ELECTRONIC SUPPLEMENTARY MATERIAL (ESM)List of ESM available for this article: Appendix A- Map of the Galápagos archipelago including location of field sites. Appendix B- Representation of the overall, quantitative, seed dispersal network. Appendix C- Quantitative interaction matrix. Appendix D- Fleshy fruit availability per site. Appendix E- Network level descriptors. Appendix F- Monthly fleshy fruit availability. Appendix G- Species level descriptors. Appendix H- Bird abundance estimates per site. Appendix I- Chi-square contingency table for the preferences between dry and fleshy fruits. Appendix J- Diagram of the integration of fruits by the two main dispersal routes at one site. APPENDIX AMap with the global position of the Galápagos archipelago (top right) and the locations of the field sites on the islands of Santa Cruz and San Cristóbal. 
APPENDIX BQuantitative seed dispersal networks for the eight sites in the Galápagos, visualized using the R package Bipartite 1.16 (Dormann et al. 2008). Paired native (left) and invaded (right) sites were studied in the dry and humid zones of the two most invaded islands. In each network, plants (bottom level) are dispersed by seed dispersers (top level); the width of the box for each plant, disperser and their interactions is proportional to the number of droppings containing intact seeds for that plant-animal pair. Alien plant species and their interactions are marked in black.
