The effect of varying handling time and attack rate on host-pathogen dynamics. In general, cycle lengths increase when a handling time is longer. With a short handling time aggressive consumers make the system disease free, whereas almost all hosts are infected if the handling time is long. (a) Areas of different dynamics with the consumer dispersal rate of 0.25 (a large value selected to maximize the effect). (b) Areas of various dynamics with respect to the host dispersal rate of 0.1. While parameter values κ = 4 and λ = 0.5 were used to produce contrasting patterns, a large range of κ and λ values produces similar dynamical partitions. The dotted line describes a gradual shifting from one dynamics to another and solid borders show an abrubt change in a dynamical behavior. The drawn plots are based on simulation runs with a single representative initial value setting (S 1 = 90, I 1 = 0, P 1 = 100, Q 1 = 200, S 1 = 10, I 1 = 0, P 1 = 100, Q 1 = 10). Initial values have influence on shifts between different dynamics and therefore these plots give only approximate dynamical ranges. Hence, near the border area of two different dynamics, the system may end up either of stabilized dynamics depending on the initial balance between different populations.
