本地物种和引进物种之间的行为差异可能有助于某些物种的入侵。这包括物种水平上的差异，个体之间的一致变异（“个性”）和个体内变异（例如，行为可塑性）。在这里，我们调查了发生在莱茵河系统，其中三个是本地或归化（>100年的存在），而一个是最近的入侵者（Dikerogammarus villosus，<25年的存在）的四种不同的端足类动物的个体的游泳活动。在物种水平上，D.与三种非入侵物种相比，绒毛草没有表现出更高的平均游泳活动。然而，平均而言，非入侵物种在实验过程中可预测地改变了它们的行为（“平均行为可塑性”），而D。绒毛没有表现出任何一致的活性变化。在个体水平上，D. villosus表现出更大的个体间和个体内的活动水平的变化比所有非入侵物种。非入侵物种进一步显示出可塑性的显著个体差异，即这些物种的个体在如何随时间改变其活动方面始终存在差异。在D.villosutranslated的高个体内变异转化为缺乏一致的个体差异，在这个物种的可塑性。我们推测，高度可变和不可预测的模式，个体活动的变化inD.villosus可能有助于这种成功的入侵者，以科普新的环境条件下遇到的河流莱茵河系统。
Behavioral differences between native and introduced species may contribute to the invasiveness of certain species. This includes differences at the species level, consistent variation among individuals (“personality”) and within-individual variation (e.g., behavioral plasticity). Here, we investigated swimming activity of individuals from four different amphipod species occurring in the river Rhine system, three of which were native or naturalized (>100 years present) while one is a recent invader (Dikerogammarus villosus, <25 years present). At the species level,D. villosusdid not show higher average swimming activity than the three non-invasive species. However, the non-invasive species, on average, changed their behavior predictably over the course of the experiment (“average behavioral plasticity”), whileD. villosusdid not exhibit any consistent change in activity. At the individual level,D. villosusexhibited greater among- and within-individual variation in activity levels than all non-invasive species. The non-invasive species further showed significant individual differences in plasticity, that is, individuals of these species differed consistently in how they changed their activity over time. The high within-individual variation inD. villosustranslated into a lack of consistent individual differences in plasticity in this species. We hypothesize that the highly variable and unpredictable patterns of individual activity variation inD. villosusmight help this successful invader to cope with new environmental conditions encountered in the river Rhine system.
