Optimality, plasticity and selective regime in fig wasp sex ratios

  title={Optimality, plasticity and selective regime in fig wasp sex ratios},
  author={E. Herre},
In thirteen species of fig-pollinating wasps the sex ratios of broods with one or two foundress mothers show qualitative agreement with the optimal sex ratios predicted by local mate competition theory. The deviations from these predictions are not random: for a given number of foundresses, the deviations are least in the wasp species that naturally encounter that number of foundresses most frequently. Furthermore, the difference in sex ratio between broods with one and broods with two… CONTINUE READING
