Figure 2 from: Gehrke B (2018) Staying cool: preadaptation to temperate climates required for colonising tropical alpine-like environments. PhytoKeys 96: 111-125. https://doi.org/10.3897/phytokeys.96.13353

Figure 2 Relative contribution of in situ speciation and immigration to species richness in selected tropical alpine regions (pie charts on the left). Blue: in situ speciation, green: colonisation, light blue: uncertainty regarding in situ speciation, light green: uncertainty about colonisation. In the right pie charts, colonisation is further decoupled into species derived from other regions with alpine-like climate (black) and species that originated by colonisation from a different biome (red). Uncertainty is indicated by grey.
