碩士 === 國立中山大學 === 生物科學系研究所 === 96 === The purpose of this study was to investigate the post-conflict reconciliation, consolation, solicited affiliation, stress and redirection in the captive Formosan macaques（Macaca cyclopis）in the Taipei Zoo. I used the post-conflict and matched-control (PC-MC) method to calculate the conciliatory tendency (CCT) and the triadic contact tendency (TCT) in adult macaques. The mean CCT for kin (83.33%) was significantly higher than that for non-kin (0.36%), and victims initiated reconciliation toward aggressors in higher rank classes significant more than both of them were in the same rank. The mean TCTs of aggressors and the victims were similar toward different triadic contact opponents (opponent’s kin, own kin, unrelated individual). The ratio of the attracted pairs of victims who reconciled with aggressors by sociosexual behavior (15.23%) was significant higher than dispersed pairs (non-exist). In addition, the ratio of attracted pairs of victims who reconciled with unrelated third party by affiliation (46.72%) was significant higher than the dispersed pairs (21.76%). The similar situation also occurred in sociosexual behavior (28.68% verse 1.75%). However, aggressors and victims had similar chance to take the initiative affiliation after conflict (P > 0.05) The frequency of self-directed behavior (SDB) of Formosan macaques was slightly higher in the first 4 minutes in PC. The frequency of SDB after reconciliation (14.6 bouts/100 min) was not significantly lower than that before reconciliation (23.2 bouts/100 min) or when affiliation behavior did not occur (22.3 bouts/100 min). When the conflict opponents were kin, the SDB frequency (16.1 bouts/100 min) was not significantly lower than non-kin (24.1 bouts/100 min). The targets of redirect aggression were mostly unrelated individuals (82.61%). The mean CCT of the victims (16.50%) did not significant differ from the mean consolation TCT of the victims (48.81%), which indicated that reconciliation and consolation played similar critical roles after conflict. The sociosexual behavior performed by victims only occurred in PC (34.85%), which indicated the purpose of sociosexual behavior in reconciliation was to prevent further attack from aggressors. The chance of victims did not involve reconciliation and consolation, but solicited affiliation with a third party in PC was 23.32%. This indicated that the solicited affiliation might function to exchange the aggressive supports from the third party in the following conflicts.
