Figure 1.
Map of sampling localities and allele frequencies at locus H16.
Sample numbers match those in Table 1. Pie charts denote allele frequencies at H16, in which each color represents one allele identity. Well supported and less well supported barriers to gene flow based on neutral microsatellites are also shown with broken lines that are proportional to replicates support. The sea areas are shown in abbreviations corresponding to Table 1. The southward China Coastal Cold Current and northward Taiwan Warm Current are also shown with arrows.
Figure 2.
Results of the outlier tests using BAYESCAN.
Loci identified as significant outliers under the decisive criterion of Jeffrey’s interpretation are denoted as solid circles.
Figure 3.
Results of the outlier tests using LOSITAN (outliers are above the 99% confidence interval curve) and under hierarchical island model using Arlequin (H16 and HSP27 are still outliers, whereas H51 and H65 lost significance as outliers).
Figure 4.
PCA plotting of population differentiation based on (a) neutral microsatellites; (b) locus H16; (c) locus HSP27.
Figure 5.
Plotting results of the program STRUCTURE for neutral loci with K ranging from 3 to 5 and for whole data set with K from 2 to 4, respectively.
Sample identities and its corresponding geographical regions are also showed.
