TABLE 1.

Unscaled parameter estimates (nuA, effective population size of ancestral population; nu, effective population size; m, migration; T, time; s, founding fraction; mutation parameter; Gutenkunst et al., 2009) estimated from the best‐performing demographic models (vic_sec_contact_asym_mig: split with no gene flow, followed by period of asymmetrical gene flow; founder_asym: Founder event with exponential size growth, continuous asymmetric migration; founder_sym: Founder event with exponential size growth, continuous symmetric migration).
