Accelerating rates of environmental change and the continued loss of global biodiversity threaten functions and services delivered by ecosystems. Much ecosystem monitoring and management is focused on the provision of ecosystem functions and services under current environmental conditions, yet this could lead to inappropriate management guidance and undervaluation of the importance of biodiversity. The maintenance of ecosystem functions and services under substantial predicted future environmental change (i.e., their 'resilience') is crucial. Here we identify a range of mechanisms underpinning the resilience of ecosystem functions across three ecological scales. Although potentially less important in the short term, biodiversity, encompassing variation from within species to across landscapes, may be crucial for the longer-term resilience of ecosystem functions and the services that they underpin.
加速的环境变化速度和全球生物多样性的持续丧失威胁着生态系统提供的功能和服务。许多生态系统监测和管理都集中在当前环境条件下提供生态系统功能和服务，但这可能导致不合适的管理指导和低估生物多样性的重要性。在预测的未来环境发生重大变化的情况下（即“弹性”）维持生态系统功能和服务至关重要。在这里，我们确定了三个生态尺度下支撑生态系统功能弹性的一系列机制。尽管在短期内可能不太重要，但生物多样性，包括从物种内部到景观之间的变化，对于生态系统功能及其支持的服务的长期弹性可能至关重要。
