Genealogical asymmetry under the IM model and a two-taxon test for gene flow

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.

Breakups and Hookups: a Markov model for karyotype evolution

The paper develops a Markov model to simulate chromosome evolution through fission and fusion events and compares it to karyotype data across eukaryotic species.

Do chromosome rearrangements fix by genetic drift or natural selection? A test in Brenthis butterflies

The paper investigates whether chromosome rearrangements in Brenthis butterflies fix via genetic drift or natural selection, finding evidence for both mechanisms.

Demographically explicit scans for barriers to gene flow using gIMble

This paper introduces gIMble, a method to identify genomic barriers to gene flow by integrating demographic and selection models, applied to Heliconius butterfly data to reveal both large-effect and polygenic barriers.

Estimating the rates of crossover and gene conversion from individual genomes

The paper introduces heRho, a method to co-estimate crossover and gene conversion rates from individual genomes, showing accurate estimation and potential bias in previous crossover-only models.

Sweeps in time: leveraging the joint distribution of branch lengths

This paper develops a method to identify historically adaptive genomic regions by modeling the timing and context of positive selection, improving power over existing approaches.

The impact of global selection on local adaptation and reproductive isolation.

This study shows that globally beneficial mutations limit local adaptation and delay genome-wide reproductive isolation despite divergent selection pressures.

VolcanoFinder: genomic scans for adaptive introgression

VolcanoFinder detects adaptive introgression using polymorphism data from a single population, identifying volcano-shaped patterns of increased variability around beneficial alleles.
