生物多样性的加速丧失强调了了解物种如何实现复原力的必要性，即抵抗和从生物干扰中恢复的能力。然而，由于对物种恢复力的定义存在分歧和缺乏大规模分析，决定物种恢复力的因素仍然知之甚少。在这里，我们研究了910个动物和植物自然种群的生活史如何预测它们的内在弹性能力。我们表明，人口弹性可以通过补偿、抵抗和干扰后恢复的不同组合来实现。我们证明，这些弹性成分与物种的生活节奏和生殖策略相关的生活史特征高度相关。代代时间长的物种在干扰后需要更长的恢复时间，而繁殖能力强的物种具有更强的抗性和补偿能力。我们的发现强调了生命史特征在理解物种恢复力方面的关键作用，提高了我们预测自然种群如何应对干扰制度的能力。
Accelerating rates of biodiversity loss underscore the need to understand how species achieve resilience—the ability to resist and recover from a/biotic disturbances. Yet, the factors determining the resilience of species remain poorly understood, due to disagreements on its definition and the lack of large‐scale analyses. Here, we investigate how the life history of 910 natural populations of animals and plants predicts their intrinsic ability to be resilient. We show that demographic resilience can be achieved through different combinations of compensation, resistance and recovery after a disturbance. We demonstrate that these resilience components are highly correlated with life history traits related to the species’ pace of life and reproductive strategy. Species with longer generation times require longer recovery times post‐disturbance, whilst those with greater reproductive capacity have greater resistance and compensation. Our findings highlight the key role of life history traits to understand species resilience, improving our ability to predict how natural populations cope with disturbance regimes.
