A quantitative genetic approach to assess the evolutionary potential of a coastal marine fish to ocean acidification
Assessing the potential of marine organisms to adapt genetically to increasing oceanic CO2 levels requires proxies such as heritability of fitness-related traits under ocean acidification (OA). We applied a quantitative genetic method to derive the first heritability estimate of survival under eleva...
