Inhaltsangabe
Foreword Preface Acknowledgements1. INTRODUCTION Introducing crocodylians The living species of crocodylians The growth of scientific knowledge about crocodylians Body size and age2. THE CROCODYLIAN FAMILY TREE The modern crocodylians and their relationships Extinct Crocodylia and other crocodile-like reptiles; crocs in 'deep time' Summary3. CROCODYLIANS CLOSER UP The external features of crocodylians Skull and musculoskeletal system4. LOCOMOTION, BUOYANCY, AND TRAVEL Crocodylians on land Crocodylians in the water Buoyancy Stomach stones (gastroliths) Capacity for long distance travel5. SENSORY SKILLS AND BRAIN Vision Hearing, movement and balance Brain and cranial nerves Olfaction and gustation (chemosensation) Sense organs of the skin Cognitive capacities and learning6. FEEDING, DIGESTION, AND NUTRITION What do crocodylians eat? Prey capture and handling Digestion Nutrition7. ENERGY SUPPLY AND DELIVERY The metabolic engines: crocodylian biochemistry and metabolism Whole body metabolism (anaerobic and aerobic) The respiratory system The circulatory system8. THE WORLD'S MOST EXTRAORDINARY HEART A tour of the crocodylian heart Non-shunting and shunting patterns of blood flow What is the significance of pulmonary by-pass shunting in crocodylians?9. DIVING AND SUBMERGENCE BEHAVIOUR AND PHYSIOLOGY When? Why? How deep? How, and how for so long? Diving behaviour of crocodylians in the wild Physiological support for crocodylian diving What are the longest submergences by crocodylians that can be supported aerobically?10. THERMAL RELATIONS Introduction: crocodylians are not like other reptiles Daily and seasonal patterns of body temperature Behaviours that modify body temperature Physiological mechanisms of thermoregulation Thermal acclimatization Crocodylians may have endothermic ancestry Could even the basal archosaurs have been endothermic?11. SALT AND WATER BALANCE Salt and water balance in Crocodylus porosus: an introduction to crocodylian osmoregulation Salt and water balance in other crocodylians Living out of water, 'aestivation' Salt glands and implications for crocodylian evolutionary history12. REPRODUCTION Introduction: they're more like birds Oviducts, ovulation, fertilisation and the gravid stage13. POPULATIONS AND POPULATION ECOLOGY Populations (and species) Population dynamics: changes through time Case Histories14. CONSERVATION, COMMERCIALISATION, AND CONFLICT Introduction Historical perspective The future for crocodylians?INDEX
