Pollen transport networks reveal highly diverse and temporally stable plant-pollinator interactions in an Appalachian floral community

Floral visitation alone has been typically used to characterize plant-pollinator interaction networks even though it ignores differences in the quality of floral visits (e.g. transport of pollen) and thus may overestimate the number and functional importance of pollinating interactions. However, how network structural properties differ between floral visitation and pollen transport networks is not well understood. Furthermore, the strength and frequency of plant-pollinator interactions may vary across fine temporal scales (within a single season) further limiting our predictive understanding of the drivers and consequences of plant-pollinator network structure. Thus, evaluating the structure of pollen transport networks and how they change within a flowering season may help increase our predictive understanding of the ecological consequences of plant-pollinator network structure. Here we compare plant-pollinator network structure using floral visitation and pollen transport data and eva...

通常仅以 floral visitation（花访行为）来刻画植物-传粉者互作网络，尽管这种方法忽略了花访质量的差异（如花粉传递），因此可能高估传粉互作的数量及其功能重要性。然而，花访行为网络与花粉传递网络之间的结构特性差异尚未得到充分理解。此外，植物-传粉者互作的强度与频率可能在精细时间尺度（单季内）上存在变化，这进一步限制了我们对植物-传粉者网络结构驱动因素及其后果的预测性理解。因此，评估花粉传递网络的结构及其在花期内的变化，或有助于提升我们对植物-传粉者网络结构生态后果的预测性理解。在此，我们利用花访行为与花粉传递数据对比植物-传粉者网络结构，并评...
