Uiters belangrike narratief oor skooltaalvoorkeur het hom tussen 2006 en 2010 in Suid-Afrika afgespeel. Hierdie gebeurtenisse het diep in die Suid-Afrikaanse onderwys- en taalwêreld ingesny, en ook in die buiteland belangstelling gelok. Die koerante het volledig daaroor berig: oor die hofsake, die skoolhoofde, die skole, ouers en die leerders. Maar hoe gemaak as onderwyskundiges, sosiolinguiste, taalbeplanners, taalhistorici en vaklui van aansluitende dissiplines later die punte van hulle vingers op die besonderhede van daardie gebeurtenisse wil lê? |

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. . |
