1. Rare plant species often suffer less damage than common species because of positive density-dependent herbivory, and it has been suggested that this “rare species advantage” fosters plant species coexistence. However, it is unknown whether rare species have an advantage when pollination interactions are also considered. 2. We hypothesized that a “positive density-dependent pollination success” across plant species would result in common plants experiencing higher seed set rates compared to rare species, and that positive...
