Abstract

Two previously studied groups of stumptail macaques were restudied to investigate stabilities and instabilities within group structures. Frequency data for nonsocial and dyad behaviors were collected. While there was considerable group stability, several important changes occurred. The most noteworthy group changes were in grooming and playing. Individual changes centered upon females. The first and fourth ranking females of one group switched dominance positions. The roots of this reversal were minimally reflected by aggressive and submissive interactions, and more fully exposed by quiet association patterns such as grooming, huddling, and sitting together. Increased frequencies of huddling, touching, and approaching indicated that the lowest ranking female of each group moved closer to other group members. There was no hint of this change in agonistic interactions.
