Social groups are commonly structured as a dominance hierarchy based on a ranking system whereby higher-ranked individuals have better access to valuable resources such as food and mates but they also tend to assume greater responsibilities in providing leadership and maintaining order. 2,3 The formation of a hierarchical ranking system requires the dominant-subordinate relationship to be ...
Jun 10, 2020 · A recent paper in Cell Research by Wang et al. offers a nice inroad into the genetics and evolution of dominance behavior. 5 This study took a somewhat unusual approach. The authors began by ...

520 species. A dominance hierarchy (formerly and colloquially called a pecking order) is a type of social hierarchy that arises when members of animal social groups interact, creating a ranking system. A dominant higher-ranking individual is sometimes called alpha, and the submissive lower-ranking individual a beta.
Jan 10, 2022 · Signals of dominance provide information about dominance rank (e.g. dominant ant queens have cuticular hydrocarbons that provide information about rank and influence queen/worker interactions ). Signals of individual identity are unique phenotypes that receivers learn and associate with individual-specific information about the sender like dominance rank.
Feb 19, 2018 · One approach to bridge this gap between species is to establish links between fundamental computational principles of social dominance processes and the brain system level. In particular, the fact that learning social hierarchies may rely on similar principles as learning stimuli–reward associations by reinforcement has been underappreciated [4,5,19] .

Dominance Hierarchy. A dominance hierarchy refers to the ranking system that results from competitive interactions between individuals in group-living mammals. It influences their behavior, reproductive success, and overall health. However, it is important to note that dominance hierarchies based on agonistic behavior are just one aspect of ...

Apr 6, 2015 · The study of dominance relations in non-human animals began with the observation that groups of hens often form strictly linear dominance hierarchies—a particular form of hierarchy in which all pairs of individuals (dyads) have a dominant–subordinate relation, and all possible relations are transitive (i.e. if A is dominant to B and B is dominant to C, then A is dominant to C) [14,15].
