Responses of population structure and genomic diversity to climate change and fishing pressure in a pelagic fish

Abstract

Anthropogenic climate change drives several major changes in marine ecosystems, including increasing sea temperatures, changes in dissolved oxygen concentration, and decreases in ocean pH (Bahri et al., 2018;Mora, Wei, et al., 2013;Worm & Lotze, 2021). The contemporary and future impacts of these changes on marine species are not always well understood, but modeled simulations can be used to better understand the impact of climatic changes on adaptation and genomic vulnerability (Cheung et al., 2009;Nielsen et al., 2021), and for predicting the spatial distributions of species under projected future conditions (
