Short summary
Photosynthetic activity and/or nitrate assimilation by the macroalgae Ulva buffered carbonate chemistry and yielded enhanced growth of bivalves by mitigating the harmful effects of elevated CO2 levels. This benefit was not limited to acidified conditions, as evidenced by increased bivalve growth in the presence of Ulva within ambient CO2 treatments. The ability of macroalgae to buffer carbonate chemistry may be increasingly important for calcifying organisms vulnerable to ocean acidification.
