Effect of monospecific bacterial biofilm on mean settlement of the sessile marine invertebrates: Pocillopora damicornis and Amphibalanus amphitrite

The increasing trend of natural coastline alternation in coastal cities like Singapore calls for a deeper understanding of its impact on biodiversity on seawalls. This study aimed to evaluate the effectiveness of biofilms on the settlement of two widely studied marine invertebrates, Pocillopora dami...
