ORIGINAL ARTICLE: Propensity of marine reserves to reduce the evolutionary effects of fishing in a migratory species
Abstract Evolutionary effects of fishing can have unwanted consequences diminishing a fishery’s value and sustainability. Reserves, or no‐take areas, have been proposed as a management tool for reducing fisheries‐induced selection, but their effectiveness for migratory species has remained unexplore...
