Fish biology has been developed for more than 100 years, but some important
breakthroughs have been made in the last decade. Early studies commonly concentrated on …

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 …

The unprecedented rate of extinction calls for efficient use of genetics to help conserve
biodiversity. Several recent genomic and simulation-based studies have argued that the …

Differentiation between ecotypes is usually presumed to be complex and polygenic.
Seasonal patterns of life history in salmon are used to categorize them into ecotypes, which …

The repeated adaptation of oceanic threespine sticklebacks to fresh water has made it a
premier organism to study parallel evolution. These small fish have multiple distinct …

Supergenes are genomic regions containing sets of tightly linked loci that control multi-trait
phenotypic polymorphisms under balancing selection. Recent advances in genomics have …

The increasing feasibility of assembling large genomic datasets for non-model species
presents both opportunities and challenges for applied conservation and management. A …

The genetic architecture of a phenotype can have considerable effects on the evolution of a
trait or species. Characterizing genetic architecture provides insight into the complexity of a …

Structural variants (SVs) are a major source of genetic and phenotypic variation, but remain
challenging to accurately type and are hence poorly characterized in most species. We …

A paradox in evolutionary biology is how supergenes can maintain high fitness despite
reduced effective population size, the suppression of recombination, and the expected …
