To prevent the settlement and/or the growth of fouling organisms (i.e. bacteria, fungi or microalgae), benthic sessile species have developed various defense mechanisms among which the production of chemical molecules. While studies have mostly focused on the release of chemical compounds by single species, there exist limited data on multi-species assemblages. We used an integrative approach to explore the potential interactive effects of distinct assemblages of two corals species and one giant clam species on biofouling appearance and composition. Remarkably, we found distinct biofouling communities suggesting the importance of benthic sessile assemblages in biofouling control. Moreover, the assemblage of 3 species led to an inhibition of biofouling, likely through a complex of secondary metabolites. Our results highlight that through their different effect on their near environment, species assemblages might be of upmost importance for their survival and therefore, should now be taken into account for sustainable management of coral reefs.
为了防止附着生物（即细菌、真菌或微藻）的定殖和/或生长，底栖固着生物发展出了各种防御机制，其中包括化学分子的产生。虽然研究主要集中在单一物种释放化学化合物上，但关于多物种组合的数据有限。我们采用综合方法来探索两种珊瑚物种和一种巨蛤物种的不同组合对生物污垢出现和组成的潜在相互作用影响。值得注意的是，我们发现了不同的生物污垢群落，这表明底栖固着生物组合在生物污垢控制中的重要性。此外，3 种物种的组合导致生物污垢的抑制，可能是通过次生代谢物的复杂作用。我们的结果表明，通过对其近环境的不同影响，物种组合可能对其生存至关重要，因此，现在应该考虑将其纳入珊瑚礁的可持续管理中。
