For example, in a large group with many males, it may be difficult for the highest-ranking male to dominate all the mating opportunities, so some mate sharing is likely to exist. ![]() Hierarchy results from interactions, group dynamics, and sharing of resources, so group size and composition affect the dominance decisions of high-ranking individuals. ![]() Age, intelligence, experience, and physical fitness can influence whether or not an individual deems it worthwhile to pursue a higher ranking in the hierarchy, which often comes at the expense of conflict. These include whether or not high rank gives them access to valuable resources such as mates and food. Given the benefits and costs of possessing a high rank within a hierarchical group, there are certain characteristics of individuals, groups, and environments that determine whether an individual will benefit from a high rank. It has been suggested that decision-taking about the actions of the group is commonly dissociated from social dominance. In birds, dominant individuals preferentially select higher perches to put themselves in the best position to detect and avoid predators, as well as to display their dominance to other members of their own species. In sheep, position in a moving flock is highly correlated with social dominance, but there is no definite study to show consistent voluntary leadership by an individual. However, earlier work showed that leadership orders in goats were not related to age or dominance. He leads the group but shares leadership on a foraging expedition with a mature she-goat who will normally outlast a succession of dominant males. For example, in a herd of feral goats it is a large male that is dominant and maintains discipline and coherence of the flock. In hierarchically social animals, dominant individuals may exert control over others. Wedge-capped capuchins have a clear dominance hierarchyįor many animal societies, an individual's position in the dominance hierarchy corresponds with their opportunities to reproduce. Subordinate animals are opposite their behaviour is submissive, and can be relatively easily influenced or inhibited by other group members. A dominant animal is one whose sexual, feeding, aggressive, and other behaviour patterns subsequently occur with relatively little influence from other group members. Based on repetitive interactions, a social order is created that is subject to change each time a dominant animal is challenged by a subordinate one.ĭominance is an individual's preferential access to resources over another based on coercive capacity based on strength, threat, and intimidation, compared to prestige (persuasive capacity based on skills, abilities, and knowledge). Rather than fighting each time they meet, relative rank is established between individuals of the same sex, with higher-ranking individuals often gaining more access to resources and mates. ![]() In social living groups, members are likely to compete for access to limited resources and mating opportunities. Different types of interactions can result in dominance depending on the species, including ritualized displays of aggression or direct physical violence. A dominant higher-ranking individual is sometimes called an alpha, and a submissive lower-ranking individual a beta. In biology, 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 high-ranking male mandrill advertises his status with bright facial coloration.
