'One of the most influential books about the natural world ever published' Paul Kingsnorth, Guardian 'There are some who can live without wild things, and some who cannot,' begins Aldo Leopold's totemic work of ecological thought. Ranging from lyrical observations of the changing seasons over a year on his Wisconsin farm to his hugely influential idea of a 'land ethic' signifying moral equilibrium between humans and all other life on earth, A Sand County Almanac changed perceptions of the natural world and helped give birth to the modern conservation movement. 'An unequivocal statement of conscience that will carry down the generations ... his argument seems more urgently true now than ever' The New York Times

Hunting the Hunters - At War with the Whalers (Paperback, New): Laurens de Groot Hunting the Hunters - At War with the Whalers (Paperback, New)
Laurens de Groot 1
R285 Discovery Miles 2 850 Ships in 4 - 6 working days

'As the rest of the world stood by and watched, Laurens risked everything to defend these extraordinary mammals from extinction. A truly powerful and inspiring story.' Susan Sarandon Laurens de Groot was a detective for the Dutch police, specializing in organized crime and environmental pollution. He was rapidly promoted through the ranks, but became increasingly disillusioned with failed prosecutions and minimal prison sentences. But although as a detective there was little he could do to stop the truly big criminals, there was a more radical option - direct action, not necessarily within the law. Laurens leaves his job, sells up, travels to Australia and joins Sea Shepherd, an international organization protecting marine wildlife. He soon finds himself in the middle of the war against the Japanese whaling fleet operating in the Antarctic whale sanctuary. As the Japanese hunt whales, Laurens and the Sea Shepherd crews hunt them. Their boats are tiny for the wild Southern Ocean, and as well as dealing with the extreme weather they are repeatedly attacked by the Japanese crews and nearly shipwrecked by ice. On one mission, their boat is rammed, cut in two and sunk by a whaling ship. This is war, with no quarter given. Hunting the Hunters is an action-packed and timely account of one man's extraordinary life, as well as an ongoing battle against a powerful nation determined to get its way no matter the cost. It's an important subject, one that a lot of people care about, and as Laurens tells the story in his own words this is a compelling and insightful book.

Besides the erroneous assumption that tropical fisheries are 'open access', the cases demonstrate that pre-existing systems (1) are concerned with the community of fishers and ensuring community harmony and continuity; (2) involve flexible, multiple and overlapping rights adapted to changing needs and circumstances; (3) that fisheries are just one component of a community resource assemblage and depend on both the good management of linked upstream ecosystems and risk management to ensure balanced nutritional resources of the community; and (4) pre-existing systems are greatly affected by a constellation of interacting external pressures.

Tropical Islands Biodiversity Crisis: - The Indo-West Pacific (Paperback, 2011 ed.): David J. W. Lane Tropical Islands Biodiversity Crisis: - The Indo-West Pacific (Paperback, 2011 ed.)
David J. W. Lane
R4,012 Discovery Miles 40 120 Ships in 18 - 22 working days

This work assesses the issues facing biodiversity maintenance on tropical islands, and the impacts of biodiversity loss. The emphasis is on the Indo-West Pacific region, which includes many small islands where the biodiversity is under threat as a result of not only climate change and habitat destruction, but invasions by organisms previously absent from an island. The contributors are distinguished biodiversity scientists from inside and outside the region, and cover topics ranging from the state of conservation action in South-East Asia, the role of parks, and the status and threat to endemics, to impacts of oil and gas exploration and forest fragmentation. Issues needing still to be addressed, especially in relation to implications of biodiversity loss or change for the maintenance of ecosystem processes, are highlighted. The conclusions and case studies have lessons for all involved in the conservation of the biotas and ecosystems of islands. Previously published in Biodiversity and Conservation 19:2 2010

Hypotheses are tested using data capable of generating useful results. The main conclusions include a retrospective of how key concepts defined and represented the various perspectives, skills and backgrounds that made up the multidisciplinary CEVIS project.

Fynbos - Ecology, Evolution, and Conservation of a Megadiverse Region (Paperback): Nicky Allsopp, Jonathan F. Colville, G.... Fynbos - Ecology, Evolution, and Conservation of a Megadiverse Region (Paperback)
Nicky Allsopp, Jonathan F. Colville, G. Anthony Verboom 1
R1,974 Discovery Miles 19 740 Ships in 10 - 15 working days

South Africa's fynbos region has intrigued biologists for centuries. It has achieved iconic status as a locus of megadiversity and therefore a place to study the ecological underpinnings of massive evolutionary radiations. Researchers have made great advances over the past two decades in unravelling the complexities of fynbos ecology and evolution, and the region has contributed significant insights into the adaptive radiations of large lineages, conservation science, pollination biology, invasive plant biology, and palaeoanthropology. Lessons from the fynbos offer much of value for understanding the origin, maintenance, and conservation of diversity anywhere in the world. This book provides the first synthesis of the field for 20 years, bringing together the latest ecological and evolutionary research on the South African global biodiversity hotspots of the Greater Cape Floristic Region - the iconic fynbos and succulent karoo. It explores the historical and modern physical and biological environment of this region, the circumstances and processes which have fostered its remarkable biodiversity, and the role this diversity has played in the emergence of modern humans. It also discusses the challenges of contemporary management and conservation of the region's biodiversity in the face of accelerating global change.

Handbook of Mammals of Madagascar (Hardcover): Nick Garbutt Handbook of Mammals of Madagascar (Hardcover)
Nick Garbutt
R1,148 Discovery Miles 11 480 Ships in 10 - 15 working days

Madagascar is home to one of the most remarkable assemblages of mammals on earth. Millions of years of isolation has resulted in the evolution of a suite of species that are exceptional for two major reasons. Firstly, every native non-volant species (approximately 210 species) is endemic. No other island or place on earth boasts such a combination of species richness and endemism. And secondly, these mammals have evolved an extraordinary diversity of body forms and lifestyles often displaying significant convergence with forms elsewhere but also at times evolving utterly unique features. Handbook of the Mammals of Madagascar describes all 217 native species, including bats, tenres, mice and lemurs, and a small number of introduced, non-native species. Species accounts are subdivided into sections covering description and identification, habitat and distribution (including distribution maps), behaviour and where to see. Over the past 15 years, major advances in research have been made into the island's mammal fauna and species accounts include all the latest information. Supporting chapters cover the island's regions and habitats, threats to mammals, conservation and important mammal watching sites. There is also a section covering the bizarre extinct mammal fauna. Throughout, the book is illustrated with exceptional, high-quality photography, often featuring species rarely photographed previously.

Wetland Techniques - Volume 2: Organisms (Paperback, 2013 ed.): James T. Anderson, Craig A. Davis Wetland Techniques - Volume 2: Organisms (Paperback, 2013 ed.)
James T. Anderson, Craig A. Davis
R3,628 Discovery Miles 36 280 Ships in 18 - 22 working days

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."

Birds and Habitat - Relationships in Changing Landscapes (Paperback, New): Robert J. Fuller Birds and Habitat - Relationships in Changing Landscapes (Paperback, New)
Robert J. Fuller
R1,722 Discovery Miles 17 220 Ships in 10 - 15 working days

The successful conservation of bird species relies upon our understanding of their habitat use and requirements. In the coming decades the importance of such knowledge will only grow as climate change, the development of new energy sources and the needs of a growing human population intensify the, already significant, pressure on the habitats that birds depend on. Drawing on valuable recent advances in our understanding of bird-habitat relationships, this book provides the first major review of avian habitat selection in over twenty years. It offers a synthesis of concepts, patterns and issues that will interest students, researchers and conservation practitioners. Spatial scales ranging from landscape to habitat patch are covered, and examples of responses to habitat change are examined. European landscapes are the main focus, but the book has far wider significance to similar habitats worldwide, with examples and relevant material also drawn from North America and Australia.

Bioremediation of Petroleum Hydrocarbons in Cold Regions (Paperback): Dennis M Filler, Ian Snape, David L Barnes Bioremediation of Petroleum Hydrocarbons in Cold Regions (Paperback)
Dennis M Filler, Ian Snape, David L Barnes
R1,385 Discovery Miles 13 850 Ships in 10 - 15 working days

This guide to bioremediation in cold regions is designed to aid environmental practitioners, industry, and regulators in the remediation of petroleum spills and contaminated sites in cold regions. Remediation design and technology used in temperate climates does not necessarily work in cold climates, and cleanup takes longer due to shorter treatment seasons, sub-freezing temperatures, ground freezing and thawing, and limited bioactivity. Environmental engineers and scientists from eight countries working in the polar regions combine their experiences and expertise with petroleum contamination to write this book. It contains in-depth discussions on regulations, freezing and frozen ground, identification and adaptations of cold-tolerant bacteria, contaminant transport in cold soils and permafrost, temperature effects on biodegradation, analytical methods, treatability studies, and nutritional requirements for bioremediation. Emphasis is given to practical and effective bioremediation methods for application in cold regions. Emerging technologies are also discussed.

Widespread in North American forest regions including the Rocky Mountains, the Boreal Owl (Aegolius funereus) was once the most numerous predatory bird in Eurasian boreal forests. Synthesising the results of unique long-term studies of Boreal Owls, this book explores hunting modes, habitats and foods, prey interactions, mating and parental care, reproduction, dispersal, survival and mortality, population regulation and conservation in boreal forests. Providing a detailed introduction to the species, the authors study the complex interactions of Boreal Owls with their prey species. They examine the inter-sexual tug-of-war over parental care, and the behavioural and demographic adaptations to environmental conditions that predictably and markedly fluctuate both seasonally and multi-annually. They also question whether Boreal Owls are able to time their reproductive effort to maximise lifetime reproductive success. Discussing the effect of modern forestry practices on owl populations, the book also examines how Boreal Owls could be managed to sustain viable populations.

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.

Terry Maple, Bonnie M Perdue
R5,256 Discovery Miles 52 560 Ships in 18 - 22 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.

Jerald S. Ault
R2,063 Discovery Miles 20 630 Ships in 10 - 15 working days

The core of a multibillion dollar sport fishing industry, tarpon and bonefish, two of the earth's oldest creatures, are experiencing obvious and precipitous population decline. Experienced anglers in the Florida Keys suggest a drop of approximately 90-95 percent for the bonefish population over the last 65 years. Despite the economic value of the industry and scientific value of these ancient fish, very little information is available about their movements and migrations, population dynamics, life histories, and reproductive habits. With contributions from some of the world's leading experts, Biology and Management of the World Tarpon and Bonefish Fisheries synthesizes existing scientific literature, presents new perspectives, and introduces original scientific research to guide fishery management and conservation efforts for building sustainable fisheries. Divided into five sections, the book begins with an overview of the state of the world's fisheries for tarpon and bonefish. The second section reviews the biology and life history dynamics of these fish with contributions on conservation genetics, reproductive biology and early life development, as well as resolving gaps in evolutionary lineage and taxonomy. Covering population dynamics and resource ecology, the third section discusses migratory patterns and the use of tagging. Highlighting the lore and appeal of these fascinating sport fish, the book concludes by introducing a myriad of proposals designed to improve fishery sustainability by conducting census, enforcing catch-and-release programs, and supporting science-based management decision making. Promoting a better understanding of the biological and fishery management issues that are paramount to the sustainable future of these valuable fishery resources, Biology and Management of the World Tarpon and Bonefish Fisheries provides a foundation for discussion and broad communication about the past present and future of these magnificent fish.

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.

R1,582 Discovery Miles 15 820 Ships in 18 - 22 working days

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.
