Chronobiology is the study of timing mechanisms in biological systems as diverse as plants, animals and some micro-organisms. It includes rhythmic phenomena ranging from short period (ultradian) through daily (circadian) to long period (monthly, annual) cycles of behaviour, physiology and biochemistry. In recent years spectacular advances have been made, particularly in the field of circadian rhythms, and hardly a week passes without important papers appearing in the major scientific journals. The third edition of Insect Clocks , like its predecessors, deals with the properties and functions of clock-like processes in one of the planet's most abundant groups of organisms. The first half of the book is concerned with circadian rhythmicity, the second with annual responses such as over-wintering diapause, seasonal morphs and cold hardiness. Insect Clocks puts modern developments in these fields into a secure framework of the 'classical' literature that has defined the subject. The book is directed at active researchers in the field as well as newcomers and scientists working in many other areas of modern biology. It will also serve as a textbook for advanced and less advanced students and should find its way into university libraries wishing to keep abreast of the times. more...

Electrochemical reactions make significant contributions to organic synthesis either in the laboratory or on an industrial scale. These methods have the potential for developing more "green" chemical synthesis. Over recent years, modern investigations have clarified the mechanisms of important organic electrochemical reactions. Progress has also been made in controlling the reactivity of intermediates through either radical or ionic pathways. Now is the time to gather all the electrochemical work into a textbook. As an essential addition to the armory of synthetic organic chemists, electrochemical reactions give results not easily achieved by many other chemical routes. This book presents a logical development of reactions and mechanisms in organic electrochemistry at a level suited to research scientists and final year graduate students. It forms an excellent starting point from which synthetic organic chemists, in both academia and industry, can appreciate uses for electrochemical methods in their own work. The book is also a reference guide to the literature. more...

Leading experts in the field bring together diverse aspects of insect timing mechanisms. This work combines three topics that are central to the understanding of biological timing in insects: circadian rhythms, photoperiodism, and diapause. The common theme underlining each of the contributions to this book is an understanding of the timing of events in the insect life cycle. Most daily activities (emergence, feeding, mating, egg laying, etc.) undertaken by insects occur at precise times each day. Likewise, seasonal events such as the entry into or termination from an overwintering dormancy (diapause) occur at distinct times of the year. This book documents such events and provides an up-to-date interpretation of the molecular and physiological events undergirding these activities. The study of circadian rhythms has undergone a flowering in recent years with the molecular dissection of the components of the circadian clock. Now that many of the clock genes have been identified it is possible to track daily patterns of clock-related mRNAs and proteins to link the entraining light cycles with molecular oscillations within the cell. Insect experiments have led the way in demonstrating that the concept of a "master clock" can no longer be used to explain the temporal organization within an animal. Insects have a multitude of cellular clocks that can function independently and retain their function under organ culture conditions, and they thus offer a premier system for studying how the hierarchical organization of clocks results in the overall temporal organization of the animal. Photoperiodism, and its most obvious manifestation, diapause, does not yet have the molecular underpinning that has been established for circadian rhythms, but recent studies are beginning to identify genes that appear to be involved in the regulation of diapause. Overall, the book presents the rich diversity of challenges and opportunities provided by insects for the study of timing more...
