This study extends the hitch-hiking model to evolutionary rescue, showing how demographic feedback affects genetic signatures compared to constant population size sweeps.

The paper examines how evolution during extreme events affects population persistence, finding that heritability and phenotypic variance influence extinction risk depending on event duration and severity.

This study uses Fisher's geometric model to show how the genetic path to evolutionary rescue shifts from single to multiple mutations as mutation rates and environmental stress increase.

This study shows that cooperation can either help or hinder population adaptation to environmental change, depending on whether cooperation costs reduce fecundity or viability.

This paper investigates how genetic parallelism and speciation progress under different directions of natural selection, finding that small directional differences reduce parallelism and affect hybrid fitness differently under parallel vs. divergent selection.

This study uses population genetic models to show that haploid selection and sex ratio biases can drive transitions between sex-determining systems, challenging previous theories that focused on sex ratio equalization.
