Analysis of ecological suitability of three Coptis species. The colored ranges indicated different species and suitable areas at different levels. The potential suitable distribution of C. chinensis (A), C. chinensis var. brevisepala (B) and C. teeta (C) in China. (D) Contribution of 68 environmental variables to the distribution of three Coptis species. (E) Venn diagram of 16 contributing environmental variables affecting the distribution of three Coptis species. Effects of environmental variables classified into five categories (temperature, precipitation, solar radiation, water vapor pressure and altitude) on the distribution of Coptis species.
