A complex mechanism translating variation of a simple genetic architecture into alternative life-histories

The paper shows that variation in the vgll3 gene affects multiple molecular pathways in Atlantic salmon, leading to different life-history strategies through complex gene interactions.

Gene co-expression patterns in Atlantic salmon adipose tissue provide a molecular link between seasonal changes, energy balance and age at maturity

The paper identifies gene co-expression patterns in Atlantic salmon adipose tissue linking seasonal changes, energy balance, and age at maturity through vgll3 genotype effects.

Genotype-specific variation in seasonal body condition at a large-effect maturation locus

This study examines how larval and juvenile incubation temperatures, along with vgll3 genotype, affect body condition and maturation rate in Atlantic salmon, finding genotype-specific seasonal variation in condition factor.

Temperature and dietary energy content influence female maturation age and egg nutritional content in Atlantic salmon

This study shows that temperature differences affect maturation age in Atlantic salmon, while diet energy content influences egg lipid content but not maturation or egg size.

Strong effects of temperature, population and age-at-maturity genotype on maturation probability for Atlantic salmon in a common garden setting

This study shows temperature, population, and vgll3 genotype strongly affect maturation probability in Atlantic salmon, with temperature effects varying by population.

Genetic stock identification reveals greater use of an oceanic feeding ground around the Faroe Islands by multi-sea winter Atlantic salmon.

The paper uses genetic stock assignment and run-reconstruction models to show that multi-sea winter Atlantic salmon use the Faroe Islands feeding ground more than previously thought, with variation among stocks and age classes.

Life-history genotype explains variation in migration activity in Atlantic salmon (Salmo salar).

The paper examines if life-history genotypes influence migration activity in Atlantic salmon, finding sex-dependent associations between vgll3 alleles and activity levels in migrants.

Genetic coupling of life-history and aerobic performance in Atlantic salmon

The paper investigates the genetic link between life-history traits and aerobic performance in Atlantic salmon, finding that early maturation genotypes are associated with higher aerobic capacity, while food availability does not modulate these genetic relationships.

Evolution in salmon life-history induced by direct and indirect effects of fishing

This study identifies direct and indirect evolutionary effects of fishing on Atlantic salmon age at maturity using genetic and phenotypic data linked to environmental and fisheries factors.

Cis-regulatory differences in isoform expression associate with life history strategy variation in Atlantic salmon

This study identifies cis-regulatory differences in vgll3 isoform expression linked to age at maturity variation in Atlantic salmon.

Large single-locus effects for maturation timing are mediated via body condition in Atlantic salmon

This study shows that vgll3 locus effects on maturation timing in Atlantic salmon are mediated through body condition, with significant heritability differences observed across environments.

Time spent in distinct life-history stages has sex-specific effects on reproductive fitness in wild Atlantic salmon

This study shows that time spent in distinct life-history stages has sex-specific effects on reproductive fitness in wild Atlantic salmon, with females benefiting more from earlier marine transition.

Bayesian arrival model for Atlantic salmon smolt counts powered by environmental covariates and expert knowledge

The paper develops a Bayesian model to estimate Atlantic salmon smolt migration timing and run size using environmental data and expert knowledge, showing 25-75% of smolts go unobserved.

Home ground advantage: selection against dispersers promotes local adaptation in wild Atlantic salmon

The paper shows that local Atlantic salmon have higher reproductive success than dispersers, promoting local adaptation without physical barriers.

Rapid sex-specific evolution of age at maturity is shaped by genetic architecture in Atlantic salmon

The paper identifies a genetic change in vgll3 associated with age at maturity in Atlantic salmon, showing sex-specific evolutionary responses and phenotypic effects over 36 years.

Genomic signatures of fine-scale local adaptation in Atlantic salmon suggest involvement of sexual maturation, energy homeostasis, behaviour, and immune defence-related genes.

This study identifies genomic regions under local selection in Atlantic salmon linked to sexual maturation, energy homeostasis, behavior, and immune defense genes.
