来自许多不同分类群的研究表明，优势度对个体空间利用有很大影响。尽管在雌性黑猩猩中占据主导地位的重要性过去一直存在争议，但现在越来越多的证据表明，排名非常重要。特别是，等级已被证明影响体重、觅食策略、联想模式，并最终影响繁殖成功。在这项研究中，我们研究了等级如何影响黑猩猩P.T.坦桑尼亚贡贝国家公园的SchweinFurthii。分析10年来的数据，我们发现，新移民使用的区域远离占主导地位的女性，而下属的网站保真度较低。我们还发现，地位较高的女性核心区较小，这种大小差异在食物稀缺时期明显存在，此时食物竞争最激烈。这些模式表明，占主导地位的女性胜过下属，迫使她们在其他地方定居，活动范围更广，并随着时间的推移转移空间使用。(C)2007年，动物行为研究协会。爱思唯尔有限公司出版。
Studies from many different taxa have demonstrated that dominance rank greatly influences individual space use. While the importance of dominance among female chimpanzees, Pan troglodytes, was debated in the past, mounting evidence now shows that rank is very important. In particular, rank has been shown to influence body mass, foraging strategies, association patterns, and ultimately, reproductive success. In this study, we investigated how rank influenced female space use among chimpanzees, P.t. schweinfurthii, at Gombe National Park, Tanzania. Analysing 10 years of data, we found that new immigrants used areas away from dominant females, and that subordinates had lower site fidelity. We also found that high-ranking females had smaller core areas and that this size difference was pronounced during periods of food scarcity when food competition is highest. These patterns suggest that dominant females outcompete subordinates, forcing them to settle elsewhere, range more widely, and shift their space use across time.
