Marine litter, such as plastic bags, bottles, fabrics, or fishing gear, serve as a shelter for many marine organisms that are likely to colonize artificial substrata. Such assemblages can potentially turn marine litter into vectors of alien invasive species (AIS). Here, we report the abundance and diversity of macroinvertebrates inhabiting marine litter in Peruvian beaches. Results indicate that most of the fouled items found came from land-based sources (81.5%) and Bivalvia was the most abundant class (53.5%), mainly composed of the mussel Semimytilus algosus. No significant differences were found in the abundance and diversity of macroinvertebrates (class level) among sampling sites or sources of litter. Polypropylene and low-density polyethylene items were most frequently found with fouled biota. Although none of the identified species were non-native to the coast of Peru, we discuss marine litter as a potential source of AIS in this region.
海洋垃圾，如塑料袋、瓶子、织物或渔具，为许多可能在人工基质上定殖的海洋生物提供了庇护所。这些生物群落可能会使海洋垃圾成为外来入侵物种（AIS）的载体。在这里，我们报告了栖息在秘鲁海滩上的海洋垃圾中的大型无脊椎动物的丰度和多样性。结果表明，发现的大部分受污染物品来自陆地来源（81.5%），双壳类动物是最丰富的类群（53.5%），主要由贻贝 Semimytilus algosus 组成。在采样地点或垃圾来源之间，大型无脊椎动物（类水平）的丰度和多样性没有显著差异。最常发现的受污染生物是带有聚丙烯和低密度聚乙烯物品的生物。尽管鉴定出的物种没有一种是非秘鲁海岸的本地物种，但我们讨论了海洋垃圾作为该地区外来入侵物种的潜在来源。
