Inherits landscape and population
parameters from Standard tab.
Standard model parameters
Dimensions
The number of traits under consideration (1D or 2D).
Initial trait mean (z̄0)
The population mean trait value at the start of simulations.
This description also applies to Initial trait 1 mean (z̄0,1)
and Initial trait 2 mean (z̄0,2) in the 2D model.
Optimum (zopt)
The trait value that grants the highest fitness. This description
also applies to Optimum trait 1 and Optimum trait 2 in the 2D model.
Initial trait st. dev. (σ0)
The population standard deviation in trait values at the start of the
simulation. Increasing this value corresponds to greater initial variation.
For simplicity, the same initial standard deviation is set for both traits
in the 2D model.
Fitness peak width (σs)
Corresponds to the strength of selection.
Larger values mean a wider fitness peak and therefore weaker selection.
Smaller values mean a narrower fitness peak and therefore stronger selection.
Mutational effect (σm)
The standard deviation in the distribution from which trait mutations are drawn.
Increasing this value corresponds to greater mutational effects.
Population size (N)
The number of individuals in the population.
Replicates
The number of replicate simulations to conduct.
Random seed
The random seed can be any integer (42 is common). Setting a random seed
allows for simulation results to be reproducible.
+ Migration model parameters
Migration rate [0,1] (m)
The fraction of the focal population replaced by immigrants each generation.
Immigrant pop. trait mean
The population mean trait value of the population that is immigrating
into the focal population. This description also applies to
Immigrant pop. trait 1 mean and Immigrant pop. trait mean in the 2D model.
Immigrant trait st. dev. (σi)
The population standard deviation in trait values in the population that is immigrating
into the focal population. For simplicity, the same standard deviation is set
for both traits in the 2D model.
