Estimated time of expansion based on cyt b data and the corresponding 95% confidence intervals (95% CI), using a mutation rate (μ) of 1.133E-05 substitutions per year. The cyt b lineages representing E. reichertii (A) and E. lucius (B, E, F), respectively are denoted in parenthesis. Significant values of Tajima’s D and Fu’s F are indicated in bold.
