Nature helps... of course at first itself by developing measures that give bacteria, fungi, plants and animals a chance to be successful in their struggle for life. As a latecomer on Earth, Homo sapiens was gifted with some droplets of the divine spirit of recognition and thus became able to observe, to analyse and recombine skills of other living beings and to use them for his overwhelming career over the last 10,000 years.Of course fungi, plants, animals and even bacteria were primarily used by mankind as food or as lifestyle products such as beer, but soon it became clear that there was much more potential hidden in these organisms and that they could be used for other purposes, too. Extracts of plants and fungi were recognized as powerful remedies, as medicines, as insecticides or acarizides, as repellents against parasites or even as weapons, e.g. when poisonous compounds from frogs or plants were applied to arrowheads. Over the last 110 years the pharmaceutical industry has often simulated nature by analyzing complex organic substances taken from living organisms and then producing by synthesis absolutely pure compounds, which mostly consisted of only one single active substance. These products had the advantage of acting against precisely one target and thus produced fewer possible side effects than the complex plant extracts. However, the more serious side effect was that disease agents could develop resistances to pure medicinal products much more easily. Thus after 70 years of excellent prospects for chemotherapy, some dark clouds appeared and quickly gathered, so that several therapeutic remedies now no longer work. Therefore in many countries - especially in those where the pure chemotherapeutics are too expensive for the poor population - the cry "back to nature" is becoming louder and louder. This has led to an enormous increase of studies that again use natural extracts as remedies in the fight against diseases. The present book summarizes examples of promising aspects in a broad spectrum of applications and shows how extracts derived from bacteria, marine organisms, plants or even animals may help to treat infectious diseases, how such organisms may keep away parasites and pests from the bodies of plants or animals, including humans, and how they can be used directly to aid in diagnosis, promote wound healing and even to help catch criminals. These 15 chapters offer not only basic research on these different fields, but also show how useful and effective products can be developed from research.

This volume of the series Handbook of Zoology deals with the anatomy of the gastrointestinal digestive tract - stomach, small intestine, caecum and colon - in all eutherian orders and suborders. It presents compilations of anatomical studies, as well as an extensive list of references, which makes widely dispersed literature accessible. Introductory sections to orders and suborders give notice to biology, taxonomy, biogeography and food of the respective taxon. It is a characteristic of this book that different sections of the post-oesophageal tract are discussed separately from each other. Informations on form and function of organs of digestion in eutherians are discussed under comparative-anatomical aspects. The variability and diversity of anatomical structures represents the basis of functional differentiations.

There are several books on properties of chitin and associated biomolecules and their biochemical significance. However, the present volume deals with a wide variety of biogeochemical and organic geochemical aspects of this vital macromolecule written by leading authors and experts in the field. Each chapter is carefully peer reviewed and is an updated account of recent research in isotopic, nanostructural, biochemical, microstructural, geochemical, paleontological and experimental aspects of chitin formation, distribution and preservation in the environment and earth history.

The contributed volume puts emphasis on a superior role of water in (bio)systems exposed to a mechanical stimulus. It is well known that water plays an extraordinary role in our life. It feeds mammalian or other organism after distributing over its whole volume to support certain physiological and locomotive (friction-adhesion) processes to mention but two of them, both of extreme relevance. Water content, not only in the mammalian organism but also in other biosystems such as whether those of soil which is equipped with microbiome or the ones pertinent to plants, having their own natural network of water vessels, is always subjected to a force field.The decisive force field applied to the biosystems makes them biomechanically agitated irrespective of whether they are subjected to external or internal force-field conditions. It ought to be noted that the decisive mechanical factor shows up in a close relation with the space-and-time scale in which it is causing certain specific phenomena to occur.The scale problem, emphasizing the range of action of gravitational force, thus the millimeter or bigger force vs. distance scale, is supposed to enter the so-called macroscale approach to water transportation through soil or plants' roots system. It is merely related to a percolation problem, which assumes to properly inspect the random network architecture assigned to the biosystems invoked. The capillarity conditions turn out to be of prior importance, and the porous-medium effect has to be treated, and solved in a fairly approximate way.The deeper the scale is penetrated by a force-exerting and hydrated agent the more non-gravitational force fields manifest. This can be envisaged in terms of the corresponding thermodynamic (non-Newtonian) forces, and the phenomena of interest are mostly attributed to suitable changes of the osmotic pressure. In low Reynolds number conditions, thus in the (sub)micrometer distance-scale zone, they are related with the corresponding viscosity changes of the aqueous, e.g. cytoplasmatic solutions, of semi-diluted and concentrated (but also electrolytic) characteristics. For example, they can be observed in articulating systems of mammals, in their skin, and to some extent, in other living beings, such as lizards, geckos or even insects. Through their articulating devices an external mechanical stimulus is transmitted from macro- to nanoscale, wherein the corresponding osmotic-pressure conditions apply. The content of the proposed work can be distributed twofold. First, the biomechanical mammalian-type (or, similar) systems with extraordinary relevance of water for their functioning will be presented, also including a presentation of water itself as a key physicochemical system/medium. Second, the suitably chosen related systems, mainly of soil and plant addressing provenience, will be examined thoroughly. As a common denominator of all of them, it is proposed to look at their hydrophobic and/or (de)hydration effects, and how do they impact on their basic mechanical (and related, such as chemo-mechanical or piezoelectric, etc.) properties. An additional tacit assumption employed throughout the monograph concerns statistical scalability of the presented biosystems which is equivalent to take for granted a certain similarity between local and global system's properties, mostly those of mechanical nature. The presented work's chapters also focus on biodiversity and ecological aspects in the world of animals and plants, and the related systems. The chapters' contents underscore the bioinspiration as the key landmark of the proposed monograph.

This second volume in the series covers such topics as DNA fingerprinting of fishes, the cytochromes P450 in fish, the molecular biology of bacterial fish diseases, and new insights into the origins of the diversity and distribution of fish antifreeze proteins. The book will be of great value to fisheries scientists, animal biochemists, physiologists and endocrinologists, and aquaculturists. It will provide researchers and students alike with a pertinent information source from theoretical and experimental angles.

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.

Fisheries resources are an important component of natural resources. It is an important source of high-quality animal protein and food for humans, which provides employment, economic benefits and social welfare for people engaged in fishing activities. It also has played an important role in food safety, economic development, and foreign trade. Fisheries resources economics is an important branch of both applied economics and resource economics. Its research object is fishery resources and its economic problems. The economics of fishery resources is to focus on the relationship between the demand for human economic activities and the supply of fishery resources, as well as between fishery resources and its development. This book expounds the reasons for the economic problems of fishery resources and the theoretical principles for solving them, so as to reveal the objective rules of the allocation of fishery resources in different regions and at different times, to coordinate the relationship between the utilization of fishery resources and economic development, and to realize the sustainable development of fishery economy. This book will also provide learning materials for undergraduates, graduate students and practitioners engaged in fishery resources development and scientific management.

The successful previous volume on this topic provided a detailed benchwork manual for the most commonly used animal models of acute neurological injuries including cerebral ischemia, hemorrhage, vasospasm, and traumatic brain and spinal cord injuries. Animal Models of Acute Neurological Injuries II: Injury and Mechanistic Assessments aims to collect chapters on assessing these disorders from cells and molecules to behavior and imaging. These comprehensive assessments are the key for understanding disease mechanisms as well as developing novel therapeutic strategies to ameliorate or even prevent damages to the nervous system. Volume 1 examines general assessments in morphology, physiology, biochemistry and molecular biology, neurobehavior, and neuroimaging, as well as extensive sections on subarachnoid hemorrhage, cerebral vasospasm, and intracerebral hemorrhage. Designed to provide both expert guidance and step-by-step procedures, chapters serve to increase understanding in what, why, when, where, and how a particular assessment is used. Accessible and essential, Animal Models of Acute Neurological Injuries II: Injury and Mechanistic Assessments will be useful for trainees or beginners in their assessments of acute neurological injuries, for experienced scientists from other research fields who are interested in either switching fields or exploring new opportunities, and for established scientists within the field who wish to employ new assessments.

Historically the field of endocrine research has always been at the forefront of scientific endeavors. The investigators of these important breakthroughs in research have been rewarded by numerous Nobel awards. In the field of diabetes alone, Nobel prizes have been awarded to researchers who discovered insulin, characterized the protein and invented radioimmunoassays using insulin as a paradigm. Not surprisingly, biomedical researchers have always been attracted by the endocrine system and other similar systems of intercellular communication.
Over the past two decades, endocrine research has developed rapidly and adapted modern molecular and cellular biology techniques for its specific use. These changes have allowed researchers in the field to maintain their edge. Thus, endocrine disease-related genes have been characterized and mutations in these genes have helped explain common and
less common endocrine disorders. Our understanding of the regulation of gene expression has been greatly enhanced by molecular techniques.
In an attempt to bring investigators up to date with the recent advances in this exploding field we have decided to publish a series entitled Advances in Molecular and Cellular Endocrinology. Internationally famous investigators have agreed to participate and their contributions are appreciated.
Volume 1 has focused on aspects of the hypothalamic-pituitary axis including GnRH and GH gene regulation, molecular aspects of insulin, insulin-like growth factors and glucagon. In addition, reviews on the recently cloned calcium receptor and steroid receptor interactions with DNA are presented.

Covering an area of over 130 million km2 spanning the Mediterranean, equator and tropics, the African continent features a spectacular geographic diversity. Consequently, it is characterised by extremely variable climatic, edaphic and ecological conditions, associated with a wide range of natural vegetation and wildlife, as well as human population density, crops and livestock.

In this book, Henry Le Houerou presents his bioclimatic and biogeographic classification of Africa. The extensive data provide the basis for comparisons between various African regions, and with regions on other continents such as Latin America or the Indian subcontinent. The results constitute a rational basis for national, regional and sub-regional rural development planning, and for agricultural research dealing with aspects such as plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. Possible problems of applications are also examined."

This survey of one the longest insect conservation campaigns in Australia deals with recovery of one of the most iconic endemic butterflies, the Richmond birdwing, threatened by clearance and fragmentation of subtropical rainforest in eastern Australia and the spread of an alien larval food-plant. Its conservation has involved many aspects of community involvement, developed over more than 20 years, and focused on habitat restoration and weed eradication, in conjunction with conservation of remaining forest fragments. The work has involved the entire historical range of the butterfly, addressed threats and emphasised landscape connectivity, and has enhanced recovery through extensive plantings of native food plants. Interest has been maintained through extensive publicity, community education and media activity, and the programme has provided many lessons for advancing insect conservation practice in the region. "

This exciting volume offers an up-to-date tour of current trends in the neurobiology of memory while saluting Raymond Kesner's pioneering contributions to the field as a theorist and researcher, teacher and mentor. Starting with his signature chapter introducing the Attribute Model of Memory, the first half of the book focuses on the central role of the hippocampus in processing dimensions of space and time, and branches out to memory system interactions across brain structures. Later chapters apply the attribute model to multiple functions of memory in learning, and to specific neurological contexts, including Huntington's disease, traumatic brain injury, and Fragile X. As a bonus, the book concludes with an essay on Kesner's life and work, and reminiscences by colleagues. Among the topics covered: How the hippocampus supports the spatial and temporal attributes of memory. Self-regulation of memory processing centers of the brain. Multiple memory systems: the role of Kesner's Attribute Model in understanding the neurobiology of memory. Pattern separation: a key processing deficit associated with aging? * Prefrontal cortex and basal ganglia attributes underlying behavioral flexibility. Memory disruption following traumatic brain injury. Cognitive neuroscientists, neuropsychologists, gerontologists, psychiatrists, and neurobiologists will find The Neurobiological Basis of Memory both enlightening and inspiring--much like Kesner himself.

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.

Elwyn Simons has held professional appointments at Yale University (1960-1977), Duke University (1977-present), and was the Director of the Duke Primate Center (1977-1991) and Scientific Director (1991-2001). He has authored nearly 300 scientific publications and is the holder of many high honors. He is a member of the United States National Academy of Sciences, the American Philosophical Society, as well as many other professional associations. He was elected a Knight of the National Order by the government of Madagascar and has been the recipient of many awards including the prestigious Charles R. Darwin Award for Lifetime Achievement from the American Association of Physical Anthropologists. For nearly a half century, Dr. Simons has dominated the study of primate evolution. The volume summarizes the current state of knowledge in many aspects of primate and human evolution that have been studied by Simons and his colleagues and place it in a broader paleontological and historical perspective. Elwyn Simons: A Search for Origins contains the results of new research and reviews of many of the critical issues in primate and human evolution during the last half of the twentieth century as well as aspects of African paleontology and primate conservation in Madagascar. The authors are an extremely distinguished group of international authorities on all aspects of primate and human evolution and primate behavior. Although linked primarily by their connection to Simons? own career, the chapters include a wide range of important new works that are valuable contributions to the field of physical anthropology and paleontology and are certain to be widely cited and used in teaching.Several of the papers (Simons et al., Wing et al., Seiffert et al., Gingerich, O?Conner) are broad reviews of the history of research and discoveries in the fossil deposits of the Fayum, Egypt that have formed the background of our understanding of anthropoid evolution for over a century and will be important researchers for students and researchers in primate evolution and African paleontology. Similarly, broad reviews of the history of primate paleontology and human evolution (Rasmussen, Pilbeam, Wood; Sussman and Hart) will be essential reading in courses in primate and human evolution as well as the history of physical anthropology. Other authors describe new research results on early anthropoid fossils from Egypt (Kay and Simons) Tanzania (Stevens) and Myanmar (Gunnell and Ciochon). The chapter by John Oakley, Professor of Law at the University of California addresses the challenges to the teaching of evolution in schools- both public and universities world wide. Another major focus of several chapters are the primates of Madagascar. Two chapters are reviews of the extraordinary radiation of fossil lemurs (Godfrey et al, Jungers et al.). Two review the behavior and conservation of living lemurs (Taylor and Wright) and the chapter by Tattersall bridges the two major sections of the book by discussing about the biogeographic history of Malagasy mammals.

This book presents the latest information on canine parasites with zoonotic potential, to help avoid human infections. Compiled by international specialists, it covers protozoa, ectoparasites and helminth species of clinical importance in dogs, as well as the state of the art in diagnosis, preventive measures and potentially necessary treatment schemes. Dogs are commonly kept in families around the world and can predispose their human companions to disease. Updating and deepening insights from other specialist literature, the book is intended for practitioners and scientists alike. It also offers practical guidance for veterinary and human physicians and highlights unexplored research areas, making it a valuable resource for students and educated non-experts with an interest in parasitology, infectiology and zoonotic pet diseases.

Traditionally, behaviour and physiology have been considered two separate fields of biology with the majority of available literature focusing on one or the other. Recently the need for a multidisciplinary approach to these topics has been realised, highlighted by some of the sessions to be held at the 2003 annual meeting of the Society for Integrative and Comparative Biology such as 'regulation of behaviour' and' mechanisms of behaviour'. The proposed volume aims to bring together these disciplines in a comprehensive review of the available literature. Volume 24 will be novel in actively bridging these two areas of fish biology together and considering them as inextricably linked. The progression of chapters focuses on different aspects of the life history of a fish, from predator avoidance through to reproduction, each written by scientists currently bridging the gap between behaviour and physiology in their own specialised subdiscipline.
* Multidisciplinary and integrative research in fish biology
* Written by internationally recognized researchers
* Encompasses the whole life span of fish
* A wide variety of inter-related topics presented in a cohesive format

A valuable new reference on insect behavior, this exceptional new text delves into the primary sensory communication system used by most insects -- their sense of smell. This important text covers how insects produce pheromones and how they detect pheromones and plant volatiles. Since insects rely on pheromone detection for both feeding and breeding, a better understanding of insect olfaction and pheromone biosynthesis could help curb the behavior of pests without the use of harmful pesticides and even help to reduce the socio-economic impacts associated to human-insect interactions.
* Covers biochemistry and molecular biology of insect pheromone production
* Explains pheromone production in moths, beetles, flies, and social insects
* Describes pheromone and plant volatile reception

Nonhuman primates have played critical roles in biomedical research, and they are among the few animals whose use in research continues to increase. The scienti?c value of nonhuman primates derives from their close phylogenetic proximity to man and their consequent anatomic, physiologic, and genetic similarities to man. Only nonhuman primates can provide adequate models for many complex physiological and disease processes of humans. The baboon is a relative newcomer to the repertoire of nonhuman primates used in biomedical research. However, in less than 50 years since its ?rst use in the U. S. , it has become one of the most popular laboratory primate species. It is larger than the other widely used monkey species, making it advantageous for many types of experiments and technological developments. It is extraordinarily hardy and highly fecund in captivity. It closely resembles humans in a variety of physiological and disease processes, such as cholesterol metabolism, early stages of atherosclerosis, and alcoholic liver disease. Its chromosomes closely resemble those of humans, and many genes of the two species lie in the same chromosomal order. Among all primates, baboons are the most widely used models for the genetics of susceptibility to complex diseases and they are the ?rst nonhuman primate for which a framework genetic linkage map was established. In addition, the baboon genome is currently being sequenced, and as a result the utility of this species for biomedical research will be dramatically increased.

"Vascular Morphogenesis: Methods and Protocols" provides a range of techniques for studying vascular morphogenesis in vivo and in vitro, reflecting advances in the field. Endothelial cell signaling is currently believed to promote fundamental cues for cell fate specification, embryo patterning, organ differentiation and postnatal tissue remodeling. Understanding the concept of vascular bed specificity represents a major challenge for future investigations. Indeed, one of the most interesting theoretical perspectives and practical applications of endothelial cell signaling is the possibility for these cells to maintain their inductive potential during adult life. Written in the highly successful "Methods in Molecular Biology" series format, chapters include introductions to their respective topics, lists of the necessary materials, step-by-step, readily reproducible laboratory protocols and tips on troubleshooting and avoiding known pitfalls.

Practical and authoritative, "Vascular Morphogenesis: Methods and Protocols" will serve as a instructive and useful reference for cell biologists, anatomists, pathologists and physiologists, as well as all those interested in this area of biological study.

Progestins play a key role in reproductive endocrinology and as pharmaceutical drugs for contraception and in combined hormone therapy. To further our understanding of progestin action in the mammary gland, an international symposium, attended by leading researchers from academia and industry, was held in Berlin, 21 23 March 2007. Genetic mouse models helped to elucidate the role of progestins, both in normal breast development and in disease. Mechanistic molecular studies inspired the design of new progestins with improved tissue selectivity. In addition, the clinical impact of progesterone receptor agonists and antagonists for the prevention and treatment of breast cancer was discussed.

This book focuses on explaining the distribution of sexual systems (simultaneous hermaphroditism, sequential hermaphroditism, environmental sex determination,dioecy, androdioecy, etc.) among taxa, which remains a major challenge in evolutionary biology. Although significant advances have been made for angiosperms, there is not yet a theory that predicts the sexual system for the majority of animal taxa, and other taxa of plants also remain poorly understood. The problem, particularly for animals, is that sexual systems can be very conservative, with whole phyla and classes being characterized by a single sexual system; for example essentially the whole phylum Platyhelminthes is simultaneously hermaphroditic, whereas the Insecta (Hexapoda) and the Tetrapoda among the vertebrates, are exclusively dioecious. Sex allocation theory on the other hand, suggests that sexual systems should be highly responsive to evolution, changing with population density, life span, patterns of resource availability, etc. The book provides an overview of the topic and then presents a series of chapters, each dealing with a taxon with substantial lability in sexual system in order to identify the factors associated with changes in sexual system in each case. By doing so, the authors reveal factors that have not been considered in formal theory but seem to have a major impact on transitions between sexual systems. This book appeals to a wide readership in fields from zoology and evolutionary biology to botany.
