Bee preferences for floral resources
There were six morphotypes identified in both the pollen pellet and
resource survey data (Table 2). These included Apiaceae,Asteraceae_Lophate, Asteraceae_Spines, Fabaceae_Tricolporate,Lotus corniculatus , and Trifolium pratense . In addition,Monarda fistulosa and Poaceae were present in both data sets, but
only once and were therefore not included in the analyses. Analyzing
preference over all morphotypes provided marginal significance for
bumble bees, but was not statistically significant for honey bees (Table
5). Analyses of individual pollen morphotypes revealed that bumble bees
preferred Fabaceae_Tricolporate, and avoided Apiaceae, while there were
no preferences detected for honey bees (Table 5; Fig. 4).
