Selective breeding in aquaculture is necessary to establish food security and meet demand for sustainably produced protein. An informed selective breeding program requires understanding how population structure, environmental adaptation, and human activities shape natural genetic variation in wild conspecifics. Unfortunately, wild variation remains poorly characterised for many commercially important aquaculture species. Here,...

Predicting how populations will respond to climate change is an urgent priority in evolutionary and conservation biology. Genetic and environmental influences have long been known to impact responses to shifting climates, giving rise to the development of genomic offset methods that attempt to predict the degree of maladaptation following environmental change. Although these methods have the potential to improve our understand...
