The rich, relevant, and age appropriate content fully covers the National Curriculum and Assessment Policy Statement (CAPS), ensuring that learners stay interested throughout the year. Features: topics are structured according to CAPS which makes the course easy to use in the classroom; appropriate language levels make content accessible, build learner confidence and support independent learning and revision; a skills section at the beginning of the book introduces learners to all the scientific skills needed for life sciences; a wealth of illustrations, photographs and micrographs is provided to guide learners during practical experiments; practical activities are unpacked in a step-by-step fashion, guiding learners and teachers alike; caution boxes alert learners to any safety issues; margin features indicate content links within the grade and between the grades; an exam section with exam tips and practice papers helps learners prepare for formal assessment and exams.

This is a lightweight and portable guide, partly adapted from the popular and highly acclaimed A Field Guide to the Reptiles of East Africa by the same authors. Covering the most prominent 150 reptiles and 80 amphibians found in the region (Kenya, Tanzania, Uganda, Rwanda and Burundi), with concise text, photograph and map for each, this is a convenient and attractive pocket guide for a diverse and often conspicuous and attractive group of animals.

Inducible defenses--those often dramatic phenotypic shifts in prey activated by biological agents ranging from predators to pathogens--are widespread in the natural world. Yet research on the inducible defenses used by vertebrates, invertebrates, and plants in terrestrial, marine, and freshwater habitats has largely developed along independent lines. Ralph Tollrian and Drew Harvell seek to change that here. By bringing together leading researchers from all fields to review common themes and explore emerging ideas, this book represents the most current and comprehensive survey of knowledge about the ecology and evolution of inducible defenses.

Contributors examine organisms as different as unicellular algae and higher vertebrates, and consider defenses ranging from immune systems to protective changes in morphology, behavior, chemistry, and life history. The authors of the review chapters, case studies, and theoretical studies pinpoint unifying factors favoring the evolution of inducible defenses. Throughout, the volume emphasizes a multidisciplinary approach, integrating applied and theoretical ecology, evolution, genetics, and chemistry. In addition, Harvell and Tollrian provide an introduction and a conclusion that review the current state of knowledge in the field and identify areas for future research.

The contributors, in addition to the editors, are May Berenbaum, Arthur Zangerl, Johannes Jaremo, Juha Tuomi, Patric Nilsson, Anurag Agrawal, Richard Karban, Marcel Dicke, Ellen Van Donk, Miquel Lurling, Winfried Lampert, Simon Frost, John Gilbert, Hans-Werner Kuhlmann, Jurgen Kusch, Klaus Heckmann, Luc De Meester, Piotr Dawidowicz, Erik van Gool, Carsten Loose, Stanley Dodson, Christer Bronmark, Lars Pettersson, Anders Nilsson, Bradley Anholt, Earl Werner, Curtis Lively, Frederick Adler, Daniel Grunbaum, and Wilfried Gabriel."

Amphibians are the extant descendants of the first vertebrate class to successfully colonize terrestrial environments; hence they occupy a unique position between fish and reptiles. Amphibian skin provides essentially no resistance to evaporative water loss, and consequently daily water turnover rates are an order of magnitude greater than in other terrestrial vertebrate groups. This has led to a suite of physiological, morphological and behavioural adaptations that have allowed a successful terrestrial existence in spite of this apparently spendthrift water retention strategy. Ecological and Environmental Physiology of Amphibians provides a synthesis of current research on the comparative physiology of amphibians with a particular emphasis on water balance. It adopts a strong environmental perspective and includes a wealth of information on ecology, phylogeny and development. As with other books in the Ecological and Environmental Physiology Series, the emphasis in this book is on the unique physiological characteristics of the amphibians, although the latest experimental techniques and future research directions are also considered. This accessible text is suitable for both graduate students and researchers in the fields of amphibian comparative physiology and physiological ecology, including specialist courses in amphibian ecology. It will also be of value and use to the many professional herpetologists requiring a concise overview of the topic.
