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.

Jan 1, 2021 · In species characterized by single-male groups, the dominance hierarchy describes relationships among the females only (and vice versa), whereas in multi-male/multi-female groups, all adults of one sex are usually dominant over the other (e.g., the more rare female dominance in ring-tailed lemurs; Koyama et al. 2005), and the dominance hierarchies of males and females are often analyzed ...

A linear dominance is achieved when (a) there is any unknown or undefined relationship, for every dyad A and B in the group, either A dominates B or B dominates A, and (b) the dominance order is completely transitive (de Vries 1995).
