Dataset and R codes for: Global convergence and fine-scale shifts in plant–bee network structure across the honeybee’s native and non-native ranges

Pollinator communities are increasingly influenced by human-mediated species introductions, yet the global impacts of invasive pollinators on network structure remain poorly understood. We performed a systematic review that compiled 80 quantitative plant–bee interaction networks encompassing the native and non-native ranges of the western honeybee (Apis mellifera) and analyzed network organization at three hierarchical levels: the overall network architecture (macro-scale), participation in motif classes (meso-scale), and species’ structural roles (micro-scale). Macro-scale metrics (including connectance, nestedness, modularity, and robustness) did not differ between ranges, indicating broad structural similarity across the species’ global distribution. However, finer-scale analyses revealed significant range-dependent shifts. In non-native regions, A. mellifera exhibited a lower within-module degree, suggesting reduced integration within network compartments, and participated more frequently in fan motifs but less in core–peripheral motifs, implying altered dominance and resource-use patterns. These findings show that A. mellifera maintains a largely conserved structural role worldwide, but that subtle shifts in local connectivity and sub-structural organization occur outside its native range. Overall, our results reveal that while invasive generalists can promote structural convergence in mutualistic networks at macro scales, cross-scale analyses uncover hidden variations that may influence the long-term stability and resilience of pollination systems under global change.
