Positive frequency dependence, previously thought to harm rare types, surprisingly promotes species coexistence. This occurs through stable banding patterns, enhancing coexistence even with disturbances.

Area of Science:

  • Ecology
  • Theoretical Ecology
  • Mathematical Biology

Background:

  • Interspecific interactions often drive species coexistence through negative frequency dependence.
  • Positive frequency dependence is typically associated with the extinction of rare types, not coexistence.

Purpose of the Study:

  • To investigate the role of positive frequency dependence in species coexistence using a novel modeling approach.
  • To explore how spatial scales of frequency dependence and dispersal influence coexistence dynamics.

Main Methods:

  • Development of a stochastic cellular automata model.
  • Simulation of interactions with varying scales of frequency dependence and dispersal.
  • Analysis of banding pattern formation and stability over time.

Main Results:

  • Positive frequency dependence significantly enhances species coexistence beyond random chance.
  • Stable banding patterns emerge, contributing to long-term coexistence.
  • Coexistence is promoted by positive frequency-dependent interactions at local spatial scales, outperforming neutral interactions.
  • Results remained robust across varied boundary conditions and disturbance levels.

Conclusions:

  • Positive frequency dependence can be a significant factor in promoting species coexistence.
  • The spatial scale of interactions is crucial, with local positive frequency dependence being particularly effective.
  • Increased strength of positive frequency-dependent interactions consistently enhances coexistence.
