SHORTLISTED FOR THE TS ELIOT PRIZE FOR POETRY 2020 WINNER OF THE SCOTTISH BOOK AWARDS' POETRY BOOK OF THE YEAR A POETRY BOOK SOCIETY RECOMMENDATION SHORTLISTED FOR THE JOHN POLLARD FOUNDATION INTERNATIONAL POETRY PRIZE "Whip-smart, sonically gorgeous" - Rae Armantrout, author of the Pulitzer Prize winning Versed When Louis Pasteur observed the process of fermentation, he noted that, while most organisms perished from lack of oxygen, some were able to thrive as 'life without air'. In this capricious, dreamlike collection, characters and scenes traverse states of airlessness, from suffocating relationships and institutions, to toxic environments and ecstatic asphyxiations. Both compassionate and ecologically nuanced, this innovative collection bridges poetry and prose to interrogate the conditions necessary for survival.
The first book on zoo/captive animal behavior and how this applies to welfare. Despite growing evidence of the need to implement more suitable, naturalistic practices into zoo animal welfare, it still seems to be somewhat overlooked - this book will address this oversight. Includes specific detail and examples focusing on taxa, a huge factor in managing animals in zoos that has not previously been addressed in this way. Covers invertebrates as well as vertebrate species. Would be a recommended or core text on Zoo Biology courses, BScs in Animal Science, and Animal Welfare MScs, as well as an invaluable practitioner reference. A lot of students interested in animal behaviour are interested in zoos. Each chapter covers species-specific content include the following information: Ecology and natural history as relevant to the zoo, behaviour and welfare measures based on ecological knowledge, feeding ecology and nutritional management, mating systems and reproductive characteristics, enrichment and behavioural diversity. The chapters are consistently formatted for ease of information, with end of chapter summaries, boxes with selected enrichment devices or welfare assessment methods for assessing welfare state, and directed reading of peer reviewed and other reputable sources that help advance care. A final Part explores welfare assessment tools, quality of life, veterinary interventions and evidence-based approaches. It looks at ways to increase the value of zoo and aquarium animals by enhancing visitor interest and visitor behaviour change. Also, research needs for keepers and how to build evidence into a daily routine, as well as management of native species programmes and the future of zoo research.
In recent years, progress in fish biology has advanced at an unprecedented rate and has led to many breakthroughs in the field. This book provides a wealth of information on the strategies that fish adopt with respect to waters with markedly different physical and chemical characteristics. It shows how their physiology, behaviour and lifestyles are adapted to exploit particular niches and gives comprehensive insight into fish life under extreme conditions. The readers are introduced to the ways in which fish exemplify many phenomena of general biological interest - the existence of competitors, chaos, and predator-prey interaction. Fish pathology as well as the components of the immune system are addressed. In this book, original and at times controversial views are presented, areas which have so far received inadequate attention are highlighted and avenues for further research are suggested.
Mangrove forests, seagrass beds, and coral reefs are circumtropical ecosystems that are highly productive, and provide many important biological functions and economic services. These ecosystems cover large surface areas in the shallow tropical coastal seascape but have suffered from serious human degradation, especially in the last few decades. Part of their diversity, productivity, and functioning seems to be based on their juxtaposition. Especially in the last decade significant advances have been made on new insights into their ecological connectivity. This authoritative book provides a first-time comprehensive review of the major ecological interactions across tropical marine ecosystems that result from the mutual exchange of nutrients, organic matter, fish, and crustaceans. A group of leading authors from around the world reviews the patterns and underlying mechanisms of important biogeochemical and biological linkages among tropical coastal ecosystems in 15 chapters. Included are chapters that review cutting-edge tools to study and quantify these linkages, the importance of such linkages for fisheries, and how tropical ecosystems should be conserved and managed for sustainable use by future generations. The book uses examples from all over the world and provides an up-to-date review of the latest published literature. This book is a 'must read' for professionals working on the conservation, management, and ecology of mangrove, seagrass and coral reef ecosystems.
Whatever theory may be advanced to explain diurnal migration, the underlying reactions involved must be demonstrated conc- sively in the laboratory before the explanation can be ?nally accepted George L. Clarke 1933 p. 434 In oceans and lakes, zooplankton often make diel vertical migrations (DVM), descending at dawn and coming up again in late afternoon and evening. The small animals cover distances of 10-40 m in lakes or even a few hundred metres in the open oceans. Although not as spectacular as migrations of birds or the massive movements of large mammals over the African savannas, the numbers involved are very large and the biomass exceed the bulk of the African herds. For example, in the Antarctic oceans swarms of "Krill" may cover kilometres across, with thousands of individuals per cubic metre. These Euphausiids are food for whales, the most bulky animals on earth. Zooplankton are key species in the pelagic food web, intermediary between algae and ?sh, and thus essential for the functioning of the pelagic community. Prey for many, they have evolved diverse strategies of survival and DVM is the most imp- tant one. Most ?sh are visually hunting predators and need a high light intensity to detect the often transparent animals. By moving down, the well-lit surface layers are avoided but they have to come up again at night to feed on algae.
Animals perform many athletic tasks to an amazing degree of accomplishment: not only spectacular feats of running and jumping but also routine actions that ensure survival such as feeding, vocalization, diving, flying, and many more. The study of performance capacity (defined as the ability of an animal to conduct a key task) is of great interest to both ecologists and evolutionary biologists. At an ecological level, how well individuals perform often dictates opportunities for reproduction, occupation of preferred territories, or capturing prey. Therefore, variation in performance capacities can be a key determinant of variation in fitness within animal populations. At an evolutionary level, variation in function often follows closely from variation in form, and therefore enables animals to invade novel habitats, or to overtake other species. This novel book examines how and why animal athletes have evolved. It uses examples from across the animal kingdom and integrates them in the broader context of ecology and evolution, thereby identifying common themes that transcend taxonomic divisions. Animal Athletes is an accessible textbook of particular relevance to undergraduates, graduate students, researchers, and professionals in the fields of evolutionary biology, ecology, vertebrate morphology, and functional morphology, and will also appeal to the interested layperson.
This book examines the contents, influence, and potential of a personal selection of modern books published over the last fifty years that have been relevant to improving welfare. The works selected comprise three earlier classics that mainly deal with animal experimentation and intensive farming, as well as five that concentrate on specific subject areas, namely history, science, applied ethics, politics and law, that are important to protecting the welfare of animals against suffering inflicted by humans. The books are arranged in the order of their publication date, and for each one a few related works are also mentioned or discussed. This collection provides a broad understanding of animal protection issues, and provides the necessary basis for an informed and comprehensive approach to improving the welfare of animals. The books selected have been influential and they have the potential to improve animal welfare in the future.
The book presents a chronology of events of B. tabaci and geminiviruses, and an overview within the Caribbean and Latin America. The pathosystems involving Tomato yellow leaf curl virus, Cotton leaf curl virus and the cassava mosaic viruses are discussed. Data is presented on amino acid concentrations influencing B. tabaci and thus serves the basis for holidic diets. The essential molecular techniques for B. tabaci identification and classification are included with factors to consider for appropriate applications; an essential working guide for graduate students and researchers in the molecular field. Excellent photos portray symptoms of geminivirus-infecting crops: tomato, cotton, cassava, legumes and cucurbits; an important guide for researchers and growers. The novel insecticides, their mode of action and specificity; emphasize the applications of these within IPM programs.
Hemiptera - Heteroptera encompasses the three well-defined suborders of the true bugs which are adapted to an aquatic or littoral habitat. The book begins with a section on the biology these insects and provides illustrations of the basic features of their morphology and outlines the larval development. Brief outlines of the ecological and zoogeographical peculiarities of the three aquatic suborders are presented individually, and various methods for observing, collecting, preserving, rearing, and examining specimens are discussed. Most of the book is devoted to keys for the identification of adults to species, and notes are provided that will help recognize the known larvae. Unlike most other aquatic insects, the larval instars of the heteropteran species closely resemble the adults in their morphology, preferred habitats, and feeding habits. Therefore, distinguishing features of those relatively few larvae which have been described in detail are usually mentioned in the keys to the adults rather than being included in separate keys. In addition to the most important features for determining the individual species, many keys include additional notes on the morphology, which is intended to give the user a better chance of recognizing specimens of species not yet known to science. After the currently recognized name of each species, the known range is provided. Regions of the world outside of South America, South American countries, and the states of Brazil from which the species has been reported are listed. Following the range information, major synonyms previously used for the species in the literature are provided. If subspecies have been described and are still recognized as such, they are also discussed. Finally, if the status of the species is regarded as uncertain because of a poor description, strong resemblance to another species, or any other reason, a note is added that a detailed study will be necessary to clarify the status of the taxon. Taxonomic revisions in the book itself are strictly avoided. To provide the user of the keys with maximum assistance in making reliable identifications, the book is richly illustrated with pen and ink drawings of thousands of individual morphological structures arranged in 820 figures. The book is intended to make a significant impact toward popularizing the study of South American water bugs by assembling and condensing the information in hundreds of individual publications on the group, which appeared in many books and journals published in many different countries over the past 200 years. Some of these works are very difficult to obtain in South America, and their lack creates serious impediments to systematic, ecological, and zoogeographical research. In the more than 730 titles appearing in the bibliography, the original descriptions and revisions of almost all South American species can be found.
comprehensively up to date. We are most grateful to these authors and to those we recruited to write the additional chapters necessary to fill the significant gaps. We acknowledge also the sacrifice of some who presented results of original research and have thus suffered a longer time than usual to publication. The timing of publication however has provided the opportunity to highlight recent discussions and resolutions made within the Antarctic Treaty forum to protect wildlife against disease and to include responses by Government and non-Government operators in Antarctica. These developments mostly followed from the Workshop on Diseases of Antarctic Wildlife. The book comprises 17 chapters presented in two parts. Wildlife disease consists of reviews, case studies and health assessments, and External factors covers the environmental, administrative and legal aspects. Each chapter is complete and c- tains all references. Six important documents are provided as Appendices. These present methods, reviews and other documents which are referred to in one or more chapters but are not readily available. There are many related topics we have been unable to cover that would enhance the understanding of health and disease processes in Antarctica. While we ackno- edge their importance they are outside the scope of the present volume. Such topics include epidemiology, new and emerging infectious diseases and the effects of climate change. These topics are referred to in the various chapters where ref- ences to source material are given.
Much of the country's recent population growth is situated in exurban areas. By many accounts exurbanization has become the dominant pattern of land development in the country and there is no indication it will slow in the foreseeable future (Theobald 2005; Brown et al. 2005; Glennon and Kretser 2005). By definition, exurban development takes place beyond the metropolitan fringe, often in rural and remote areas. The development of new exurban communities is a growing trend, especially in the West. In this case, developers and homebuilders seek large tracts of land, up to thousands of acres, in rural areas (typically within 50 miles of a large city) where they plan entire communities consisting of commercial, retail and residential land uses. Recreational amenities such as golf courses and hiking/biking trails are often included in these master-planned developments. Our philosophy is reflected in the book's two objectives. First, we seek to document the extent and impacts of exurban development across the country. At issue is demonstrating why planners and the public-at-large should be concerned about exurbanization. We will demonstrate that even though exurbanization favors amenity rich regions, it affects all areas of the country through the loss of agricultural and grazing lands, impacts to watersheds and land modification. A summary of environmental impacts is presented, including the loss of wildlands and agricultural productivity, land modification, soil erosion, impacts to terrestrial hydrologic systems, the loss of biodiversity, nonnative and endangered species and other topics. Our second aim is to provide readers from diverse (nonscientific) backgrounds with a working knowledge of how and why exurbanization impacts environmental systems. This is accomplished by working closely to ensure contributors follow a specific outline for each chapter. First, contributors will spell out fundamental concepts, principles and processes that apply to their area of expertise (e.g., riparian areas). Contributors will move beyond a cursory understanding of ecological processes without overwhelming readers with the dense material found typically in specialized texts. For this reason, visuals and other support materials will be integral to each chapter. We have chosen contributors carefully based on their record as research scientists and acumen as educators. Second, once the mechanics have been laid out, authors will explain how and why land development in nearby areas influences ecosystems. Issues of interdependency, modification and adaptation, spatial scale and varying time horizons will be featured. Third, contributors will weigh in on the pros and cons of various land-development schemes. Fourth, authors will share their thinking on the merits of conservation devices such as wildlife corridors, open-space requirements and watershed management districts. Finally, each chapter will conclude by identifying pitfalls to avoid and highlighting "best practices" that will mitigate environmental problems or avoid them altogether. In sum, after completing each chapter, readers should have a firm grasp of relevant concepts and processes, an understanding of current research and know how to apply science to land-use decisions.
If you're thinking of Jason and the Argonauts, think again. In this book, the golden mouse is used as a model to explore conceptual issues in ecology across all levels of organization from organism to landscape, integrating reductionist and holistic ecological science. Through intensive study of a single species, the authors demonstrate biological and ecological information applicable to many fields, including conservation and resource management.
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.
This book provides a comprehensive survey of the diversity and biology of metazoan parasites affecting small mammals, of their impact on host individuals and populations, and of the management implications of these parasites for conservation biology and human welfare. Designed for a broad, multidisciplinary audience, the book is an essential resource for researchers, students, and practitioners alike.
This book is concerned with two problems: how eusociality, in which one individual forgoes reproduction to enhance the reproduction of a nestmate, could evolve under natural selection, and why it is found only in some insects-termites, ants and some bees and wasps. Although eusociality is apparently confined to insects, it has evolved a number of times in a single order of insects, the Hymenoptera. W. Hamilton's hypothesis, that the unusual haplodiploid mechanism of sex determination in the Hymenoptera singled this order out, still seems to have great explanatory power in the study of social ants. We believe that the direction, indeed confinement, of social altruism to close kin is the mainspring of social life in an ant colony, and the alternative explanatory schemes of, for example, parental manipu lation, should rightly be seen to operate within a system based on the selective support of kin. To control the flow of resources within their colony all its members resort to manipulations of their nestmates: parental manipulation of offspring is only one facet of a complex web of manipul ation, exploitation and competition for resources within the colony. The political intrigues extend outside the bounds of the colony, to insects and plants which have mutualistic relations with ants. In eusociality some individuals (sterile workers) do not pass their genes to a new generation directly. Instead, they tend the offspring of a close relation (in the simplest case their mother).
The book will cover the entire range of the Painted Stork--beyond its stronghold in India and Sri Lanka to other countries--E Asia as well. For the sake of comparison, relevant information will be included about the other species of storks--both solitary as well as colonial, of Asia, as well as those in other parts of the world. Certainly plenty of references will be made about the work done on the American Wood Stork. Studies are underway in order to better understand the role of the monsoon rains on the nesting pattern of Painted Stork, besides attempting a review of the global status of the species. The former is likely to be of interest in augmenting our understanding about how global climate change is going to affect birds across India and the second is likely to raise interesting points about the distribution of species and their ranges. Both these studies will be carried through 2009 and should hopefully be included in the proposed book. Naturally, the focused interest in field research on the Painted Stork has resulted in accumulation of considerable information on this particular species, which is beyond the information contained on some standard Indian and international works and ornithological texts. The author hopes to include the entire spread of information of this species--from its systematics, evolution, distribution, ecology to its role in human culture as well as its association with mythologies. In other words, topics have not been restricted to the areas of the author's research but have spilled over into areas of anthropology, ecology, conservation, etc.
Given the importance of livestock to the global economy, there is a substantial need for world-class reference material on the sustainable management of livestock in diverse eco-regions. With uncertain climates involving unpredictable extreme events (e.g., heat, drought, infectious disease), environmental stresses are becoming the most crucial factors affecting livestock productivity. By systematically and comprehensively addressing all aspects of environmental stresses and livestock productivity, this volume is a useful tool for understanding the various intricacies of stress physiology. With information and case studies collected and analyzed by professionals working in diversified ecological zones, this book explores the influence of the environment on livestock production across global biomes. The challenges the livestock industry faces in maintaining the delicate balance between animal welfare and production are also highlighted.
The Arctic, the Antarctic, and the Hindu Kush-Himalayas form a trio of terrains sometimes called "the three poles". Mainly composed of rock, snow, and ice, these precious regions, which are home to many unique species such as the polar bear, the emperor penguin, and the snow leopard, contain the primary water resource of this planet and directly shape our climate. This book presents a first-ever global assessment and progressive review of the three poles and demonstrates the urgent need for their protection. Sins of the past have irrevocably harmed and threatened many of the unique qualities of these regions, and the future looks bleak with the global population forecast to reach 9 billion by 2060, and with climate change on the rise. Presented here is a wide-reaching and coherent overview of the three poles' biodiversity, habitats, and ongoing destruction. Failed protection and social targets set by the United Nations and other bodies are exposed while economic growth, unconstrained or inappropriate development, and urban sprawl are promoted unabated. Polar regions play a major role in the global agenda as they are rich in oil and other resources, marking them for contamination, overfishing, and further degradation. Tourism in the Antarctic has benefited from enlightened self-regulation, but there are signs that this is changing, too. The chapters of this book are written by experts in their fields, and their evidence leaves no doubt that we already live beyond our carrying capacity on a finite but decaying space. A global protection role model and several outlook scenarios are proposed to help set in motion polar protection priorities that are actually valid. Humanity has demonstrated through international treaties such as the Antarctic Treaty and the Madrid Protocol that we can put the interests of the planet as a whole first. This must become the norm, not the exception.
Empirical in character, this book analyses the society-nature interaction of the Tsimane', a rural indigenous community in the Bolivian Amazon. Following a common methodological framework, the material and energy flow (MEFA) approach, it gives a detailed account of the biophysical exchange relations the community entertains with its natural environment: the socio-economic use of energy, materials, land and time. Equally so, the book provides a deeper insight into the local base of sociometabolic transition processes and their inherent dynamics of change. The local community described in this publication stands for the many thousands of rural systems in developing countries that, in light of an ever more globalising world, are currently steering a similar - but maybe differently-paced - development course. This book presents insightful methodological and conceptual advances in the field of sustainability science and provides a vital reader for students and researchers of human ecology, ecological anthropology, and environmental sociology. It equally contributes to improving professional development work methods.
With over 43,000 species, spiders are the largest predacious arthropod group. They have developed key characteristics such as multi-purpose silk types, venoms consisting of hundreds of components, locomotion driven by muscles and hydraulic pressure, a highly evolved key-lock mechanism between the complex genital structures, and many more unique features. After 300 million years of evolutionary refinement, spiders are present in all land habitats and represent one of the most successful groups of terrestrial organisms. Ecophysiology combines functional and evolutionary aspects of morphology, physiology, biochemistry and molecular biology with ecology. Cutting-edge science in spiders focuses on the circulatory and respiratory system, locomotion and dispersal abilities, the immune system, endosymbionts and pathogens, chemical communication, gland secretions, venom components, silk structure, structure and perception of colours as well as nutritional requirements. Spiders are valuable indicator species in agroecosystems and for conservation biology. Modern transfer and application technologies research spiders and their products with respect to their value for biomimetics, material sciences, and the agrochemical and pharmaceutical industries.
This book summarises the newest information on seasonal adaptation in animals. Topics include animal hibernation, daily torpor, thermoregulation, heat production, metabolic depression, biochemical adaptations, neurophysiology and energy balance. The contributors to this book present interdisciplinary research at multiple levels ranging from the molecular to the ecophysiological, as well as evolutionary approaches. The chapters of this book provide original data not published elsewhere, which makes it the most up-to-date, comprehensive source of information on these fields. The book s subchapters correspond to presentations given at the 14th International Hibernation Symposium in August 2012 in Austria. This is a very successful series of symposia (held every four years since 1959) that attracts leading researchers in the field. Like the past symposia, this meeting and consequently the book is aimed not only at hibernation but at covering the full range of animal adaptations to seasonal environments. For the next four years, this book will serve as the cutting-edge reference work for graduate students and scientists active in this field of physiology and ecology.."

How birds have evolved and adapted to survive winter Birds in Winter is the first book devoted to the ecology and behavior of birds during this most challenging season. Birds remaining in regions with cold weather must cope with much shorter days to find food and shelter even as they need to avoid predators and stay warm through the long nights, while migrants to the tropics must fit into very different ecosystems and communities of resident birds. Roger Pasquier explores how winter affects birds' lives all through the year, starting in late summer, when some begin caching food to retrieve months later and others form social groups lasting into the next spring. During winter some birds are already pairing up for the following breeding season, so health through the winter contributes to nesting success. Today, rapidly advancing technologies are enabling scientists to track individual birds through their daily and annual movements at home and across oceans and hemispheres, revealing new and unexpected information about their lives and interactions. But, as Birds in Winter shows, much is visible to any interested observer. Pasquier describes the season's distinct conservation challenges for birds that winter where they have bred and for migrants to distant regions. Finally, global warming is altering the nature of winter itself. Whether birds that have evolved over millennia to survive this season can now adjust to a rapidly changing climate is a problem all people who enjoy watching them must consider. Filled with elegant line drawings by artist and illustrator Margaret La Farge, Birds in Winter describes how winter influences the lives of birds from the poles to the equator.
Not all stress is stressful; instead, it appears that stress in the environment, below the mutation threshold, is essential for many subtle manifestations of population structures and biodiversity, and has played a substantial role in the evolution of life. Intrigued by the behavior of laboratory animals that contradicted our current understanding of stress, the author and his group studied the beneficial effects of stress on animals and plants. The seemingly "crazy" animals demonstrated that several stress paradigms are outdated and have to be reconsidered. The book describes the general stress responses in microorganisms, plants, and animals to abiotic and biotic, to natural and anthropogenic stressors. These stress responses include the activation of oxygen, the biotransformation system, the stress proteins, and the metal-binding proteins. The potential of stress response lies in the transcription of genes, whereas the actual response is manifested by proteins and metabolites. Yet, not all stress responses are in the genes: micro-RNAs and epigenetics play central roles. Multiple stressors, such as environmental realism, do not always act additively; they may even diminish one another. Furthermore, one stressor often prepares the subject for the next one to come and may produce extended lifespans and increased offspring numbers, thus causing shifts in population structures. This book provides the first comprehensive analysis of the ecological and evolutionary effects of stress.
Biodiversity and its conservation are among the main global topics in science and politics and perhaps the major challenge for the present and coming generations. This book written by international experts from different disciplines comprises general chapters on diversity and its measurement, human impacts on biodiversity hotspots on a global scale, human diversity itself and various geographic regions exhibiting high levels of diversity. The areas covered range from genetics and taxonomy to evolutionary biology, biogeography and the social sciences. In addition to the classic hotspots in the tropics, the book also highlights various other ecosystems harbouring unique species communities including coral reefs and the Southern Ocean. The approach taken considers, but is not limited to, the original hotspot definition sensu stricto and presents a chapter introducing the 35th hotspot, the forests of East Australia. While, due to a bias in data availability, the majority of contributions on particular taxa deal with vertebrates and plants, some also deal with the less-studied invertebrates. This book will be essential reading for anyone involved with biodiversity, particularly researchers and practitioners in the fields of conservation biology, ecology and evolution. |
