Summary: | IntroductionOngoing ocean warming and acidification increasingly affect marine ecosystems, in particular around the Antarctic Peninsula. Yet little is known about the capability of Antarctic notothenioid fish to cope with rising temperature in acidifying seawater. While the whole animal level is expected to be more sensitive towards hypercapnia and temperature, the basis of thermal tolerance is set at the cellular level, with a putative key role for mitochondria. This study therefore investigates the physiological responses of the Antarctic Notothenia rossii after long-term acclimation to increased temperatures (7°C) and elevated PCO2 (0.2 kPa CO2) at different levels of physiological organisation.ResultsFor an integrated picture, we analysed the acclimation capacities of N. rossii by measuring routine metabolic rate (RMR), mitochondrial capacities (state III respiration) as well as intra- and extracellular acid-base status during acute thermal challenges and after long-term acclimation to changing ... : Supplement to: Strobel, Anneli; Bennecke, Swaantje; Leo, Elettra; Mintenbeck, Katja; Pörtner, Hans-Otto; Mark, Felix Christopher (2012): Metabolic shifts in the Antarctic fish Notothenia rossii in response to rising temperature and PCO2.
