... of animal-pollinated plants is to transport pollen to flower-visiting pollinators. We adopted Hypochaeris radicata as a model species to investigate the functional morphology of the typical floral feature of Asteraceae, a pollen-bearing style. Using quantitative experiments and numerical simulations, here...

... and respond to floral humidity cues has been only established for hawkmoths when they locate and extract nectar while hovering in front of some moth-pollinated flowers. To test whether floral humidity can be used by other more widespread generalist pollinators, we designed artificial flowers that presented...

...Tianfei Peng; Francisca H. I. D. Segers; Fabio Nascimento; Christoph Grüter ABSTRACT Plants and pollinators form beneficial relationships, with plants offering resources in return for pollination services. Some plants, however, add compounds to nectar to manipulate pollinators. Caffeine...

...Ismael Gatica Hernández; Florencia Palottini; Ivana Macri; Claudio Rómulo Galmarini; Walter Marcelo Farina ABSTRACT The honey bee is the most frequently used species in pollination services for diverse crops. In onion crops ( Allium cepa ), however, bees avoid visiting certain varieties, being...

...Martin Streinzer; Hannes F. Paulus; Johannes Spaethe SUMMARY Orchids of the genus Ophrys are pollinated by males of solitary bees and wasps through sexual deception. The flowers mimic the behaviourally active compounds of the sex pheromone of receptive females and thus attract males that seek...

... pollinators such as the tobacco hornworm moth, Manduca sexta . We used arrays of artificial flowers to investigate the flower handling behavior (the ability to locate and drink from floral nectaries) of naïve moths, looking specifically at: (1) how the shape and size of flat (two-dimensional) artificial...
