I would like to thank my supervisor Matthias Laska for the amount of energy and engagement that he has put into this work. I would also like to thank Mats Amundin as well as the carpenters and gibbon caretakers at Kolmården zoological park for all their help. Finally, I would like to thank Åsa Holm for her help in constructing the computer program that allowed me to optimize the day to day schedules that I used during the experiment.
