Principal Component Analysis (PCA) correlations (factor loadings) of climatic variables (black circles) and seed morphophysiological traits (pink circles, red circles for correlations higher than 0.5) with the first two principal components (PC1′ and PC2′). Longitude, latitude and elevation, in grey, were treated as supplementary variables
