To test the null hypothesis of panmixia, genetic differentiation among the sampling sites was calculated with pairwise [F.sub.st] values (Weir & Cockerham 1984) and a permutation test with 1,000 iterations was used to assess the statistical significance (Genetix Version 4.02).
The null hypothesis of panmixia (random distribution of haplotypes among populations) was also tested using an exact test of population differentiation (Raymond & Rousset 1995).
