Ocean acidification reduces coral recruitment by disrupting intimate larval‐algal settlement interactions
Ecology Letters (2012) 15 : 338–346 Abstract Successful recruitment in shallow reef ecosystems often involves specific cues that connect planktonic invertebrate larvae with particular crustose coralline algae (CCA) during settlement. While ocean acidification (OA) can reduce larval settlement and th...
