Geographic distribution of genetic diversity within Iberian Arabidopsis thaliana populations estimated by spatial hierarchical Bayesian modeling. a Distribution of populations with zero (N = 66; absence of genetic diversity) and non-zero (N = 212; presence of genetic diversity) genetic diversity (HS) values. Darker and lighter intensities indicate higher and lower odds for populations with non-zero and zero HS values, respectively. b Distribution of populations with HS values higher than zero (N = 212). Darker and lighter intensities indicate higher and lower HS values, respectively. In both cases, the uncertainty of spatial hierarchical Bayesian model is given as standard deviation units in small maps. Darker and lighter intensities indicate higher and lower uncertainty, respectively
