I would like to thank the staff at Avesta Visentpark, Borås Djurpark, Skånes djurpark, Skansen, Lycksele Djurpark and Kolmården for allowing me to study their European bisons and for all their help during the visits. Additionally, I would also like to thank Eriksberg Vilt- och Naturpark  for enabling me to study their bisons although the data was not enough to be included in this study.

I also wish to thank my supervisor Mats Amundin for his help during the project.

Last but not least, Annika Hofling for all the help and assistance during the data collection as well for being a great travelling partner.
