Tropical rainforests are species-rich, complex ecosystems. They are increasingly being negatively affected by anthropogenic activity, which is rapidly and unpredictably altering their structure and complexity. These changes in habitat state may expose tropical animals to novel and unpredictable conditions, potentially increasing their extinction risk. However, an animal's ability to cope with environmental change may be linked to its personality. While numerous studies have investigated environmental influences on animal personalities, few are focused on tropical species. In this review, we consider how behavioural syndromes in tropical species might facilitate coping under, and adapting to, increasing disturbance. Given the complexity of tropical rainforests, we first discuss how habitat complexity influences personality traits and physiological stress in general. We then explore the ecological and evolutionary implications of personality in the tropics in the context of behavioural flexibility, range expansion and speciation. Finally, we discuss the impact that anthropogenic environmental change may have on the ecological integrity of tropical rainforests, positing scenarios for species persistence. Maintaining tropical rainforest complexity is crucial for driving behavioural flexibility and personality type, both of which are likely to be key factors facilitating long term persistence in disturbed habitats.
热带雨林是物种丰富、复杂的生态系统。它们越来越受到人为活动的负面影响，人为活动正在迅速且不可预测地改变其结构和复杂性。栖息地状态的这些变化可能使热带动物面临新的、不可预测的状况，从而可能增加它们的灭绝风险。然而，动物应对环境变化的能力可能与其个性有关。虽然众多研究调查了环境对动物个性的影响，但很少有研究聚焦于热带物种。在这篇综述中，我们思考热带物种的行为综合征如何在日益增加的干扰下促进应对和适应。鉴于热带雨林的复杂性，我们首先讨论栖息地复杂性一般如何影响个性特征和生理应激。然后，我们在行为灵活性、分布范围扩张和物种形成的背景下探讨热带地区个性的生态和进化意义。最后，我们讨论人为环境变化可能对热带雨林生态完整性产生的影响，提出物种持续存在的情景。维持热带雨林的复杂性对于推动行为灵活性和个性类型至关重要，而这两者都可能是促进在受干扰栖息地长期持续存在的关键因素。
