Scarcity of water has brought about a number of structural, behavioural, physiological and ecological adaptations in amphibians inhabiting seasonally xeric habitats. This book describes structural and functional adaptations of key organs such as skin, kidneys, bladder, lungs and ovaries. Behavioural responses to high temperatures mainly involve thermoregulation and the selection of optimal temperatures and humidity. Special emphasis is placed on physiological adaptations: water, electrolyte, nitrogen, and thermal balance and their endocrine control are treated in detail. Development and metamorphosis, larval competition for food resources, and reproductive strategies are only a few of the exciting topics in the chapter on ecological aspects.
