Моделът демонстрира влиянето на стохастичността на околната среда и демографската стохастичност върху популационната динамика.

This is a tandem modified Lotke-Voltera model for a Human/Disease/Nature system. Biocapacity model (land model) replaces exponential growth. Humans with Technology eradicate Disease.

Humans were once the prey of many predators. In this insight, the human death rate is exclusively due to predators and proportional thereto. Predators death rate is exclusively due to famine and humans are their only food. The results is a robust population balance.

Maximum sustainable yield (MSY) for the anchovy.

This is the standard Lotke-Voltera model for a two stock predator prey system. It oscillates given the right settings.
