      Tolerance, defined as increased proximity, is an important commodity in primate societies, especially when resources are monopolizable. We examined the impact situational stressors have on the grooming for tolerance trade in a group of provisioned Tibetan macaques (Macaca thibetana) subject to tourism. Our results provide evidence for increased rates of self- directed behaviors (Bonferroni corrected ANOVA, N=12, p=0.042) and aggression (Bonferroni corrected ANOVA, N=12, p=0.012) during tourist presence and provisioning, making tolerance a commodity. We therefore predicted a higher proportion of interchange trading would occur when tourists and corn provisioning were present. Rates of post grooming proximity for 120 grooming bouts were compared to matched controls when grooming was absent. Post grooming rates were significantly higher than matched controls, supporting the existence of a tolerance market (T test, T(46)=4.524; p<0.001). We then compared the proportion of interchange behavior by condition (just corn, just tourists, both, neither) and found that a higher proportion of interchange occurred when neither stressor was present compared to when both stressors were present (Bonferroni corrected ANOVA, N=30, p= 0.045). These results suggest tourism and provisioning do not have the predicted impact on the tolerance trade, and may represent an acute stressor. Future research should examine proportion of interchange behavior during the summer, when tourism is high, compared to the winter, when tourism is low, to examine a seasonal effect.
