Code to reproduce the simulations in "Population variability across geographic ranges: perspectives and challenges"

Code to reproduce the simulations in: "Population variability across geographic ranges: perspectives and challenges"
Spat_VarNA.R has the code to reproduce the simulations presented in box 1 that looks at how the shape of the performance curve can lead to different spatial patterns of population variability
Env_Var.R has the code to reproduce the simulations presented in the section "Potential effects of changing environmental conditions on population variability" that looks at how environmental variability affects population variability depending on where a population occurs along the species performance curve
