Data from: Rainforest fragmentation decreases the robustness of plant-frugivore interaction networks
[Description of the data and file structure] Between 5 October and 3 December 2023, we carried out 252 hours of active bird–fruit interaction observations (05:30–09:30 AM) along fixed 300 m forest-edge transects in six old-growth rainforest fragments in northern Costa Rica. On three randomized days...

| Sumario: | [Description of the data and file structure] Between 5 October and 3 December 2023, we carried out 252 hours of active bird–fruit interaction observations (05:30–09:30 AM) along fixed 300 m forest-edge transects in six old-growth rainforest fragments in northern Costa Rica. On three randomized days per fragment, three observers recorded the following data fields for every interaction (TABLE_S5.csv): Fragment ID; Date; Round; TreeID; Time; Tree species; Bird species; Bird Individuals Interacting; Tree Surrounding; Fruit amount. The Metadata_TABLE_S5.xlsx data file includes the description of all the variables. To ensure consistency, all observations of bird-fruit interactions were conducted along a fixed 300 m transect at the forest edge of each fragment, based on accessibility and availability of fruit-bearing trees. Interaction frequency was defined as the number of individual birds pecking or swallowing a fruit. If a bird remained in the tree for an extended period and consumed multiple fruits, this was still counted as a single interaction. To be considered a new interaction by the same bird species, the individual had to leave the tree and return after at least one minute. In addition, for each observed fruit-bearing tree, the number of ripe fruits were estimated at the time of observation and additionally the tree surrounding (single standing = no other tree in 5 m radius; edge tree = embedded in stand of numerous trees) was classified. |
