Ethiopian Montane Forests
The Ethiopian montane forests is a tropical moist broadleaf forest ecoregion in eastern Africa. It covers the middle elevations of the Ethiopian Highlands in Ethiopia and extends into neighboring Eritrea, Sudan, Djibouti, and Somaliland. The ecoregion includes distinctive Afromontane forests, woodlands, grasslands, and shrublands. The ecoregion's biodiversity is threatened by deforestation, conversion to agriculture, and overgrazing. Geography The Ethiopian montane forests lie between 1,100 and 1,800 meters elevation. They extend throughout the middle elevations of the Ethiopian Highlands, which are mostly in Ethiopia and reach into neighboring Eritrea and Somaliland. The ecoregion also includes several outlying mountains, including Jebel Elba, Jebel Hadai Aweb, and Jebel Ower in eastern Sudan, and the Goda and Mabla mountains in Djibouti. The montane forests are bounded at lower elevations by tropical grasslands and savannas on the west and southwest, and deserts and dry shrubl ...

Afrotropical Realm
The Afrotropical realm is one of Earth's eight biogeographic realms. It includes Africa south of the Sahara Desert, the majority of the Arabian Peninsula, the island of Madagascar, southern Iran and extreme southwestern Pakistan, and the islands of the western Indian Ocean. It was formerly known as the Ethiopian Zone or Ethiopian Region. Major ecological regions Most of the Afrotropic, with the exception of Africa's southern tip, has a tropical climate. A broad belt of deserts, including the Atlantic and Sahara deserts of northern Africa and the Arabian Desert of the Arabian Peninsula, separate the Afrotropic from the Palearctic realm, which includes northern Africa and temperate Eurasia. Sahel and Sudan South of the Sahara, two belts of tropical grassland and savanna run east and west across the continent, from the Atlantic Ocean to the Ethiopian Highlands. Immediately south of the Sahara lies the Sahel belt, a transitional zone of semi-arid short grassland and vachellia sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ochna Holstii
''Ochna''Linnaeus C (1753) ''Sp. Pl.'' 1: 513. is a genus comprising 86 species of evergreen trees, shrubs and shrublets belonging to the flowering plant family ''Ochnaceae''. These species are native to tropical woodlands of Africa, the Mascarenes and Asia. Species of this genus are usually called ochnas, bird's-eye bushes or Mickey-mouse plants, a name derived from the shape of the drupelet fruit. The name of this genus comes from the Greek word ''Ochne'', used by Homer and meaning ''wild pear'', as the leaves are similar in appearance. Some species, including ''Ochna integerrima'' (yellow ''Mai'' flower) and '' O. serrulata'' (bird's eye plant), are cultivated as decorative plants. Distribution Species of this genus are found in the Old World Tropics, especially in Africa, Madagascar, the Mascarene Islands and Asia. Selected species *''Ochna afzelii'' *''Ochna andamanica'' *''Ochna angustata'' *''Ochna arborea'' *''Ochna awrrulata'' *''Ochna barbosae'' – sand plane, ...

Macaranga Capensis
''Macaranga'' is a large genus of Old World tropical trees of the family Euphorbiaceae and the only genus in the subtribe Macaranginae (tribe Acalypheae). Native to Africa, Australasia, Asia and various islands of the Indian and Pacific Oceans, the genus comprises over 300 different species. It was first described as a genus in 1806, based on specimens collected on the Island of Mauritius. ''Macaranga'' is noted for being recolonizers. ''Macaranga'' species are used as food plants by the larvae of some Lepidoptera species including ''Endoclita malabaricus''. ''Macaranga'' species often form symbioses with ant ( Formicidae) species (particularly ''Crematogaster'' ants of the subgenus '' Decacrema'') because they have hollow stems that can serve as nesting space and occasionally provide nectar. The trees benefit because the ants attack herbivorous insects and either drive them away or feed on them. Use * Macaranga gum, a crimson resin, is obtained from '' Macaranga indica''. * ' ...

Acacia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boswellia
''Boswellia'' is a genus of trees in the order Sapindales, known for its fragrant resin. The biblical incense frankincense is an extract from the resin of the tree ''Boswellia sacra'', and is now produced also from '' B. frereana''. Frankincense The four main species of ''Boswellia'', ''B. sacra'' (synonyms ''B. carteri'' and ''B. bhaw-dajiana''), ''B. frereana'', ''B. papyrifera'', and ''B. serrata'', produce true frankincense, and each type of resin is available in various grades. The grades depend on the time of harvesting, and the resin is hand sorted for quality. Description ''Boswellia'' species are moderate-sized flowering plants, including both trees and shrubs, and are native to tropical regions of Africa and Asia. The distributions of the species are primarily associated with the tropics.Weeks, A., Daly, D.C. and B.B. Simpson. 2005.

Orographic Precipitation
Orography is the study of the topographic relief of mountains, and can more broadly include hills, and any part of a region's elevated terrain. Orography (also known as ''oreography'', ''orology'' or ''oreology'') falls within the broader discipline of geomorphology. The term orography comes from the Greek: , hill, , to write. Uses Mountain ranges and elevated land masses have a major impact on global climate. For instance, the elevated areas of East Africa substantially determine the strength of the Indian monsoon.Srinivasan, J., Nanjundiah, Ravi S. and Chakraborty, Arindam (2005Impact of Orography on the Simulation of Monsoon Climate in a General Circulation Model''Indian Institute of Science'' In scientific models, such as general circulation models, orography defines the lower boundary of the model over land. When a river's tributaries or settlements by the river are listed in 'orographic sequence', they are in order from the highest (nearest the source of the river) to the l ...
