The emphasis in this volume is on the structure and functional design of the integument. The book starts with a brief introduction to some basic principles of physics (mechanics) including Newton’s Three Laws of Motion. These principles are subsequently used to interpret the problems animals encounter in motion. It is in only the last 40 or so years that we have begun to understand how important a role the integument plays in the locomotion of many marine vertebrates. This involves the crossed-fiber architecture, which was first discovered in a classic study on nemertean worms. As a design principle we see that the crossed-fiber architecture is ubiquitous in nature. Research on some of the most dynamic marine vertebrates of the oceans – tuna, dolphins and sharks, and the extinct Jurassic ichthyosaurs – shows precisely how the crossed-fiber architecture contributes to high-speed swimming and (in lamnid sharks) may even aid in energy conservation. However, this design principle is not restricted to animals in the marine biota but is also found as far afield as the dinosaurs and, most recently, has been revealed as a major part of the microstructure of the most complex derivative of the integument, the feather. We see that a variety of phylogenetically diverse vertebrates take to the air by using skin flaps to glide from tree to tree or to the ground, and present detailed descriptions of innovations developed in pursuit of improved gliding capabilities in both extinct and modern day gliders. But the vertebrate integument had even greater things in store, namely true or flapping flight. Pterosaurs were the first vertebrates to use the integument as a membrane in true flapping flight and these interesting extinct animals are discussed on the basis of past and cutting-edge research , most intriguingly with respect to the structure of the flight membrane. Bats, the only mammals that fly, also employ integumental flight membranes. Classic research on bat flight is reviewed and supplemented with the latest research, which shows the complexities of the wing beat cycle to be significantly different from that of birds, as revealed by particle image velocimetry. The book’s largest chapter is devoted to birds, given that they make up nearly half of the over 22,000 species of tetrapods. The flight apparatus of birds is unique in nature and is described in great detail, with innovative research highlighting the complexity of the flight structures, bird flight patterns, and behavior in a variety of species. This is complimented by new research on the brains of birds, which shows that they are more complex than previously thought. The feather made bird flight possible, and was itself made possible by β-keratin, contributing to what may be a unique biomechanical microstructure in nature, a topic discussed in some depth. A highly polarized subject concerns the origin of birds and of the feather. Alleged fossilized protofeathers (primal simple feathers) are considered on the basis of histological and taphonomic investigative studies in Chapter 6. Finally, in Chapter 7 we discuss the controversies associated with this field of research. Professor Theagarten Lingham-Soliar works at the Nelson Mandela Metropolitan University, Port Elizabeth and is an Honorary Professor of Life Sciences at the University of KwaZulu-Natal.
This book summarizes the key adaptations enabling extremophile fishes to survive under harsh environmental conditions. It reviews the most recent research on acidic, Antarctic, cave, desert, hypersaline, hypoxic, temporary, and fast-flowing habitats, as well as naturally and anthropogenically toxic waters, while pointing out generalities that are evident across different study systems. Knowledge of the different adaptations that allow fish to cope with stressful environmental conditions furthers our understanding of basic physiological, ecological, and evolutionary principles. In several cases, evidence is provided for how the adaptation to extreme environments promotes the emergence of new species. Furthermore, a link is made to conservation biology, and how human activities have exacerbated existing extreme environments and created new ones. The book concludes with a discussion of major open questions in our understanding of the ecology and evolution of life in extreme environments.
The book "Parasitic Zoonoses" emphasizes a veterinary and public health perspective of zoonotic parasites. This book is suitable for higher undergraduate and graduate students of zoonoses and public health, veterinary parasitology, parasite epidemiology; public health workers; public health veterinarians; field veterinarians, medical professionals and all others interested in the subject. More than 15 protozoa and 50 other parasitic diseases are zoonotic in nature and all these diseases have been discussed in detail. The first chapter is concerned with classification of zoonotic parasites, food borne, vector borne and occupation related zoonotic parasites. The remaining chapters cover etiology, epidemiology, life cycle, transmission, clinical signs, diagnosis, prevention and control of zoonotic parasites. The text is illustrated with a large number of coloured figures. An alphabetical bibliography for every disease has also been included so that readers have access to further information.
This book covers advances made since the 2004 Springer volume "Polarized Light in Animal Vision" edited by Horvath and Varju, but also provides reviews and synopses of some areas. Part I examines polarization sensitivity across many animal taxa including vertebrates and invertebrates and details both terrestrial and aquatic life. Part II is devoted to the description of polarized light in nature and explores how the physics of light must be taken into account when understanding how polarized light is detected by the visual system. This includes underwater polarization due to scattering; polarization patterns reflected from freshwater bodies; polarization characteristics of forest canopies; normal and anomalous polarization patterns of the skies; skylight polarization transmitted through Snell's window and both linearly and circularly polarized signals produced by terrestrial and aquatic animals. This Part also examines polarized "light pollution" induced by anthropogenic factors such as reflection off asphalt surfaces, glass panes, car bodies, and other man-made structures that are now known to form ecological traps for polarotactic insects. Part III surveys some of the practical applications of polarization vision including polarization-based traps for biting insects, ground-based polarimetric cloud detectors and an historical examination of the navigational abilities of Viking seafarers using the sky polarization compass. The deterrent qualities of ungulate pelage to polarization-sensitive biting insects is also examined in this section.
Research over the years has demonstrated that free radicals mediated oxidative stress lies at the helm of almost all patho-physiological phenomena. These findings emphasize on the need to understand the underlying molecular mechanism(s) and their critical role in the pathogenesis. This book aims to focus on these areas to provide readers a comprehensive outlook about the major redox sensitive pathways and networks involved in various disease conditions. In the first chapter of the book, basic information about the oxidative stress, its generation, its biomarkers and its role in body are discussed. In the next three chapters, the role of oxidative stress in various pathologies ranging from neurological disorders, to cardiovascular diseases, cancers, metabolic diseases and ageing have been described. Chapter 5 cumulatively describes the most important molecular signaling pathways that are affected by reactive oxygen species (ROS). These are the mechanisms which are common denominators in various pathological states. In the next part of the book, various antioxidant strategies to target and mitigate ROS have been discussed with details on the mechanisms. Selenium, being the research focus and interest of the authors for years, the role of selenium as an antioxidant as part of selenoproteins has been included in the book. Finally, the book culminates with authors’ perspective on the future of the redox biology field. Throughout the book, efforts have been made to use simplified language and suitable figures for ease to understand the contents. Although the authors have tried to touch on all the different aspects of oxidative stress in detail, the fact that it is a continuously growing field with updates coming every day, there might be some areas which might not be described in depth. This book is designed for students, young scientists to get acquainted with the redox biology. Overall, this book is a reference to understand the redox regulation of cellular signaling pathways involved in pathogenesis.
Vertebrate Endocrinology, Sixth Edition, provides a comprehensive, up-to-date treatment of the endocrine system for college and university students as well as researchers. This book is logically arranged, easily comprehended, and well-illustrated. It covers traditional hormone-based systems and introduces all forms of chemical communication, their implications for the health of humans, domesticated, and wild vertebrates. Written by two experts who have completed extensive research in comparative vertebrate endocrinology with an emphasis on natural and anthropogenic environmental factors influencing endocrine systems. Collectively, the authors have taught courses in endocrinology at the undergraduate and graduate level for more than 60 years. After first publishing in 1985, Vertebrate Endocrinology, Sixth Edition, continues to serve as an important resource for graduate students and advanced undergraduates in the biological sciences, animal sciences, and veterinary sciences. Endocrine researchers will also benefit from the book's relevance in the areas of comparative, veterinary, and mammalian endocrinology.
This book offers a new explanation for the development of flight in mammals and offers detailed morphological descriptions of mammals with flapping flight. The skeletomuscular apparatus of the shoulder girdle and forelimbs of tree shrews, flying lemurs and bats is described in detail. Special attention is paid to the recognition of peculiar features of the skeleton and joints. For the basic locomotor patterns of flying lemurs and bats, the kinematic models of the shoulder girdle elements are developed. The most important locomotor postures of these animals are analyzed by means of statics. The key structural characters of the shoulder girdle and forelimbs of flying lemurs and bats, the formation of which provided transition of mammals from terrestrial locomotion to gliding and then, to flapping flight, are recognized. The concept is proposed that preadaptations preceding the acquisition of flapping flight could have come from widely sprawled forelimb posture while gliding from tree to tree and running up the thick trunks. It is shown that flying lemur is an adequate morphofunctional model for an ancestral stage of bats. The evolutionary ecomorphological scenario describing probable transformational stages of typical parasagittal limbs of chiropteran ancestors into wings is developed.
This book discusses oxidative stress and hormesis from the perspective of an evolutionary ecologist or physiologist. In the first of ten chapters, general historical information, definitions, and background of research on oxidative stress physiology, hormesis, and life history are provided. Chapters 2-10 highlight the different solutions that organisms have evolved to cope with the oxidative threats posed by their environments and lifestyles. The author illustrates how oxidative stress and hormesis have shaped diversity in organism life-histories, behavioral profiles, morphological phenotypes, and aging mechanisms. The book offers fascinating insights into how organisms work and how they evolve to sustain their physiological functions under a vast array of environmental conditions.
The Micro-Tomographic Atlas of the Mouse Skeleton provides a unique systematic description of all calcified components of the mouse. It includes about 200 high resolution, two and three dimensional m CT images of the exterior and interiors of all bones and joints. In addition, the spatial relationship of bones within complex skeletal units is also described. The images are accompanied by detailed explanatory text, thus highlighting special features and newly reported structures. The Atlas fulfils an emerging need for a comprehensive reference to assist both trained and in-training researchers.
Darwinian medicine looks at the ecological and evolutionary roots of disease. A disease is an interaction between a genome and its biotic or abiotic environment and therefore a disease is essentially an ecological process. Good understanding of ecology and a Darwinian way of thinking can give us novel and useful perspectives on health and disease. If we understand the disease process better, we can certainly prevent, control as well as treat diseases in a better way. Although the thought that the origins of obesity and type 2 diabetes (T2D) might lie in our hunter gatherer adaptations is not new, research over the last decade makes us rethink many of the classical concepts. Brain and behavior is increasingly being recognized as central to all the endocrine, metabolic and immunological changes that earmark type 2 diabetes and other metabolic syndrome disorders. A major change in paradigm appears to be on the horizon and the proposed book intends to speed up the paradigm shift by raising important questions, pointing out flaws and inadequacies in the prevalent paradigm and stimulating radical rethinking which would redirect and refine the line of research as well as bring some fundamental changes in drug discovery and clinical practice.
E.F.F. Chladni's experiments and observations with sound and vibrations profoundly influenced the development of the field of Acoustics. The famous Chladni diagrams along with other observations are contained in Die Akustik, published in German in 1802 and Traite d'Acoustique, a greatly expanded version, published in French in 1809. This is the first comprehensive translation of the expanded French version of Traite d'Acoustique, using the 1802 German publication for reference and clarification. The translation was undertaken by Robert T. Beyer, PhD (1920-2008), noted acoustician, Professor of Physics at Brown University, and Gold Medal recipient of the Acoustical Society of America. Along with many other projects completed over the course of his career, Dr. Beyer translated Von Neumann's seminal work, Mathematical Foundations of Quantum Mechanics from the original German, spent 30 years translating Russian physics treatises and journals, served as editor of the English translation of the Soviet Journal of Experimental and Theoretical Physics, and also authored Sounds of our Times: Two Hundred Years of Acoustics.
Entomology as a science of inter-depended branches like molecular entomology, insect biotechnology, has made rapid progress. This also implies that there is an urgent need to manage the available resources. In the past five decades, entomology has taken giant steps ahead. The aim of this work is to integrate perspectives across molecular and biochemistry, physiology, reproduction, developmental biology, molecular evolution, genetics and RNAi applications. This century is proclaimed as the Era of Biotechnology and it consists of all types of Mol-Bio-Gen applications, which is an essential component for a thorough understanding of the insect biology. The aim of this work is to provide the comprehensive review of recent research from various geographic areas around the world and contributing authors that are recognized experts in their respective field of Genomic entomology. This Volume emphasizes upon the need for and relevance of studying molecular aspects of entomology in Universities, Agricultural Universities and other centers of molecular research. It will also serve as a landmark source for Insect advance science technology.
A history of the agricultural sciences in Nazi Germany is presented in this book.

The book includes core concepts in anatomy and physiology in human and animal models, which are key to understanding comparative medicine and to making contributions to research in this area. While writing this book, the authors were in constant interdisciplinary dialogue. They aim to contribute to improvements in quality of life for human and animal patients.
Channels and transporters are multi-functional proteins that mediate substrate transport and signal transmission and simultaneously act as regulators for other proteins and biosensors for environmental materials. Patch clamping is an epoch-making technique that allows researchers to perform real-time measurements of electrogenic channel/transporter functions at the single/multiple molecular level. This book describes not only the conventional patch clamp techniques but also their newly developed variations or applications, such as perforated patch, slice patch, blind patch, in vivo patch, imaging patch, smart patch, and automated patch clamping. These patch clamp techniques are now essential and are extensively used across the life sciences and in related industries. With plain and practical descriptions of patch clamping and how to carry it out, especially for beginners, the book also shows how widely and exquisitely the patch clamp techniques can be applied by expert electrophysiologists. This work serves as a useful guide for young researchers and students in training and laboratory courses as well as for senior researchers who wish to extend their repertoire of techniques.

It provides a timely overview of the current progress being made by Italian researchers and is of great value to anyone interested in all fields of veterinary science, both theoretical and applied, ranging from animal health and care to animal production and food hygiene.
This SpringerBrief provides a concise summary on the chemistry and function of murine pheromones in reproduction. It discusses mechanisms of action as well as the applicability of these mechanisms to humans. The image of pheromones is usually some invisible mysterious chemicals that make people attracted to the opposite sex. However, pheromones have many functions and one that perhaps is not well known yet is that they affect the reproductive status of others. Males' pheromones stimulate females' reproductive status and vice versa. This book will present studies on male mice which is rarely covered and will also discuss trans-generational influences of pheromones. The book addresses Professors, researchers and students working in animal neurochemistry, chemical signaling and reproductive medicine.
With the availability of high speed computers and advances in computational techniques, the application of mathematical modeling to biological systems is expanding. This comprehensive and richly illustrated volume provides up-to-date, wide-ranging material on the mathematical modeling of kidney physiology, including clinical data analysis and practice exercises. Basic concepts and modeling techniques introduced in this volume can be applied to other areas (or organs) of physiology. The models presented describe the main homeostatic functions performed by the kidney, including blood filtration, excretion of water and salt, maintenance of electrolyte balance and regulation of blood pressure. Each chapter includes an introduction to the basic relevant physiology, a derivation of the essential conservation equations and then a discussion of a series of mathematical models, with increasing level of complexity. This volume will be of interest to biological and mathematical scientists, as well as physiologists and nephrologists, who would like an introduction to mathematical techniques that can be applied to renal transport and function. The material is written for students who have had college-level calculus, but can be used in modeling courses in applied mathematics at all levels through early graduate courses.
This book provides developmental data regarding piglets (with a focus on the gastrointestinal tract), data related to amino acid metabolism in pigs, data related to nutritional and physiological functions of amino acids in pigs, nutritional requirements for amino acids in pigs, signaling roles of amino acids, methodological aspects in amino acid research and the pig model for studying amino acid-related human diseases.
Latent knowledge in the field of pig reproduction is vast but scattered, making it difficult to take in all information at a glance. Moreover, nascent branches in biotechnology cannot grow if deprived of roots. The book Boar Reproduction: Fundamentals and New Biotechnological Trends links the past, the present and the emerging scientific research fields on reproductive biotechnology, offering a rigorous but easy to follow compilation of topics, from "old favorites" to the latest advances. The book is organized in three parts. The chapters of the first and second part cover various biological aspects of boar spermatozoa within the male, and within the female environments, respectively. The most common laboratory and artificial insemination techniques are discussed in the third part. As an additional feature, some chapters focus on the basis of a technology transfer to bring research expertise from basic science to the market, making the information provided in this book suitable for academic, research and other professional applications.
This second volume in the Natural History of the Crustacea series examines how crustaceans-the different body shapes and adaptations of which are described in volume 1-make a living in the wide range of environments they inhabit, and how they exploit food sources. The contributions in the volume give synthetic overviews of particular lifestyles and feeding mechanisms, and offer a fresh look at crustacean life styles through the technological tools that have been applied to recent crustacean research. These include SEM (scanning electron microscope) techniques, micro-optics, and long-term video recordings that have been used for a variety of behavioral studies. The audience will include not only crustacean biologists but evolutionary ecologists who want to understand the diversification of particular life styles, ecologists who follow the succession of communities, biogeochemists who estimate the role of crustaceans in geochemical fluxes, and biologists with a general interest in crustaceans.
Leaping Ahead: Advances in Prosimian Biology presents a summary of the state of prosimian biology as we move into the second decade of the 21st century. The book covers a wide range of topics, from assessments of diversity and evolutionary scenarios, through ecophysiology, cognition, behavioral and sensory ecology, to the conservation and survival prospects of this extraordinary and diverse group of mammals. The collection was inspired by an international conference in Ithala, KwaZulu-Natal, South Africa in 2007, where prosimian biologists gathered from Canada, Finland, France, Germany, India, Italy, Japan, Madagascar, South Africa, Tanzania, the United Kingdom, and the United States of America. The meeting reverberated with the passion prosimian researchers feel for their study subjects and with their deep concern for the future of prosimians in the face of ongoing habitat destruction and the burgeoning threat of bushmeat hunting. Chapters for this volume were contributed by researchers from across the globe; they attest to the diversity, vibrancy and rapid growth of prosimian biology, and to the intellectual advances that have revolutionized this field in recent years. Since its earliest beginnings, prosimian research and its resultant literature have had a strong francophone component, and researchers in many prosimian habitat countries are more comfortable reading and writing in French rather than English. French summaries of all chapters have been included. The volume is targeted at researchers, both those entering the field and established scientists, who have an interest in the biology of primates and small mammals. It is also aimed at conservation biologists seeking a deeper understanding of the faunas and conservation developments in Africa, Madagascar and Southeast Asia, and anyone who has an interest in discovering the true diversity of our order, the Primates.
Crustacean Nervous Systems and their Control of Behavior is the third volume of the series The Natural History of the Crustacea. This volume is on the functional organization of crustacean nervous systems, and how those nervous systems produce behavior. It complements other volumes on related topics of feeding biology, reproductive biology, endocrine systems, and behavioral ecology. There is a rich history of the study of the neurobiology of crustaceans, going back over 150 years. This has included studies on how their nervous systems allow them to perform behaviors that are adapted to their particular environments, as well as studying them as model organisms to understand basic biomedical principles about neural function, such as sensory transduction and processing, synaptic transmission and integration, neuromodulation, and learning and memory. The volume has three sections that build progressively on each other. The first section is on the basic organizational features of the crustacean nervous system and the principles upon which it is built. The second section is on sensory ecology - the organization of each sensory system and how it is used in intra- and interspecific interactions, within an ecological context. The third section uses case studies of how crustacean nervous systems are organized to perform complex behaviors and interactions, such as walking, escape, social interactions, and memory and learning. Taken together, the 20 chapters synthesize our modern understanding of the neural control of behavior in crustaceans, based on the most recent technologies in physiological recording, molecular biology, and computational science. This volume will be useful to students and researchers as a concise summary of current knowledge of crustacean neuroscience.
Primate Craniofacial Function and Biology is an integrative volume with broad coverage of current research on primate craniofacial biology and function. Topic headings include: the mammalian perspective on primate craniofacial form and function, allometric and comparative morphological studies of primate heads, in vivo research on primate mastication, modeling of the primate masticatory apparatus, primate dental form and function, and palaeoanthropologic studies of primate skulls. Additionally, the volume includes introductory chapters discussing how primatologists study adaptations in primates and a discussion of in vivo approaches for studying primate performance. At present, there are no texts with a similar focus on primate craniofacial biology and no sources that approach this topic from such a wide range of research perspectives. This breadth of research covered by leaders in their respective fields make this volume a unique and innovative contribution to biological anthropology.
The book, entitled "Welfare of farmed fish in present and future production systems", summarises the view of more than 80 experts in the field of fish welfare, collected over a period of more than five years in an international network entitled "Welfare of Fish in European Aquaculture" (Cost action 867), which was sponsored by the COST Office. COST is the acronym for European Cooperation in Science and Technology. During the time of the action a shift became evident in the general perception of fish welfare. It now not only includes variables with very direct effects on growth, and thereby the economy of the farmer, such as disease, water and feed quality, but the term also includes fish preferences and biology-based stimulation measures. This Cost action has contributed to the notion that welfare sets biological criteria for a sustainable production system. We present the reader with an overview of the results obtained, which can help to guide the way towards welfare of farmed fish in present and future production systems. The first chapter gives an overview of the scientific papers that follow. All scientific papers and the first chapter were previously published in Fish Physiology and Biochemistry, vol. 38, number 1, 2012. Given the accruing interest in fish welfare in society, each of these scientific papers should be accessible for stakeholders that are not part of the research community. For that reason each of the scientific papers is preceded by a summary for non-experts. Previously published in Fish Physiology and Biochemistry, vol. 38, number 1, 2012 |
