Extinctions and coextinctions seriously threaten global plant–pollinator assemblies, and thus a better understanding of the geographic variability in their robustness is urgently required. Although the geographic patterns of species extinction rates are frequently explored, it remains largely unknown how the subsequent coextinction risk of species varies across environments. We hypothesize that the geographic variation of network robustness to extinctions is mediated by modularity – the tendency of a network to be organized in modules of strongly interacting species – because modularity buffers perturbations and varies across environments.

授粉网络稳健性的地理变化是由模块化介导的

灭绝和共同灭绝严重威胁着全球植物 - 传粉媒介的集合，因此迫切需要更好地了解它们健壮性的地理变异性。尽管经常探索物种灭绝率的地理模式，但在很大程度上仍不清楚物种随后的共灭绝风险如何随环境变化。我们假设网络对灭绝的鲁棒性的地理变化是由模块化介导的——网络倾向于以强相互作用物种的模块组织——因为模块化缓冲了扰动并在不同环境中变化。
