Monteiro's Bush-shrike
Monteiro's bushshrike (''Malaconotus monteiri'') is a species of bird in the bush-shrike family ( Malaconotidae). Taxonomy Two described subspecies: nominate ''Malaconotus m. monteiri'' (Shape, 1870) described from Angola, and ''M. m. perspicillatus'' (Reichenow, 1894) known from only a single specimen in Cameroon. Subspecies ''perspicillatus'' differs from the nominate in having a larger bill and paler undersides. Presumed to be closely related to other ''Malaconotus'', and has been considered conspecific with both gray-headed bushshrike ''M. blanchoti'' and fiery-breasted bushshrike ''M. cruentus'' in the past. Cameroonian ''M. m. perspicillatus'' has also been theorized to be a color morph of the green-breasted bushshrike. The specific phylogenetic relationships of ''M. monteiri'' are, as of yet, unknown. Distribution and habitat It is found in Angola and Cameroon, with a historical record from the Albertine Rift of eastern Democratic Republic of the Congo and a lost speci ...

Joseph Smit
Joseph Smit (18 July 1836 – 4 November 1929) was a Dutch zoological illustrator. L.B. Holthuis, Leiden, (1958, 1995) ''Rijksmuseum van Natuurlijke Historie, 1820 - 1958''. page 47reprint manuscript, PDF Background Smit was born in Lisse. He received his first commission from Hermann Schlegel at the Leiden Museum to work on the lithographs for a book on the birds of the Dutch East Indies. In 1866 he was invited to Britain by Philip Sclater to do the lithography for Sclater's ''Exotic Ornithology''; he prepared a hundred images for the book. He also did the lithography for his friend Joseph Wolf's ''Zoological Sketches'', as well as Daniel Giraud Elliot's monographs on the Phasianidae and Paradisaeidae. Beginning in the 1870s, he worked on the ''Catalogue of the Birds in the British Museum'' (1874–1898, edited by Richard Bowdler Sharpe), and later on Lord Lilford's ''Coloured Figures of the Birds of the British Islands''. Smit contributed illustrations to John Gould's boo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albertine Rift
The Albertine Rift is the western branch of the East African Rift, covering parts of Uganda, the Democratic Republic of the Congo (DRC), Rwanda, Burundi and Tanzania. It extends from the northern end of Lake Albert to the southern end of Lake Tanganyika. The geographical term includes the valley and the surrounding mountains. Geology The Albertine Rift and the mountains are the result of tectonic movements that are gradually splitting the Somali Plate away from the rest of the African continent. The mountains surrounding the rift are composed of uplifted Pre-Cambrian basement rocks, overlaid in parts by recent volcanic rocks. Lakes and rivers The northern part of the rift is crossed by two large mountain ranges, the Rwenzori Mountains between Lake Albert and Lake Rutanzige (formerly Lake Edward) and the Virunga Mountains between Lake Rutanzige and Lake Kivu. The Virungas form a barrier between the Nile Basin to the north and east and the Congo Basin to the west and south. Lak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Central Africa
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. Birds ...

Malaconotus
''Malaconotus'' is a genus of passerine birds in the bush-shrike family Malaconotidae, which is endemic to sub-Saharan Africa. Their Greek generic name suggests fluffy back and rump feathers. Description All are large-bodied with robust legs and feet, and formidable shrike-like bills. As in other Malacotini, the upper mandible (maxilla) has a subterminal tooth, opposing a notch on the lower mandible. Both nasal and rictal bristles are present, and they are unique in their family in having syndactyl feet (3rd and 4th digits fused). They have 10 primaries and 12 rectrices like others of their family. The sexes are similar in appearance, but have dissimilar calls. Habits They form monogamous pairs that live fairly sedentary in woodlands or tropical forest. They are very vocal, but their duetting is poorly developed compared to the related genus ''Telophorus''. Their displays include bill-snapping, a habit shared with helmetshrikes (and some vangas of Madagascar), which however di ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Bakossi Mountains
The Bakossi Mountains are a mountain range that forms part of the Cameroon line of active and extinct volcanoes in western Cameroon, covering about . The mountains lie in the regions of Littoral and the Southwest. The highest peak in this range is Mount Kupe at . They contain a large area of cloud forest, and have considerable ecological interest. The mountains are home to the Bakossi people. The climate is tropical, with rainfall throughout the year. The drier season lasts from November to March, with cold nights and hot days. The rainy season starts in April and peaks between late August and the end of October. The soil is fertile, supporting coffee and cocoa as cash crops. The mountains hold the Bakossi Forest Reserve, a reserve created in 1956. In 2000, the main section of the reserve was designated a protection forest. All logging was banned and Kupe became a "strict nature reserve". The local Bakossi people participated in delineating the boundaries. The Forest Reserve in ...

Montane Forest
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] |
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] |

Kakamega Forest
Kakamega Forest is a tropical rainforest situated in the Kakamega County, Kakamega and Nandi_County, Nandi County of Kenya, northwest of the capital Nairobi, and near to the border with Uganda. It is Kenya's only tropical rainforest and is said to be Kenya's last remnant of the ancient Guineo-Congolian region, Guineo-Congolian rainforest that once spanned the continent. Geography The forest lies on undulating terrain, mostly between 1500 and 1600 meters elevation. It is in the watershed of the Isiukhu and Yala rivers, which flow through the forest before emptying into Lake Victoria. The forest including reserves encloses about 238 square kilometers, a little less than half of which currently remains as indigenous forest. In the north of the forest is the Kakamega National Reserve, given national forest reserve status in 1985. Just to the north is the Kisere Forest Reserve. Throughout the forest are a series of grassy glades, ranging in size from about 1 to 50, with a few larger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cameroon
Cameroon (; french: Cameroun, ff, Kamerun), officially the Republic of Cameroon (french: République du Cameroun, links=no), is a country in west-central Africa. It is bordered by Nigeria to the west and north; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon and the Republic of the Congo to the south. Its coastline lies on the Bight of Biafra, part of the Gulf of Guinea and the Atlantic Ocean. Due to its strategic position at the crossroads between West Africa and Central Africa, it has been categorized as being in both camps. Its nearly 27 million people speak 250 native languages. Early inhabitants of the territory included the Sao civilisation around Lake Chad, and the Baka hunter-gatherers in the southeastern rainforest. Portuguese explorers reached the coast in the 15th century and named the area ''Rio dos Camarões'' (''Shrimp River''), which became ''Cameroon'' in English.
