... Ltd 2018 http://www.biologists.com/user-licence-1-1/ Summary: Low water pH limits extracellular pH compensation in a CO 2 -tolerant fish. This may increase selection for a more robust CO 2 defence strategy where intracellular pH is preferentially regulated. Acid–base Hypercarbia...

...Michael Brannen; Kathleen M. Gilmour ABSTRACT Rainbow trout ( Oncorhynchus mykiss ) exposed to acid–base challenges activate branchial mechanisms for the excretion of acid–base equivalents. Current models of branchial acid–base excretion in freshwater rainbow trout propose two main ionocyte types...

... of the Cl–HCO 3 exchanger AE1( Groves and Tanner, 1992 ). The inclusion of the AID and IRBIT-binding domain in certain splice variants of NCBTs allows for upregulation of HCO 3 – transport in response to physiological cues. IRBIT-mediated stimulation of other acid–base transporters such as NHE3( He...

...D. J. Randall; T. K. N. Tsui SUMMARY The gills are the major site of acid–base regulation in most fish. Acid–base transfer across fish gills is dominated by carbon dioxide and ammonia excretion, especially the former. Bicarbonate buffering in the blood is less than that found in mammals; regulation...

... ). The saturation of the Hc in venous haemolymph ranged from 45% in crabs at rest to 28% in the 90% RH group, which was significantly lower than that of both rested crabs and those exercised at 40% RH ( Table 1 ). Table 1. Haemolymph respiratory and acid–base status of laboratory acclimated Discoplax...

.... A low urine pH is needed to achieve high rates of excretion of NH 4 + . Hence the price to pay to defend acid–base balance would be to accept a risk of precipitation of uric acid in the terminal nephron. This led us to reconsider the traditional view of the physiology of the excretion of NH 4...

... towards submerged levels. Possibilities for the fate of lactate are discussed. Re-analysis of haemolymph acid-base data for crayfish exposed to air (Taylor & Wheatly, 1981) revealed discrepancies between observed and expected base excess. Initially these may arise from exchanges of H + or HCO 3...

... pressure. Measurements of both conventional acid-base parameters (pH, P CO 2 . total CO 2 ) and ‘strong’ ion concentrations (Na + , K + , Mg 2+ , Ca 2+ and Cl − ) were made at various times during each treatment. Intracellular [Na + ], [K + ] and [Cl − ] were determined for red and white muscle in control...

The dominant acid-base response was a progressive metabolic alkalosis accompanied by a partially compensating rise in Pa CO CO2 . Alkalosis was probably caused by blockage of the normal aquatic excretion of base produced by the metabolism...
