Phenotypic plasticity of coralline algae in a High CO2world
It is important to understand how marine calcifying organisms may acclimatize to ocean acidification to assess their survival over the coming century. We cultured the cold water coralline algae, Lithothamnion glaciale, under elevated pCO2 (408, 566, 770, and 1024 μatm) for 10 months. The results sho...

It is important to understand how marine calcifying organisms may acclimatize to ocean acidification to assess their survival over the coming century.
