Differential responses to ocean acidification between populations of Balanophyllia eleganscorals from high and low upwelling environments
Abstract Ocean acidification (OA), the global decrease in surface water pH from absorption of anthropogenic CO 2 , may put many marine taxa at risk. However, populations that experience extreme localized conditions, and are adapted to these conditions predicted in the global ocean in 2,100, may be m...
