* Abundance is expressed as visits per flower h–1, and was compared between populations by one-way random ANOVA (Gómez et al., 2007).
† Sobs is the observed number of pollinator species per population (observed species richness), and was compared between populations by rarefaction (Gómez et al., 2007).
‡ Based in the relative abundance of each functional group (Gómez et al., unpubl. res.).
