Rapid H2O2 release from Stylophora pistillata during feeding.
(a,b). Changes in H2O2 concentration before food was supplied (basal) and during feeding in ten individual coral fragments. Note the high variation between individuals (panels a and b have a different y-axis scale). Release of H2O2 from control untreated corals is shown in panel b as mean ± SE (n = 6). (c) Summary of all experiments presented as mean ± SE of the change in H2O2 with time relative to the maximal concentration in each experiment.
