Jan 10, 2022 · 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 hierarchies or groups where rank instability is less costly may be less likely to have self-organizing dynamics.

Jan 10, 2022 · Such models frame dominance hierarchies as the product of evolved strategies for resolving disputes over limited resources and for minimizing repeated, escalated conflicts in group-living animals. In these models, the evolutionarily stable strategy 1 under many different conditions predicts that some players will yield resources to specific others, giving rise to a system of dominance rank.
when and why dominance hierarchies emerge from social interaction in group-living species. The evolutionarily stable behavioral strategies find their counterparts in a suite of psychological adaptations--a “dominance psychology”--that should be observable in both dominants and subordinates.

Apr 16, 2002 · Dominance hierarchies, known in the mathematical literature as tournaments, are social structures consisting of dominance relationships between all pairs of individuals in a group. In a linear hierarchy one individual dominates all the other individuals in a group, a second dominates all but the first, and so on down to the last individual who ...
Jan 1, 2021 · In small groups of animals, the dominance hierarchy may be linear (Craig 1986), which means that the highest ranking animal (A) is dominant over the second highest animal (B), who is dominant over C and so on down to the lowest ranking animal. A dominance hierarchy can also be triangular, where A is dominant over B and C, but C is dominant over A.

Jan 10, 2022 · Most recently, work in chickens, cichlids and mice tracking all interactions among small newly formed groups provides an in-depth look into how dominance hierarchies emerge and persist after formation, showing that even after establishment, shifting dominance relationships still tend to change from one transitive network to another . These results suggest that dominance hierarchies are best ...
