Seagrasses and Marine Macroalgae in a CO2-Enriched World
Koch, M, Bowes, G., Ross, C. and Zhang, X.-H. 2013. Climate change and ocean acidification effects on seagrasses and marine macroalgae. Global Change Biology 19: 103-132.
The four researchers determined that their "literature review of >100 species revealed that marine macro-autotroph photosynthesis is overwhelmingly C3 (>=85%) with most species capable of utilizing HCO3-," and that "most are not saturated at current ocean DIC," which results lead them to conclude that "photosynthetic and growth rates of marine macro-autotrophs are likely to increase under elevated CO2 similar to terrestrial C3 species." Furthermore, while noting that "the photosynthesis of the majority of the species examined was not saturated at the current levels of DIC in the ocean and responded to an increase in CO2," Koch et al. write that seagrasses and many marine macroalgae have the potential to respond positively, in terms of photosynthesis and growth, under elevated ocean CO2 and OA.
