Dominance style, differences between the sexes and species: An agent-based model

摘要: In recent studies of primates, the question has been raised whether competitive regimes (egalitarian versus despotic) are species-specific or should rather be considered as sex-specific. To study this problem we use an individual-oriented model called DomWorld in which artificial agents equipped merely to group and compete. former model, dominance style appeared strongly influenced by intensity aggression: increasing only aggression, a great number characteristics egalitarian society switched those despotic one. Here, investigate, using DomWorld, regime males females that differ exclusively their fighting capacity; having higher aggression initial capacity winning, such may due male-biased sexual dimorphism. Unexpectedly it appears that, even if is greater than females, hierarchy still significantly weaker thus less differentiated more females. The explanation (compare larger body size), single events victory defeat lead differentiation among difference between sexes behave themselves compared behaviour themselves. These effects already visible during phases hierarchical development. results resemble findings primates; real primates degree dimorphism influence each sex.
