Random walk in genome space: a key ingredient of intermittent dynamics of community assembly on evolutionary time scales.

Abstract excerpt

Community assembly is studied using individual-based multispecies models. The models have stochastic population dynamics with mutation, migration, and extinction of species. Mutants appear as a result of mutation of the resident species, while migrants have no correlation with the resident species. It is found that the dynamics of community assembly with mutations are quite different from the case with...
