Fig 5. Forage calendar highlighting variation in pollen collection among 6 apiaries in 2009.

Combined OTU counts for each of the 10 most common plant species-level assignments, based on the summed counts for all apiaries in 2009, are represented. Vertical axis represents the log₁₀ transformed counts per million mapped reads (cpm) for each taxon at each sampling point. Vertical bars are transparent to show data for multiple colonies sampled within the same apiary.
