n_a= observed number of alleles; n_e= effective number of alleles [51]; H_O= observed heterozygosity; H_E= Nei's [40] unbiased expected heterozygosity; I_nor = normalized Shannon's Index [41, 42]. Sample size is given both as number of individuals analysed and (between bracket) as average number of data per locus. The incomplete genotyping is due to technical reasons.
