  • Descrição: We tested the hypothesis that surface wettability does not alter the positive effect of natural biofilms on larval attachment in the barnacle Balanus amphitrite. We also answered the question: Does substratum-biofilm interaction affect the larval choice in barnacle? We developed natural multi-species biofilms of different ages on both high (glass) and low (polystyrene) wettability surfaces at mid-intertidal height (native habitat of B. amphitrite). Attachment choice of both young (0-d-old) and old (6-d-old) larvae to biofilms was determined using still water choice bioassay. Irrespective of larval age, cyprid preferred to attach to un-filmed glass than to un-filmed polystyrene. In contrast to aged larvae, young larvae preferred old (6-d-old) biofilms on polystyrene to young (3-d-old) biofilms on glass. In this study, we were also able to examine the interaction between surface wettability, biofilms and larval attachment, by characterizing bacterial community composition in biofilms. Bacterial community composition showed significant differences between biofilms of different ages. Old biofilms positively influenced larval attachment, irrespective of the type of substrata, thereby supporting the hypothesis that surface wettability does not alter the positive effect of natural biofilms on larval attachment.
