Book Description
The Novartis Foundation Series is a popular collection of the proceedings from Novartis Foundation Symposia, in which groups of leading scientists from a range of topics across biology, chemistry and medicine assembled to present papers and discuss results. The Novartis Foundation, originally known as the Ciba Foundation, is well known to scientists and clinicians around the world.

Book Description
Photoperiodism, melatonin and the pineal Ciba Foundation Symposium 117 Chairman: R.V. Short 1985 Melatonin was isolated from the mammalian pineal in 1985, but only relatively recently, as the Chairman points out, has evidence accumulated for its role as ‘the Hormone of Darkness, the Hourglass of Time’. The rhythmic melatonin signal from the pineal appears to provide information about photoperiod in many species that show seasonal cycles in reproduction, moulting and other processes. But how do animals respond to the pineal melatonin signal? What determines photoperiodism in birds, which do not seem to use this signal to regulate breeding? What is the significance of retinal melatonin? Does melatonin have a function in humans? These are amongst the issues considered at the symposium recorded in this book. In addition to the morphology and photoneural control of the pineal, the contributors describe the effects of melatonin and of manipulating photoperiod in several laboratory and economically important species — hormones, seasonal cycles, circadian rhythms and influences during development and sexual maturation have been studied. In humans, the possible significance of melatonin in puberty, malignant disease and affective disorders is considered, as are results suggesting that melatonin can entrain fatigue (or alertness), with discussion of the therapeutic potential of this hormone in certain disturbances of biological rhythm, including jet lag. This book should be of interest to physiologists, neuropharmacologists, endocrinologists, behavioural biologists, psychologists and clinical investigators with a special interest in the pineal.

Book Description
Reflects on insect pests' evolution by evaluating existing theories, documenting case studies of diverse pest species and presenting new concepts regarding the problem of variation and implications for pest management strategies. Leading experts offer contributions which deal with variations in genetic markers and ecologically meaningful traits as well as future perspectives in entomology and biosystematics.

Book Description
Coccinellids have been very actively studied in the course of the twenty three years since "Biology of Coccinellidae" was published. The great amount of new, and often very important findings have made the previous book outdated and a new synthesis is needed. No other monograph of similar focus and extent has appeared. Iablokoff Khnzorian's "Les Coccinelles" (1982), limited to the tribus Coccinellini, and Gor don's "The Coccinellidae of America North of Mexico" (1985) both concentrate on taxonomy. Majerus' beautiful "Ladybirds" (1994) deal specifically with British coc cinellids and address chiefly amateur naturalists. The focus and the title of the recent book are slightly different from the 1973 vol ume. If a satisfactory comprehensive review of important new findings is attempted, the book would grow too much, due also to References and Indexes. To keep the vol ume at a tolerable extent, the section on larval identification of Palaearctic species has been omitted; not much could be added to the previous version of that part, any way. However, we have kept Kovar's chapter on morphology and anatomy, because of its relation to feeding and other ecological aspects. The chapter on phylogeny was updated also by him. Our Polish friend, Piotr Ceryngier, who has recently specialised in parasites, updated perfectly the parts on parasites and pathogens in Chapter 8. We would be glad if their contribution is quoted by their names. It seems to us that the remarks, contained in the reprinted preface to the previous volume, remain pertinent today.

Book Description
An intriguing class of biological periodicity consists of rhythms with about 24-hour periods occurring at every level of eukaryotic organization. Progress is being made in understanding these rhythms. The six chapters of this work include a brief introduction to circadian (24-hour) rhythms, a survey of circadian organization at the cellular level, and a description of the important microorganisms that have served as experimental models for biochemical analysis. Also considered are relations between cell division cycles and circadian oscillators, as well as some general and theoretical aspects. Where appropriate, parallels are drawn to neuronal oscillators. This volume will introduce and critically appraise modern chronobiology; its extensive illustrations and comprehensive up-to-date bibliography will make it an authoritative reference.
