Fitted estimates and significance levels of linear mixed models for seedling germination, survival and growth.

Minimal adequate model outputs for the effects of precipitation reduction (PR) treatment, acorn fresh biomass (Acorn), gap fraction (GF), soil water content (SWC) and their respective interactions on germination, total survival (ST), survival of emerged plants (SEP), height, shoot biomass, root biomass of the extracted root systems, contact ectomycorrhizal colonization (ECMc) and short + medium ectomycorrhizal colonization (ECMsm). R2m represents the variance explained by fixed factors and R2c represents the variance explained by fixed and random factors. NA = non applicable, as R2c cannot be computed for beta binomial distributions. *** for P<0.001, ** for P<0.01, * for P<0.05, + for P<0.07. Blanks indicate that the respective variables was not retained in the minimal adequate models, whereas the estimates with a lack of symbol (star or plus) are not statistically significant, but the predictor was retained in the minimal adequate model.
