|Estimates of ancestral population variability (θ = Neμ), splitting parameter s, post-splitting migration rates (m1 = migration to NWP, m2 = migration to Europe) and parameter of time since divergence (t) obtained from coalescence-based IM model runs of the trans-Arctic clade|
|NW Pacific vs.||θA||1-s||m1||m2||t||(90% HPD)|
|- White Sea groupa||74||0.85%||2.98||0.003||0.44||(0.30–0.63)|
|- White Sea groupb||54||1.85%||1.33||0.138||0.59||(0.56–1.49)|
|- Mezen–Chesha group||83||1.15%||4.99||0.003||0.43||(0.25–1.50)|
The three genetically homogeneous European subgroups were individually compared with the pooled NW Pacific samples. More details in Additional file 3: Table S2.
a Upper limits for prior distribution of θ set to 1000.
b Upper limits for prior distribution of θ were set to θNWP=1000, θEur=100 and θA=100.
