Scatterplot showing results from individual-based principal component analysis (PCA). The first two axes explain 34.64 and 22.84% of the variance among the 10 climatic variables. a Diploid (red) and polyploid (blue) cytotypes labelled inside the 95% inertia ellipses. b Biplot of objects and variables, in which arrows represent direction and magnitude of effects of environmental variables
