moreo Michael Kessler for being an extraordinary supervisor. Thanks for your trust and guidance during all these years. I extend my gratefulness to Elke, Sarah and Sophie for welcoming me in your home. To the whole family for letting me have the piano these years, it brought magic to my life in Zurich. All members of POPCORN project for making this wonderful project happen. Professors Peter Linder and Florian Schiestl for your pertinent and relevant advice during my PhD committee meetings which helped me to keep on track with my timeline. Corinne Burlet for her excellent administrative support and for your invaluable help with the group's finances. Martin Spinnler for being honestly the best librarian I have ever met, thanks for keeping such an excellent library. Anna Glanzmann for giving me the opportunity to co-supervise her Master thesis, it was a pleasure and a wonderful learning experience for me too. Thanks for your wonderful company and help during fieldwork in Costa Rica.
