Figure 5. Effects of urbanisation on overall pollination services (N=116) depending on four moderators; flower symmetry, reproductive success index, plant species origin, and pollinator group. Estimated mean effect sizes, 95% confidence intervals and sample size are shown. *p < 0.05, **p < 0.01, ***p < 0.001.
