Species roles in plant–pollinator communities are conserved across native and alien ranges

Aim Alien species alter interaction networks by disrupting existing interactions, for example between plants and pollinators, and by engaging in new interactions. Predicting the effects of an incoming invader can be difficult, although recent work suggests species roles in interaction networks may be conserved across locations. We test whether species roles in plant–pollinator networks differ between their native and alien ranges and whether the...
