A single predator multiple prey model with prey mutation

• Investigation uses a discrete model with mutation among prey.
•  Coupled map lattice employed to model mutation.
•  Logistic and Ricker based models used to model prey dynamics.
•  Predation strategy based on predator's focus on prey species.
•  Dynamics studied as mutation rate and focus strength vary.

A multiple species predator-prey model is expanded with the introduction of a coupled map lattice for the prey, allowing the prey to mutate discretely into other prey species. The model is examined in its single predator, multiple mutating prey form. Two unimodal maps are used for the underlying dynamics of the prey species, with different predation strategies being used. Conclusions are drawn on how varying the control parameters of the model governs the overall behaviour and survival of the species. It is observed that in such a complex system, with multiple mutating prey, a large range of non-linear dynamics is possible.
