Bannerman's Turaco
Bannerman's turaco (''Tauraco bannermani'') is a species of bird in the family Musophagidae. It is endemic to Cameroon. In French it is known as ''touraco de Bannerman'' or ''touraco doré''. Its scientific and common names honour the ornithologist David Armitage Bannerman. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat destruction and the International Union for Conservation of Nature has listed it as an "endangered species". Taxonomy The Bannerman's turaco was first described in 1923 by the American naturalist George Latimer Bates. Genetic studies show that this species is closely related to the red-crested turaco (''Tauraco erthrolophus'') and white-crested turaco (''Tauraco leucolophus''), having diverged from them in the late Pliocene. At that time, climatic changes occurred which subsequently led to increasingly arid conditions, a decrease in forest cover and an increase in wooded savannah. The white-crested turaco mainta ...

George Latimer Bates
George Latimer Bates (March 21, 1863, Abingdon, Illinois US – January 31, 1940 Chelmsford UK), LL.D., M.B.O.U. was an American naturalist. Bates studied at Knox College, Galesburg and at the Chicago Theological Seminary and in 1895 visited West Africa and lived in the south east Cameroon, making a living by farming. He collected natural history specimens in his travels and sent many of these to the Natural History Museum in London. In 1928 Bates moved to England and wrote a ''Handbook on the Birds of West Africa'' (1930). He learned Arabic and visited Arabia in 1934 and studied the ornithology of Arabia. He was unable to publish the work but wrote several papers on Arabian birds for the ''Ibis''. His unpublished manuscript on the ''Birds of Arabia'' was later used by Richard Meinertzhagen.

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...

Birds Described In 1923
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 endemism, 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 Water bird, waterbirds, have further evolve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Cameroon
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tauraco
''Tauraco'' is a genus of turacos. It contains the "typical" or green turacos; though their plumage is not always green all over, the presence of significant amounts of turacoverdin-colored plumage generally sets ''Tauraco'' species apart from other Musophagidae. Indeed, as opposed to any other known birds, ''Tauraco'' turacos are the only living bird taxa that have any significant green pigment whatsoever, as the greens of many parrots etc. are due to structural color, not pigment. Their genus name was derived from a native Niger–Congo languages, West African name. Taxonomy The genus ''Tauraco'' was introduced in 1779 by the Polish naturalist Jan Krzysztof Kluk. The type species was later designated as the Guinea turaco. Species The genus contains 13 species. References External links * * {{Taxonbar, from=Q654783 Tauraco, Bird genera ...

Firewood
Firewood is any wooden material that is gathered and used for fuel. Generally, firewood is not highly processed and is in some sort of recognizable log or branch form, compared to other forms of wood fuel like pellets or chips. Firewood can be seasoned and heat treated (dry) or unseasoned (fresh/wet). It is generally classified as hardwood or softwood. Firewood is a renewable resource. However, demand for this fuel can outpace its ability to regenerate on a local or regional level. Good forestry practices and improvements in devices that use firewood can improve local wood supplies. Moving firewood long distances can potentially transport diseases and invasive species. History For most of human history firewood was the main fuel, until the use of coal spread during the Industrial Revolution. As such, access to firewood was a valued resource, wood botes or the right to gather firewood being a significant aspect of many medieval leases. As late as 19th C America, Thoreau ...

Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire(bushfires in Australia, in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...

Western High Plateau
The Western High Plateau, Western Highlands or Bamenda Grassfields is a region of Cameroon characterised by high relief, cool temperatures, heavy rainfall and savanna vegetation. The region lies along the Cameroon line and consists of mountain ranges and volcanoes made of crystalline and igneous rock. The region borders the South Cameroon Plateau to the southeast, the Adamawa Plateau to the northeast and the Cameroon coastal plain to the south. Topography and geology The Western High Plateau lies along the Cameroon line, a series of volcanic swells running from the Atlantic Ocean in the southwestern part of the plateau to the Adamawa Plateau in the northeast. The region is characterised by accidented relief of massifs and mountains. The Western High Plateau features several dormant volcanoes, including the Bamboutos Mountains, Mount Oku and Mount Kupe. The plateau rises in steps from the west. To the east, it terminates in mountains that range from 1,000 metres to 2,500 met ...

Massif Du Mbam
In geology, a massif ( or ) is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term also refers to a group of mountains formed by such a structure. In mountaineering and climbing literature, a massif is frequently used to denote the main mass of an individual mountain. The massif is a smaller structural unit of the crust than a tectonic plate, and is considered the fourth-largest driving force in geomorphology. The word is taken from French (in which the word also means "massive"), where it is used to refer a large mountain mass or compact group of connected mountains forming an independent portion of a range. One of the most notable European examples of a massif is the Massif Central of the Auvergne region of France. The Face on Mars is an example of an extraterrestrial massif. Massifs may also form underwater, as with the Atlantis Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Montane Ecosystems
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] |
