Houting
''Coregonus lavaretus'' is a species of freshwater whitefish, in the family Salmonidae. It is the type species of its genus ''Coregonus''. There are widely different concepts about the delimitation of the species ''Coregonus lavaretus'' and about the number of species in the genus ''Coregonus'' in general. Lavaret In a narrow sense, ''Coregonus lavaretus'', or the lavaret, is considered to be endemic to Lake Bourget and Lake d'Aiguebelette in the Rhône river basin in France, whereas it formerly also occurred in Lake Geneva. According to this view there is a great number of distinct whitefish species in lakes, rivers and brackish waters of Central and Northern Europe. European whitefish (common whitefish) In the broad sense, ''Coregonus lavaretus'', in English referred to as the common whitefish or European whitefish, is widespread from central and northwest Europe to Siberia. Often called the ''C. lavaretus'' complex and considered as a superspecies, it encompasses many of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravenche
The gravenche (''Coregonus hiemalis''), also known as the Lake Geneva whitefish or the little fera, is a presumably extinct freshwater fish from Lake Geneva in Switzerland and France. Description The gravenche was a species of freshwater whitefish (Coregoninae) that reached a length between .Christian TrépeyCorégone (Féra - Palée)www.plongee-passion.ch The status of the gravenche is disputed because there are no specimens in museums. While Emile Dottrens described it as subspecies of the common whitefish ''Coregonus lavaretus'' in 1958, other experts like Maurice Kottelat regarded it as a full species endemic to Lake Geneva.Maurice Kottelat: ''European Freshwater Fisches.

Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Zooplankton
Zooplankton are the heterotrophic component of the planktonic community (the " zoo-" prefix comes from ), having to consume other organisms to thrive. Plankton are aquatic organisms that are unable to swim effectively against currents. Consequently, they drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton (cyanobacteria and microalgae), which are the plant-like component of the plankton community (the " phyto-" prefix comes from , although taxonomically ''not'' plants). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding), often generating biological energy and macromolecules through chlorophyllic carbon fixation using sunlightin other words, zooplankton cannot manufacture their own food, while phytoplankton can. As a result, zooplankton must acquire nutrients by feeding on other organisms such as phytoplankton, which are generally smaller t ...

Fennoscandia
__NOTOC__ Fennoscandia (Finnish language, Finnish, Swedish language, Swedish and ; ), or the Fennoscandian Peninsula, is a peninsula in Europe which includes the Scandinavian Peninsula, Scandinavian and Kola Peninsula, Kola peninsulas, mainland Finland, and Karelia. Administratively, this roughly encompasses the mainlands of Finland, Norway and Sweden, as well as Murmansk Oblast, much of the Republic of Karelia, and parts of northern Leningrad Oblast in Russia. Its name comes from the Latin words ''Fennia'' (Finland) and ''Scandia'' (Scandinavia). The term was first used by the Finnish geologist Wilhelm Ramsay in 1898. Geologically, the area is distinct because its bedrock is Archean granite and gneiss with very little limestone, in contrast to adjacent areas in Europe. The similar term Fenno-Scandinavia is sometimes used for Fennoscandia. Both terms are sometimes used in English to refer to a cultural or political grouping of Finland with Sweden, Norway and Denmark (the latter ...

Peled (fish)
The peled (''Coregonus peled''), also called the ''northern whitefish'', is a species of freshwater whitefish in the family Salmonidae. It is found in northern Europe and Asia. The peled is related to ciscoes of the ''Coregonus sardinella'' complex.Politov DV, Bickham JW, Patton JC (2004 Molecular phylogeography of Palearctic and Nearctic ciscoes ''Ann. Zool. Fennici'' 41:13-23. Description Smaller peled much resemble slim vendace or whitefish but as they grow larger they develop a deeper body which becomes less tapered and more blocky. The jaws are of equal length which is in contrast to the whitefish which has a snout longer than its lower jaw, and the vendace which has a projecting lower jaw. Another distinction is that the first gill arch has 50–65 gill rakers, a larger number than either of the other species. This fish grows to a length of about and a maximum weight of . It has a dark back, silvery flanks and white belly. Distribution and habitat The peled is native to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
