Area of Science:

  • Theoretical Biology
  • Computational Neuroscience
  • Animal Behavior

Background:

  • Existing fish schooling models often separate schooling and territorial behaviors.
  • These models typically focus on neighbor influence and probability distributions, failing to explain the duality of attraction and repulsion.
  • The aggregation of animals often involves antagonistic behavioral patterns like attraction and repulsion.

Purpose of the Study:

  • To develop a unified behavior model for fish schooling and territoriality.
  • To explain the duality of attraction and repulsion in animal aggregation.
  • To simulate and validate the model against observed fish behaviors.

Main Methods:

  • Constructed a behavior model based on neighbor state interfaces and state change maps.

  • Utilized a self-similar, nowhere differentiable transition map for temporal construction.
  • Employed computer simulations to test the model against biological schooling and territorial behaviors.

    • Main Results:

    • The model successfully captures the duality of repulsive and attractive forces in fish interactions.
    • Computer simulations demonstrated the model's ability to exhibit both schooling and territorial behaviors.
    • The degree of polarization in schooling behavior was accurately reproduced.

    Conclusions:

    • A single, unified model can explain both fish schooling and territorial behaviors.
    • The proposed interface model effectively represents the complex interplay of neighbor influences.
    • This approach provides a new framework for understanding collective animal behavior and aggregation dynamics.
