Chilean Mussel
The Chilean mussel''Mytilus chilensis'' (Hupé, 1854) Sealifebase.org or Chilean blue mussel is a species of Mytilus (bivalve), blue mussel native to the coasts of List of marine molluscs of Chile, Chile from BioBio region (37 ºS) to Cape Horn (55 ºS). Today genomic evidence confirmed that the native Chilean blue mussel is genetically distinct from the Northem Hemisfere ''M. edulis'', ''M. galloprovincialis'' and ''M. trossulus'' and also genetically different from ''Mytilus platensis", the another species of smooth shelled mussel from Southamerica.

D'Orbigny
Alcide Charles Victor Marie Dessalines d'Orbigny (6 September 1802 – 30 June 1857) was a French naturalist who made major contributions in many areas, including zoology (including malacology), palaeontology, geology, archaeology and anthropology. D'Orbigny was born in Couëron (Loire-Atlantique), the son of a ship's physician and amateur naturalist. The family moved to La Rochelle in 1820, where his interest in natural history was developed while studying the marine fauna and especially the microscopic creatures that he named "foraminiferans". In Paris he became a disciple of the geologist Pierre Louis Antoine Cordier (1777–1861) and Georges Cuvier. All his life, he would follow the theory of Cuvier and stay opposed to Lamarckism. South American era D'Orbigny travelled on a mission for the Paris Museum, in South America between 1826 and 1833. He visited Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, Argentina, Paraguay, and Brazil, and returned to France with an enor ...

Lamy
Lamy is a German pen manufacturing company. Josef Lamy, who was a sales representative for Parker Pen in Germany, founded the business in 1930 by purchasing the Orthos pen manufacturer. Lamy was a pioneer in the use of moulded synthetic plastics to make their products. Lamy was run by Josef Lamy's son, Manfred, until his retirement in 2006. He was succeeded by Bernhard M. Rösner. Products manufactured by Lamy include fountain, ballpoint pens, and mechanical pencils. History In 1984, newspapers reported that Lamy's export share increased to 33 percent of turnover. In 1986, Lamy, Montblanc, and Parker held among them 70–80 percent of the West German market. Export markets then consisted of the United States, Japan, and Austria. Lamy hoped to expand that export share to 50 percent of turnover, which stood at approximately 40 million Deutschmark (DM) for 1985. Turnover for Lamy increased to 48 million DM for 1987, then employing 350 people, increasing to 54 million DM in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mytilus (bivalve)
''Mytilus'' is a Cosmopolitan distribution, cosmopolitan genus of medium to large-sized edible, mainly Saline water, saltwater mussels, marine (ocean), marine bivalve molluscs in the family (biology), family Mytilidae. Description Mussels have a gray to blue-purple, fully grown shell about 5 - 10 centimeters long with an elongated oval shape. They follow the general blueprint of the mussels. They consist of a right and left half of the shell, which are held together with an elastic lock strap (ligament). The shell is made up of 3 layers: the top layer of organic material (periostracum), the middle thick layer of lime (ostracum) and the innermost, valuable, silver-white shiny mother-of-pearl layer (hypostracum). In the shell of the mussel there are two gills with gill leaves that are well supplied with blood. Between the gills is a muscular foot with the byssus gland. With the help of the protein contained in the mussel and iron filtered from the sea, this gland produces the by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aquaculture
Aquaculture (less commonly spelled aquiculture), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus). Aquaculture involves cultivating freshwater, brackish water and saltwater populations under controlled or semi-natural conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture, commonly known as marine farming, refers specifically to aquaculture practiced in seawater habitats and lagoons, opposed to in freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain fish products as food. Aquaculture can also be defined as the breeding, growing, and harvesting of fish and other aquatic plants, also known as farming in water. It is an environmental source of food and commercial product which help to improve healthier habitats and used to recon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mytilus Edulis
The blue mussel (''Mytilus edulis''), also known as the common mussel, is a medium-sized edible marine (ocean), marine bivalve mollusc in the family (biology), family Mytilidae, the mussels. Blue mussels are subject to commercial use and intensive aquaculture. A species with a large range, empty shells are commonly found on beaches around the world. Systematics and distribution The ''Mytilus edulis'' complex Systematically blue mussel consists of a group of (at least) three closely related taxa of mussels, known as the ''Mytilus edulis'' complex. Collectively they occupy both coasts of the North Atlantic (including the Mediterranean) and of the North Pacific in temperate to polar waters, as well as coasts of similar nature in the Southern Hemisphere. The distribution of the component taxa has been recently modified as a result of human activity. The taxa can hybridise with each other, if present at the same locality. *''Mytilus edulis'' sensu stricto: Native to the North Atla ...

Single-nucleotide Polymorphism
In genetics, a single-nucleotide polymorphism (SNP ; plural SNPs ) is a germline substitution of a single nucleotide at a specific position in the genome. Although certain definitions require the substitution to be present in a sufficiently large fraction of the population (e.g. 1% or more), many publications do not apply such a frequency threshold. For example, at a specific base position in the human genome, the G nucleotide may appear in most individuals, but in a minority of individuals, the position is occupied by an A. This means that there is a SNP at this specific position, and the two possible nucleotide variations – G or A – are said to be the alleles for this specific position. SNPs pinpoint differences in our susceptibility to a wide range of diseases, for example age-related macular degeneration (a common SNP in the CFH gene is associated with increased risk of the disease) or nonalcoholic fatty liver disease (a SNP in the PNPLA3 gene is associated with inc ...

Mediterranean Mussel
The Mediterranean mussel (''Mytilus galloprovincialis'') is a species of bivalve, a marine (ocean), marine mollusc in the family (biology), family Mytilidae. It is an invasive species in many parts of the world, and also an object of aquaculture. Systematics ''Mytilus galloprovincialis'' is one of the three principal, closely related species in the ''Mytilus edulis'' complex of blue mussels, which collectively are widely distributed on the temperate to subarctic coasts of both the Northern and Southern Hemispheres, and often are dominant inhabitants on hard substrates of the intertidal and nearshore habitats. ''M. galloprovincialis'' will often hybridize with its sister taxa, the closely related ''Mytilus edulis'' and ''Mytilus trossulus'', when they are found in the same locality. ''M. galloprovincialis'' is considered the most warm-water-tolerant species of the three, and has the most southerly distribution in Europe and North America.

Introgression
Introgression, also known as introgressive hybridization, in genetics is the transfer of genetic material from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species. Introgression is a long-term process, even when artificial; it may take many hybrid generations before significant backcrossing occurs. This process is distinct from most forms of gene flow in that it occurs between two populations of different species, rather than two populations of the same species. Introgression also differs from simple hybridization. Simple hybridization results in a relatively even mixture; gene and allele frequencies in the first generation will be a uniform mix of two parental species, such as that observed in mules. Introgression, on the other hand, results in a complex, highly variable mixture of genes, and may only involve a minimal percentage of the donor genome.

Molluscs Of South America
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species. The gastropods ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
