A Differentially expressed genes in response to heat shock (HS) and mating (R); 137 genes responded to both treatments, which was more than expected by chance. B Of these genes, all but three showed antagonistic responses to the two treatments, signifying a trade-off between investment in reproduction and maintenance under heat stress. C GO term enrichments for genes upregulated (+) or downregulated (−) in response to mating (R) and heat stress (HS), as well as for the overlapping antagonistic genes. D The expression of the 134 antagonistic genes in the experimental evolution lines and ancestors indicate a clear increase in allocation towards cellular maintenance at the cost of reduced reproduction when beetles were reared at 35 °C (the thermal regime of hot-adapted lines). However, there were no consistent differences in expression between ancestors (black) and the cold (blue) or hot (red) evolution regime.
