Experimental evolution unveils a role for structural variants and sex-specificity in the genetic architecture of lifespan

This study uses experimental evolution in seed beetles to show that structural variants and sex-specific genetic factors influence lifespan evolution.

Population genomics reveal genetic variants associated with lunar-regulated spawning time in grass puffer

The paper identifies genetic variants associated with lunar-regulated spawning time in grass puffer fish by analyzing geographic differences in spawning timing and conducting population genomics.

Unheralded high MHC Class II polymorphism in the abundant Atlantic herring resolved by long-read sequencing

This study identifies highly polymorphic MHC class II genes in Atlantic herring using long-read sequencing, revealing exceptional diversity and coevolution of gene pairs.

upSPLAT: Early-Barcoded Library Preparation for Cost-Effective Population-Scale Genomics

upSPLAT reduces library preparation costs by 10-fold through early barcoding and single-stranded ligation, enabling cost-effective, high-plex sequencing across diverse DNA inputs.

Whole genome sequencing reveals how plasticity and genetic differentiation underlie sympatric morphs of Arctic charr

The paper uses whole genome sequencing to analyze genetic differentiation and plasticity in sympatric morphs of Arctic charr across multiple lakes, revealing a polygenic basis and varying levels of reproductive isolation.

Evolution of fast-growing piscivorous herring in the young Baltic Sea

This study shows that piscivorous herring evolved sympatrically in the young Baltic Sea, growing faster and occupying a new niche despite incomplete adaptation to a fish diet.

Limited parallelism in genetic adaptation to brackish water bodies in European sprat and Atlantic herring

The paper analyzes genetic adaptation in European sprat and Atlantic herring to brackish waters, finding limited parallelism in genetic changes despite similar environmental pressures.

Copy number variation and elevated genetic diversity at immune trait loci in Atlantic and Pacific herring

This study identifies copy number variation and high genetic diversity at immune-related loci in herring, showing these regions are blind spots in short-read genome scans.

Conservation of affinity rather than sequence underlies a dynamic evolution of the motif-mediated p53/MDM2 interaction in teleosts

The paper investigates the evolution of p53/MDM2 interaction in teleosts, finding that affinity is conserved through compensatory changes in both conserved and non-conserved regions.

The genomic basis and environmental correlates of local adaptation in the Atlantic horse mackerel (Trachurus trachurus)

The paper examines genomic variation in Atlantic horse mackerel to identify adaptive loci and environmental drivers of local adaptation, finding chromosomal inversions and gene expression differences related to environmental factors.

A chromosome-level assembly of the Atlantic herring - detection of a supergene and other signals of selection

The paper presents a chromosome-level genome assembly of Atlantic herring, enabling the detection of a supergene and improved analysis of selection signals.

Moderate Nucleotide Diversity In The Atlantic Herring Is Associated With A Low Mutation Rate

The paper estimates the mutation rate in Atlantic herring and explains its moderate nucleotide diversity despite large population size.

A Model-Free Approach For Detecting Genomic Regions Of Deep Divergence Using The Distribution Of Haplotype Distances

HaploDistScan detects genomic regions of deep divergence using haplotype distances without prior population information, identifying balancing selection in ruff and Darwin's finch data.
