Slope estimates (β) of zero-inflated generalized linear mixed-effect models and 95% (CI95%) and 90% (CI90%) bootstrapped confidence intervals are shown. Significant effects (i.e. the 95% CI does not include zero) and effects with weak evidence (i.e. only the 90% CI does not include zero) are marked bold and italic, respectively. Species codes are given in Table 1 .
