项目摘要

1. Coalition and alliance tactics of adult male chimpanzees were studied. (1) The oldest and adult male of M Group died around March 1993, but his death did not have any influence on the existing male dominance relationships. (2) No change in rank was seen among the 3 highest ranking and 3 lowest ranking males. The relationships among 3 middle-ranking males, however, were unstable and difficult to define. (3) The rivalry between the alpha and beta males was a major factor responsible for the group instability in 1993-94. However, the status of the alpha male was maintained, being supported by the coalition with the gamma male : Social grooming and solicitation of aid in combat were often seen between the alpha and gamma males. On the contrary, these coalitionary moves were rarely seen between the beta and gamma. Moreover, the temporary coalition between the beta and gamma was immediately cancelled when the alpha reconciled with the gamma. (4) The gamma male was occasionally challenged … More for status by a young adult male, who was, however, discouraged to continue to do so by the alpha male who intervened in the dispute by attacking the latter one-sidedly. Thus, the coalition between the alpha and gamma was mutually beneficial, being characterized as a reciprocal altruism.2. Nineteen chimpanzees of M Group died during this study period, 50% of which were killed by influenza. 3. Orphans of 2 to 4 years of age who lost their mothers by influenza were adopted and provided care by an adult female and several adolescent females and males. Thus, most of the orphans including the youngest survived their mothers' death. 4. Gestures, calls, and displays of chimpanzees were audio-visually recorded, which will be analyzed for detailed analysis of social relationships. Samples of blood, bone, muscle, and skeletons of several chimpanzees were obtained, which will be used for DNA typing. A lot of fecal and plant samples were also collected for either parasitological or chemical analyses. Less

1.研究了成年雄性黑猩猩的联盟和联盟策略。(1)M组最年长的成年雄性在1993年3月左右去世，但他的去世对现有的雄性优势关系没有任何影响。(2)在3只最高等级和3只最低等级雄性动物中未观察到等级变化。然而，3名中级男性之间的关系不稳定，难以界定。(3)阿尔法男性和贝塔男性之间的竞争是导致1993-94年群体不稳定的一个主要因素。然而，阿尔法男性的地位得到了与伽马男性联盟的支持：在战斗中经常可以看到阿尔法男性和伽马男性之间的社会梳理和请求援助。相反，这种联合行动在贝塔和伽马之间很少见。此外，当阿尔法与伽马和解时，贝塔和伽马之间的临时联盟立即被取消。(4)这只雄性伽马偶尔会受到挑战 ...更多信息一名年轻的成年男子为争取地位而进行了一场辩论，然而，这名男子被一名男子劝阻继续这样做，该男子单方面攻击后者，干预了这场争端。因此，阿尔法和伽马之间的联盟是互利的，被描述为互惠利他主义。M组的19只黑猩猩在研究期间死亡，其中50%死于流感。3.因流感而失去母亲的2至4岁孤儿被一名成年女性和几名青少年女性和男性收养和照顾。因此，大多数孤儿，包括最小的孤儿，在母亲去世后幸存下来。4.黑猩猩的手势、叫声和表现都被视听记录下来，这些都将被分析，用于社会关系的详细分析。获得了几只黑猩猩的血液、骨骼、肌肉和骨骼样本，这些样本将用于DNA分型。还收集了大量粪便和植物样本进行寄生虫学或化学分析。少
