Abstract
Cambarus robustus is more tolerant of low environmental pH than Orconectes rusticus and this tolerance reflects a difference in ion regulation physiology. Chronic exposure (96 h) of the acid-tolerant C. robustus to pH 3.8 soft water did not significantly change haemolymph [Na+] or [Ca2+] of the adults or total body [Na+] of the juveniles relative to the control (pH 6.5). In contrast, the intolerant O. rusticus showed a significant decrease in [Na+] and increase in [Ca2+] in adult haemolymph (Wood and Rogano. 1986. Can. J. Fish. Aquat. Sci. 43: 1017–1026) and an increase in total body [Na+] of stage III juveniles following acute exposure to pH 3.8 compared with the pH 6.5 control.This publication has 3 references indexed in Scilit:
