植物-传粉者网络的互利互动提供了无数的经济、生态和文化成分，没有这些成分，就会产生严重的环境和社会后果。植物传粉网络越来越容易受到人为土地利用和气候变化的干扰。野蜂是授粉的核心，记录野蜂和花宿主之间独特的区域相互作用除了可以检测时间网络变化之外，还可以为当地生态和生物多样性提供强有力的见解。这项研究描述了过去125年来北方新英格兰野生蜜蜂植物传粉者网络的变化，并揭示了随着时间的推移，外来蜜蜂和植物类群的显着增加。在这里，我们记录了野生蜜蜂物种的减少与受威胁和濒危植物物种的历史联系。这些数据为植物传粉者网络的脆弱性提供了罕见的见解。在历史网络中记录的本地类群之间的显着的专业相互作用已经丢失，最有可能是由于这些现在受到威胁和濒危的植物物种的当地灭绝。随后的监测和保护工作的重点是栖息地恢复下降的野生蜜蜂和植物类群是未来保护区域本地多样性的基础。
The mutualistic interactions of plant‐pollinator networks provide myriad economic, ecological, and cultural constituents without which there would be severe environmental and societal consequences. Plant‐pollinator networks are becoming increasingly vulnerable to disturbance through intensifying anthropogenic land use and climate change. Wild bees are central to pollination and documenting unique regional interactions between wild bees and floral hosts provides powerful insights into local ecology and biodiversity in addition to the potential to detect temporal network variation. This study characterises the changes in a northern New England wild bee plant‐pollinator network over the past 125 years and reveals a striking increase in exotic bee and plant taxa over time. Here we document that declining wild bee species have historic ties to threatened and endangered plant species. These data provide a rare insight into the fragile nature of plant‐pollinator networks. Notable specialist interactions between native taxa that were recorded in historical networks have been lost, most likely due to local extirpation of these now threatened and endangered plant species. Subsequent monitoring and conservation efforts focused on habitat restoration for declining wild bee and plant taxa are fundamental to the future preservation of regional native diversity.
