Significant results of the phylogenetic linear models (phylolm) testing for the effects of pollination vectors and climatic variables on the richness of total VOCs, fatty acid derivatives (FADs), amino acid derivatives (AADs), benzenoids, terpenoids, monoterpenes, sesquiterpenes, nitrogen-containing compounds (NCCs), and sulphur-containing compounds (SCCs) (N = 142).
