Figure 4: Current climatic suitability (number of grid cells; a) and predicted change to current climatic suitability under moderate (SPP1) (b) and severe (SSP5) (c) climate change by 2081-2100 of cultivated non-naturalized and naturalized plants of Southern Africa. The grey dots represent the number of grid cells predicted to be suitable for each species under current conditions (a) and are predicted to be lost or gained in the future (b, c). The thick horizontal line in each box indicates the median number of cells predicted to be suitable under the current climate (a) and changed to suitable or not suitable under future climate scenarios. The boxes indicate the interquartile range, and the whiskers extend outside the box to 1.5 times the interquartile range. Asterisks indicate significant differences between the compared means according to the GLMs models, with *** indicating p < 0.001 and * indicating p < 0.05, and na indicating non-significant.
