Fig 7. The reduction in the quantum yield of F. scutaria zooxanthellae due to M. capitata egg chemical fractions.

Fig 7

The zooxanthellae from two individuals were divided up into 5 sub-samples and exposed to 30 µl of FSW, dimethyl sulfoxide (DMSO), frozen crushed M. capitata eggs, water fraction, butanol fraction (BuOH) or ethyl acetate fraction (EtOAc). The quantum yield of FSW and DMSO, were not different (P>0.05, ANOVA, Dunnett’s Multiple Comparison Test). But adding 30 µl of each of the chemical fractions or frozen eggs caused a reduction of 25 to 44% in the quantum yield over 40 min over the FSW values (P> 0.05, ANOVA, Dunnett’s Multiple Comparison Test). Bars with different letters were (P < 0.05). Bars indicate SEM.
