利用遗传学数据对中国沿海帽贝（Cellanatoreuma）沿着的地理分布进行了研究，以了解历史事件、海流特别是长江淡水排放对具有有限幼虫扩散能力的潮间带物种的连通性的影响。15个群体的遗传多样性分析表明，对分布于黄海、东海和南海的418个不同海区的猪口鱼（toreuma）的线粒体细胞色素c氧化酶亚基I基因进行了部分序列测定。 用CONTRIB分析了群体单倍型频率的遗传多样性和遗传分化，用AMOVA分析了群体的遗传结构。从中性检验和不匹配分布检验两个方面对历史人口扩张进行了评估。在所鉴定的30种单倍型中，1号单倍型（H1）在所有群体中均占优势，1号单倍型（H2）在YS群体中相对丰富。YS组与其他两组的FST值相对较高，组间变异率为10.9%。高核苷酸和基因多样性的YS，大的成对遗传距离和相对较高的百分比之间的变化，表明这组是相对孤立的ECS和SCS。这可能是由历史事件，洋流和人口扩张驱动的。我们认为，长江的淡水排放可能作为限制北方种群幼虫向南扩散的物理屏障，在决定YS群与中国其他种群的分离中起着特别重要的作用。猪笼草
Genetic data were used to measure the phylogeographic distribution of the limpet, Cellana toreuma along the China coast in order to acsertain impacts of historic events, ocean currents and especially freshwater discharge from the Yangtze River on the connectivity of intertidal species with limited larval dispersal capability. Genetic variation in 15 populations of C. toreuma (n = 418), ranging from the Yellow Sea (YS), East China Sea (ECS) and South China Sea (SCS), were determined from partial mitochondrial cytochrome c oxidase subunit I gene. Genetic diversity and divergence based on haplotype frequencies were analyzed using CONTRIB, and AMOVA was used to examine genetic population structure. Historic demographic expansions were evaluated from both neutrality tests and mismatch distribution tests. Among the 30 haplotypes identified, a dominant haplotype No. 1 (H1) existed in all the populations, and a relatively abundant private haplotype (H2) in YS. Pairwise FST values between YS and the other two groups were relatively high and the percentage of variation among groups was 10.9%. The high nucleotide and gene diversity in the YS, with large pairwise genetic distances and relatively high percentages of variation among groups, suggests that this group was relatively isolated from ECS and SCS. This is likely driven by historic events, ocean currents, and demographic expansion. We propose that freshwater discharge from the Yangtze River, which may act as physical barrier limiting the southward dispersal of larvae from northern populations, is especially important in determining the separation of the YS group from the rest of the Chinese populations of C. toreuma.
