Alternative mating strategies in Atlantic salmon and brown trout.
By screening variable number of tandem repeat (VNTR) loci, multiple paternity within clutches has been found in wild populations of southern European Atlantic salmon (Salmo salar) and brown trout (Salmo trutta). For Atlantic salmon, we determined the relative contribution of alternative male phenotypes to the next generation. Individual males that are morphologically juvenile yet sexually matur...
متن کاملMaterial and genetic benefits of female multiple mating and polyandry
The maintenance of female polyandry has traditionally been attributed to the material (direct) benefits derived from male mating resources (e.g. nuptial gifts) accrued by multiple mating. However, genetic (indirect) benefits offer a more robust explanation since only polyandrous, not monandrous, females may gain both material benefits from multiple mating and genetic benefits from multiple sire...
متن کاملPopulation Social Structure Facilitates Indirect Fitness Benefits from Extra-Pair Mating
Despite decades of research, empirical support for the “compatible genes” and “good genes” hypotheses as explanations for adaptive female extra-pair mating remains discordant. One largely un-tested theoretical prediction that could explain equivocal findings is that mating for compatible genes benefits should reduce selection for good genes. However, this prediction does not consider demographi...
متن کاملPhylogeography and taxonomic status of trout and salmon from the Ponto‐Caspian drainages, with inferences on European Brown Trout evolution and taxonomy
Current taxonomy of western Eurasian trout leaves a number of questions open; it is not clear to what extent some species are distinct genetically and morphologically. The purpose of this paper was to explore phylogeography and species boundaries in freshwater and anadromous trout from the drainages of the Black and the Caspian Seas (Ponto-Caspian). We studied morphology and mitochondrial phylo...
متن کاملUse of sequence data from rainbow trout and Atlantic salmon for SNP detection in Pacific salmon.
Single nucleotide polymorphisms (SNPs) are a class of genetic markers that are well suited to a broad range of research and management applications. Although advances in genotyping chemistries and analysis methods continue to increase the potential advantages of using SNPs to address molecular ecological questions, the scarcity of available DNA sequence data for most species has limited marker ...
