It's been 4 years since her previous partner, Akeakamai, disappeared. Now she has a new mate and they've just become parents. We'll know early 2025 if their egg safely hatches

3/ An extinction debt also occurs when gene flow in a metapopulation drops below 1 MPG. This doesn't reflect a deviation from mutation-drift equilibrium, but from migration-drift equilibrium in the metapop. A drop in gene flow reduces the realized inbreeding Ne of the subpopulation.
