logLik log-likelihood estimation, AICc Akaike information criterion; p-value, significant value below 0.05; marginal R², variance explained by fixed effects; conditional R², variance explained by both fixed and random effects. PC1 represents a light gradient, PC2 a soil fertility, rock surface, soil moisture, and pH gradient
