 in a collaboration with Amelie Crespel and Shaun Killen, we brought some genomics to an applied evolutionary question - is there evolutionary response to fisheries harvesting? We suspected that forces like size-selective harvest can have impact but what about environmental or demographic context? Open access paper here ! Crespel A, Schneider K, Miller T, Rácz A, Jacobs A, Lindström J, Elmer KR, Killen SS (2021) Genomic basis of fishing-associated selection varies with population density. Proc Natl Acad Sci U S A, 118, e2020833118. Significance: Fisheries-associated selection is recognized as one of the strongest potential human drivers of contemporary evolution in natural populations. The results of this study show that while simulated commercial fishing techniques consistently remove fish with traits associated with growth, metabolism, and social behavior, the specific genes under fishing selection differ depending on the density of the targeted population. This finding sug...
