Destruction of habitat is the major cause for loss of
biodiversity including variation in life history and habitat
ecology. Each species and population adapts to its environment,
adaptations visible in morphology, ecology, behaviour, physiology
and genetics. Here, the authors present the population ecology of
Atlantic salmon and brown trout and how it is influenced by the
environment in terms of growth, migration, spawning and
recruitment. Salmonids appeared as freshwater fish some 50 million
years ago. Atlantic salmon and brown trout evolved in the Atlantic
basin, Atlantic salmon in North America and Europe, brown trout in
Europe, Northern Africa and Western Asia. The species live in small
streams as well as large rivers, lakes, estuaries, coastal seas and
oceans, with brown trout better adapted to small streams and less
well adapted to feeding in the ocean than Atlantic salmon. Smolt
and adult sizes and longevity are constrained by habitat conditions
of populations spawning in small streams. Feeding, wintering and
spawning opportunities influence migratory versus resident
lifestyles, while the growth rate influences egg size and number,
age at maturity, reproductive success and longevity. Further, early
experiences influence later performance. For instance, juvenile
behaviour influences adult homing, competition for spawning
habitat, partner finding and predator avoidance.
Large ungulates in tropical forests are among the most threatened taxa of mammals. Excessive hunting, degradation of and encroachments on their natural habitats by humans have contributed to drastic reductions in wild ungulate populations in recent decades. As such, reliable assessments of ungulate-habitat relationships and the spatial dynamics of their populations are urgently needed to provide a scientific basis for conservation efforts. However, such rigorous assessments are methodologically complex and logistically difficult, and consequently many commonly used ungulate population survey methods do not address key problems. As a result of such deficiencies, key parameters related to population distribution, abundance, habitat ecology and management of tropical forest ungulates remain poorly understood. This book addresses this critical knowledge gap by examining how population abundance patterns in five threatened species of large ungulates vary across space in the tropical forests of the Nagarahole-Bandipur reserves in southwestern India. It also explains the development and application of an innovative methodology - spatially explicit line transect sampling - based on an advanced hierarchical modelling under the Bayesian inferential framework, which overcomes common methodological deficiencies in current ungulate surveys. The methods and results presented provide valuable reference material for researchers and professionals involved in studying and managing wild ungulate populations around the globe.
This book critically explores the political ecology of human marginalization, wildlife conservation and the role of the state in politicizing conservation frameworks, drawing on examples from forests in India. The book specifically demonstrates the nuances within human-environmental linkages, by showing how environmental concerns are not only ecological in content but also political. In India a large part of the forests and their surrounding areas were inhabited far before they were designated as protected areas and inviolate zones, with the local population reliant on forests for their survival and livelihoods. Thus, socioecological conflicts between the forest dependents and official state bodies have been widespread. This book uses a political ecology lens to explore the complex interplay between current norms of forest conservation and environmental subjectivities, illustrating contemporary articulation of forest rights and the complex mediations between forest dependents and different state and non-state bodies in designing and implementing regulatory standards for wildlife and forest protection. It foregrounds the issues of identity, migration and cultural politics while discussing the politics of conservation. Through a political ecology approach, the book not only is human-centric but also makes significant use of the role of non-humans in foregrounding the conservation discourse, with a particular focus on tigers. The book will be of great interest to students and academics studying forest conservation, human-wildlife interactions and political ecology.
Snow Leopards: Biodiversity of the World: Conservation from Genes to Landscapes is the only comprehensive work on the biology, behavior, and conservation status of the snow leopard, a species that has long been one of the least studied, and hence poorly understood, of the large cats. Breakthroughs in technologies and methodologies to study this elusive cat have come rapidly, including non-invasive genetics, camera traps, and GPS-satellite collaring. The book begins with chapters on the genetic standing and taxonomy of the snow leopard, followed by chapters on their behavior and ecology. Additional contributions follow on the current and emerging threats to the species, which include longstanding concerns, such as poaching and conflicts with livestock, and new and emerging threats such as mining and climate change. A section on conservation solutions, backed by valuable case studies, starts with an overview of the important role mountain communities play in assuring the snow leopard's long-term persistence. In addition, chapters on the role of captive snow leopards for the conservation of the species, state-of-the-art techniques and technologies for studying and monitoring snow leopards, status reports from around the region, and future perspectives, such as transboundary conservation initiatives, international conventions (CITES, CMS, etc.), the role of the IUCN Cat Specialist Group and the Snow Leopard Network, and undertakings such as the Global Snow Leopard Forum facilitated by the World Bank are also included.
This is the ninth volume of ten in the The Natural History of the Crustacea Series. The chapters in this volume synthesize the diverse topics in fisheries and aquaculture. In the first part of the book, chapters explore worldwide crustacean fisheries. This section comes to a conclusion with two chapters on harvested crustaceans that are usually not within the focus of the mainstream fisheries research, possibly because they are caught by local fishing communities in small-scale operations and sold locally as subsistence activity. In the second part of the book, the authors explore the variety of cultured crustacean species, like shrimps, prawns, lobsters, and crabs. Chapters in the third part of the volume focus on important challenges and opportunities, including diseases and parasitism, the use of crustacean as bioindicators, and their role in biotechnology.
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.
Douglas W. Tallamy's first book, Bringing Nature Home, sparked a national conversation about the link between healthy local ecosystems and human well-being. In his new book Nature's Best Hope, Tallamy takes the next step and outlines his vision for a grassroots approach to conservation. Tallamy advocates for homeowners everywhere to turn their yards into conservation corridors that provide wildlife habitats and mitigate the effects of development and corporate agriculture. This home-based approach doesn't rely on the federal government and protects the environment from the whims of politics. It is also easy to do, and readers will walk away with specific suggestions they can incorporate into their own yards. Nature's Best Hope is nature writing at its best - rooted in history, progressive in its advocacy, and above all, actionable and hopeful. By proposing practical measures that ordinary people easily can do, Tallamy gives us reason to believe that the planet can be preserved for future generations.
Changes in farmland management throughout the twentieth century, including agricultural intensification and increasing mechanisation, have resulted in the loss of habitat for many species. The Corncrake is one such species that has faced multiple challenges to its survival. Although it was once a common bird throughout northern Europe, the breeding areas of Corncrakes have been steadily reduced to a fraction of what they once were, and in many areas their continuation as a regularly breeding bird is in serious doubt. In addition, the behaviour of the Corncrake, nesting under the cover of tall grass and undertaking annual long-distance migrations, means that for most of the last hundred years, its detailed ecology has remained mysterious and little understood. Although there have been millions of words written about the Corncrake in scientific papers, until now there has been no full-length book that attempts to capture all the aspects of its ecology, and to present this information to non-specialists. As a result, until very recently, many important facts about its lifestyle and behaviour have not been widely known, even among ornithologists. Although scarcely seen in its natural habitat, the Corncrake is well-known in many rural areas due to its characteristic (and persistent) night-time calling, but new discoveries with the aid of acoustic science have proved surprising, and may offer new ways of improving the location, identification, and management options to protect and enable the population of this iconic species to recover, even to thrive in our countryside. A new appreciation of the requirements of this species and the ways in which our sensitive management of the whole landscape, both in its potential breeding areas across Europe and Asia and in the seasonal quarters in regions of Africa, offer new hope for the future of this fascinating bird.
Originally published in 1979 International Trade in Wildlife is a product of the 1973 Convention on International Trade in Endangered Species of Wild Fauna and Flora conference, containing the full text of the CITIES convention. The volume outlines the animals and plants controlled by CITIES, and describes the protective policies put in place to protect endangered plants and animals. It gives a detailed background to the international traffic in monkey's, spotted cats, whales, ivory, parrots, tortoises, marine turtles, crocodiles, butterflies, sponges and rare orchids at the time of publication and acts as a comprehensive document on the conservation policies enacted through CITIES, as well as facts surrounding the decline of endangered species. Although published over 40 years ago, the document still offers a comprehensive and useful guide to conservation and will be an important historical document for environmental policy makers and conservationists alike.
This book will provide the state-of-the-art on most of the topics involved in the ecology and conservation of birds of prey.

case studies of successful governance models could be referred to by others in order to improve the management of the sector. This is the initial step toward compiling stories of aquaculture successes, and the editorial team is to be congratulated for its great efforts. In approaching this difficult assignment, the team benefited from the leadership of the Network of Aquaculture Centres for Asia and the Pacific (NACA), and the support of the World Fisheries Trust (WFT) as well as the Institute for International Sustainable Development (IISD) of Canada. We hope that the team will continue its endeavor in producing other aquaculture success stories, also from other regions of the world. Rome, Italy Jiansan Jia Pr eface We are moving into a turbulent and an uncertain era, particularly in respect of the future food needs. Given the push to sustainability, the rise in food prices, and the impending concerns around climate change and related complexity on providing the food needs for an increasing global population, it is time to address coping strategies. It is in this context that the issue on where will aquaculture development move in the future is taken up.
The Atlantic Walrus: Multidisciplinary insights into human-animal interactions addresses the key dimensions of long-term human walrus interactions across the Atlantic Arctic and subarctic regions, over the past millennia. This book brings together research from across the social and natural sciences to explore walrus biology, human culture, environmental conditions and their reciprocal effects. Together, 13 chapters of this book reconstruct the early evolution of walruses, walrus biology, the cultural significance and ecological impact of prehistoric and indigenous hunting practices, as well as the effects of commercial hunting and international trade. This book also examines historic and ongoing management strategies and, the importance of new research methodologies in revealing hitherto unknown details of the past, and concludes by discussing the future for Atlantic walruses in the face of climate change and increased human activities in the Arctic. This volume is an ideal resource for those who are seeking to understand an iconic Arctic species and its long and complex relationship with humans. This includes individuals and researchers with a personal or professional connection to walruses or the Arctic, as well as marine biologists, zoologists, conservationists, paleontologists, archaeologists, anthropologists, historians, indigenous communities, natural resource managers and government agencies.
The oceans cover over 70% of our planet. They are host to a biodiversity of tremendous wealth. Its preservation is now a global priority featuring in several international conventions and a confirmed objective of European policies and national strategies. Understanding the dynamics and the uses of the marine biodiversity is a genuine scientific challenge. Fourteen international experts have got together and identified five priority research themes to address the problem, based on analysing the state of knowledge.
This innovative book integrates practical information from restoration projects around the world with the latest developments in successional theory. It recognizes the critical roles of disturbance ecology, landscape ecology, ecological assembly, invasion biology, ecosystem health, and historical ecology in habitat restoration. It argues that restoration within a successional context will best utilize the lessons from each of these disciplines.

Beginning with an overview of data and concepts developed in the EU-project HABIT-CHANGE, this book addresses the need for sharing knowledge and experience in the field of biodiversity conservation and climate change. There is an urgent need to build capacity in protected areas to monitor, assess, manage and report the effects of climate change and their interaction with other pressures. The contributors identify barriers to the adaptation of conservation management, such as the mismatch between planning reality and the decision context at site level. Short and vivid descriptions of case studies, drawn from investigation areas all over Central and Eastern Europe, illustrate both the local impacts of climate change and their consequences for future management. These focus on ecosystems most vulnerable to changes in climatic conditions, including alpine areas, wetlands, forests, lowland grasslands and coastal areas. The case studies demonstrate the application of adaptation strategies in protected areas like National Parks, Biosphere Reserves and Natural Parks, and reflect the potential benefits as well as existing obstacles. A general section provides the necessary background information on climate trends and their effects on abiotic and biotic components. Often, the parties to policy change and conservation management, including managers, land users and stakeholders, lack both expertise and incentives to undertake adaptation activities. The authors recognise that achieving the needed changes in behavior - habit - is as much a social learning process as a matter of science-based procedure. They describe the implementation of modeling, impact assessment and monitoring of climate conditions, and show how the results can support efforts to increase stakeholder involvement in local adaptation strategies. The book concludes by pointing out the need for more work to communicate the cross-sectoral nature of biodiversity protection, the value of well-informed planning in the long-term process of adaptation, the definition of acceptable change, and the motivational value of exchanging experience and examples of good practice.
The 40 or so species of beach-loving plovers (genus Charadrius) comprise a diverse group of shorebirds found around the world. Most of these species are challenged by changing climates and other human-related development activities, yet they provide key insights into basic ecological and evolutionary processes. The expert international contributors take a comparative approach, presenting examples from many worldwide plover studies and synthesizing the group's most pressing and important topics. The book further presents an emphasis on full life-cycle biology, including the importance of examining migratory connectivity issues, even for non-migratory plovers.

The proposed book focuses on one of the most important issues affecting humankind in this century - Peak Oil or the declining availability of abundant, cheap energy-and its effects on our industrialized economy and wildlife conservation. Energy will be one of the defining issues of the 21st Century directly affecting wildlife conservation wherever energy extraction is a primary economic activity and indirectly through deepening economic recessions. Since cheap, abundant energy has been at the core of our industrial society, and has resulted in the technological advancements we enjoy today, the peak in world oil extraction would potentially have major impacts on civilization unless we prepare well in advance. One potential economic solution covered in the book would be a Steady State Economy with a stable population and per capita consumption, particularly in such industrialized countries as the United States. Furthermore, the lack of cheap, abundant energy directly and indirectly affects conservation efforts by professional societies and federal and state agencies, and NGOs concerned with wildlife issues. We need to recognize these potential problems and prepare, as much as possible, for the consequences stemming from them.
"In this brilliant study of cloned wild life, Carrie Friese adds a whole new dimension to the study of reproduction, illustrating vividly and persuasively how social and biological reproduction are inextricably bound together, and why this matters."--Sarah Franklin, author of Dolly Mixtures: the Remaking of Genealogy The natural world is marked by an ever-increasing loss of varied habitats, a growing number of species extinctions, and a full range of new kinds of dilemmas posed by global warming. At the same time, humans are also working to actively shape this natural world through contemporary bioscience and biotechnology. In Cloning Wild Life, Carrie Friese posits that cloned endangered animals in zoos sit at the apex of these two trends, as humans seek a scientific solution to environmental crisis. Often fraught with controversy, cloning technologies, Friese argues, significantly affect our conceptualizations of and engagements with wildlife and nature. By studying animals at different locations, Friese explores the human practices surrounding the cloning of endangered animals. She visits zoos--the San Diego Zoological Park, the Audubon Center in New Orleans, and the Zoological Society of London--to see cloning and related practices in action, as well as attending academic and medical conferences and interviewing scientists, conservationists, and zookeepers involved in cloning. Ultimately, she concludes that the act of recalibrating nature through science is what most disturbs us about cloning animals in captivity, revealing that debates over cloning become, in the end, a site of political struggle between different human groups. Moreover, Friese explores the implications of the social role that animals at the zoo play in the first place--how they are viewed, consumed, and used by humans for our own needs. A unique study uniting sociology and the study of science and technology, Cloning Wild Life demonstrates just how much bioscience reproduces and changes our ideas about the meaning of life itself. Carrie Friese is Lecturer in Sociology at the London School of Economics and Political Science.

The Natura 2000 network of protected areas is the centrepiece of European Union nature policy, currently covering almost one-fifth of the EU's entire land territory plus large marine areas. This vast EU-wide network, which aims to conserve Europe's most valuable and threatened species and habitats, has major impacts on land use throughout all Member States of the EU. This book critically assesses the origins and implementation of the Natura 2000 network, established under the Birds Directive of 1979 and the Habitats Directive of 1992. Based on original archival research and interviews with key participants, the book records a detailed history of the origins and negotiation of Natura 2000 policy and law, with the history of EU environmental policy provided as a framework. An historical institutionalist approach is adopted, which emphasises the importance of understanding legal and policy development as processes that unfold over time. Three phases in the history of EU environmental policy are identified and described, and the history of EU nature policy is placed within the context of these three phases. Informed by this history, the author presents a comprehensive summary and assessment of the law and policy that protects Natura 2000 sites at EU level, and reviews the nature conservation outcomes for the targeted species and habitats. The book reveals how a knowledge of the history of Natura 2000 enriches our understanding of key issues such as conflicts in establishing and conserving the Natura 2000 network, EU integration in the field of nature conservation, and the future of EU nature policy.
A concise but comprehensive introduction to the biology of standing waters (lakes and ponds). As with other books in the Biology of Habitats Series, the emphasis in this book is on the organisms that dominate freshwater environments. Management and conservation aspects are also considered. The first edition of the book published in 1998 with a second, revised edition in 2005. There has been significant development in the field since the last revision appeared, particularly in the ecology of lakes and ponds in subtropical and tropical areas, and a new revision of this now classic text is timely.
This book provides both the conceptual basis and technological tools that are necessary to identify and solve problems related to biodiversity governance. The authors discuss intriguing evolutionary questions, which involve the sometimes surprising adaptive capacity of certain organisms to dwell in altered and/or changing environments that apparently lost most of their structure and functionality. Space and time heterogeneities are considered in order to understand the patterns of distribution and abundance of species and the various processes that mold them. The book also discusses at which level from genes to the landscape, including individuals, populations, communities, and ecosystems men should intervene in nature in order to prevent the loss of biodiversity."
Conservationist Grant Fowlds lives to save and protect Africa's rhinos, elephants and other iconic wildlife, to preserve their habitats, to increase their range and bring back the animals where they have been decimated by decades of war, as in Angola, Mozambique and the Democratic Republic of the Congo. This vivid account of his work tells of a fellow conservationist tragically killed by the elephants he was seeking to save and a face-off with poachers, impoverished rural people exploited by rapacious local businessmen. Fowlds describes the impact of the Covid pandemic on conservation efforts, the vital wildlife tourism that sustains these and rural communities; and tells of conservationists' efforts to support people through the crisis. Lockdowns may have brought a welcome lull in rhino and other poaching, but also brought precious tourism to a standstill. He shows how the pandemic has highlighted the danger to the world of the illicit trade in endangered wildlife, some of it sold in 'wet markets', where pathogens incubate and spread. He describes a restoration project of apartheid-era, ex-South African soldiers seeking to make reparations in Angola, engulfed for many years in a profoundly damaging civil war, which drew in outside forces, from Cuba, Russia and South Africa, with a catastophic impact on that country's wildlife. Those who fund conservation, whether in the US, Zambia or South Africa itself, are of vital importance to efforts to conserve and rewild: some supposed angel-investors turn out to be not what they had appeared, some are thwarted in their efforts, but others are open-hearted and generous in the extreme, which makes their sudden, unexpected death an even greater tragedy. A passionate desire to conserve nature has also brought conservationists previously active in far-off Venezuela to southern Africa. Fowlds describes fraught meetings to negotiate the coexistence of wildlife and rural communities. There are vivid accounts of the skilled and dangerous work of using helicopters to keep wildebeest, carrying disease, and cattle apart, and to keep elephants from damaging communal land and eating crops such as sugar cane. He tells of a project to restore Africa's previously vast herds of elephants, particularly the famed 'tuskers', with their unusually large tusks, once prized and hunted almost to extinction. The range expansion that this entails is key to enabling Africa's iconic wildlife to survive, to preserving its wilderness and, in turn, helping humankind to survive. There is a heartening look at conservation efforts in Mozambique, a country scarred by years of war, which are starting to bear fruit, though just as a new ISIS insurgency creates havoc in the north of the country. What will humanity's relationship with nature be post-pandemic? Will we have begun to learn that by conserving iconic wildlife and their habitats we help to preserve and restore precious pockets of wilderness, which are so vital not only the survival of wildlife, but to our own survival on our one precious planet. |
