Groups | Temp. (°C) | Ṁ_{O2} (mg kg^{−1} h^{−1}) | [O_{2}]_{crit} (mg 1^{−1}) | Ṁ_{O2}:[O_{2}]_{crit} |
---|---|---|---|---|
A | 10 | 38.9±4.5^{b,c,d} | 1.43±0.13^{b,c,d} | 27.4±2.1^{b,c,d} |
B | 15 | 88.2±7.9^{a,d} | 2.45±0.18^{a,c,d} | 36.0±2.0^{a,d} |
C | 20 | 122.7±12.2^{a,d} | 3.55±0.29^{a,b} | 34.5±1.1^{a,d} |
D | 25 | 209.5±15.1^{a,b,c} | 4.02±0.27^{a,b} | 52.1±1.6^{a,b,c} |
Significant temperature-dependent changes in the mean values for rate of oxygen consumption (Ṁ_{O2}), critical oxygen tension ([O_{2}]_{crit}) and the ratio between the two at the different temperatures, are indicated by an ANOVA (P<0.0001). The superscripted letters (a,b,c,d) denote significant differences (P<0.05) between groups (A,B,C,D) within a variable. An increase of Ṁ_{O2}:[O_{2}]_{crit} ratio indicates an improvement of the capacity for oxygen uptake.
