Climate mediates roles of pollinator species in plant–pollinator networks

Abstract Aim Understanding how climate conditions influence plant–pollinator interactions at the global scale is crucial to understand pollinator communities and ecosystem function respond environmental change. Here, we investigate whether drives differences in network roles of main insect orders: Diptera, Coleoptera, Lepidoptera Hymenoptera. Location Global. Time period 1968–2020. Major taxa studied Methods We collated networks from 26 countries territories across five Köppen–Geiger zones. In total, compiled data 101 that included >1500 plant species 167 families >2800 163 families. assessed composition among zones using a permutational ANOVA. calculated standard metrics for taxonomic groups used Bayesian generalized mixed models test zone influenced proportion links level generalism. Results found strong driver compositional dissimilarities between interactions. Relative other taxa, bees flies made up greatest When size was accounted for, were most generalist group tropics, whereas non‐bee Hymenoptera arid zones, syrphid polar networks. Main conclusions provide empirical evidence strongly influences different within Importantly, particularly flies, play central despite often being overlooked pollination research conservation. Our results identify need greater understanding change affects
