East Africa
East Africa, Eastern Africa, or East of Africa, is the eastern subregion of the African continent. In the United Nations Statistics Division scheme of geographic regions, 10-11-(16*) territories make up Eastern Africa: Due to the historical Omani Empire and colonial territories of the British East Africa Protectorate and German East Africa, the term ''East Africa'' is often (especially in the English language) used to specifically refer to the area now comprising the three countries of Kenya, Tanzania, and Uganda. However, this has never been the convention in many other languages, where the term generally had a wider, strictly geographic context and therefore typically included Djibouti, Eritrea, Ethiopia, and Somalia.Somaliland is not included in the United Nations geoscheme, as it is internationally recognized as a part of Somalia. *Tanzania, Kenya, Uganda, Rwanda, Burundi, Democratic Republic of Congo and South Sudan are members of the East African Community.

Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aberdare Range
The Aberdare Range (formerly the Sattima Range, Kikuyu: ''Nyandarua'') is a 160 km (100 mile) long mountain range of upland, north of Kenya's capital Nairobi with an average elevation of . It straddles across the counties of Nyandarua, Nyeri, Muranga, Kiambu and Laikipia. The mountain range is located in west central Kenya, northeast of Naivasha and Gilgil and lies just south of the Equator. The mountain range is called Nyandarua among the Agikuyu people in whose territory this forest and mountain range is located. The name Nyandarua comes from the Kikuyu word rwandarua meaning a drying hide, due to the distinctive fold of its silhouette. Topology The Aberdare Range forms a section of the eastern rim of the Great Rift Valley running roughly north to south. On the west, the range falls off steeply into the Kinangop Plateau and then into the Great Rift Valley. On the east, the range slopes more gently. Lake Naivasha and the distant Mau Escarpment can be seen from peaks in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Tropical East Africa
The ''Flora of Tropical East Africa'' (FTEA) is a catalogue of all 12,104 known wild plant species in Uganda, Kenya, and Tanzania. The project began in 1948 and was finally completed in September 2012. Approximately 1,500 new plant species were described, by 135 botanists from 21 countries. The ''Flora of Tropical East Africa'', a project of Royal Botanic Gardens, Kew, is the largest regional tropical Flora ever compiled. The species covered include 3-4% of the world's known plant species. When the project began in 1948, botanists thought they would be finished in fifteen years. Just in the last four years, 114 new species were described. The FTEA is an important tool for conservation of plants, wildlife, and habitat in the entire region. Approximately 2,500 of the species are endemic, or unique, to the area. The project will be used in collaboration with groups such as the IUCN Red List of Threatened Species in order to protect those species threatened with habitat loss or extinct ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Senecio
''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. Variously circumscribed taxonomically, the genus ''Senecio'' is one of the largest genera of flowering plants. Description Morphology The flower heads are normally rayed with the heads borne in branched clusters, and usually completely yellow, but green, purple, white and blue flowers are known as well. In its current circumscription, the genus contains species that are annual or perennial herbs, shrubs, small trees, aquatics or climbers. The only species which are trees are the species formerly belonging to '' Robinsonia'' occurring on the Juan Fernández Islands. Chemistry Pyrrolizidine alkaloids are found in all ''Senecio'' species. These alkaloids serve as a natural biocides to deter or even kill animals that would eat them. Livestock generally do not find them palatable. ''Senecio'' species are used as food plants by the larvae of some Lepidoptera species t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendrosenecio
''Dendrosenecio'' is a genus of flowering plants in the Asteraceae, sunflower family. It is a segregate (taxonomy), segregate of ''Senecio'', in which it formed the subgenus ''Dendrosenecio''. Its members, the giant groundsels, are native to the higher altitude zones of ten mountain groups in equatorial East Africa, where they form a conspicuous element of the flora. Description They have a giant rosette habit, with a terminal leaf rosette at the apex of a stout woody stem. When they bloom, the flowers form a large terminal inflorescence. Concomitantly, two to four lateral branches are normally initiated. As a result, old plants have the appearance of candelabras the size of telephone poles, each branch with a terminal rosette. Species ''Dendrosenecio'' varies geographically between mountain ranges, and altitudinally on a single mountain. There has been disagreement among botanists as to which populations of ''Dendrosenecio'' warrant recognition as species, and which should be r ...

Infraspecific Taxon
In botany, an infraspecific name is the scientific name for any taxon below the rank of species, i.e. an infraspecific taxon or infraspecies. (A "taxon", plural "taxa", is a group of organisms to be given a particular name.) The scientific names of botanical taxa are regulated by the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN). This specifies a 'three part name' for infraspecific taxa, plus a 'connecting term' to indicate the rank of the name., Art. 24 An example of such a name is ''Astrophytum myriostigma'' subvar. ''glabrum'', the name of a subvariety of the species '' Astrophytum myriostigma'' (bishop's hat cactus). Names below the rank of species of cultivated kinds of plants and of animals are regulated by different codes of nomenclature and are formed somewhat differently. Construction of infraspecific names Article 24 of the ICN describes how infraspecific names are constructed. The order of the three parts of an infraspecific name is: :genus ...
