Cortisol responses under different housing conditions in female squirrel monkeys (1982)

Gonzalez, C. A., Coe, C. L., Levine, S.

Abstract

Plasma levels of cortisol were significantly lower in pair-housed females than in those living in a social group or individually. The increment in cortisol levels after stress (handling and ether anesthesia) also was smaller in females housed in pairs. Dominant and subordinate partners of female pairs did not differ in their plasma cortisol levels.
