I study ecological aspects of sexual dimorphism. Using phylogenetic comparative methods, I am testing alternative hypotheses for the role of sexual dimorphism in a vertebrate radiation, the amphibia. Sexual dimorphism may be an important component of adaptive radiation if sexually dimorphic species occupy wider niches than monomorphic species, or if sex-specific selection facilitates diversification. In a similar vein but different scale, I use field experiments to examine how community structure may differentially affect male and female newts. Future work may include experiments examining sex-specific local adaptation in newts, and theory examining the evolution of sexual dimorphism in uncertain environments.
