This study identifies centromeric repeat turnovers in Arabidopsis species, revealing evolutionary mechanisms and the role of genetic drift and centromere drive in repeat replacement.

The paper analyzes genome-wide genealogies to detect ancient gene flow from a super-archaic lineage using integer partition distributions.

This study estimates the reduction in genetic diversity from background selection in populations with non-equilibrium demography and partial selfing, finding weak effects in outcrossers and stronger effects in selfers.

This paper introduces a new statistic, Am, to detect gene flow between populations using genealogical asymmetry under the isolation-migration model, validated with simulations and applied to Heliconius butterflies and Odocoileus deer.

The paper studies neo-sex chromosome evolution in butterflies, finding that rare recombination can reverse degradation and create divergence plateaus on neo-W chromosomes.

This study examines genetic diversity in European butterflies and finds it correlates with body size and genetic map length, not population size or fecundity.
