Abstract excerpt
I address how floral complexity influences geitonogamous self-pollination through manipulation of pollinator behavior in Salvia nipponica. The pivoting stamens of S. nipponica hinder nectar-collecting bumblebees from crawling into flowers, increasing the probing time per flower. I predicted that longer probing times would reduce the relative cost of moving between plants, causing bees to leave plants earlier. To...
