Figure 6From: Patterns of genetic variation in populations of infectious agentsLevel of differentiation. The level of differentiation among hosts measured as F ST . The empty symbols denote the results for the island model, while the full symbols correspond to scale-free networks. The parameters are e = 0.01 (circles) and e = 0.02 (triangles), D = 1000, N d = 10, n t = 50, n d = 5 and μ = 0.0004.Back to article page
