Towards the integration of social dominance and spatial structure
It is shown how individual-oriented (or artificial life) models may provide an integrative background for the development of theories about dominance by including effects of spatial structure in which the effects of winning and losing are self-reinforcing.

Single behavioural differences between egalitarian and despotic animal societies are often assumed to reflect specific adaptations. However, in the present paper, I will show in an
Leadership in fish shoals
Leadership is not an inherent quality of animal groups that show directional locomotion. However, there are other factors that may be responsible for the occurrence of leadership in fish shoals, such
The formation and maintenance of crayfish hierarchies: behavioral and self-structuring properties
Behavioral changes in fighting and the development of dominance relationships were analyzed in groups of juvenile crayfish using quantitative behavioral techniques and linear hierarchies emerged which became increasingly stable over time.
Problems of allometric scaling analysis: examples from mammalian reproductive biology
A new non-parametric line-fitting technique has been developed that eliminates requirements for normality of distribution, greatly reduces the influence of outliers and permits objective recognition of grade shifts in substantial datasets, applied in scaling analyses of mammalian gestation periods and of neonatal body mass in primates.
Artificial Fish Schools: Collective Effects of School Size, Body Size, and Body Form
The approach shows the significance of both self-organization and embodiment in modeling of schools of artificial fish and, probably, in structuring schools of real fish.
Emergent Patterns of Social Affiliation in Primates, a Model
An individual-based model with a high potential for self-organisation is used as a null model to increase the understanding of affiliative behaviour among primates, in particular macaques.
