Sponsor: AFS Genetics Section Rapid advances in genomics are providing unprecedented opportunities to improve our understanding of the amount, distribution, and functional significance of genetic variation in natural populations. Analyses on a genomic scale are now commonplace, and complete genome sequences are increasingly available for many species. These advances have facilitated discovery of loci associated with adaptation and, at times, even the causal variants shaping phenotypic variation. Our symposium, genomics of adaptation in natural populations, featured 26 presenters from the United States, Canada, France, Denmark, and Japan. Presentations covered a range of species and questions, but largely examined adaptation related to four main themes: life history variation, anthropogenic selection, thermotolerance, and fitness-related traits. Cutting-edge methods were a staple of many talks, highlighting the rapid implementation of genomics in fisheries science. Several speakers also presented on signals of selection in specific genes, demonstrating that we are also identifying the important genes and potentially the causal variants that shape phenotypic variation. With the majority of speakers being enthusiastic early career scientists, the future of fisheries genomics look bright indeed.   — Garrett McKinney, University of Washington, [email protected], and Morten Limborg Read the symposium abstracts here.
