Maximum proton leak capacities (state IV+) as a putative fraction of total mitochondrial state III respiration (complex I and II, liver) in N. rossii and L. squamifrons.

Values are given as means ± SEM over all assay temperatures (0, 6, 12°C) of control/acclimated N. rossii (control: 1°C, 0.04 kPa CO2, n = 9; warm normocapnic: 7°C, 0.04 kPa CO2, n = 5; cold hypercapnic: 1°C, 0.2 kPa CO2, n = 10; warm hypercapnic 7°C, 0.2 kPa CO2, n = 10) and L. squamifrons (control: 2°C, 0.04 kPa CO2, n = 7; warm normocapnic 9°C, 0.04 kPa CO2, n = 5).#indicates a significant (ANOVA, PN. rossii control group.aindicates a significant (ANOVA, PL. squamifrons control.
