... magnitude of thermal plasticity may be masked or modified under food restriction. This reduction in RMR was associated with atrophy and decreases in in vivo protein synthesis rates, primarily in non-essential tissues. Remarkably, food deprivation had no effect on maximum oxygen uptake rates and thus aerobic...

... for swimming (CTS max ) while exercising aerobically until fatigue and the critical thermal maximum (CT max ) under static conditions until loss of equilibrium (LOE). In the CTS max protocol, warming caused a profound increase in the rate of oxygen uptake ( Ṁ O 2 ), culminating in a gait transition from steady...

We measured oxygen uptake rates to verify whether alterations in the partitioning between EWL Skin and EWL Resp were...

Although influential theory claims that metabolic scaling is constrained by internal body design, our study builds on previous work to show...

... 2016 Highlighted Article: Longitudinal observations of respiration times and underwater activity level indicate that consideration of respiration timing, in addition to respiration rate, is critical for estimating metabolic rates of free-ranging cetaceans. Metabolic rate Oxygen uptake...

... in bar-headed geese raised at high altitude. Thus, bar-headed geese reared at high altitude exhibited a reduced oxygen demand at rest and a modest but significant increase in oxygen uptake and delivery during progressive hypoxia compared with bar-headed geese reared at low altitude. Each goose...

... of oxygen uptake from both water and air ( Farmer and Jackson, 1998 ). The specific objectives of this study were to examine: (1) whether air breathing is obligatory in order for G. carapo to achieve maximum aerobic scope and swimming performance in aquatic normoxia and (2) whether air breathing allows...

Here I show how the temperature dependence of aerobic scope (the difference between maximum and minimum rates of oxygen uptake) is a useful tool to examine the fundamental temperature niches of salmonids...

... uptake is constant, as observed under resting conditions. However, when the oxygen uptake rate of the animal changes to a new steady-state level, there is a delay in the establishment of a new steady-state P O 2 of the water exiting the respirometer. The approach to a new steady-state level...

... of no quantitative importance. Calculations derived by three independent methods (each with N =3) revealed that the oxygen uptake of sandeel buried for 6–7 h was 40–50% of previous estimates on resting respirometry of non-buried fish, indicating lower O 2 requirements during burial on a diurnal timescale. Buried...
