Statistical significances of the influence of the treatment for the relative amount of Brassica napus (OSR) pollen in brood cells (beta regression model) of Osmia bicornis

	Amount of OSR pollen
Intercept	−1.69 ± 0.09***
Treatment	−0.50 ± 0.10***

Nesting blocks from which pollen was collected were either situated in a landscape with OSR fields treated with clothianidin seed dressing (test site) or untreated fields (reference site) and placed at the edge of the fields (edge) or ca. 100 m distant from the fields (distant). The intercept is the estimated mean value of the dependent variable, when all continuous variables are held at 0 and all categorical variables are held at their baseline levels. Positive values indicate positive interaction, negative values indicate negative interaction. Given are parameter estimates ± Standard deviation

***p < 0.001; **p < 0.01; *p < 0.05
