An old inversion polymorphism involving giant mobile elements in an invasive fungal pathogen

The paper identifies a non-recombining genomic region in the invasive fungus Cryphonectria parasitica linked to the mating-type locus, showing balanced haplotype segregation and potential adaptation through mobile elements.

Repeated loss of function at HD mating-type genes and of recombination suppression without mating-type locus linkage in anther-smut fungi

The paper shows that HD mating-type genes have lost function in three Microbotryum species, with PR genes controlling mating compatibility, and reports evolutionary strata from recombination suppression.

Subtle introgression footprints at the end of the speciation continuum in a clade of Heliconius butterflies

The paper examines gene flow and speciation in Heliconius butterflies, finding limited introgression and stronger genomic signatures in mimetic populations.

Allele surfing causes maladaptation in a Pacific salmon of conservation concern

This study shows that allele surfing during postglacial expansion in Coho salmon increases deleterious mutation load and reduces selection efficacy, influenced by population size, recombination rates, and chromosomal inheritance.

Population genetics reveals divergent lineages and ongoing hybridization in a declining migratory fish species complex

This study uses population genetics to reveal divergent lineages and ongoing hybridization in two declining shad species, highlighting the impact of historical and recent demographic processes on their genetic structure.

Long distance migration is a major factor driving local adaptation at continental scale in Coho Salmon

This study identifies long-distance migration as a key driver of local adaptation in Coho Salmon across North America, revealing genetic associations with migration and altitude.

Balancing selection at a wing pattern locus is associated with major shifts in genome-wide patterns of diversity and gene flow in a butterfly

The paper examines how balancing selection at a wing pattern locus in butterflies affects genome-wide diversity and gene flow, finding higher diversity and lower geographic structure in polymorphic populations.

Demographic history shaped geographical patterns of deleterious mutation load in a broadly distributed Pacific Salmon

The paper reconstructs the demographic history of Coho salmon to show how past population dynamics shaped regional differences in deleterious mutation load.

Demographic history and genomics of local adaptation in blue tit populations

The paper examines demographic history and local adaptation in blue tit populations, finding weak differentiation between habitat types and stronger differentiation between insular and mainland populations.

Riverscape genetics in brook lamprey: genetic diversity is less influenced by river fragmentation than by gene flow with the anadromous ecotype

This study examines how river fragmentation affects genetic diversity in brook lamprey, finding that gene flow with an anadromous ecotype has a greater impact than barriers.

Combining population genomics and forward simulations to investigate stocking impacts: A case study of Muskellunge (Esox masquinongy) from the St. Lawrence River basin

This study uses genomic data and simulations to assess the genetic impacts of fish stocking on Muskellunge populations in the St. Lawrence River basin, finding weak effects in large rivers but stronger effects in smaller stocked populations.

Massive postglacial gene flow between European white oaks uncovered genes underlying species barriers

The paper identifies genomic regions and genes underlying reproductive barriers in European white oaks, revealing postglacial gene flow and ecological adaptations.

Genomics and telemetry suggest a role for migration harshness in determining overwintering habitat choice, but not gene flow, in anadromous Arctic Char

This study combines genomics and telemetry to show that Arctic Char choose overwintering habitats based on migration difficulty, not gene flow, and identifies genes related to muscle and cardiac function under selection.

Reconstructing The Demographic History Of Atlantic Salmon (Salmo salar) Across Its Distribution Range Using Approximate Bayesian Computations

This study uses approximate Bayesian computations to reconstruct the demographic history of Atlantic Salmon, revealing gene flow and selection effects across its range.
