The paper analyzes gene loss in freshwater sticklebacks using a pangenome approach, finding that demographic factors and selection influence gene presence/absence variation.

The paper tests the drift-barrier hypothesis by analyzing mutation rates in nine-spined stickleback populations, finding a negative correlation between mutation rates and effective population size.

The paper identifies a mutation in the MC1R gene responsible for seasonal camouflage in least weasels and shows it was maintained by spatially varying selection.

The paper examines recombination rates and linked selection efficiency in small and large stickleback populations, finding higher recombination in a small freshwater population and a polygenic basis for recombination rates.

The paper estimates de novo mutation rates in three-spined sticklebacks using family trios and finds a mutation rate of 5.05 x 10^-9/bp/gen with a positive correlation between mutation rate and recombination rate.

The paper estimates recent and historical effective population sizes of sticklebacks using genomic data and multiple methods, finding marine populations have the highest Ne values.

SLRfinder identifies candidate sex-linked regions using linkage disequilibrium clustering, outperforming SATC in labile sex chromosomes.

The paper identifies an ongoing sex chromosome turnover in hybridizing stickleback lineages, where younger homomorphic sex chromosomes replace older heteromorphic ones in admixed populations.

The paper investigates introgressive hybridization in nine-spined sticklebacks, finding that selection on introgressed variation varies across genomic regions and that adaptive introgression occurs in response to environmental conditions.

The paper estimates de novo mutation rates in two marine populations of nine-spined sticklebacks using family pedigrees and whole genome sequencing, finding rates lower than commonly used substitution rates.

The paper shows that existing mapping functions fail to predict recombination frequency from map distance in high-density data and proposes a new piecewise function for better accuracy.

The paper analyzes genome sequences of nine-spined sticklebacks to reveal complex population history and its impact on admixture analyses.

The paper improves a stickleback reference genome assembly using Lep-Anchor software, enhancing contiguity and haploidy while reducing haplotypic contigs and detecting more genetic variation.

This study examines genetic introgression in sticklebacks across the Baltic and North Seas, finding that introgression decreases with distance from source populations and shows signs of both neutral and adaptive effects.

The paper presents a high-quality chromosome-level genome assembly of the nine-spined stickleback, revealing evolutionary insights and chromosomal rearrangements compared to the three-spined stickleback.

The paper identifies eQTL and trans regulatory hotspots in threespine stickleback liver tissue, showing complex transcription factor interactions and some links to salinity tolerance.
