| Summary: | Computer experiment study of population evolution and its dynamics is presented for two competing species A and B which share two habitats (1 and 2) of limited environmental capacity. The Penna model of biological aging, based on concept of defective mutation accumulation was adopted for migrating population. In this paper we assume and concentrate on the case when only one species A is mobile. For isolated habitats and for any initial population, we get at equilibrium spatial population distribution (A, B) between the two locations - A occupies location 1 while B-species is present in 2. The effect of migration between habitats is reported for some migration scenarios. With increasing migration we get a sequence (A, B) -> (A, A&B) -> (A, A) -> (B, B) distribution. Another scenarios bring different sequences of population distribution, size and characteristics.
