Fig. 2.

Floral volatile diversity across sampled species. (A) Bar graph depicting compound prevalence. Compound prevalence refers to the number of sampled species that produced a given compound. Compounds are arranged along the x-axis in order of decreasing prevalence. Colours represent the chemical class of the compound, including unidentified compounds. Asterisks above the bars indicate floral volatiles that are known to attract and elicit collection behaviour in male euglossine bees. (B) Bar graph indicating the average relative abundance for each floral volatile. Lines laid on top of the bars indicate the maximum and minimum relative abundance values. Compounds along the x-axis are arranged in the same order as in (A). Colours correspond to the colours used in (A) Compound abbreviations are as follows: DMB, dimethoxybenzene; MMC, methyl methoxycinnamate; PAME, phenylacetic methyl ester; BAPEEE, benzonic acid p-ethoxy ethylester.
