We extend a model of community isolation in the d-dimensional lattice ontothe case with an imposed imbalance between birth rates of competingcommunities. We give analytical and numerical evidences that in the asymmetrictwo-specie model there exists a well defined value of the asymmetry parameterwhen the emergence of the isolated (blocked) subgroups is the fastest, i.e. thecharacteristic time tc is minimal. This critical value of the parameter dependsonly on the lattice dimensionality and is independent from the system size.Similar phenomenon was observed in the multi-specie case with a geometricdistribution of the birth rates. We also show that blocked subgroups in themulti-specie case are absent or very rare when either there is a strictlydominant specie that outnumbers the others or when there is a large diversityof species. The number of blocked species of different kinds decreases with thedimension of the multi-specie system.
