| 摘 要： | 用23个微卫星DNA标记分析了2000年前后北海、威海和舟山花鲈(Lateolabrax maculatus)地理群体(A组)和2006年2个烟台花鲈群体(B组)的遗传结构.A组内各群体Nei氏期望杂合度相似、有轻微遗传分化、属同一自由交配群;A组组内及威海和北海地理群体内存在瓶颈事件.B组内2群体无显著遗传分化,组内及群体A发生过瓶颈事件.尽管威海群体与B组2个群体的Nei's期望杂合度、平均等位基因数相似,遗传距离小,属同一自由交配群,但威海群体与2个烟台群体间的遗传分化达到了显著水平,表明山东半岛沿海花鲈群体遗传结构从2000～2006年已发生一定程度的改变.

| Abstract: | The genetic structure of spotted sea bass(Lateolabrax maculatus) inhabiting the Chinese coast was determined with 23 microsatellite DNA markers. The Nei's expected heterozygosity of Beihai, Weihai and Zhoushan geographic populations(Group A) was similar to each other. These 3 populations differentiated slightly; however, the individuals collected around year 2000 belonged to a single panmictic group. The bottleneck event was detected in Group A as a whole and in Weihai and Beihai geographic populations. Two... |
