Fig. 2.

Relations between the (A) mean (±s.e.) attractiveness of Leopoldia comosa inflorescences and (B) mean (±s.e.) number of fertile flowers visited by attracted bees to fertile display size in the Mallorcan population. In (A), the results are presented separately for intact inflorescences and those from which the sterile flowers had been removed, and symbol size indicates the number of 5-min observation periods represented by an observation, ranging from 2 (smallest) to 22 (largest). In (B), the solid line illustrates the regression relation, the grey lines depict the indicated proportions of flowers visited, and symbol size indicates the number of bees contributing to a mean, ranging from 1 (smallest) to 8 (largest). Standard errors are asymmetric as data are ln-transformed.
