Title: | Divergence in floral trait preferences between nonflower-specialized birds and insects on the Galápagos | Authors: | Hervías-Parejo, Sandra Heleno, Ruben Nogales, Manuel Olesen, Jens M. Traveset, Anna |
Keywords: | corolla size; entomophilous species; floral diversification; floral syndromes; flower shape; interaction frequency; nonmetric multidimensional scaling (NMDS); nonspecialized plant-visitor interactions; opportunistic birds; ornithophilous traits | Issue Date: | 2019 | Volume: | 106 | Issue: | 4 | Abstract: | The characteristic scarcity of insects on remote oceanic islands has driven nonflower-specialized vertebrates to broaden their trophic niches and explore floral resources. From our previous studies in the Galápagos, we know that native insectivorous and frugivorous birds visit a wide range of entomophilous flowers and can also act as effective pollinators. Here, we tested whether opportunistic Galápagos birds show any preference for specific floral traits, and if so, this preference differs from that of insects. | URI: | http://hdl.handle.net/10316/92065 | ISSN: | 0002-9122 1537-2197 |
