Stochastic effects on biodiversity in cyclic coevolutionary dynamics
Tobias Reichenbach, Mauro Mobilia, Erwin Frey
Abstract
Finite-size fluctuations arising in the dynamics of competing populations may have dramatic influence on their fate. As an example, in this article, we investigate a model of three species which dominate each other in a cyclic manner. Although the deterministic approach predicts (neutrally) stable coexistence of all species, for any finite population size, the intrinsic stochasticity unavoidably causes the eventual extinction of two of them.
