In the current global biodiversity crisis, the development of tools to define, quantify, compare, and predict resilience is essential for understanding the responses of species to global change. However, disparate interpretations of resilience have hampered the development of a common currency to quantify and compare resilience across natural systems. Most resilience frameworks focus on upper levels of biological organization, especially ecosystems or communities, which complicates measurements of resilience using empirical data. Surprisingly, there is no quantifiable definition of resilience at the demographic level. We introduce a framework of demographic resilience that draws on existing concepts from community and population ecology, as well as an accompanying set of metrics that are comparable across species.

在当前的全球生物多样性危机中，定义，量化，比较和预测复原力的工具的开发对于理解物种对全球变化的响应至关重要。但是，对弹性的不同解释阻碍了通用货币的发展，以量化和比较整个自然系统的弹性。大多数弹性框架都集中在生物组织的高层，尤其是生态系统或社区，这使使用经验数据进行的弹性测量变得复杂。令人惊讶的是，在人口统计水平上没有可量化的弹性定义。我们引入了人口弹性框架，该框架利用了来自社区和种群生态学的现有概念，以及一系列在物种间可比的指标。
