Abstract: Variation in sexual selection among populations and species has been suggested as an explanation for patterns of sexual size dimorphism. The strength of sexual selection on body size and other male traits was studied in a population of Sceloporus virgatus, a lizard in which females have a larger average size than males. Sexual selection on male size was found to be weak, with only the very smallest males having a mating disadvantage. This study provides tentative support for a sexual selection-fecundity selection trade off as an explanation for sexual size dimorphism in the genus Sceloporus, though further studies of the relationship between body size and reproductive success are needed
