Falling shoulders ahead: adaptive alien genes are maintained amid vanishing introgression footprint in sea squirts

The paper tracks adaptive introgression between two sea squirt species over time, finding stable core regions but eroding flanking regions of introgressed alleles.

Marine transmissible cancer navigates urbanised waters, threatening to spillover

The paper investigates the spread of a transmissible cancer in mussels, finding higher prevalence in ports and suggesting human activities facilitate its transmission.

Transcriptomics of mussel transmissible cancer MtrBTN2 suggests accumulation of multiple cancerous traits and oncogenic pathways shared among bilaterians

The paper performs transcriptomic analysis of MtrBTN2 transmissible cancer cells to identify oncogenic traits and shared pathways among bilaterians.

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.

An introgression breakthrough left by an anthropogenic contact between two ascidians

The paper investigates hybridization between Ciona species, finding recent introgression of C. robusta into C. intestinalis genomes after human-driven introduction.

Prevalence and polymorphism of a mussel transmissible cancer in Europe

The paper screens European mussels for transmissible cancer lineages, finding low prevalence of MtrBTN2 and polymorphism suggesting complex diversification.

How do species barriers decay? Concordance and local introgression in mosaic hybrid zones of mussels

The paper examines species barrier decay in mussels by analyzing introgression patterns and SNP concordance in hybrid zones.

DILS : Demographic Inferences with Linked Selection by using ABC

DILS performs demographic inferences with linked selection using ABC on population genomic data, identifying models and loci associated with gene flow and population size changes.

The Geometry and Genetics of Hybridization

The paper develops a geometric framework to predict hybrid fitness by decomposing it into intrinsic and extrinsic factors, showing its applicability across population genetic regimes.

Replicated anthropogenic hybridisations reveal parallel patterns of admixture in marine mussels.

The paper studies hybridization patterns in marine mussels caused by human activity, finding repeatable genetic shifts and admixture patterns influenced by genetic background.

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.

Fine-grained habitat-associated genetic connectivity in an admixed population of mussels in the small isolated Kerguelen Islands

The paper investigates genetic connectivity and admixture in Kerguelen mussels, finding that environmental factors better explain population structure than geographic distance.

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.

Coadapted genomes and selection on hybrids: Fisher’s geometric model explains a variety of empirical patterns

The paper develops a fitness landscape model to explain hybridization patterns across species, supported by genomic data from multiple organisms.

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.

Codon usage bias in animals: disentangling the effects of natural selection, effective population size and GC-biased gene conversion

This study investigates codon usage bias in 31 non-model animal species, finding translational selection in large-Ne species and GC-biased gene conversion as a dominant force across all species.
