Relationship between RMR and ROUTINE respiration obtained in intact blood cells from Japanese quail (Coturnix japonica). Half of the birds were acclimated at 10°C (blue dots) while the other half was acclimated at 30°C (red dots) for 11 weeks. RMR was measured at 30°C, which is thermoneutral in Japanese quail, and blood respiration was measured at 41°C. A Pearson correlation test on pooled data revealed no significant association between RMR and ROUTINE. Nor was this relationship significant within groups (cold birds: R=0.255, P=0.306; warm birds: R=−0.250, P=0.275).
