  abstract = {{U}nderstanding how environmental change affects genetic variances and covariances of reproductive traits is key to formulate firm predictions on evolutionary responses. {T}his is particularly true for sex-specific variance in reproductive success, which has been argued to affect how populations can adapt to environmental change. {O}ur current knowledge on the impact of environmental stress on sex-specific genetic architecture of fitness components is still limited and restricted to separate-sexed organisms. {H}owever, hermaphroditism is widespread across animals and may entail interesting peculiarities with respect to genetic constraints imposed on the evolution of male and female reproduction. {W}e explored how food restriction affects the genetic variance-covariance ({G}) matrix of body size and reproductive success of the simultaneously hermaphroditic freshwater snail {P}hysa acuta. {O}ur results provide strong evidence that the imposed environmental stress elevated the opportunity for selection in both sex functions. {H}owever, the {G}-matrix remained largely stable across the tested food treatments. {I}mportantly, our results provide no support for cross-sex genetic correlations suggesting no strong evolutionary coupling of male and female reproductive traits. {W}e discuss potential implications for the adaptation to changing environments and highlight the need for more quantitative genetic studies on male and female fitness components in simultaneous hermaphrodites.},
