Indigenous microbiota play a critical role in the lives of their vertebrate hosts. In human and
mouse models it is increasingly clear that innate and adaptive immunity develop in close …

Emerging diseases are impacting animals under high‐density culture, yet few studies
assess their importance to wild populations. Microparasites selected for enhanced virulence …

Evolutionary ecologists and population biologists have recently considered that ecological
and evolutionary changes are intimately linked and can occur on the same time-scale …

What is the extent and scale of local adaptation (LA)? How quickly does LA arise? And what
is its underlying molecular basis? Our review and meta-analysis on salmonid fishes …

This brief review focuses on health and biological function as cornerstones of fish welfare.
From the function-based point of view, good welfare is reflected in the ability of the animal to …

The commensal microbiota of fish skin is suspected to provide a protection against
opportunist infections. The skin of fish harbors a complex and diverse microbiota that closely …

The major histocompatibility complex (MHC) forms an integral component of the vertebrate
immune response and, due to strong selection pressures, is one of the most polymorphic …

Infectious diseases are economically detrimental to aquaculture, and with continued
expansion and intensification of aquaculture, the importance of managing infectious …

A growing number of studies are examining the factors driving historical and contemporary
evolution in wild populations. By combining surveys of genomic variation with a …

Driven by co‐evolution with pathogens, host immunity continuously adapts to optimize
defence against pathogens within a given environment. Recent advances in genetics …
