A large body of ecological theory predicts that non-indigenous species (NIS) are successful invaders if their niches overlap little with native taxa. Native–non-indigenous trait dissimilarity, however, may also be observed if NIS have outcompeted ecologically similar native species. Discriminating these scenarios is essential for assessing invasion impacts but requires baseline assemblage data that are frequently unavailable. We overcome this impediment by analysing death assemblages – identifiable organism remains in the seafloor – which are natural community archives. Focusing on molluscs from the heavily invaded Eastern Mediterranean, we gain insights into the contentious role of competitive displacement by NIS as the primary driver of the massive regional declines of native populations, and their potential to alter ecosystem functioning.

东地中海的非本土软体动物具有独特的特征,不能取代历史生态系统功能

大量生态理论预测,如果非本地物种 (NIS) 的生态位与本地分类群几乎没有重叠,那么它们就是成功的入侵者。然而,如果 NIS 在生态上超过了相似的本地物种,也可能观察到本地与非本地特性的差异。区分这些情景对于评估入侵影响至关重要,但需要经常无法获得的基线组合数据。我们通过分析死亡组合(海底中可识别的有机体)来克服这一障碍,这些组合是自然社区档案。关注来自严重入侵的东地中海的软体动物,我们深入了解了 NIS 的竞争性置换作为本地人口大规模区域下降的主要驱动因素的有争议的作用,以及它们改变生态系统功能的潜力。
