Regulation of gene expression is associated with tolerance of the Arctic copepod Calanus glacialis to CO₂-acidified sea water.

ABSTRACT: Ocean acidification is the increase in seawater pCO ₂ due to the uptake of atmospheric anthropogenic CO ₂, with the largest changes predicted to occur in the Arctic seas. For some marine organisms, this change in pCO ₂, and associated decrease in pH, represents a climate change-related stressor. In this study, we investigated the gene expression patterns of nauplii of the Arctic copepod Calanus glacialis cultured at low pH levels. We have previously shown that organismal-level performance (development, growth, respiration) of C. glacialis nauplii is unaffected by low pH. Here, we investigated the molecular-level response to lowered pH in order to elucidate the physiological processes involved in this tolerance. Nauplii from wild-
