    "abstract": "The apparent stability of population oscillations in ecological systems is a\nlong-standing puzzle. A generic solution for this problem is suggested here.\nThe stabilizing mechanism involves the combined effect of spatial migration,\namplitude-dependent frequency, and noise: small differences between spatial\npatches, induced by the noise, are amplified by the frequency gradient.\nMigration among desynchronized regions then stabilizes the oscillations in the\nvicinity of the homogenous manifold. A simple model of diffusively coupled\noscillators allows the derivation of quantitative results, like the dependence\nof the desynchronization upon diffusion strength and frequency differences. For\nan unstable system, a noise-induced transition is demonstrated, from extinction\nfor small noise to stability if the noise exceeds some threshold. The coupled\noscillator model is shown to reproduce all previously suggested stabilizing\nmechanisms. Accordingly, we suggest using this model as a standard tool for\nidentification and classification of population oscillations on spatial\ndomains.",
