The paper shows that population persistence under gradual environmental change can exhibit bistability, depending on initial population size and genetic variance, beyond just the critical extinction rate.

The paper develops a framework to infer time-varying migration rates by decoupling them from coalescence rates using structured serial coalescent theory.

The paper develops an algorithm to estimate asymmetric migration rates in population genetic models and applies it to datasets from poplar trees, gray wolves, and humans, revealing complex migration patterns.
