Atlantic cod (Gadus morhua) ecotypes, not inversion frequencies, underlie divergence in egg buoyancy distribution

The paper tests whether inversion genotypes or ecotype background drive differences in egg buoyancy in Atlantic cod, finding ecotype has a stronger effect.

Female-biased sex ratios despite stable genetic sex determination across a climatic gradient in a marine fish

The paper investigates adult sex ratio bias in a marine fish across a climatic gradient, finding female bias arises from ecological factors rather than genetic or environmental sex determination.

Chromosomal inversions assist acute salinity and temperature adaptation in Atlantic cod (Gadus Morhua) eggs

This study shows chromosomal inversions in Atlantic cod eggs help adapt to short-term temperature and salinity stress.

Connectivity and population structure in a marginal sea - a review

This review examines connectivity and population structure of marine species in the Skagerrak, finding high but asymmetric connectivity and distinct populations linked to coastal complexity and barriers to gene flow.

Mixed origin of juvenile Atlantic cod (Gadus morhua) along the Swedish west coast

This study genetically identifies juvenile Atlantic cod ecotypes along the Swedish west coast, revealing coastal dominance in inshore areas and offshore dominance in deeper waters.

Comparison of de novo and reference genome-based transcriptome assembly pipelines for differential expression analysis of RNA sequencing data

The paper compares de novo and reference genome-based transcriptome assembly pipelines for differential expression analysis in Atlantic cod, finding that Trinity offers higher sensitivity for detecting biologically meaningful expression differences, while the new Tuxedo pipeline provides higher quality assembly.

Finding coarse and fine scale population structure in a coastal species: population demographics meets genomics

This study identifies genetic structure at multiple scales in black goby populations along the Norwegian coast using genomic and oceanographic data.
