Sexual maturation timing is a life‐history trait central to the balance between mortality and
reproduction. Maturation may be triggered when an underlying compound trait, called …

A major goal in biology is to understand how evolution shapes variation in individual life
histories. Genome-wide association studies have been successful in uncovering genome …

Understanding the mechanisms by which populations adapt to their environments is a
fundamental aim in biology. However, it remains challenging to identify the genetic basis of …

Wild and domesticated Atlantic salmon males display large variation for sea age at sexual
maturation, which varies between 1–5 years. Previous studies have uncovered a genetic …

Efforts to understand the genetic underpinnings of phenotypic variation are becoming more
and more frequent in molecular ecology. Such efforts often lead to the identification of …

In Atlantic salmon, age at maturation is a life history trait governed by a sex‐specific trade‐off
between reproductive success and survival. Following environmental changes across large …

Co‐inheritance in life‐history traits may result in unpredictable evolutionary trajectories if not
accounted for in life‐history models. Iteroparity (the reproductive strategy of reproducing …

Age at maturity is a key life‐history trait of most organisms. In anadromous salmonid fishes
such as Atlantic Salmon (Salmo salar), age at sexual maturity is associated with sea age, the …

Age at maturity is a key life history trait involving a trade-off between survival risk and
reproductive investment, and is an important factor for population structures. In ectotherms, a …

Wild Atlantic salmon populations show heritable variation in the proportion of fish that
mature early, as grilse, after one winter at sea. Grilse are undesirable in aquaculture, and in …
