Final models for the size diversity of cavity nesting bees following backward elimination of the explanatory variables with a P‐value <0.10 (Table S6, Supporting information). Models were fitted using Poisson (Functionally singular species richness_bees) and Quasipoisson (Community weighted mean_bees and Functional dispersion_bees) generalized linear models (GLMs). Large wood boring beetle species excavate cavities with diameters ≥3 mm which may be used as nest sites by cavity nesting bees. Nagelkerke R ² values are shown
