  abstract = {{T}he biodiversity hotspot of {N}ew {C}aledonia hosts high levels of endemism (74% of flora) that is threatened increasingly by climate change, habitat reduction, and invasive species. {T}he fruit-eating red-vented bulbul ({P}ycnonotus cafer) is currently invading the main island of the archipelago, and its recent dispersal out of urbanized habitats raises questions about its potential to disperse noxious plant seeds along urban corridors and beyond. {I}ndeed, the red-vented bulbul is considered a vector of several introduced plant species in its alien range including {M}iconia calvescens, {L}antana camara, and {S}chinus terebinthifolius. {W}e conducted a quantitative assessment of the bulbul's fruits consumption by analyzing the gut contents of shot birds. {W}e estimated gut passage times for four species of fruit found in gut contents ({S}.terebinthifolius, {M}yrtastrum rufopunctatum, {P}assiflora suberosa, and {F}icus prolixa) and tested the effects of bird digestion on seed germination rates for two species. {F}inally, we monitored the movements of individual {VHF} radio-tagged red-vented bulbuls. {A}ll of the consumed fruit species we identified here have red fleshy diaspore, including fruit of the shrub {M}.rufopunctatum that occurred frequently (9.6%) in bulbul gut samples. {M}edian gut passage times were short (15-41min), corresponding to short-distance seed transportation (77-92m). {T}he effect of gut passage was positive for the germination of the invasive {S}.terebinthifolius and negative for the endemic {M}.rufopunctatum, suggesting a potential bias in the contribution to the dispersal toward alien species. {T}his study provides the first integrated assessment of mechanisms involved in the seed dispersal effectiveness of this high-concern invasive bird species that is expected to face similar plant communities in most of its alien range in tropical islands. {M}ore generally, our results enhance knowledge of synergies between non-native frugivores and plant species dispersal.},
