Fig. 1. Map showing study area and
11 sampling locations in Beibu Gulf, South China Sea.
Fig. 2. Haplotype network for Evynnis cardinalis on the basis of
nucleotide variation at the cytochrome c oxidase subunit I (COI) gene.
Each circle represents a unique haplotype, and its size is proportional
to the number of individuals sharing that specific haplotype. For each
branch with more than one mutational step each mutational step is
labelled.
Fig. 3. Pie diagrams showing the relative abundance of different
haplotypes across the eleven sampling sites (total number of different
haplotypes = 44). The size of each pie fraction is proportional to the
fraction of individuals with a given haplotype.
Fig. 4. Observed mismatch distributions (bars) and expected mismatch
distributions under sudden expansion model (line) of COI forEvynnis cardinalis from Beibu Gulf
Fig. 5. Bayesian skyline plot revealing the demographic trends ofEvynnis cardinalis in Beibu Gulf. The dark solid line is median
estimate under the assumption of per site mutation rate of 2% per
million years. The dark gray solid line shows the median obtained under
the assumption of per site mutation rate of 1% per million years, while
the light gray bottom line shows the median obtained under the
assumption of per site mutation rate of 3% per million years, and the
dashed lines show the 95% highest posterior density (HPD) limits.
