Figure A3.

Relative abundance (%) of the 20 most abundant OTUs (both fruit species considered together) in floral nectar from apple over three sampling days, including start of the flowering period (day 1, A), peak blooming (day 4, B), and three days later (day 7, C). Data are shown for every sample investigated in this study. OTUs were identified by a BLAST search against type materials in GenBank. Identification up to the species level is given when only 1 top hit was obtained. For identity percentages with GenBank entries, see Table 2. Sample ID: A: apple, D: day, O: orchard
