Figure 1From: Shotgun proteomics reveals physiological response to ocean acidification in Crassostrea gigasMean Vickers microhardness and fracture toughness of C. gigas shells (±95% C.I.) from 400, 1000, and 2800 μatm p CO 2 , tested within the outer 3 mm of the shell’s growing edge. Groups marked with different letters are significantly different (p <0.05; n =5-7 shells per treatment).Back to article page
