Species introductions shift seed dispersal potential more than extinctions across 120 island plant–frugivore communities

These databases were created by the Frugivory on Islands Globally (FIG) consortium, a group of more than 30 (local) island experts, through over a decade of work. We would very much appreciate being involved in future work using this data (contact: [e-mail]). These databases, spanning 120 oceanic islands within 22 archipelagos worldwide, consist of insular frugivorous birds, mammals, and reptiles (native, extinct, and introduced; 3,050 occurrences of 613 unique species), fleshy-fruited plants (4,026 occurrences of 1,784 unique species), and their morphological and behavioural traits related to seed dispersal. For frugivores, traits include seed handling, habitat use, diet, gape size, body mass, animal class, percentage fruit in diet; for plants, seed length and width. R scripts are archived at Zenodo (https://doi.org/10.5281/zenodo.16986851), and accessible via GitHub (https://github.com/JHHeinen/120-Island-frugivore-communities/).
