Scientific interest

In nature, plants are subject to selection exerted by both herbivores and pollinators simultaneously. However, despite of this fact there is little evidence on how herbivores can mediate the evolution of floral traits (either direct or indirectly), and in turn, its effects on the attractiveness to pollinators and plant fitness. In my project, pollinator- and herbivore-mediated selection and adaptation will be investigated to figure out what is the selective impact of pollinators and herbivores on floral traits and mating system. To achieve this, I will use an experimental evolution approach to track the changes in floral traits (essentially volatile organic compounds VOC) mediated by pollinators and herbivores across several plant generations of Brassica rapa, our study system. Experiments will be done in the field, with plants subjected to two different selection regimes: one with only pollinators, and the other with pollinators and herbivores. The same protocol will be done with rapid cycle Brassica rapa in greenhouse conditions.
