Table 3 Respiratory control ratio (RCR; for each assay temperature and as mean RCR over all three assay temperatures at the respective acclimation) and Q 10 of N. rossii (control: 1°C, 0.04 kPa CO 2 ; warm normocapnia: 7°C, 0.04 kPa CO 2 ; cold hypercapnia: 1°C, 0.2 kPa CO 2 ; warm hypercapnia: 7°C, 0.2 kPa CO 2 )
