Table 5. OA effects on tropical benthic macroalgae.
A summary of findings to date from experiments exploring OA effects on growth, calcification, and photosynthesis in tropical benthic macroalgae. Only business-as-usual OA experiments (800–1200 µatm) are included. +, positive effect; −, negative effect; 0, no effect.
