Antarctic Fish Physiology
The waters surrounding the southernmost continent have been relatively stable for millions of years, which may enhance the vulnerability of its fishes to novel rates of warming and ocean acidification. This past field season, we studied the capacity of juvenile Trematomous Bernacchii to acclimate to projected climate change conditions by assessing physiological, biochemical, and behavioral metrics. Juveniles were collected from the wild and exposed to a long-term acclimation of projected ocean warming and ocean acidification simultaneously. Particularly we are interested in understanding the effect of multiple stressors and how fish responses change with longer acclimations.
