Natural CO₂ seeps reveal adaptive potential to ocean acidification in fish.

ABSTRACT: Volcanic CO₂ seeps are natural laboratories that can provide insights into the adaptation of species to ocean acidification. While many species are challenged by reduced-pH levels, some species benefit from the altered environment and thrive. Here, we explore the molecular mechanisms of adaptation to ocean acidification in a population of a temperate fish species that experiences increased population sizes under elevated CO₂. Fish from CO₂ seeps exhibited an overall increased gene expression in gonad tissue compared with those from ambient CO₂ sites. Up-regulated genes at CO₂ seeps are possible targets of adaptive selection as they can directly influence the physiological performance of fishes exposed to ocean acidification. Most of th
