Figure 3: Predicted change in current climatic suitability under
moderate future climate change (SSP1) (a) and severe climate change
(SSP5) (b) of cultivated alien plants of Southern Africa by 2081-2100
separated by their biomes. The dots represent the observed
mean of the predicted change of a certain group. The lines are the 95%
bootstrapped confidence intervals of the means of 1000 resamples from
the population of species of a certain group. Red, blue and black lines
indicate whether the mean of the group is significantly larger, small or
not different from zero. The violin plots show the distribution of the
means of predicted changes sampled by bootstrapping from the population
of all species. Red, blue, and black dots indicate whether the observed
means are significantly higher, lower, or not different from the random
expectations, respectively.
