Pseudocrenilabrinae
The Pseudocrenilabrinae are a subfamily in the cichlid family of fishes to which, according to a study from 2004, includes all the Middle Eastern and African cichlids with the exception of the unusual '' Heterochromis multidens'' and the Malagasy species. This subfamily includes more than 1,100 species. Previous authors recognized additional African subfamilies, e.g. the Tilapiinae of Hoedeman (1947), Tylochrominae of Poll (1986), or Boulengerochrominae of Tawil (2001). To this subfamily belong the cichlids from the African Great Lakes, such as the utaka and mbuna in Lake Malawi, and various species from Lake Victoria and Lake Tanganyika. The Pseudocrenilabrinae tribes Haplochromini and Oreochromini are widespread in Africa and also found in the Middle East, while Chromidotilapiini, Hemichromini and Tylochromini are primarily West and Central African. The remaining tribes are largely or entirely restricted to Lake Tanganyika. Systematics Apart from the tribes mentioned in th ...

Anomalochromis Thomasi
''Anomalochromis'' is a genus of fish in the family Cichlidae, containing the single species ''Anomalochromis thomasi'', the African butterfly cichlid. It is a small cichlid growing to a length of . The natural habitat of ''A. thomasi'' is Sierra Leone, Liberia and Guinea, mainly in smaller streams. The fish are typically found in slightly acidic, oxygen rich water with other west African cichlid genera such as '' Hemichromis'' and ''Pelvicachromis''. This species is found in forest streams, shaded by dense overhanging vegetation where the water is heavily stained with tannins from decaying organic matter and is coloured like tea. In these streams the temperature of the water can approach in the dry season. It can also occur in streams in forest edge habitats. Under stress or when disturbed ''A. thomasi'' can bury itself in the mud, occasionally down to . They form pairs which spawn into the substrate. These pairs are territorial, the female selects a laying site on a leaf or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jewel Cichlid
''Hemichromis'' is a genus of fishes from the cichlid family, known in the aquarium trade as jewel cichlids. Jewel cichlids are native to Africa. Within West Africa, ''Hemichromis'' species are found in creeks, streams, rivers and lakes with a variety of water qualities including brackish water lagoons. Maximum size reported for the different species of ''Hemichromis'' ranges from in total length. Maximum sizes in aquaria tend to be slightly smaller than in the wild. Many ''Hemichromis'' species are brightly coloured, though brighter body colouration is generally evident during breeding. Sexual dimorphism is limited, though male jewel cichlids are typically more brightly coloured and in some species have more pointed anal, ventral and dorsal fins. In some species, such as ''Hemichromis cristatus'', the females can have coloring as bright as the males. Like most cichlids, jewel cichlids have highly developed brood care. ''Hemichromis'' species typically form monogamous breeding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacobus Johannes Hoedeman
A Jacobus is an English gold coin of the reign of James I, worth 25 shillings. The name of the coin comes from the Latin inscription surrounding the King's head on the obverse of the coin, IACOBUS D G MAG BRIT FRA ET HI REX ("James, by the grace of God, of Britain, France and Ireland King"). Isaac Newton refers to the coin in a letter to John Locke: '' The Jacobus piece coin'd for 20 shillings is the : part of a pound Troy, and a Carolus 20s piece is of the same weight. But a broad Jacobus (as I find by weighing some of them) is the 38th part of a pound Troy.'' dated September 19, 1698, to John Locke, concerning the weight and fineness of various coins. These correspond to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Humphry Greenwood
Peter Humphry Greenwood Fellow of the Royal Society, FRS FIBiol (21 April 1927 – 3 March 1995) was an English ichthyologist. Humphry married fellow student Marjorie George (1924 – 2006) in 1950. He was elected a Fellow of the Royal Society in 1985. He was known for his work on the species flocks of cichlids in the African Great Lakes, and for studies of the phylogeny and systematics of teleosts. Tribute The cichlid fish ''Diplotaxodon greenwoodi'' is named for him. Also ''Brachyaetoides greenwoodi'' Bonde, 2008 is named for him. As is ''Enteromius greenwoodi'' (Max Poll, Poll 1967).

Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 in Koldenbüttel – 20 April 1883) was a German natural history, naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Natural History Museum, Berlin, Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he g ...

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
