Understanding how environmental change affects genetic variances and covariances of reproductive traits is key to formulate firm predictions on evolutionary responses. This is particularly true for sex-specific variance in reproductive success, which has been argued to affect how populations can adapt to environmental change. Our current knowledge on the impact of environmental stress on sex-specific genetic architecture of fitness components is partial and only on separate-sexed organisms lacking for hermaphroditic ones. We proposed thus to study environmental effects on male and female reproduction in simultaneous hermaphrodites.
