摘要: For pollinators to exert selection on floral traits, they must be able detect and respond differences in morphologies. I examined foraging preferences by the bee Apis mellifera (Apidae) visiting naturally occurring flowers of Mimulus guttatus (Scrophulariaceae). The results indicate that A. preferentially selects larger M. their bouts. Since flower size have previously been shown a significant heritable component, suggest has potential an important selective force morphology guttatus.
