PRDM9 drives the location and rapid evolution of recombination hotspots in salmonids

This study identifies PRDM9's role in driving recombination hotspots in salmonids, showing rapid evolution and conservation of its function across vertebrates.

Introgression between highly divergent sea squirt genomes: an adaptive breakthrough?

The paper examines introgression between Ciona intestinalis and Ciona robusta in the English Channel, finding a hotspot of recent introgression linked to a cytochrome P450 gene.

Age-specific survivorship and fecundity shapegenetic diversity in marine fishes

This study shows that adult lifespan negatively correlates with genetic diversity in marine fish species, with vital rates explaining observed differences in genetic diversity.

The role of genomic vs. epigenomic variation in shaping patterns of convergent transcriptomic variation across continents in a young species complex

The paper quantifies the relative contribution of genomic and epigenomic variation to convergent gene expression differences in four whitefish species pairs across continents.

Polygenic selection drives the evolution of convergent transcriptomic landscapes across continents within a Nearctic sister-species complex.

The paper investigates convergent transcriptomic landscapes in limnetic and benthic whitefish species pairs across continents, finding shared genomic bases for differential gene expression under polygenic selection.

The role of recombination on genome-wide patterns of local ancestry exemplified by supplemented Brook Charr populations

The paper examines how recombination affects local ancestry patterns in Brook Charr populations following hybridization, finding that deleterious mutations influence introgression dynamics.

The contribution of ancient admixture to reproductive isolation between European sea bass lineages

The paper investigates how ancient admixture with a sister species contributed to reproductive isolation between Atlantic and Mediterranean lineages of European sea bass.

Parallel pattern of differentiation at a genomic island shared between clinal and mosaic hybrid zones in a complex of cryptic seahorse lineages

The paper identifies a genomic island showing parallel differentiation in seahorse lineages across different hybrid zones, suggesting a shared genetic barrier contributes to reproductive isolation in both spatial and ecological contexts.

The divergence history of European blue mussel species reconstructed from Approximate Bayesian Computation: the effects of sequencing techniques and sampling strategies

This study uses Approximate Bayesian Computation to reconstruct the divergence history of European blue mussels, showing that binning strategies in site frequency spectra significantly affect results and that complex gene flow models are preferred.

Analysis of genome-wide differentiation between native and introduced populations of the cupped oysters Crassostrea gigas and Crassostrea angulata

The paper analyzes genome-wide differentiation between native and introduced populations of Crassostrea gigas and C. angulata, showing gene flow in Europe and genomic divergence patterns similar in Asia and Europe.

The origin and remolding of genomic islands of differentiation in the European sea bass

The paper identifies mechanisms behind the formation and remolding of genomic islands of differentiation in sea bass lineages using haplotype-resolved whole-genome sequences.

MODELING THE MULTIPLE FACETS OF SPECIATION-WITH-GENE-FLOW TOWARDS INFERRING THE DIVERGENCE HISTORY OF LAKE WHITEFISH SPECIES PAIRS (COREGONUS CLUPEAFORMIS).

The paper models speciation-with-gene-flow in Lake Whitefish species pairs to infer divergence history and find recent asymmetrical secondary contact and heterogeneous genomic differentiation.
