In the red fox it has been shown that subordinate individuals, given the opportunity to desert, often do not due to the risk of death and the low possibility that they would establish themselves as dominant members in a new group. This conflict over reproduction in some cases results in a dominance hierarchy. They reasoned that if a primer pheromones were on the bedding then the sub-dominant's reproductive function should continue to be suppressed. In this species, multiple queens of varying sizes are present. "Evidence that primer pheromones do not cause social suppression of reproduction in male and female naked mole-rats". That is, it predicts that one group member's behaviours will elicit a predictable set of actions from other group members.

The same pattern is found in most carnivores, such as the dwarf mongoose. Tiedens and Fragle (2003) found that hierarchical differentiation plays a significant role in liking behaviour in groups. 7 In wild male baboons, the highest ranking male, also known as the alpha, experiences high levels of both testosterone and glucocorticoid, which indicates that high-ranking males undergo higher levels of stress which reduces fitness. Tiedens, Larissa; Fragale, Alison (2003). It has previously been established that the dominance hierarchy within the species is dependent on the highest ranking female (queen) and her ability to suppress critically important reproductive hormones in male and female sub-dominants. 18 In toque monkeys subordinates are often displaced from feeding sites by dominant males.
