Table 3 Impacts of high pCO₂ on gene expression and calcification in marine invertebrate taxa. ‘Calcification genes’ is a broad term that encompasses any calcification or biomineralization processes as defined independently in each study, which includes acid-base regulation in some studies and not in others. Arrows denote the direction of the response. In instances with both arrows, this reflects either overall differential expression (genes being both up and down regulated), or conflicting results across studies or life-history stages. Dashes indicate a non-significant response. In studies where pCO₂ was not calculated (or only calculated in some studies), pH values are given. It should be noted that calcification and gene expression measurements for a particular species may be confined to separate independent studies
