Three models were run for each regional grouping of Alps, Harz, Northeast, and Northwest (population). Model refers to one of three model types: Null model of constant population size (Null), instantaneous size change/bottleneck (BOT), and ISC. Parameters were estimated for contemporary Ne (NeCON), ancestral Ne (NeANC), Ne during bottleneck (NeBOT), and time of bottleneck in number of generations (TBOT). Model fit and selection criterion are shown as delta likelihood, calculated as maximum estimated likelihood maximum observed likelihood (ΔL), AIC, and ΔAIC.
