Corubal River
The Corubal, also known as the Rio Corubal or Tomine, is a river of West Africa, a major tributary of the Geba River. For a short distance, it forms the international border between Guinea and Guinea-Bissau. It has a length of approximately . History During the Portuguese Colonial War in February 1969, the Portuguese army, while retreating from territories in the Madina do Boe sector, lost 47 soldiers to drowning when their overloaded raft tipped to a side while crossing the Corubal. The incident became known as the Cheche Disaster. Treaty A protocol agreement called the "Corubal River Agreement" was signed on 21 October 1978 at Conakry by the Republic of Guinea and the Republic of Guinea Bissau to develop and manage the Kaliba-Koribal River; the Corubal River is also called the Kaliba. The "Organisation pour la Mise en Valeur du Fleuve Gambie" (OMVG) also known as "The Gambia River Basin Development Organization" was also agreed to be established to study and develop manageme ...

River
A river is a natural stream of fresh water that flows on land or inside Subterranean river, caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the Runoff (hydrology), runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their Bank (geography), banks and flood the surrounding area, spreading nutrients to the surrounding area.

Bissau
Bissau () is the Capital (political), capital and largest city of Guinea-Bissau. it had a population of 492,004. Bissau is located on the Geba River estuary, off the Atlantic Ocean, and is Guinea-Bissau's largest city, major port, its administrative and military center. Etymology The term Bissau may have come from the name of a clan N'nssassun, in its plural form Bôssassun. Intchassu (Bôssassu) was the name given to the nephew of King Mecau—the first sovereign of the island of Bissau—son of his sister Pungenhum. Bôssassu formed a clan of the Papel peoples. History From well before the arrival of Europeans to the early 20th century, the island of Bissau was governed as a kingdom inhabited by the Papel people. According to oral tradition, the kingdom was founded by Mecau, the son of the king of Quinara (Guinala), who moved to the area with his pregnant sister, six wives, and subjects of his father's kingdom. The kingdom was composed of seven clans, descended from the sist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodland
A woodland () is, in the broad sense, land covered with woody plants (trees and shrubs), or in a narrow sense, synonymous with wood (or in the U.S., the '' plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American and Australian English explained below). Some savannas may also be woodlands, such as ''savanna woodland'', where trees and shrubs form a light canopy. Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana ha ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and 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 support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoel Cláudio da ...

Anopheles
''Anopheles'' () is a genus of mosquito first described by the German entomologist Johann Wilhelm Meigen, J. W. Meigen in 1818, and are known as nail mosquitoes and marsh mosquitoes. Many such mosquitoes are Disease vector, vectors of the parasite ''Plasmodium'', a genus of protozoans that cause malaria in Plasmodium species infecting birds, birds, Plasmodium species infecting reptiles, reptiles, and Plasmodium species infecting mammals other than primates, mammals, including humans. The ''Anopheles gambiae'' mosquito is the best-known species of marsh mosquito that transmits the ''Plasmodium falciparum'', which is a malarial Parasitism, parasite deadly to human beings; no other mosquito genus is a vector of human malaria. The genus ''Anopheles'' diverged from other mosquitoes approximately (myr, mya), and, like other mosquitoes, the eggs, larvae, and pupae are Aquatic animal, aquatic. The ''Anopheles'' larva has no respiratory siphon through which to breathe, so it breathes an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marshy
In ecology, a marsh is a wetland that is dominated by herbaceous plants rather than by woody plants.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p More in general, the word can be used for any low-lying and seasonally waterlogged terrain. In Europe and in agricultural literature low-lying meadows that require draining and embanked polderlands are also referred to as marshes or marshland. Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove
A mangrove is a shrub or tree that grows mainly in coastal saline water, saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal rivers. They have particular adaptations to take in extra oxygen and remove salt, allowing them to tolerate conditions that kill most plants. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse due to convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Kōya
is a large temple settlement in Wakayama Prefecture, Japan to the south of Osaka. In the strictest sense, ''Mount Kōya'' is the mountain name ( sangō) of Kongōbu-ji Temple, the ecclesiastical headquarters of the Kōyasan sect of Shingon Buddhism. History First settled in 819 by the monk Kūkai, Mount Kōya is primarily known as the world headquarters of the Kōyasan Shingon sect of Japanese Buddhism. Located on an 800-meter-high plain amid eight peaks of the mountain, which was the reason this location was selected, in that the terrain is supposed to resemble a lotus plant, the original monastery has grown into the town of Kōya. Koya features a university dedicated to religious studies and 120 sub-temples, many of which offer lodging to pilgrims. Mount Kōya is also a common starting point to the associated with Kūkai. Sites The mountain is home to the following famous sites: * , the head temple of the Kōyasan Shingon Buddhism. Located roughly in the middle of ...

Kola Nut
The kola nut ( Yoruba: ''obi'', Dagbani: ''guli'', Hausa: goro, Igbo: ''ọjị'', Sängö: ''gôro,'' Swahili: ''mukezu'') is the seed of certain species of plant of the genus ''Cola'', placed formerly in the cocoa family Sterculiaceae and now usually subsumed in the mallow family Malvaceae (as subfamily Sterculioideae). These cola species are trees native to the tropical rainforests of Africa. Their caffeine-containing seeds are used as flavoring ingredients in various carbonated soft drinks, from which the name ''cola'' originates. Description About across, the kola nut is a nut of evergreen trees of the genus ''Cola'', primarily of the species ''Cola acuminata'' and '' Cola nitida''. ''Cola acuminata'', an evergreen tree about 20 meters in height, has long, ovoid leaves pointed at both the ends with a leathery texture. The trees have cream-white flowers with purplish-brown striations, and star-shaped fruit consisting of usually 5 follicles. Inside each follicle, ab ...
