Pollution doesn't make for easy sonnets or flowing, romantic narratives. And that's what this title is about - pollution. Not the everyday sort of pollution that we recognise so easily, the type which piles up into stinking heaps of litter or that clogs the sky with filthy smoke. No, this is a form of pollution which is so subtle and insidious that many people do not realise it is there. Invaded is about biological pollution, the kind that comes in dense hedges of lush greenery, blooming fields of heady petals or gracefully draped creepers. It may spread incognito on the wings of a bird, tug on the end of an angler's line or scurry unnoticed through the undergrowth. These pages explore plants and animals that have traversed the borders and boundaries of their natural habitats and made their way into South Africa over the past 300 years and more. Unhindered by the predators and diseases which once kept their populations in check, many have come to outnumber and out-compete the species they encounter in their adopted homes. Invaded provides an overview of the different species that have arrived in our country during the past three centuries, and the threats they pose (or have the potential to become). Ultimately, the book attempts to quantify how these species have changed systems, disrupted the natural environment and threatened the future of the country's many unique plants, animals and habitats.

This timely book discusses various international norms that qualify the right, which all states have, to access and exploit living resources in marine areas beyond national jurisdiction, in order to promote the conservation of such species.It highlights current trends and developments which aim at better coherence, and discusses legal techniques that could serve to harmonize both the objectives of these international norms and their scope of applicability. The author also demonstrates that in some cases, gaps and conflicts in the existing legal framework cannot be simply 'interpreted away' but require the further development of international law in order to be resolved.

R324 Discovery Miles 3 240 Ships in 12 - 17 working days

"A rewarding and enriching fusion of traditional wisdom, science and first-hand experience." -Tristan Gooley, author of The Natural Navigator, and How to Read Nature Drawing from a similar lifestyle and environmental ethic as Henry D. Thoreau and Aldo Leopold, Babcock has lived more than two decades off-grid deep in the forest near the headwaters of the Mississippi River. Here he has discovered a balance in the interconnectedness of all life in the woods, and derived his sustenance from hunting, fishing, gardening, gathering wild food, providing water from a hand-pump well and minimal electricity from the sun. He befriended an Ojibwe Elder, Chi-Ma'iingan (Big Wolf), from whom he learned the Seven Grandfather Teachings (Wisdom, Love, Respect, Courage, Honesty, Humility, and Truth). Each of these seven teachings are represented by an animal. In this collection, Babcock shares his love of the natural world through a unique land ethic that combines the ideology of Thoreau and Leopold, and that which he learned from Chi-Ma'iingan. Babcock proposes a radical shift in how Americans support our environment and wildlife. He was recently featured in the documentary films: MEDICINE OF THE WOLF, and WOLF SPIRIT. From these pages: "We must stop seeing the natural world as a commodity and start seeing it as we would see a family member-something to love, protect, care for, and cherish."

R7,021 Discovery Miles 70 210 Ships in 12 - 17 working days

This book focuses on the ecological impacts of the Great East Japan Earthquake and resulting tsunamis, a rare and extremely large disturbance event, on various coastal ecosystems in Japan's Tohoku area, including sub-tidal and tidal animal communities, sand dune plant communities and coastal forests. The studies presented here describe not only how species and populations in these ecosystems were disturbed by the earthquake and tsunamis, but also how the communities have responded to the event and what types of anthropogenic activities will hamper their recovery processes. In the ecological sciences, it is often argued that large disturbances are critical to shaping community structures and biodiversity in local and regional habitats. However, our understanding of these roles remains limited, simply because there have been few opportunities to examine and address the ecological impacts of large disturbance events. The scale of the 2011 Great East Japan Earthquake makes it one of the largest hazards in the past 1000 years. Thus, this book provides a unique opportunity to advance our understanding of the ecological impacts of large and rare disturbances and the implications of these events in the conservation and management of coastal ecosystems. Following an outline of the Great East Japan Earthquake, the book's content is divided into two major parts. Part I reports on studies examining the ecological impacts of the tsunamis on sub-tidal and tidal animal communities, while Part II focuses on terrestrial plant communities in Japan's coastal Tohoku area. This book will benefit all scientists interested in the ecological impacts of large disturbances on aquatic and terrestrial ecosystems in general, and especially those who are interested in the ecological management of coastal ecosystems and Ecosystem based Disaster Risk Reduction (EcoDRR).

This book provides cutting-edge studies and technologies using small fishes, including zebrafish, medaka, and other fishes as new model animals for molecular biology, developmental biology, and medicine. It also introduces eccentric fish models that are pioneering new frontiers of biology. Zebrafish and medaka have been developed as lower vertebrate model organisms because these small fish are easy to raise in the laboratory and are useful for the live imaging of the morphology and activity of cells and tissues in intact animals. By virtue of those specific advantages, fish studies have demonstrated the common features of vertebrates and raised further questions toward understanding the mystery of life. The book consists of four parts: "Development and Cell Biology", "Homeostasis and Reproduction", "Clinical Models", and "Eccentric Fish". Together they describes the core area of small fish study - often considered mere zoology but which is actually proving to be the universal basis of life. Written by leading scientists, the book helps readers to understand small fishes, inspires scientists to utilize small fishes in their studies, and encourages anyone who wants to participate in the large and fantastic world of small fish.

Andrew L.R. Jackson
R1,251 Discovery Miles 12 510 Ships in 12 - 17 working days

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.

Essam Yassin Mohammed
R1,364 Discovery Miles 13 640 Ships in 12 - 17 working days

Marine and coastal resources provide millions of people with their livelihoods, such as fishing and tourism, and a range of critical additional 'ecosystem services', from biodiversity and culture to carbon storage and flood protection. Yet across the world, these resources are fast-diminishing under the weight of pollution, land clearance, coastal development, overfishing, natural disasters and climate change. This book shows how economic instruments can be used to incentivize the conservation of marine and coastal resources. It is shown that traditional approaches to halt the decline focus on regulating against destructive practices, but to little effect. A more successful strategy could be to establish schemes such as payments for ecosystem services (PES), or incorporate an element of financial incentives into existing regulatory mechanisms. Examples, both terrestrial and marine, from across the world suggest that PES can work to protect both livelihoods and environments. But to succeed, it is shown that these schemes must be underpinned by robust research, clear property rights, sound governance structures, equitable benefit sharing, and sustainable finance. Case studies are included from south and east Asia, Latin America, Africa and Australia. The book explores the prospects and challenges, and draws lessons from PES and PES-like programmes from across the globe.

Ivory is big business, and in some parts of Africa elephants have been hunted almost to extinction in the quest for it. The losses to African economies have been catastrophic. Now there is an international ban on the trade and conservation is. the principal goal. This should be a matter for rejoicing, but nothing is quite so simple. The authors of this book have looked at the overall statistics, including those for countries where the elephant population is stable. They have considered the multiplicity of economic and social functions fulfilled by ensuring that elephant herds survive, tourism, a variety of ecological purpose. and, finally, as a source of ivory. They show how the careful management of elephants as a resource can best serve African interests. This book is at the cutting edge of economic thinking and provides a model for the consideration of the difficult relationship between people and wildlife. Originally published in 19990

From cocoa farming in Ghana to the orchards of Kent and the desert badlands of Pakistan, taking a practical approach to sustaining the landscape can mean the difference between prosperity and ruin. Working with Nature is the story of a lifetime of work, often in extreme environments, to harvest nature and protect it - in effect, gardening on a global scale. It is also a memoir of encounters with larger-than-life characters such as William Bunting, the gun-toting saviour of Yorkshire's peatlands and the aristocratic gardener Vita Sackville-West, examining their idiosyncratic approaches to conservation. Jeremy Purseglove explains clearly and convincingly why it's not a good idea to extract as many resources as possible, whether it's the demand for palm oil currently denuding the forests of Borneo, cottonfield irrigation draining the Aral Sea, or monocrops spreading across Britain. The pioneer of engineering projects to preserve nature and landscape, first in Britain and then around the world, he offers fresh insights and solutions at each step.

Edward J. Goodwin
R1,367 Discovery Miles 13 670 Ships in 12 - 17 working days

Tropical coral reefs are important ecosystems. They are economically important to coastal communities living in predominantly developing countries, and also provide shoreline protection, catalyse land formation enabling human habitation, act as a carbon sink and are a repository for genetic and species diversity rivalling rainforests. In the face of mounting man-made pressure from pollution, climate change and over-exploitation, these ecosystems increasingly need action to be taken to ensure their conservation and long term sustainable development. International Environmental Law and the Conservation of Coral Reefs breaks new ground by providing the first in-depth account of the ways in which multilateral environmental treaty regimes are seeking to encourage and improve the conservation of tropical coral reef ecosystems. In so doing, the work aims to raise the profile of such activities in order to reinforce their status on the environmental agenda. The book also has wider implications for international environmental law, arguing that sectorial legal action, provided it remains co-ordinated through a global forum that recognises and reflects the inter-connections between all elements of the natural environment, is the most effective way for international law to enhance the conservation of certain habitats. This book will be invaluable to environmental lawyers, legal researchers, marine conservationists and other stakeholders in coral reefs.

SHORTLISTED FOR THE WAINWRIGHT PRIZE FOR WRITING ON GLOBAL CONSERVATION 'Pilcher is both very funny and very, very clever.' Gillian Burke 'Richly entertaining throughout.' Sunday Times For the last three billion years or so, life on Earth was shaped by natural forces. Evolution tended to happen slowly, with species crafted across millennia. Then, a few hundred thousand years ago, along came a bolshie, big-brained, bipedal primate we now call Homo sapiens, and with that, the Earth's natural history came to an abrupt end. We are now living through the post-natural phase, where humans have become the leading force shaping evolution. This thought-provoking book considers the many ways that we've altered the DNA of living things and changed the fate of life on earth. We have carved chihuahuas from wolves and fancy chickens from jungle fowl. We've added spider genes to goats and coral genes to tropical fish. It's possible to buy genetically-modified pets, eat genetically-modified fish and watch cloned ponies thunder up and down the polo field. Now, as our global dominance grows, our influence extends far beyond these species. As we warm our world and radically reshape the biosphere, we affect the evolution of all living things, near and far, from the emergence of novel hybrids such as the pizzly bear, to the entirely new strains of animals and plants that are evolving at breakneck speed to cope with their altered environment. In Life Changing, Helen introduces us to these post-natural creations and talks to the scientists who create, study and tend to them. At a time when the future of so many species is uncertain, we meet some of the conservationists seeking to steer evolution onto firmer footings with novel methods like the 'spermcopter', coral IVF and plans to release wild elephants into Denmark. Helen explores the changing relationship between humans and the natural world, and reveals how, with evidence-based thinking, humans can help life change for the better.

Ethical Debates in Orangutan Conservation (Hardcover): Alexandra Palmer Ethical Debates in Orangutan Conservation (Hardcover)
Alexandra Palmer
R3,922 Discovery Miles 39 220 Ships in 12 - 17 working days

Ethical Debates in Orangutan Conservation explores how conservationists decide whether, and how, to undertake rehabilitation and reintroduction (R&R) when rescuing orphaned orangutans. The author demonstrates that exploring ethical dilemmas is crucial for understanding ongoing disagreements about how to help endangered wildlife in an era of anthropogenic extinction. Although R&R might appear an uncontroversial activity, there is considerable debate about how, and why, it ought to be practised. Drawing on in-depth qualitative research with orangutan conservation practitioners, this book examines how ethical trade-offs shape debates about R&R. For example, what if the orphan fails to learn how to be an orangutan again, after years in the company of humans? What if she is sent into the forest only to slowly starve? Would she have been better off in a cage? Could the huge cost of sending a rescued ape back to the wild be better spent on stopping deforestation in the first place? Or do we have a moral obligation to rescue the orphan regardless of cost? This book demonstrates that deconstructing ethical positions is crucial for understanding ongoing disagreements about how to help our endangered great ape kin and other wildlife. Ethical Debates in Orangutan Conservation is essential reading for those interested in conservation and animal welfare, animal studies, primatology, geography, environmental philosophy, and anthropology.

This title was first published in 2000: The noble goals embodied in the Endangered Species Act are colliding with financial and social realities. Citizens increasingly face the costs of current policies, while initiatives which fail to respect liberty and property meet serious resistance at every turn. Despite widespread verbal support for saving species 'at any cost', when trade-offs become obvious, and values compete, support for these policies evaporates. This edited collection examines ethically and materially responsible approaches to this problem, written by leading international figures from a variety of disciplines. The result is the most comprehensive and constructive analysis of the effectiveness and viability of endangered species protection available.

Across the continental United States, one can identify 20 distinct forest cover types. Most of these are to be found on federal lands managed by the U.S. Forest Service and Bureau of Land Management. Those responsible for the management of trees that form the 20 different cover types and the diversity of forest wildlife that reside in them must have a solid grounding in concepts of forest management, especially silviculture, as well as concepts of wildlife management, in order to integrate both as part of any effective natural resource management plan. Forest Wildlife Ecology and Habitat Management provides both foresters and wildlife biologists responsible for managing forest resources with an integrated understanding of the relationship between forests and wildlife. Based on David Patton's 50 years of experience as a forester and wildlife biologist, the book shows readers how to look at forests as ecological systems and wildlife as part of the energy flow and nutrient cycling process within those systems. He offers readers a fundamental understanding of the natural processes that occur in a forest taking into consideration vegetation, water, and the natural effects of climate and time. He then provides a biological perspective on wildlife, discussing reproduction, behavior, feeding habits, and mobility. He also discusses the various influences on forests and wildlife by both natural and human-caused events. Covering those forest types included in the U.S. National Atlas, and associating over 1,100 wildlife species with 20 major forest types in 48 states, Professor Patton provides recommendations for ways to restore and maintain wildlife habitat by direct and indirect coordination. Towards this end, the author - Evaluates various approaches to integrate forestry and wildlife management Offers a number of practical management strategies, emphasizing a progressive holistic approach

Animal population ecology comprises the study of variations, regulation, and interactions of animal populations. This book discusses the fundamental notions and findings of animal populations on which most of the ecological studies are based. In particular, the author selects the logistic law of population growth, the nature of competition, sociality as an antithesis of competition, the mechanism underlying the regulation of populations, predator-prey interaction processes, and interactions among closely related species competing over essential resources. These are the notions that are considered to be well-established facts or principles and are regularly taught at ecology classes or introduced in standard textbooks. However, the author demonstrates that these notions are still inadequately understood, or even misunderstood, creating myths that would misguide ecologists in carrying out their studies. He delves deeply into those notions to reveal their real nature and draws a road map to the future development of ecology.

The renowned zoologist Fritz Eloff became interested in the Kalahari lion in 1958 when he first heard a lion roaring from the red dunes surrounding the camp. So impressive was the earth-trembling sound that he decided to devote his studies to these predators. This meant that he also had to become familiar with the Kalahari, its dust, its intense heat during the day and freezing cold nights, its vegetation, all the mammals and birds that form part of the lion’s food chain as well as the other predators the lion has to compete with. This book is the result of 40 years of extensive research and numerous exciting adventures. Written in an accessible style, it imparts information about the physical characteristics of the Kalahari lion, its habitat, role in the ecosystem and interaction with humans. The book concludes with the stories of a number of legendary male and female lions, and the author’s view on the survival of these magnificent animals in an ever changing environment.

In this saline odyssey, Clive Chatters has explored his favourite creeks, pools and mudflats to bring us an absorbing celebration of the ecology, biology, geology and history of this scarce and mysterious habitat. There are Tadpole Shrimps, and rare sedges, waders and Wild Celery - even inland saltmarshes - in this tour de force by a superb naturalist and writer." BRETT WESTWOOD, naturalist, author and radio presenter Saltmarshes are among Britain's most diverse and dynamic landscapes. They abound around our shores but may also be found inland and at altitude - wherever water, salt and vegetation combine. The species they support range from extreme rarities of specialised habitats to the less demanding denizens of coastal wetlands. Here is a landscape of international importance for migratory birds, endemic plants and an exceptional variety of invertebrates. Clive Chatters has a lifetime's affinity with saltmarshes. In this fifth volume of the British Wildlife Collection, he celebrates their natural history and diversity, from the highly distinctive marshes in the Scottish Highlands to the urban remnants of the Thames estuary now engulfed within the capital. By examining the past of these complex habitats, we can gain an insight into how they have developed, and an understanding of their relationship with people. In addition to their exceptionally diverse natural history, saltmarshes are sources of food and medicine, they play a pivotal role in flood defence and carbon sequestration, and have inspired artistic endeavour.

For nearly a quarter century, the polar bears of Churchill were routinely run down and shot by the military, by residents and by conservation officers who were brought in during the late 1960s to protect people. According to one scientist who was there at the time, polar bears were treated more like "great white rats" than the world's largest predator. But then something remarkable happened. During the 1970s the residents of Churchill decided that it was time to find a more peaceful way of living with polar bears.
In the years that followed, scientists conducted studies on the polar bear population and in relatively short order the bears of Churchill became the most studied group of large predators in the world.
