Research project

Plants that rely on cross-pollination for reproduction offer various resources like nectar and pollen to reward flower visitors that transfer their pollen. Not all visitors that benefit from these rewards are true pollinators (mutualists), instead floral resources are often exploited without any pollination service (by antagonists). Exploitation ranges from nectar theft to total destruction of floral tissues (florivory). Mechanical, optical and chemical traits evolved in order to facilitate beneficial visits, but also prevent harmful visits. These traits may function as floral filters, such as floral scent that repels or attracts flower visitors.

Plant antagonists feeding on above and below ground plant tissues (herbivory) have been shown to induce resistance, resulting in direct responses like the production of defensive secondary metabolites or indirect responses like the release of volatiles that attract natural enemies of the attacking herbivores.

My research focuses on whether herbivory, florivory or floral exploitation induce flower specific defence responses and how this affects floral traits, and thus the behaviour of flower visitors and further the reproductive success of the plants. This will be done with special emphases on the effects on and of floral scents.
