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.

This study benchmarks three geometric morphometric methods for analyzing gastropod shell shape, finding that each method has distinct strengths in clustering, interpretability, and efficiency for different research goals.

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 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 uses whole-genome pool-seq data and approximate Bayesian computation to show parallel ecotype formation in Littorina saxatilis across Spain and Sweden despite gene flow.

The paper uses pool-seq data to analyze chromosomal inversions across geographical scales, finding that some inversions contribute to local adaptation to environmental factors like wave exposure and shore height.

poolHelper simulates Pool-Seq data to optimize study design by evaluating parameter combinations for accurate allele frequency estimation with minimal sequencing effort.

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.

The paper identifies candidate barrier loci in wood ants and finds evidence of natural selection and gene flow over time.

The paper examines genomic divergence in Drosophila montana to identify cold adaptation signatures, finding 250 genes with accelerated divergence and outlier loci on the X chromosome.
