Self-limitation, fishing and cannibalism

摘要

A nonlinear continuous predator–prey model is derived for the dynamics of two interacting populations that includes several factors such as self-limitation on the prey, fishing on the predators and cannibalism in the prey of juveniles by adults. The introduction of these factors can account for several important phenomena concerning the dynamics of both populations that have been discussed and studied in the literature. These factors contribute to result in a viable interaction between the two populations in circumstances when their absence would otherwise result in unstable behavior with unbounded oscillations.
