Table I. Percentages of pollen recorded for each taxon or group of taxa on each sampling day

Table II. Protein content for each pollen type expressed as mg protein/g pollen and μg protein/mL dissolution where 0.025 g pollen was dissolved in 2 mL Tris/EDTA buffer

Figure 2. The relationship between relative contribution by weight (% Weight; ▪) and protein percentage (% Prot; □) for each plant species harvested by honey bees over the study period. Information on the relative protein content of each species in mg/g pollen (◊) is given for each day tested.
