Relationship between the number of flowers, the volume of nectar (µl), the number of pollen grains and the richness of animal-pollinated plants in bloom and the cover of plant species of forest edges. The line represents the estimate of the Generalised Linear Mixed Model (GLMM). Fuzzy grey points are original data points (color intensity increases from light grey to black when points overlap), while the grey band represents 95% confidence interval around the regression line.
