Rangeland ecosystems which include unimproved grasslands, shrublands, savannas and semi-deserts, support half of the world's livestock, while also providing habitats for some of the most charismatic of wildlife species. This book examines the pressures on rangeland ecosystems worldwide from human land use, over-hunting, and subsistence and commercial farming of livestock and crops. Leading experts have pooled their experiences from all continents to cover the ecological, sociological, political, veterinary, and economic aspects of rangeland management today. This book provides practitioners and students of rangeland management and wildland conservation with a diversity of perspectives on a central question: can rangelands be wildlands? * The first book to examine rangelands from a conservation perspective* Emphasizes the balance between the needs of people and livestock, and wildlife* Written by an international team of experts covering all geographical regions* Examines ecological, sociological, political, veterinary, and economic aspects of rangeland management and wildland conservation, providing a diversity of perspectives not seen before in a single volume

Along a tiny spring in a narrow canyon near Death Valley, seemingly against all odds, an Inyo Mountain slender salamander makes its home. "The desert," writes conservation biologist Christopher Norment, "is defined by the absence of water, and yet in the desert there is water enough, if you live properly." Relicts of a Beautiful Sea explores the existence of rare, unexpected, and sublime desert creatures such as the black toad and four pupfishes unique to the desert West. All are anomalies: amphibians and fish, dependent upon aquatic habitats, yet living in one of the driest places on earth, where precipitation averages less than four inches per year. In this climate of extremes, beset by conflicts over water rights, each species illustrates the work of natural selection and the importance of conservation. This is also a story of persistence - for as much as ten million years - amid the changing landscape of western North America. By telling the story of these creatures, Norment illustrates the beauty of evolution and explores ethical and practical issues of conservation: what is a four-inch-long salamander worth, hidden away in the heat-blasted canyons of the Inyo Mountains, and what would the cost of its extinction be? What is any lonely and besieged species worth, and why should we care?

In the past decade, wildlife trafficking -- the poaching or other taking of protected or managed species and the illegal trade in wildlife and their related parts and products -- has escalated into an international crisis. Wildlife trafficking is both a critical conservation concern and a threat to global security with significant effects on the national interests of the United States and the interests of our partners around the world. As President Obama said in Tanzania in July 2013, on issuing a new Executive Order to better organise United States Government efforts in the fight against wildlife trafficking, wildlife is inseparable from the identity and prosperity of the world as we know it. We need to act now to reverse the effects of wildlife trafficking on animal populations before we lose the opportunity to prevent the extinction of iconic animals like elephants and rhinoceroses. Like other forms of illicit trade, wildlife trafficking undermines security across nations. Well-armed networks of poachers, criminals, and corrupt officials exploit porous borders and weak institutions to profit from trading in illegally taken wildlife. This book discusses national strategy, implementation plans, and restrictions on elephant ivory trade.

Despite sporadic news coverage of extreme weather events, high-level climate change diplomacy, special UN days of celebration, and popular media references to impending ecological collapse, most students are not exposed to the detailed presentation and analysis of the international relations and diplomacy of environmental policy-making. Comprehensive and accessibly written for first-year or second-year undergraduates, the second edition of Global Ecopolitics provides students with a panoramic view of the policymakers and the structuring bodies involved in the creation of environmental policies. Detailing a considerable amount of environmental activity since its initial 2012 publication, this up-to-date second edition uses an applicable framework of systemic analysis and important case studies that push students to form their own conclusions about past efforts, present needs, and future directions.

In 2011, adventurer and conservationist John Davis Walked, cycled, skied, canoed, and kayaked on an epic 10-month, 7,600-mile journey that took him from the keys of Florida to a remote seashore in northeastern Quebec. Davis was motivated by a dream: to see a continent-long corridor conserved for wildlife in the eastern United States, especially for the large carnivores so critical to the health of the land. In Big, Wild, and Connected, we travel the Eastern Wildway with Davis, viscerally experiencing the challenges Iarge carnivores, with their need for vast territories, face in an ongoing search for food, water, shelter, and mates. On his self-propelled journey, Davis explores the wetlands, forests, and peaks that are the last strongholds for wildlife in the East. This includes strategically important segments of disturbed landscapes, from longleaf pine savanna in the Florida Panhandle to road-latticed woods of Pennsylvania. Despite the challenges, Davis argues that creation of an Eastern Wildway is within our reach and would serve as a powerful symbol of our natural and cultural heritage. Big, Wild, and Connected reveals Eastern landscapes through wild eyes, a reminder that, for the creatures with which we share the land, movement is as essential to life as air, Water, and food. Davis' journey shows that a big, wild, and connected network of untamed places is the surest way to ensure wildlife survival through the coming Centuries.

In New Mexico's Gila Wilderness, 83 Mexican gray wolves may be some of the most monitored wildlife on the planet. Collared, microchipped, and transported by helicopter, the wolves are protected and confined in an attempt to appease ranchers and conservationists alike. Once a symbol of the wild, these wolves have come to illustrate the demise of wilderness in this Human Age, where man's efforts shape life in even the most remote corners of the earth. And yet, the howl of an unregistered wolf, half of a rogue pair, splits the night. If you know where to look, you'll find that much remains untamed, and even today, wildness can remain a touchstone for our relationship with the rest of nature. In Satellites in the High Country, journalist and adventurer Jason Mark travels beyond the bright lights and certainties of our cities to seek wildness wherever it survives. In California's Point Reyes National Seashore, a battle over oyster farming and designated wilderness pits former allies against one another, as locals wonder whether wilderness should be untouched, farmed, or something in between. In Washington's Cascade Mountains, a modern-day wild woman and her students learn to tan hides and start fires without matches, attempting to connect with a primal past out of reach for the rest of society. And in Colorado's High Country, dark skies and clear air reveal a breathtaking expanse of stars, flawed only by the arc of a satellite passing - beauty interrupted by the traffic of a million conversations. These expeditions to the edges of civilization's grid show us that, although our notions of pristine nature may be shattering, the mystery of the wild still exists, and in fact, it is more crucial than ever. But wildness is wily as a coyote: you have to be willing to track it to understand the least thing about it. Satellites in the High Country is an epic journey on the trail of the wild, a poetic and incisive exploration of its meaning and enduring power in our Human Age.

Before commercial whaling was outlawed in the 1980s, diplomats, scientists, bureaucrats, environmentalists, and sometimes even whalers themselves had attempted to create an international regulatory framework that would allow for a sustainable whaling industry. In Whales and Nations, Kurkpatrick Dorsey tells the story of the international negotiation, scientific research, and industrial development behind these efforts -and their ultimate failure. Whales and Nations begins in the early twentieth century, when new technology revived the fading whaling industry and made whale hunting possible on an unprecedented scale. By the 1920s, declining whale populations prompted efforts to develop "rational"-what today would be called sustainable-whaling practices. But even though almost everyone involved with commercial whaling knew that the industry was on an unsustainable path, Dorsey argues, powerful economic, political, and scientific forces made failure nearly inevitable. Based on a deep engagement with diplomatic history, Whales and Nations provides a unique perspective on the challenges facing international conservation projects. This history has profound implications for today's pressing questions of global environmental cooperation and sustainability. Watch the trailer: http://www.youtube.com/watch?v=3QsLlM5KTx0

"Conservation of Tropical Birds" has been written by four conservation biologists whose expertise spans all the tropical regions of the world. It is the first book to cover all the major issues in tropical bird conservation. Current problems faced by tropical bird conservationists are summarised and potential solutions outlined based on the results of case studies.

Birds are key indicators of ecosystem health, and such a well-studied group of organisms, that they provide an excellent lens through which to examine global conservation problems caused by phenomena such as climate change, declines in ecosystem services, habitat loss, fires, overexploitation, and invasive species. Therefore, the book also provides an engaging synopsis of the general issues in conservation and the problems faced by other wildlife.

This book serves as an important resource and companion to all people interested in observing and conserving birds in the tropics and elsewhere.

This book summarises legal and political events related to active sonar and marine mammals. While strandings and mortality of marine mammals, primarily beaked whales, have been observed in concurrence with mid-frequency sonar operation, additional controversy has focused on the development of low-frequency active (LFA) sonar. Some peacetime use of military sonar has been regulated under the Marine Mammal Protection Act (MMPA) and other statutes due to concerns that active military sonars are operated at frequencies used by some cetaceans (i.e., whales, porpoises, and dolphins), and their high-intensity sound pulses may travel long distances in the ocean. Although mid-frequency sonar has been implicated in several beaked whale strandings, there is scientific uncertainty surrounding the totality of the effects active sonar transmissions may have on marine mammals. This book also addresses the concern regarding environmental effects of ocean noise on three activities -- military sonar exercises, oil and gas exploration, and commercial shipping. This is an edited, excerpted and augmented edition of a CRS publication.

The study of primate ecology and conservation has advanced rapidly in recent years. This practical volume brings together a group of distinguished primate researchers to synthesize field, laboratory, and conservation management techniques for primate ecology and conservation. The synthesis focuses on new and emerging field methods alongside a comprehensive presentation of laboratory and data analysis techniques, as well as the latest methods for determining conservation status and conservation management. This book's particular focus is on innovative ways to study primates in a changing world, including emerging methods such as non-invasive genetic techniques and advanced spatial modeling. In addition to synthesizing field and lab methods, the authors also discuss data interpretation, as well as important guiding questions and principles for students and researchers to consider as they plan research projects in primate ecology and conservation such as: how to choose a field site, acquire research permits, connect with local authorities, communities and researchers, and many other considerations. Although three chapters are dedicated to conservation methods, consideration of conservation status and threats to primate populations are considered throughout this volume where appropriate. This latest publication in the Techniques in Ecology and Conservation Series aims to provide a practical empirical reference text with an international scope, appropriate for graduate students, researchers, and conservation professionals across the globe.

Rescuing wild animals in distress requires a unique set of skills, very different from those used in handling domestic animals. The equipment, degree of handling, the type of caging and level of care a wild animal receives can mean the difference between life and death. "Wildlife Search and Rescue" is a comprehensive guide on 'best practices' and suggested standards for response to sick, injured and orphaned wildlife. This valuable resource covers the fundamentals of wildlife rescue, from 'phone to field', including safe and successful capture strategies, handling and restraint techniques and initial aid. "Wildlife Search and Rescue" is a must have for anyone interested in knowing what to do when they are face to face with a wild animal in need, or for anyone involved in animal rescue. While the book focuses on wildlife native to North America, much of the information and many of the techniques are applicable to other species, including domestic dogs and cats.

This book compiles the latest findings in the field of marine and brackishwater aquaculture. It covers significant topics such as techniques of culture of live feeds (microalgae, rotifer, Artemia, marine copepod & polychaetes), while also highlighting vital themes like the culture and applications of free and marine sponge associated microbial probiotics, controlled breeding, seed production and culture of commercially important fin and shell fishes. Moreover, the book focuses on the breeding and culture of marine ornamental fishes, sea cucumber and sea urchin and discusses seaweeds culture, aqua feed formulation and nutrition, water quality management in hatchery and grow-out culture systems, fish disease diagnosis and health management and cryopreservation of fish gametes for sustainable aquaculture practices, all from a multidimensional perspective. The global fish production was 154 million tonnes in 2011 which more or less consisted of capture and culture fisheries (FAO, 2012). Roughly 80% of this is from inland-freshwater aquaculture and the remainder from capture fisheries in the marine and brackishwater sector. However, marine and brackishwater catches have recently begun to diminish due to overexploitation, climate change and pollution. The UNEP report affirmed that if the world remains on its current course of overfishing, by 2050, the ocean fish stock could become extinct or no longer commercially viable to exploit. In these circumstances, aquaculture is considered to be a promising sector to fulfill our future protein requirement. However, brackishwater and marine fish production now face serious challenges due to e.g. lack of quality fish seeds, feeds, poor water quality management and diseases. Fisheries and aquaculture sectors play a vital role as potential sources of nutritional security and food safety around the globe. Fish food is rich in protein, vitamins, phosphorous, calcium, zinc, selenium etc. In addition, fish contains omega-3 fatty acids, which help to prevent cardiovascular diseases. Fish food can also provide several health benefits to consumers. The omega 3 fatty acids found in fish can reduce the levels of LDL cholesterol (the "bad" cholesterol) and increase the HDL levels (the "good" cholesterol). Research conducted in Australia has proved that fish consumption can be used to cure hypertension and obesity. It is also reported that people who ate more fish were less prone to asthma and were able to breathe more easily. Omega 3 fish oil or fish consumption can help to prevent three of the most common forms of cancer: breast cancer, colon and prostate cancer. The omega 3 fatty acids present in fish or fish oil induce faster hair growth and prevent hair loss. Since most varieties of fish are rich in protein, eating fish helps to keep hair healthy. Furthermore, fish or fish oil helps in improving the condition of dry skin, giving it a healthy glow. It is useful in treating various skin problems such as eczema, psoriasis, itching, redness of skin, skin lesions and rashes. It is well known that eating fish improves vision and prevents Alzheimer's and type-2 diabetes, and can combat arthritis. Further, fish oil or fish is good for pregnant women, as the DHA present in it helps in the development of the baby's eyes and brain. It helps to avoid premature births, low birth weights and miscarriages. In addition, it is widely known that fish can be a good substitute for pulses in cereal-based diets for the poor. The global fish production was roughly 154 million tonnes in 2011 (FAO, 2012). It is estimated that by 2020 global fish requirements will be over 200 million tonnes; as such, innovative technological improvements are called for in order to improve the production and productivity in fisheries. In this context, this book provides valuable information for academics, scientists, researchers, government officials and farmers on innovative technological advances for sustainable fish production using aquaculture methods. The book identifies the main issues and trends in marine and brackishwater aquaculture from a global perspective in general and in the Indian context in particular. It includes 23 chapters written by prominent researchers from various institutes and universities across India, who address the latest aquaculture technologies with distinctive approaches to support academics, researchers and graduates in the fields of Fisheries, Aquaculture, Marine Science, Marine Biology, Marine Biotechnology, Zoology and Agricultural Sciences. Our thanks go to our contributors; we are confident that all readers will immensely benefit from their valued expertise in the field of marine and brackishwater aquaculture.

R2,707 Discovery Miles 27 070 Ships in 7 - 11 working days

This book is about the ongoing transition of fisheries governance, from top-down command and control towards a more transparent and participatory form. It focuses on the emergence of research practices and advice frameworks that allow co-creation of common knowledge bases for management. Drawing from 8 years of research in GAP, a two-stage 7th framework EU project, the book offers a critical examination of how knowledge practices in fisheries governance are changing. The entry point for this research is a series of practical experiments in the unchartered terrain of collaborative research. To gain insight into the ongoing transition in European fisheries management, GAP initiated and carried out 13 Case Studies in different settings across Europe. In each case study, a team of fishers and marine scientists worked together to identify, plan and implement research projects intended to make a difference. The cases vary. They take on different management issues and shape the collaborations in different ways. The extent to which they succeed in realizing their objectives also differs. They are all contributing important insights into the possibilities of co-creating knowledge for management purposes. The book delves into the individual experiences of each case study as well as the lessons they contribute as a whole. The examination concludes that while research partnerships are not always easy to establish, they are an important step towards better fisheries governance. Without a common knowledge base for fisheries governance, co-created through collaborative research practices, sustainable fisheries will remain out of reach.

This book discusses the findings of research on the human dimensions of wildlife management conducted in Japan, demonstrating how such research and approaches have contributed to mitigating human-wildlife conflicts. Human-wildlife conflicts, including agricultural and property damage as well as occasional casualties, are a global problem for which local residents, managers, and stakeholders around the world are struggling to find solutions. Human dimensions of wildlife management (HDW) is an academic field developed in North America in the 1970s to gather information on the social aspects of human-wildlife issues to help wildlife managers and stakeholders implement effective decision-making measures. However, HDW is not widely recognized or applied outside North America, and few studies have investigated whether HDW approaches would be effective in different cultural settings.This is the first book written in English to introduce the HDW theories and practices implemented in Asia. Presenting innovative approaches and research techniques, as well as tips on how to introduce HDW methods into culturally different societies, it is a valuable resource not only for researchers and students in this field, but also for government officials/managers, NGOs, residents and other stakeholders who are affected by human-wildlife conflicts around the globe.

Does extinction have to be forever? As the global extinction crisis accelerates, conservationists and policy-makers increasingly use advanced biotechnologies such as reproductive cloning, polymerase chain reaction (PCR) and bioinformatics in the urgent effort to save species. Mendel's Ark considers the ethical, cultural and social implications of using these tools for wildlife conservation. Drawing upon sources ranging from science to science fiction, it focuses on the stories we tell about extinction and the meanings we ascribe to nature and technology. The use of biotechnology in conservation is redrawing the boundaries between animals and machines, nature and artifacts, and life and death. The new rhetoric and practice of de-extinction will thus have significant repercussions for wilderness and for society. The degree to which we engage collectively with both the prosaic and the fantastic aspects of biotechnological conservation will shape the boundaries and ethics of our desire to restore lost worlds.

The sustainable exploitation of the marine environment depends upon our capacity to develop systems of management with predictable outcomes. Unfortunately, marine ecosystems are highly dynamic and this property could conflict with the objective of sustainable exploitation. This book investigates the theory that the population and behavioural dynamics of predators at the upper end of marine food chains can be used to assist with management. Since these species integrate the dynamics of marine ecosystems across a wide range of spatial and temporal scales, they offer new sources of information that can be formally used in setting management objectives. This book examines the current advances in the understanding of the ecology of marine predators and will investigate how information from these species could be used in management.

This is the first English book to address the current development of closed recirculating aquaculture systems (cRASs) in Japan, and its implications for industry in the near future. It offers an introduction to the topic and discusses the industrial application of cRASs. Around Europe, cRASs using freshwater have been developed, but to date there is little information about cRASs using the saltwater. As such, the book introduces the technical development of cRASs using the saltwater in Japan and describes measures necessary for their industrialization. It also discusses in detail various species, e.g., flounder, pejerrey, kuruma shrimp, white shrimp and abalone, which have been raised in cRASs. Furthermore, it presents wide topics concerning the technological development of aquariums, an area in which progressive Japanese techniques dominate. Lastly, the book also examines CERAS and poly-culture in Japan. The book is a valuable resource for a wide readership, such as local government officers, energy-industry staff, maintenance and system engineers, as well as those from the construction, agriculture and fishery industries.

"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 ofDolly Mixtures: the Remaking of GenealogyThe 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. InCloning 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 Lifedemonstrates 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.

What other readers are saying about Journeys in the Wild: 'It's touching, it's thought provoking and its emotional...Go pick it up. It's an absolute inspiration of a book.' Goodreads 'Full of unbelievable anecdotes from decades of work, some absolutely hilarious, this book left me in complete wonder.' Goodreads 'An amazing read and I would heartily recommend it to everyone I know.' Goodreads

Emphasizing management and conservation, this book provides a synthesis of the literature on the role of forest mammals in community structure and function in the coniferous forests of western North America. In addition to coverage of some of the charismatic megafauna such as grizzly bears, gray wolves, mountain lions, elk and moose, it also includes small terrestrial mammals, arboreal rodents, bats, medium-sized carnivores, and ungulates. The unique blend of theoretical and practical concepts makes this volume equally suitable for managers, educators, and research biologists.
