Health status of coral holobionts. (A) Measurements of photosynthetic efficiency Fv/Fm ratios in Pocillopora damicornis at 27 and 31 °C after treatment with strain SCSIO 13291 or FASW until the end of the experiment (n = 10). (B) Density of Symbiodiniaceae cells in coral tissue. Numbers are shown as the means ± standard deviations, which were calculated based on five coral nubbins. Asterisks indicate significant differences at P < 0.01
