    C M Caruso
    Department of Integrative Biology, University of Guelph, Guelph, ON, Canada
    J Evol Biol 21:1514-23. 2008
    ..We did not detect significant stabilizing selection on traits of either sex morph. Our results provide little support for the hypothesis that sexual dimorphism in gynodioecious plants evolved in response to sex morph-specific selection...
