Title | The effect of habitat fragmentation on cyclic predator-prey populations |
Abstract | It is well-known that predator prey populations can exhibit regular, large-amplitude cycles, and existing models suggest that this behaviour is due to a predator-prey limit cycle. We will examine the effect of habitat fragmentation on the predator-prey cycles by adding diffusion to existing models, and examining solution behaviour on a domain consisting of alternating good and bad habitat patches. We will see that habitat fragmentation tends to decrease cycle amplitude, though the pattern of decrease is very model dependent. Numerical results and theoretical arguments will be presented. |
