  abstract = {{L}and-use changes through urbanization and biological invasions both threaten plant pollinator networks. {U}rban areas host modified bee communities and are characterized by high proportions of exotic plants. {E}xotic species, either animals or plants, may compete with native species and disrupt plant–pollinator interactions. {T}hese threats are heightened in insular systems of the {S}outhwest {P}acific, where the bee fauna is generally poor and ecological networks are simplified. {H}owever, the impacts of these factors have seldom been studied in tropical contexts. {T}o explore those questions, we installed experimental exotic plant communities in urban and natural contexts in {N}ew {C}aledonia, a plant diversity hotspot. {F}or four weeks, we observed plant–pollinator interactions between local pollinators and our experimental exotic plant communities. {W}e found a significantly higher foraging activity of exotic wild bees within the city, together with a strong plant–pollinator association between two exotic species. {H}owever, contrary to our expectations, the landscape context (urban vs. natural) had no eect on the activity of native bees. {T}hese results raise issues concerning how species introduced in plant–pollinator networks will impact the reproductive success of both native and exotic plants. {F}urthermore, the urban system could act as a springboard for alien species to disperse in natural systems and even invade them, leading to conservation concerns.},
