Self-organized criticality in Monte Carlo simulated ecosystems

Abstract A self-organized critical state is observed in a simple ecosystem model based on a Monte Carlo simulation approach. A 1 ⨍ Fourier spectrum is obtained, related with a dynamical process with fluctuations on a wide range of time scales, showing a well defined power law. The system shows a fractal spatial organization generated from a spatially homogeneous energy flow. Indeed our studies provide evidence for self-organized critically in realistic biological models, showing the reliability of a previous conjecture about the application of this approach to real living systems. Some general implications are also discussed.
