The limiting conditional distribution of tumor size is in good agreement with epidemiologic data on advanced lung cancer. Elsevier Science Inc. All rights reserved. The dynamics of a predator-prey system, where the predator has two stages, a juvenile stage and a mature stage, are modelled by a system of three ordinary differential equations. The mature predators prey on the juvenile predators in addition to the prey. Numerical studies indicate that a stable limit cycle appears.
Cannibalism can therefore be a destabilizing force in a predator-prey system.
