Red-moustached Fruit Dove
The red-moustached fruit dove or moustached fruit dove (''Ptilinopus mercierii'') is an extinct species of bird in the family Columbidae. It was endemic to French Polynesia. The last record was of the subspecies ''P. m. tristrami'' on Hiva Oa, in 1922. Its extinction has been attributed to predation by the introduced great horned owl ('' Bubo virginianus''), as well as by introduced rats and cats. In 1994, it was listed as an extinct species on the International Union for Conservation of Nature Red List of Endangered Species. Description The red-moustached fruit dove measured in length. The head, breast, and neck were bluish grey, and the tail was short, almost square shaped. The underpart plumage was golden yellow in colour. The juvenile had less yellow on the hind neck and crown. The breast was green-tinged and had light yellowish on the peripheries of the feathers. The undertail coverts were yellow-white. It was similar in appearance with the white-capped fruit ...

Marc Athanase Parfait Œillet Des Murs
Marc Athanase Parfait Œillet des Murs ( Paris, 18 April 1804 – Nogent-le-Rotrou, 25 February 1894) was a French amateur ornithologist and local politician and historian. Life His parents were Jacques Philippe Athanase Œillet Des Murs and Marie Henriette Gard. He entered the magistracy in 1830 and left it in 1838. In 1841 he became a lawyer in the Court of Cassation, but in 1846 retired to the department of Eure-et-Loir, where in 1843 he had bought a castle called the Château St. Jean near the town of Nogent-le-Rotrou and begun extensive restoration work on it. He was the mayor of Nogent-le-Rotrou from 1860 to 1868. In 1885, having sunk a good deal of his fortune into the restoration of the Château, he sold it. He married Caroline Euphrasie Naulot, who survived him. Ornithology He published many papers. His major ornithological works include *''Iconographie Ornithologique'', (1849), a book of illustrations and descriptions of birds. *The ornithological section of ...

Nominate Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( 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 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 ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Florent Prévost
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1849
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extinct Birds Of Oceania
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ptilinopus
The fruit doves, also known as fruit pigeons, are a genus (''Ptilinopus'') of birds in the pigeon and dove family (Columbidae). These colourful, frugivorous doves are found in forests and woodlands in Southeast Asia and Oceania. It is a large genus with over 50 species, some threatened or already extinct. Taxonomy The genus ''Ptilinopus'' was introduced in 1825 by the English naturalist William John Swainson with the rose-crowned fruit dove (''Ptilinopus regina'') as the type species. The genus name combines the Ancient Greek meaning "feather" with meaning "foot". The many species of this genus can be further grouped by geography and by certain shared characteristics. The fruit doves of the Sunda Islands and northern Australia, such as the pink-headed fruit dove and banded fruit dove, have comparatively longer tails than other species, and are notable for their solid colouration on the head, neck and breast, with a black band across the belly. Another grouping can be made o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List of Endangered Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Forests
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuku Hiva
Nuku Hiva (sometimes spelled Nukahiva or Nukuhiva) is the largest of the Marquesas Islands in French Polynesia, an overseas country of France in the Pacific Ocean. It was formerly also known as ''Île Marchand'' and ''Madison Island''. Herman Melville wrote his book '' Typee'' based on his experiences in the Taipivai valley in the eastern part of Nuku Hiva. Robert Louis Stevenson's first landfall on his voyage on the ''Casco'' was at Hatihe'u, on the north side of the island, in 1888. Geography Coast Western Nuku Hiva is characterized by a steep but fairly regular coastline, indented occasionally by small bays, leading to deep valleys, which in turn lead into the interior. There are no villages on the western side. The coastline of the eastern part of the island has few places to land by sea and takes the brunt of the ocean swells. The northern side, in contrast, is indented by deep bays, the largest of which are Anahō and Hatihe'u. A third bay, 'A'akapa, is smaller ...
