Table 3. Results of GLMM testing of the influence of honey bee abundance on pollen depletion in white clover (Trifolium repens).

Covariates included, honey bee abundance, wild bee abundance, floral richness, floral density, and sampling period were included as covariates in the model. Predictors for each model were scaled and centered on zero. β is the coefficients for each predictor, CI is the 95% confidence intervals and p is the significance. Significant predictors of any of the three diversity metrics are in bold.
