Evolutionary shifts between pollination systems are often accompanied by modifications of floral traits, including olfactory cues. The authors investigated the implications of a shift from passerine bird to beetle pollination in Protea for floral scent chem., and also explored the functional significance of Protea scent for pollinator attraction. Using headspace sampling and gas chromatog.-mass spectrometry, they found distinct differences in the emission rates and chem. composition of floral scents between eight bird- and four beetle-pollinated species. The amount of scent emitted from inflorescences of beetle-pollinated species was, on average, about 10-fold greater than that of bird-pollinated species. Floral scent of bird-pollinated species consists mainly of small amounts of green-leaf volatiles and benzenoid compounds, including benzaldehyde, anisole and benzyl alc. The floral scent of beetle-pollinated species is dominated by emissions of linalool, a wide variety of other monoterpenes and the benzenoid Me benzoate, which imparts a fruity odor to the human nose. The number of compounds recorded in the scent of beetle-pollinated species was, on average, greater than in bird-pollinated species (45 vs. 29 compounds, resp.). Choice experiments using a Y-maze showed that a primary pollinator of Protea species, the cetoniine beetle Atrichelaphinis tigrina, strongly preferred the scent of inflorescences of the beetle-pollinated Protea simplex over those of the bird-pollinated sympatric congener, Protea roupelliae. This study shows that a shift from passerine bird to insect pollination can be associated with marked up-regulation and compositional changes in floral scent emissions.
