Originally published in 1955, as number 4 in the Cambridge Monographs in Experimental Biology series, this book presents an account of diapause in arthropods. The text finds in the phenomenon of diapause material for an investigation of the fundamental aspects of growth. Additionally, the effect on diapause of events in the external environment are seen as important for gaining an understanding of the life cycle of 'beneficial and injurious species'. Illustrative figures are incorporated throughout. This book will be of value to anyone with an interest in arthropods, diapause and the history of science.

Assembles a collection of experts to provide a current account of different approaches (e.g., traditional, comparative and experimental) being applied to study mobility. Moreover, the book aims to stimulate new theoretical perspectives that adopt a holistic view of the interaction among intrinsic (i.e. skeletal) and extrinsic (i.e. environmental) factors that influence differential expression of mobility. Since the environment undoubtedly impacts mobility of a wide variety of animals, insights into human mobility, as a concept, can be improved by extending approaches to investigating comparable environmental influences on mobility in animals in general. The book teases apart environmental effects that transcend typical categories (e.g., coastal versus inland, mountainous versus level, arboreal versus terrestrial). Such an approach, when coupled with a new emphasis on mobility as types of activities rather than activity levels, offers a fresh, insightful perspective on mobility and how it might affect the musculoskeletal system.

Every coordination within or between animals depends on communication processes. Although the signaling molecules, vocal and tactile signs, gestures and its combinations differ throughout all species according their evolutionary origins and variety of adaptation processes, certain levels of biocommunication can be found in all animal species:  (a) Abiotic environmental indices such as temperature, light, water, etc. that affect the local ecosphere of an organism and are sensed, interpreted. (b) Trans-specific communication with non-related organisms. (c) Species-specific communication between same or related species. (d) Intraorganismic communication, i.e., sign-mediated coordination within the body of the organism. This book gives an overview of the manifold levels of animal communication exemplified by a variety of species and thereby broadens the understanding of these organisms.

This book summarizes recent advances in understanding of the mammalian and fish olfactory system and provides perspective on the translation of external odor information into appropriate motivational and behavioral responses. Following the discovery of the odorant receptor gene family in 1991, understanding of the basic biological mechanisms of the olfactory system has advanced enormously. Despite such rapid progress, however, it remains unclear how odor information is processed at levels beyond the olfactory bulb, including the olfactory cortex, olfactory tubercle, and orbitofrontal cortex. This book thus describes the most recent developments in olfactory research, with particular focus on the basic neurobiological mechanisms of the neuronal circuit function in the olfactory system and its related higher centers. Exploring the basic functional logic of the neuronal circuits in the olfactory system in this way appears to be crucial in understanding the workings of the complex neuronal circuits of the brain, particularly those in the cerebral cortex that link sensory perception to appropriate behavioral responses. This book is written for the coming generation of scientists: undergraduates, graduate students, and postdoctoral researchers in the fields of neuroscience, neurobiology, chemical senses, food and nutritional sciences, medical science, sensory psychology, and behavioral sciences.

This monograph presents complex data on Fascioloides magna from all aspects of its research (general information, distribution, spectrum of hosts) and summarizes the latest information on molecular structure of informative genes which were recently applied in resolving taxonomy and biogeography of this veterinary important parasite. The giant liver fluke, Fascioloides magna, is important liver parasite of free-living and domestic ruminants. Due to its biology, distribution, medical impact, and invasive character, this liver fluke attracts attention of wide spectrum of specialists - veterinary doctors, hunters and farmers, as well as scientists. The parasite utilizes wide range of free living and domestic ruminants as definitive hosts, with various pathological impacts ranging from moderate infections towards lethal effects. Fascioloides magna is of North American origin where it occurs in five enzootic regions. It was introduced to Europe along with its deer hosts in 19th century and it has established three permanent natural foci. The giant liver fluke represents an outstanding model for studying the origin, spatial distribution, migratory routs, and invasion processes of introduced species.

The work summarizes the current knowledge regarding the controlled reproduction of an emerging aquaculture species, the Eurasian perch (Perca fluviatilis). In great detail it describes and explains the principal of most of the controlled reproductive protocol leading to obtain high quality larvae. The book is primarily intended to be used as a hatchery manual by practicing aquaculturists and laboratory technicians working with this species. On the other hand, it also summarizes the scientific background of the methods applied, therefore, it can serve as a reference for the state-of-the-art in the controlled reproduction of Eurasian perch and other freshwater percid species.

Unchecked aggression and violence take a significant toll on society. Even if we manage to avoid being the direct victim of a violent act, the effects of aggression and violence reach us all: We hear about the mauling of a woman by an aggressive dog, our children are bullied at school, or we deal with impulsive violence while commuting to work or attending a sporting event. Reflecting psychology in general, the dominant roles of learning and environmental influences - both social and nonsocial - have traditionally been prominent in discussions of the etiology of human aggression. Biological factors have not been considered sufficiently important to investigate in the search for ways of dealing with human aggression or violence. With recent advances in pharmacology and genetic manipulation techniques, however, new interest has developed in the biological mechanisms of both non-human and human aggression. Although aggression is certainly a complex social behavior with multiple causes, molecular biological factors should not be overlooked, as they may well lead to interventions that prevent excess aggressive behaviors. The primary goal of this book is to summarize and synthesize recent advances in the biological study of aggression. As most aggressive encounters among human and non-human animals represent a male proclivity, the research in this book describes and discusses studies using the most appropriate murine model: testosterone-dependent offensive inter-male aggression, which is typically measured in resident-intruder or isolation-induced aggression tests. The research also emphasizes various molecules that have been linked to aggression tests. The research also emphasizes various molecules that have been linked to aggression by the latest gene-targeting and pharmacological techniques. Although the evidence continues to point to androgens and serotonin (5-HT) as major hormonal and neurotransmitter factors in aggressive behavior, recent work with GABA, dopamine, vasopressin, and other factors, such as nitric oxide, has revealed significant interactions with the neural circuitry underlying aggression. This book is organized according to levels of analysis. The first section examines the genetic contributions to aggression in species ranging from crustaceans to humans. The section summarizes the involvement of various neurotransmitters and neuromodulators in aggressive behavior. The third section summarizes the influence of hormones on aggression, primarily in humans. All chapters emphasize future directions for research on aggression and reveal important domains that have received comparatively less attention in this literature. Considered together, these chapters provide up-to-date coverage of the biology of aggression by some of the leading authorities currently working in this field. Biology of Aggression will direct future research to continue the recent advances in the pharmacological and genetic approaches to understanding aggression and violence. It promises to be a valuable resource for professional and student researchers in neuroscience, psychiatry, cognitive and developmental psychology, behavioral biology, and veterinary medicine.

This second edition contains cutting-edge advances in the field and is a key resource to those seeking to define the bioavailability and bioequivalence of percutaneously active compounds to improve scientific and clinical investigation and regulation.

This book addresses the impacts of current and future reproductive technologies on our world food production and provides a significant contribution to the importance of research in the area of reproductive physiology that has never been compiled before. It would provide a unique opportunity to separate the impacts of how reproductive technologies have affected different species and their contributions to food production. Lastly, no publication has been compiled that demonstrates the relationship between developments in reproductive management tools and food production that may be used a reference for scientists in addressing future research areas. During the past 50 years assisted reproductive technologies have been developed and refined to increase the number and quality of offspring from genetically superior farm animal livestock species. Artificial insemination (AI), estrous synchronization and fixed-time AI, semen and embryo cryopreservation, multiple ovulation and embryo transfer (MOET), in vitro fertilization, sex determination of sperm or embryos, and nuclear transfer are technologies that are used to enhance the production efficiency of livestock species.

Illustrative figures and a bibliography are also included. This book will be of value to anyone with an interest in the development of agriculture and the history of science.

This volume examines fish sounds that have a proven signal function, as well as sounds assumed to have evolved for communication purposes. It provides an overview of the mechanisms, evolution and neurobiology behind sound production in fishes, and discusses the role of fish sounds in behavior with a special focus on choice of mate, sex-specific and age-specific signaling. Furthermore, it highlights the ontogenetic development of sound communication and ecoacoustical conditions in fish habitats and the influence of hormones on vocal production and sound detection. Sound Communication in Fishes offers a must-have compendium for lecturers, researchers and students working in the fields of animal communication, fish biology, neurobiology and animal behavior.

The rapid progress of neuroscience in the last decade can be largely attributed to significant advances in neuroethology, a branch of science that seeks to understand the neural basis of natural animal behavior. Novel approaches including molecular biological techniques, optical recording methods, functional anatomy, and informatics have brought drastic changes in how the neural systems underlying high-level behaviors such as learning and memory are described. This book introduces recent research techniques in neuroethology, with diverse topics involving nematodes, insects, and vertebrates (birds, mice and primates), divided into sections by research method. Each section consists of two chapters written by different authors who have developed their own unique approaches. Reports of research in "model animals" including C. elegans, Drosophila, and mice, which were not typical specimens in conventional neuroethology, have been deliberately selected for this book because a molecular genetic approach to these animals is necessary for advances in neuroethology. Novel methodology including optical recording and functional labeling with reporter genes such as GFP has been actively used in recent neurobiological studies, and genetic manipulation techniques such as optogenetics also are powerful tools for understanding the molecular basis of neural systems for animal behavior. This book provides not only these new strategies but also thought-provoking statements of philosophy in neuroethology for students and young researchers in the biological sciences.

Mammalian skull structure is notably diverse; however at a basic level the jaw mechanism is remarkably similar, if not essentially the same, in the majority of mammals. Using simple models that are compared with real animals at every step, this book examines the basic structural features of the mammalian jaw mechanism from a mechanical point of view. It explores how the mechanical constraints placed on the jaw have contributed to the evolution of an efficient basic structure, used by many mammals, which precludes mechanical difficulties and uses a minimum amount of bone tissue. Throughout the book the emphasis is on conceptual understanding, with explanations linked together to form a complete story that can be applied to both fossil and extant mammals. Summarising over forty years of research from one of the leading pioneers in 3D jaw mechanics, this is a must-have for anyone interested in mammalian jaw morphology.

This volume offers a comprehensive history of the Mount Desert Island Biological Laboratory (MDIBL), one of the major marine laboratories in the United States and a leader in using marine organisms to study fundamental physiological concepts. Beginning with its founding as the Harpswell Laboratory of Tufts University in 1898, David H. Evans follows its evolution from a teaching facility to a research center for distinguished renal and epithelial physiologists. He also describes how it became the site of major advances in cytokinesis, regeneration, cardiac and vascular physiology, hepatic physiology, endocrinology and toxicology, as well as studies of the comparative physiology of marine organisms. Fundamental physiological concepts in the context of the discoveries made at the MDIBL are explained and the social and administrative history of this renowned facility is described.

Pursuing the questions of how we learn and how memory is made, Edward Kosower introduces a novel and rich approach to connecting molecular properties with the biological properties that enable us to write and read, to create culture and ethics, and to think. Here he examines what happens within a single cell in reaction to external stimuli, and shows the parallels between single cell and multicellular responses. To address the problem of "learning," Kosower explains the molecular mechanisms of responses to input from taste, olfactory, and visual receptors. He then shows how these and other processes serve as the basis for memory. This study covers such signals for the molecular process of learning as pheromones (the molecular signals mediating behavior), light (activates the G-protein receptor, rhodopsin), and acetylcholine (opens the nicotinic acetylcholine receptor). Kosower's discussion of the structure and function of these complex molecules has direct implications for such areas as molecular neurobiology, bioorganic chemistry, and drug design, in elucidating approaches to the structure of drug targets. Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The study of animal communication has led to significant progress in our general understanding of motor and sensory systems, evolution, and speciation. However, one often neglected aspect is that signal exchange in every modality is constrained by noise, be it in the transmission channel or in the nervous system. This book analyses whether and how animals can cope with such constraints, and explores the implications that noise has for our understanding of animal communication. It is written by leading biologists working on different taxa including insects, fish, amphibians, lizards, birds, and mammals. In addition to this broad taxonomic approach, the chapters also cover a wide array of research disciplines: from the mechanisms of signal production and perception, to the behavioural ecology of signalling, the evolution of animal communication, and conservation issues. This volume promotes the integration of the knowledge gained by the diverse approaches to the study of animal communication and, at the same time, highlights particularly interesting fields of current and future research.
