图1 传粉昆虫下降背景下授粉生态弹性不同机制示意图。以土地类型变化为代表的全球变化引起传粉昆虫群落结构变化。在①功能冗余、②密度补偿、③响应多样性、④连接周转; ⑤跨尺度弹性机制作用下, 传粉功能团保障传粉功能(如植物柱头上沉降花粉数量)在可接受的水平, 形成授粉生态弹性。

Fig. 1 The framework showing the different mechanisms of ecological resilience of pollination in the face of pollinator decline. The global changes, such as land use change, invoke the variations in pollinator community. Under the mechanisms of ①functional redundancy, ②density compensation, ③response diversity, ④interaction turnover; ⑤cross-scale resilience, pollinator communities are able to deliver an acceptable level of pollination functioning (e.g. pollen grains on stigma surface), forming the ecological resilience of pollination.
