Thread: Periodicity of Lotka-Volterra model

Hello,
Is there a possibility to disorder the periodicity in some predator-prey model?
I'm looking for some example.
What is the reason that could cause the disorder?
What about the system's behaviour after disordering its periodicity?

Thanks...

Two trivial cases:

(a) In absence of predators: .

(b) In absence of preys .

Thanks, FernandoRevilla.
What about the systems behaviour?
For example, in absence of predators, preys populaton will grow up exponentially. Does it mean that periodicity is disordered in that case?
I'm not sure I understood correctly?!

Yes, the solutions are (non periodic). This is different from the standard model:



whose orbits are closed (periodic solutions) with only one equilibrium point at .

Thanks again....
You helped me a lot! :-)
