Columba Malherbii
The island bronze-naped pigeon (''Columba malherbii''), also known as the São Tomé bronze-naped pigeon, is a species of bird in the family Columbidae. It is endemic to the Gulf of Guinea islands of Annobón (Equatorial Guinea), São Tomé and Príncipe (São Tomé and Príncipe). Its natural habitat is subtropical or tropical moist lowland forest. It is part of the subgenus ''Turturoena''. The species of birds was described by Jules and Edouard Verreaux in 1851. Conservation The species has been classified as Near Threatened by the IUCN due to substantial hunting pressure, which may be increasing. While the island bronze-naped pigeon is able to make use of secondary vegetation and somewhat degraded habitats, it also may be captured more easily in such areas than in dense vegetation.

São Tomé
São Tomé is the capital and largest city of the Central African island country of São Tomé and Príncipe. Its name is Portuguese for " Saint Thomas". Founded in the 15th century, it is one of Africa's oldest colonial cities. History Álvaro Caminha founded the colony of São Tomé in 1493. The Portuguese came to São Tomé in search of land to grow sugarcane. The island was uninhabited before the arrival of the Portuguese sometime around 1470. São Tomé, situated about north of the equator, had a climate wet enough to grow sugarcane in wild abundance. 2,000 Jewish children, eight years old and under, were taken from the Iberian peninsula for work on the sugar plantations. The nearby African Kingdom of Kongo eventually became a source of slave labor as well. The island of São Tomé was the main center of sugar production in the sixteenth century; it was overtaken by Brazil by 1600. São Tomé is centred on a sixteenth-century cathedral, that was largely rebuilt in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and 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 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 light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of The Gulf Of Guinea
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. Bird ...

Columba (genus)
The large bird genus ''Columba'' comprises a group of medium to large pigeons. The terms "dove" and "pigeon" are used indiscriminately for smaller and larger Columbidae, respectively. ''Columba'' species – at least those of ''Columba sensu stricto'' – are generally termed "pigeons", and in many cases wood-pigeons. The rock dove (''C. livia''), has given rise to the majority of domesticated pigeon breeds, such as the racing pigeon and the fantail pigeon some of which have become feral. Meanwhile, "wood pigeon" by itself usually means the common wood pigeon (''C. palumbus''). This genus as understood today is native to the Old World, but some – notably the domestic and feral rock pigeon – have been introduced outside their natural range, for example in the Americas. Etymology The term ''columba'' comes from the Latin ''columba'', "a dove", the feminine form of ''columbus'', "a male dove", itself the latinisation of the Greek κόλυμβος (''kolumbos' ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

Subtropical Or Tropical Moist Lowland Forest
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature. Description TSMF is generally found in large, discontinuous patches centered on the equatorial belt and between the Tropic of Cancer and Tropic of Capricorn, TSMF are characterized by low variability in annual temperature and high levels of rainfall of more than annually. Forest composition is dominated by evergreen and semi-deciduous tree species. These trees number in the thousands and contribute to the highest levels of species diversity in any terrestrial major habitat type. In general, biodiversity is highest in the forest canopy. The canopy can be divided into five layers: overstory canopy with emergent crowns, a medium layer of canopy, lower canopy, shrub level, and finally understory. These forests are home to more species than any other terrestrial ecosystem: Half of the world's sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jules Verreaux
Jules Pierre Verreaux (24 August 1807 – 7 September 1873) was a French botanist and ornithologist and a professional collector of and trader in natural history specimens. He was the brother of Édouard Verreaux and nephew of Pierre Antoine Delalande. Career Verreaux worked for the family business, Maison Verreaux, established in 1803 by his father, Jacques Philippe Verreaux, at Place des Vosges in Paris, which was the earliest known company that dealt in objects of natural history. The company funded collection expeditions to various parts of the world. Maison Verreaux sold many specimens to the Muséum National d'Histoire Naturelle to add to its collections. In 1830, while travelling in modern-day Botswana, Verreaux witnessed the burial of a Tswana warrior. Verreaux returned to the burial site under cover of night to dig up the African's body where he retrieved the skin, the skull and a few bones. Verreaux intended to ship the body back to France and so prepared and preser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
