Much interest has focused on the role of microbial layers--biofilms--in stimulating attachment of invertebrates and algae to submerged marine surfaces. We investigated the influence of biofilms on the adhesion strength of settling invertebrates. Larvae of four species of biofouling invertebrate were allowed to attach to test surfaces that were either clean or coated with a natural biofilm. Measuring larval removal under precisely controlled flow forces, we found that biofilms significantly increased adhesion strength in the ascidian Phallusia nigra, the polychaete tubeworm Hydroides elegans, and the barnacle Balanus amphitrite at one or more developmental stages. Attachment strength in a fourth species, the bryozoan Bugula neritina, was neither facilitated nor inhibited by the presence of a biofilm. These results suggest that adhesive strength and perhaps composition may vary across different invertebrate taxa at various recruitment stages, and mark a new path of inquiry for biofouling research.
微生物层——生物膜——在刺激无脊椎动物和藻类附着于水下海洋表面方面所起的作用已备受关注。我们研究了生物膜对定居无脊椎动物附着强度的影响。让四种生物污损无脊椎动物的幼虫附着在清洁的或涂有天然生物膜的测试表面上。通过在精确控制的流动力下测量幼虫的移除情况，我们发现生物膜在一个或多个发育阶段显著提高了海鞘黑海鞘、多毛纲管栖蠕虫优美盘管虫和藤壶白脊藤壶的附着强度。在第四种生物苔藓虫内肛苔藓虫中，生物膜的存在既没有促进也没有抑制附着强度。这些结果表明，在不同的招募阶段，不同无脊椎动物类群的附着强度甚至可能还有组成成分可能会有所不同，这为生物污损研究开辟了一条新的探究途径。
