对采自中国大陆和台湾地区13个地点的银角鲨（Squalidus argentatus）样品进行了系统地理学分析，以研究银角鲨的地理分布。对9个水系的160份标本进行了线粒体DNA cyt B基因的95种单倍型分析。结果表明，S.阿根廷人通过系统发育分析，揭示了两个主要的系统发育单倍型组，A和B。群间分歧的程度（3.96%）表明这些群在大约455万年前分歧。单倍型网络和群体分析表明，显着的遗传结构（FST = 0.775），在很大程度上与地理位置的人口。根据SAMOVA分析结果，将这些群体划分为长江-珠江、钱塘-闽江、九龙-北江和台湾四个群体。错配分布分析、中性检验和贝叶斯天际线图表明，谱系A和B分别在大约35万年前和0.04万年前出现了显著的种群扩张。我们发现了强大的地理组织的单倍型分支在不同的地理尺度，可以解释的情节分散和人口扩张，然后由人口碎片化和限制基因流。
Phylogeographical analyses on Squalidus argentatus samples from thirteen localities within mainland China and Taiwan were conducted for biogeographic studies, as their dispersal strictly depends on geological evolution of the landmasses. A total of 95 haplotypes were genotyped for mtDNA cyt b gene in 160 specimens from nine river systems. Relatively high levels of haplotype diversity (h = 0.984) and low levels of nucleotide diversity (π = 0.020) were detected in S. argentatus. Two major phylogenetic haplotype groups, A and B, were revealed via phylogenetic analysis. The degree of intergroup divergence (3.96%) indicates that these groups diverged about 4.55 myr (million years) ago. Haplotype network and population analyses indicated significant genetic structure (FST = 0.775), largely concordant with the geographical location of the populations. According to SAMOVA analysis, we divided these populations into four units: Yangtze-Pearl, Qiantang-Minjiang, Jiulong-Beijiang and Taiwan groups. Mismatch distribution analysis, neutrality tests and Bayesian skyline plots indicated a significant population expansion for lineage A and B, approximately dated 0.35 and 0.04 myr ago, respectively. We found strong geographical organization of the haplotype clades across different geographic scales that can be explained by episodes of dispersal and population expansion followed by population fragmentation and restricted gene flow.
