Then, we computed F ST 's and performed a Mantel test that resulted in a positive trend in the correlation (Mantel's r = 0.4173, p ‐value = 0.047; Figure 3 ) between geographical and genetic distance, even though that p ‐values varied around 0.05 depending on the permutation. 3.4 Genetic‐Environment Association ( GEA ) Analyses A PCA was conducted on the allele frequencies to identify latent factors within the populations and to assess the potential influence of population structure.
