优势等级代表了自然界中一些最基本的社会结构，而攻击性是在许多动物物种中建立这种结构的关键。以往的研究主要集中在个体先前经验和生理特征在通过攻击性决定社会等级方面的相对影响。在这里，我们研究了亚社会小木蜂Ceratina calcarata形成优势等级的行为潜力。生理特征和社会经验都被发现在预测该物种未来的交互行为方面发挥了部分作用。我们的结果表明，个体的大小与初次接触中的优势有关，而先前的经验在预测随后的接触中的优势方面发挥了更大的作用。在社会进化的早期阶段，社会系统很可能遵循同样的预测因素，而这些因素是未来研究社会进化和主导等级的行为起源的关键目标。
Dominance hierarchies represent some of nature’s most rudimentary social structures, and aggression is key to their establishment in many animal species. Previous studies have focused on the relative influences of prior experience and physiological traits of individuals in determining social rank through aggression. Here we examine the behavioural potential for dominance hierarchy formation in the subsocial small carpenter bee, Ceratina calcarata . Both physiological traits and social experience were found to play partial roles in predicting future interactive behaviour in this species. Our results suggest that individual size is associated with dominance in initial encounters, while prior experience plays a larger role in predicting dominance in subsequent encounters. Social systems in the early stages of social evolution may well have followed these same predictive factors and these factors are key targets for future studies of social evolution and the behavioural origins of dominance hierarchies.
