[Reconciliation in hamadryas baboons, Papio hamadryas: testing the relationships quality hypothesis].

Post-conflict interactions between former opponents were investigated in a troop of hamadryas baboons, Papio hamadryas. This species is known for it's multilevel structure with evidently expressed hierarchy between males and females. Due to this fact hamadryas baboons represent an ideal object for testing the "relationship quality" hypothesis. The analyses were done on 436 PC-MC pairs of animals, which represented different social classes (harem male-female pairs, harem females, relatives, females from different harems. Male-male pairs, and female-subadult pairs). Reconciliation was practiced in different social classes of individuals: harem male-female pairs, harem female-female pairs, kin-kin pairs, male-male pairs, female-subadult pairs. Significant differences in the rate of reconciliatory tendency for different categories of interacting animals were found. Interactions between former opponents were highly selective. These may be interpreted as an indicator of the influence of the relation quality on the probability of reconciliation in hamadryas baboons.
