Figure 3
Genetic architecture of the high-altitude population of Biscutella laevigata. The spatial interpolation of the first between-group Eigenanalysis (BPCA) score among plots over the core population is shown. Colours correspond to classes of quantiled-BPCA scores detailed in the panel. Plots are marked with circles, which represent the within-plot Shannon index of genetic diversity in three equal classes (according to the panel: small, medium and big circles represent low, intermediate and high genetic diversity, respectively). Note that most of the high-diversity plots are located at the contact zone among genetically homogeneous patches.
