| limited extracellular but complete intracellular acid-base regulation during short-term environmental hypercapnia in the armoured catfish, liposarcus pardalis. | environmental hypercapnia induces a respiratory acidosis that is usually compensated within 24-96 h in freshwater fish. water ionic composition has a large influence on both the rate and degree of ph recovery during hypercapnia. waters of the amazon are characteristically dilute in ions, which may have consequences for acid-base regulation during environmental hypercapnia in endemic fishes. the armoured catfish liposarcus pardalis, from the amazon, was exposed to a water p(co(2)) of 7, 14 or 42 ... | 2004 | 15326214 |
