【 摘 要 】

In the present work, the models of dynamics ecological populations were described. The development of the models, in order to describe these populations was presented. They have evolved from an independent way to the models that represent the evaluation of epidemiology in humans. The differential equations that describe the relationships prey-predator, crop-pest and migration effect were shown. It was also described the possibility to represent these models by means of equations in difference and computerized simulation systems. The interconnection between a mathematical model and the ecosystem stability according to the biological parameters was showed. Ecological questions that can be answered analyzing the models were approached.
