Pollen Interference Between Rare and Common Species [PDF]
Ecology and Evolution, Volume 14, Issue 11, November 2024.In a multispecies greenhouse experiment, we performed hand pollination treatments between eight co‐occurring and co‐flowering plant species with varying rarity levels in Switzerland. We found that overall heterospecific pollen interference did not affect seed set nor seed number, used as proxies of recruitment, for neither common nor rare species.
