, insular species is known through fossil remains from Macaronesia, which were likely wiped out by human arrival. Habits Quail of ''Coturnix'' live in pairs or small social groups and form larger groups during migration. Not all species migrate, but most are capable of extremely rapid, upward flight to escape from danger. Unlike related genera, Old World quail do not perch in trees. They devote much of their time to scratching and foraging for seeds and invertebrates on the ground. Typical habitats are dense vegetation such as grasslands, bushes alongside rivers and cereal fields. They are heavily predated upon by Accipitriformes, diurnal hawks. Taxonomy The genus ''Coturnix'' was introduced in 1764 by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DNA Sequence
A nucleic acid sequence is a succession of bases within the nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. This succession is denoted by a series of a set of five different letters that indicate the order of the nucleotides. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, with its double helix, there are two possible directions for the notated sequence; of these two, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence represents genetic information. Biological deoxyribonucleic acid represents the information which directs the functions of an organism. Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as "prim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Evolution
Molecular evolution describes how Heredity, inherited DNA and/or RNA change over evolutionary time, and the consequences of this for proteins and other components of Cell (biology), cells and organisms. Molecular evolution is the basis of phylogenetics, phylogenetic approaches to describing the Tree of life (biology), tree of life. Molecular evolution overlaps with population genetics, especially on shorter timescales. Topics in molecular evolution include the origins of new genes, the genetic nature of complex traits, the genetic basis of adaptation and speciation, the Evolutionary developmental biology, evolution of development, and patterns and processes underlying genome, genomic changes during evolution. History The history of molecular evolution starts in the early 20th century with comparative biochemistry, and the use of "fingerprinting" methods such as immune assays, gel electrophoresis, and paper chromatography in the 1950s to explore homologous proteins.
