I am an evolutionary ecologist, widely interested in plant ecology and evolution, but my major focus is on plant-pollinator interactions and the ecology and evolution of flowers. I am particularly curious about understanding the patterns and processes of pollinator-mediated selection and how spatial and/or temporal variation in pollinator assemblages drives floral divergence and speciation in angiosperms. I am former interested in how other biotic factors or the abiotic environment impacts on plant-pollinator interactions and what are the consequences for floral adaptation. As an experimental field ecologist I like to study natural populations, but have also combined this with greenhouse experiments and will in upcoming projects expand to genetic approaches. I have worked with diverse study systems, but I am most fascinated by alpine flowering plants and orchids.
In my PhD I address different aspects of floral evolution and the role of pollinators in diversification in the plant family Orchidaceae. In a first part I will in a species-comparative approach investigate the correlation between the intensity of plants-pollinators interactions (quantified as degree of pollen limitation) and pollinator-mediated selection to reveal insights how biotic interactions shape selection regimes. In the second part, I will focus on understanding the evolution and adaptation of ecotype-divergence in the moth-pollinated orchid Platanthera bifolia. Here, I will combine field experiments and genetic tools to study the importance of floral trait differentiation for local pollinator adaptation, the patterns and mechanisms of pollinator-mediated selection and reproductive isolation, and distribution and patterns of genetic relationship.
