The evolution of separate sexes is widespread in flowering plants. Gynodioecy, which is the coexistence of female and hermaphroditic individuals, is often considered a transitional stage in the evolutionary pathway from hermaphrodism to separate sexes, yet the precise genetic and ecological mechanisms remain unclear. Insects mediate a variety of ecological processes in plants that have consequences on plant survival, reproduction, and evolution. Meadow checkermallow (Sidalcea campestris) is a gynodioecious species endemic to Oregon’s Willamette Valley that is a critical resource to native prairie pollinators and suffers high rates of pre-dispersal seed predation by a specialist weevil (Macrorhoptus sidalceae). In this presentation, Oregon State University PhD student Brooklyn Richards will be presenting her research on plant-insect interactions that potentially influence the mating system dynamics of S. campestris.
