Dominance interactions and hierarchies are of long-standing interest in the field of animal behaviour. Currently, dominance hierarchies are viewed as complex social structures formed by repeated interactions between individuals. Most studies on this phenomenon come from single-species groups. However, animals are constantly surrounded by and interact with individuals of other species. Behaviour and social interactions of individuals can be shaped by the presence or behaviour of other species in their social ecosystem, which has important implications for social behaviour in groups. Given how ubiquitous mixed-species animal groups are, deeper study of the relationships between mixed-species group (MSG) structure and dominance will be key to understanding constraints on individual behaviour and decision making. Here we call for more research into dominance interactions among individuals in MSGs. Greater understanding of the dynamics of dominance relationships among individuals in MSGs, whose size and composition can change considerably over shorter and longer term time frames, will be crucial to understanding their structure and functioning. This article is part of the theme issue 'Mixed-species groups and aggregations: shaping ecological and behavioural patterns and processes'.
在动物行为学领域，优势互动和等级制度一直是人们关注的焦点。目前，等级制度被视为由个体之间的反复互动形成的复杂社会结构。关于这一现象的大多数研究都来自于单一物种群体。然而，动物总是被其他物种的个体包围并与之相互作用。个体的行为和社会互动可能会受到其社会生态系统中其他物种的存在或行为的影响，这对群体中的社会行为有重要影响。鉴于混合物种动物群体的普遍性，深入研究混合物种群体（MSG）结构与优势之间的关系将是理解个体行为和决策限制的关键。在这里，我们呼吁对 MSG 中个体之间的优势互动进行更多研究。在 MSG 中，个体之间的优势关系的动态变化更为重要，因为 MSG 的大小和组成在较短和较长的时间框架内会发生相当大的变化，这对于理解其结构和功能至关重要。本文是主题为“混合物种群体和聚集：塑造生态和行为模式和过程”的一部分。
