Organisms balance spreading risk in changing environments with adapting to local habitats. This study reveals multiple evolutionary strategies for dispersal and specialization, with one stable outcome.

Area of Science:

  • Evolutionary Biology
  • Ecology
  • Theoretical Biology

Background:

  • Organisms face a trade-off between dispersing to reduce risk and specializing to exploit local resources.
  • Understanding the interplay between dispersal and habitat specialization is crucial for predicting evolutionary trajectories.

Purpose of the Study:

  • To investigate the simultaneous evolution of dispersal and habitat specialization in stochastic environments.
  • To identify evolutionarily stable strategies (ESS) for dispersal and specialization in a two-patch model.

Main Methods:

  • Development of a simple two-patch model.
  • Analysis of evolutionary game theory to determine evolutionarily stable attractors.
  • Simulation of evolutionary dynamics to observe adaptive diversification.

Main Results:

  • Identified multiple locally evolutionarily stable attractors, including specialists, generalists, and dispersal polymorphisms.
  • Demonstrated that typically only one global evolutionarily stable strategy (ESS) exists.
  • Observed evolutionary branching, leading to adaptive diversification.

Conclusions:

  • The interplay between risk spreading and local adaptation shapes the evolution of dispersal and specialization.
  • Evolutionary dynamics can lead to diverse stable states and adaptive diversification through branching.
