SHC: SHC

In ashander/phenoecosim: Simulations of eco-evo trait and demographic dynamics under changing environments

Description

SHC

Usage

SHC(sigma_g2, omegaz2, N, R0)

Arguments

sigma_g2	asymptotic genetic variance
omegaz2	defines width of the fitness function $\omega ^2 + 1$
N	census population size
R0	reproductive rate

Details

For this modified SHC after Burger \[ \sigma_SHC(\sigma_g^2) = \fracsigma_g1 + \fracV_s\alpha ^ 2 N_e \] For $\alpha^2$ the variance of the effect of new mutations, $V_m$ the genomic mutation rate per generation, and $N_e \approx 2 R_0 N / (2 R_0 - 1)$. As population size increases, the function approaches a limit of $\sigma_g^2$ $V_s = \omega^2 + \sigma_e^2$ is the width of the fitness function. Hard-coded parameters and $alpha^2 = 0.005$ and $\sigma_e^2 = 1$
