Keppel Harcourt Barnard
Keppel Harcourt Barnard (31 March 1887 – 22 September 1964) was a South African zoologist and museum director. He was the only son of Harcourt George Barnard M.A. (Cantab.), a solicitor from Lambeth, and Anne Elizabeth Porter of Royston, Hertfordshire, Royston. Life and career Barnard was born in London. His first education was at a private school in Camberley from where he went to the Realgymnasium in Mannheim to improve his German. From 1905 to 1908 this unusually gifted and versatile scholar attended Christ's College, Cambridge, taking the Natural Sciences (Cambridge), Natural Sciences Tripos in Botany, Geology and Zoology. He also took the newly introduced courses in Anthropology, Ethnology and Geography. For the following three years he studied law at the Middle Temple, becoming a barrister in 1911. After a short spell as naturalist with the Marine Biological Laboratory (Plymouth), Marine Biological Laboratory in Plymouth, he joined the staff of the South African Museum ...

Freshwater Fish
Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 1.05%. These environments differ from marine conditions in many ways, especially the difference in levels of salinity. To survive fresh water, the fish need a range of physiology, physiological adaptations. 41.24% of all known species of fish are found in fresh water. This is primarily due to the rapid speciation that the scattered habitats make possible. When dealing with ponds and lakes, one might use the same basic models of speciation as when studying island biogeography. Physiology Freshwater fish differ physiologically from salt water fish in several respects. Their gills must be able to diffuse dissolved gases while keeping the salts in the body fluids inside. Their scales reduce water diffusion through the skin: freshwater fish that have lost too many scales will die. They also have well developed kidneys to reclaim salts from body flui ...

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Orange River
The Orange River (from Afrikaans/Dutch: ''Oranjerivier'') is a river in Southern Africa. It is the longest river in South Africa. With a total length of , the Orange River Basin extends from Lesotho into South Africa and Namibia to the north. It rises in the Drakensberg mountains in Lesotho, flowing westwards through South Africa to the Atlantic Ocean. The river forms part of the international borders between South Africa and Lesotho and between South Africa and Namibia, as well as several provincial borders within South Africa. Except for Upington, it does not pass through any major cities. The Orange River plays an important role in the South African economy by providing water for irrigation and hydroelectric power. The river was named the Orange River in honour of the Dutch ruling family, the House of Orange, by the Dutch explorer Robert Jacob Gordon. Other names include simply the word for river, in Khoekhoegowab orthography written as !Garib, which is rendered in Afrikaan ...

Augrabies Falls
The Augrabies Falls is a waterfall on the Orange River, the largest river in South Africa. Since 1966 the waterfall, set in a desolate and rugged milieu, is enclosed by the Augrabies Falls National Park. The falls are around in height. Some sources cite an approximate height of 480 feet; this is actually the height from the base of the canyon to the top of the walls, not that of the falls themselves. Exploration The original Khoikhoi residents named the waterfall "Ankoerebis" — "place of great noise" — from which the Trek Boers, who settled here later on, derived the name, "Augrabies". The last leader of area's native residents was Klaas Pofadder who lived on an island upstream of the falls, now known as Klaas Island. The first westerner to see the falls was the renegade Swedish mercenary Hendrik Jakob Wikar. He arrived at the falls in October 1778, after years long wanderings in the wilderness. When another traveler, George Thompson, was led to the falls by his Griqua peop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engraulicypris
''Engraulicypris'' is a genus of fish in the family (biology), family Cyprinidae endemism, endemic to Africa. In a study of Mitochondrial DNA, mitochondrial genealogy, the species formerly included in ''Mesobola'' are not Phylogenetic tree, phylogenetically separated from ''Engraulicypris'' and therefore should also be included in ''Engraulicypris''. Species There are currently 7 recognized species in this genus: * ''Engraulicypris bredoi'' Max Fernand Leon Poll, Poll, 1945 * ''Engraulicypris brevianalis'' (George Albert Boulenger, Boulenger, 1908) (river sardine) * ''Engraulicypris gariepinus'' Keppel Harcourt Barnard, Barnard, 1943 * ''Engraulicypris howesi'' Megan Amy Riddin, Riddin, Ian Roger Bills, I.
