Brown trout Salmo trutta is endemic to Europe, western Asia and north‐western Africa; it is a
prominent member of freshwater and coastal marine fish faunas. The species shows two …

Over the past decades, Atlantic salmon (Salmo salar, Salmonidae) has emerged as a model
system for sexual maturation research, owing to the high diversity of life history strategies …

Declines in animal body sizes are widely reported and likely impact ecological interactions
and ecosystem services. For harvested species subject to multiple stressors, limited …

Males and females often differ in their fitness optima for shared traits that have a shared
genetic basis, leading to sexual conflict. Morphologically differentiated sex chromosomes …

Understanding the drivers of evolution is a fundamental aim in biology. However, identifying
the evolutionary impacts of human activities is challenging because of a lack of temporal …

Arctic regions support a wide variety of freshwater ecosystems. These naturally oligotrophic
and cold‐water streams, rivers, ponds and lakes are currently being impacted by a diverse …

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 …

Background Understanding genetic architecture is essential for determining how traits will
change in response to evolutionary processes such as selection, genetic drift and/or gene …

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 …

Understanding the genetic basis of repeated evolution of the same phenotype across taxa is
a fundamental aim in evolutionary biology and has applications in conservation and …
