Fig. 3 — The dependence of the optimal trajectories of DVM on $α_{A}$ under the static predation scenario ( $F \equiv 0$ ). We considered the following values $α_{A} = 6, α_{A} = 8, α_{A} = 10, α_{A} = 12, α_{A} = 16$ and $α_{A} = 18$ . The other parameters are $ϕ_{1} = 1, ϕ_{2} = 0.6, ϵ_{A} = 3, ξ = 1, σ = 1, α_{J} = 1.1, β_{A} = 0.05, β_{J} = β_{A} / 5, δ_{A} = 0.1, δ_{J} = δ_{A}, γ_{A} = 0.8, γ_{A} = γ_{J}$
