| description | The East and South China Seas are rich in marine resources, but they are also under great pressure from climate change and human activities. Maintaining diversity and connectivity between communities is thought to be effective in mitigating these pressures. To assess the diversity and connectivity among the populations of <i>Ocypode ceratophthalmus</i> in the East and South China Seas, 15 populations from or near 15 marine protected areas in the two seas were studied using <i>COI</i> and <i>D-Loop</i> as genetic markers. The results showed that <i>O. ceratophthalmus</i> populations had high diversity, and the results of a hierarchical analysis of molecular variance and fixation index found that there were no significant genetic structures among these populations. High historical gene flow and high migration rates were further observed among populations by Migrate-n. Furthermore, the <i>COI</i> sequences further showed the asymmetric migration rate with a higher migration rate from south to north than from north to south. This information could provide recommendations for the management of marine protected areas in the East and South China Seas. |
