Fig. 4: Partition of the variation in phylogenetic metrics of angiosperms in geographic regions within biogeographic continents explained by current climatic variables (C), historical climatic variables (H), and within-region variability of elevation, temperature, and precipitation (V).
Each variation partitioning analysis included two sets of explanatory variables. Each bar represents the average value of the six biogeographic continents. Note that the total amount of the variation explained by the pairwise groups of explanatory variables in each panel is the sum of the three bars in the panel. See Methods for explanatory variables in each of the three groups. Abbreviations of phylogenetic metrics: PD area-corrected phylogenetic diversity, MPD mean pairwise distance, RPD relative phylogenetic diversity, PDses standardized effect size of phylogenetic diversity, MPDses standardized effect size of mean pairwise distance. An asterisk above a bar represents a negative value resulting from the variation partition. Source data are provided as a Source Data file.
