Summary: Rhesus macaques are bred for biomedical research and their strict dominance hierarchy leads to a high rate of fight injuries. This study analyzed 10 years of injury records and found that breeding females were more likely to be injured. The introduction of a new adult male had the greatest impact on injury rate and pregnancy probability for females.

Summary: Male vulturine guineafowl strategically exhibit higher-cost aggressive interactions toward individuals with lower ranks, while lower-cost aggressive interactions are directed toward individuals further down the hierarchy. These results support the hypothesis that the costs associated with different interaction types can determine their expression in social groups with steep dominance hierarchies.

Summary: Prestige-biased social learning occurs when individuals prefer to learn from prestigious group members. While previous research has confirmed the adaptive use of prestige-bias, the domain-specificity and generality of this bias has not been explicitly addressed experimentally.Results from an online experiment suggest that individuals overwhelmingly prefer domain-specific prestige cues, but also show a preference for domain-general cues when only cross-domain cues are available. This indicates that people may vary in the extent to which they employ domain-specific or domain-general prestige-bias depending on their experience and understanding of different domains.

Summary: Dominance hierarchies can provide benefits depending on ranks, and rank can emerge from a group's social history. In this study, we investigated rank dynamics in captive monk parakeets and found that social history shapes rank emergence. After reintroduction, no individuals could immediately regain their previous rank, and top-ranked birds showed greater rank loss. Bodyweight was also found to be unassociated with rank.

Summary: The study found that social experience positively influences contest success in male domestic fowl, but aggression and morphological traits also play an important role.

Summary: This study examines the party attendance behavior of male chimpanzees and its association with social factors such as male dominance rank and aggression. The results show that low-ranking males spend more time alone to avoid aggression, unless there are mating opportunities. Additionally, aggression increases with the number of males in the party, and low-ranking males receive more aggression than higher-ranking males.

Summary: The study found that adolescent male chimpanzees primarily use aggression towards females to establish social dominance rather than for sexual coercion, unlike adult males. They were able to dominate all adult females before or soon after dominating their first adult male, and the order of dominance over females was consistent with the females' hierarchy rankings.

Summary: This study examined the influence of early and adult management factors on aggressive behavior in cats, finding that female cats were more likely to show aggression towards their owners, while households with three or more cats and owners using positive reinforcement had lower odds of aggression. Additionally, aggression towards novel people, objects, and situations was more prevalent when owners used positive punishment.

Summary: The presence of wildlife in urban spaces is a global phenomenon with individual differences in response to management interventions, particularly in adult male baboons. Focusing management efforts on adult males may inadvertently allow socially peripheral female baboons greater access to urban spaces.

Summary: Vocalizations are important signals for group-living animals during agonistic interactions, and this study on ring-tailed lemurs found that different vocalizations were used for aggressive or submissive interactions by males of varying dominance ranks and ages.

Summary: This study investigates the effects of androstadienone, a potential human sex pheromone, on aggression. The results show that smelling androstadienone reduces both reactive and proactive aggression in men, but increases reactive aggression in women.

Summary: This study examined the impact of post-orchiectomy inflammation on social dynamics in Nelore bulls in Brazil. The results showed a close association between the severity of post-surgical inflammation and changes in social hierarchy, potentially due to the effects of pain on social relations.

Summary: Individuals in dominant and subordinate positions in social hierarchies exhibit different behaviors, physiology, and neural functioning. Dominant animals display higher levels of dominance behaviors and reproductive behaviors, while subordinate animals inhibit these behaviors and adapt to socially stressful contexts. These changes may have short-term benefits but pose long-term challenges to health. Additionally, rapid changes in social ranks are associated with dynamic modulations in the brain and periphery.

Summary: This focused review introduces the ubiquity of dominance across the animal kingdom and the modern approach of measuring dominance using Percolation and Conductance (Perc). Perc takes into account the nonlinear hierarchical structure and provides a complementary metric of 'dominance certainty' to assess the degree of ambiguity in rank relationships. The review summarizes studies on the importance of 'dominance certainty' in large captive rhesus macaque breeding groups and concludes with suggestions for future research directions in dominance hierarchy.

Summary: The use of sand as environmental enrichment in the rearing conditions of Senegalese sole promotes dominance behavior and upregulates brain gene expression, which may enhance fish welfare and advance future maturation.
