Abstract
Stochastic model of migrations of individuals within the limits of finite domain on a plane is considered. It is assumed that population size scale is homogeneous, and there doesn't exist an interval of optimal values of population size (Alley effect doesn't realize for population). For every fixed value of population size number of interactions between individuals is calculated (as average in space and time). Correspondence between several classic models and numbers of interactions between individuals is analyzed.

Keywords stochastic models;migrations;mechanistic models;self-regulative mechanisms.
