    • Abstract:
      The article focuses on a study "Computer Simulation Models: Applications to the Study of Ecological Systems," by Lloyd E. Peppard that was published in the "International Journal of Systems Science." The role of state-space and feedback concepts in the development of simulation models for ecological systems is discussed. The modeling process as applied to ecology is illustrated by the development of models for three ecological systems: the growth of a single species limited by food supply, the competition between two species for a common food supply and a predator-prey relationship. Information available in the literature concerning these systems is used to determine the model structures. Digital simulation results for each model are presented and the effect of parameter variations on model behavior is investigated.
