Ocean acidification is predicted to have detrimental effects on many marine organisms and ecological processes. Despite growing evidence for direct impacts specific species, few studies simultaneously considered the of ocean individuals (e.g. consequences energy budgets resource partitioning) population level demographic Here we show that increases energetic demands gastropods resulting in altered allocation, i.e. reduced shell size but increased body mass. When scaled up level, long-term exposure demography, with a reduction proportion females genetic signatures variance reproductive success among individuals. Such enhances levels short-term drift which inhibit adaptation. Our study indicates even against background high gene flow, driving individual- population-level changes will impact eco-evolutionary trajectories.
