A thorough understanding of the form, function, and design of animals is essential to any working biologist's knowledge. In the author's view, however, this fast-growing field of study can be made much more exciting and accessible with a hands-on, practical approach. This view is the basis for A Practical Guide to Vertebrate Mechanics. This text can be considered an engineering book for biologists. The emphasis is on vertebrates, and each topic begins with a discussion of the underlying principles, followed immediately by practical experiments and laboratory exercises. The author begins with a refresher on scaling and measurement. This is followed by three chapters on the mechanical properties of materials--investigating elasticity, the strength of materials, and how things break. This leads the discussion to animal materials--bones, joints, muscles--which serve to illustrate principles of structure and load, lubrication, physiology, metabolism, and stamina. Finally, the systems are put in motion, as we discuss terrestrial locomotion, flight, and swimming. What sets this book apart from others on functional anatomy is the emphasis on practical work. Many of the experiments are simple to conduct. Detailed instructions for setting up the experiments are given in an appendix, and sample results are included to guide the student. A Practical Guide to Vertebrate Mechanics will form an important part of undergraduate and beginning graduate courses for zoology, anatomy, biomechanics, and paleontology students.

Teeming with weird and wonderful life--giant clams and mussels, tubeworms, "eyeless" shrimp, and bacteria that survive on sulfur--deep-sea hot-water springs are found along rifts where sea-floor spreading occurs. The theory of plate tectonics predicted the existence of these hydrothermal vents, but they were discovered only in 1977. Since then the sites have attracted teams of scientists seeking to understand how life can thrive in what would seem to be intolerable or extreme conditions of temperature and fluid chemistry. Some suspect that these vents even hold the key to understanding the very origins of life. Here a leading expert provides the first authoritative and comprehensive account of this research in a book intended for students, professionals, and general readers. Cindy Lee Van Dover, an ecologist, brings nearly two decades of experience and a lively writing style to the text, which is further enhanced by two hundred illustrations, including photographs of vent communities taken in situ.

The book begins by explaining what is known about hydrothermal systems in terms of their deep-sea environment and their geological and chemical makeup. The coverage of microbial ecology includes a chapter on symbiosis. Symbiotic relationships are further developed in a section on physiological ecology, which includes discussions of adaptations to sulfide, thermal tolerances, and sensory adaptations. Separate chapters are devoted to trophic relationships and reproductive ecology. A chapter on community dynamics reveals what has been learned about the ways in which vent communities become established and why they persist, while a chapter on evolution and biogeography examines patterns of species diversity and evolutionary relationships within chemosynthetic ecosystems.

Cognate communities such as seeps and whale skeletons come under scrutiny for their ability to support microbial and invertebrate communities that are ecologically and evolutionarily related to hydrothermal faunas. The book concludes by exploring the possibility that life originated at hydrothermal vents, a hypothesis that has had tremendous impact on our ideas about the potential for life on other planets or planetary bodies in our solar system.

First published in 1981, this book is about how the brain controls the behaviour of lower vertebrates. It concentrates on teleosts and amphibians as these are the classes about which most is known. The literature dealing with mammalian brain mechanisms of behaviour is extensive and this book starts to fill the gaps in our knowledge of vertebrate brain behaviour so that the multidisciplinary, comparative approach will be better understood. The text deals with selected topics from five major areas of interest, commencing with the evolution of lower vertebrate brain structure in relation to function. Subsequent sections look at the way sensory information is processed, how sleep, arousal and wakefulness and the level of attention and appetite in lower vertebrates are studies and, finally, how experience may modify the behaviour of these animals. The book combines an introduction to comparative neurothology with specialised topics in which advances have been made. The book will interest students and research workers in neurobiology and animal behaviour.

Habitat loss and degradation are currently the main anthropogenic causes of species extinctions. The root cause is human overpopulation. This unique volume provides, for the very first time, a comprehensive overview of all threatened and recently extinct mammals, birds, reptiles, amphibians, and fishes within the context of their locations and habitats. The approach takes a systematic examination of each biogeographic realm and region of the world, both terrestrial and marine, but with a particular emphasis on geographic features such as mountains, islands, and coral reefs. It reveals patterns useful in biodiversity conservation, helps to put it all into perspective, and ultimately serves as both a baseline from which to compare subsequent developments as well as a standardization of the way threatened species are studied.

The student of biological science in his final years as an undergraduate and his first years as a graduate is expected to gain some familiarity with current research at the frontiers of his discipline. New research work is published in a perplexing diversity of publications and is inevitably concerned with the minutiae of the subject. The sheer number of research journals and papers also causes confusion and difficulties of assimilation. Review articles usually presuppose a back ground knowledge of the field and are inevitably rather restricted in scope. There is thus a need for short but authoritative introductions to those areas of modern biological research which are either not dealt with in standard introductory textbooks or are not dealt with in suffi cient detail to enable the student to go on from them to read scholarly reviews with profit. This series of books is designed to satisfy this need. The authors have been asked to produce a brief outline of their subject assuming that their readers will have read and remembered much of a standard introductory textbook on biology. This outline then sets out to provide by building on this basis, the conceptual framework within which modern research work is progressing and aims to give the reader an indication of the problems, both conceptual and practical, which must be overcome if progress is to be maintained."

In recent years a new field of study has arisen called developmental biology. The term developmental biology is really a new name for embryology; it is, however, used to denote the molecular approach to the study of developing systems. In this book we have tried wherever possible to blend the older information of classical embryology and in particular organogeny with the newer concepts of developmental biology. The original intention was to cover all the tissues of the body in this book. However, it soon became obvious that it was not possible to do this within one volume. Therefore we decided to have two general chapters, one on the basic concepts of cellular development and an other on the ageing of cells (this being considered part of the normal growth process). In addition to these two general chapters we have included chapters on some of the major tissues. These were chosen not just to illustrate the points made in the general chapters but because there is enough information available on the development of these tissues for the expert in that field to present a good, readable account. It is hoped that at a later date when more information is available, we will be able to extend this work, probably as several volumes, and to include the other tissues of the body which are not dealt with in this volume.

When Charles Darwin first proposed Sexual Selection Theory, he suggested two mechanisms: competition among males and choice by females. Although their importance is long established and extremely well understood, their mirror images have remained largely underappreciated; males also choose, and females also compete. The combination of male mate choice (MMC) and female competition (FC) may be one of the most overlooked yet important and intriguing phenomena in modern sexual selection theory. This novel text reviews our current understanding of MMC and FC, highlighting the important connections between them. It places both concepts in the context of related fields such as female choice, mating systems, and sexual selection theory more broadly. A truly holistic approach is provided which takes all the relevant elements into consideration, especially the relative roles of MMC and FC, female ornamentation, their evolutionary consequences, and their genetic basis. Considering male mate choice and female competition in this way as effectively two sides of the same coin creates a powerful paradigm for a more complete understanding of sexual selection. Male Choice, Female Competition, and Female Ornaments in Sexual Selection is suitable for both graduate students and researchers interested in sexual selection from an evolutionary, psychological, and anthropological perspective. It will also appeal to a broader audience of behavioural ecologists and evolutionary psychologists.

The standard electrocardiogram (ECG) is an indispensable, safe, and inexpensive test to assess dogs and cats with heart disease. This bestselling user-friendly book discusses the principles of electrocardiography, then systematically explores the evaluation of the ECG, including determination of heart rate, measurement of intervals, derivation of mean electrical axis, and criteria for atrial/ventricular enlargement or hypertrophy. At the core of this book is an extensive series of ECG cases for the reader to work through: practice makes perfect. New to this edition: Instructions on how to obtain an ECG A new chapter on the treatment of the most common clinically important ECG arrhythmias A second new chapter on 24-hour ECG (Holter) monitoring A handy one-page reference guide of important ECG values and diagrams, which can be downloaded from the book's webpage for easy reference 15 new ECG cases have been added to the original 46 cases, with a selection of advanced cases geared toward readers craving more challenging topics such as electrical cardioversion and pacemaker function. This updated edition will further aid veterinarians in their quest to better interpret the ECG. It provides information in an appealing, accessible, and easy to use format that fits with the busy lives of veterinary practitioners.

The scientific understanding of arthropod phylogeny and evolution has changed significantly in recent decades. One of the most momentous alterations involved crustaceans, which are not a monophyletc group, but are part of a larger group along with insects: Pancrustacea. The old ideas surrounding crustacean evolution have served scientists well for many years; it is now time to turn toward new research by embracing the results derived from investigations conducted largely within this century. For example, new definitions have arisen from sources across several fields of study, and Frederick R. Schram and Stefan Koenemann have created a book that explores paleobiodiversity and the diversity of modern body plans. Developments within ontogenetic studies continue to generate remarkable insights into crustaceomorph evolution in regard to patterns of embryology and a revolution in the application of development genetics. Phylogeny techniques of analysis and new sources of data derived from molecular sequencing and genetic studies have forced scientists to consider new hypotheses concerning the interrelationships of all the pancrustaceans, both the crustaceomorphs and Hexapoda. Yet, some fossil groups still remain enigmatic (Thylacocephala). Despite this, research into fossils (even if incompletely understood) fills in gaps of our knowledge of paleobiodiversity, and it's useful for many things, including analyzing the origin and early evolution of Hexapoda. Evolution and Phylogeny of Pancrustacea demonstrates the use of multiple alternative hypotheses and other techniques through the well-executed presentation of diverse data sources involving Pancrustacea. Readers are left with clues to great mysteries, including the possible pathways of evolution within marine arthropods.

Chordates comprise lampreys, hagfishes, jawed fishes, and tetrapods, plus a variety of more unfamiliar and crucially important non-vertebrate animal lineages, such as lancelets and sea squirts. This will be the first book to synthesize, summarize, and provide high-quality illustrations to show what is known of the configuration, development, homology, and evolution of the muscles of all major extant chordate groups. Muscles as different as those used to open the siphons of sea squirts and for human facial communication will be compared, and their evolutionary links will be explained. Another unique feature of the book is that it covers, illustrates, and provides detailed evolutionary tables for each and every muscle of the head, neck and of all paired and median appendages of extant vertebrates. Key Selling Features: Has more than 200 high-quality anatomical illustrations, including evolutionary trees that summarize the origin and evolution of all major muscle groups of chordates Includes data on the muscles of the head and neck and on the pectoral, pelvic, anal, dorsal, and caudal appendages of all extant vertebrate taxa Examines experimental observations from evolutionary developmental biology studies of chordate muscle development, allowing to evolutionarily link the muscles of vertebrates with those of other chordates Discusses broader developmental and evolutionary issues and their implications for macroevolution, such as the links between phylogeny and ontogeny, homology and serial homology, normal and abnormal development, the evolution, variations, and birth defects of humans, and medicine.

This book appeals to population biologists, evolutionary biologists and social scientists. It is a key resource for on-the-ground managers and research scientists developing harvesting applications. As the book's contributors explain: "Making decisions that are robust to uncertainty...is a paradigm shift with a lot of potential to improve outcomes for fish and wildlife populations." -Andrew Tyre and Brigitte Tenhumberg "Temporal shifts in system states...must somehow be anticipated and dealt with to derive harvest policies that remain optimal in the long term." -Michael Conroy "Proactive, effective management of sportspersons...will be essential in the new paradigm of harvest management." -Matthew Gruntorad and Christopher Chizinski

This volume examines cells set aside during development for use later in ontogeny or in adult life. There is no single term for such cells. The cells explored fall within several major categories - stem cells, set-aside cells (in echinoderm larvae), imaginal discs in insects such as Drosophila, meristems (plants), blastemata (regeneration in amphibians), neoblasts (regeneration in planarians). The book compares and contrasts these cell types and the environments (niches) in which they operate with the aim of unravelling any relationships between them, between their activation in development, and in their evolution. Key Features Explores the nature of deferred-use cells in evolutionary and developmental context. Reviews the mechanisms of development of set-aside cells, such as stem cells, meristems, and imaginal discs. Provides phylogenetic overview of different types of deferred-use cells. Compares and contrasts different theories on the origin of deferred-use cells. Related Titles Calegari, F. & C. Waskow, eds.

Cooperative breeders are species in which individuals beyond a pair assist in the production of young in a single brood or litter. Although relatively rare, cooperative breeding is widespread taxonomically and continues to pose challenges to our understanding of the evolution of cooperation and altruistic behavior. Bringing together long-term studies of cooperatively breeding birds, mammals, and fish, this volume provides a synthesis of current studies in the field. The chapters are organised by individual studies of particular species or (in the case of mole-rats) two closely related cooperatively breeding species. Each focuses not only on describing behavior and ecology but also on testing evolutionary hypotheses for the form and function of the diverse and extraordinary cooperative breeding lifestyles that have been discovered. This unique and comprehensive text will be of interest to graduate students and researchers of behavioral ecology and the evolution of cooperation.

As sequel to Aquatic Animal Nutrition - A Mechanistic Perspective from Individuals to Generations, the present treatise on organic macro- and micronutrients continues the unique cross fertilization of aquatic ecology/ecophysiology and aquaculture. This treatise considers proteins and their constituents, carbohydrates from mono- to polysaccharides, fatty acids from free acids to fat, and waxes. It becomes obvious that these organic nutrients are more than only simple fuel for the metabolism of animals; rather, their constituents have messenger and controlling function for the actual consuming individual and even for succeeding generations. This aspect will become particularly clear by putting the organisms under consideration back into their ecosystem with their interrelationships and interdependencies. Furthermore, micronutrients, such as vitamins and nucleotides as well as exogenous enzymes, are in the focus of this volume with known and still-to-be-discovered controlling physiological and biomolecular functions. Aquatic Animal Nutrition - Organic Macro and Micro Nutrients addresses se veral gaps in nutritional research and practice. One major gap is the lack of com mon research standards and protocols for nutritional studies so that virtually incomparable approaches have to be compared. This applies also to the studied animals, since most approaches disregard intraspecific variabilities and the existence of epimutations in farmed individuals. Furthermore, recalling the Mechanistic Perspective from Individuals to Generations, dietary benefits and deficiencies have effects on succeeding generations. In most studies, this long-term and sustainable aspect is overruled by pure short-term production aspects. By comparing nutritional behavior and success of fishes and invertebrates, Aqua tic Animal Nutrition points out different metabolic pathways in these animal groups and discusses how, for instance, fishes would benefit when having some successful metabolic pathway of invertebrates. Application of novel ge ne tic techniques will help turn this vision into reality. However, a widely missing link in the current nutritional research is epigenetics regarding transgenerational heritages of acquired morphological and physiological properties. To in crease public acceptance, nutritional optimization of farmed animals based on this mechanism, rather than genetical engineering, appears promising.

Cognitive neuroscience has been the most productive, and arguably the most exciting area of growth in psychology and neuroscience over recent years, with remarkable insights into the brain mechanisms of cognitive abilities being gained from studies of both animals and humans. Johan Bolhuis has brought together a stellar list of contributors, including, amongst others, Patrick Bateson, Lawrence Weiskrantz, Robert Hinde, Eric Kandel, Mark Johnson, and James McGaugh to provide a truly authoritative and comprehensive overview of our current knowledge of the essential neural mechanisms of perception, learning, and memory. Written to be accessible to advanced undergraduates, and postgraduates, the book describes the latest advances in the most important fields of cognitive neuroscience. Brain, Perception, Memory will be an invaluable reference work and textbook for advanced students and researchers in cognitive psychology, neuroscience, and animal behaviour.

This book serves as a comprehensive yet concise reference guide reviewing the latest knowledge on bacterial, viral, fungal and parasitic infectious diseases of old world dromedary camels. Pathogen etiology, clinical manifestations and diagnostic techniques are provided for each pathogen and disease prevention and treatment strategies are discussed. Despite a steady increase in camel husbandry worldwide, the pathologies of camel diseases are still relatively under investigated in comparison to other livestock and companion animals. With an ongoing worldwide prevalence increase, infectious diseases are a constant threat to animal and human health. In recent years dromedary camels have become a focus of increasing public health interest since they have been considered the direct source of zoonotic transmission of MERS-CoV to humans. Along these lines, the book covers topics related to zoonotic infections associated with camels. This book offers a valuable source of information for veterinary clinicians, researchers, graduate students, veterinary technicians and interested laymen.

Males and females often differ in developmental patterns, adult morphology, ecology and behaviour, and in many mammals males are often larger. Size dimorphism results in divergent nutritional and energetic requirements or reproductive strategies by the sexes, which in turn sometimes causes them to select different forage, use different habitats, and express differing social affinities. Such divergent life-styles often lead males and females to live large parts of their lives separately. Sexual segregation is widespread in animals. Males and females may share the same habitat, but at different times, for example, or they might use different habitats entirely. Why did sexual segregation evolve and what factors contribute to it? Sexual Segregation in Vertebrates explores these questions by looking at a wide range of vertebrates and is aimed as a synthesis of our current understanding and a guide for future research.

This book is useful for anyone interested in the basic structural and functional characteristics of the digestive system and how these vary among vertebrate groups and species. It discusses all of the major aspects of nutrition, anatomy and physiology in all of the major groups of vertebrates. It contains numerous figures and tables to aid in their comparison, including many illustrations of gastrointestinal tracts of vertebrates prepared so as to allow for direct comparison. The terminology of scientific specialties and sub-specialties is defined and animals are referred to by both their common and scientific names. Relationships between digestive strategies and the diet and environment are discussed throughout the text, and brought together in a chapter on the evolution of the digestive system. The final chapter offers a brief summary of the major concepts and suggests future directions for research.

Hans Kruuk, a life-long naturalist, tells the fascinating story of carnivores and humans' intricate relationships with them. The book is illustrated with specially commissioned drawings, and deals not only with the wild beauty of carnivores and their conservation, but also with the topics of furs and medicine, man-eaters and sheep-killers. Kruuk explains in simple terms the role of carnivores in nature, how they impact human life, art and literature, and how we instinctively respond to them and why.
