This book contains the abstracts of the presentations presented at the 50th annual meeting of the International Society for Applied Ethology (ISAE), held in Edinburgh, UK. The enduring aim of the ISAE is to encourage and support basic and applied research into the behaviour of animals as related to their use by humans. Ever since a small group of veterinarians first met in Edinburgh to form the Society of Veterinary Ethology (SVE), inspirational ethologists and veterinarians have helped shape the field of Applied Ethology. Scientists such as Niko Tinbergen, Karl Von Frisch and Konrad Lorenz, joint awardees of the 1973 Nobel Prize in physiology and medicine, have played an important part in helping to develop this subject. The 2016 ISAE conference will bring together applied ethologists from all over the world to share new discoveries and to discuss ways forward, under the general conference theme of 'Past and Future: Standing on the Shoulders of Giants'.
