Klappentext The maintenance of a stable acid-base status within biological tissue is a fundamental homeostatic process in all organisms! necessary to preserve the metabolic function of proteins and other macromolecules. The study of acid-base regulation has advanced enormously over recent decades due to the development of increasingly accurate and sensitive techniques for measuring acid-base variables. This volume brings together contributions from leading comparative physiologists working on factors affecting the acid-base status of the internal fluids of animals and plants. The result is a broad-ranging! authoritative and accessible review of the most recent and exciting discoveries in this area! together with a critical look at current techniques and tools.
