In Butterfly Biology Systems Roger Dennis explores key topics and contentious issues in butterfly biology, specifically those in life history and behaviour. Uniquely, using a systems approach, the book focuses on the degree of integration and feedback between components and elements affecting each issue, as well as the links between different issues. The book comprises four sections. The first two sections introduce the reader to principles and approaches for investigating complex relationships, and provide a platform of knowledge on butterfly biology. The final two sections deal in turn with life history and behaviour, covering key issues affecting different stages of development from eggs to adults. The book is extensively illustrated with original diagrams and models, all of which have detailed legends, produced to enhance a broader understanding, and to provide templates for future research. It includes a detailed bibliography and glossary providing an essential gateway to the extensive literature on butterfly biology. Butterfly Biology Systems is essential reading for graduate students and researchers in insect ecology, evolution, behaviour and conservation. It will also be of great value to anyone interested in butterflies. Introduces a systems approach to butterfly biology Includes succinct reviews of the key interrelationships in butterfly life history and behaviour Illustrates more than 100 models to advance research into butterfly biology systems

The abuse of alcohol presents a major health problem throughout the world. Until recently both clinical and research efforts have been geared toward treatment and rehabilitation of alcoholism. With the growing num ber of problem drinkers entering treatment, the need for a better under standing of the prevention of alcohol abuse has become increasingly evi dent. Although still in its infancy, the field of alcoholism prevention is growing at a rapid rate. Increasing numbers of behavioral scientists through out the world are conducting or planning prevention projects. Policy plan ners, school administrators, military agencies, community groups, state and local alcoholism agencies, and industries are initiating alcohol abuse preven tion programs with fervor. Legislators at all levels of government are also developing a keen interest in legislation aimed at reducing the extent of problem drinking. This book represents one of the first systematic attempts to compile a comprehensive text on the prevention of alcohol abuse. Many of the con tributors to Prevention 0/ Alcohol Abuse have international reputations that strengthen their understanding of the complex nature of prevention. By providing a critical review of the current knowledge about prevention, the text will serve to stimulate and lay the groundwork for further prevention efforts. We thank all of the chapter authors for their excellent contributions. It is through their efforts that the field will thrive. Our appreciation also is expressed to Leonard Pace, formerly of Plenum Press, for his encourage ment and helpful comments in the development of the text."

Proceedings of a conference of experts on cocaine addiction, this early volume documents the devastating effects of crack, then a new cocaine preparation, and its extraordinary addicting properties. The Bahamian experience with crack provided an early warning about the extreme personal and social dangers of this drug .

A critical companion of zoosemiotics is the first attempt to systematise the study of animal communication and signification through its most important and/or problematic terms and concepts, and its most representative scholars. It is a companion, in that it attempts to cover the entire range of key terms in the field, and it's critical, in that it aims not only to describe, but also to discuss, problematise and, in some cases, resolve, these terms.

The topic of animal motivation deals with how and why animals engage in particular activities: what mechanisms inside the animal generate behaviour, how stimuli from the external environment in fluence these mechanisms, and how this behaviour is beneficial to the animal. The topic is thus central both to academic studies in psychology and zoology and to applied matters in domestic species. Motivation has not been an area of great emphasis in the past 10-15 years but there is now a growing realization that it should receive greater attention. Drawing on concepts and observations from a number of areas, this book provides an overview of the motiva tional processes which determine the choices, timing, and sequencing which are characteristic of animal behaviour. Data and theory from ethology, psychology, and evolutionary biology are synthesized into a contemporary framework for analysing such central features of behaviour as persistence in activities and goal orientation. Principles of motivational analysis are discussed and illustrated with specific case studies. The successive chapters deal with ethological, phy siological, and ecological approaches involving experimental work on a diversity of vertebrate and invertebrate species. Ethological topics include the interaction of external stimuli and internal states, mechanisms of choice, quantitative models of motivation, conflict between tendencies for different activities, and behavioural homeos tasis. The review of physiological research focuses on hunger, the activating roles of nerves and hormones, and the examination of animals with small nervous systems."

If the reader will excuse a brief anecdote from my own intellectual history, I would like to use it as an introduction to this book. In 1957, I was a sophomore at an undergraduate liberal arts college major ing in medieval history. This was the year that we were receiving our first introduction to courses in philosophy, and I took to this study with a passion. In pursuing philosophy, I discovered the area called "philosophical psychology," which was a Thomistic category of inquiry. For me, "philosophical psychology" meant a more intimate study of the soul (psyche), and I immediately concluded that psychology as a discipline must be about this pursuit. This philosophical interest led me to enroll in my first introductory psychology course. Our text for this course was the first edition of Ernest Hilgaard's Introduction to Psychology. My reasons for entering this course were anticipated in the introductory chapter of Hilgaard's book, where the discipline and its boundaries were discussed, and this introduction was to disabuse me of my original intention for enrolling in the course. I was to learn that, in the 20th century, people who called themselves psychologists were no longer interested in perennial philosophical questions about the human psyche or person. In fact, these philosophical questions were considered to be obscurantist and passe. Psychology was now the "scientific" study of human behavior. This definition of psychology by Hilgaard was by no means idiosyncratic to this introductory textbook."

This volume is the eighth in the Research Advances Series and the fifth published by Plenum Press. The purpose of the series is to review new work in rapidly changing fields. We do not expect reviews to cover the whole field of work on alcoholism and addiction. Nor do we expect that they will be like annual reviews covering all work in a delimited field. Our reviews are designed to explore only the most exciting parts of the total field and to focus on conclusions that can be made about them. The series publishes one volume each year. Volume 8 is an omnibus rather than a theme volume in that a wide range of topics is covered, including research on alcohol, opiates, and tobacco. As usual, the greater emphasis is on alcohol research, reflecting the importance of the problem and the volume of work to be reviewed. With Volume 8 come some changes in the Editorial Board. It will be the last volume in the series for Robert E. Popham who has resigned from the Board. He has been with the series since its inception and has contributed a great deal to its development. The members of the Board are grateful for his help. We are adding two new members: Dr. Howard Cappell, whose field is experimental psychology, and Dr. Edward M. Sellers, in clinical medicine and pharmacology.

In the past twenty years there have been many new developments in the study of animal behaviour: for example, more sophisticated methods of neurophysiology; more precise techniques for assessing hormonal levels; more accurate methods for studying animals in the wild; and, on the functional side, the growth of behavioural ecology with its use of optimality theory and game theory. In addition, there has been a burgeoning number of studies on a wide range of species. The study of aggression has benefited greatly from these develop ments; this is reflected in the appearance of a number of specialized texts, both on behavioural ecology and on physiology and genetics. However, these books have often been collections of papers by spe cialists for specialists. No one book brings together for the non specialist all the diverse aspects of aggression, including behavioural ecology, genetics, development, evolution and neurophysiology. Neither has there been a comparative survey dealing with all these aspects. Therefore one of our aims in writing this book was to fill in these gaps. Another of our aims was to put aggression into context with respect to other aspects of an animal's lifestyle and in particular to other ways in which animals deal with conflicts of interest. Aggressive behaviour does not occur in a biological vacuum. It both influences and is influenced by the animal's ecological and social environment, so we consider both the complex antecedent conditions in which aggressive behaviour occurs, and its ramifying consequences in the ecosystem."

Each of the three great schools of developmental psy- chology represented in this vo1ume--psychoana1ytic, cogni- tive-developmental, and Vygotskian--diverges in important ways. But more recent changes in each discipline have led to new possibilities for theoretical integrations. Each ori- entation has begun to focus upon the problem of "meaning construction", that is, how a person's subjectivity and con- sciousness is created through his interaction with signifi- cant others. Each discipline also discovered that as it switched to meaning and interpretation as the foci of their work, they had to reformulate and, in some cases, reject po- sitions taken by their founding figures. The papers in this volume attempt to describe the newest developments in each of these fields and to foster a theoretical dialogue around the concept of the self. The papers in this book emerged out of discussions at a Conference on the Self, sponsored by the Center for Psychosocial Studies in Chicago. For the psychoanalytic and cognitive-developmental ap- proaches, we can observe a transition from what we call the bio10gism of both traditional Freudian and Piagetian memta- psychologies to a more "communicative-interactionist" point of view. Psychoanalysts have focused on the subjective expe- rience of their patients as constituting a reality in its own right, and therefore have always focused upon problems of communication and interpretation. But Freud's emphasis on bio-sexua1 development led him to create a metapsycho1ogy in which the basic organizing principle is that of drive re- duction.

One of the most obvious changes that has occurred in behavioural biology in recent years is that it has become conspicuously a problem orientated subject. Moreover, one of the most impor tant consequences of this has been to stimulate interdisciplinary links between evolutionary biology, zoology, ecology, anthro pology and psychology. The time is now right to ask questions which relate whole animals in the contexts of their ecosystems, with their social behaviour and development, with their perceptual and cog nitive capacities. These are new ways of looking at old problems, but we are still at the stage of finding out what kinds of questions to ask. For several years now I have been involved in teaching behavioural biology to students of psychology as well as zoology, and have greatly appreciated the opportunity to relate material across many different subject areas. It is the interfacing of prob lems, as in ecology and psychology for example, that makes 'more sense' of topics such as 'intelligence', responses to 'novelty', feeding strategies and socialleaming. The aim of the book is to provide readily digestible information in a number of areas of current interest in behavioural biology. Above all, it is intended to provide a basis for discussion and further inquiry."

InJuly 1982 the first Dartmouth workshop on the corpus callosum took place. A nucleus of basic and clinical scientists was convened to give progress reports of their work on the corpus callosum. This text was subsequently compiled by the various participants from these reports modified by a stimulating cross fertilization of ideas and subsequent studies. Four and one-half decades have intervened since Van Wagenen first sectioned the corpus callosum for epilepsy (Van Wagenen and Herren, 1940) and Erickson (1940) demonstrated that the corpus callosum is the major route for generalization of experimentally induced focal cortical epilepsy. During the succeeding 45 years a handful of clinicians has pursued these leads to confirm the therapeutic value of callosotomy for some types of medically intractable generalized epilepsy. Parallel experimental studies with a number of epilepsy models have indicated that the corpus callosum is indeed the major route for seizure generalization, that the brainstem is a secondary and more resistant pathway for seizure generalization, and that most if not all epileptic seizures originate from the cerbral cortex. The unexpected clinical finding that even partial (focal) seizure incidence is modified by callosotomy now has been demonstrated in the laboratory. The various contributors to the clinical and experimental epilepsy sections of this volume have been seminal in these elucidations, as will be evident from their chapters. The section on the development, anatomy, and physiology of the corpus callosum demonstrates that these basic areas of study have not been neglected.

In recent years there has been a rapid increase in the understanding of communication between animals and this is perhaps especially true of bio-acoustics. In the last 35 years a completely new branch of bio acoustics, involving ultrasounds, has been made possible by technical developments that now allow these inaudible sounds to be detected and studied. This subject has a personal fascination for the authors, perhaps because of the novelty of 'listening in' to these previously unknown sig nals, perhaps because of the wide variety of ways in which different animals use them. Many studies of different aspects of animal ultrasound have now been published and a review of them all seems to be timely. Ultrasound is is biologically arbitrary; other animals defined in human terms and may produce similar signals at lower frequencies for similar purposes. This book attempts to be comprehensive but the limits of the subject are rather difficult to define. It should be read in conjunction with other books on audible bio-acoustics. Each chapter has been written and may be read as a separate entity, although there is considerable cross-referencing. Chapters 1 and 2 form a common introduction and may help in understanding the later sections. The Appendix is not essential but is included for those who may be interested in the quanti tative aspects of the echo-location phenomena described in Chapters 3 and 8.

"Continuities and Discontinuities in Development" was the theme for the Second Biennial DPRG Retreat, a three-day meeting held at Estes Park, Colorado, in June 1982. The meeting was sponsored by the Devel opmental Psychobiology Research Group (DPRG) of the Department of Psychiatry at the University of Colorado School of Medicine. The DPRG is a group of individuals conducting research in many areas of develop ment who meet on a regular basis to present and discuss their work and receive feedback and encouragement. In 1974, this group was awarded an endowment fund by the Grant Foundation, the aims of which were to facilitate the research of young investigators, to encourage new re search, and to provide seed money for collaborative ventures. Much of the work reported in this volume and in the earlier volume from the First DPRG Retreat is the result of that support. In addition to the work of the members of the DPRG, a select group of guests was invited to participate in the meeting and contribute to this volume. The chapters by William Greenough, Jerome Kagan, and Michael Rutter result from the participation of these scholars at the retreat. We would like to acknowledge the support of a number of indi viduals who have been instrumental in supporting the DPRG as a whole, as well as those who contributed directly to the Second Biennial Retreat and to the volume."

This volume has come about as a direct result of a Symposium entitled "Experimental Analysis of Insect Behaviour" which was an important con tribution to the 14 International Congress of Entomology held in Canberra, Australia, in August 1972 under the joint sponsorship of the Australian Academy of Science and the Australian Entomological Society. It is not, however, strictly Symposium proceedings. I have included, in this volume contributions from several workers who had to withdraw from the Symposium at a fairly late stage. Furthermore, quite intentionally, a number of the contributions bear only a general relationship to the papers given at the Congress. To permit this; the deadline for contribu tions was set at some six months after the Symposium. I imposed no restrictions on the form of the contributions. I did, however, indicate that speculative reviews highlighting the author's own recent research or that of his immediate colleagues would be particularly acceptable, and a number of the contributors have taken the opportunity to write this kind of paper. Several contributors, notably those whose task it was to give more general papers in the Symposium itself, have written reviews of somewhat greater scope."

Overview of current trends in the psychology of motivation and volition, covering basic research as well as developmen- tal and applied aspects. Intention and volition are consi- dered in chapters on behavior dynamics, self-regulation, and control over intention and actions.

Wolves are charismatic emblems of wilderness. Dogs, which descended from wolves, are models of urbanity. Do free-ranging dogs revert to pack living or are their societies only reminiscent of a wolfish heritage? Focusing on behavioral ecology, this is the first book to assess societies of both gray wolves and domestic dogs living as urban strays and in the feral state. It provides a comprehensive review of wolf genetics, particularly of New World wolves and their mixture of wolf, coyote and dog genomes. Spotte draws on the latest scientific findings across the specialized fields of genetics, sensory biology, reproductive physiology, space use, foraging ecology and socialization. This interdisciplinary approach provides a solid foundation for a startling and original comparison of the social lives of wolves and free-ranging dogs. Supplementary material, including a full glossary of terms, is available online at www.cambridge.org/9781107015197.

In addition to filling a need within the field of parental behavior, this book contributes importantly to the growing area of emotional and motivational neuroscience. A major part of neuroscience research at the whole organism level has been focused on cognitive neuroscience, with an emphasis on the neurobiology of learning and memory, but there has been a recent upsurge in research which is attempting to define the neural basis of basic motivational and emotional systems which regulate such behaviors as food intake, aggression, reproduction, reward-seeking behaviors, and anxiety-related behaviors. In this book the emphasis is on the research findings obtained from rodents, sheep and primates. The authors' goal, of course, was to provide a foundation that may help us understand the neurobiology of human parental behavior. Indeed, the last chapter attempts to integrate the non-human research data with some human data in order to make some inroads toward an understanding of postpartum depression, child abuse, and child neglect. Clearly, motivational and emotional neuroscience has close ties to psychiatry, and this connection will be very evident in the final chapter. By understanding the neurobiology of parental behavior we are also delving into neurobiological factors which may have an impact on core human characteristics involved in sociality, social attachment, nurturing behavior, and love. In this very violent world, it is hard to conceive of a group of characteristics that are more worthy of study.

In 1971 I published a review of ichnology other concentrating only on traces made (Houston AAPG: SEPM Trace Fossil Field by a certain group of organisms, regardless Trip Guidebook) that I thought could be of their setting. Nevertheless, needless re dundancy has hopefully been eliminated. expanded rather easily into a worthwhile Some of the chapters are more special book on the subject.

But we hope hand experience with virtually every aspect that all of the chapters will prove to be use of the field.

The primary goal of this volume is to advance the conceptual unification of primatology and the other evolutionary sciences by addressing the evolution of behavioral flexibility in the Primate Order. One of the first lessons learned in introductory statistics is that events in the world vary. However, some species exhibit a greater range of phenotypic plasticity, including behavioral flexibility, than others. Primates are among those taxa advanced to display an uncommon degree of behavioral diversity. The proposed volume would explore the behavioral ecology and evolution of behavioral flexibility in primates in relation to the optimization of survival, (inclusive) reproductive success, and phenotypic influence.

Behavioral Flexibility in Primates: Causes and Consequences proposes that genetic conflicts of interest are ubiquitous in primates who may employ force, coercion, persuasion, persistence, scrambles, cooperation, exploitation, manipulation, social parasitism, dispersal or spite to resolve or manage them. Where one individual or group imposes severe costs to inclusive fitness or to the phenotype upon another individual, the latter may adopt a counterstrategy in an attempt to minimize its own costs. Counterstrategies may, in turn, impose costs upon the original actor(s), and so on, possibly yielding an evolutionary "chase" ("interlocus contest evolution"). The evolution of phenotypic plasticity in primates may often pertain to attempts to mitigate genetic conflicts of interest, and classic work in behavioral ecology leads to the conclusion that for females ("energy-maximizers"), conflict will pertain primarily to competition for food (that can be converted to offspring) while, for males ("time-minimizers"), conflict will pertain primarily to competition for mates. These related and novel perspectives are developed in this new volume.

Basic Issues in Rehabilitation of the Brain Damaged Definitions Because of the vagueness surrounding the term brain damage, it is nec essary at the outset to define the population to which this book may have some application. Although it is usual to speak of the brain damaged patient in a general way, the conditions referred to cover a variety of specific disorders. In this book we will be discussing only individuals who become brain-damaged as adults. We will be ad dressing ourselves specifically to adults who have sustained demon strable, structural brain damage. Those conditions in which brain dys function is a possible etiological agent, such as a number of functional psychiatric disorders, will not be considered. Thus the entire topic of mental retardation and early life brain damage will not be treated here, nor the many problems associated with minimal brain damage syn dromes in school age children. Modern psychiatric thinking has tended to blur the distinction between the so-called functional and organic disorders (d. Shagass, Gershon, & Friedhoff, 1977), but we would ad here to the view that the patient with structural brain damage contin ues to present relatively unique assessment and treatment problems. Furthermore, the emphasis of this book will be placed on individ uals with nonprogressive, chronic brain damage."

Over the last several decades, the remarkable success of science and medical technology has allowed many children with chronic illness and handicapping conditions to live longer and healthier lives. But this suc cess is not without toll. The human cost of chronic illness or a handicap ping condition can be enormous for the child and the family. For the family, there is often the stressful daily burden of care, fatigue, marital stress, low family morale, financial burdens, and reduced career mobili ty. For the child, there are often arduous and painful treatment regimes, frequent school absences, low energy periods, and uncertainties with respect to future education and vocation. The course of many diseases is unpredictable, and the very fact of chronicity implies ongoing coping problems for the family and the child. The impact of a chronic illness or handicapping condition on a family system is usually more disintegrative than integrative, disrupting the lives of all family members and exacerbating the developmental risks to the child. It is not surprising that a recent comprehensive study for establish ing public policies for children with chronic illness at Vanderbilt Univer sity has called attention to these factors and produced, as a primary recommendation, increased attention to the psychological impact of dis ease on the family and the child. In this context there is an important need for adequate assessment of psychological and behavioral problems in these children to plan for appropriate services."

In order to communicate, animals send and receive signals that are subject to their particular anatomical, psychological, and environmental constraints. This SHAR volume discusses both the production and perception of acoustic signals. Chapters address the information that animals communicate, how the communication is developed and learned, and how communication systems have adapted and evolved within species. The book will give examples from a variety of species.

This volume details the different ways that nocturnal primates avoid predators. It is a first of its kind within primatology, and is therefore the only work giving a broad overview of predation nocturnal primate predation theory in particular in the field

Additionally, the book incorporates several chapters on the theoretical advances that researchers studying nocturnal primates need to make.

This volume brings together leading researchers on quality of life in old age to focus on one of the most important issues in both gerontology and quality of life studies. Quality of life is a holistic construct and assessed from many different perspectives and by many disciplines. Moreover, the concept of quality of life can be applied to practically all important domains of life. Thus, quality of life research has to include social, environmental, structural, and health related aspects and be approached from an interdisciplinary perspective. Recently research in gerontology has begun to systematically study quality of life - following the WHO dictum 'years have been added to life and now the challenge is to add life to years' - however there are very few texts available on this topic and none of an international and multi-disciplinary nature. Quality of life studies have neglected older people and, given the size and growth of this population, it is time to publish a volume on this topic that systematically pursues a comprehensive perspective and includes theoretical approaches and empirical findings with respect to the most important components of quality of life in old age. For these reasons and the high quality of the authors we have assembled, this will be a seminal text for both gerontology and quality of life researchers.
