Rwenzori Apalis
The Rwenzori apalis or collared apalis (''Oreolais ruwenzorii'') is a species of bird in the family Cisticolidae. It is found in Burundi, Democratic Republic of the Congo, Rwanda, and Uganda. Its natural habitat is subtropical or tropical moist montane forest. The Rwenzori apalis was formerly placed in the genus ''Apalis'' but was moved to the new genus ''Oreolais'' when ''Apalis'' was shown to be polyphyletic.

Frederick John Jackson
Sir Frederick John Jackson, (17 February 1860 – 3 February 1929) was an English administrator, explorer and ornithologist. Early years Jackson was born at Oran Hall, near Catterick, North Yorkshire in 1860. He attended Shrewsbury School and then Jesus College, Cambridge. In 1884 he went to Africa on a shooting trip, joining J. G. Haggard, the British consul at Lamu. On this trip he explored the coast of what is now Kenya, the Tana River and Mount Kilimanjaro. As well as shooting big game, he collected birds and butterflies. Soon after the 1886 treaty was signed to delimit the German and British spheres of influence in East Africa he joined the Imperial British East Africa Company (IBEAC). Administrator In 1889 Jackson led an IBEAC expedition that included his friend and fellow explorer Arthur Neumann in the party designed to open up the regions between Mombasa and Lake Victoria, which was largely unknown to Europeans at that time, and if possible to obtain news of ...

Bird
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. B ...

Cisticolidae
The family Cisticolidae is a group of about 160 warblers, small passerine birds found mainly in warmer southern regions of the Old World. They were formerly included within the Old World warbler family Sylviidae. This family probably originated in Africa, which has the majority of species, but there are representatives of the family across tropical Asia into Australasia, and one species, the zitting cisticola, breeds in Europe. These are generally very small birds of drab brown or grey appearance found in open country such as grassland or scrub. They are often difficult to see and many species are similar in appearance, so the song is often the best identification guide. These are insectivorous birds which nest low in vegetation. Taxonomy The family was introduced (as Cisticolinae) by the Swedish zoologist Carl Jakob Sundevall in 1872. Many taxonomists place the red-winged prinia and the red-fronted prinia in the genus ''Prinia'' rather than in their own monotypic genera. Suppo ...

Rwanda
Rwanda (; rw, u Rwanda ), officially the Republic of Rwanda, is a landlocked country in the Great Rift Valley of Central Africa, where the African Great Lakes region and Southeast Africa converge. Located a few degrees south of the Equator, Rwanda is bordered by Uganda, Tanzania, Burundi, and the Democratic Republic of the Congo. It is highly elevated, giving it the soubriquet "land of a thousand hills", with its geography dominated by mountains in the west and savanna to the southeast, with numerous lakes throughout the country. The climate is temperate to subtropical, with two rainy seasons and two dry seasons each year. Rwanda has a population of over 12.6 million living on of land, and is the most densely populated mainland African country; among countries larger than 10,000 km2, it is the fifth most densely populated country in the world. One million people live in the Capital city, capital and largest city Kigali. Hunter-gatherers settled the territory in the St ...

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] |
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] |
Apalis
The apalises are small passerine birds belonging to the genus ''Apalis'', in the family Cisticolidae. They are found in forest, woodlands and scrub across most parts of sub-Saharan Africa. They are slender birds with long tails and have a slender bill for catching insects. They are typically brown, grey or green above and several species have brightly coloured underparts. Males and females are usually similar in appearance but the males are sometimes brighter. The genus was erected by the English naturalist William John Swainson in 1833. The type species is the bar-throated apalis. The name ''Apalis'' is from the Ancient Greek ''hapalos'' meaning "delicate" or "gentle". Apalises were traditionally classified in the Old World warbler family Sylviidae but are now commonly placed, together with several other groups of mainly African warblers, in a separate family Cisticolidae. There are about 24 species of apalis; the exact number varies according to differing authorities. The Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...
