Research Description

What selection pressures lead to variation between sexes and between species, and what maintains that variation? To study this, my lab investigates selection pressure through the social environment (mate choice and species recognition) and the ecological environment (viability). Our current research focuses on the evolution of color and shape variation of species in two damselfly genera, Megalagrion (an endemic Hawaiian radiation) and Calopteryx (of the mainland US and Canada). These systems contain extensive phenotypic color variation geographically and between species and sexes, have interesting courtship behaviors, and are sensitive to habitat alteration. Ultimately, we aim help understand the roles of ecological and sexual selection in shaping variation, speciation, and evolutionary responses to climate change.
