Webster et al. (2013)

Larval settlement and metamorphosis of eight-day old staghorn coral (Acropora millepora) larvae after 18 hours exposure to reduced pH conditions. Settlement and metamorphis were aided by the presence of a crustose coralline algae (Hydrolithon onkodes) that had been subject to idential reduced pH conditions for 42 days prior. Temperature was maintained at approximately 27C.

Larval settlement and metamorphosis of eight-day old staghorn coral (Acropora millepora) larvae after 18 hours exposure to reduced pH conditions. Settlement and metamorphis were aided by the presence of a crustose coralline algae (Hydrolithon onkodes) that had been subject to normal pH conditions for 42 days prior. Temperature was maintained at approximately 27C.

Larval settlement and metamorphosis of eight-day old staghorn coral (Acropora millepora) larvae after 18 hours exposure to reduced pH conditions. Settlement and metamorphis were aided by the addition of 30 l of a crustose coralline algae extract (Hydrolithon onkodes) given after the first 24 hours of pH exposure, which extract induces sub-maximal metamorphosis. Temperature was maintained at approximately 27C.
