Biogeographic scenario. a) Inferred dispersal scenario between the biogeographic areas (colour coded “area ranges” as assessed by the buffered species occurrence data) depicted on the global study area. b) The phylogeny of Erica with a representation of ancestral areas derived from a single BSM analysis using the best tree and model (under DEC + J). c) Climate similarity between area ranges given as hypervolume corrected pairwise climate similarity (Schoener’s D; with D ≥ 0.5 in dark grey, and D < 0.5 in light grey; Table S8) with superimposed black arrows scaled to the dispersal rates per Ma inferred between areas (Table S13).
