Floral syndromes in <i>Aquilegia</i> (Ranunculaceae) are associated with nectar- but not pollen-collecting pollinators

Despite their ubiquity, we did not find cues for selection by any of the pollen-collecting pollinators. Nevertheless, selection for traits associated with pollen-collecting pollinators, such as openly accessible stamens and a contrasted yellow floral centre (almost always present in Aquilegia), cannot be ruled out. In conclusion, floral syndromes in Aquilegia are associated with nectar-collecting pollinators only, maybe because they are more efficient at pollinating, which remains to be tested in field experiments.
