Ecological study of stenophagous meat-eating in wild chimpanzees

黑猩猩的Mahale山脉，坦桑尼亚观察到猎物选择狩猎，猎物捕食者的关系，和社会方面的肉类共享。黑猩猩有强烈的捕食红疣猴的倾向，这一事实仍然是确定的。20世纪90年代黑猩猩狩猎频率的增加可能影响了疣猴的反捕食行为。对不同阿尔法男性多个时期的长期数据进行分析，得出的结果支持他们将肉类分享作为政治策略的假设。

Chimpanzees of the Mahale Mountains, Tanzania were observed with reference to prey selection in hunting, prey-predator relationships, and social aspects of meat-sharing. The fact remains firm that chimpanzees have a strong tendency to hunt red colobus. The increase of chimpanzee hunting frequency in 1990s may have affected anti-predator behavior in colobus. Analysis of long-term data covering multiple periods of different alpha males yielded the result supporting the hypothesis that they use meat-sharing as a political tactic.
