Geographic structure in the European flat oyster (Ostrea edulis L.) as revealed by Microsatellite polymorphism.
Genetic differentiation of the flat oyster (Ostrea edulis) was studied along the European coast, from Norway to the Black Sea, by means of variation at five microsatellite loci. The results show a mild but significant isolation-by-distance profile, a noticeable between-sample variance in expected heterozygosity, and a tendency for Atlantic populations to be less variable than Mediterranean ones...
متن کاملEuropean fl at oyster - Ostrea edulis
Distribution Th e European fl at oyster, Ostrea edulis, a native of Europe, occurs naturally from Norway to Morocco in the North-Eastern Atlantic and in the whole Mediterranean Basin (Fig.1) (1). It has been a harvested species for at least 6000 years. Natural populations are also observed in eastern North America, from Maine to Rhode Island, following intentional introductions in the 1940s and...
متن کاملCharacterization of 27 microsatellite loci in the European flat oyster Ostrea edulis.
The flat oyster Ostrea edulis is native to Europe and populations have been severely depleted by the parasite Bonamia ostreae since the 1980s. Additional genetic markers are required to improve population genetics study and linkage map development for selection for B. ostrea-resistance in this species. Here, we characterized 27 novel microsatellite loci for O. edulis. Number of alleles per locu...
متن کاملReduced female gene flow in the European flat oyster Ostrea edulis.
The geographical structure of 15 natural populations of the flat oyster (Ostrea edulis L.) was assessed by single-strand conformation polymorphism (SSCP) of a 313-base-pair (bp) fragment of the mitochondrial 12S-rRNA gene. Fourteen haplotypes were observed, with one being dominant in the Mediterranean samples and another one in the Atlantic populations. The geographically extreme populations sa...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
