No effect of acute crowding on the behavior of hamadryas baboons (Papio hamadryas) (2001)

Abstract

Aggressive, submissive, affiliative and self-directed responses of the six adults - two males and four females - were recorded in their small indoor quarters versus large outdoor section of their enclosure. Agonistic behavior, and scratching, an indicator of anxiety in primates, did not increase during crowding. .. Perhaps male hamadryas baboons exert such a controlling influence that conflict management among the other group members is unnecessary during crowding.
