中华绒螯蟹（Eriocheir）广泛分布于西太平洋。在更新世，由于温度的变化，它们被迫进入冰期退缩和间冰期扩张的反复循环。本研究利用线粒体DNA分子标记对绒螯蟹的遗传多样性和种群地理结构进行了分析。所有结果支持中华绒螯蟹4个地理种群的重新划分。同域居群间可能存在着某些共享单倍型的渐渗现象。星形网络、单峰分布和显著负值的中性检验结果表明，种群近期曾有过扩张。
Mitten crabs (Eriocheir) were widely distributed in the West-Pacific Ocean. In response to change of temperature during the Pleistocene, they were forced into repeated cycle of glacial retreat and interglacial expansion. In the study, genetic diversity and phylogeographic structure of Eriocheir were analysed by mtDNA markers. All results supported the redivision of four geographic populations of mitten crabs corresponding to geographic distribution. And introgression of the sympatric populations might have happened for some shared haplotypes. Results of “star-like” network, unimodal curve of mismatch distributions and significantly negative values of neutral test suggested a recent population expansion.
