The role of commercial harbours as sink and source habitats for non-indigenous species (NIS) and the role of recreational boating for their secondary spread were investigated by analysing the fouling community of five Italian harbours and five marinas in the western Mediterranean Sea. It was first hypothesised that NIS assemblages in the recreational marinas were subsets of those occurring in commercial harbours. However, the data did not consistently support this hypothesis: the NIS pools of some marinas significantly diverged from harbours even belonging to the same coastal stretches, including NIS occurring only in marinas. This study confirms harbours as hotspots for marine NIS, but also reveals that numbers of NIS in some marinas is higher than expected, suggesting that recreational vessels effectively facilitate NIS spread. It is recommended that this vector of NIS introduction is taken into account in the future planning of sustainable development of maritime tourism in Europe.
通过分析地中海西部五个意大利港口和五个游艇码头的污损生物群落，研究了商业港口作为非本土物种（NIS）的汇和源栖息地的作用以及休闲划船对其二次传播的作用。最初假设休闲游艇码头中的非本土物种组合是商业港口中出现的物种组合的子集。然而，数据并不一致支持这一假设：一些游艇码头的非本土物种库与港口明显不同，甚至属于同一海岸段的港口也如此，包括仅在游艇码头出现的非本土物种。本研究证实港口是海洋非本土物种的热点地区，但也表明一些游艇码头的非本土物种数量高于预期，这表明休闲船只有效地促进了非本土物种的传播。建议在欧洲海上旅游可持续发展的未来规划中考虑这种非本土物种引入的途径。
