As time progresses, biology becomes more and more fragmented and specialized and it becomes increasingly difficult to see how all the dis- ! parate facts fit together. It is completely proper that biologists should have sought to reduce complex biological wholes into their parts, and it is natural that studies on the products of this reduction should have diverged from more holistic studies on evolution and ecology. Yet the biological parts, what they do and how they are organized are products of an evolutionary process which fits organisms for life in particular ecological circumstances. Physiology, developmental biology, ecology and evolutionary biology must not be allowed to grow too far apart, therefore, because all these disciplines and the way their subject matters interact are crucial to understanding organisms - and it is this, it seems to me, which is the fundamental goal of the biological sciences. This book has been written in the spirit of unification and synthesis. It is, in a sense, a general biology of the organism - not, however, of organisms as static unchanging systems, but of organisms as dynamic entities which progress through a definite cycle of events from birth to maturity. The central theme, therefore, will be the life cycle, and the book is organized around the three main phases which are characteristic of all life cycles; growth (Part II), reproduction (Part III) and ageing (Part IV).

This text integrates the treatment of groups of animals phylum by phylum with a functional approach to the various invertebrate anatomical and physiological systems of the better known species. It integrates a discussion of the evolutionary history of invertebrates with an illustrated description of all known invertebrate phyla. It distills the essential characteristics of each group with which the student should be familiar and lists diagnostic features to allow comparison between phyla. Form and function are presented from an evolutionary viewpoint in the light of selection pressures and advantages which are associated with different body plans, life-history and behaviour. This edition contains a new chapter on protozoa, expanded details on parasitism, the economic exploitation of invertebrates and size, shape and scaling. It also includes many new illustrations and the format of the book has been changed to offer students a more clear and accessible page layout.

Progress in Standardization of Aquatic Toxicity Tests provides a critical evaluation of the level of standardization achieved by freshwater and marine ecotoxicity tests used to evaluate potential risk of new chemicals and wastewater effluents. Tests at the sub-cellular, individual, laboratory microcosm, and ecosystem levels are presented and critically evaluated. The influence of environmental and genetic heterogeneity on test standardization is also discussed. The book will be an excellent reference for industry professionals, consultants, regulatory officials, and students working in the ecotoxicology field.

It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
