Fig. 2From: Meta-analysis reveals severe pollen limitation for the flowering plants growing in East Himalaya-Hengduan Mountains regionDistribution of pollination limitation of collected plants in the East Himalaya-Hengduan Mountains. The black circles represent the species that were not pollination limited (the effect size is negative or the 95% confidence interval overlap zero), and the white circles represent pollination-limited species (the effect size is positive and the 95% confidence interval did not overlap zero)Back to article page
