Best fit models for coalescent analysis of Ifremeria nautilei populations among Manus, North Fiji, and Lau Basin.
| Population 1 | Population 2 | θ 1 | θ 2 | θ a | m1 | m2 | τ | /τ μ 1 *404 | τ/μ 2*404 |
|---|---|---|---|---|---|---|---|---|---|
| Manus | North Fiji | 59.3 | 23.3 | 0.1 | 0.0 | 0.0 | 2.09 | 103,000 | 345,700 |
| Manus | Lau | 66.0 | 12.6 | 0.4 | 0.0 | 0.0 | 1.55 | 79,900 | 256,400 |
| Lau | North Fiji | 66.9 | 66.9 | 6.7 | 6.2 | 27.2 | 0.25 | 12,400 | 41,400 |
θ1 = effective size of population 2, θ2 = effective size of population 2, θa = effective size of ancestral population, m1 = migration into population 1 from population 2, m2 = migration in to population 2 from population 1, τ = splitting time between populations. Splitting time is calibrated against two mutations rates: μ1 = 5 × 10-8 [21], μ2 = 1.5 × 10-8 [76] adjusted for the number of base pairs in the sequence. Posterior probability densities are provided in Additional File 2, Figure S1.
