Ecologists at Princeton University recently discovered top-ranking male baboons exhibit higher levels of stress hormones than second-ranking males, suggesting that being at the top of a social hierarchy may be more costly than previously thought. By studying baboon groups in Kenya, the researchers, for the first time, identified higher levels of stress hormones, or glucocoricoids, in alpha males as compared to beta males.
