Dominance hierarchy. A high-ranking male mandrill advertises his status with bright facial coloration. [1] In the zoological field of ethology, 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.
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.
