Madagascar Green Pigeon
The Madagascar green pigeon (''Treron australis'') is a species of bird in the family Columbidae. It is found in Madagascar, Comoros, and Mayotte. The taxon ''griveaudi'', by most authorities considered a subspecies of the Madagascan green pigeon, is sometimes considered a separate species, the Comoros green pigeon (''Treron comorensis''). Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Madagascar green pigeon in his ''Ornithologie'' based on specimen that he had examined. He used the French name ''Le pigeon ramier verd de Madagascar'' and the Latin ''Palumbus viridis madagascariensis''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. The species was also illustrated in Edme-Louis Daubenton's ''Planches Enluminées D'Histoire Naturelle''. Although ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ankarafantsika National Park
Ankarafantsika National Park is a national park near Andranofasika in the Boeny Region of Madagascar. The closest city is Majunga north of the park. Ankarafantsika is mostly tropical in climate type. The Sakalava people are the predominant ethnic group living and farming here. The greater big-footed mouse (''Macrotarsomys ingens'') lives in the park and is not known anywhere else. The park The park is between the Betsiboka River to the west and the Mahajamba River to the east. Originally there were two parks on either side of Route 4 national road, but they were combined in 2002. The park occupies about 135,000 hectares and consists of patches of thick dry tropical forest interspersed with less dense areas. There are also savannah, scrub and sandy eroded rock areas and some land is farmed by the indigenous Sakalava people. There are a number of lakes and the park is criss-crossed by tracks and paths. There are lodging facilities and guides are available to help visitors appreci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Commission On Zoological Nomenclature
The International Commission on Zoological Nomenclature (ICZN) is an organization dedicated to "achieving stability and sense in the scientific naming of animals". Founded in 1895, it currently comprises 26 commissioners from 20 countries. Organization The ICZN is governed by the "Constitution of the ICZN", which is usually published together with the ICZN Code. Members are elected by the Section of Zoological Nomenclature, established by the International Union of Biological Sciences (IUBS). The regular term of service of a member of the Commission is six years. Members can be re-elected up to a total of three full six-year terms in a row. After 18 continuous years of elected service, a break of at least three years is prescribed before the member can stand again for election. Activities Since 2014, the work of the Commission is supported by a small secretariat based at the National University of Singapore, in Singapore. Previously, the secretariat was based in London and fun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar Dry Deciduous Forests
The Madagascar dry deciduous forests represent a tropical dry forest ecoregion situated in the western and northern part of Madagascar. The area has high numbers of endemic plant and animal species but has suffered large-scale clearance for agriculture. They are among the world's richest and most distinctive dry forests and included in the Global 200 ecoregions by the World Wide Fund. The area is also home to distinctive limestone karst formations known as tsingy, including the World Heritage Site of Bemaraha. Geography There are two separate areas within the ecoregion: the western side of Madagascar from the Ampasindava peninsula in the north to Belo-sur-Tsiribihina and Maromandia in the south (this is most of Mahajanga Province); and the northern tip of the island (apart from the high areas of Amber Mountain). Geological substrate is varied and includes the tsingy limestone massifs. These dry deciduous forests span the coastal plain with its limestone plateaus emanatin ...

Taxa Named By Carl Linnaeus
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 int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1771
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] |

Finn Salomonsen
Finn Salomonsen (31 January 1909 – 23 April 1983) was a Danish ornithologist. He is best known for his work on the birds of Greenland. His interest in Greenland began at the age of 16 when he made a trip with Lehn Schioler to the Upernavik District. He obtained a degree in zoology in 1932 and joined as a zoological assistant in the Danish Nature Reserves. He worked on migration of birds and moulting patterns extensively. During World War II he fled to Sweden with his family to escape persecution due to his Jewish ancestry. Salomonsen's work included over scientific publications, and authorship or co-authorship of 19 books. Apart from research in the Greenland and Arctic region, he went on expeditions to the Philippines (1951–1952) and to the Bismarck Archipelago, New Guinea (Noona Dan expedition, 1962). He was editor of the ''Dansk Ornithologisk Forenings Tidsskrift'' from 1942 to 1961. Finn Salomonsen was father of the Danish rock-singer Sanne Salomonsen Sanne Salomonsen ...

Louis Jean Pierre Vieillot
Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist. Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies and North America and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 77 of the genera erected by Vieillot are still in use. Biography Vieillot was born in Yvetot. He represented his family's business interests in Saint-Domingue (Haiti) on Hispaniola, but fled to the United States during the Haitian rebellions that followed the French Revolution. On Buffon's advice, he collected material for the ''Histoire naturelle des oiseaux de l'Amérique Septentrionale,'' the first two volumes of which were published in France beginni ...

Treron
''Treron'' is a genus of bird in the pigeon family Columbidae. Its members are commonly called green pigeons. The genus is distributed across Asia and Africa. This genus contains 30 species, remarkable for their green coloration, hence the common name, which comes from a carotenoid pigment in their diet. Green pigeons have diets of various fruits, nuts, and/or seeds. They dwell in trees and occupy a variety of wooded habitats. Members of this genus can be further grouped into species with long tails, medium-length tails, and wedge-shaped tails. Most species of green pigeon display sexual dimorphism, where males and females can be readily distinguished by different colored plumage. Behaviour Green pigeons usually live in groups but can be found in mating pairs. These birds like to live in wild environment, away from humans. But nowadays, it has been seen that these live on outskirts of cities and towns together with humans. Nesting Their nest is made up of twigs and little br ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...
