Temperature effects on intra- and extracellular acid-base status in the American locust, Schistocerca nitens

This study examined the effect of temperature on hemolymph and intracellular acid-base status in the locust, Schistocerca nitens . Hemolymph pH decreased with temperature by 0.017 pH units multiplied by degree C super(-1) above 25 degree C, but was stable at lower temperatures. Average intracellular...

Description
Summary:This study examined the effect of temperature on hemolymph and intracellular acid-base status in the locust, Schistocerca nitens . Hemolymph pH decreased with temperature by 0.017 pH units multiplied by degree C super(-1) above 25 degree C, but was stable at lower temperatures. Average intracellular pH decreased by approximately 0.018 pH units multiplied by degree C super(-1), in accordance with predictions for preservation of relative alkalinity and protein charge state.
