R3,069 Discovery Miles 30 690 Ships in 10 - 15 working days

This is a general introduction to the biology of bats, suitable as a text for courses in the subject, and as a reliable reference to all aspects of the subject for a broad range of biologists. The book presents a balanced coverage of the physiology, anatomy, behaviour, ecology, and phylogeny of bats. Bats comprise about one quarter of all mammalian species, and because of their diversity and their complex behaviours, they are among the most intensively studied groups in the Mammalia. Gerhard Neuweiler is an internationally recognized authority on bats, and one of the leading workers on the physiology of echolocation.

Mouse Genetics - Concepts and Applications (Hardcover, New): Lee M. Silver Mouse Genetics - Concepts and Applications (Hardcover, New)
Lee M. Silver
R3,286 Discovery Miles 32 860 Ships in 10 - 15 working days

Mouse Genetics offers for the first time in a single comprehensive volume a practical guide to mouse breeding and genetics. Nearly all human genes are present in the mouse genome, making it an ideal organism for genetic analyses of both normal and abnormal aspects of human biology. Written as a convenient reference, this book provides a complete description of the laboratory mouse, the tools used in analysis, and procedures for carrying out genetic studies, along with background material and statistical information for use in ongoing data analysis. It thus serves two purposes, first to provide students with an introduction to the mouse as a model system for genetic analysis, and to give practicing scientists a detailed guide for performing breeding studies and interepreting experimental results. All topics are developed completely, with full explanations of critical concepts in genetics and molecular biology. As investigators around the world are rediscovering both the heuristic and practical value of the mouse genome, the demand for a succinct introduction to the subject has never been greater. Mouse Genetics is intended to meet the needs of this wide audience.

Things have changed. In 1969 when the Convention for the Conservation of the Vicuna was drafted, in an attempt to save the vicuna from its tumbling decline towards extinction, both the science and the philosophy of wildlife conservation were radically different. It is thus a tribute to the prescience of those involved at the time that the rescue plan had, even through the harsh lens of hindsight, a d- tinctly Twenty First Century flavour. After all, it was predicated on the expectation that if vicuna could be saved, they would one day become a valued asset, generating revenue for the human communities that fostered their survival. Embodied in this aspiration are the main structures of modern biodiversity conservation - not only is it to be underpinned by science, but that science should be of both the natural and the social genres, woven into inter-disciplinarity, and thereby taking heed of e- nomics, governance, ownership and the like, alongside biology. In addition, it should include, as a major strut, the human dimension, taking account of the affected constituencies with their varied stakes in alternative outcomes. This c- temporary framework for thinking about biodiversity conservation is inseparable from such wider, and inherently political, notions as community-based conser- tion and ultimately sustainable use.

Across the globe, about 250 species of rodents spend most of their lives in safe and stable, but dark, oxygen-poor and carbon dioxide-rich burrows, deprived of most of the sensory cues available aboveground. They have become fully specialized for a unique way of life in which foraging and breeding take place underground. The systematic research into adaptations of subterranean dwellers is only about two decades old, but it has rapidly intensified within the last few years, bringing insight into many aspects of the biology and evolution at different organization levels.

Subterranean Rodents presents achievements from the last years of research on these rodents, divided into five sections: ecophysiology; sensory ecology; life histories, behavioural ecology and demography; environmental and economical impact; molecular ecology and evolution. It is a must for all researchers working in this field and will be of interest to zoologists, physiologists, morphologists, ecologists, and evolutionary biologists.

R4,170 Discovery Miles 41 700 Ships in 18 - 22 working days

Martens and Fishers (Martes) in Human-Altered Environments: An International Perspective examines the conditions where humans and martens are compatible and incompatible, and promotes land use practices that allow Martes to be representatively distributed and viable.

All Martes have been documented to use forested habitats and 6 species (excluding the stone marten) are generally considered to require complex mid- to late-successional forests throughout much of their geographic ranges. All species in the genus require complex horizontal and vertical structure to provide escape cover protection from predators, habitat for their prey, access to food resources, and protection from the elements. Martens and the fisher have high metabolic rates, have large spatial requirements, have high surface area to volume ratios for animals that often inhabit high latitudes, and often require among the largest home range areas per unit body weight of any group of mammals. Resulting from these unique life history characteristics, this genus is particularly sensitive to human influences on their habitats, including habitat loss, stand-scale simplification of forest structure via some forms of logging, and landscape-scale effects of habitat fragmentation. Given their strong associations with structural complexity in forests, martens and the fisher are often considered as useful barometers of forest health and have been used as ecological indicators, flagship, and umbrella species in different parts of the world. Thus, efforts to successfully conserve and manage martens and fishers are associated with the ecological fates of other forest dependent species and can greatly influence ecosystem integrity within forests that are increasingly shared among wildlife and humans.

We have made great strides in our fundamental understanding of how animals with these unique life history traits perceive and utilize habitats, respond to habitat change, and how their populations function and perform under different forms of human management and mismanagement. This knowledge enhances our basic understanding of all species of Martes and will help us to achieve the goal of conserving viable populations and representative distributions of the world's Martes, their habitats, and associated ecological communities in our new millennium.

At the beginning of the 20th century, scientists and laymen alike appear to have been peculiarly confident that the world had been thoroughly explored and most of its creatures named and documented. Few, if any, large animals still awaited discovery. The scientific unveiling of the giraffe-like okapi in 1901 was one of the earliest of this century's discoveries to shake this belief. But many consider it to be the last great find, and view the rediscovery of extinct animals to be as likely as the alchemic conversion of iron into gold. Since 1901, however, a whole host of new and rediscovered creatures has turned up to contradict these views-including a giant 7-ft-long forest hog from Africa, a colossal Indonesian monitor lizard called the Komodo dragon, the lobe-finned coelacanth fish resurrected from 64 million years of supposed extinction, the incredible megamouth shark, deep-sea tube-dwelling worms over 8 ft tall with huge red tentacles resembling strange alien flowers, plus the extraordinary Vu Quang ox and giant barking deer both discovered in Vietnam during the 1990s. And discoveries continue to be made today, in the 21st century-ranging diversely and dramatically from giant peccaries and zombie worms to an entire new suborder of insects known as the gladiators, a veritable jungle of new monkeys, and an extraordinary chameleonesque snake. And nor can we possibly forget the sensational rediscovery in North America of the near-legendary, supposedly long-extinct ivory-billed woodpecker. The Encyclopaedia of New and Rediscovered Animals is the third, wholly-updated edition of the very first-and still the definitive-book to be devoted to the spectacular zoological discoveries and equally amazing rediscoveries of the 20th century, which attracted international acclaim and exemplary reviews following its original publication in 1993 (when it was entitled The Lost Ark), and its subsequent republication in 2002 as an updated, greatly-expanded second edition (entitled The New Zoo). This latest edition also contains an in-depth survey of the 21st century's most celebrated discoveries and rediscoveries made during its first decade, plus an exhaustive, significantly-increased bibliography, as well as the only comprehensive collection of colour and b/w illustrations of these spectacular animal species ever published (including new, previously-unpublished photographs, and several exclusive, specially-commissioned full-colour paintings). Unquestionably, The Encyclopaedia of New and Rediscovered Animals provides good reason indeed for believing that our world continues to holds many more animal surprises in store for future revelation.

The last few years have seen a dramatic increase in the number of areas known to be involved in mammalian vision. It has also seen a far greater understanding of the importance of reciprocal connections, intrinsic connections, structure-specific modules and modules which span different structures, as well as the introduction of parallel processing models within the thalamocortical and corticocortical streams.

The body of knowledge has become so vast, and is growing so rapidly, that periodic updates are essential even for experts in the field. This volume is based on a satellite meeting of an international group of researchers. It emphasizes the most current information regarding midbrain and extrastriate mechanisms underlying vision and visually-guided behavior. The book also places these data into the larger context of how interrelated components of the visual system function to produce coherent visual experiences and behavior. New research findings are presented that are unavailable elsewhere, as well as reviews and broad perspectives in which existing data from multiple sources are brought together in order to help understand the structure and function of extrageniculostriate visual areas.

It is the goal of The Metabotropic Glutamate Receptors to provide acomprehensive and forward-thinking review ofthe tremen- dous advances that have occurred in less than a decade of metabotropic glutamate receptors (mGluR) research. Virtually every areaof mGluR research is covered, including the molecular biology, pharmacology, anatomical distribution, and physiological and pathological roles of mGluRs. It is our intention that this volume not only summarize what is now known about the mGluRs, but also illuminate the areas in which there is the greatest need for focused research. Glutamic acid is an amino acid that has long been known to play several important metabolic roles in central and peripheral tissues and to be a component of several naturally occurring molecules. The first evidence that glutamate mayaIso serve as a neurotransmitter in the central nervous system (CNS) came in the late 1950s and early 1960s when glutamate and other acidic amino acids were found to induce behavioral convulsions when topically applied to the cortex and to excite a wide variety of central neurons. These findings spurred a massive research effort that quickly established glutamate as the pri- mary excitatory neurotransmitter in the vertebrate CNS. One of the most striking characteristics of glutamate that was quickly recognized was its ubiquitous role in serving as the neurotransmitter at the vast majority of excitatory synapses in the brain. It is now clear that most central neuronal circuits involve glutamatergic neurotransmission at some level.

R3,445 Discovery Miles 34 450 Ships in 10 - 15 working days

Neuroscience Perspectives provides multidisciplinary reviews of topics in one of the most diverse and rapidly advancing fields in the life sciences. Whether you are a new recruit to neuroscience, or an established expert, look to this series for 'one-stop' sources of the historical, physiological, pharmacological, biochemical, molecular biological and therapeutic aspects of chosen research areas. The sigma receptor was originally thought to be a subset of the opioid receptor family, and it is less than 10 years since it was recognized that this receptor represents unique binding sites in mammalian brain and peripheral organs, distinct from any other known neurotransmitter receptor. Since the sigma receptors exhibit high affinity for members of diverse classes of psychotropic drugs, and have been postulated to be involved in various central nervous disorders, neuroscientists have demonstrated a great deal of interest in the elucidation of these receptor sites and their biological relevance. Relatively little is known about the precise role of sigma receptors in normal brain function and in CNS disorders, despite an overwhelming research effort. This research has resulted in many controversies, some of which have been reconciled while others have not. This volume aims to update the reader on the current situation, and deals with the potential functional significance of these receptors in the brain and peripheral organs and, where appropriate, makes reference to the clinical potential of these sites.

This volume comprises the edited proceedings of the International Taurine Sympo sium held in Osaka, Japan, in June 1995, as a Satellite Symposium of the 15th Biennial of the International Society for Neurochemistry. This Taurine Symposium was the Meeting latest in a series held since 1975 at approximately two-year intervals by an informal group of international researchers. It attracted contributions from 20 countries, ranging from Armenia via Finland and Spain to the United States. Some 121 participants attended. The Symposium was organized and chaired by Junichi Azuma, University of Osaka. Other members of the Organizing Committee in Japan consisted of Kinya Kuriyama and Masao Nakagawa, both from the Kyoto Prefectural University of Medicine, and Akemichi Baba, from Osaka University. The Committee had to contend with the disaster of the Kobe earthquake, which struck on January 21. The epicenter was only around 25 miles from the meeting site, and the quake demolished the home of one Committee member. Despite this unnaturally natural handicap, the participants experienced a superbly organized meeting, one which more than maintained the high social and scientific standards established for this series. In his Welcome Message, Dr. Azuma listed a threefold objective for the Symposium: To provide a forum for the interdisciplinary exchange of information on taurine; to give an opportunity for renewing old friendships and making new friends; and to promote coopera tion among participants from around the world."

The Springer Handbook of Auditory Research presents a series of com prehensive and synthetic reviews of the fundamental topics in modern auditory research. It is aimed at all individuals with interests in hearing research including advanced graduate students, postdoctoral researchers, and clinical investigators. The volumes will introduce new investigators to important aspects of hearing science and will help established inves tigators to better understand the fundamental theories and data in fields of hearing that they may not normally follow closely. Each volume is intended to present a particular topic comprehensively, and each chapter will serve as a synthetic overview and guide to the literature. As such, the chapters present neither exhaustive data reviews nor original research that has not yet appeared in peer-reviewed journals. The series focusses on topics that have developed a solid data and con ceptual foundation rather than on those for which a literature is only beginning to develop. New research areas will be covered on a timely basis in the series as they begin to mature."

This book, the second in Chapman & Hall's Wildlife Ecology and Behaviour Series, focuses on studies of both European and Siberian roe deer to provide an authoritative insight into their taxonomy, ecology, feeding patterns, social behaviour and population dynamics. It uses this information to tackle the fascinating question of what environmental factors underly ranging patterns and trigger migratory behaviour in some populations but not in others, adding new perspectives and depths to our understanding of general issues in behavioural ecology. This book is an important addition to the literature on ungulate ecology, offering for the first time in the English language, a distillation of the knowledge and understanding gathered in over twenty years' ground breaking research by Aleksey Danilkin and other Russian and Eastern European researchers on European and Siberian roe deer. Mark Hewison's extensive experience with European roe deer in France and Great Britain ensures the work presents a definitive and integrated analysis of the current state of knowledge on roe deer worldwide. Students and researchers in zoology, conservation, ecology and wildlife management as well as many naturalists will welcome this stimulating synthesis.

The observation that neuropeptide Y (NPY) is the most abundant peptide present in the mammalian nervous system and the finding that it elicits the most powerful orexigenic signal have led to active investigations of the properties of the NPY family of hormones, including peptide YY (PYY) and pancreatic polypeptide (PP). Nearly two decades of research have led to the identification of several NPY receptor subtypes and the development of useful receptor selective ligands. Moreover, these investigations have imp- cated NPY in the pathophysiology of a number of diseases, including feeding disorders, seizures, memory loss, anxiety, depression, and heart failure. Vigorous efforts are therefore continuing, not only to understand the bioche- cal aspects of NPY actions, but also toward developing NPY-based treatments for a variety of disorders. To facilitate these efforts, it was decided to produce the first handbook on NPY research techniques as part of the Methods in Molecular Biology Series. In compiling Neuropeptide Y Protocols, I have gathered contributions on techniques considered critical for the advancement of the NPY field from experts in various disciplines. Each chapter starts with a brief introduction, with Materials and Methods sections following. The latter sections are presented in an easy to follow step-by-step format. The last section of the chapter, Notes, highlights pitfalls and the maneuvers employed to overcome them. This information, not usually disseminated in standard research pub- cations, may prove extremely useful for investigators employing these te- niques in NYP research.

Arid lands require that organisms inhabiting them be well-adapted to thrive or even just to survive. This book provides a review of the ecological adaptations - be they behavioural, physiological or morphological - of carnivores to arid environments. Following a general introduction into aridity and arid lands in Africa, the major carnivore families are presented. Ecological adaptations of carnivores in arid lands reveal the amplitude and resilience of the ecology of these animals. In setting up conservation measures, the nature and extent of such adaptations are important facets in determining the effective area and degree of heterogeneity required as habitat by a carnivore population so as to produce a viable unit.

The Preface to the first edition of this book explained the reasons for the publication of a comprehensive text on the rumen and rumen microbes in 1988. The microbes of the ruminant's forestomach and those in related organs in other animals and birds provide the means by which herbivorous animals can digest and obtain nutriment from vegetation. In turn, humans have relied, and still do rely, on herbivores for much of their food, clothing and motive power. Herbivores also form the food of carnivorous animals and birds in the wild. The importance of the rumen microorganisms is thus apparent. But, while a knowledge of rumen organisms is not strictly neces sary for the normal, practical feeding of farm animals, in recent years there has been much more emphasis on increasing the productivity of domesti cated animals and in rearing farm animals on unusual feedstuffs. Here, a knowledge of the reactions of the rumen flora, and the limits to these reactions, can be invaluable. In addition, anaerobic rumen-type microor ganisms are found in the intestines of omnivores, including humans, and can be implicated in diseases of humans and animals. They are also found in soils and natural waters, where they playa part in causing pollution and also in reducing it, while the same organisms confined in artificial systems are essential for the purification of sewage and other polluting and toxic wastes."
