The Mapogos first pride clash was in 2006. The Mapogo lions entered the northern Sabi Sand, which was ruled by four dominant males. Immediately upon arrival, the Mapogos managed to kill one of the males, and the remaining three were driven off. [11] With the Ottawa pride's male lion driven off, three lionesses and 11 cubs remained.
Gaining dominance, that is becoming the alpha male, results in an "increased testicular volume, reddening of sexual skin on the face and genitalia, and heightened secretion of the sternal cutaneous gland". [13] When a male loses dominance or its alpha status, the reverse happens, although the blue ridges remain brightened.
The complex relationship between rank and reproduction in this species is likely explained by the fact that rhesus macaques queue, rather than fight, for dominance, meaning that the alpha male is not necessarily the strongest or most attractive male. [16] [17] In rodents, the highest-ranking male frequently sires the most offspring.

Elephants can use their ears as threat displays in male-to-male competition. Sexual selection in mammals is a process the study of which started with Charles Darwin's observations concerning sexual selection, including sexual selection in humans, and in other mammals, [1] consisting of male–male competition and mate choice that mold the development of future phenotypes in a population for a ...
The key to this hypothesis is that dominant male is the newest member of the coalition. Since, the subordinate males have lived together prior to the dominant male's arrival, researchers suggest that such cohabitation has allowed the baboons to come to a mutual “agreement” that they will work together to overturn the dominant male.

Lions of the same gender are incredibly affectionate with each other, and they regard each other as lifelines, he said. Even groups of two or three males have a much better life expectancy, and ...
In this system, power is not ultimate; it is partially mitigated by cooperation among subordinate individuals. Another form of dominance structure is related to age. For example, some gorillas demonstrate an age-graded dominance structure: wherein the eldest male member is the highest-ranking dominant male (or alpha). [1]
