The Joint Impact of Deleterious Mutations, Dominance, and Gene Flow on Linked Neutral Variation in Structured Populations

The paper investigates how deleterious mutations, dominance, and gene flow affect neutral genetic variation in structured populations using simulations and genealogical analyses.

Unexpected changes in reproductive barriers between incipient species after experimental evolution in sympatry

This study shows that sympatric evolution in spider mites reduced reproductive barriers rather than reinforcing them, suggesting evolutionary changes are driven by non-hybridization-related factors.

Spider mite genotypes with higher growth rate suffer more from competition but exert stronger reproductive interference

The paper examines genetic variation in spider mites, finding that faster-growing genotypes experience more competition but cause stronger reproductive interference.

Interactions between mechanisms of reproductive isolation

The paper models interactions between reproductive isolation mechanisms and finds local adaptation is the most effective barrier, with other mechanisms evolving depending on migration rates.

Dating and quantifying past gene flow due to hybridization events in Iberian chubs

This study dates and quantifies past hybridization events in Iberian chubs using whole genome resequencing data and demographic modeling.

poolHelper: an R package to help in designing Pool-Seq studies

poolHelper simulates Pool-Seq data to optimize study design by evaluating parameter combinations for accurate allele frequency estimation with minimal sequencing effort.

The population history of northeastern Siberia since the Pleistocene

This paper analyzes ancient genomes from northeastern Siberia to reveal complex population migrations and admixture events over the past 40,000 years.
