Allele frequencies. The cumulated frequencies of the R^x, R^x*, D, and S alleles are presented for each sample. The locality and year of collection are also indicated (bottom), as well as the number of analyzed individuals (N) and the species (top). Note that only samples with more than 10 individuals were considered to estimate the allelic frequencies using the maximum‐likelihood approach (see text and Table S3). Colors are the same than in Figure 1
