P4G: Associational effects of herbivory across spatial scales (TreeDì_P4G Herbivory)

Local tree interactions might explain community-level associations of herbivores, their enemies, and tree diversity, but are likely modified by the wider tree neighborhood. The relative importance of potential bottom-up and top-down mechanisms underlying such associational effects, and their scale-dependence, remain unclear. Analyses of functional consumer traits, aided by molecular methods, may facilitate a mechanistic understanding Objectives: Herbivory & community structure of herbivore feeding guilds across space & time Top-down vs. bottom-up control Consequences for tree growth & productivity
