Abstract

(1) The range of temperature exposure of endotherms is narrow compared to ectotherms that can experience daily and seasonal temperature fluxes. (2) Comparison of the blood viscosity of amphibians (bullfrog, Woodhouse's toad, and marine toad) and mammals (horse, dog, and rat) at 3°C and 38°C was undertaken to determine if the effect of temperature on blood viscosity was diminished in amphibians relative to mammals. (3) Mammals did not consistently show greater changes in blood viscosity, plasma viscosity, or relative viscosity with decreasing temperatures relative to the amphibians in this study. (4) These data do not support our hypothesis that blood viscosity of amphibians is less affected by temperature than mammalian blood. © 2002 Elsevier Science Ltd. All rights reserved.
