虽然入侵物种对许多分类群的生态影响已得到证实，但非本地个体的行为变异（即个性）对这些影响的潜在影响在很大程度上被忽视了。尽管最近的研究表明，从本质上讲，生物入侵的前三个阶段（即运输、建立和传播）可能会导致人群出现人格偏见。淡水生态系统为研究这一问题提供了独特的机会，特别是因为非本地物种的生态影响已被广泛记录，并且因为使用淡水模型物种广泛研究了动物个性。在这里，我们的目标是就动物个性对跨生物组织层面的淡水非本地物种的生态影响的潜在影响提出一些观点。在个体层面，人格类型已被证明会影响个体的生理、新陈代谢、生活史特征和健康。我们利用这些影响来讨论它们随后如何影响入侵人口，进而影响受灾社区。我们还讨论了这些如何转化为食物网结构和被入侵生态系统功能的变化。最后我们讨论了这些观点如何与入侵物种的管理相互作用。
While the ecological impacts of invasive species have been demonstrated for many taxonomic groups, the potential effects of behavioural variation among non-native individuals (i.e. personality) on these impacts have been largely overlooked. This is despite the fact that recent studies have demonstrated that, by nature, the three first stages of biological invasions (i.e. transport, establishment and spread) can lead to personality-biased populations. Freshwater ecosystems provide a unique opportunity to investigate this issue, notably because the ecological impacts of non-native species have been extensively documented and because animal personality has been widely studied using freshwater model species. Here, we aim at developing some perspectives on the potential effects of animal personality on the ecological impacts of freshwater non-native species across levels of biological organizations. At the individual level, personality types have been demonstrated to affect the physiology, metabolism, life history traits and fitness of individuals. We used these effects to discuss how they could subsequently impact invaded populations and, in turn, recipient communities. We also discussed how these might translate into changes in the structure of food webs and the functioning of invaded ecosystems. Finally we discussed how these perspectives could interact with the management of invasive species.
