This textbook provides a comprehensive overview on the diverse strategies invertebrate animals
have developed for nitrogen excretion and maintenance of acid-base balance and summarizes the
most recent findings in the field obtained by state-of-the-art methodology. A broad range of
terrestrial freshwater and marine invertebrate groups are covered including crustaceans
cephalopods insects and worms. In addition the impact of current and future changes in ocean
acidification on marine invertebrates due to anthropogenic CO2 release will be analyzed. The
book addresses graduate students and young researchers interested in general animal physiology
comparative physiology and marine aquatic animal physiology. Also it is an essential source for
researchers dealing with the effects of increasing pCO2 levels on aquatic animals of which the
vast majority are indeed invertebrates. All chapters are peer-reviewed.
