Compliance with ethical standards
:
: The experiments reported here comply with the <i>Guide for the Care and Use of Laboratory Animals</i> (8th edition, National Research Council, 2011) and also with the <i>American Society of Primatologists’ Principles for the Ethical Treatment of Primates</i>. A special ethical approval was not required because all experiments are considered as environmental enrichment for the animals and are thus covered by current Norwegian and Swedish Animal Welfare Laws for animals kept in zoos.
