... coronary O 2 delivery affects tolerance to environmental extremes such as warming and hypoxia. Hypoxia reduces arterial oxygenation, while warming increases overall tissue O 2 demand. Thus, as both stressors are associated with reduced venous O 2 supply to the heart, we hypothesised that coronary flow...

.... Concomitantly, they exhibit elevated cardiac output and a doubling of gastrointestinal blood flow to provide additional O 2 to the gut and increase convective flux of absorbed ions and water. Yet, it is unknown how warming waters, which elevate tissue O 2 demand and the rate of diffusion of ions and water...

... and myoglobin, lack regulatory cardiovascular flexibility during acute warming and activity. The experimental protocols were designed to optimize the surgical protocol and minimize stress. First, minimally invasive heart rate ( f H ) measurements were made during a thermal ramp until cardiac failure in C...

... a poor capacity to resist warming. Here we show that their ability to acclimate their physiology to elevated temperatures is poor compared with species from temperate latitudes, and similar to those from the tropics. Those species that have been demonstrated to acclimate take a very long time to do so...
