Effects of pCO(2) on physiology and skeletal mineralogy in a tidal pool coralline alga Corallina elongata
International audience Marine organisms inhabiting environments where pCO(2)/pH varies naturally are suggested to be relatively resilient to future ocean acidification. To test this hypothesis, the effect of elevated pCO(2) was investigated in the articulated coralline red alga Corallina elongata fr...

International audience Marine organisms inhabiting environments where pCO(2)/pH varies naturally are suggested to be relatively resilient to future ocean acidification.
