Adaptive introgression in subdivided populations leaves distinct genomic footprints under global and local selection: a case study in Ciona intestinalis

The paper investigates adaptive introgression in subdivided populations, finding no correlation between adaptive allele frequency and introgressed tract length, suggesting local adaptation rather than a traveling wave.

Navigating between global robustness and fine-scale resolution: the potential of demographic inference based on identical-by-descent segments.

This study evaluates two IBD-based methods for estimating effective density and dispersal variance, finding that IBD-Analysis performs better under spatially homogeneous conditions while MAPS captures spatial patterns but introduces noise in uniform landscapes.

An inversion-rich genome shapes admixture outcomes, generating a mosaic of lineage-specific ancestries in the European sardine

The study identifies inversion-rich genomic architecture in European sardines and shows how chromosomal inversions maintain lineage divergence during admixture.

Integrating genomic and tagging data reveals spatio-temporal population structure in Northeast Atlantic European sea bass

The paper integrates genomic and tagging data to show how seasonal movements shape genetic structure in European sea bass while maintaining demographic subdivision.

Genome divergence between European anchovy ecotypes fuelled by structural variants originating from cross-hemispheric admixture

Comparative population genomics unveils congruent secondary suture zone in Southwest Pacific Hydrothermal Vents

This study uses comparative population genomics to identify a shared phylogeographic break in seven hydrothermal vent species, revealing patterns of lineage divergence and gene flow in the Southwest Pacific.

Sex chromosomes and chromosomal rearrangements are key to behavioural sexual isolation in Jaera albifrons marine isopods

This study identifies sex chromosomes and chromosomal rearrangements as key genomic regions driving behavioural sexual isolation between two marine isopod species.

Divergence and gene flow history at two large chromosomal inversions involved in long-snouted seahorse ecotype formation

The paper characterizes two chromosomal inversions in seahorses and their role in ecotype formation, revealing mechanisms of maintenance and gene flow between them.

Performance and limitations of linkage-disequilibrium-based methods for inferring the genomic landscape of recombination and detecting hotspots: a simulation study

This study evaluates LDhelmet's ability to infer recombination landscapes and detect hotspots under various conditions, finding reasonable correlations but significant limitations in hotspot detection.

Genomic consequences of a recent three-way admixture in supplemented wild brown trout populations revealed by ancestry tracts

The paper examines the genomic impacts of two domestic strain introductions on wild brown trout populations using ancestry tract analysis.

A dense brown trout (Salmo trutta) linkage map reveals recent chromosomal rearrangements in the Salmo genus and the impact of selection on linked neutral diversity

This paper develops a high-density linkage map for brown trout, revealing chromosomal rearrangements and a correlation between recombination rate and nucleotide diversity.
