Extinct - Artistic Impressions of Our Lost Wildlife (Hardcover): Benjamin Gray Extinct - Artistic Impressions of Our Lost Wildlife (Hardcover)
Benjamin Gray
R2,005 Discovery Miles 20 050 Ships in 9 - 17 working days

Australia is home to an incredible diversity of native animals. While Australian animals are among the most unique in the world, they are also among the most endangered, with hundreds currently on the brink of extinction. We must act quickly if we are to save these species, as once gone, they are gone forever. Extinct is a collection of artworks from established and emerging Australian fine artists, each depicting an Australian animal that has already, for various reasons, tumbled over the edge into extinction. Extinct laments their loss, but also celebrates their former existence, diversity and significance. The stunning artworks are accompanied by stories of each animal, highlighting the importance of what we have lost, so that we appreciate what we have not lost yet. FEATURES Features original artworks by over 40 of Australia's contemporary and most distinguished artists, including those from Indigenous and migrant backgrounds and artists with intellectual disabilities. Highlights many species that have never been depicted or photographed before, or those for which only a handful of visual references exist. Presents physical descriptions and meticulously researched, fascinating facts about the behaviour and biology of these lost species. Includes previously unheard stories of these extinct species, drawn from Indigenous histories, colonial commerce and European settlement. Extinct features artworks from Bernard Ollis, Brook Garru Andrew, Bruce Goold, Chris O'Doherty (AKA Reg Mombassa), Sally Robinson, Eliza Gosse and Jenny Watson.

R4,640 Discovery Miles 46 400 Ships in 12 - 19 working days

Whales and dolphins are icons for the conservation movement. They are the most conspicuous ambassadors for entire marine ecosystems and possibly even for the biosphere as a whole. Concurrent with our realisation of impending threats to their environment is a growing scientific understanding of the social and cognitive complexity of many of these species. This book brings together experts in the relevant diverse fields of cetacean research, to provide authoritative descriptions of our current knowledge of the complex behaviour and social organization of whales and dolphins. The authors consider this new information in the context of how different human cultures from around the world view cetaceans and their protection, including attitudes to whaling. They show how new information on issues such as cetacean intelligence, culture and the ability to suffer, warrants a significant shift in global perceptions of this group of animals and how these changes might be facilitated to improve conservation and welfare approaches.

The Biology and Ecology of Streams and Rivers (Paperback, 2 Revised Edition): Alan Hildrew, Paul Giller The Biology and Ecology of Streams and Rivers (Paperback, 2 Revised Edition)
Alan Hildrew, Paul Giller
R1,397 Discovery Miles 13 970 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.

R1,132 Discovery Miles 11 320 Ships in 12 - 19 working days

The most up-to-date and authoritative resource on the biology and evolution of solitary bees While social bees such as honey bees and bumble bees are familiar to most people, they comprise less than 10 percent of all bee species in the world. The vast majority of bees lead solitary lives, surviving without the help of a hive and using their own resources to fend off danger and protect their offspring. This book draws on new research to provide a comprehensive and authoritative overview of solitary bee biology, offering an unparalleled look at these remarkable insects. The Solitary Bees uses a modern phylogenetic framework to shed new light on the life histories and evolution of solitary bees. It explains the foraging behavior of solitary bees, their development, and competitive mating tactics. The book describes how they construct complex nests using an amazing variety of substrates and materials, and how solitary bees have co-opted beneficial mites, nematodes, and fungi to provide safe environments for their brood. It looks at how they have evolved intimate partnerships with flowering plants and examines their associations with predators, parasites, microbes, and other bees. This up-to-date synthesis of solitary bee biology is an essential resource for students and researchers, one that paves the way for future scholarship on the subject. Beautifully illustrated throughout, The Solitary Bees also documents the critical role solitary bees play as crop pollinators, and raises awareness of the dire threats they face, from habitat loss and climate change to pesticides, pathogens, parasites, and invasive species.

Plant Conservation - An Ecosystem Approach (Paperback): Alan Hamilton Plant Conservation - An Ecosystem Approach (Paperback)
Alan Hamilton
R1,804 Discovery Miles 18 040 Ships in 12 - 19 working days

In this, the latest in the People and Plants series, plant conservation is described in the context of livelihoods and development, and ways of balancing the conservation of plant diversity with the use of plants and the environment for human benefit are discussed. A central contention in this book is that local people must be involved if conservation is to be successful. Also examined are ways of prioritizing plants and places for conservation initiatives, approaches to in situ and ex situ conservation, and how to approach problems of unsustainable harvesting of wild plants. Roles for botanists, foresters, sociologists, development workers and others are discussed. This book acts as a unifying text for the series, integrating case studies and methodologies considered in previous volumes and pointing out in a comprehensive, accessible volume the valuable lessons to be learned.

Carnivoran Ecology - The Evolution and Function of Communities (Paperback): Steven W. Buskirk Carnivoran Ecology - The Evolution and Function of Communities (Paperback)
Steven W. Buskirk
R1,369 Discovery Miles 13 690 Ships in 9 - 17 working days

These charismatic mammals, which include dogs, cats, hyenas, weasels, mongooses, seals, sea lions and bears, have always held special importance to humans throughout history and continue to do so today. In recent decades, the emergence of new technologies has completely transformed our knowledge of how carnivorans interact with their environments and consequently reshaped our view of carnivoran ecology. This unique synthesis uses examples from a diverse and expanding carnivoran literature, drawing from all carnivoran families and spanning the world's oceans and continents, to produce a clearly written and richly illustrated book that reviews our current state of knowledge of carnivoran ecology. It addresses all levels of biological organization and function, from genes to enzymes, organisms, populations, and ecosystems. Special attention is given to how carnivoran species interact with their prey, each other, and humans. There is an emphasis on community interactions and their importance in carnivoran evolution, showing how evolutionary constraints (morphological, physiological, and behavioral) structure communities today. The book's approach is strongly comparative, contrasting herbivores with carnivores, predators with scavengers, and cats with dogs. Carnivorans play important roles in many high-profile conservation cases, either as species of concern or agents of endangerment, and their importance is demonstrated in both contexts. Carnivoran Ecology is an accessible advanced textbook aimed principally at senior undergraduate and graduate students taking courses in carnivore ecology, as well as a broad audience of professional academics (especially carnivore and mammalian biologists), researchers, and practitioners working in both governmental and non-governmental organizations. A significant secondary market will exist amongst the large amateur naturalist community including those wishing to explore the ecological and evolutionary links between domestic carnivorans (dogs, cats, ferrets etc.) and their wild counterparts.

An unmissable journey into the hidden worlds beneath our feet.

From the vast underground mycelial networks by which trees communicate to the ice-blue depths of glacial moulins, and from North Yorkshire to the Lofoten Islands, Robert Macfarlane traces a voyage through the worlds beneath our feet.

He reaches back into the deep history of the planet, through the layers of rock and ancient buried objects, and forward to the future, the legacy of the anthropocene and the world we bequeath our descendants.

Underland is Macfarlane at his dazzling best - the lyrical, the political and the philosophical come together in this profound exploration of the relationship between landscape and the human heart.

Sacred Natural Sites - Conserving Nature and Culture (Paperback): Bas Verschuuren, Jeffrey McNeely, Gonzalo Oviedo, Robert Wild Sacred Natural Sites - Conserving Nature and Culture (Paperback)
Bas Verschuuren, Jeffrey McNeely, Gonzalo Oviedo, Robert Wild
R1,841 Discovery Miles 18 410 Ships in 12 - 19 working days

Sacred Natural Sites are the world's oldest protected places. This book focuses on a wide spread of both iconic and lesser known examples such as sacred groves of the Western Ghats (India), Sagarmatha /Chomolongma (Mt Everest, Nepal, Tibet - and China), the Golden Mountains of Altai (Russia), Holy Island of Lindisfarne (UK) and the sacred lakes of the Niger Delta (Nigeria). The book illustrates that sacred natural sites, although often under threat, exist within and outside formally recognised protected areas, heritage sites. Sacred natural sites may well be some of the last strongholds for building resilient networks of connected landscapes. They also form important nodes for maintaining a dynamic socio-cultural fabric in the face of global change. The diverse authors bridge the gap between approaches to the conservation of cultural and biological diversity by taking into account cultural and spiritual values together with the socio-economic interests of the custodian communities and other relevant stakeholders.

Heatstroke - Nature in an Age of Global Warming (Hardcover, 3rd Ed.): Anthony D. Barnosky Heatstroke - Nature in an Age of Global Warming (Hardcover, 3rd Ed.)
Anthony D. Barnosky
R972 Discovery Miles 9 720 Ships in 12 - 19 working days

How is wildlife adapting to climate change? In 2006, one of the hottest years on record, a 'pizzly' was discovered near the top of the world. Half polar bear, half grizzly, this never-before-seen animal might be dismissed as a fluke of nature. Anthony Barnosky instead sees it as a harbinger of things to come. In "Heatstroke", the renowned paleoecologist shows how global warming is fundamentally changing the natural world and its creatures. While melting ice may have helped produce the pizzly, climate change is more likely to wipe out species than to create them. Plants and animals that have followed the same rhythms for millennia are suddenly being confronted with a world they're unprepared for - and adaptation usually isn't an option. This is not the first time climate change has dramatically transformed Earth. Barnosky draws connections between the coming centuries and the end of the last ice age, when mass extinctions swept the planet. The differences now are that climate change is faster and hotter than past changes, and for the first time humanity is driving it. Which means this time we can work to stop it. No one knows exactly what nature will come to look like in this new age of global warming. But "Heatstroke" gives us a haunting portrait of what we stand to lose and the vitality of what can be saved.

R2,427 Discovery Miles 24 270 Ships in 12 - 19 working days

Wildlife Management and Conservation presents a clear overview of the management and conservation of animals, their habitats, and how people influence both. The relationship among these three components of wildlife management is explained in chapters written by leading experts and is designed to prepare wildlife students for careers in which they will be charged with maintaining healthy animal populations; finding ways to restore depleted populations while reducing overabundant, introduced, or pest species; and managing relationships among various human stakeholders. Topics covered in this book include: the definitions of wildlife and management; human dimensions of wildlife management; animal behavior; predator-prey relationships; structured decision making; issues of scale in wildlife management; wildlife health; historical context of wildlife management and conservation; hunting and trapping; nongame species; nutrition ecology; water management; climate change; and conservation planning.

Around the World in 80 Species - Exploring the Business of Extinction (Paperback): Jill Atkins, Barry Atkins Around the World in 80 Species - Exploring the Business of Extinction (Paperback)
Jill Atkins, Barry Atkins
R1,152 Discovery Miles 11 520 Ships in 12 - 19 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.

The Missing Lynx - The Past and Future of Britain's Lost Mammals (Paperback): Ross Barnett The Missing Lynx - The Past and Future of Britain's Lost Mammals (Paperback)
Ross Barnett 1
R341 Discovery Miles 3 410 Ships in 12 - 19 working days

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.

Thom Van Dooren
R599 R558 Discovery Miles 5 580 Save R41 (7%) Ships in 12 - 19 working days

A leading figure in the emerging field of extinction studies, Thom van Dooren puts philosophy into conversation with the natural sciences and his ethnographic encounters to vivify the cultural and ethical significance of modern-day extinctions. Unlike other meditations on the subject, Flight Ways incorporates the particularities of real animals and their worlds, drawing philosophers, natural scientists, and general readers into the experience of living among and losing biodiversity. Each chapter of Flight Ways focuses on a different species or group of birds: North Pacific albatrosses, Indian vultures, an endangered colony of penguins in Australia, Hawaiian crows, and the iconic whooping cranes of North America. Written in eloquent and moving prose, the book takes stock of what is lost when a life form disappears from the world-the wide-ranging ramifications that ripple out to implicate a number of human and more-than-human others. Van Dooren intimately explores what life is like for those who must live on the edge of extinction, balanced between life and oblivion, taking care of their young and grieving their dead. He bolsters his studies with real-life accounts from scientists and local communities at the forefront of these developments. No longer abstract entities with Latin names, these species become fully realized characters enmeshed in complex and precarious ways of life, sparking our sense of curiosity, concern, and accountability toward others in a rapidly changing world.

Coral Reefs: Tourism, Conservation and Management (Paperback): Bruce Prideaux, Anja Pabel Coral Reefs: Tourism, Conservation and Management (Paperback)
Bruce Prideaux, Anja Pabel
R1,506 Discovery Miles 15 060 Ships in 12 - 19 working days

Coral reefs are an important tourism resource for many coastal and island destinations and generate a range of benefits to their local communities, including as a food source, income from tourism, employment and recreational opportunities. However, coral reefs are under increasing threat from climate change and related impacts such as coral bleaching and ocean acidification. Other anthropogenic stresses include over-fishing, anchor damage, coastal development, agricultural run-off, sedimentation and coral mining. This book adopts a multidisciplinary approach to review these issues as they relate to the sustainable management of coral reef tourism destinations. It incorporates coral reef science, management, conservation and tourism perspectives and takes a global perspective of coral reef tourism issues covering many of the world's most significant coral reef destinations. These include the Great Barrier Reef and Ningaloo Reef in Australia, the Red Sea, Pacific Islands, South East Asia, the Maldives, the Caribbean islands, Florida Keys and Brazil. Specific issues addressed include climate change, pollution threats, fishing, island tourism, scuba diving, marine wildlife, governance, sustainability, conservation and community resilience. The book also issues a call for more thoughtful development of coral reef experiences where the ecological needs of coral reefs are placed ahead of the economic desires of the tourism industry.

More than 999 of every 1,000 species that have ever lived on the planet have become extinct. As part of evolution, extinction of the old allows emergence of the new. It is integral to the Earth's continually changing range and richness of life-forms. Extinction: not the end of the world? is a highly readable introduction to the causes of extinction, the different types of extinction and how relevant it is to the world today. The book discusses today's key issues, from biodiversity and conservation to the threat of human extinction, as well as exploring the major extinction events of the past and explaining how scientists know all this. Throughout the book there are engaging extinction case studies from around the world showing, for example, how local extinctions such as the large blue butterfly can be reversed. Presenting the latest research in an accessible and engaging way, this is a complete introduction to an important and often complex subject. The book is published to accompany the major new exhibition of the same name which opens at the Natural History Museum, London, in February 2013.

Great White sharks, attracted by an offshore seal colony, have brought success to the adjacent fishing village of Gansbaai along the southern African coast. A flourishing shark cage diving industry has sprung up, bringing jobs and money, and so benefiting almost the entire community. Tourists come from far and near to experience the thrill of a real-life brush with the legendary ‘Jaws’. Shark Town, as it has become known, is booming. Then one day, the sharks disappear. Slowly at first, but with gathering momentum, the word spreads: cage diving off Gansbaai can no longer promise the thrill of an encounter. The crowds thin, the boats remain at their moorings, and the once bustling community waits as their livelihoods tail off. Entrepreneurs and scientists alike are baffled.

But it’s not long before shark carcasses start washing up on the beaches. These, together with some coincidental sightings of another apex predator in the vicinity, are the first leads to the possible causes and culprits. Against the clamour and thrill of the cage-diving season in full swing, Richard Peirce visits the unfolding drama and explores what’s behind these strange events.

Integrating Biological Control into Conservation Practice (Hardcover): R Van Driesche Integrating Biological Control into Conservation Practice (Hardcover)
R Van Driesche
R2,664 Discovery Miles 26 640 Ships in 12 - 19 working days

Invasive species have a critical and growing effect upon natural areas. They can modify, degrade, or destroy wildland ecosystem structure and function, and reduce native biodiversity. Landscape-level solutions are needed to address these problems. Conservation biologists seek to limit such damage and restore ecosystems using a variety of approaches. One such approach is biological control: the deliberate importation and establishment of specialized natural enemies, which can address invasive species problems and which should be considered as a possible component of restoration. Biological control can be an effective tool against many invasive insects and plants but it has rarely been successfully employed against other groups. Safety is of paramount concern and requires that the natural enemies used be specialized and that targeted pests be drivers of ecological degradation. While modern approaches allow species to be selected with a high level of security, some risks do remain. However, as in all species introductions, these should be viewed in the context of the risk of failing to reduce the impact of the invasive species. This unique book identifies the balance among these factors to show how biological control can be integrated into ecosystem restoration as practiced by conservation biologists. Jointly developed by conservation biologists and biological control scientists, it contains chapters on matching tools to management goals; tools in action; measuring and evaluating ecological outcomes of biological control introductions; managing conflict over biological control; and includes case studies as well as an ethical framework for integrating biological control and conservation practice. Integrating Biological Control into Conservation Practice is suitable for graduate courses in invasive species management and biological control, as well as for research scientists in government and non-profit conservation organizations.

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.

R4,476 Discovery Miles 44 760 Ships in 12 - 19 working days

In the 1950s biologists became alarmed by the plight of Africa's wildlife. Since then they have sought to arrest its decline, but increasing competition between wild fauna and expanding human populations shows that protection alone has been inadequate. The conservationists' position and strategies have been progressively eroded: large-scale game cropping schemes have failed to produce expected revenues, the consequences of the tourist industry have been unexpectedly detrimental, and educational programs have rarely convinced rural Africans to conserve resources. Dr. Marks argues that the management and conservation of wild animals in Third World countries must include cultural as well as biological dimensions and that changes in human social systems will be necessary to sustain wildlife and the environmental processes. He describes indigenous attempts to manage wildlife and suggests new research initiatives that would lead to wildlife policies more in keeping with human development needs and with the realities of the rural countryside.

On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America's greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them (with as many as forty-three bears sighted in a single day), and thousands of people come to watch in person or on the National Park Service's popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous in three parts. The first forms an ecological history of the region, from its dormancy 30,000 years ago to the volcanic events that transformed it into the Valley of Ten Thousand Smokes. The central and longest section is a deep dive into the lives of the wildlife along the Brooks River, especially the bears and salmon. Readers will learn about the bears' winter hibernation, mating season, hunting rituals, migration patterns, and their relationship with Alaska's changing environment. Finally, the book explores the human impact, both positive and negative, on this special region and its wild population.

Why has Canada been unable to achieve any of its climate-change targets? Part of the reason is that emissions in two provinces, Alberta and Saskatchewan - already about half the Canadian total when taken together - have been steadily increasing as a result of expanding oil and gas production. Declining emissions in other provinces, such as Ontario, Quebec, Nova Scotia, and New Brunswick, have been cancelled out by those western increases. The ultimate explanation for Canadian failure lies in the differing energy interests of the western and eastern provinces, overlaid on the confederation fault-line of western alienation. Climate, energy, and national unity form a toxic mix. How can Ottawa possibly get all the provinces moving in the same direction of decreasing emissions? To answer this question, Douglas Macdonald explores the five attempts to date to put in place coordinated national policy in the fields of energy and climate change - from Pierre Trudeau's ill-fated National Energy Program to Justin Trudeau's bitterly contested Pan-Canadian program - analysing and comparing them for the first time. Important new insights emerge from this analysis which, in turn, provide the basis for a new approach. Carbon Province, Hydro Province is a major contribution to the vital question of how our federal and provincial governments can effectively work together and thereby for the first time achieve a Canadian climate-change target.
