The stress response of the organism depends on a variety of criteria and the same stressor can elicit totally different stress responses in distinct individuals. Every animal shows its individual stress response, possibly with clear changes in some parameters or virtually no changes in others. The prediction of such individual stress responses via methods which are both easy to assess and non-invasive would provide significant advantage for the experimental design in the field of stress research. The model of chronic psychosocial stress in Tupaia belangeri was elaborated in the recent years and is based on the pronounced territoriality of the animals. The aim of the present study was to test a variety of parameters as potential predictors for the individual stress responses. It could be shown that the age of the animals, basal body weight, baseline hormone levels and locomotor activity can serve as predictors for the extent of the stress response with respective to certain parameters. The present data provide valuable information for further studies on individual stress responses. On the basis of the present results it is now possible to select individual male Tupaia belangeri according to their baseline values in distinct physiological parameters. For example, if the focus is on the stress induced changes in body temperature it is advisable to select younger animals whereas alterations in the sleep rhythm can be better observed in older animals.
