Terry Maple, Bonnie M Perdue
R5,700 Discovery Miles 57 000 Ships in 10 - 15 working days

Zoo Animal Welfare thoroughly reviews the scientific literature on the welfare of zoo and aquarium animals. Maple and Perdue draw from the senior author's 24 years of experience as a zoo executive and international leader in the field of zoo biology. The authors' academic training in the interdisciplinary field of psychobiology provides a unique perspective for evaluating the ethics, practices, and standards of modern zoos and aquariums. The book offers a blueprint for the implementation of welfare measures and an objective rationale for their widespread use. Recognizing the great potential of zoos, the authors have written an inspirational book to guide the strategic vision of superior, welfare-oriented institutions. The authors speak directly to caretakers working on the front lines of zoo management, and to the decision-makers responsible for elevating the priority of animal welfare in their respective zoo. In great detail, Maple and Perdue demonstrate how zoos and aquariums can be designed to achieve optimal standards of welfare and wellness.

Wetland Techniques - Volume 2: Organisms (Paperback, 2013 ed.): James T. Anderson, Craig A. Davis Wetland Techniques - Volume 2: Organisms (Paperback, 2013 ed.)

Wetlands serve many important functions and provide numerous ecological services such as clean water, wildlife habitat, nutrient reduction, and flood control. Wetland science is a relatively young discipline but is a rapidly growing field due to an enhanced understanding of the importance of wetlands and the numerous laws and policies that have been developed to protect these areas. This growth is demonstrated by the creation and growth of the Society of Wetland Scientists which was formed in 1980 and now has a membership of 3,500 people. It is also illustrated by the existence of 2 journals ("Wetlands" and "Wetlands Ecology and Management") devoted entirely to wetlands.

To date there has been no practical, comprehensive techniques book centered on wetlands, and written for wetland researchers, students, and managers. This techniques book aims to fill that gap. It is designed to provide an overview of the various methods that have been used or developed by researchers and practitioners to study, monitor, manage, or create wetlands. Including many methods usually found only in the peer-reviewed or gray literature, this 3-volume set fills a major niche for all professionals dealing with wetlands."

Private or Socialistic Forestry? - Forest Transition in Finland vs. Deforestation in the Tropics (Paperback, 2012 ed.): Matti... Private or Socialistic Forestry? - Forest Transition in Finland vs. Deforestation in the Tropics (Paperback, 2012 ed.)
Matti Palo, Erkki Lehto
R5,634 Discovery Miles 56 340 Ships in 10 - 15 working days

While deforestation continues at an alarming rate around the world, discussions on the range of underlying causes continue. The premise is that studying successful transitions from deforestation to sustainable forestry ex post in Finland can provide novel insights into how deforestation in the tropics might be reduced in the future. Our fundamental question here is why Finland succeeded to stop deforestation for a century ago and why not the same is feasible in the contemporary tropical countries? This book presents a novel integrated theory within which this case study on Finland and contemporary modeling of underlying causes of tropical deforestation are developed. Finland remains the world's second largest net exporter of forest products, while maintaining the highest forest cover in Europe. A transition from deforestation to sustainable industrial forestry took place in Finland during the first part of the 20th century. The underlying causes of this transition are compared via our theory with deforestation in 74 contemporary tropical countries. Both appear similar and support our theory. The interaction of public policies and market institutions has appeared to be critical during this transition. The study's findings suggest that private forest ownership with a continuous increase in the real value of forests and alleviation of poverty under non-corruptive conditions has been a necessary, but not a sufficient, condition for this transition. In a parallel way public policies have also proved to be a necessary, but not sufficient, condition in this transition. The conclusion is that socialistic forestry along with corruption is artificially maintaining too low values in the tropical forests. The opportunity cost of sustainable forestry remains too high and deforestation by extensification of agriculture therefore continues. The prevailing socialistic forestry with dominating public forest ownership is by purpose maintaining administratively set low stumpage prices leading to low value of forests, wide corruption and continuous forest degradation and deforestation. An effective remedy - to raise the value of forests - is found to be within forestry.

R4,335 Discovery Miles 43 350 Ships in 10 - 15 working days

Natural resource management by rural citizens in tropical regions is crucial both to the conservation of biodiversity and ecosystem processes, but also to the the well-being and food security of the people that live there. This situation is especially acute in Africa where conflicts between habitat destruction and utilization can arise in areas which are important not only for biodiversity but for the long-term maintenance of ecosystems on which the people ultimately rely. There can also be conflicts between outside specialists and the indigenous knowledge of local communities. A holistic approach involving local peoples in management of their natural resources is therefore essential. A range of approaches to the problem is explored here in relation to natural resource management to local development and livelihoods, and the multi-functional nature of land-use. Major topics debated are the dichotomy between strictly protected areas and ones including human activity, people-centred rather than legally enforced conservation, market forces, and the interrelationships between agriculture and conservation. The book has 12 chapters, prepared by researchers actively involved in community aspects of natural resource management in Africa, and is based on an international workshop held in Niamey, Niger, in 2008. It will be of interest to all involved in the community approach to biodiversity conservation in less developed countries generally and not only in Africa as many of the issues addressed are pertinent globally.

'I found myself turning the pages with an inward leap of joy' - Isabella Tree *Shortlisted for the James Cropper Wainwright Prize for Conservation* *Shortlisted for the Richard Jefferies Award for Nature Writing* 'Exquisite' GUARDIAN It was a tragic day for the nation's wildlife when England's last and loneliest golden eagle died in an unmarked spot among the remote eastern fells of the Lake District. But the fight to restore the landscape had already begun. Lee Schofield, ecologist and site manager for RSPB Haweswater, is leading efforts to breathe life back into two hill farms and their thirty square kilometres of sprawling upland habitat. Informed by the land, its turbulent history and the people who have shaped it, Lee and his team are repairing damaged wetlands, meadows and woods. Each year, the landscape is becoming richer, wilder and better able to withstand the shocks of a changing climate. But in the contested landscape of the Lake District, change is not always welcomed, and success relies on finding a balance between rewilding and respecting cherished farming traditions. This is not only a story of an ecosystem in recovery, it is also the story of Lee's personal connection to place, and the highs and lows of working for nature amid fierce opposition.

The Slender-billed Curlew, Numenius tenuirostris, 'the slim beak of the new moon', is one of the world's rarest birds. It once bred in Siberia and wintered in the Mediterranean basin, passing through the wetlands and estuaries of Italy, Greece, the Balkans and Central Asia. Today the Slender-billed Curlew exists as a rumour, a ghost species surrounded by unconfirmed sightings and speculation. The only certainty is that it now stands on the brink of extinction. Birds are key environmental indicators. Their health or hardship has a message for us about the planet, and our future. What does the fate of the Slender-billed Curlew mean for us, and for the natural world? What happened to it, and why? In Orison for a Curlew Horatio Clare journeys through a fractured Europe in search of the Slender-billed Curlew, following the bird's migratory path on an odyssey that takes us into the lives of the men and women who have fought to save the landscapes to which the bird belongs. This is a story of beauty, triumph, and the struggles of conservation. It is a homage to a bird which may never be seen again.

Lee, Limbani in the blockbuster movie Black Panther 'An excellent read . . . both sobering and uplifting' Moira Smith, General Manager Africa & Middle East, Goway Travel What would drive a man to 'smuggle' rhino horn back into Africa at great risk to himself? This is just one of the situations Grant Fowlds has put himself in as part of his ongoing fight against poaching, in order to prove a link between southern Africa and the illicit, lucrative trade in rhino horn in Vietnam. Shavings of rhino horn are sold as a snake-oil 'cure' for colds or impotence, but a rhino's horn has no magical, medicinal properties. It is for this that rhinoceroses are being killed at an escalating rate that puts the survival of the species in jeopardy. This corrupt, illegal war on wildlife has brought an iconic animal to the brink of extinction. Growing up on a farm in the Eastern Cape of South Africa, Grant developed a deep love of nature, turning his back on hunting to focus on saving wildlife of all kinds and the environment that sustains both them and us. He is a passionate conservationist who puts himself on the front line of protecting rhinos in the wild - right now, against armed poachers; but in the longer term, too, through his work with schoolchildren, communities and policymakers. We are most grateful to photographer Gerhard van der Westhuizen for the use of his stunning photograph on the cover of the book.

R5,679 Discovery Miles 56 790 Ships in 10 - 15 working days

Reef fish spawning aggregations, ranging from small groups to many tens of thousands of individuals, are spectacular but poorly known natural phenomena whereby fish assemble at specific times and locations to spawn. For some species these large groups may be the only form of reproduction, the high fish numbers briefly giving a false impression of stability and abundance-an 'illusion of plenty'. They are often a focus for intensive seasonal fishing because of their predictability and because many important commercial fishes form them. Highly vulnerable to overexploitation, many aggregations and their associated fisheries, have disappeared or are in decline. Few are effectively managed or incorporated into protected areas. Aggregations are not well understood by fishery scientists, managers and conservationists and their significance little appreciated by fishers or the wider public. To ensure their persistence to replenish important fisheries in coral ecosystems, maintain their ecosystem function and continue to delight divers, a significant change in perspective is needed to foster protection and management. This book provides comprehensive and practical coverage of the biology, study and management of reef fish aggregations, exploring their how, when, where, and why. It explores ways to better protect, study, manage and conserve them, while identifying key data gaps and questions. The text is extensively illustrated with many unique, never before published, photographs and graphics. Case studies on over 20 interesting and important fishes are included, outlining their biology and fisheries and highlighting major concerns and challenges.

Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species int- ductions makes them less prone to correction than many other ecological problems. Current reshuffling of species ranges is so great that the present era has been referred to by some as the "Homogocene" in an effort to reflect the unique mag- tude of the changes being made. These alien interlopers often cause considerable ecological and economic d- age where introduced. Species extinctions, food-web disruptions, community alte- tions, ecosystem conversion, changes in nutrient cycling, fisheries collapse, watershed degradation, agricultural loss, building damage, and disease epidemics are among the destructive - and frequently unpredictable - ecological and economic effects that invasive alien species can inflict. The magnitude of these damages c- tinues to grow, with virtually all environments heavily used by humans now do- nated by alien species and many "natural" areas becoming increasingly prone to alien invasion as well. Attention to this problem has increased in the past decade or so, and efforts to prevent or limit further harm are gaining wider scientific and political acceptance.

Diplomacy, Funding and Animal Welfare is a practical guide to the best diplomatic and negotiation practices needed to convince governments and international institutions to effectively protect animals, which also introduces new approaches to fundraising. Animal protection advocates are prepared for speaking to diplomats and government officials in any setting, and to combatants in war zones. The book mainly focuses on approaching local and national governments, the United Nations system, the international Red Cross movement and systems related to other international organizations that can help animals, often in surprising ways. The reader will learn the rules of "diplomatic protocol", and much about the rules and procedures of major international bodies. To provide balance and real world relevance, the guide draws on a compilation of the author's extensive activities across a range of development, animal welfare, emergency management and climate issues in government and in the NGO world, as well as interviews with scholars and officials from NGOs, diplomatic missions, the United Nations, the Red Cross, governments and corporations.

This edited volume addresses a rising concern among natural resource scientists and management professionals about decline of the many plant and animal species associated with early-successional habitats, especially within the Central Hardwood Region of the USA. These open habitats, with herbaceous, shrub, or young forest cover, are disappearing as abandoned farmland, pastures, and cleared forest patches return to forest. There are many questions about "why, what, where, and how" to manage for early successional habitats. In this book, expert scientists and experienced land managers synthesize knowledge and original scientific work to address questions on such topics as wildlife, water, carbon sequestration, natural versus managed disturbance, future scenarios, and sustainable creation and management of early successional habitat in a landscape context.

This volume reviews, for the first time, the broad range of issues that affect the welfare of commercially farmed ratites. Although ratites incorporate several families of flightless birds this book focuses on the most commonly farmed ratites, the ostrich, emu and rhea. The readers are taken on a journey through all sectors of the industry, which include breeding, incubation, hatching, brooding, rearing, growth, transport and processing, with an emphasis on husbandry and management protocols that can impact bird welfare and health. Also discussed is the structure and sensory innervation of the skin and digits of the birds, and the potential welfare implications of industry practices on these structures. Each chapter in this volume focuses on a particular aspect of the commercial farming of ratites with contributing authors from a broad range of disciplines."

Until now, information on mammals in South Asia has never been brought together on a single platform providing all-inclusive knowledge on the subject. This book is the most up-to-date comprehensive resource on the mammalian diversity of South Asia. It offers information on the diversity, distribution and status of 504 species of terrestrial and aquatic mammals found in Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. This work is unique being the first of its kind that deals with diversity and distribution at the subspecies level. The book is divided in to three chapters. Chapter 1 introduces the subject and takes off from the recent works on mammals at the global level, provides an historical perspective on mammal studies in South Asia and concludes with a note on recent phylogenetic changes at supraordinal levels. Chapter 2 summarizes the information on the diversity of South Asian Mammals, provides analysis by country of mammalian diversity (supported by data in tabular form) dealing with species richness, endemism and possibly occurring species, separate analysis for each country with details on endemic and threatened species, extinct mammals, domestic mammals, and finally the IUCN status of mammals with special emphasis on threatened mammals. Chapter 3 is a comprehensive checklist that provides information on each species, including its scientific name, type details, standardized English name, synonyms, subspecies, distribution and comments on taxonomic status. Country-wise listings and analysis of species richness with emphasis on subspecies distribution Most of the analysis is supported by data in tabular forms for better understanding Notes on extinct and domesticated mammals as well as their IUCN Red List Status with criteria for such status A very comprehensive bibliography that would help readers track down specific literature

In this age of climatic and financial uncertainty, it becomes increasingly important to balance the cost, benefits and risk of wildfire management. In the United States, increased wildland fire activity over the last 15 years has resulted in drastic damage and loss of life. An associated rapid increase in fire management costs has consumed higher portions of budgets of public entities involved in wildfire management, challenging their ability to fulfill other responsibilities. Increased public scrutiny highlights the need to improve wildland fire management for cost effectiveness. This book closely examines the development of basic wildfire suppression cost models for the United States and their application to a wide range of settings from informing incident decision making to programmatic review. The book also explores emerging trends in suppression costs and introduces new spatially explicit cost models to account for characteristics of the burned landscape. Finally, it discusses how emerging risk assessment tools can be better informed by integrating management cost models with wildfire simulation models and values at risk. Economics of Wildfire Management is intended for practitioners as a reference guide. Advanced-level students and researchers will also find the book invaluable.

Population ecology has matured to a sophisticated science with astonishing potential for contributing solutions to wildlife conservation and management challenges. And yet, much of the applied power of wildlife population ecology remains untapped because its broad sweep across disparate subfields has been isolated in specialized texts. In this book, L. Scott Mills covers the full spectrum of applied wildlife population ecology, including genomic tools for non-invasive genetic sampling, predation, population projections, climate change and invasive species, harvest modeling, viability analysis, focal species concepts, and analyses of connectivity in fragmented landscapes. With a readable style, analytical rigor, and hundreds of examples drawn from around the world, "Conservation of Wildlife Populations (2nd ed)" provides the conceptual basis for applying population ecology to wildlife conservation decision-making. Although targeting primarily undergraduates and beginning graduate students with some basic training in basic ecology and statistics (in majors that could include wildlife biology, conservation biology, ecology, environmental studies, and biology), the book will also be useful for practitioners in the field who want to find - in one place and with plenty of applied examples - the latest advances in the genetic and demographic aspects of population ecology.Additional resources for this book can be found at: www.wiley.com/go/mills/wildlifepopulations.

This book deals with the role of education in improving animal welfare and reducing animal suffering inflicted by humans. It embraces situations in which humans have direct control over animals or interfere directly with them, but it considers also indirect animal suffering resulting from human activities. Education is regarded in the broad sense of creating awareness and facilitating change. First, consideration is given to a number of specific themes in which education can make an important contribution towards reducing animal suffering, and subsequently an examination is made of a number of interrelated contexts in which education can address the various themes. The considered educational themes are: * animal suffering and sentience that have both scientific and moral aspects * human discrimination against animals known as speciesism and the need for attitudinal change by humans * role and existing limitations of legislation in providing protection to animals * matter of enforcement of animal protection legislation * achievement of reform to improve animal protection by legislative and other means * training of professionals, carers, and users involved with animals to provide better protection* the scope for science to contribute to improved animal protection * animal protection as a regional and international issue

R4,620 Discovery Miles 46 200 Ships in 12 - 19 working days

For centuries, criminologists have looked for scientific ways to study, understand, and ultimately prevent crime. In this volume, a unique offense, poaching, is explored in various contexts to determine what opportunity structures favor this crime and how situational crime prevention may reduce its prevalence. The data sources used range from publically available secondary data about animal populations, to interviews with hunters, to actual law enforcement data collected inside protected areas. Various methods are utilized to look for patterns in poaching behaviour regarding where poachers strike, which species they target and their modus operandi. Collectively, the volume shows that principles of criminal opportunity theory and situational crime prevention are useful for studying and preventing poaching in a variety of contexts. The methods employed by each chapter are easily replicated and meant to stimulate empirical poaching research where data is available. While the theoretical grounding of this volume is drawn from criminology, it is written for a broad audience of academics, practitioners and those interested in wildlife conservation.

As the human population increases and nations become more industrialized, the habitat and water quality required for the survival of fish continues to decline. In addition to these environmental factors, fish populations are directly or potentially affected by harvesting, enhancement programs and introgression with hatchery-propagated or transgenic fish. To our knowledge no other scientific meeting has been assembled to consider the breadth of the problem, to review the technology that is presently available for the preservation of the germ plasm of salmonid stocks and to identify the scientific advances that are required to overcome the problems. Because many salmonids have spawning grounds within the confines of a specific region or county but will spend a large portion of their life cycle within the territorial waters of other countries or in the open ocean, the preservation of unique genes or gene pools in these animals requires international cooperation. This scientific meeting has provided a forum in which to discuss the problems, evaluate the present methods or technology for addressing the problems and suggest new directions or innovations that need to be implemented. During this meeting we limited our discussion to salmonid fishes. However, the general conclusions about the factors that affect the population dynamics of fish stocks and the technical aspects concerning the preservation of germ plasm will be applicable to other fish species.

It presents a new approach to set fish quota based on holistic ecosystem modeling (the CoastWeb-model) and also a plan to optimize a sustainable management of the Baltic Sea including a cost-benefit analysis. This plan accounts for the production of prey and predatory fish under different environmental conditions, professional fishing, recreational fishing and fish cage farm production plus an analysis of associated economic values. Several scenarios and remedial strategies for Baltic Sea management are discussed and an "optimal" strategy motivated and presented, which challenges the HELCOM strategy that was accepted by the Baltic States in November 2007. The strategy advocated in this book would create more than 7000 new jobs, the total value of the fish production would be about 1600 million euro per year plus 1000 million euro per year related to the willingness-to-pay to combat the present conditions in the Baltic Sea. Our strategy would cost about 370 million euro whereas the HELCOM strategy would cost about 3100 million euro per year. The "optimal" strategy is based on a defined goal - that the water clarity in the Gulf of Finland should return to what it was 100 years ago.

R5,629 Discovery Miles 56 290 Ships in 10 - 15 working days

This book provides a synthesis of taxonomic and ecological information on New Zealand s freshwater fish fauna. New Zealand has been isolated in the southwestern Pacific Ocean since it separated from Gondwana during the Cretaceous period, some 80 million years ago. This prolonged geological isolation, combined with the islands very vigorous geological history, impacted by oceanic submergence, tectonic activity, mountain building extreme volcanism, and great climatic variability, create a dynamic scenario within which the New Zealand biota, including its freshwater fishes, have evolved over millions of years. These impacts have contributed to a highly dynamic biological history with undoubted though little understood extinction and vigorous colonisation of the islands fresh water. One of the key elements for understanding the origins and derivations of this fish fauna is that in all groups some or all of the species are diadromous, customarily spending a significant phase of their lives at sea. This has no doubt contributed in an important way the fauna s origins As well, there has been frequent loss of diadromous behaviours leading, to species that have abandoned their sea-migratory behaviours and which now complete their entire lives in fresh water. The distribution patterns reflect these changing habits, with diadromous species being broadly distributed but tending to be lowland in range, whereas the derived, non-diadromous species have narrower ranges, but are often found further inland and at high elevations. This book provides an ecological and historical synthesis of these divergent patterns across New Zealand s geography and history."
