No International Congress of Entomology would now be complete without a symposium on insect life-cycles. The latest Congress, held at Vancouver, BC (Canada), in July 1988, was no exception, with a symposium on the genetics, evolution, and coordination of insect life cycles organized by Bill Bradshaw and Valerie Brown. The present volume arose from papers contributed by most of the speakers at the symposium, together with papers from other invited authors. In editing the book, I have been assisted greatly by the other authors, particularly Bill Bradshaw, Val Brown and Fritz Taylor. All contributors agreed to referee two other chapters, a system that worked efficiently and effectively: I thank all authors for performing this task in the face of other demands on their time. I would also like to thank Philip Corbet, John Greenslade, Bryan Clarke, and Gillian Thompson of Springer for their help.

Deserts are unique ecosystems with their own biotic and abiotic components, and are often rich in renewable natural resources, the appropriate management of which can contribute significantly to the sustainable management of desert regions for the welfare of the people. Yet while there are many books on the flora of the countries fringing the important desert countries of the Mediterranean and Red Seas, there or few books reporting on their ecophysiology and vegetation ecology. This book presents the vegetation types of the African and Asian countries of the Mediterranean and Red Sea coastal regions, and discusses the ecological threats and economic applications of these critical resources. In particular, it examines the relationships between climate and vegetation, and discusses these within the context of desertification, agro-industrial applications, ecotourism and sustainable development. The book will provide a valuable reference for researchers and graduate students involved in plant ecology, biogeography, economic botany and environmental management in the Afro-Asian Mediterranean and Red Sea coastal regions, as well as other desert regions around the world.

"Clearly Francis Gilbert is a gifted and charismatic teacher," Philip Pullman, author of 'Northern Lights'. Are you struggling to understand Robert Louis Stevenson's classic novel 'Dr Jekyll and Mr Hyde'? Or are you an English teacher wanting ready-made exercises and guidance to help you teach this difficult text? Do your students need support to understand the language properly and work independently on the book? This brilliant edition of Stevenson's novel may be the answer to your prayers. Written by an experienced teacher and best-selling author, this version is aimed at students who must analyse the text in depth or teachers wanting to deliver outstanding lessons on it. This book contains an annotated complete text, numerous essays on the novel, including detailed accounts of Robert Louis Stevenson's life, relevant contexts and discussion of vital themes and imagery. The complex vocabulary of the book is analysed throughout, and simple explanations of what is happening punctuate each chapter. Furthermore, there are academic explorations of the issues as well as comprehensive question and answer sections at the end of each chapter, including a "fill-in-the-blanks" summary to check understanding. At the end of the guide, there is advice on how to write successful essays and assignments. There are also plenty of pointers to help students develop their own personal responses, including thought-provoking thematic questions, links to the author's YouTube readings and explanations, and creative response tasks.

The book is an indispensable companion to all students of biology, but particularly those enrolled in courses concerning experimental design, data analysis, hypothesis testing, research methods, or any practical project work.

Francis Gilbert's new book tells parents the unvarnished truth about our education system, as only a teacher can. He explains that many schools are actually selective when they pretend not to be, and shows you how to get your child into the best school. He also highlights the bullying and backstabbing that can blight the lives of pupils and their parents, and shows how you can help your children to deal with it.As well as containing the compelling personal stories of many parents, the book also offers hard-earned advice on issues such as: * How to get your child into the right school * How to get the most out of your child's teachers * How to improve your child's performance * How to work the education system for the benefit of your child
