Specialization of some plants on seed-eating pollinators is intriguing, especially when co-pollinators exclusively feeding on nectar are also present. We examined the stability of the morphological specialization of Trollius europaeus (L.) globeflowers with respect to Chiastocheta (Pokorny) flies by artificially opening the flowers. In the montane and subalpine environments studied, other visitors contributed 2% and 28% of all the visits, respectively, and visited open flowers nearly eight… CONTINUE READING
