当动物物种在当地灭绝时，它们所发挥的基本功能就会丧失，而生态系统则受到功能多样性下降的严重威胁。存在将功能、多样性和生态系统稳定性联系起来的理论，但未能评估在具有持久种群的物种中发生的功能丧失。一个物种的整个功能角色或其中的一个关键组成部分，可能在种群大量减少（功能灭绝）、种群增加或对种群、群落、栖息地或气候变化的行为适应之后丧失。在这里，我们提供了一个框架来确定在持续性种群中可能发生“隐性”功能丧失的情况。隐功能丧失可能广泛存在，严重威胁着全球生态系统的稳定。
The essential functional roles performed by animal species are lost when they become locally extinct, and ecosystems are critically threatened by this decline in functional diversity. Theory that links function, diversity, and ecosystem stability exists but fails to assess function loss that occurs in species with persistent populations. The entire functional role of a species, or a critical component of it, can be lost following large population declines (functional extinction), following population increase, or after behavioural adaptations to changes in the population, community, habitat, or climate. Here, we provide a framework that identifies the scenarios under which ‘cryptic' function loss can occur in persistent populations. Cryptic function loss is potentially widespread and critically threatens ecosystem stability across the globe.
