优势的概念在动物界中无处不在,其中一些物种/群体的这种关系是严格的等级关系,而另一些则不是。近年来,利用计算能力的提高,出现了衡量优势的现代方法。其中一种技术,称为渗透和传导(Perc),使用有关优势关系流的直接和间接信息来生成等级排序,而不假设这些关系的线性。它还提供了一个新的度量标准,称为“优势确定性”,这是一个补充措施,以优势排名,评估在个人,二元和群体水平的等级关系的模糊程度。在这篇综述中,我们将(i)描述Perc如何在考虑数据的非线性层次结构和稀疏性的情况下测量优势秩--这里我们还提供了一个由Perc估计的优势确定性度量,它可以用来补充优势秩提供的信息;(二)总结我们的研究团队的一系列研究,反映了大型圈养恒河猴繁殖中"优势确定性"对个体和社会健康的重要性组;以及(iii)对支配等级研究的未来方向提出一些结论性意见和建议。这篇文章是主题问题的一部分“啄食秩序的百年:支配等级制度研究的现状和未来展望”。
The notion of dominance is ubiquitous across the animal kingdom, wherein some species/groups such relationships are strictly hierarchical and others are not. Modern approaches for measuring dominance have emerged in recent years taking advantage of increased computational power. One such technique, named Percolation and Conductance (Perc), uses both direct and indirect information about the flow of dominance relationships to generate hierarchical rank order that makes no assumptions about the linearity of these relationships. It also provides a new metric, known as ‘dominance certainty’, which is a complimentary measure to dominance rank that assesses the degree of ambiguity of rank relationships at the individual, dyadic and group levels. In this focused review, we will (i) describe how Perc measures dominance rank while accounting for both nonlinear hierarchical structure as well as sparsity in data—here we also provide a metric of dominance certainty estimated by Perc, which can be used to compliment the information dominance rank supplies; (ii) summarize a series of studies by our research team reflecting the importance of ‘dominance certainty’ on individual and societal health in large captive rhesus macaque breeding groups; and (iii) provide some concluding remarks and suggestions for future directions for dominance hierarchy research. This article is part of the theme issue ‘The centennial of the pecking order: current state and future prospects for the study of dominance hierarchies’.
