KEY WORDS: single population, individual-based model, classical model.

Abstract: Individual-based models describe interactions between individuals in the population. Dynamics of the number of individuals in the population is a byproduct of these interactions. Individual variability plays an important role in this type of models. Individual-based models can be formulated in the form in which individual variability is replaced by average values. In contrast, classical models describe dynamics of population density directly and assume that all processes in the populations can be expressed as functions of the density. Numerical results of classical and individual-based models can be similar but interpretations almost always are different.
