| Abstract: | Changes of coastal topography for Cenozoic Himalayan orogeny complicated the phylogeographical structure of marine species and deepened their divergences. To test the association between divergence and Cenozoic tectonic events, we analyzed the phylogeographical structure of Eriocheir japonica by combining molecular data and geographical environment events. The four distinct lineages obtained through phylogenetic reconstruction and network analysis demonstrated the significant genetic divergence among geographical populations. Furthermore, the divergence time between E. j. japonica in Japan and E. j. sinensis in China was about 10.5–11.5 mya, which was coincident with the opening of the Sea of Japan. The north-south divergence time (15.5–17.5 mya) was in the range of the occurrence of the Himalaya movement. We hypothesize that coastal topography, including the formation of Taiwan in the Himalaya movement and the opening of the Sea of Japan, contributed to the geographical subspeciation of marine species. Mitten crabs were inferred to originate from one ancient population with the oldest haplotype H6 and subsequently divide into northern and southern populations. Furthermore, the Japan lineage derived from northern population in China for the opening of the Sea of Japan. |
