Kibale Forest
Kibale Forest National Park is a national park in western Uganda, protecting moist evergreen rainforest. It is in size and ranges between and in elevation. Despite encompassing primarily moist evergreen forest, it contains a diverse array of landscapes.McGrew, William, ''et al''. ''Great Ape Societies''. Cambridge University Press, 1996. Print. Kibale is one of the last remaining expanses to contain both lowland and montane forests. In eastern Africa, it sustains the last significant expanse of pre-montane forest. The park was gazetted in 1932 and formally established in 1993 to protect a large area of forest previously managed as a logged forest reserve. The park forms a continuous forest with Queen Elizabeth National Park. This adjoining of the parks creates a wildlife corridor. It is an important ecotourism and safari destination, well-known for its population of habituated chimpanzees and twelve other species of primates. It is also the location of the Makerere Unive ...

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "'' Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Songbird
A songbird is a bird belonging to the suborder Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin ''oscen'', "songbird". The Passeriformes contains 5000 or so speciesEdwards, Scott V. and John Harshman. 2013. Passeriformes. Perching Birds, Passerine Birds. Version 06 February 2013 (under construction). http://tolweb.org/Passeriformes/15868/2013.02.06 in The Tree of Life Web Project, http://tolweb.org/ ccessed 2017/12/11 found all over the world, in which the vocal organ typically is developed in such a way as to produce a diverse and elaborate bird song. Songbirds form one of the two major lineages of extant perching birds (~4000 species), the other being the Tyranni (~1000 species), which are most diverse in the Neotropics and absent from many parts of the world. The Tyranni have a simpler syrinx musculature, and while their vocalizations are often just as complex and striking as thos ...

Nicatoridae
The nicators are a genus, ''Nicator'', and family, Nicatoridae, of songbirds endemic to Africa. The genus and family contain three species. Taxonomy The systematic affinities of the genus have been a long-standing mystery. The group was originally assigned to the shrikes (Laniidae). In the 1920s James Chapin noted the similarities between the nicators and both the bulbuls (Pycnonotidae) and the bushshrikes (Malaconotidae). It wasn't until 1943 that Jean Théodore Delacour placed the genus with the bulbuls. Storrs Olson argued that the genus was more closely related to the bushshrikes, as the nicators lacked the ossification of the nostril found in all other bulbuls. A number of features, including the position of the facial bristles (which are preorbital rather than rictal), their nests and the calls, make the genus unique, and DNA studies have recently suggested that the genus is best treated as a monogeneric family. Some authorities, like the Clements Checklist, treat the nicat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern Nicator
The eastern nicator (''Nicator gularis'') is a species of songbird in the family Nicatoridae. It is found in Eswatini, Kenya, Malawi, Mozambique, Somalia, South Africa, Tanzania, Zambia, and Zimbabwe. Its natural habitats are subtropical or tropical dry forests, dry savanna A savanna or savannah is a mixed woodland- grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to ..., and subtropical or tropical moist shrubland. It occurs south to around Mtunzini in northern KwaZulu-Natal, South Africa, and is regularly reported from lowland areas north through to east Africa, including inland areas along the Zambezi River. This species was formerly called the "yellow-spotted nicator" although this is no longer the case, with that name now belonging solely to the central African western nicator.

Tropical Forest
Tropical forests (a.k.a. jungle) are forested landscapes in tropical regions: ''i.e.'' land areas approximately bounded by the tropic of Cancer and Capricorn, but possibly affected by other factors such as prevailing winds. Some tropical forest types are difficult to categorise. While forests in temperate areas are readily categorised on the basis of tree canopy density, such schemes do not work well in tropical forests. There is no single scheme that defines what a forest is, in tropical regions or elsewhere.Anatoly Shvidenko, Charles Victor Barber, Reidar Persson et al. 2005 "Millennium Ecosystem Assessment." Ecosystems and human wellbeing: a framework for assessment Washington, DC: Island Press Because of these difficulties, information on the extent of tropical forests varies between sources. However, tropical forests are extensive, making up just under half the world's forests. The tropical domain has the largest proportion of the world’s forests (45 percent), followed by ...

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] |
Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...

Birds Of The African Tropical Rainforest
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 ...
