Tree phytochemical diversity and herbivory are higher in the tropics

The datasets analyzed in the current study, including the output of the molecular network, sample-sample chemical structural and compositional similarity (entire metabolites and seven different biosynthetic pathways), plot-species-community data, and the phylogenetic tree of 206 tree species.The R material contains scripts to replicate the analyses from the manuscript, including calculating the chemical structural and compositional similarity (CSCS) index between samples, assessing the number of unique chemical compounds for each forest plot across three climatic zones, calculating chemical rarefaction and NMDS, quantifying the phylogenetic signal of PSM across species-level phylogeny, calculating the alpha, and beta (observed and null model) diversity at community-level, exploring the elevational pattern of herbivorous pressure.
