Genotype-specific variation in seasonal body condition at a large-effect maturation locus
Organisms use resource allocation strategies to survive seasonal environmental changes and life-history stage transitions. Earlier studies found a transcription cofactor, v gll3, associating with maturation timing that inhibits adipogenesis in mice and affects body condition in juvenile salmon. Owin...

Organisms use resource allocation strategies to survive seasonal environmental changes and life-history stage transitions. Earlier studies found a transcription cofactor, v gll3, associating with maturation timing that inhibits adipogenesis in mice and affects body condition in juvenile salmon. Owing to a lack of temporal studies examining seasonality effects on phenotypes such as vgll3 genotype, body condition, maturation and different life stages, we investigated the influence of different larval and juvenile temperatures, vgll3 genotype and interactions with body condition and maturation rate. We reared Atlantic salmon for 2 years in four larval–juvenile phase temperature groups until the occurrence of mature males.
