  text: Sexual dimorphism in resource allocation is expected to change during the
    life cycle of dioecious plants because of temporal differences between the sexes
    in reproductive investment. Given the potential for sex-specific differences in
    reproductive costs, resource availability may contribute to variation in reproductive
    allocation in females and males. Here, we used Rumex hastatulus, a dioecious,
    wind-pollinated annual plant, to investigate whether sexual dimorphism varies
    with life-history stage and nutrient availability, and determine whether allocation
    patterns differ depending on reproductive commitment. To examine if the costs
    of reproduction varied between the sexes, reproduction was either allowed or prevented
    through bud removal, and biomass allocation was measured at maturity. In a second
    experiment to assess variation in sexual dimorphism across the life cycle, and
    whether this varied with resource availability, plants were grown in high and
    low nutrients and allocation to roots, aboveground vegetative growth and reproduction
    were measured at three developmental stages. Males prevented from reproducing
    compensated with increased above- and belowground allocation to a much larger
    degree than females, suggesting that male reproductive costs reduce vegetative
    growth. The proportional allocation to roots, reproductive structures and aboveground
    vegetative growth varied between the sexes and among life-cycle stages, but not
    with nutrient treatment. Females allocated proportionally more resources to roots
    than males at peak flowering, but this pattern was reversed at reproductive maturity
    under low-nutrient conditions. Our study illustrates the importance of temporal
    dynamics in sex-specific resource allocation and provides support for high male
    reproductive costs in wind-pollinated plants.
