Lack of trophic polymorphism despite substantial genetic differentiation in sympatric brown trout (Salmo trutta) populations
Sympatric populations occur in many freshwater fish species; such populations are typically detected through morphological distinctions that are often coupled to food niche and genetic separations. In salmonids, trophic and genetically separate sympatric populations have been reported in landlocked Arctic char, whitefish and brown trout. In Arctic char and brown trout rare cases of sympatric, g...
متن کاملGenetic diversity of trout (genus Salmo) from its most eastern native range based on mitochondrial DNA and nuclear gene variation.
Russia and western Asia harbour trout populations that have been classified as distinct species and subspecies, most often on the basis of morphological and ecological variation. In order to assess their origins and to verify whether traditional taxonomy reflects their evolutionary distinctiveness, we documented their genetic relationships on the basis of mitochondrial DNA (mtDNA) RFLP, mtDNA s...
متن کاملشجره شناسی ماهی قزل‌آلای خال‌قرمز (Salmo trutta L. 1758) رودخانه جاجرود با استفاده از توالی ناحیه D-Loop
In this study phylogenetic relationship of the Jajrud River Brown trout Salmo trutta L. 1758 in the Namak Lake basin was analyzed using complete D-Loop sequence of the mitochondrial genome, compared to other Iranian populations of the species. The results clarified that Jajrud brown trout, similar to other Iranian brown trout populations belongs to the Danube phylogenetic lineage. The observed ...
متن کاملHuman mining activity across the ages determines the genetic structure of modern brown trout (Salmo trutta L.) populations
Humans have exploited the earth's metal resources for thousands of years leaving behind a legacy of toxic metal contamination and poor water quality. The southwest of England provides a well-defined example, with a rich history of metal mining dating to the Bronze Age. Mine water washout continues to negatively impact water quality across the region where brown trout (Salmo trutta L.) populatio...
متن کاملDNA sequence variation of the mitochondrial control region among geographically and morphologically remote European brown trout Salmo trutta populations.
Throughout its natural range, the brown trout Salmo trutta L. exhibits a complex pattern of morphological and life-history variation. This has led to considerable taxonomic confusion, hampering the understanding of the evolutionary history of the species. To document the phylogenetic relationships among morphologically and geographically remote brown trout populations across western Europe, we ...
