...Bronwyn A. Ellis; Stephen Morris ABSTRACT Freshwater habitats throughout the world are becoming increasingly threatened by the likelihood of acidification, but little consideration has been given to the importance of severe alkalization. Acute and chronic fluctuations in haemolymph acid–base status...

... and oxygen consumption rate, haemolymph oxygen transport and haemolymph glucose and lactate concentrations were determined. The effect of reducing environmental [Ca 2+ ] in acid water from 500 to 50 μ mol l −1 was also examined. In acid water (500 μ mol l −1 Ca 2+ ), oxygen uptake by Cherax was reduced by 79...

...Walter F. Boron; Steven J. Waisbren; Irvin M. Modlin; John P. Geibel ABSTRACT Although many factors can influence intracellular pH (pHi), some of the most important are those that involve the movement of acids and bases across the cell membrane. We will discuss recent results concerning barriers...
