Effect of carbonate chemistry manipulations on calcification, respiration, and excretion of a Mediterranean pteropod
International audience Although shelled pteropods are expected to be particularly sensitive to ocean acidification, the few available studies have mostly focused on polar species and have not allowed determining which parameter of the carbonate system controls their calcification. Specimens of the t...
