  • Scenario 1a, mild bottleneck in the pelagic lineage (Ne 1–25,000), and strong bottleneck in the demersal lineage (Ne 1–1,000); scenario 1b, mild bottleneck in the Pelagic lineage (Ne 1–25,000), and mild bottleneck in the demersal lineage (Ne 1,000–10,000); scenario 1c, no bottleneck in the pelagic lineage, and strong bottleneck in the demersal linage (Ne 1–100); scenario 1d, no bottleneck in the pelagic lineage and mild bottleneck in the demersal lineage (Ne 1,000–10,000); scenario 1e, no bottleneck.
