Humans are altering the environment at an unprecedented rate. Although behavioural plasticity has allowed many species to respond by shifting their ranges to more favourable conditions, these rapid environmental changes may cause 'evolutionary traps', whereby animals mistakenly prefer resources that reduce their fitness. The role of evolutionary traps in influencing the fitness consequences of range shifts remains largely unexplored. Here, we review these interactions by considering how climate change may trigger maladaptive developmental pathways or increase the probability of animals encountering traps. We highlight how traps could selectively remove some phenotypes and compromise population persistence. We conclude by highlighting emerging areas of research that would improve our understanding of when interactions between evolutionary traps and range shifts are likely to be most detrimental to animals.
人类正在以前所未有的速度改变环境。尽管行为可塑性使许多物种能够通过将活动范围转移到更适宜的条件来做出反应，但这些快速的环境变化可能会导致“进化陷阱”，即动物错误地偏好那些会降低其适应性的资源。进化陷阱在影响范围转移的适应性后果方面所起的作用在很大程度上仍未得到探索。在这里，我们通过考虑气候变化如何引发适应不良的发育途径或增加动物遇到陷阱的可能性来审视这些相互作用。我们强调陷阱如何能够选择性地淘汰某些表型并危及种群的持续存在。我们最后着重指出新兴的研究领域，这些领域将增进我们对进化陷阱与范围转移之间的相互作用何时可能对动物最为不利的理解。
