Group-living animals form dominance hierarchies to share resources. This study models hierarchy formation using a multi-player Hawk-Dove game, where contest success determines resource allocation.

Area of Science:

  • Behavioral Ecology
  • Game Theory
  • Evolutionary Biology

Background:

  • Resource division is crucial for social animals.
  • Dominance hierarchies facilitate equitable resource distribution.
  • Established models often simplify complex social dynamics.

Purpose of the Study:

  • To model dominance hierarchy formation in social animals.
  • To apply a multi-player Hawk-Dove game for resource allocation.
  • To explore emergent properties of hierarchy formation.

Main Methods:

  • Utilized a multi-player extension of the Hawk-Dove game.
  • Simulated pairwise contests within a Swiss tournament.
  • Paired opponents based on prior performance.
  • Allocated resources based on contest won.

Main Results:

  • The model successfully simulates dominance hierarchy formation.
  • Emergent properties align with experimental observations.
  • Resource distribution is directly linked to contest success.

Conclusions:

  • The Hawk-Dove game extension provides a robust framework for studying social hierarchies.
  • This model offers insights into the evolution of resource division strategies.
  • The findings contribute to understanding animal social behavior and resource competition.
