  1. Population and area codes correspond to those reported in Table 1. Values reported are: number of individuals analysed (N); number of haplotypes (Nhap); haplotype (h) and nucleotide (π) diversity (the latter expressed in percentage); T-D, Tajima D test; F-Fs, Fu’s Fs test; R2, Ramos-Onsins and Rozas R2 test. Significant values (P < 0.05) are in bold
