Current conditions (2010) and predicted variable changes between 2010 and 2050 (ΔV 2050) (mean and standard deviation SD) calculated across all sampling plots (n = 4752).

Only variables significant in the species’ models are considered. The changes in climate variables were directly obtained from the climate data (model: ECHAM5/CLM, scenario: A1B). Potential vegetation changes were derived from multiple regression models describing vegetation variables as a function of climate (see Table S4) which were calibrated under current (2010) and extrapolated to future (2050) climate conditions.
