A 7-year study of brown hyaenas of the Central Kalahari, Botswana, showed a separate, linear dominance hierarchy within each sex. The highest-ranking female shared equal rank with the alpha male, and she had the highest feeding time of all clan members. The immigrant alpha male was dominant over all other clan females and all natal males. The advantages of high rank for clan females were (1) increased feeding time at carcasses, (2) the opportunity to remain in the clan and rear cubs in the… Expand

The reproductive behavior of the spotted hyena is particularly fascinating as it is linked to a suite of unusual traits, including a penile clitoris that resembles the male phallus, through which females copulate and give birth, social dominance of natal females over immigrant males, and immigrant males that form social queues rather than using aggression to advance their social status.

Social dominance and breeding success in captive brushtail possums,Trichosurus vulpecula
The effect on breeding success in captive groups of possums of vasectomising the dominant male is described and dominance status remained unchanged after treatment but there were no further births, whereas young continued to be born in pens where males were untreated. Expand
Female dominance in two basal primates, Microcebus murinus and Microcebus lehilahytsara: variation and determinants
It can be concluded that female dominance probably represents an ancestral trait in mouse lemurs and it is proposed that its evolution might have been driven by sex-specific energetic constraints prevailing in the species-specific ancestral habitats, and may moreover be influenced by thespecies-specific social organization.

Dominance rank relationships among wild female African elephants, Loxodonta africana
Socioecological models of the evolution of female-bonded societies predict a relation between resource distribution and the nature of female affiliative and dominance relationships. Species thatExpand
Benefits and Costs of Dominance in the Angelfish Centropyge bicolor
It is suggested that in C. bicolor, the primary benefit of high rank is increased reproductive success in terms of current spawning frequency and the prospect of inheriting the male position in the near future, which may be traded off against the cost of aggressively defending rank and territory.

Microsatellite Variation in Namibian Brown Hyenas (Hyaena brunnea): Population Structure and Mating System Implications
Examination of genotyped brown hyenas from the west coast of Namibia indicates that dominant males were not related to dominant females and that there is multiple paternity within clans. Expand

Endocrine profiles and social interaction in the ringtailed lemur (Lemur catta), a species characterized by extreme masculinization of the female, are examined to search for a potential source of circulating androgen in adult females and an endocrine correlate of female dominance or its proxy, aggression.

Human-brown hyaena relationships and the role of mountainous environments as refuges in a postcolonial landscape
Humans and brown hyaenas (Hyaena brunnea) frequently interact within a shifting landscape of conflict and cohabitation, yet the social and biological dimensions of these relationships, particularlyExpand
Patterns of scat deposition by brown hyaenas Hyaena brunnea in a mountain savannah region of South Africa
Abstract The brown hyaena Hyaena brunnea is a near threatened large carnivore inhabiting sub-Saharan Africa. Like many other species of terrestrial carnivores, brown hyaenas often and repeatedlyExpand
Testosterone predicts future dominance rank and mating activity among male chacma baboons
The results support the challenge hypothesis with males exhibiting elevated testosterone in association with the acquisition of high rank (ensuring access to mates), rather than with mating itself, and testosterone levels predicted future, rather than current, mating activity. Expand
