Resilience is a key concept in ecology and describes the capacity of an ecosystem to maintain its state and recover from disturbances. Numerous metrics have been applied to quantify resilience over a range of ecosystems. However, the way resilience is quantified affects the degree to which different trajectories of ecosystem recovery from disturbance are represented as ‘resilient’, precluding a comparison of disturbance responses across ecosystems and their properties and functions. To approach a broadly comparable assessment of resilience we suggest using a bivariate framework that jointly considers the disturbance impact and the recovery rate, both normalized to the undisturbed state of a system. We demonstrate the potential of the framework for attribution and integration across the various components underlying resilience.

迈向可量化的复原力

复原力是生态学中的一个关键概念,它描述了生态系统维持其状态并从干扰中恢复的能力。许多指标已用于量化一系列生态系统的弹性。但是,复原力的量化方式会影响从干扰中恢复生态系统的不同轨迹表示为“弹性”的程度,从而无法比较整个生态系统中的干扰响应及其特性和功能。为了对弹性进行大致可比的评估,我们建议使用双变量框架,该框架共同考虑干扰影响和恢复率,均将其归一化为系统的未干扰状态。我们展示了弹性基础各个组成部分的归因和集成框架的潜力。
