1. Herbivores target young leaves in forests worldwide. How this strong and predictable selection pressure has shaped plant defense syndromes remains unclear. Specifically, whether young leaf herbivory has led to general global patterns of shifting leaf defences during lead development (i.e. ontogenetic trajectories) remains unknown but likely. 2. Using meta-analysis, we have synthesized developmental shifts in chemical, physical, and indirect defence traits, as well as leaf nutrient content, during leaf expansion and maturation across 124 woody plant species. Leaf traits were compared for immature young leaves versus mature leaves within studies, and these developmental shifts were then compared across studies to characterize general patterns. 3. Traits shifted strongly during leaf maturation, giving rise to discrete defence syndromes, with young leaves having significantly greater nutrient and secondary chemistry concentrations but reduced toughness and indirect defence traits than mature leaves. These patterns corroborate a growing consensus on the importance of ontogeny in plant defences, illustrating ontogenetic trajectories at the scale of leaves. 4. Trait developmental shifts were stronger in species with synchronous than asynchronous leaf flushing, but whether this reflects variation across biomes remains unclear. 5. Future research on under-studied traits, such as alkaloids, cyanogenesis, leaf phosphorus content, and indirect defence traits, and in a more biogeographic context will provide additional insights into the generality of shifts in defence syndromes during leaf development.

The file lists all 527 studies of insect herbivore responses to the presence of endophytic fungi within plant tissues. Each study has the sample size plus the calculated values of Hedges' d from the analysis.

The data file "data tree level" includes the abundance of leaf miner species at the tree level, for both years and seasons within species and genetic diversity experiment. The data file "data plot level" includes the abundance of leaf miner species at the plot level, for both years and seasons within species and genetic diversity experiment. The abundance of miner species as well as miner species richness were obtained by using sample based rarefaction.
