Upwelling-level acidification and pH/pCO₂ variability moderate effects of ocean acidification on brain gene expression in the temperate surfperch, Embiotoca jacksoni.

ABSTRACT: Acidification-induced changes in neurological function have been documented in several tropical marine fishes. Here, we investigate whether similar patterns of neurological impacts are observed in a temperate Pacific fish that naturally experiences regular and often large shifts in environmental pH/pCO₂ . In two laboratory experiments, we tested the effect of acidification, as well as pH/pCO₂ variability, on gene expression in the brain tissue of a common temperate kelp forest/estuarine fish, Embiotoca jacksoni. Experiment 1 employed static pH treatments (target pH = 7.85/7.30), while Experiment 2 incorporated two variable treatments that oscillated around corresponding static treatments with the same mean (target pH = 7.85/7.70) in an eight-day cycle (amplitude ± 0.1
