Supplementary Materials

This PDF file includes:

  • Supporting text
  • Table S1. Summary of state variables and model parameters.
  • Fig. S1. Example of canonical Red Queen dynamics (Red Queen n-ary oscillations) where all host and parasite types undergo dominance switching.
  • Fig. S2. Oscillatory behavior expected to occur when α has a lower value (that is, there is a higher level of parasite specificity).
  • Fig. S3. Parameter diagram showing the effects of increasing the host’s carrying capacity K on the oscillation patterns of host and parasite population densities (σ = 0, t = 0 to 50,000).
  • Fig. S4. Increasing the carrying capacity K increases the amplitude of population density (for example, compare the graphs associated with K = 3 and K = 10; σ = 0).
  • Fig. S5. Host population density time series showing the effects of stochastic noise (n = 4, K = 16).
  • Fig. S6. Host population pattern illustrating the effects of stochastic noise on a system with 10 host types and 10 parasite types (K = 40, σ = 10%).
  • Fig. S7. Additional illustrations of some population dynamics that can arise from our host-parasite interaction system (σ = 0).
