Fig 4. Forage calendar for two honey bee colonies (red and blue bars) located in Apiary 3 in 2009, highlighting the temporal progression of plant taxa.

Combined OTU counts for the 20 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.
