Jan 10, 2022 · For example, social dynamics may be more likely to influence dominance hierarchies when orderly dominance hierarchies are beneficial . In group-living taxa, orderly, stable dominance relationships minimize aggression and improve efficiency [16,17,98], so self-organizing dominance hierarchies may be common. Large groups that lack orderly ...
Jan 12, 2022 · Dominance hierarchies were first described in chickens a century ago by a Norwegian zoologist who coined the term “pecking order.”. Since then researchers such as University of Cincinnati biologist Elizabeth Hobson have examined the intricacies of conflict and competition in species as diverse as primates, whales, birds and insects.

Jun 11, 2018 · Dominance Hierarchy. Dominance hierarchies characterize many species in which individuals live in close proximity to one another. The dominance hierarchy is a social structure within a group of animals in which certain individuals are dominant over others, and are therefore able to claim access to better resources in the form of food, mates, shelter, and other desirable commodities.
Hierarchies are maintained via social dynamics like punishment and threats [18,19] as well as signals that provide information about rank, including signals of individual identity and dominance [20,21]. In this review, we describe the behaviours used to estab-lish and maintain dominance hierarchies (figure 1).

Jun 29, 2023 · The authors show that social hierarchies have a pyramidal structure across species. From infancy, humans use this assumption to infer unobserved dominance relations.
Jan 10, 2022 · Dominance hierarchies are enigmatically both stable and dynamic. As a repeated pattern of asymmetry in agonistic outcomes between individuals, the concept of dominance is founded upon some element of stability . However, dominance relationships can also undergo rapid reversals, leading sometimes to dramatic changes in individual rank and group ...
Jan 1, 2022 · Dominance hierarchies were first cited by Thorleif Schjelderup-Ebbe in 1922, when he described the social organization of domestic chickens. The so-called pecking order describes the order in which individuals have access to food. This order was maintained by aggressive interactions, mainly pecking, in which the chicken that gives pecking to ...
