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.
