Level of differentiation between hosts. The level of differentiation between pairs of hosts, F _ST , as a function of their topological distance (which is estimated as the minimum number of links which separates two distinct demes). A scale-free network, with γ = 3, is considered with D = 500, N _d = 10, μ = 0.0008, e = 0.01. R₀ = 3 in filled circle symbols, R₀ = 30 in empty circle symbols and R₀ = 60 in diamonds.
