Mantel test results (Mantel coefficient of correlation (r_M) and p-values) for chemical distance matrices based on proportions (prop.) and presence/absence (P/A) of compound groups correlated against phylogenetic and geographical distances in stingless bee species from Southeast Asia, Australia and Central America. Italic p-values are significant after FDR correction.
