Spatiotemporal variation in the pollination systems of a supergeneralist plant: isAngelica sylvestris(Apiaceae) locally adapted to its most effective pollinators?

In terms of pollination systems, umbellifers (plants of the carrot family, Apiaceae) are regarded as generalists, since their (usually dichogamous) flowers are visited by a wide range of insects representing several taxonomic orders. However, recent analyses of insect effectiveness revealed that these plants may be pollinated effectively by a narrow assemblage of insect visitors. Of particular interest was whether populations of an umbellifer...
