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 pā<ā0.001 and *
indicating pā<ā0.05, and na indicating non-significant.
