  text: Understanding the mechanisms causing phenotypic differences between females
    and males has long fascinated evolutionary biologists. An extensive literature
    exists on animal sexual dimorphism but less is known about sex differences in
    plants, particularly the extent of geographical variation in sexual dimorphism
    and its life-cycle dynamics. Here, we investigate patterns of genetically-based
    sexual dimorphism in vegetative and reproductive traits of a wind-pollinated dioecious
    plant, Rumex hastatulus, across three life-cycle stages using open-pollinated
    families from 30 populations spanning the geographic range and chromosomal variation
    (XY and XY1Y2) of the species. The direction and degree of sexual dimorphism was
    highly variable among populations and life-cycle stages. Sex-specific differences
    in reproductive function explained a significant amount of temporal change in
    sexual dimorphism. For several traits, geographical variation in sexual dimorphism
    was associated with bioclimatic parameters, likely due to the differential responses
    of the sexes to climate. We found no systematic differences in sexual dimorphism
    between chromosome races. Sex-specific trait differences in dioecious plants largely
    result from a balance between sexual and natural selection on resource allocation.
    Our results indicate that abiotic factors associated with geographical context
    also play a role in modifying sexual dimorphism during the plant life cycle.
