Female emancipation in a male dominant, sexually dimorphic primate under natural conditions.

open access: yesPLoS ONE, 2021
In most group-living animals, a dominance hierarchy reduces the costs of competition for limited resources. Dominance ranks may reflect prior attributes, such as body size, related to fighting ability or reflect the history of self-reinforcing effects of

Individual history of winning and hierarchy landscape influence stress susceptibility in mice

open access: yeseLife, 2021
Social hierarchy formation is strongly evolutionarily conserved. Across species, rank within social hierarchy has large effects on health and behavior. To investigate the relationship between social rank and stress susceptibility, we exposed ranked male ...

Intersexual Agonism in Gray Langurs Reflects Male Dominance and Feeding Competition

open access: yesFrontiers in Ecology and Evolution, 2022
Male-female agonism varies throughout the primate order with males often dominating females, especially in sexually dimorphic species. While intersexual agonism has been attributed to sexually coercive contexts, it can also occur for other reasons and ...

Sex and dominance: How to assess and interpret intersexual dominance relationships in mammalian societies

open access: yesFrontiers in Ecology and Evolution, 2022
The causes and consequences of being in a particular dominance position have been illuminated in various animal species, and new methods to assess dominance relationships and to describe the structure of dominance hierarchies have been developed in ...

Anal fin pigmentation in Brachyrhaphis fishes is not used for sexual mimicry. [PDF]

open access: yesPLoS ONE, 2018
Mimicry can occur in several contexts, including sexual interactions. In some cases, males mimic females to gain access to potential mates. In contrast, there are relatively few examples of species where females mimic males, and we know very little about

Breeding displacement in gray wolves (Canis lupus): Three males usurp breeding position and pup rearing from a neighboring pack in Yellowstone National Park.

open access: yesPLoS ONE, 2022
Gray Wolves (Canis lupus) are territorial, group living carnivores that live in packs typically consisting of a dominant breeding pair and their offspring.

Assortative mating in fallow deer reduces the strength of sexual selection. [PDF]

open access: yesPLoS ONE, 2011
Assortative mating can help explain how genetic variation for male quality is maintained even in highly polygynous species. Here, we present a longitudinal study examining how female and male ages, as well as male social dominance, affect assortative ...

Infanticide by Adult Females Causes Sexual Conflict in a Female-Dominated Social Mammal

open access: yesFrontiers in Ecology and Evolution, 2022
Infanticide by adult females includes any substantial contribution to the demise of young and inevitably imposes fitness costs on the victim’s genetic fathers, thereby generating sexual conflict with them. Few if any studies have quantified the impact of

Mating first, mating more: biological market fluctuation in a wild prosimian. [PDF]

open access: yesPLoS ONE, 2009
In biology, economics, and politics, distributive power is the key for understanding asymmetrical relationships and it can be obtained by force (dominance) or trading (leverage).

Intraspecific variation in male mating strategies in an African ground squirrel (Xerus inauris)

open access: yesEcology and Evolution, 2022
Male mating strategies respond to female availability such that variation in resources that affect spatial distribution can also alter cost–benefit tradeoffs within a population. In arid‐adapted species, rainfall alters reproduction, behavior, morphology,
