Aquaculture is a rapidly growing, successful approach to improving diets by providing more high quality fish and shellfish protein. It is also an industry with major unresolved issues because of its negative impact on the environment. This book is a pioneering effort in the development of environmentally benign aquaculture methods.

The species-area relationship (SAR) describes a range of related phenomena that are fundamental to the study of biogeography, macroecology and community ecology. While the subject of ongoing debate for a century, surprisingly, no previous book has focused specifically on the SAR. This volume addresses this shortfall by providing a synthesis of the development of SAR typologies and theory, as well as empirical research and application to biodiversity conservation problems. It also includes a compilation of recent advances in SAR research, comprising novel SAR-related theories and findings from the leading authors in the field. The chapters feature specific knowledge relating to terrestrial, marine and freshwater realms, ensuring a comprehensive volume relevant to a wide range of fields, with a mix of review and novel material and with clear recommendations for further research and application.

An eloquent introduction to the ethical and philosophical values at stake in biological conservation, this book familiarizes readers with the general issues and possible solutions to the problems societies face in simultaneously conserving nature and promoting culture.

'Shearwater is sheer delight, a luminous portrait of a magical seabird which spans the watery globe' Daily Mail. 'Charming and impassioned ... a rich tribute to an extraordinary bird.' Horatio Clare, author of A Single Swallow and Heavy Light. A very personal mix of memoir and natural history from the author of Liquid Gold. Ten weeks into its life, a Manx shearwater chick will emerge from its burrow and fly 8,000 miles from the west coast of the British Isles to the South Atlantic. It will be unlikely to touch land again for four years. Part memoir, part homage to wilderness, Shearwater traces the author's 50-year obsession with one of nature's supreme travellers. In the finest tradition of nature writing, Roger Morgan-Grenville, author of Liquid Gold - described by Mary Colwell (Curlew Moon) as 'a book that ignites joy and warmth' - unpicks the science behind its incredible journey; and into the story of a year in the shearwater's life, he threads the inspirational influence of his Hebridean grandmother who instilled in him a love of wild places and wild animals. Full of lightly-worn knowledge, acute human observation and self-deprecating humour, Shearwater brings to life a truly mysterious and charismatic bird.

This comprehensive volume describes how ecosystem services-based approaches can assist in addressing major global and regional water challenges, such as climate change, biodiversity loss, and water security in the developing world, by integrating scientific knowledge from different disciplines, such as hydrological modelling, environmental economics, psychology and international law. Empirical assessments at the national, catchment and regional levels are used to critically appraise this systemic approach, and the merits and potential limitations are presented. The practicalities of this approach with regard to water resources management, nature conservation, and sustainable business practices are discussed, and the role of society in underpinning the concept of ecosystem services is explored. Presenting new insights and perspectives on how to shape future strategies, this contributory volume is a valuable reference for researchers, academics, students and policy makers, in environmental studies, hydrology, water resource management, ecology, environmental law, policy and economics, and conservation biology.

Freshwater mussels are declining rapidly worldwide. Propagation has the potential to restore numbers of these remarkable organisms, preventing extinction of rare species and maintaining the many benefits that they bring to aquatic ecosystems. Written by practitioners with firsthand experience of propagation programs, this practical book is a thorough guide to the subject, taking readers through the process from start to finish. The latest propagation and culture techniques are explored as readers follow freshwater mussels through their amazing and complex life cycle. Topics covered include the basics of building a culture facility, collecting and maintaining brood stock, collecting host species, infesting host species with larval mussels, collecting and culturing juvenile mussels, releasing juveniles to the wild, and post-release monitoring. This will be valuable reading for any biologist interested in the conservation of freshwater mussel populations.

The worldwide development of ecotourism-including adventures such as mountain climbing and whitewater rafting, as well as more pedestrian pursuits such as birdwatching-has been extensively studied, but until now little attention has been paid to why vacationers choose to take part in what are often physically and emotionally strenuous endeavors. Drawing on ethnographic research and his own experiences working as an ecotour guide throughout the United States and Latin America, Robert Fletcher argues that participation in rigorous outdoor activities resonates with the particular cultural values of the white, upper-middle-class Westerners who are the majority of ecotourists. Navigating 13,000-foot mountain peaks or treacherous river rapids demands deferral of gratification, perseverance through suffering, and a willingness to assume risks in pursuit of continuous progress. In this way, characteristics originally cultivated for professional success have been transferred to the leisure realm at a moment when traditional avenues for achievement in the public sphere seem largely exhausted. At the same time, ecotourism provides a temporary escape from the ostensible ills of modern society by offering a transcendent "wilderness" experience that contrasts with the indoor, sedentary, mental labor characteristically performed by white-collar workers.

AMERICA'S MARINE SANCTUARIES tells the story of fourteen underwater places so important they are under special protection, together forming the US National Marine Sanctuary System. These sanctuaries, spanning more than 620,000 square miles and ranging from the Florida Keys to the Great Lakes and to the Hawaiian Islands, are critical and breath-taking marine habitats that provide homes to endangered and threatened species. They, also, preserve America's rich maritime heritage and act as living laboratories for science, research, education and conservation, offering outdoor recreation experiences for all ages. Through 150 full-colour photographs and lively narrative, AMERICA'S MARINE SANCTUARIES showcases each of the marine sanctuaries and the creatures that live there, from whales and manatees to Hawaiian monk seals and Laysan ducks, as well as sunken ships from the Ghost Fleet and USS Monitor to Shipwreck Alley. The book underscores how marine sanctuaries have shaped the nation's development, survival, and identity and celebrates these protected underwater treasures for all they can tell us about our communities, our country and our world.

It is being increasingly recognised that cultural and biological diversity are deeply linked and that conservation programmes should take into account the ethical, cultural and spiritual values of nature.

Conservationists have long been aware that political
boundaries rarely coincide with natural boundaries.
From the establishment of early "peace parks"to the
designation of continental migratory pathways, a
wide range of transborder mechanisms to protect
biodiversity have been established by conservationists
in both the public and private sectors.
Conservation Across Borders presents a broad
overview of the history of transboundary conservation
efforts and an accessible introduction to current issues surrounding
the subject. Through detailed examinations of two initiatives, the
International Sonoran Desert Alliance (ISDA) and the Yellowstone to
Yukon Initiative (Y2Y), the book helps readers understand the benefits
and challenges of landscape-scale protection.
In addition to discussing general concepts and the specific experience
of ISDA and Y2Y, the author considers the emerging concept of "conservation
effectiveness" and offers a comparative analysis of the two
projects. The book ends with a discussion of the complex relationships
among civil society, governments, and international borders.
By considering the history, goals, successes, and failures of two divergent
initiatives, the book offers important insights into the field of
transborder conservation along with valuable lessons for those studying
or working in the field.

Post-war Afghanistan is fragile, volatile, and perilous. It is also a place of extraordinary beauty. Evolutionary biologist Alex Deghan came to Afghanistan and created a startup, Conservation X Labs, to save Afghanistan's unique and extraordinary wildlife and natural landscape after decades of war. His workplace was so remote that roads themselves would disappear, and travel was by foot, yak, or mule, following ancient pathways for weeks into the mountain kingdoms and desolate landscapes. Conservation, it turned out, provided a common bond between Alex's team and the people of Afghanistan, where his international team worked unarmed in some of the most dangerous places in the country. They successfully built the country's first national park, completed the first wildlife survey in thirty years, and worked to stop the poaching of the country's iconic endangered animals, including the elusive snow leopard. In doing so, they restored a part of Afghan identity that is ineffably tied to the land itself. For a people who had spent decades as refugees or subject to the horrors and desolation of war, the quest to restore Afghanistan's wildlife became the restoration of Afghanistan's very culture and deep history.

The book covers the spread of conservation agriculture (CA) to regions including Brazil, Argentina, Canada, Australia, Europe and emerging CA destinations in Asia and Africa. Topics covered include the various components of CA, and how their individual and combined implementation influence productivity, soil health and environmental quality under diverse edaphic and climatic conditions. The book will be useful to teachers, researchers, extensionists, farmers, and students interested in environmental quality.

Until now, biological invasions have been conceptualised and studied mainly as a linear process: from introduction to establishment to spread. This volume charts a new course for the field, drawing on key developments in network ecology and complexity science. It defines an agenda for Invasion Science 2.0 by providing new framings and classification of research topics and by offering tentative solutions to vexing problems. In particular, it conceptualises a transformative ecosystem as an open adaptive network with critical transitions and turnover, with resident species heuristically learning and fine-tuning their niches and roles in a multiplayer eco-evolutionary game. It erects signposts pertaining to network interactions, structures, stability, dynamics, scaling, and invasibility. It is not a recipe book or a road map, but an atlas of possibilities: a 'hitchhiker's guide'.

A unified theory of conservation that addresses the broad problem of conservation, the principles that inform conservation choices, and the application of those principles to the management of the natural world. The conservation of natural resources, like that of any other asset, involves trade-offs. Yet, in a world faced with the harsh realities of climate change, crafting the right environmental policies is an increasingly urgent task. In Conservation, Charles Perrings and Ann Kinzig bring together new research in economics and biodiversity to investigate conservation decisions and the theory behind them. Perrings and Kinzig apply the concept of conservation broadly to examine how the principles of conservation apply to the management of the natural world. They demonstrate that the same basic principles serve as the foundation of all rational conservation decisions, from managing financial assets to safeguarding at-risk ecosystems. Whether someone is deciding to hold or dispose of a stock or whether to exploit or preserve a natural resource, they are better off choosing to conserve a resource when its value to them, if conserved, is greater than its value when converted. The book also considers the context of such conservation decisions. Just as national tax rules influence choices about financial investments, environmental regulations within countries, and environmental agreements between countries, impact the decisions regarding natural resources. Building on their basic theory of conservation, Perrings and Kinzig address key issues in the field of environmental economics, including the valuation of ecosystem services and environmental assets; the limits on the substitutability of produced and natural capital; and the challenges posed by the often weak markets for ecosystem services oriented toward the public good. They also address the problem of scale: while decisions might be easier to make at the local level, many conservation policies need to apply at either the national or international level to succeed. Written by experts from both social and hard sciences, this book presents a unified theory of conservation and provides a model for a more effective way to approach the vitally important issue.

The Coccinellidae are a family of beetles, known variously as ladybirds or ladybugs. In Britain alone, some 46 species belong to the Coccinellidae family, although only 26 of these are recognisably ladybirds. Composed largely of Professor Michael Majerus' lifetime work, and updated by two leading experts in the field, this book reveals intriguing insights into ladybird biology from a global perspective. The popularity of this insect group has been captured through societal and cultural considerations, coupled with detailed descriptions of complex scientific processes, to provide a comprehensive and accessible overview of these charismatic insects. Bringing together many studies on ladybirds, this book has been organised into themes, ranging from anatomy and physiology to ecology and evolution. This book is suitable for interested amateur enthusiasts, and researchers involved with ladybirds, entomology and biological control.

A valuable and unique contribution both to environmental ethics and public policy analysis of the preservation of species question.

Originally published in 1988. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Fish are one of the most important global food sources, supplying a significant share of the world's protein consumption. From stocks of wild Alaskan salmon and North Sea cod to entire fish communities with myriad species, fisheries require careful management to ensure that stocks remain productive, and mathematical models are essential tools for doing so. Fish Ecology, Evolution, and Exploitation is an authoritative introduction to the modern size- and trait-based approach to fish populations and communities. Ken Andersen covers the theoretical foundations, mathematical formulations, and real-world applications of this powerful new modeling method, which is grounded in the latest ecological theory and population biology. He begins with fundamental assumptions on the level of individuals and goes on to cover population demography and fisheries impact assessments. He shows how size- and trait-based models shed new light on familiar fisheries concepts such as maximum sustainable yield and fisheries selectivity-insights that classic age-based theory can't provide-and develops novel evolutionary impacts of fishing. Andersen extends the theory to entire fish communities and uses it to support the ecosystem approach to fisheries management, and forges critical links between trait-based methods and evolutionary ecology. Accessible to ecologists with a basic quantitative background, this incisive book unifies the thinking in ecology and fisheries science and is an indispensable reference for anyone seeking to apply size- and trait-based models to fish demography, fisheries impact assessments, and fish evolutionary ecology.

Tony Fitzjohn, part missionary, part madman, has been called "one of the world's most endangered creatures." An internationally renowned field expert on African wildlife, he is best known for the eighteen years he spent helping "Born Free"'s George Adamson return more than forty leopards and lions--including the celebrated Christian--to the wild in central Kenya.
"Born Wild" is the memoir of Fitzjohn's extraordinary life. It shows how a man driven by an impossibly restless spirit can do almost anything, from being a bouncer in a brothel, to surviving a vicious lion attack, to fighting with the Tanzanian government, to being appointed an Officer of the Order of the British Empire by the Queen.
A notorious hell-raiser given to scrapes with bandits, evil policemen, and wicked politicians, who has been shot at by poachers and chewed up by lions, Fitzjohn is also a wonderful raconteur. Shenanigans aside, he belongs to that rare species of humans who have sought refuge and meaning in a life truly dedicated to the restoration of the animal kingdom. Many times Tony Fitzjohn has put his life on the line for the cause in which he believes. "Born Wild" is the story of that passion.

'A must read for all wildlife lovers' Dominic Dyer Foxes, buzzards, crows, badgers, weasels, seals, kites - Britain and Ireland's predators are impressive and diverse and they capture our collective imagination. But many consider them to our competition, even our enemies. The problem is that predators eat what we farm or use for sport. From foxes and ravens attacking new-born lambs to weasels eating game-bird chicks, predators compete with us, putting them directly into the firing line. Farming, fishing, sport and leisure industries want to see numbers of predators reduced, and conservation organisations also worry that predators are threatening some endangered species. Other people, though, will go to great lengths to protect them from any harm. This clashing of worlds can be intense. So, what do we do? One of the greatest challenges facing conservation today is how, when and where to control predators. It is a highly charged debate. Mary Colwell travels across the UK and Ireland to encounter the predators face to face. She watches their lives in the wild and discovers how they fit into the landscape. She talks to the scientists studying them and the wildlife lovers who want to protect them. She also meets the people who want to control them to protect their livelihoods or sporting interests. In this even-handed exploration of the issues, Mary provides a thoughtful and reasoned analysis of the debates surrounding our bittersweet relationship with predators.
