Sexual selection and population spatial structure interact to shape sex-specific evolutionary responses in physiology

Different selection pressures acting on females and males arising from sexual selection and sexual conflict may lead to sex-specific phenotypic expression of physiological traits. Importantly, sexual selection is affected by ecological and demographic factors. We explored whether population spatial structure modulates the effect of sexual selection on male and female standard metabolic rates and oxidative stress. For this purpose, we used selection lines of the seed beetle Callosobruchus maculatus subjected to divergent evolutionary regimes in the intensity of sexual selection (high vs. low, in polygamous vs. enforced monogamous populations, respectively) and the presence of metapopulation structure (absent vs. present). We found that the evolutionary treatments impacted physiological traits in a complex way. While in the selection regimes simulating metapopulation structure (i.e., divided populations) both sexes had similar metabolic rates, in undivided (unstructured) populations males..., , # Data from: Sexual selection and population spatial structure interact to shape sex-specific evolutionary responses in physiology

## Description of the data and file structure

We explore whether the interaction between population spatial structure and sexual selection shapes key male and female physiological traits in the seed beetle Callosobruchus maculatus. To do that, we used experimental populations subjected to different intensities of sexual selection/conflict (monogamy vs polygamy), and different levels of population spatial structure (population division with connectivity – i.e., metapopulation structure – vs absence of population spatial division.

Among the physiological traits, we measured metabolic rates, oxidative stress (TBARS) and the antioxidant capacity (SOD). 

The sample size was:
