Spix's Macaw - The Race to Save the World's Rarest Bird (Paperback, New Ed): Tony Juniper Spix's Macaw - The Race to Save the World's Rarest Bird (Paperback, New Ed)
Tony Juniper
R286 Discovery Miles 2 860 Ships in 10 - 17 working days

"Not only were we in the presence of the last Spix's Macaw at Curaca – it was the last wild Spix's Macaw anywhere…Unlike all other mortal creatures that must one day face the inevitable reality of their own demise, the death of this bird would mark the end not only of himself but his entire kind."

In December 1897 the Honourable and Reverend F.G. Dutton lamented that 'there are so many calls on a parson's purse, that he cannot always treat himself to expensive parrots'. He was hoping to purchase a Spix's Macaw, a rare and beautiful parrot found in a remote area of Brazil. Today, the parson's search for a Spix would be in vain. By the turn of the millenium, only one survivor existed in the wild.

'Spix's Macaw' tells the heartbreaking story of a unique band of brilliant blue birds – who talk, fall in love, and grieve – struggling against the forces of extinction. Discovered in the early nineteenth century, the Spix soon became the most expensive bird in the world. By the end of the twentieth century the birds became gram-for-gram more valuable than heroin; so treasured that they drew up to $40,000 on the black market. When, in 1990, only one was found to be living in the wild, an amnesty was declared allowing private collectors to come forward with their illegal birds. The last Spix would be paired with a captive bird, in the hope that the secrets of survival in the wild would be passed down to future generations.

In a breathtaking display of stoicism and endurance, the loneliest bird in the world had lived without a mate for fourteen years, had outwitted predators and second-guessed the poachers. But would he take to a new companion? Spix's Macaws are like humans – they can't be forced to love. With exquisite detail, this book tells the dramatic story of the international rescue operation, and of the humans whose selfishness and greed brought a beautiful species to the brink of extinction. The long, lonely flight of the last Spix's Macaw is both a love story and an environmental parable for our times.

A remarkable look at the rarest butterflies, how global changes threaten their existence, and how we can bring them back from near-extinction Most of us have heard of such popular butterflies as the Monarch or Painted Lady. But what about the Fender’s Blue? Or the St. Francis’ Satyr? Because of their extreme rarity, these butterflies are not well-known, yet they are remarkable species with important lessons to teach us. The Last Butterflies spotlights the rarest of these creatures—some numbering no more than what can be held in one hand. Drawing from his own first-hand experiences, Nick Haddad explores the challenges of tracking these vanishing butterflies, why they are disappearing, and why they are worth saving. He also provides startling insights into the effects of human activity and environmental change on the planet’s biodiversity. Weaving a vivid and personal narrative with ideas from ecology and conservation, Haddad illustrates the race against time to reverse the decline of six butterfly species. Many scientists mistakenly assume we fully understand butterflies’ natural histories. Yet, as with the Large Blue in England, we too often know too little and the conservation consequences are dire. Haddad argues that a hands-off approach is not effective and that in many instances, like for the Fender’s Blue and Bay Checkerspot, active and aggressive management is necessary. With deliberate conservation, rare butterflies can coexist with people, inhabit urban fringes, and, in the case of the St. Francis’ Satyr, even reside on bomb ranges and military land. Haddad shows that through the efforts to protect and restore butterflies, we might learn how to successfully confront conservation issues for all animals and plants. A moving account of extinction, recovery, and hope, The Last Butterflies demonstrates the great value of these beautiful insects to science, conservation, and people.

'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.

Around the World in 80 Species - Exploring the Business of Extinction (Hardcover): Jill Atkins, Barry Atkins Around the World in 80 Species - Exploring the Business of Extinction (Hardcover)
Jill Atkins, Barry Atkins
R2,832 Discovery Miles 28 320 Ships in 10 - 15 working days

The world is currently experiencing a sixth period of mass species extinction, and extinction of flora and fauna is caused by a variety of factors arising from industrial activity and increasing human population, such as global warming, climate change, habitat loss, pollution and use of pesticides. Most causes of extinction are linked to corporate activity, either directly or indirectly. Around the World in 80 Species: Exploring the Business of Extinction responds to the ongoing mass extinction crisis engulfing our planet by exploring the ways in which accounting, business and finance can be used to prevent species extinctions. From Africa to the Far East and from Europe to the Americas, the authors explore species loss and how businesses can stop mass extinctions through greater transparency, and through closer engagement with their investors and wildlife organisations. The book concludes that global capitalism has led us to this extinction crisis and that therefore the mechanisms of capitalism - namely accounting, finance, investment - can help to pull us out. Businesses must urgently address extinction before it is too late for all species, including ourselves. As the first book to explore corporate accounting and accountability in relation to species on the brink of extinction, this book will be of great interest to both professionals and a wider audience interested in the causes and prevention of extinction.

Conservation and Sustainable Use - A Handbook of Techniques (Paperback): E.J.Milner- Gulland, J. Marcus Rowcliffe Conservation and Sustainable Use - A Handbook of Techniques (Paperback)

R2,167 Discovery Miles 21 670 Ships in 10 - 15 working days

The relentless exploitation and unsustainable use of wildlife, whether for food, medicine or other uses, is a key concern for conservationists worldwide. Indeed, wildlife conservation and sustainable use have recently become centrepieces in conservation and development research. Assessment, interpretation and ultimate action in a scientific study of exploited species must consider numerous factors: from the biology, habitat requirements and population dynamics of the species in question to the relationships that people have with their environment and the species within it. Any long-term management plan must ensure that people and wildlife can coexist - otherwise it is doomed to failure.
Conservation and Sustainable Use provides a practical and integrated approach to carrying out research on the conservation of exploited species. It is relevant to both tropical and temperate biomes and is applicable to all exploited species, including mammals, fish and plants. It describes both the practical (field) and theoretical (modelling) techniques for obtaining and interpreting information, integrating biological, social, economic and institutional analyses. It also demonstrates how to translate information into effective action through appropriate interventions, from legislation to changing people's attitudes. This is the first time that all these issues have been covered together in a single, practically-orientated volume.
This book will be essential reading for graduate level students and researchers in conservation biology, human ecology, sociology and resource economics. It will also provide an important reference for anyone who is interested in carrying out a scientifically-basedconservation programme for an exploited species, including field biologists, wildlife managers and practitioners in the fields of conservation and international development.

‘In Clive, we have an ever-fascinating guide to Britain’s heathery districts, not only marvelling at the wildlife of such wild places, but also celebrating their diverse origins, uses and cultural resonances’ - ANDREW BYFIELD Heathlands are so much more than simply purple carpets of heather. They are ancient landscapes found throughout Britain that support a complex of inter-related species and an immense diversity of habitats. They also possess a unique human history defined by the struggle between pastoralism and the competing demands of those who seek exclusive use of the land. In this latest addition to the British Wildlife Collection, Clive Chatters introduces us to Britain’s heathlands and their anatomy. He then takes the reader on a geographical heathland tour – from the maritime sub-arctic of the Shetlands to the mild wetness of the Atlantic coast – with an in memoriam nod to those heaths that have been erased from common memory and understanding. He concludes with a review of how people have perceived and used heathland wildlife over the ages, and sets out a future vision for this iconic landscape, its unique habitats and the species that live there. Most of our heaths are pale shadows of their former selves. However, Chatters argues, it is not inevitable that the catastrophic losses of the recent past are the destiny of our remaining heaths. Should we wish, their place in the countryside as an integral part of British culture can be secured.

Habitat Conservation - Managing the Physical Environment (Paperback): A. Warren Habitat Conservation - Managing the Physical Environment (Paperback)
A. Warren
R3,158 Discovery Miles 31 580 Ships in 10 - 15 working days

Habitat Conservation examines the relationship between habitat and ecosystem dynamics. Over the last decade scientists have made advances in their understanding of this relationship and this has had major impacts on their approach to nature conservation management.
In many habitats conservation management needs to take into account the physical dynamic processes such as the impact of air, soil and water as well as the biological processes.
Covering habitats ranging from mountains to floodplains to coastal dunes and rivers this text discusses:

  • how the biological and physical processes interact in each habitat
  • explores the current and future impact of global warming and sea-level rise and;
  • uses case studies to demonstrate how different habitats can be naturally managed and restored.
Written by geomorphologists, hydrologists, climatologists and limnologists this is a fundamental text for masters and undergraduate students studying nature conservation, habitat ecology and environmental management. It will also be essential reading for all conservationists, environmental consultants, managers and engineers.

Alan Hildrew, Paul Giller
R1,318 Discovery Miles 13 180 Ships in 9 - 17 working days

The challenges that the world's running water systems now face have never been more numerous or acute; at the same time, these complex habitats remain absolutely crucial to human wellbeing and future survival. If rivers can ever be anything like sustainable, ecology needs to take its place as an equal among the physical sciences such as hydrology and geomorphology. A real understanding of the natural history and ecology of running waters must now be brought even more prominently into river management. The primary purpose of this textbook is to provide the up-to-date overview that students and practitioners will require to achieve this aim. The book's unifying focus is on rivers and streams as ecosystems in which the particular identity of organisms is not the main emphasis but rather the processes in which they are involved - specifically energy flow and the cycling of materials. It builds on the physicochemical foundations of the habitat templet and explores the diversity and adaptations of the biota, progressing from the population and community ecology of organisms and linking them to ecosystem processes and services in the wider biosphere via the complexities of species interactions and food webs. These include water quality and patterns of river discharge, as well as aesthetics, waste disposal, and environmental health. While the book is not primarily focused on application per se, each chapter addresses how humans affect rivers and, in turn, are affected by them. A final, future-oriented chapter identifies key strategic areas and sets a roadmap for integrating knowledge of natural history and ecology into policy and management. The Biology and Ecology of Streams and Rivers is an accessible text suitable for both senior undergraduate and graduate students taking courses in both lotic and general ecology as well as more established researchers, practitioners, managers, and conservationists requiring a concise and contemporary overview of running waters.

R2,532 Discovery Miles 25 320 Ships in 10 - 15 working days

The only hope for successful conservation of America's threatened, endangered, and at-risk wildlife is through voluntary, cooperative partnerships that focus on private land, where over 75% of at-risk species can be found. Private landowners form the bedrock of these partnerships, and they have a long history of rising to meet the challenge of conservation. But they can't do it alone. This book is a guide for private landowners who want to conserve wildlife. Whether engaged in farming, ranching, forestry, mining, energy development, or another business, private working lands all have value as wildlife habitat, with the proper management and financial support. This book provides landowners and their partners with a roadmap to achieve conservation compatible with their financial and personal goals. This book introduces the art and language of land management planning as well as regulatory compliance with laws such as the Endangered Species Act of 1973. It categorizes and explains the tools used by wildlife professionals to implement conservation on private lands. Moreover it documents the multitude of federal, state, local, and private opportunities for landowners to find financial and technical assistance in managing wildlife, from working with a local NGO to accessing the $6 billion per year available through the federal Farm Bill.

This book explores the factors affecting the survival of small populations. As the human impact on Earth expands, populations of many wild species are being squeezed into smaller and smaller habitats. As a consequence, they face an increasing threat of extinction. National and international conservation groups rush to add these populations, species and sub-species to their existing endangered and threatened lists. In nations with strong conservation laws, listing often triggers elaborate plans to rescue declining populations and restore their habitats. The authors review these theoretical ideas, the existing data, and explore the question: how well do small and isolated populations actually perform? Their case study group is the song sparrows of Mandarte Island, British Columbia. This population is small enough and isolated enough so that all individuals can be uniquely marked and their survival and reproduction monitored over many generations. This is one of the strongest long-term ecological studies of a contained vertebrate population, now in its 31st year.

R4,261 Discovery Miles 42 610 Ships in 10 - 17 working days

Nutrition spans a wide range of mechanisms from acquisition of food to digestion, absorption and retention of energy substrates, water and other nutrients. Nutritional principles have been applied to improving individual health, athletic performance and longevity of humans and of their companion animals, and to maximizing agricultural efficiency by manipulating reproduction or growth of tissues such as muscle, hair or milk in livestock. Comparative nutrition borrows from these tra- tional approaches by applying similar techniques to studies of ecology and physiology of wildlife. Comparative approaches to nutrition integrate several levels of organization because the acquisition and flow of energy and nutrients connect individuals to populations, populations to communities, and communities to ecosystems. Integrative Wildlife Nutrition connects behavioral, morphological and biochemical traits of animals to the life history of species and thus the dynamics of populations. An integrated approach to nutrition provides a practical framework for understanding the interactions between food resources and wildlife popu- tions and for managing the harvest of abundant species and the conservation of threatened populations. This book is for students and professionals in animal physiology and ecology, conservation biology and wildlife management. It is based on our lectures, dem- strations and practical classes taught in the USA, Canada and Australia over the last three decades. Instructors can use Integrative Wildlife Nutrition as a text in wildlife and conservation biology programs, and as a reference source for related courses in wildlife ecology.

"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.

The passenger pigeon, the great auk, the Tasmanian tiger-the memory of these vanished species haunts the fight against extinction. Seeking to save other creatures from their fate in an age of accelerating biodiversity loss, wildlife advocates have become captivated by a narrative of heroic conservation efforts. A range of technological and policy strategies, from the traditional, such as regulations and refuges, to the novel-the scientific wizardry of genetic engineering and synthetic biology-seemingly promise solutions to the extinction crisis. In The Fall of the Wild, Ben A. Minteer calls for reflection on the ethical dilemmas of species loss and recovery in an increasingly human-driven world. He asks an unsettling but necessary question: Might our well-meaning efforts to save and restore wildlife pose a threat to the ideal of preserving a world that isn't completely under the human thumb? Minteer probes the tension between our impulse to do whatever it takes and the risk of pursuing strategies that undermine our broader commitment to the preservation of wildness. From collecting wildlife specimens for museums and the wilderness aspirations of zoos to visions of "assisted colonization" of new habitats and high-tech attempts to revive long-extinct species, he explores the scientific and ethical concerns vexing conservation today. The Fall of the Wild is a nuanced treatment of the deeper moral issues underpinning the quest to save species on the brink of extinction and an accessible intervention in debates over the principles and practice of nature conservation.

R8,041 Discovery Miles 80 410 Ships in 10 - 15 working days

Despite many wetland sites having suffered various forms of damage, there has been a recent recognition that, in some instances, it may be possible to rectify this through deliberate and controlled restoration programmes. Wetland restoration involves a variety of disciplines and interests, concerning groups who are interested in wetland utilization (such as farmers, foresters, peat extractors and water authorities), as well as those who wish to safeguard the site or its wildlife (such as conservationists, natural historians, ecologists and archaeologists). Interaction between these action groups is regulated by planners and politicians, and disagreements are frequently fuelled by an absence of reliable information. In these circumstances, wetland scientists have a responsibility to try to acquire and interpret relevant data in an informed, objective and impartial way. This volume reviews the current scientific knowledge of wetland restoration, identifying the problems and opportunities associated with it. Based on revised and edited contributions to the recent Restoration of Temperate Wetlands symposium, it provides a broad overview of current information and experience of wetland restoration. In some cases it highlights the lack of knowledge available and illustrates how difficult it can be to make informed decisions. With contributions from Scandinavia, Europe, Australia, the USA and Canada, outlining the latest research and observations from a range of international wetland scientists and practitioners, this book provides a critical review of current information and knowledge and gives insights into many aspects of wetland restoration, with a focused approach to the ecological principles that underpin it.

R1,463 Discovery Miles 14 630 Ships in 9 - 17 working days

Shortlisted for the 2018 TWS Wildlife Publication Awards in the authored book category In recent years, conflicts between ecological conservation and economic growth forced a reassessment of the motivations and goals of wildlife and forestry management. Focus shifted from game and commodity management to biodiversity conservation and ecological forestry. Previously separate fields such as forestry, biology, botany, and zoology merged into a common framework known as conservation biology and resource professionals began to approach natural resource problems in an interdisciplinary light. Wildlife Habitat Management: Concepts and Applications in Forestry presents an integrated reference combining silvicultural and forest planning principles with principles of habitat ecology and conservation biology. With extensive references and case studies drawn from real situations, this book begins with general concepts such as habitat selection, forest composition, influences on habitat patterns, and the dynamics of disturbance ecology. It considers management approaches for specific habitats including even-aged and uneven-aged systems, riparian areas, and dead wood and highlights those approaches that will conserve and manage biodiversity. The author discusses assessment and prioritization policies, monitoring techniques, and ethical and legal issues that can have worldwide impact. Detailed appendices provide a glossary, scientific names, and tools for measuring and interpreting habitat elements. Writing in a species-specific manner, the author emphasizes the need to consider the potential effects of management decisions on biodiversity conservation and maintains a holistic approach throughout the book. Drawing from the author's more than 30 years working and teaching in natural resources conservation, Wildlife Habitat Management: Concepts and Applications in Forestry provides a synopsis of current preservation techniques and establishes a common body of knowledge from which to approach the conservation of biodiversity in the future.

Conserving Living Natural Resources is an introductory textbook for students of conservation biology and resource management. It presents the historical and conceptual contexts of three seminal approaches to the management of living natural resources: utilitarian management for harvest of featured species and control of unwanted species, protection and restoration of populations and habitats to maintain biodiversity, and management of complex ecosystems to sustain both productivity and biodiversity. Rather than endorsing a single approach as the only correct one, this book investigates the historical and philosophical contexts, conceptual frameworks, principal techniques, and the limitations of each approach.

Organotin compounds, used as antifouling biocides since 1960, are chemical compounds that act as endocrine disrupters. It is not known how organotin compounds cause hormone disturbance, however, and many questions remain about their effect on aquatic organisms. Studies on organotin compounds have recently evolved, with many new findings reported. Following a worldwide ban on organotin compounds in 2008, alternative compounds will mainly be used, with the potential for coastal areas to become contaminated, causing, among other effects, cholinesterase inhibition in aquatic organisms. Use of alternative compounds must be controlled to avoid such errors. These and other findings are described and concisely summarized in this book, providing a useful reference in countries where alternative biocides are being considered. Included are studies on the effects on marine organisms, making this book an excellent aid to experts in environmental chemistry, to government organizations, and to students.

From an upbringing in the Lake District, the author developed a deep interest in natural history which became an all-consuming passion. As a 'licensed rehabilitation keeper', he cared for a wide range of injured and orphaned wildlife, giving individuals a second chance by returning them to the wild. He reveals how and why he later graduated to barn owl conservation. The author describes his many encounters with barn owls, from the acquisition of his first breeding pair; 'Barney', a completely humanised owl; to stories of the fascinating array of people involved in releasing, studying, and simply marvelling at this beautiful bird. Although there is a funny side to most situations, there are also the inevitable disasters and disappointments of conservation work, such as the accidental or deliberate sabotaging of releases or the killing of released birds. The reader shares in the author's disappointment and frustration at the sheer cost in time and money and his frequent self-doubt about the success of the whole exercise. However, there are descriptions of more enjoyable activities such as bird ringing, watching home-grown birds metamorphose from ugly pink scraps into creatures of ethereal beauty, and the seemingly limitless energy and enthusiasm of countless landowners and volunteers who are totally committed to the reintroduction of the barn owl. After almost 20 years, there is now evidence of a marked increase in barn owl numbers in areas where the author has worked. During this period, he bred and released around 250 birds, put up nest boxes and advised on barn owl-friendly approaches to land management. These activities helped to reverse the decline in population as areas were repopulated and also created reservoirs of wild breeding barn owls, whose offspring colonised other under-populated parts of the country. The return of the barn owl not only heralds a brighter future for the British countryside, but also shows, at a time of great public concern about the state of planet Earth, that the negative effects of human activity on the environment can be reversed with effort, goodwill and determination.

Britain was a very different place 15,000 years ago - home to lions, lynx, bears, wolves, bison and many more megafauna. But as its climate changed and human populations expanded, most of early Britain's largest mammals disappeared. Will advances in science and technology mean that we can one day bring these mammals back? And should we? In The Missing Lynx, palaeontologist Ross Barnett uses case studies, new fossil discoveries and biomolecular evidence to paint a picture of these lost species and to explore the ecological significance of their disappearance. He discusses how the Britons these animals shared their lives with might have viewed them and investigates why some species survived while others vanished. Barnett also looks in detail at the realistic potential of reintroductions, rewilding and even of resurrection in Britain and overseas, from the successful return of beavers in Argyll to the revolutionary Pleistocene Park in Siberia, which has already seen progress in the revival of 'mammoth steppe' grassland. As widespread habitat destruction, climate change and an ever-growing human population lead us inexorably towards the sixth extinction, this timely book explores the spaces that extinction has left unfilled. And by helping us to understand why some of our most charismatic animals are gone, Ross Barnett encourages us to look to a brighter future, one that might see these missing beasts returned to the land on which they once lived and died.
