The reliability of regional ecological knowledge to build local interaction networks: a test using seed-dispersal networks across land-bridge islands

Abstract: Building ecological networks is the fundamental basis of depicting how species in communities interact, but sampling complex interaction networks is extremely labour intensive. Recently, indirect ecological information has been applied to build interaction networks. Here we propose to extend the source of indirect ecological information, and applied regional ecological knowledge to build local interaction networks. Using a high-resolution dataset consisting of 22 locally observed networks with 17 572 seed-disp… Show more

“…We sampled plant-frugivore interactions on 22 islands from June 2019 to January 2022, covering three complete fruiting seasons (June to January). Island selection aimed to achieve a wide range of spatial configurations in terms of island area (mean ± SD: 79.29 ± 272.89 ha) and isolation (distance to the mainland: 1523.87 ± 584.53 m; distance to the nearest islands: 45.07 ± 25.50 m) among islands in our island system (Zhu et al, 2021(Zhu et al, , 2023. We used arboreal camera trapping, a noninvasive and cost-effective method to collect plant-frugivore interactions with high resolution on large scales (Zhu et al, 2022).…”
