Synchronous dispersal in metapopulations can lead to complex dynamics, including multiple attractors. Dispersal can even shift local patch dynamics between compensatory and overcompensatory states.

Area of Science:

  • Ecology
  • Mathematical Biology
  • Population Dynamics

Background:

  • Metapopulation dynamics are crucial for understanding species persistence.
  • Local patch dynamics can be compensatory or overcompensatory.
  • The role of synchronous dispersal in these systems is not fully understood.

Purpose of the Study:

  • To explore the effects of synchronous dispersal on discrete-time metapopulation dynamics.
  • To investigate how different types of local patch dynamics (compensatory, overcompensatory, mixed) influence metapopulation behavior.
  • To analyze the emergence of multiple attractors and complex basin structures.

Main Methods:

  • Development of discrete-time metapopulation models.
  • Analysis of single-species models with compensatory and overcompensatory local dynamics.

  • Examination of mixed systems incorporating both compensatory and overcompensatory patches.
  • Investigation of the impact of synchronous dispersal on model attractors and basin structures.

    • Main Results:

    • Single-species metapopulation models with only compensatory dynamics behave like single-patch models.
    • Overcompensatory dynamics in some patches lead to multiple attractors with complex, intermingled basins of attraction due to dispersal.
    • In mixed systems, synchronous dispersal can alter local dynamics, switching them between compensatory and overcompensatory states.

    Conclusions:

    • Synchronous dispersal significantly impacts metapopulation dynamics, especially when overcompensatory mechanisms are present.
    • The interplay between dispersal and local dynamics can create complex ecological behaviors, including bistability or multistability.
    • These findings highlight the importance of considering dispersal synchrony and local density dependence in ecological modeling.
