Most people who have taken a biology course in the past 50 years are familiar with the work of David Lack, but few remember his name. Almost all general biology texts produced during that period have a figure showing the beak size differences among the finches of the Galapagos Islands from Lack's 1947 classic, Darwin's Finches. Lack's pioneering conclusions in Darwin's Finches mark the beginning of a new scientific discipline, evolutionary ecology. Tim Birkhead, in his acclaimed book, The Wisdom of Birds, calls Lack the 'hero of modern ornithology.' Who was this influential, yet relatively unknown man? The Life of David Lack, Father of Evolutionary Ecology provides an answer to that question based on Ted Anderson's personal interviews with colleagues, family members and former students as well as material in the extensive Lack Archive at Oxford University.

This book is a collection of papers given by invited speakers at a Symposium on 'Feedback and Motor Control', held at the University of Glasgow from July 10th to 13th 1984, which was attended by over 200 scientists from 20 countries. The Symposium was the Fourth International Symposium organised by the Scottish Electrophysiological Society (SES), and on this occasion the SES joined forces with the Society for Experimental Biology (SEB), so that the Symposium was held dur ing the annual Summer Meeting of the SEB. A policy of the SES since its formation in 1970 has been to promote dialogue between scientists working on invertebrate and vertebrate nervous systems by hol

In review, the amount of information available on the morphological and func tional properties of the frog nervous system is very extensive indeed and in certain areas is the only available source of information in vertebrates. Further more, much of the now classical knowledge in neurobiology was originally ob tained and elaborated in depth in this vertebrate. To cite only a few examples, studies of nerve conduction, neuromuscular transmission, neuronal integration, sense organs, development, and locomotion have been developed with great detail in the frog and in conjunction provide the most complete holistic descrip tion of any nervous system. Added to the above considerations, the ease with which these animals may be maintained (both as adults and during development) and the advantage of their lower cost as compared with other vertebrate forms make the frog one of the most important laboratory animals in neurobiology. With these thoughts in mind, we decided to compile this volume. Our goal in doing so was to assemble as much as possible of the information available on frog neurobiology and to have the different topics covered by authorities in each of the fields represented. To keep the handbook restricted to one volume, we found it necessary to omit the large field of amphibian muscle neurobiology, which has already been summarized in various other publications."

Fishes are very successful vertebrates and have adapted to a wide range of environmental conditions, from the deep ocean to the smallest brook or pond. The physiological background to these environmental adaptations is, obviously, far from clear, and provides fish physiologists with many challenges. The number of extant fish species has been estimated to be in excess of 20000, and only relatively few of these have been subject to physiological studies. Yet among these animals can be found many physiological systems different from those of the land-dwelling vertebrates, and also systems similar to those of the 'higher' vertebrates but at a different level of phylogenetic development. Apart from the rapidly increasing interest in basic fish physi ology, the last few years have seen a dramatic increase in applied research, aimed primarily in two directions: fish culture and envi ronmental toxicology. Physiological research is of vital importance in both these fields, and basic fish physiology is a necessary base for the applied research. This book is intended for a wide readership among senior undergraduate, postgraduate and research students, as well as uni versity teachers and researchers in zoology, physiology, aqua culture and biology generally. The book focuses on five major areas of basic and applied research: haemopoiesis, acid-base regu lation, circulation, gastro-intestinal functions and physiological toxicology. The chapters will serve as introductions to these fields, as well as up-to-date reviews of the most recent advances in the research areas."

In this book, concerned with the spatial and structural repre- sentation of the cell and its particular specializations, the author hasdeviatedconsiderablyfrom the usual planfor other books related to this subject and has presented the illustrative material in the form of detailed and accurate drawings. The layout of the book provides the reader with a briefnarrative accountoftheparticularorganelleaccompanied byafull-plate illustration on the facing page. Most ofthe narrative accounts areaccompaniedbyashortbibliographyofgermanereferences in the event the reader desires to pursue the subject matter in greater depth. In my estimation there is no other presentation currentlyavailablewhich utilizes thisapproach to demonstrate the cellular components and their associated morphophysi- ology with such elegance. Thetextisclearlywrittenand,althoughtheindividualaccounts are brief, they are highly informative with all ofthe important details being provided. The accuracy ofthe textural presenta- tions and the continuity ofexpression provide strong evidence that the author has spent an enormous amount of time in preparing the text and in painstakingly drawing the illustra- tions. Certainly, an obvious strength ofthis volume is the high qualityoftheillustrativerenditions, allofwhichweredrawnby Dr. KRSTIC. These attest to the profound and comprehensive nature of the author's knowledge of the field of cellular and structural biology. This book is truly a work oflove and art by one who is gifted both didactically and artistically. Dr. KRSTIC should be con- gratulated for providing us with an extremely accurate and detailedaccountofthe 2-dimensional, andinmanycasesthe 3- dimensional, view of the cell and its component organelles. It has no equal.

The neotropical primate family Pitheciidae consists of four genera Cacajao (uacaris), Callicebus (titis), Chiropotes (bearded sakis) and Pithecia (sakis), whose 40+ species display a range of sizes, social organisations, ecologies and habitats. Few are well known and the future survival of many is threatened, yet pitheciines have been little studied. This book is the first to review the biology of this fascinating and diverse group in full. It includes fossil history, reviews of the biology of each genus and, among others, specific treatments of vocalisations and foraging ecology. These studies are integrated into considerations of current status and future conservation requirements on a country-by-country basis for each species. A state-of-the-art summary of current knowledge, Evolutionary Biology and Conservation of Titis, Sakis and Uacaris is a collective effort from all the major researchers currently working on these remarkable animals.

This volume offers a state-of-the-art overview of plethodontid salamanders. Readers will find the best current understanding of many aspects of the evolution, systematics, development, morphology, life history, ecology, and field methodology of these animals.

The Chapman and Hall Fish and Fisheries Series occasionally includes books devoted to a single taxon of fish that are of particular interest to fish and fisheries science. All three previous books of this type (Cichlid Fishes, Cyprinid Fishes, Sea Bass) have included important material on commercial fishery exploitation, but Hake: Biology, fisheries and markets, number 15 in the Series, is the first book that focuses on a major global fishery resource. This book brings together detailed analyses of the ocean habitats, biology, ecology, assessment and management of all the hake fisheries of the world for the first time. Globally, there are ten major world fisheries for 12 species of hake on both sides of the North and the South Atlantic, the Mediterra nean, the eastern North and South Pacific and New Zealand. The book includes an overview of industrial markets and products of hake. Hake fisheries are of particular economic interest as their location spans almost a complete spectrum of industrial development from major industrial countries like USA, Canada, Spain and Italy through New Zealand, South Africa, Argentina and Chile to Morocco, Peru, Mauritania, Namibia and Angola."

The originality of this volume is to reveal to the reader the fascination of some unfamiliar sensory organs that are sometimes ignored and often misunderstood. These receptors have only recently been identified and their functional specificity is in some cases still a matter for discussion. The four classes of sensory organs considered here differ widely from one another in many respects. One might even say that the only thing they have in common is that they belong to cold-blooded vertebrates. These classes are: 1. the directionally sensitive lateral-line mechanoreceptors of fishes and amphi bians (Chapter 7); 2. the pseudobranchial organs of some teleosts, equipped with pressoreceptors and at least three other types of receptors (osmo- and chemoreceptors) (Chapter 8); 3. the infrared-sensitive pit organs of some snake families (Chapter 9); 4. the various kinds of electroreceptors found in several marine and freshwater fish families (Chapters 2 to 6). The first three classes of receptors mentioned above thus rate only one chapter each, whereas five chapters are devoted to the electroreceptors. Electroreception has aroused enormous interest among physiologists in specialties ranging from molecular biology to animal behavior. The resulting quantity of research and discussion fully justifies this disproportion. However, it cannot be denied that the contents of the volume must appear unbalanced and heterogeneous, yet it should not be perceived as a mere juxtaposition of particular and unrelated cases."

Although consensus exists among researchers that birds evolved from coelurosaurian theropods, paleontologists still debate the identification of the group of coelurosaurians that most closely approaches the common ancestor of birds. The last 20 years witnessed the discovery of a wide array of avian-like theropods that has considerably amplified the anatomical disparity among deinonychosaurians, some of which resemble Archaeopteryx more than Deinonychus. Among these newly discovered theropods that show remarkable bird-like characteristics are the four-winged theropods Microraptor and Anchiornis, and the unenlagiids Unenlagia, Buitreraptor, and Rahonavis. A bizarre group of minute-sized coelurosaurs, the Scansoriopterygidae, also exhibits some avian similarities that lead some authors to interpret them as more closely related to birds than other dinosaurs. With the aim to explore the phylogenetic relationships of these coelurosaurians and birds, we merged recently published integrative databases, resulting in significant changes in the topological distribution of taxa within Paraves. We present evidence that Dromaeosauridae, Microraptoria, Unenlagiidae, and Anchiornis ] Xiaotingia form successive sister taxa of Aves, and that the Scansoriopterygidae are basal coelurosaurians not closely related to birds. The implications in the evolutionary sequence of anatomical characters leading to birds, including the origin of flight, are also considered in light of this new phylogenetic hypothesis.

This volume reviews the meaning of taxonomic statements and considers our present knowledge regarding the number and characteristics of species among living and extinct primates, including man and his ancestors. They also examine the relationship of behaviour changes and selection pressures in evolutionary sequences. First published in 1964.

The Gashaka Primate Project has grown into one of the largest research and conservation activities in West Africa. At present, it keeps going on the initiative of the editors of this volume and their academic home institutions.The appearance of this volume marks the 10th anniversary of the Gashaka Primate Project

In the denervated state the mammalian heart, both in vivo and in vitro, is excited at very regular intervals, the coefficient of variance of the interbeat intervals not exceeding 2%. The pacemaker that is the source of this regular ex citation is localised normally within the sinus node (" sino-atrial node " node of Keith and Flack), a most intriguing small piece of tissue in the caval corner of the right atrium. A small portion of this node containing a group of probably only a few thousands of cells fires spontaneously, that means without any exter nal influence to trigger their activity. The so called pacemaker cells do this by letting their membrane potential fall to the level where an action potential will start which subsequently activates surrounding cells to fire an action po tential. The first question which is tackled in this book is which processes underly this spontaneous diastolic depolarization. This is discussed in section I, concerning the fundamental properties of pacemaker cells with special refer ence to ionic membrane currents. Although views still quite differ about the exact nature of the membrane processes that cause the automatic pacemaker dis charge there is agreement that diastolic depolarization is brought about by the interaction of a number of ionic current systems, including both inward and out ward going currents."

by Dr P .H. Greenwood British Museum (Natural History), London Dr Tesch's wide ranging account of anguillid eels impinges on the interests of many biologists; it is not simply a specialized tome narrowly aimed at ichthyologists and fishery scientists, rather it provides a source of primary reference and a comprehensive sununary of informa tion that is not likely to be superseded for a long time. It is significant that the bibliography includes references to learned journals concerned with physiology, pharmacology, taxonomy, genetics, zoology, endo crinology, botany, ecology and environmental interactions. Such is the breadth of interest in the Anguillidae. Few fish species have been subjected to as detailed review as Dr Tesch gives for the (wo Atlantic species of Anguilla. An equally comprehensive resume of research into the fourteen, rather less well-studied Indo Pacific species gives balance and reciprocal illumination to several biological problems posed by these similar but quite distinctive species."

The conference represented by this book was made possible by support from NICHD and a planning committee headed by Dr. Richard Sherins. Two general areas of research are included: the first encompasses steroid hormone synthesis, metabolism and transport in the testis; and the second relates to hormonal regula tion of the seminiferous tubule with special emphasis on the con trol of Sertoli cell function. In addition, there are sections on the purification of unique testicular proteins and morpho logical studies with particular emphasis on the Sertoli cell. We would like to express our sincere thanks to Dr. Sherins and his staff at NICHD and to all of the people at the University of North Carolina who participated in the Conference arrangements, to Dr. Judson J. Van Wyk, Chief of the Pediatric Endocrinology Division, and Dr. H. Stanley Bennett, Director of the Laboratories for Reproductive Biology. Our very special thanks to Mrs. Carolyn Jaros for her help in handling the local arrangements. Mrs. Martha Byrd and Mrs. Linda Rollins typed the manuscripts. Miss Leslie Wells and Mr. Albert Smith kindly assisted in proof reading, and Dr. Elizabeth Wilson gave much help with the final editing process. To all of these people, we are most grateful."

In the last few years there has been an excltmg upsurge in seabird research. There are several reasons for this. Man's increased ex ploitation of natural resources has led to a greater awareness of the potential conflicts with seabirds, and of the use of seabirds to indicate the damage we might be doing to our environment. Many seabird populations have increased dramatically in numbers and so seem more likely to conflict with man, for example through competition for food or transmission of diseases. Oil exploration and production has resulted in major studies of seabird distributions and ecology in relation to oil pollution. The possibility that seabirds may provide information on fish stock biology is now being critically investigated. Some seabird species have suffered serious declines in numbers and require conservation action to be taken to reduce the chances that they will become extinct. This requires an understanding of the factors determining their population size and dynamics."

Why do people find monkeys and apes so compelling to watch? One clear answer is that they seem so similar to us-a window into our own minds and how we have evolved over millennia. As Charles Darwin wrote in his Notebook, "He who understands baboon would do more toward metaphysics than Locke." Darwin recognized that behavior and cognition, and the neural architecture that support them, evolved to solve specific social and ecological problems. Defining these problems for neurobiological study, and conveying neurobiological results to ethologists and psychologists, is fundamental to an evolutionary understanding of brain and behavior. The goal of this book is to do just that. It collects, for the first time in a single book, information on primate behavior and cognition, neurobiology, and the emerging discipline of neuroethology. Here leading scientists in several fields review work ranging from primate foraging behavior to the neurophysiology of motor control, from vocal communication to the functions of the auditory cortex. The resulting synthesis of cognitive, ethological, and neurobiological approaches to primate behavior yields a richer understanding of our primate cousins that also sheds light on the evolutionary development of human behavior and cognition.

Feeding Ecology in Apes and Other Primates focuses on evolutionary perspectives of the complex interactions between the environment, food sources, physiology and behaviour in primates. This highly interdisciplinary volume provides a benchmark to assess dietary alterations that affected human evolution by putting the focus on the diet of hominid primates. It also offers a fresh perspective on the behavioural ecology of the last common ancestor by integrating corresponding information from both human and non-human primates. The potential of innovations of applied biotechnology are also explored to set new standards for future research on feeding ecology, and new information on feeding ecology in humans, apes and other primates is synthesized to help refine or modify current models of socioecology. By taking a comparative view, this book will be interesting to primatologists, anthropologists, behavioural ecologists and evolutionary biologists who want to understand better non-human primates, and the primate that is us.

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.

Archie Carr, one of the greatest biologists of the twentieth century, played a leading part in finding a new and critical role for natural history and systematics in a post-1950s world dominated by the glamorous science of molecular biology. With the rise of molecular biology came a growing popular awareness of species extinction. Carr championed endangered sea turtles, and his work reflects major shifts in the study of ecology and evolution. A gifted nature writer, his books on the natural history of sea turtles and their habitats in Florida, the Caribbean, and Africa entertained and educated a wide audience. Carr's conservation ethic grew from his field work as well as his friendships with the fishermen who supplied him with many of the stories he retold so engagingly. With Archie Carr as the focus, The Man Who Saved Sea Turtles explores the evolution of the naturalist tradition, biology, and conservation during the twentieth century.

an attempt to rationalize these terminological and conceptual difficulties we have considered the origins of mammalian heat production from two different points of view. The scheme depicted in Fig. 1. 1 illustrates the fate of energy in the body as seen by the nutritionist. After allowing for losses of energy in faeces and urine, the metabolizable energy obtained from food is utilized for main taining and increasing body energy content (maintenance, external work, growth and production). The transformation of metabolizable energy into these forms of net energy also involves inevitable energy losses in the form of heat - thermic energy. Similarly, maintaining homeothermy in cold en vironments involves shivering and non-shivering thermogenesis (NST) and the energy costs of assimilating nutrients and retaining net energy results in obligatory heat losses due to diet-induced thermogenesis (DIT). This obligatory DIT is mainly due to the energy cost of protein and fat synthesis but, in addition to this, there is an adaptive component of DIT that helps maintain body energy content (i. e. body weight) by dissipating the metabolizable energy consumed in excess of the requirements for maintenance, growth and production. In Fig. 1. 2, we have converted this nutritionist's scheme (A) into one that A B r-------. . ., I I Production, Growth I I External work I I I I Essential energy expenditure NET BASAL Obligatory 1 I ENERGY Maintenance HEAT heat I FASTING at (BMR) productlpn for t ROC thermoneutrallty homeothermia r."

Not since F. R. Harden Jones published his masterwork on fish migration in 1968 has a book so thoroughly demystified the subject. With stunning clarity, David Hallock Secor's Migration Ecology of Fishes finally penetrates the clandestine nature of marine fish migration. Secor explains how the four decades of research since Jones' classic have employed digital-age technologies-including electronic miniaturization, computing, microchemistry, ocean observing systems, and telecommunications-that render overt the previously hidden migration behaviors of fish. Emerging from the millions of observed, telemetered, simulated, and chemically traced movement paths is an appreciation of the individual fish. Members of the same populations may stay put, explore, delay, accelerate, evacuate, and change course as they conditionally respond to their marine existence. But rather than a morass of individual behaviors, Secor shows us that populations are collectively organized through partial migration, which causes groups of individuals to embark on very different migration pathways despite being members of the same population. Case studies throughout the book emphasize how migration ecology confounds current fisheries management. Yet, as Secor explains, conservation frameworks that explicitly consider the influence of migration on yield, stability, and resilience outcomes have the potential to transform fisheries management. A synthetic treatment of all marine fish taxa (teleosts and elasmobranchs), this book employs explanatory frameworks from avian and systems ecology while arguing that migrations are emergent phenomena, structured through schooling, phenotypic plasticity, and other collective agencies. The book provides overviews of the following concepts: the comparative movement ecology of fishes and birds; the alignment of mating systems with larval dispersal; schooling and migration as adaptations to marine food webs; Natal homing; connectivity in populations and metapopulations; and, the contribution of migration ecology to population resilience.

Frederick Wollaston Hutton (1836-1905) was a geologist and a supporter of Darwinian theory. He emigrated to New Zealand in 1866, became Professor of Biology at Canterbury College, and won awards both in Britain and Australasia for his work on the natural history of New Zealand. He published scientific papers on biology and zoology as well as geology and, with James Drummond, wrote two popular works, Nature in New Zealand (1902) and The Animals of New Zealand (1904). The latter was extremely successful. It was revised and expanded the following year, and this fourth edition was published in 1923. The book focuses on native vertebrates, so the bulk of the content relates to birds, of which Hutton had published a catalogue in 1871. It also describes marine mammals, reptiles, and bats, and gives brief coverage to introduced species. There are 154 illustrations, and indexes of Maori, English and scientific names.

The subject matter of this volume was the basis for a confer ence held in Philadelphia in June, 1981, and is an important one in the contemporary area of how the host interacts with micro organisms. In conception, it grew out of a graduate course entitled, "The Infectious Process," which has been taught in the Department of Microbiology and Immunology at Temple University School of Medicine during the past twelve years. This course has explored the broad areas of mechanisms of microbial pathogenesis and host resistance by in-depth consideration of selected models of experimental infection and immunity, as well as the clinical literature. It is noteworthy that there is no adequate text for this material, as the subject matter naturally crosses a wide spectrum of traditional disciplinary lines, encompassing topics as diverse as the mechanisms of action of bacterial toxins, the role of complement and antibody in phagocytosis, and the importance of cross-reacting bacterial polysaccharide antigens in vaccine development. A major portion of the course has always considered "cellular immunity" as it applies to host defenses to intracellular pathogens. It is in this area that the necessity for amalgamation of information from different disciplines is most evident, for one must be intimately concerned with the interactions between the microbe and the phagocyte, both before and after specific immune recognition."
