The effects of annual mean temperature (Temp), annual precipitation (Prec), solar radiation (Solar), PC soil nutrients (Nutri), and standing biomass (Biom) on mean population characteristics of Anthyllis vulneraria along an altitudinal and a latitudinal gradient. Given are importance values from averaging over all possible models including these variables. For variables that are part of the best model with the lowest AICc (Supplementary Material Table S6) the sign of the regression coefficient is shown: + , positive; −, negative effect. For model details see Supplementary Material Table S5
