Spatial variation in pollinator-mediated selection (Delta beta(poll)) is a major driver of floral diversification, but we lack a quantitative understanding of its link to pollen limitation (PL) and net selection on floral traits. For 2-5 years, we quantified Delta beta(poll) on floral traits in two populations each of two orchid species differing in PL. In both species, spatiotemporal variation in Delta beta(poll) explained much of the variation in net selection. Selection was consistently stronger and the proportion that was pollinator-mediated was higher in the severely pollen-limited deceptive species than in the rewarding species. Within species, variation in PL could not explain variation in Delta beta(poll) for any trait, indicating that factors influencing the functional relationship between trait variation and pollination success govern a major part of the observed variation in Delta beta(poll). Separating the effects of variation in mean interaction intensity and in the functional significance of traits will be necessary to understand spatiotemporal variation in selection exerted by the biotic environment.
