Exploration behavior of Atlantic salmon parr in small tributary streams of a large subarctic river is associated with a genomic region strongly affecting age at maturity variation. Check out our new paper --> besjournals.onlinelibrary.wiley.com/doi/10.1111/...

Early life exploration behaviour and life‐history loci are colocalized in an adaptive genomic hotspot in Atlantic salmon

The genetic architecture of phenotypic correlations offers insights into how natural selection operates in the wild. Two functional phenotypes in Atlantic salmon, early life exploration and age-at-ma...

Coho are typically thought to rear in their natal habitat for a year before migrating to sea. We found that many fish (44%) leave their natal habitat early and spend several months rearing in the lower portion of the creek before emigrating. (3/8)
