Pairwise Fst divergence between 12 groups of <i>M. schimitscheki</i> produced between 1999 and 2008, expressing either a short (2 years: SD) or a prolonged diapause (4 years: PD) phenotype.

Individuals of the n-SD group were produced at a year n and emerged at year n+2. Individuals of the n-PD group were produced at a year n and emerged at year n+4. Both 2000-PD and 2002-PD groups were excluded from this analysis due to low sample sizes (N<10).This pairwise Fst matrix was obtained using eight microsatellite loci after applying the correction for null alleles implemented in GENEPOP. Fst values in bold were significantly different from 0 (P<0.05). The numbers of genotyped individuals in each group are in subscript.
