THERMAL AND CO2-EFFECTS ON ANTARCTIC FISH (NOTOTHENIA ROSSII): DOES MITOCHONDRIAL PLASTICITY LIMIT METABOLIC PERFORMANCE?
Temperature is a key factor shaping performance of ectothermal organisms. Furthermore, their thermal tolerance windows may be narrowed by the ongoing process of ocean acidification. Consequently, these organisms may become even more sensitive to warming. As mitochondrial metabolism is one of the mos...
