为了了解黑猩猩和黑猩猩社会组织差异的潜在因素，我们测量了乌干达基巴莱国家公园的黑猩猩和扎伊尔洛马科森林的矮黑猩猩最近的距离和选择。我们假设一组个体的空间组织应该反映他们之间的潜在关系。研究发现，与黑猩猩相比，矮黑猩猩最近的距离更小。距离的分布和可变性表明，黑猩猩比黑猩猩有更有限的最近邻居距离范围，避免非常接近的情况。焦点动物对最近邻居的性别的选择在物种之间是不同的。例如，雄性黑猩猩很少有另一只雄性作为他们最近的邻居，而雄性黑猩猩经常这样做。同样，当观察到雄性矮黑猩猩在一起时倾向于分开，而雌性黑猩猩在一起时倾向于分开。这些观察结果是根据这些物种中社会互动的性质来考虑的。
In an effort to understand factors underlying differences in the social organization of Pan troglodytes and P. paniscus, we measured the nearest neighbor distances and choices for chimpanzees in Kibale National Park, Uganda, and for bonobos in Lomako Forest, Zaire. We assume that the spatial organization of a set of individuals should reflect the underlying relationships between them. Bonobos were found to have smaller nearest neighbor distances than chimpanzees. The distribution and variability of the distances suggested that chimpanzees have a more restricted range of nearest neighbor distances than bonobos, avoiding situations of very close proximity. Selection of the sex of the nearest neighbor by a focal animal differed between the species. For example, male bonobos rarely had another male as their nearest neighbor, while male chimpanzees frequently did. Similarly, male bonobos tended to move apart when observed together, while it was female chimpanzees who tended to move apart when together. These observations are considered with respect to the nature of the social interactions in these species.
