Table 1.

Variables and parametrization. All variables and parameters can take continuous values.

initialization constraints during simulations description
parameters
 Std-Dev-environment-change (0.04–1) initialization value determines the degree of environmental stochasticity environmentt + 1 = environmentt + N ∼ (0, Std-Dev-environment-change)
 plasticity-costs (0–1) initialization value determines whether plasticity carries a load reducing odds of survival and reproducing
 mean-mutational-change (0–0.002) initialization value determines both the probability of occurrence of genetic changes and their effect size on the phenotype
emergent values
 environment 0.5 [0,1] expresses the environmental conditions on a single dimension, the same one used to describe the phenotype, the genotype and the plasticity-range
non-plastics and plastics
phenotype 0 phenotypic value expressed in the same dimension as the environment
 genotype 0 in the absence of plasticity, the phenotype = genotype
 match n.a. absolute difference between the phenotypic value and the environmental value; the phenotype is optimized if match = 1
1 - |environment - phenotype|
plastics only
 plasticity-range 0 the maximum phenotypic adjustment that a genotype is capable to increase match
 used-plasticity n.a. 0 ≤ used-plasticityplasticity-range amount of the plasticity-range that is actually used by an individual during development
