Selection by Pollinators and Herbivores on Attraction and Defense

Preview

Interactions between plants, their herbivores, and their pollinators are thought to have led to the diversification of both plants and insects. Historically, studies of plant–herbivore and plant–pollinator interactions have occurred independently. Research at both micro- and macroevolutionary levels has focused on the evolution of plant resistance in the context of herbivory, and on floral traits in the context of pollination. This chapter explores the role of insects on the evolution of attraction and defense. It reviews the literature on selection by pollinators and herbivores on resistance and attractive traits, with the goal of highlighting the pathways by which pollinators may affect the evolution of plant resistance, and herbivores may affect the evolution of floral attractive traits. The chapter also considers selection by pollinators on plant resistance, selection by herbivores on floral traits, whether resistance and attraction traits are independent, whether herbivores and pollinators are independent, and the link between abiotic factors and geographic variation.
