This study shows that higher recombination rates modestly speed up adaptation in populations, primarily by reducing Hill-Robertson interference, with effects varying by demographic history.

This study shows that dysregulated parental care in hybrid stickleback fish leads to reduced offspring survival, suggesting it acts as a postzygotic reproductive isolating mechanism.

The paper updates the pixy software to compute unbiased population-genomic summary statistics from all-sites VCFs, supporting new estimators, ploidy, multiallelic sites, and optimizations.

The paper compares reproductive strategies in stickleback ecotypes, showing how hormonal tradeoffs shape life history divergence through gene expression and androgen production differences.

The paper examines genetic divergence between white and common Atlantic sticklebacks, finding low genomic divergence but distinct reproductive traits, suggesting speciation driven by sexual selection rather than ecological factors.

vcfsim simulates all-sites VCFs with missing data, enabling accurate population genetic studies and benchmarking.

This study examines genomic divergence between two sympatric marine stickleback ecotypes, finding widespread low differentiation and recent divergence with limited gene flow.

The paper introduces pixy, a tool that provides unbiased estimates of genetic diversity and divergence metrics in the presence of missing data.

The paper quantifies recombination rate variation in Drosophila pseudoobscura populations and finds evidence of natural selection driving interpopulation differences.
