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

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kwilu River
The Kwilu River is a major river in the Kwilu Province formerly known as Bandundu province in the Democratic Republic of the Congo (DRC) to the city of Bandundu, where it joins the Kwango River just before this stream enters the Kasai River. In the DRC the river flows past the towns of Gungu, Kikwit, Bulungu, Bagata, Rutherfordia and Bandundu. Lusanga, formerly Leverville, lies at the location where the Kwenge River joins the Kwilu, between Kikwit and Bulungu. Characteristics It is a meandering river. Near its mouth it is 950 meter wide. The bed material is sand. The river is about long. In the wet season the flooded area covers . The headwaters of the river rise at elevations between and in the Angolan highlands.

Lake Tumba
Lake Tumba (or Ntomba) is a shallow lake in northwestern part of the Democratic Republic of the Congo, in the Bikoro Territory of the Province of Équateur. The lake covers about depending on the season, connected via the Irebu channel with the Congo River. Water may flow into or out of the lake through this channel depending on the floods. Lake Tumba has 114 species of fish and supports important fisheries. The lake lies at the center of the Tumba-Ngiri-Maindombe area, designated a Wetland of International Importance by the Ramsar Convention in 2008. Lake Tumba was explored in 1883 by Henry Morton Stanley. The swamp forest surrounding the lake is inhabited by the Mongo people, who in this area are divided into two castes: the ''Oto'', who farm, and the ''Twa'', Pygmies In anthropology, pygmy peoples are ethnic groups whose average height is unusually short.

Fish Of Africa
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 placodermi, 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 arthropo ...

Taxa Named By Jacobus Johannes Hoedeman
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 intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
