Mitochondrial plasticity and environmental change in Antarctic, Austral and temperate fish
The efficiency and adaptive plasticity of mitochondrial metabolism is one of the key factors shaping organismal tolerance towards environmental change.We thus investigated the adaptive capacities of mitochondrial metabolism in Antarctic & Austral notothenioids (Nothothenia rossii, N. coriiceps &...
