In the Nature study you state that previous work has not determined the impact of acidification on the ability of individual species to calcify because they measured net calcification (that is, gross calcification minus dissolution) thus failing to disentangle the relative contributions of gross calcification (the amount of carbonate deposited by an animal over time) and dissolution rates.

Since you state that a decrease in net calcification could result from a decrease in gross calcification, an increase in dissolution rates, or both, you distinguish between these responses and get to the conclusion that the impact of ocean acidification on a creature's net calcification may be largely controlled by the status of its protective organic cover and that the net slowdown in skeletal growth under increased CO2 occurs not because these organisms are unable to calcify, but rather because their unprotected skeleton is dissolving faster.
