Ionic Regulation in Animals A Tribute to Professor W.T.W.Potts [Paperback]

This book draws together the most relevant and recent advances in the area of ionic transport in animals. In particular, it describes the role of modern cell and molecular biology research techniques in this rapidly advancing field. These techniques have led to important advances in our knowledge of cellular mechanisms of ion transporting epithelia, the role and expression of osmoregulatory hormones and a new understanding of whole body salt and water balance.1 The Ecophysiology of Osmoregulation in Crustacea.- 1.1 Introduction.- 1.2 Steady-state strategies.- 1.3 The development of osmoregulatory capacity.- 1.4 Brood pouches and osmoregulation.- 1.5 Environmental effects on crustacean osmoregulation.- 1.5.1 Effects of external [ion] or salinity.- 1.5.2 Effects of water pH change on osmoregulation.- 1.5.3 Effects of ammonia and nitrate.- 1.5.4 Other factors.- 1.6 Intraspecific difference in osmoregulation.- 1.7 Conclusions.- References.- 2 Ambient ions and the voltage across crayfish gills.- 2.1 Introduction.- 2.2 Experimental Results.- 2.2.1 Tap water medium and Amiloride.- 2.2.2 The effect of Ca2+.- 2.2.3 The effect of Na+.- 2.2.4 The effect of Cl-.- 2.3 Discussion.- 2.3.1 The TEP and ambient ion.- 2.3.2 Implication for ion transport systems.- References.- 3 Regulating the micro-environment of ion transporting epithelia: A comparative approach.- 3.1 Introduction.- 3.2 Water movements across epithelia.- 3.3 Secretion by goblet cells.- 3.4 Exocytosis, swelling and dispersal of mucus.- References.- 4 Osmotic and Ionic Osmoregulation in Cyclostomes.- 4.1 Introduction.- 4.2 Hagfish.- 4.2.1 Volume Regulation.- 4.3 Lamprey.- 4.3.1 Osmoregulation in lampreys.- 4.3.2 The lamprey kidney.- 4.3.3 Materials and Methods.- 4.3.4 Freshwater Osmoregulation.- 4.3.5 Marine Osmoregulation.- 4.3.6 Renal function.- 4.3.7 Drinking.- 4.3.8 Loss of Marine Osmoregulatory Ability after Freshwater Entry.- 4.4 Control Mechanisms.- 4.5 Conclusions.- 4.6 Acknowledgements.- References.- 5 Ion andlc*
