Correlations between basal metabolic rate (BMR), state-4 respiration, and cytochrome c oxidase in the liver, kidneys, heart, and pectoral muscle of Red-billed Leiothrixs (Leiothrix lutea) acclimated to different temperatures for 4 weeks. Correlation analyses demonstrated that liver state-4 respiration (a), kidney state-4 respiration (c), kidney cytochrome c oxidase (COX) activity (d), heart state-4 respiration (e), muscle state-4 respiration (g), and muscle COX activity (h) were significantly positively correlated with BMR, but liver (b) and kidney (f) COX activities were not significantly correlated with BMR
