| Abstract: | The recommendations of a recent workshop (Leiden, Netherlands, November 17–18, 1990) concerning the use of animals in research on aggression and predation are listed. Major considerations included the grade of organisation/level of development of the organism, the duration and intensity of the interaction, post-treatment factors, the number of animals and reuse of animals. It is hoped that the recommendations will help scientists working in these areas to consider the increasingly important ethical dimension. |
