灵长类社会行为的系统发育模型认为，核心社会特征是固有的物种特征，这些特征在很大程度上取决于物种的系统发育历史，而不是对当前社会生态条件的适应。这些模型预测，物种之间的社会结构方面的差异比物种内部的差异更大，并且它们将显示出强烈的系统发育信号。我们在猕猴身上测试了这些预测，重点关注优势梯度，这是社会结构的一个相对较少研究但至关重要的方面。我们使用了来自 14 个社会群体的数据，这些群体代表了生活在各种条件下的 9 种猕猴。我们检查了九个系统发育树中的反攻击比例和两个最近开发的系统发育信号的优势梯度（层次陡度）测量方法，这些系统发育树使用（1）可用的遗传数据集和（2）贝叶斯马尔可夫链蒙特卡罗（MCMC）和最大似然算法构建。等级陡度和反攻击显示物种之间存在显着差异，但物种内差异不一致。陡度和反攻击都显示出系统发育信号的证据，其中一种陡度测量和反攻击的结果特别强。我们的研究结果表明，尽管生活条件存在差异，但社会结构某些核心方面的物种间变异是由物种的进化关系决定的。因此，它们为系统发育模型提供了广泛的支持。 (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。
Phylogenetic models of primate social behaviour posit that core social traits are inherent species characteristics that depend largely on phylogenetic histories of species rather than on adaptation to current socioecological conditions. These models predict that aspects of social structure will vary more between species than within species and that they will display strong phylogenetic signals. We tested these predictions in macaques focusing on dominance gradients, a relatively little studied, yet central, aspect of social structure. We used data from 14 social groups representing nine macaque species living in a variety of conditions. We examined proportions of counteraggression and two recently developed measures of dominance gradients (hierarchical steepness) for phylogenetic signals in nine phylogenetic trees constructed using (1) available genetic data sets and (2) Bayesian Markov Chain Monte Carlo (MCMC) and maximum likelihood algorithms. Hierarchical steepness and counteraggression showed significant variation between species but inconsistent variation within species. Both steepness and counteraggression showed evidence of phylogenetic signals, with results being particularly strong for one steepness measure and for counteraggression. Our results suggest that between-species variation in some core aspects of social structure are shaped by species' evolutionary relationships, despite differences in living conditions. As such, they provide broad support for the phylogenetic model. (C) 2012 The Association for the Study of Animal Behaviour. Published by Elsevier Ltd. All rights reserved.
