Significant results of the phylogenetic linear models (phylolm) testing for the effects of pollination vectors and climatic variables on the emission rates 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 = 43).

	Estimate	P
Sesquiterpenes vs. Mean annual temperature	3.804	0.006
Sesquiterpenes vs. Maximum temperature of warmest month	-1.621	0.012
Sesquiterpenes vs. Minimum temperature of coldest month	-3.038	0.002
Sesquiterpenes vs. Precipitation of wettest month	3.368	0.006
NCCs vs. Maximum temperature of warmest month	1.622	0.027
NCCs vs. Mean annual precipitation	-0.289	0.024
NCCs vs. Gaussen index	0.306	0.022

The function phylolm fits phylogenetic linear models that allow the exclusion of the effect of phylogenetic distance. The standardized coefficients and P values are provided for each variable.
