Fig. 2

Host dynamics in the a absence and b presence of defensive microbes. Without defensive microbes, the parasite negatively affects host dynamics albeit in a time-lagged way (mediated through the scaling equation (Eq. 3)). Defensive microbe based immunity can reduce the parasite infectivity and, lead to contrasting dynamics in which hosts show sustained population-level growth. (Parameter values: r=2.0, μ=0.9, λ=0.1, γ=0.5, β 1=0.05, β 2=0.1, μ P =0.01, μ Dm =0.01, r Dm =1.5, K Dm =150, Δ T=t/n=0.0001)
