Table 2 Polymorphism at the seven microsatellite loci used in this study. Size range gives the size (in base pairs) of the smallest and largest alleles. N_all is the total number of alleles found at each locus. R_all is the mean allelic richness per loci (Petit et al, 1998), averaged over populations and s.d. its standard deviation
