Abstract:
Harrison et al. [Phys. Rev. E 63, 051905 (2001)] recently proposed that the temporal synchronization and desynchronization between populations in different habitats leads to species coexistence and occurs through a pattern of on-off intermittency. As noise is unavoidable in ecological systems, we show, using the same example, that "attractor bubbling" appears to be another plausible hypothesis to explain the scenario leading to species coexistence. The interest of attractor bubbling in ecology is confirmed by other examples concerning the evolution of intermittent rare species.
