Parameters Short Definition Standard values applied
G Compound phenotype size; Length of the binary characters that define each pathogen. 30, 40, 50, 60, 70, 80, 100
K Carrying capacity; The pathogen’s maximum population size the host can support 1000, 2000, 3000, 4000, 5000
σ Deviation rate for survivor probability; the higher its value the lower the selection pressure imposed by the host on pathogens 10
b Reproduction rate; average population growth per reproduction step 1.5, 3.5, 5.5, 7.5
μ Novelty rate per locus, probability of trait state change 10-6,10-5,10-4, 10-3, 10-2,10-1, 0.0.
ph Optimum Phenotype imposed by the host G/2
p0 Propagule phenotype. It defines the phenotype distance d0 between propagule and host in the first generation of the colonization (see Eq.1) 0<d0<G/20
N0 Propagule size 1, 10, 50, 100, 200
Maximum number of generations that each simulation was run 1000
Number of simulation repetitions of a given set of parameters. 700
