Mean similarity of BIOCLIM models for selected groups of Cyclamen. a) " Subgenera; b) Monophyletic groups from phylogeny (fig 7); c) Overall average for all Cyclamen; d) Randomisation replicates of subsets of Cyclamen for varying group sizes. * Similarity based on interpredictivity measure. ** N is number of species in clade. ***CI = confidence interval for the mean based on N(N-1) comparisons for a-c) and 100 replicates for d)
