An ensemble forecasting of current and past distribution of R. palmatus and R. grayanus based on the bioclimatic variables. Sets of uncorrelated bioclimatic variables were used for each species. Probability of occurrence maps (a, b) and projected distribution of the suitable climates in the past (approx. 20,000 years ago; c, d) in R. palmatus (a, c) and R. grayanus (b, d). Dashed lines indicate the known current southern and northern limits of R. palmatus (a) and R. grayanus (b), respectively.
