Foliar herbivory pushes plant individuals towards the periphery of a plant-floral visitor interaction network

Indirect interactions are major forces structuring communities. In terrestrial ecosystems, changes in plant traits caused by herbivory have the potential to mediate cascades of indirect interactions that can profoundly affect community structure. We have begun to understand the mechanisms behind indirect effects mediated by trait changes in plants, but we still know little about how these interaction-level mechanisms affect higher levels of community organization, in particular network structure, and how this is dependent on community context. In this study, we aimed to understand how herbivory affects floral traits, flower visitation and the position of plant individuals in a plant-flower visitor network. To do this, we assessed the natural incidence of leaf and flowerhead herbivory in a tropical shrub and tested how it affects flowerhead density and the interactions between flowers and Lepidoptera, Hymenoptera, and Diptera at the pairwise and network levels. We also tested how the loc..., , # Foliar herbivory pushes plant individuals towards the periphery of a plant-floral visitor interaction network

## Description of the data and file structure

In December 2015, we marked all *T. adenantha* individuals found along a 2.5 km trail at the Reserva Biológica Municipal da Serra do Japi, Jundiaí, São Paulo, Brazil (23°14'01.3\"S 46°56'09.2\"W), totaling 150 plants. Of these, 61 either died or did not flower during the study, leaving 89 individuals included in the analysis. Between December 2015 and May 2016, we randomly sampled plants with at least one reproductive branch (approximately five individuals per day, totaling 15 per month over 21 sampling days). Each plant served as an independent unit for data collection, which included:

- Observation of flowerhead visitation (1h observation of a single focal reproductive branch per plant)
- Flowerhead density (total flowerheads in anthesis per plant)
- Flowerhead her...,
