K_S 20 200 Within-deme carrying capacity used in the Beverton-Holt equation for Ecological Type 1
INITIALINDS 20 200 Initial population size
ENVSCE 0 1 Specifies the environmental scenario to be simulated.
  • 0=Hybrid zone. Starts with two populations, each with an ecological trait at one of the optima
  • 1=No hybrid zone Starts with one population with ecological trait at THETA_E
  • NDEMES 1 100 Number of demes (NDEMESxNDEMES)
    NDIM 1 4 Number of mating criteria
    MMM 1 10 Number of males encountered by each female
    COST 0 100 Cost of mating discrimination
    TOROID 0 1 Boundary condition; 0 = closed boundaries, 1 = toroid boundaries
    MIG_RATE 0 100 Probability of any individual dispersing to an adjacent deme
    MUT_RATE 1 100 Mutation rate for trait loci (x10^(-6))
    MMUT_RATE 1 100 Mutation rate for microsatellite loci (x10^(-3))
    I_M 0 100 Initial phenotype of the m trait
    I_F 0 100 Initial phenotype of the f trait
    I_C 0 100 Initial phenotype of the c trait
    CHOICE 0 4 Mate choice system
  • 0 = Magic-Matching
  • 1 = Arbitrary-Matching
  • 2 = Arbitrary-Open
  • 3 = Magic-Open
  • 4 = Random mating

    B 4 100 Mean offspring per female
    L 1 24 Number of additive diallelic loci influencing each trait
    SIGMA_A 0 100 Variance in mating probability distribution. Larger SIGMA_A implies higher variance and therefore weaker sexual selection

    GENS 1 100000 Number of generations to simulate
    DATA 1 100000 Interval between data collection events
    SAMPLE 100 1000 Number of individuals sampled during data collection
