Starnoenas Cyanocephala
The blue-headed quail dove (''Starnoenas cyanocephala''), or blue-headed partridge-dove, is a species of bird in the pigeon and dove family Columbidae that is endemic to the island of Cuba. It is monotypic within the subfamily Starnoenadinae and genus ''Starnoenas''. Taxonomy In 1734 the English naturalist Eleazar Albin included a picture and a description of the blue-headed quail-dove in his ''A Natural History of Birds''. His drawing was made from a live bird that had been brought to England from the East Indies. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the 10th edition of Systema Naturae, tenth edition, he placed the blue-headed quail-dove with all the other pigeons in the genus ''Columba (genus), Columba''. Linnaeus included a brief description, coined the binomial name ''Columba cyanocephala'' and cited Albin's work. The specific epithet combines the Ancient Greek ''kuanos'' meaning "dark blue" and ''-kephalos'' meaning "-headed". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Gorget (bird)
A gorget ( ) is a patch of colored feathers found on the throat or upper breast of some species of birds. It is a feature found on many male hummingbirds, particularly those found in North America; these gorgets are typically iridescent. Other species, such as the purple-throated fruitcrow The purple-throated fruitcrow (''Querula purpurata'') is a species of bird in the family Cotingidae, the cotingas. It is the only species of the genus ''Querula''.Schulenberg, T. S., Ed. 2010Purple-throated Fruitcrow (''Querula purpurata'').Ne ... and chukar partridge, also show the feature. The term is derived from the gorget used in military armor to protect the throat (which is called ' in French). Feather wear and exposure to the sun can produce changes in the apparent color of iridescent gorget feathers. For example, fresh gorget feathers on the Anna's hummingbird are rose red; these fade to a coppery bronzy color with age. Functions A number of social functions have been sug ...

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 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 taxono ...

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.

Geophaps
''Geophaps'' is a small genus of doves. Established by George Robert Gray, it contains three extant species. The plumage and distribution suggests that all species within the genus have formed from a common ancestor and that through adaptive radiation they have varied greatly in size, shape and ecology. Taxonomy The genus ''Geophaps'' was introduced in 1842 to accommodate the squatter pigeon (''Geophaps scripta'') by the English zoologist George Robert Gray. The genus name combines of the Ancient Greek ''geō'' (γεω) meaning "ground" and ''phaps'' (φάψ), meaning "wild pigeon". Pigeons and doves are placed in their taxonomic groups based predominantly on structural characteristics. Pigeons feed their young by regurgitation and suck water while their beak is immersed. Males and females divide incubation duties. ''Geophaps'' pigeons are members of the family Columbidae, whose distribution is spread between three defined areas around the globe: the Americas; Africa, th ...

Australasia
Australasia is a subregion of Oceania, comprising Australia, New Zealand (overlapping with Polynesia), and sometimes including New Guinea and surrounding islands (overlapping with Melanesia). The term is used in a number of different contexts, including geopolitically, physiogeographically, philologically, and ecologically, where the term covers several slightly different but related regions. Derivation and definitions Charles de Brosses coined the term (as French ''Australasie'') in ''Histoire des navigations aux terres australes'' (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia (to the east) and the southeast Pacific ( Magellanica). In the late 19th century, the term Australasia was used in reference to the "Australasian colonies". In this sense it related specifically to the British colonies south of Asia: New South Wales, Queensland, South Australia, Tasmania, Western Australia, Victoria (i.e., the Australian colon ...

New World
The term "New World" is used to describe the majority of lands of Earth's Western Hemisphere, particularly the Americas, and sometimes Oceania."America." ''The Oxford Companion to the English Language'' (). McArthur, Tom, ed., 1992. New York: Oxford University Press, p. 33: "[16c: from the feminine of ''Americus'', the Latinized first name of the explorer Amerigo Vespucci (1454–1512). The name ''America'' first appeared on a map in 1507 by the German cartographer Martin Waldseemüller, referring to the area now called Brazil]. Since the 16th century, the term "New World" has been used to describe the Western Hemisphere, often referred to as the Americas. Since the 18th century, it has come to represent the United States, which was initially colonial British America until it established independence following the American Revolutionary War.
