Impact of Short- and Long-Term Exposure to Elevated Seawater Pco on Metabolic Rate and Hypoxia Tolerance in .

AbstractMuch of the CO released by human activity into the atmosphere is dissolving into the oceans, making them more acidic. In this study we provide the first data on the short- and long-term impacts of ocean acidification on octopuses. We measured routine metabolic rate (RMR) of at elevated CO pressure (Pco) with no prior acclimation and 1 or 5 wk of acclimation and critical oxygen pressure (P) after 5 wk of acclimation.
