Stronger Parental Than Temperature Effects on Methylation in Juvenile Brown Trout (<i>Salmo trutta</i>).

ABSTRACT: Epigenetic modifications, particularly DNA methylation, are increasingly recognized as mechanisms underlying phenotypic plasticity and potential mediators of transgenerational responses to environmental change. We investigated the persistence of early life temperature-induced DNA methylation changes and the role of parental life history in shaping methylation patterns in juvenile brown trout (Salmo trutta). Fertilized eggs from crosses of anadromous and resident trout were incubated under natural or elevated temperatures (by +3°C) until first feeding, after which all fish were reared under common conditions. Whole-genome bisulfite pooled sequencing was conducted on juveniles 10.5 months post-fertilization. We found weak and inconsistent evidence for persistent temperature-induced me
