Biofouling on ships has been linked to the spread of invasive species, which has been identified as one of the current primary threats to the environment. Previous research on antifouling coatings suggested that the quantity of fouling, as well as community composition, on biocidal coatings was modified by prior fouling settlement. The experiment reported in this paper was designed to determine how preconditioning affected the rate and composition of subsequent fouling on transplanted silicone coatings. A series of 10 × 20 cm panels coated with Intersleek 700 or DC3140 were placed at three locations in Florida (Ponce Inlet, Sebastian Inlet, and Port of Miami), which were characterized by distinct fouling communities. Panels were immersed for four months, cleaned, and reciprocally transplanted among the three sites. Fouling community composition and coverage were characterized at bimonthly intervals both before and after transplantation. The original fouling community affected the subsequent fouling composition and recolonization by tunicates, sea anemones, barnacles, sponges, hydroids, and arborescent bryozoans. The community-level effects were short-term, lasting 2-4 months, but specific responses lasted up to 14 months post-transplant.
船舶生物污损与入侵物种的传播有关，入侵物种已被确定为当前对环境的主要威胁之一。先前关于防污涂层的研究表明，杀生涂层上的污损数量以及群落组成会因先前的污损沉降而改变。本文报道的实验旨在确定预处理如何影响移植的有机硅涂层上后续污损的速率和组成。一系列涂有Intersleek 700或DC3140的10×20厘米面板被放置在佛罗里达州的三个地点（庞塞河口、塞巴斯蒂安河口和迈阿密港），这些地点具有不同的污损群落特征。面板浸泡四个月后进行清洗，并在三个地点之间相互移植。在移植前后每两个月对污损群落组成和覆盖率进行一次表征。原始污损群落影响了后续的污损组成以及被囊动物、海葵、藤壶、海绵、水螅体和树状苔藓虫的重新定殖。群落水平的影响是短期的，持续2至4个月，但特定反应在移植后可持续长达14个月。
