An ultraviolet floral polymorphism associated with life history drives pollinator discrimination in <i>Mimulus guttatus</i>

Abstract

We describe a widespread UV polymorphism associated with life history divergence within Mimulus guttatus. UV pattern influences pollinator visitation and should be considered when estimating reproductive barriers between life history ecotypes. This work develops a new system to investigate the ecology and evolution of UV floral patterning in a species with extensive genomic resources.
