Sea urchin response to rising pCO2 shows ocean acidification may fundamentally alter the chemistry of marine skeletons
Ocean acidification caused by an increase in pCO2 is expected to drastically affect marine ecosystem composition, yet there is much uncertainty about the mechanisms through which ecosystems may be affected. Here we studied sea urchins that are common and important grazers in the Mediterranean (Parac...
