✦ Synopsis
This paper reports a method for comparing the environments of nonhuman primates based on biophysical, thermal criteria. The method is applied to a n analysis of behaviors exhibited by group-living stumptail macaques (Macuca arctoides), documented by a group-scan observation technique, to test the hypothesis that the expression of social behavior is dependent on thermal conditions. Thermal conditions are identified by considering sky cover and the relative cooling power of the environment. The results show that the rates of occurrence of affiliative, play, and solitary behaviors are altered significantly at a relative cooling power at or above 550 kcal/m2/hr under cloudy conditions and at or above 600 kcallm2/hr under sunny conditions. In addition,
