Taxon richness and species composition of the two groups of experimentally assembled nectar yeast communities considered in this study. The bee-only and bee + nectar experimental groups refer, respectively, to assemblages obtained by rubbing the glossae of bumble-bees on culture media and from probing H. foetidus virgin nectar with the bees’ glossae, incubating for 48 h and then streaking the inoculated nectar on culture media.
