| Outline of Final Research Achievements |
In this study, I tested if one plant species can facilitate pollinator visits to subsequently-flowering species with similar floral traits even if their flowering overlap for only a short period. I created patches of potted snapdragons near the wild populations of jewelweeds as a newly-flowering species at the end of the flowering period of jewelweeds. The flower color of snapdragons in a patch was either orange or deep-pink which is similar to the color of jewelweed flower. As a result of observation using interval timer shooting, deep-pink snapdragon flowers received more bumblebee visits than the orange flowers. This result suggests that a plant species can exert a positive impact on the reproductive success of subsequently-flowering species through pollinators’ memory, and such relationship is plausible if those species have similar floral traits. Such interspecific facilitation may act as a mechanism of coexistence of different flower species sharing pollinators in a community.
