Monoporeia Affinis
''Monoporeia affinis'', formerly referred to as ''Pontoporeia affinis'' ( el, Πόντος, ' = Pontus / Black Sea; , ' = to travel), is a small, yellowish benthic amphipod living in the Baltic Sea, the Arctic Sea and the lakes of the Nordic countries. Description ''Monoporeia affinis'' measures up to long when fully grown, with two pairs of antennae and one pair of black eyes. The legs arising from the first three segments of the abdomen are expanded basally to form broad plates. ''Monoporeia affinis'' closely resembles another benthic amphipod, '' Pontoporeia femorata'', which can be distinguished from ''M. affinis'' by its light red eyes. Ecology ''M. affinis'' is one of the Baltic glacial relicts. Originally a freshwater species, it also exists in lakes. ''M. affinis'' lives on soft bottoms, sometimes even as densely as 10,000–20,000 but usually hundreds to thousands of individuals per square metre. The amphipod has an important role in bioturbation (mixin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward L
Edward is an English given name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy and ...

Herring
Herring are forage fish, mostly belonging to the family of Clupeidae. Herring often move in large schools around fishing banks and near the coast, found particularly in shallow, temperate waters of the North Pacific and North Atlantic Oceans, including the Baltic Sea, as well as off the west coast of South America. Three species of ''Clupea'' (the type genus of the herring family Clupeidae) are recognised, and comprise about 90% of all herrings captured in fisheries. The most abundant of these species is the Atlantic herring, which comprises over half of all herring capture. Fish called herring are also found in the Arabian Sea, Indian Ocean, and Bay of Bengal. Herring played an important role in the history of marine fisheries in Europe, and early in the 20th century, their study was fundamental to the development of fisheries science. These oily fish also have a long history as an important food fish, and are often salted, smoked, or pickled. Herring are also known as ...

Gammaridea
Gammaridea is one of the suborders of the order Amphipoda, comprising small, shrimp-like crustaceans. Until recently, in a traditional classification, it encompassed about 7,275 (92%) of the 7,900 species of amphipods described by then, in approximately 1,000 genera, divided among around 125 families. That concept of Gammaridea included almost all freshwater amphipods, while most of the members still were marine. The group is however considered paraphyletic, and is under deconstruction by the amphipod taxonomists J. Lowry and A. Myers. In 2003 they moved several families from Gammaridea to join members of the former Caprellidea in a new suborder Corophiidea.A. A. Myers & J. K. Lowry (2003). "A phylogeny and a new classification of the Corophiidea Leach, 1814 (Amphipoda)". Journal of Crustacean Biology 23 (2): 443–485. doi:10.1651/0278-0372 Further, in 2013 another large suborder Senticaudata was established, which now encompasses much of the original Gammaridea, particul ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia ...

Finnish Institute Of Marine Research
The Finnish Institute of Marine Research (FIMR) ( fi, Merentutkimuslaitos and sv, Havsforskningsinstitutet) was a research institute founded in 1918 that was subordinate to the Ministry of Transport and Communications. The institute's main objective was to produce marine-science information to facilitate decision-making, for Finns and in international collaboration, and for use in seafaring. Biological research would not be included for several decades, and all four internal divisions were headed by physicists or geophysicists through the 1950s. The Institute was originally housed at Konstantinin Street 8 (now Meritullinkadun) on the Helsinki seaport, and in 1926 moved a mile south to a government building at 2 Tähtitornin St. There it remained until September 2005, when its headquarters became Dynamicum, a building it shares with the Finnish Meteorological Institute in Kumpula, Helsinki. The institute was closed in the beginning of 2009, and its functions were divided between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indicator Species
A bioindicator is any species (an indicator species) or group of species whose function, population, or status can reveal the qualitative status of the environment. The most common indicator species are animals. For example, copepods and other small water crustaceans that are present in many water bodies can be monitored for changes (biochemical, physiological, or behavioural) that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollutants in the ecosystem and about how long a problem may have been present, which physical and chemical testing cannot. A biological monitor or biomonitor is an organism that provides quantitative information on the quality of the environment around it. Therefore, a good biomonitor will indicate the presence of the pollutant and can also be used in an attempt to provide additional information about the amount and intensity of the exposure. A biological indicator is also the name g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Finland
The Gulf of Finland ( fi, Suomenlahti; et, Soome laht; rus, Фи́нский зали́в, r=Finskiy zaliv, p=ˈfʲinskʲɪj zɐˈlʲif; sv, Finska viken) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg in Russia to the east, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbors are located farthest in, near Saint Petersburg (including Primorsk). As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf. Proposals for a tunnel through the gulf have been made. Geography The gulf has an area of . The length (from the Hanko Peninsula to Saint Petersburg) is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxygen
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.Atkins, P.; Jones, L.; Laverman, L. (2016).''Chemical Principles'', 7th edition. Freeman. Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and ...
