Figure 6. Influence of sponge reproductive status on the bioactivity.

Figure 6

a) Variation of Oscarella balibaloi bioactivity (EC50 in µg.mL−1) according to reproductive stage. The effect of significance is given by Kruskal-Wallis test: H KW(2;109)  =  31.48, p<0.001. b) Variation of Oscarella balibaloi bioactivity (EC50 in µg.mL−1) according to sponge sexe. The effect of significance is given by Kruskal-Wallis test: H KW(2;109)  =  31.44, p<0.0001. c) Correlation between Oscarella balibaloi bioactivity (EC50 in µg.mL−1) and its reproductive effort (%): R = 0.49, p = 0.0008. Boxes represent Mean ± 0.95 SE and vertical bars Mean ± 0.95 Confidence Interval.
