Research
I am
interested in the evolutionary
cause and maintenance of sex
differences. While sexual dimorphism is almost exclusively
attributed to sexual selection, the role of natural selection remains
poorly understood. Therefore, I examine the potential role of
natural selection in the evolution of color variation in Hawaiian Megalagrion
damselflies (Odonata: Coenagrionidae). Although
most species in this genus exhibit sexual dimorphism in color (red
males and green females) some species contain a female-limited
dimorphism in which the male color is expressed by some
females. Such female-limited dimorphisms are common in
odonates, but the adaptive significance remains unknown. By
looking at variation in selection of a female-limited dimorphism and by
examining patterns of color and ecological niche type in the Megalagrion
damselfly phylogeny, it is possible to evaluate the potential
significance of natural selection in the evolution of sexual dimorphism.
