Table 6 Results of population expansion tests on the four species. Fu’s F S , Tajima’s D and mismatch distribution estimate (τ) and the real expansion time (t) with 90 % credibility intervals in parentheses for each species are included. All COI sequences of S. japonica were divided into two groups: northern group and southern group, according to the phylogenetic analyses (See the results in the phylogenetic analysis). Reference: Cellana toreuma, Dong et al. [20]; Sargassum horneri, Hu et al. [36]; Atrina pectinata, Liu et al. [37]. *P < 0.05; **P < 0.01, ***P < 0.001
