Results for the three GLMM models.

Interactions were found to be significant for richness and abundance but not for basal area. The applied distribution type is listed beneath the name of the respective dependent variable. Numbers in brackets denote standard errors. Pseudo-R² calculation followed Nakagawa & Schielzeth [40]. The marginal R2 shows the variation explained only by the fixed effects while the conditional R2 shows the variation of the fixed and random effects. For the negative-binomial abundance model calculation of R² was not possible hence we used the R2 of a Poisson model as a proxy.
