Table 4 Estimates of ancestral population variability ( θ = N e μ ), splitting parameter s, post-splitting migration rates ( m 1 = migration to NWP, m 2 = migration to Europe) and parameter of time since divergence (t) obtained from coalescence-based IM model runs of the trans-Arctic clade

  1. The three genetically homogeneous European subgroups were individually compared with the pooled NW Pacific samples. More details in Additional file 3: Table S2.
  2. a Upper limits for prior distribution of θ set to 1000.
  3. b Upper limits for prior distribution of θ were set to θNWP=1000, θEur=100 and θA=100.
  4. * The analysis did not converge.
