Both theory and empirical studies suggest that harvest-induced evolution could lead to reduced body size and earlier maturation. These evolutionary changes are unlikely to be reversed rapidly when harvesting ceases, because artificial selective pressures are often much stronger than natural selection [14]. … See more The study of harvest-induced evolution only began to attract substantial scientific attention in the 1990s, even though it had been recognized for … See more Despite the debate surrounding the paucity of rigorous investigations linking observed phenotypic trends to changes in the genetic … See more Managers should consider ‘evolutionary sustainable’ harvesting strategies to prevent the long-term negative impacts of harvest-induced evolution. Some level of harvest is usually essential because of economic reasons … See more Evolutionary changes induced by harvesting are expected to maximize individual fitness under conditions of very high adult mortality. … See more WebMay 13, 2024 · However, there is a lack of convincing examples regarding the speed and magnitude of fisheries-induced evolution, and thus, the relevant underlying molecular-level effects remain elusive. We use wild-origin zebrafish (Danio rerio) as a model for harvest-induced evolution. We experimentally demonstrate broad-scale gene expression … WebDec 6, 2013 · Across the world's oceans, size-selective harvesting by commercial fisheries has been a key driving force behind changes in phenotypic traits such as body size and … easy homemade hawaiian rolls
