  • ** P ≤ 0.005 or P ≥ 0.995,

  • *** P ≤ 0.0005 or P ≥ 0.9995.

  • a N1/N0 = 0.57, t0 = 0, and t1 = 0.6 in N generations.

  • b N1/N0 = 0.21, t0 = 0.07, and t1 = 0.25 in N generations.

  • c Two refugia, Nanc/N0 = 0.1, Nrefugia/N0 = 0.001; time of merging refugia was set to 5.6 × 10−2 and the duration of the refugia was 5 × 10−3 expressed in N generations.

  • d Bottleneck, Nanc/N0 = 0.15, Nbottleneck/N0 = 0.003; time of bottleneck was set to 4 × 10−2 and the duration of the bottleneck was 10−2 expressed in N generations.

  • P is the probability of having a smaller value than that observed. P ≤ 0.0250 and P ≥ 0.9750 are considered significant. For Tajima's D and D/Dmin, n = 195 loci and for Fu and Li's D and Fay and Wu's H, n = 43. Levels of variation were the same as used in Table 4.
