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 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 ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

Dja River
The Dja River (also known as the Ngoko River) is a stream in west-central Africa. It forms part of Cameroon–Republic of Congo border and has a course of roughly . Rising southeast of the southeastern Cameroon town of Abong-Mbang, the Dja Faunal Reserve, which was named a UNESCO World Heritage Site in 1987, lies along the banks of its upper course. It protects one of the largest tracts of tropical rainforest in Africa. Forming its natural boundary, and almost completely encircling the reserve (except to the south-west), cliffs run along the course of the river in the south part of the reserve for 60 km and are associated with a section of the river which is broken by rapids and waterfalls. Following its course in the reserve, the Dja flows approximately southeast past Moloundou, below which small boats can navigate. At Ouesso, in the Republic of Congo, it empties into the Sangha River. Every year, poachers travel up the Dja for central Nki National Park, where elephant iv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sangha
Sangha is a Sanskrit word used in many Indian languages, including Pali meaning "association", "assembly", "company" or "community"; Sangha is often used as a surname across these languages. It was historically used in a political context to denote a governing assembly in a republic or a kingdom, and has long been used by religious associations including the Buddhists, Jains and Sikhs. Given this history, some Buddhists have said the tradition of the ''sangha'' represents humanity's oldest surviving democratic institution. In Buddhism, ''sangha'' refers to the monastic community of ''bhikkhu'' (monks) and '' bhikkhuni'' (nuns). These communities are traditionally referred to as the ''bhikkhu-sangha'' or ''bhikkhuni-sangha''. As a separate category, those who have attained any of the four stages of enlightenment, whether or not they are members of the monastic community, are referred to as the ''āryasaṅgha'' ("noble Sangha").

Cameroon
Cameroon (; french: Cameroun, ff, Kamerun), officially the Republic of Cameroon (french: République du Cameroun, links=no), is a country in west-central Africa.

Freshwater Fish Of Africa
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water i ...

Taxa Named By George Albert Boulenger
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] |
