Jan 10, 2022 · One explanation is that conventions are more likely to occur when the costs of competition over dominance rank outweigh the benefits of high dominance rank . For example, conventions are particularly common in taxa that live in long-term social groups with many relatives because there are both direct and indirect fitness costs to group conflict (e.g. primates, social insects) [ 75 , 78 ].

In most cases the dominance hierarchy is relatively stable from day to day. Direct conflict is rare; an animal usually steps aside when confronted by one of higher rank. Temporary shifts occur; for instance, a female baboon mated to a high-ranking male assumes a high rank for the duration of the pair bond. An individual weakened by injury ...

Dominance hierarchies. A dominance hierarchy is a ranking system in animal groups. Think of the term “alpha male”. Some animals are more dominant while others exhibit greater submissiveness. Although not widely studied, dominance hierarchies are associated with ethanol use in both rodents and primates.

Jan 1, 2021 · In a completely transitive dominance hierarchy, there are no circular dominance relationships, in which, for example, A is dominant to B, B is dominant to C, and C is dominant to A. Rather, the rank order is entirely linear; in a group of six individuals, the top-ranked animal outranks five others, the second-ranked animal outranks four others, and so on.

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.

Jan 10, 2022 · Shape of the hierarchy (a) and individuals' dominance rank (b) for the two wild (Wild1, Wild2) and two captive datasets (C1 and C2; see all 10 captive datasets in electronic supplementary material, S7). The shape of the hierarchy plots the probability (from 0 to 1) for a dominant to win a conflict with respect to the rank difference with its opponent; point size is function of the number of ...
