This study identifies 18 chromosomal inversions in Littorina saxatilis that respond to environmental variation and influence phenotypic traits, explaining 15% of phenotypic variation.

The paper compares genetic differentiation and inversion patterns in snail ecotypes across two hybrid zones, finding shared and site-specific genomic architectures for adaptation to wave exposure.

The paper establishes a genetic baseline for Atlantic cod in Sweden using a SNP panel to monitor population structure and genetic diversity.

The paper compares parallel ecotypes of Littorina saxatilis in Spain and Sweden to assess divergence in gene flow, finding stronger reproductive isolation in Spain despite similar phenotypic divergence.

The paper predicts rapid temporal adaptation in marine snails using spatial genetic and phenotypic variation from a 30-year transplant experiment, finding observed changes align with predictions.

This study presents a chromosome-scale genome assembly of the brittle star and identifies conserved gene expression patterns during regeneration across invertebrates and vertebrates.

This paper presents a new chromosome-scale genome assembly of Littorina saxatilis with improved contiguity and completeness, enabling better study of chromosomal inversions and their role in speciation.

The paper identifies 12 chromosomal inversions that strongly couple reproductive barriers between ecotypes of Littorina fabalis, maintaining genetic integrity despite hybridization.

The paper analyzes the microbiome of wrackbeds and seaweed flies along the North Sea-Baltic Sea transition, finding shifts in microbial communities and functionality linked to polysaccharide degradation.
