George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels (1834–1969), Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''National Museum of Natural History (France), Muséum national d'Histoire naturelle'' in Paris and the Natural History Museum, London, British Museum in London.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Labeobarbus
''Labeobarbus'' is a mid-sized ray-finned fish genus in the family Cyprinidae. Its species are widely distributed throughout eastern Africa and especially southern Africa, but also in Lake Tana in Ethiopia. A common name, in particular for the southern species, is yellowfish. The scientific name refers to the fact that these large barbs recall the fairly closely related "carps" in the genus '' Labeo'' in size and shape. As far as can be told, all ''Labeobarbus'' species are hexaploid.de Graaf ''et al.'' (2007), IUCN (2009) One species, '' L. microbarbis'' from Rwanda, is known to have gone extinct in recent times. Systematics Like many other "barbs", it was long included in ''Barbus''. It appears to be a fairly close relative of the typical barbels and relatives – the genus ''Barbus'' proper – but closer still to the large Near Eastern species nowadays separated in '' Carasobarbus''. ''Barbus'' has been split to account for the improved phylogenetic knowledge which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Mweru
Lake Mweru (also spelled ''Mwelu'', ''Mwero'') (, ) is a freshwater lake on the longest arm of Africa's second-longest river, the Congo. Located on the border between Zambia and Democratic Republic of the Congo, it makes up of the total length of the Congo, lying between its Luapula River (upstream) and Luvua River (downstream) segments.Google Earth accessed 29 March 2007. When in flood Lake Bangweulu and its swamps may temporarily have a larger area, but not a larger volume. Mweru means 'lake' in a number of Bantu languages, so it is often referred to as just 'Mweru'.The '' Northern Rhodesia Journal'' online at NZRAM.org: J B W Anderson: "Kilwa Island and the Luapula." Vol II, No. 3 pp87–88 (1954) Physical geography Mweru is mainly fed by the Luapula River, which comes in through swamps from the south, and the Kalungwishi River from the east. At its north end the lake is drained by the Luvua River, which flows in a northwesterly direction to join the Lualaba River and th ...

Luapula River
The Luapula River is a north-flowing river of central Africa, within the Congo River watershed. It rises in the wetlands of Lake Bangweulu (Zambia), which are fed by the Chambeshi River. The Luapula flows west then north, marking the border between Zambia and the Democratic Republic of the Congo before emptying into Lake Mweru. The river gives its name to Zambia's Luapula Province.Terracarta/International Travel Maps, Vancouver Canada: "Zambia, 2nd edition", 2000 Source and upper Luapula The Luapula drains Lake Bangweulu and its swamps into which flows the Chambeshi River, the source of the Congo. There is no single clear channel connecting the two rivers and the lake, but a mass of shifting channels, lagoons and swamps, as the explorer David Livingstone found to his cost. (He died exploring the area, and one of his last acts was to question Chief Chitambo about the course of the Luapula.)Blaikie, William Garden (1880): ''The Personal Life Of David Livingstone''Project Gutenb ...

Democratic Republic Of The Congo
The Democratic Republic of the Congo (DRC), also known as the DR Congo, Congo-Kinshasa, or simply the Congo (the last ambiguously also referring to the neighbouring Republic of the Congo), is a country in Central Africa. By land area, it is the List of African countries by area, second-largest country in Africa and the List of countries and dependencies by area, 11th-largest in the world. With a population of around 112 million, the DR Congo is the most populous nominally List of countries and territories where French is an official language, Francophone country in the world. Belgian French, French is the official and most widely spoken language, though there are Languages of the Democratic Republic of the Congo, over 200 indigenous languages.

Zambia
Zambia, officially the Republic of Zambia, is a landlocked country at the crossroads of Central Africa, Central, Southern Africa, Southern and East Africa. It is typically referred to being in South-Central Africa or Southern Africa. It is bordered to the north by the Democratic Republic of the Congo, Tanzania to the north-east, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, Namibia to the southwest, and Angola to the west. The capital city of Zambia is Lusaka, located in the south-central part of Zambia. The population is concentrated mainly around Lusaka in the south and the Copperbelt Province to the north, the core economic hubs of the country. Originally inhabited by Khoisan peoples, the region was affected by the Bantu expansion of the thirteenth century. Following European colonization of Africa, European colonisers in the 18th century, the British colonised the region into the British protectorates of Barotziland–North-Western Rho ...

Taxa Named By George Albert Boulenger
In biology, a taxon (back-formation from ''taxonomy''; : 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
