Abstract: Sociality often involves conflict as individuals compete with group members for resources. In many species, including humans, individuals assort into dominance hierarchies. Individuals with more social information may be able to better optimize which individuals… read more here.

Abstract: Significance In animal conflict, the more information individuals have about their social world the better decisions they can make about whom to fight. Determining what animals “know,” however, has proved difficult. We reverse-engineer how information… read more here.

Abstract: A century ago, foundational work by Thorleif Schjelderup-Ebbe described a ‘pecking order’ in chicken societies, where individuals could be ordered according to their ability to exert their influence over their group-mates. Now known as dominance… read more here.

DOI: 10.1098/rstb.2020.0444
Abstract: Across species, animals organize into social dominance hierarchies that serve to decrease aggression and facilitate survival of the group. Neuroscientists have adopted several model organisms to study dominance hierarchies in the laboratory setting, including fish,… read more here.

DOI: 10.1098/rstb.2020.0449
Abstract: Size-based dominance hierarchies influence fitness, group size and population dynamics and link dominance structure to evolutionary and ecological outcomes. While larger individuals often gain dominance, social status may influence growth and size in return, resulting… read more here.

New Insights into the Male Morphotypes of the Amphidromous Shrimp Macrobrachium olfersii (Weigmann, 1836) (Caridea: Palaemonidae) and a Discussion on Social Dominance Hierarchies.

Abstract: Male morphotypes in a population may lead to the development of social dominance hierarchies in crustacean species. Currently, Macrobrachium is the decapod crustacean genus with the largest record of species that present the development of… read more here.
