This easy-to-read handbook provides a comprehensive review of the current knowledge on lichens. The structure of lichens and their dual nature is explained, as well as the physiology of interaction of the symbionts. The way lichens reproduce and their ecology is included, with methods for cultivating them and their isolated symbionts. Extremely useful as a text of lichenology, this handbook will benefit students of lichenology and allied fields, those interested in symbiotic associations and ecology, and teachers of biology, botany, and ecology courses.

First published in 1988 and now known as a classic. In this book Stephen Fry describes, in bench-top detail, techniques for the study of primary cell walls in higher plants. Deepening interest in the chelistry and metabolism of cell walls reflects the breadth of their significance in biology. Walls play crutial roles in morphogenesis, growth, disease-resistance, recognition, signalling, digestibility, nutrition and decay. Scientists interested in questions concerning these processes need to know about methods of cell wall analysis. This book was written with these people in mind. There are 11 chapters as follows: 1. Introduction to the growing plant cell wall 2. Radioactive labelling of cell walls 3. Wall polymers: extraction and fractionation 4. Wall polymers: chemical characterisation 5. Wall biosyntesis 6. Wall enzymes 7. Wall architecture 8. Wall turnover and sloughing 9. Biologically-active wall oligosaccharides 10. Wall tightening and loosening: growth 11. Wall degradation "Stephen Fry has written an invaluable book on the analytical techniques available in this important research field. This is an excellent book for the typical modern biologist." J. Experimental Biology "This book will be of considerable value to anyone engaged in the analysis of plant cell walls." Ann. Botany "For those who intend to do any practical cell wall analysis this book will be an invaluable laboratory manual." Plant Pathology "As a practical guide to wall analysis this book will be a most valuable tool." Times Higher Education Supplement

The Negev , first published over a decade ago, told the story of some twenty years of study of southern Israel's desert. It synthesized the findings of botanists, geologists, soil scientists, agronomists, archaeologists, historians, and engineers and told how the applications of their work produced an agricultural surplus in this forbiddingly dry, hot region. , Now Michael Evenari has amplified the book with data from another decade of work. He describes the efforts at a new farm at Wadi Mashash, extends the weather data another ten years, presents further work on the adaptations of plants and animals to desert conditions, and takes a much deeper look at the historical precedents for the method of runoff agriculture, which has made the desert bloom.
