title: [Genetic divergence in pink salmon introduced into the European north of Russia: microsatellite and allozyme variation analysis].
abstract: The 1985 introduction into the European North of Russia resulted in the formation of a large stock of pink salmon of the odd-year breeding line. To assess the divergence of the new population and the role of various microevolutionary factors, variation of four microsatellite loci and fifteen genes encoding proteins (allozymes) in samples of fish, running for spawning in rivers of the new area, and in samples from the donor population of the Ola River (Magadan oblast). In the generations 8 and 9 of the introduced pink salmon of the odd-year line, the genetic diversity (the number of alleles and the mean heterozygosity) both at allozyme and at microsatellite loci was significantly lower, than that in the donor population. The explanations of the decline in diversity are discussed. The first evidence for spatial genetic divergence in transplanted fish within the new area has been obtained; the divergence level may be comparable with that characteristic of native populations.
