Summary: | Antarctic marine ectothermal animals may be affected more than temperate species by rising ocean water temperatures due to ongoing climate change. Their specialisation on stable cold temperatures make them vulnerable to even small degrees of warming. Thus, addressing the impacts of warming on Antarctic organisms and identifying their potentially limited capacities to respond is of particular interest.The objective of the study was to determine changes in metabolite profiles related to temperature exposure and acclimation. In a long-term experiment adult fish of two Antarctic sister species Notothenia rossii and Notothenia coriiceps were acclimated to 0 °C and 5 °C for three months. Impacts and indicators of acclimation at the cellular level were determined from metabolite profiles quantified in gill tissue extracts by using nuclear magnetic resonance (NMR) spectroscopy. Furthermore, the metabolite profiles of the two con-generic species were compared.NMR spectroscopy identified over 40 metabolites that were ... : Supplement to: Rebelein, Anja; Pörtner, Hans-Otto; Bock, Christian (2018): Untargeted metabolic profiling reveals distinct patterns of thermal sensitivity in two related notothenioids.
