Abstract
The genetic variability of microsatellite DNA has been studied for the first time for five loci in the common bream Abramis brama (L.) from lakes Sebezhskoye and Necheritsa of the Sebezhsky National Park lake system (Pskov oblast). The results demonstrate the uniformity of estimates of the genetic variability of the bream in the lake system. Estimates of the allelic diversity of microsatellite loci and the expected heterozygosity of local bream groups do not differ significantly. The total genetic differentiation of bream is θ = 0.004, 95% CI (–0.01; 0.01), and is statistically insignificant. The Bayesian analysis of the studied multilocus genotypes has not revealed any population–genetic structure. The results indicate a high level of gene flow between local bream groupings and make it possible to assume the presence of a genetically unified panmixed population in the Sebezhsky National Park lake system.
摘要首次研究了塞别日斯基国家公园湖泊系统（普斯科夫州）塞别日斯科耶湖和涅切利察湖中普通鳊鱼（Abramis brama (L.)）五个位点的微卫星 DNA 遗传变异性。结果表明，对湖泊系统中鳊鱼遗传变异性的估计是一致的。微卫星位点等位基因多样性的估计值和当地鳊鱼群体的预期杂合度没有显著差异。鳊鱼的总遗传差异为θ = 0.004，95% CI (-0.01; 0.01)，在统计学上不显著。对所研究的多焦点基因型进行贝叶斯分析，未发现任何种群遗传结构。结果表明，当地鳊鱼群体之间的基因流动程度很高，因此可以认为塞别日斯基国家公园湖泊系统中存在一个基因统一的泛混种群。
