由于很难跟踪微生物的扩散，很难区分分散和物种分类对微生物群落组装的相对重要性。在这里，我们利用一个详细的多层次网络来检查花内细菌群落组装的驱动因素。我们在内华达山脉的一个共花群落中观察了20种重点植物的花卉访客，揭示了289种节肢动物。我们还分析了每种花上的细菌群落。我们发现，具有相似访客群落的植物物种往往具有相似的细菌群落，并且在构建花卉细菌群落时，访客身份比植物关联性更重要。然而，作为节肢动物访问中心的植物物种并不一定是花卉细菌的中心，这表明物种分类具有重要作用。在植物种类中，访花双翅目(苍蝇)、蜜蜂和非蜜蜂膜翅目的组成最能预测花上的细菌种类组成。综上所述，我们的分析表明，扩散在确定不同植物物种之间微生物群落的相似性方面很重要，但在确定花卉细菌网络的整体宏观结构(嵌套性、模块化)和微观结构(基于共享交互作用的连接性)方面不那么重要。因此，多层网络方法使我们能够解决当将网络视为独立实体时不能考虑的社区集合的特征。
Due to the difficulty of tracking microbial dispersal, it is rarely possible to disentangle the relative importance of dispersal and species sorting for microbial community assembly. Here, we leverage a detailed multilevel network to examine drivers of bacterial community assembly within flowers. We observed flower visitors to 20 focal plant species in a coflowering community in the Sierra Nevada, revealing 289 species of arthropods. We also analyzed bacterial communities on flowers of each species. We found that plant species with similar visitor communities tend to have similar bacterial communities, and visitor identity to be more important than plant relatedness in structuring floral bacterial communities. However, plant species that were hubs of arthropod visitation were not necessarily hubs of floral bacteria, suggesting an important role for species sorting. Across plant species, the composition of flower‐visiting Diptera (flies), bees and non‐bee Hymenoptera best predicted bacterial species composition on flowers. Taken together, our analyses suggest dispersal is important in determining similarity in microbial communities across plant species, but not as important in determining the overall macrostructure (nestedness, modularity) and microstructure (connectedness based on shared interactors) of the floral bacterial network. A multilevel network approach thus allows us to address features of community assembly that cannot be considered when viewing networks as separate entities.
