Diel CO₂ cycles and parental effects have similar benefits to growth of a coral reef fish under ocean acidification.

ABSTRACT: Parental effects have been shown to buffer the negative effects of within-generation exposure to ocean acidification (OA) conditions on the offspring of shallow water marine organisms. However, it remains unknown if parental effects will be impacted by the presence of diel CO₂ cycles that are prevalent in many shallow water marine habitats. Here, we examined the effects that parental exposure to stable elevated (1000 µatm) and diel-cycling elevated (1000 ± 300 µatm) CO₂ had on the survival and growth of juvenile coral reef anemonefish, Amphiprion melanopus. Juvenile survival was unaffected by within-generation exposure to either elevated CO₂ treatment but was significantly increased (8%) by parental exposure to diel-cycling elevated CO₂. Within-g
