The Institute for Biodiversity and Ecosystem Dynamics is one of eight research institutes of the Faculty of Science at the University of Amsterdam. The institute covers a wide range of subjects in both fundamental and applied research. Our scientific studies aim at a better understanding of the dynamics of ecosystems at all relevant levels, from genes to climate change, using a truly multi-disciplinary approach.
Supported by a NWO – ALW open programme grant, we have a vacancy for a PhD student on a project entitled: “Understanding sexual selection: which sex leads the dance when both are signallers?”
The most conspicuous form of sexual selection is Fisherian runaway selection, which occurs when one sex produces a pronounced sexual signal that is used by the other sex to choose a mating partner. However, when closely related species have very similar mating signals, these signals are important for species recognition to minimize the risk of interspecific attraction, in which case mating signals are likely to be under stabilizing selection. In both cases the underlying assumption is that one sex is the signaller and the other sex the responder. The forces of sexual selection are likely more complex when both sexes are signallers and responders. Such sexual communication occurs in one of the most diverse group of animals: moths. In moths, the species-specific female sex pheromones to which males are attracted from a distance have been studied in detail, because these pheromones can be used for pest management. However, at close-range males produce and emit a biosynthetically related but different pheromone, which is likely important for close-range female choice and/or male competition.
This project aims to determine the role of close-range courtship in generating variation in the sexual communication channel to assess the strength of mutual mate choice in a species where we have found a within-population polymorphism in the female sex pheromone. Understanding the forces of sexual selection in the speciation process is imperative for understanding biodiversity patterns in general and for pest management in particular.
This project will combine behavioral and chemical analyses with genetic (quantitative trait locus) analyses to answer the questions whether the female and male sex pheromone genetically linked, what are the genes underlying the male pheromone variation, what is the importance of male sex pheromone variation in female choice and what is its role in male-male competition.
- MSc in Biology, with focus on evolution, and interest in chemical ecology and entomology;
- experience with molecular biological techniques, preferably also with genetic analyses;
- interest to combine laboratory and field studies with genetic and chemical analyses;
- skills in experimental design and statistical analysis;
- proficiency in scientific writing and communication;
- ability to work in an international research team.
- Dr. Astrid T. Groot (project leader, supervisor)
