Hierarchy Establishment from Nonlinear Social Interactions andMetabolic Costs: an Application to the Harpegnathos saltatorArmando SalinasArizona State Universityasalina6@asu.eduKeywords: Harpegnathos saltator, hierarchy, metabolic theory, eusocial insectsAbstract: Many organisms form groups to obtain benefits that they wouldn’t have beenable to accomplish otherwise e.g. improved foraging, predator evasion, and brood care.Theory suggests that increased group size reduces overall metabolic costs, thereby increasingthe efficiency of the group. Furthermore, the notion of group size leads to competition withinthe group for power. These competitions lead to a formation of a hierarchy. To test themetabolic theory, we investigate the hierarchal dynamics and population dynamics of theant species H. saltator. We obtained data from a lab showing the relationship between theratio of reproductive workers and colony size, and we are interested in how it forms. We areinterested on how the colony size of an ant species plays a role in the population dynamics ofthe ant colonies. While there are many previous works that have investigated the hierarchyof H. saltator, we are the first to develop a dynamical system based on intrinsic costs anddemands to model H. saltator hierarchal establishment. We found the equilibria of thesystem and performed sensitivity analysis on it. We also performed bifurcation analysis,and we found that the most sensitive parameter is the cost of being a gamergate.1
