Selection on flower color from herbivores, pollinators, and other agents: Results from a long- term field experiment

Background/Question/Methods

Most studies of selection on traits explore the effects of only a single agent; however, most traits are under selection from a variety of agents or interactiors in complex natural communities.  In field experiments,  I explore the importance of herbivory, pollination and other agents associated with variation among years, as selective forces on a flower color polymorphism in wild radish, Raphanus sativus. 
Results/Conclusions

Using ten years of experimental herbivore removals in the field, combined with a few years of experimental hand-pollinations and descriptive demographic data on seedling and adult color frequencies,  I evaluate the relative importance of these sources of selection on flower color.
