biostudies-literatureUnknown15(12)Fell AFrugivory interactions are key plant-animal mutualisms that facilitate seed dispersal and promote ecosystem resilience. However, these interaction networks are increasingly altered by the widespread introduction of non-native plants through human activities. The integration of such species into frugivory networks-and their consequences for network stability-remains poorly understood. Here, we examined the role of non-native plants in shaping frugivory network structure and <i>robustness</i> in a human-modified tropical landscape. Using DNA metabarcoding of faecal samples from 21 frugivorous bird species in Gamboa, Panama, we identified consumed plant species and quantified the contribution of non-natives to avian diets. Non-native plants significantly altered network structure, reducing <iEcology and evolutione72620https://www.ebi.ac.uk/biostudies/studies/S-EPMC12686967biostudies-literatureNon-Native Plants Alter Bird-Plant Frugivory Network Structure in a Human-Modified Tropical Landscape.PMC12686967Skeffington AFell ASaltonstall KBello CDuthie ABDent DHVargas MfalseNon-Native Plants Alter Bird-Plant Frugivory Network Structure in a Human-Modified Tropical Landscape.Frugivory interactions are key plant-animal mutualisms that facilitate seed dispersal and promote ecosystem resilience.
