在许多社会物种中，群体之间的竞争是直接影响群体层面的运动模式和空间使用并最终塑造群体生活和复杂社会性演变的主要因素。在这里，我们评估了影响野生狒狒（Papio cynocephalus）五个社会群体的群体统治地位的因素，特别关注统治地位的空间决定因素和失败的后果。当同种狒狒群体之间发生直接冲突时，获胜群体是通过每组中成年雄性的数量差异和/或在过去 9 或 12 个月内比对手更频繁地使用遭遇地点周围区域的群体来预测的。较短时间尺度（3 个月和 6 个月）内空间使用的相对强度不能很好地预测互动结果。失败的团体（而非获胜的团体）经历了明显的短期成本。失败的群体在竞争性遭遇后较少使用交互周围的区域（相对于他们在交互之前使用该区域的强度）。这些发现让我们深入了解群体间竞争对群体层面的空间使用模式的影响和后果。 (C) 2012 年动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
In many social species, competition between groups is a major factor proximately affecting group-level movement patterns and space use and ultimately shaping the evolution of group living and complex sociality. Here we evaluated the factors influencing group-level dominance among five social groups of wild baboons (Papio cynocephalus), in particular focusing on the spatial determinants of dominance and the consequences of defeat. When direct conflict occurred between conspecific baboon groups, the winning group was predicted by differences in the number of adult males in each group and/or groups that had used the areas surrounding the encounter location more intensively than their opponent in the preceding 9 or 12 months. Relative intensity of space use over shorter timescales (3 and 6 months) was a poor predictor of the interaction's outcome. Losing groups, but not winning groups, experienced clear short-term costs. Losing groups used the area surrounding the interaction less following an agonistic encounter (relative to their intensity of use of the area prior to the interaction). These findings offer insight into the influences and consequences of intergroup competition on group-level patterns of space use. (C) 2012 The Association for the Study of Animal Behaviour.
