摘要幼体扩散对底栖物种的遗传结构有重要影响。但不同的物种可能会选择不同的幼虫扩散策略。为了研究双斑？种群的遗传结构和幼虫扩散策略，测定了双斑？线粒体COI基因658 bp的序列。在黄海和华东海域5个地点共采集到67个个体，获得24种单倍型。5个群体的平均单倍型多样性和核苷酸多样性分别为0.2000 ± 0.1541（舟山）~ 0.8333 ± 0.1265（南麂岛）和0.0003 ± 0.0005（舟山）~ 0.0026 ± 0.0019（南麂岛）。分子方差分析和成对FST分析表明，黄海和东海的C. bimaculata，支持本物种的高幼虫扩散能力，拒绝幼虫滞留。错配分布显示C. bimaculata经历了种群扩张。洋流中的幼虫漂流和最近的范围扩张可能是研究区域遗传结构很少的原因。
Abstract Larval dispersal may have an important effect on genetic structure of benthic species. However, different species may choose different larval dispersal strategy. To examine the population genetic structure and larval dispersal strategy of portunid crab Charybdis bimaculata, a 658 base pair (bp) fragment of mtDNA COI gene was sequenced in this species. In total, 67 individuals were collected from 5 locations in Yellow Sea and East China, and 24 haplotypes were obtained. Mean haplotype diversity and nucleotide diversity for the five populations ranged from 0.2000 ± 0.1541 (Zhoushan) to 0.8333 ± 0.1265 (Nanji island), and from 0.0003 ± 0.0005 (Zhoushan) to 0.0026 ± 0.0019 (Nanji island). Analysis of molecular variance and pairwise FST revealed no significant differentiation between the Yellow Sea and the East China Sea in C. bimaculata, supporting high larval dispersal ability in this species, rejecting larval retention. Mismatch distribution revealed that C. bimaculata had undergone population expansion. Larval drift in the ocean currents, and recent range expansion could be the reasons for little genetic structure in the studied area.
