A comparison of MgCO3 in individual sub-components of major skeletal structures of the common temperate sea urchin Paracentrotus lividus
The major skeletal structures (test, spines, Aristotle's lantern) of a common regular sea urchin Paracentrotus lividus were analyzed for Mg-calcite composition to determine their relative vulnerability to ocean acidification. Percentage of MgCO3 in the test and several sub-components of the Ari...
