A growing body of literature has documented myriad effects of human activities on animal behaviour, yet the ultimate ecological consequences of these behavioural shifts remain largely uninvestigated. While it is understood that, in the absence of humans, variation in animal behaviour can have cascading effects on species interactions, community structure and ecosystem function, we know little about whether the type or magnitude of human‐induced behavioural shifts translate into detectable ecological change. Here we synthesise empirical literature and theory to create a novel framework for examining the range of behaviourally mediated pathways through which human activities may affect different ecosystem functions. We highlight the few empirical studies that show the potential realisation of some of these pathways, but also identify numerous factors that can dampen or prevent ultimate ecosystem consequences. Without a deeper understanding of these pathways, we risk wasting valuable resources on mitigating behavioural effects with little ecological relevance, or conversely mismanaging situations in which behavioural effects do drive ecosystem change. The framework presented here can be used to anticipate the nature and likelihood of ecological outcomes and prioritise management among widespread human‐induced behavioural shifts, while also suggesting key priorities for future research linking humans, animal behaviour and ecology.

人为引起的动物行为变化的生态影响。

越来越多的文献记录了人类活动对动物行为的多种影响，但是这些行为转变的最终生态后果在很大程度上尚未得到研究。虽然可以理解的是，在没有人类的情况下，动物行为的变化会对物种相互作用，群落结构和生态系统功能产生连锁反应，但我们对人为行为转变的类型或程度是否转化为可检测到的生态变化知之甚少。在这里，我们综合了经验文献和理论，以创建一个新颖的框架来研究人类活动可能影响不同生态系统功能的行为介导途径的范围。我们重点介绍了一些经验研究，这些研究表明了其中某些途径的潜在实现，而且还要确定许多可以抑制或防止最终生态系统后果的因素。如果对这些途径没有更深入的了解，我们可能会浪费宝贵的资源来缓解行为影响，而这些行为几乎没有生态相关性，或者相反地，如果行为管理确实会推动生态系统变化，管理不善。此处介绍的框架可用于预测生态结果的性质和可能性，并在广泛的人为行为转变中优先管理，同时还提出了将人类，动物行为和生态联系起来的未来研究的重点。或相反，对行为影响确实会推动生态系统变化的情况进行错误的管理。此处介绍的框架可用于预测生态结果的性质和可能性，并在广泛的人为行为转变中优先管理，同时还提出了将人类，动物行为和生态联系起来的未来研究的重点。或相反，对行为影响确实会推动生态系统变化的情况进行错误的管理。此处介绍的框架可用于预测生态结果的性质和可能性，并在广泛的人为行为转变中优先管理，同时还提出了将人类，动物行为和生态联系起来的未来研究的重点。
