Ad Konings
Adrianus Franciscus Johannes Marinus Maria "Ad" Konings (born 11 January 1956 in Roosendaal, Netherlands) is an ichthyologist originally trained in medicine and biology. Konings is best known for his research on African rift lake cichlids. After studies in Amsterdam, he has spent most of his life in Rotterdam. Early life Konings started keeping cichlids when he was 14 years old in 1970. Soon he was breeding rare African cichlids and working as an assistant to the largest tropical fish dealer in the Netherlands. Academic studies and early career From 1974-1980 he studied medical biology at the University of Amsterdam and was awarded his Ph.D. in 1980. He chose this field despite his love of ichthyology due to a fear that if he chose the latter field he would be unemployable. From 1980-1986. he did research on lysosomal enzymes at the Erasmus University in Rotterdam. Most of this was DNA-related work (molecular biology). In 1986, Konings moved to St. Leon-Rot, Germany (n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichlid
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquariu ...

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] |
Lake Malawi
Lake Malawi, also known as Lake Nyasa in Tanzania and Lago Niassa in Mozambique, is an African Great Lake and the southernmost lake in the East African Rift system, located between Malawi, Mozambique and Tanzania. It is the fifth largest fresh water lake in the world by volume, the ninth largest lake in the world by area—and the third largest and second deepest lake in Africa. Lake Malawi is home to more species of fish than any other lake in the world, including at least 700 species of cichlids.Turner, Seehausen, Knight, Allender, and Robinson (2001). "How many species of cichlid fishes are there in African lakes?" ''Molecular Ecology'' 10: 793–806. The Mozambique portion of the lake was officially declared a reserve by the Government of Mozambique on June 10, 2011,WWF (10 June 2011)"Mozambique’s Lake Niassa declared reserve and Ramsar site"Retrieved 17 July 2014. while in Malawi a portion of the lake is included in Lake Malawi National Park.

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.

Northern Rhodesia
Northern Rhodesia was a British protectorate in southern Africa, south central Africa, now the independent country of Zambia. It was formed in 1911 by Amalgamation (politics), amalgamating the two earlier protectorates of Barotziland-North-Western Rhodesia and North-Eastern Rhodesia.''Commonwealth and Colonial Law'' by Kenneth Roberts-Wray, London, Stevens, 1966. P. 753 It was initially administered, as were the two earlier protectorates, by the British South Africa Company (BSAC), a chartered company, on behalf of the British Government. From 1924, it was administered by the British Government as a protectorate, under similar conditions to other British-administered protectorates, and the special provisions required when it was administered by BSAC were terminated.Northern Rhodesia Order in Council, 1924, S.R.O. 1924 No. 324, S.RO. & S.I.

Nyasaland
Nyasaland () was a British protectorate located in Africa that was established in 1907 when the former British Central Africa Protectorate changed its name. Between 1953 and 1963, Nyasaland was part of the Federation of Rhodesia and Nyasaland. After the Federation was dissolved, Nyasaland became independent from Britain on 6 July 1964 and was renamed Malawi. Nyasaland's history was marked by the massive loss of African communal lands in the early colonial period. In January 1915, the Reverend John Chilembwe staged an attempt at rebellion in protest at discrimination against Africans. Colonial authorities reassessed some of their policies. From the 1930s, a growing class of educated African elite, many educated in the United Kingdom, became increasingly politically active and vocal about gaining independence. They established associations and, after 1944, the Nyasaland African Congress (NAC). When Nyasaland was forced in 1953 into a Federation with Southern and Northern Rho ...

Sciaenochromis
''Sciaenochromis'' is a genus of haplochromine cichlids endemic to Lake Malawi in East Africa. The species are popular in the aquarium hobby, most notably '' S. fryeri''. Only males possess the impressive, electric blue coloration, while females are dull grey, and generally similar to the females of ''Aulonocara'' species. All ''Sciaenochromis'' are piscivores (fish-eaters) and prey mainly upon the fry of mbuna and other haplochromine cichlids. Species There are currently four recognized species in this genus: In the aquarium Like all cichlids from Lake Malawi, they are best maintained in hard, alkaline water. ''Sciaenochromis'' are best kept in tanks with volumes greater than 210 L (55 gal). This is an aggressive fish, and the minimum tank size of 210 litres is only acceptable with a trio of 1 male and 2 females. When more than one male is kept, experts recommend a minimum tank size of being the minimum. Males can also display aggression towards similarly-coloured fish o ...

Fish Of Malawi
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Taxa Named By Ad Konings
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
