Fig. 2: Standardized coefficient of regression between each of phylogenetic metrics and each of climatic and historical climatic variables and within-region variability of elevation, temperature, and precipitation.
A red dot represents a standardized coefficient derived from a single model including all regions across the world; a blue dot represents the average value of six standardized coefficients derived from six models, each of which included regions in one of the six biogeographic continents. 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; abbreviations of current climatic variables: Tmean mean annual temperature, Tmin minimum temperature of the coldest month, Tseas temperature seasonality, Pmean annual precipitation, Pmin precipitation during the driest month, Pseas precipitation seasonality; abbreviations for historical climatic variables are: Tanom temperature anomaly, Tvel temperature velocity, Panom precipitation anomaly, Pvel precipitation velocity; abbreviations of within-region variability: Esd standard deviation of elevation, Tsd standard deviation of mean annual temperature, Psd standard deviation of annual precipitation.
