使用历史数据集，我们量化了120年来全球变化破坏美国伊利诺伊州温带森林林下群落植物-传粉者相互作用的程度。我们发现相互作用网络结构和功能的退化和50%的蜜蜂物种的灭绝。网络的变化可以归因于在杂类草和蜜蜂物候期的变化，从而导致时间上的不匹配，非随机的物种灭绝，并在修改后的景观现存物种之间的空间共现损失。授粉服务的数量和质量随着时间的推移而下降。历史上的网络表现出对干扰的灵活性;然而，我们的数据表明，网络对未来变化的弹性较低。
Using historic data sets, we quantified the degree to which global change over 120 years disrupted plant-pollinator interactions in a temperate forest understory community in Illinois, USA. We found degradation of interaction network structure and function and extirpation of 50% of bee species. Network changes can be attributed to shifts in forb and bee phenologies resulting in temporal mismatches, nonrandom species extinctions, and loss of spatial co-occurrences between extant species in modified landscapes. Quantity and quality of pollination services have declined through time. The historic network showed flexibility in response to disturbance; however, our data suggest that networks will be less resilient to future changes.
