Coregonus Pallasii
''Coregonus pallasii'' is a putative species of whitefish in the family Salmonidae, part of the ''Coregonus lavaretus'' complex (European whitefish). It is a lacustrine fish, indicated to live in large lakes of Sweden, Finland and Karelia (Russia). A typical size is 42 cm and maximum size 60 cm. In Sweden, the name ''C. pallasii'' has been used of a whitefish form known as ''aspsik'' in the large lakes of the northern river basins, including lakes Pakijaure, Hornävan, Storlaisan, Storuman, Vojmsjön and Storlögdan. Currently these populations are no more considered separate from the common whitefish, but as a morphotype within ''Coregonus maraena''. Also in Finland, only one species of the ''C. lavaretus'' group is recognized, and ''C. lavaretus f. pallasi'' has been used to denote the zooplankton-feeding ecomorph Ecomorphology or ecological morphology is the study of the relationship between the ecological role of an individual and its morphological adaptations.

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "'' Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coregonus
''Coregonus'' is a diverse genus of fish in the salmon family (Salmonidae). The ''Coregonus'' species are known as whitefishes. The genus contains at least 68 described extant taxa, but the true number of species is a matter of debate. The type species of the genus is '' Coregonus lavaretus''. Most ''Coregonus'' species inhabit lakes and rivers, and several species, including the Arctic cisco (''C. autumnalis''), the Bering cisco (''C. laurettae''), and the least cisco (''C. sardinella'') are anadromous, moving between salt water and fresh water. Many whitefish species or ecotypes, especially from the Great Lakes and the Alpine lakes of Europe, have gone extinct over the past century or are endangered. Among 12 freshwater fish considered extinct in Europe, 6 are ''Coregonus''. All ''Coregonus'' species are protected under appendix III of the Bern Convention. Taxonomy Phylogenetic evidence indicates that the most basal member of the genus is the highly endang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmonidae
Salmonidae is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes . It includes salmon (both Atlantic and Pacific species), trout (both ocean-going and landlocked), chars, freshwater whitefishes, graylings, taimens and lenoks, which are collectively known as the salmonids ("salmon-like fish"). The Atlantic salmon (''Salmo salar''), whose Latin name became that of its genus ''Salmo'', is also the source of the family and order names. Salmonids have a relatively primitive appearance among the teleost fish, with the pelvic fins being placed far back, and an adipose fin towards the rear of the back. They have slender bodies, with rounded scales and forked tails, and their mouths contain a single row of sharp teeth. Although the smallest species is just long as an adult, most are much larger, with the largest reaching . All salmonids spawn in fresh water of upper reaches of rivers and creeks, but in many cases, the fish spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coregonus Lavaretus
''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 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. Of course this has absolutely nothing to do with its actual origin in the Caucasus, as with other things falsely attributed to originating in France, such as grapes which originated in Turkey, Iran and Australia. European whitefish (common whitefish) In the broad sense, ''Coregonus lavaretus'', referred to as the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lacustrine
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karelia
Karelia ( Karelian and fi, Karjala, ; rus, Каре́лия, links=y, r=Karélija, p=kɐˈrʲelʲɪjə, historically ''Korjela''; sv, Karelen), the land of the Karelian people, is an area in Northern Europe of historical significance for Russia (including the Soviet era), Finland, and Sweden. It is currently divided between northwestern Russia (specifically the federal subjects of the Republic of Karelia and Leningrad Oblast) and Finland (the regions of South Karelia, North Karelia, and the eastern portion of modern-day Kymenlaakso). Use of name Various subdivisions may be called Karelia. Finnish Karelia was a historical province of Finland, and is now divided between Finland and Russia, often called just ''Karjala'' in Finnish. The eastern part of this chiefly Lutheran area was ceded to Russia after the Winter War of 1939–40. The Republic of Karelia is a Russian federal subject, including East Karelia with a chiefly Russian Orthodox population. Within present-da ...

Storuman
Storuman ( sma, Luspie, Ume Sami: ''Lusspie'') is a locality and the seat of Storuman Municipality in Västerbotten County, province of Lapland, Sweden with 2,207 inhabitants in 2010. It is situated by the Ume River, at the southeastern end of Lake Storuman. History It is believed that the first Swedish people who came to the area, were from Vilhelmina to the south and settled here around 1741. The place became known as 'Luspen', derived from a local river of the same name. Until 1912, the population of the village was about 40 inhabitants living in eight farms, but that changed when a railway station was built (Inland Line) around 1924. The village quickly grew and became known as an important centre for hydroelectric power and the timber industry. It later became a popular tourist spot as well. The heraldic shield (the weapon of the town) is a Wild man, based on the name of the village and the symbols of the strength and determination of the people of Lapland. Notable pe ...

Coregonus Maraena
''Coregonus maraena'', referred to in English as the maraene, maraena whitefish or the whitefish, is a whitefish of the family Salmonidae that occurs in the Baltic Sea basin - in the sea itself and the inflowing rivers, and in several lakes as landlocked populations. It is found in Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Netherlands, Norway, Poland, Slovakia (Štrbské pleso), Russia and Sweden. As of 2013, it has been listed as a vulnerable species by the IUCN and as endangered by HELCOM. It is an extremely important fish within the Baltic Sea ecosystem, both for population equilibrium and for the local diets of the surrounding human population. Due to a variety of factors, mostly overfishing, the maraena’s population dwindled to near-extinction levels. Thus, rampant repopulation was enacted to preserve this important fish. In the Baltic basin countries, this species has traditionally been known as '' Coregonus lavaretus'' (the common whitefish). The name ''Co ...

Ecomorph
Ecomorphology or ecological morphology is the study of the relationship between the ecological role of an individual and its morphological adaptations. The term "morphological" here is in the anatomical context. Both the morphology and ecology exhibited by an organism are directly or indirectly influenced by their environment, and ecomorphology aims to identify the differences. Current research places emphasis on linking morphology and ecological niche by measuring the performance of traits (i.e. sprint speed, bite force, etc.) associated behaviours, and fitness outcomes of the relationships. Current ecomorphological research focuses on a functional approach and application to the science. A broadening of this field welcomes further research in the debate regarding differences between both the ecological and morphological makeup of an organism. Development of ecomorphology The roots of ecomorphology date back to the late 19th century.Bock, W. J. 1994. Concepts and methods in ec ...
