The paper uses a chromosome-level reference genome to analyze Y-chromosomal diversity in Saimaa ringed seals, finding extreme loss of diversity compared to other ringed seal populations.

The paper uses whole-genome sequencing to study hybridization and genomic differentiation between grey seal subspecies in a contact zone, finding evidence of recent hybridization and local adaptation.

The paper shows Saimaa ringed seals originated 60,000 years ago, long before their lake habitat formed, and have distinct adaptive traits.

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.

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 shows that template-switching mutations generate over 6,000 hairpin structures in primates, leading to 18 new human miRNA genes, 26% of which emerged since primates originated.

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 identifies thousands of mutation clusters in human genomes caused by template switching during DNA replication and develops tools to detect these mutations in sequencing data.

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.
