Impact of short- and long-term exposure to elevated seawater pCO2 on metabolic rate and hypoxia tolerance in Octopus rubescens
Much of the CO 2 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) and critical oxygen pressur...
