最近的证据表明，过去干扰的频率和强度可以调节当前干扰的恢复率。此外，全球环境变化和人类活动的增加往往造成其他同时发生和/或随后发生的干扰。这些额外的干扰会延长恢复时间，甚至导致基线偏移，从而抑制系统返回到“真正”稳定的平衡状态。对于被认为在扰动后只表现出部分恢复的系统，回归时间的度量可以用另一个变化分量来代替，例如从扰动中恢复的能力（即恢复的完整性）[2]，以替代弹性。这种表示不需要假设完全恢复，并且更适合于跟踪受频繁多重干扰影响的系统的长期弹性（参见[2]中的图2）。的双变量度量[1]，它为监测弹性变化提供了一种新的，易于理解的表示。然而，与其他已开发的弹性指标类似[2，6]，它不能作为银方法依赖。相反，这些指标应具体针对研究系统和影响它们的干扰。未来的工作应该解决如何将这些指标结合起来，当可用时，可以应用于设定可量化的管理和恢复目标，以实现“弹性管理”的概念[6]。
Recent evidence shows that the frequencies and intensities of past disturbances can mediate recovery rates from current disturbances [12]. Moreover, global environmental change and increased human activities often cause other co-occurring and/or subsequent disturbances. These additional disturbances can prolong recovery, and even cause baselines to be shifted, thereby inhibiting the system from returning to a ‘truly’stable equilibrium state. For systems considered to exhibit only partial recovery after disturbances, the measure of return time could be substituted by another component of change, such as the capacity to recover from disturbance (ie, completeness of recovery)[2], to alternatively represent resilience. This representation does not need to assume full recovery, and would be more suitable for tracking the long-term resilience of systems affected by frequent, multiple disturbances (see Figure 2 in [2]).We welcome Hodgson et al.’s bivariate measure [1], which provides a new, easily understandable representation for monitoring changes in resilience. However, similar to other developed indicators of resilience [2, 6], it cannot be relied on as a silver bullet approach. Rather, these indicators should be specifically tailored to the study systems and disturbances affecting them. Future efforts should address how a combination of these metrics, when available, can be applied to set quantifiable management and restoration targets to operationalize the concept of ‘resilience management’[6].
