The Life, Extinction, and Rebreeding of Quagga Zebras - Significance for Conservation (Hardcover): Peter Heywood The Life, Extinction, and Rebreeding of Quagga Zebras - Significance for Conservation (Hardcover)
Peter Heywood
R2,650 Discovery Miles 26 500 Ships in 12 - 19 working days

Quaggas were beautiful pony-sized zebras in southern Africa that had fewer stripes on their bodies and legs, and a browner body coloration than other zebras. Indigenous people hunted quaggas, portrayed them in rock art, and told stories about them. Settlers used quaggas to pull wagons and to protect livestock against predators. Taken to Europe, they were admired, exhibited, harnessed to carriages, illustrated by famous artists and written about by scientists. Excessive hunting led to quaggas' extinction in the 1880s but DNA from museum specimens showed rebreeding was feasible and now zebras resembling quaggas live in their former habitats. This rebreeding is compared with other de-extinction and rewilding ventures and its appropriateness discussed against the backdrop of conservation challenges-including those facing other zebras. In an Anthropocene of species extinction, climate change and habitat loss which organisms and habitats should be saved, and should attempts be made to restore extinct species?

In 2006, vaquita, a diminutive porpoise making its home in the Upper Gulf of California, inherited the dubious title of world’s most endangered marine mammal. Nicknamed “panda of the sea” for its small size and beguiling facial markings, vaquita have been in decline for decades, dying by the hundreds in gillnets intended for the commercially valuable fish, totoaba. When international crime cartels discovered a lucrative trade in the swim bladders of totoaba, illegal gillnetting went rampant, and now the lives of the few remaining vaquita hang in the balance. Author Brooke Bessesen takes us on a journey to Mexico’s Upper Gulf region to uncover the story. She interviewed townspeople, fishermen, politicians, scientists, and activists, teasing apart a complex story filled with villains and heroes, a story whose outcome is unclear. When diplomatic and political efforts to save the little porpoise failed, Bessesen traveled with a team of veterinary experts in a binational effort to capture the remaining ten vaquita and breed them in captivity—the only hope for their survival. In this fast-paced, soul-searing tale, she learned that there are no easy answers when extinction is profitable. Whether the rescue attempt succeeds or fails, the world must ask itself hard questions. When vaquita and the totoaba are gone, the black market will turn to the next vulnerable species. What will we do then?

The Jarawa, one of the oldest tribes of human beings in the world, may go extinct because of a road that runs through pristine forests in the Indian-administered Andaman Islands, in the Bay of Bengal, and no one seems to care. Tourists take the road each day to try and get selfies with the tribespeople, who came from what is now Botswana over 60,000 years ago. Once proud of their independence, the Jarawa are now tempted with biscuits and trinkets, as if they were exotic animals in a human safari park. They can’t survive like this. In this astonishing book, Jonathan Lawley returns to what was once a penal colony built by the British to house Indian mutineers. He asks what responsibility colonial administrators like his grandfather may have had for the sad plight of these palaeolithic hunter- gatherers, and what the Indian government should now be doing to protect them.

The Snow Leopard and the Goat - Politics of Conservation in the Western Himalayas (Hardcover): Shafqat Hussain The Snow Leopard and the Goat - Politics of Conservation in the Western Himalayas (Hardcover)

Following the downgrading of the snow leopard's status from "endangered" to "vulnerable" by the International Union for Conservation of Nature in 2017, debate has renewed about the actual number of snow leopards in the wild and the most effective strategies for coexisting with these enigmatic animals. Evidence from Pakistan and other countries in the snow leopard's home range shows that they rely heavily on human society-domestic livestock accounts for as much as 70 percent of their diet. Maintaining that the snow leopard is a "wild" animal, conservation NGOs and state agencies have enacted laws that punish farmers for attacking these predators, while avoiding engaging with efforts to mitigate the harms suffered by farmers whose herds are reduced by snow leopards. This ethnography examines the uneven distribution of costs and benefits involved in snow leopard conservation and shows that for the conservation of nature to be successful, the vision, interests, and priorities of those most affected by conservation policies-in this case, local farmers-must be addressed. A case history of Project Snow Leopard in the mountains of northern Pakistan, which inspired similar programs in India, Bhutan, Nepal, Mongolia, Afghanistan and Tajikistan, describes how the animal's food habits are studied, how elusive individuals are counted, and how a novel kind of "snow leopard insurance" has protected the species by compensating farmers for livestock losses. The Snow Leopard and the Goat demonstrates that characterizing this conflict as one between humans (farmers) and wildlife (snow leopards) is misleading, as the real conflict is between two human groups-farmers and conservationists-who see the snow leopard differently.

Where Bigfoot Walks - Crossing the Dark Divide (Paperback): Robert Michael Pyle Where Bigfoot Walks - Crossing the Dark Divide (Paperback)

R480 Discovery Miles 4 800 Ships in 10 - 15 working days

The inspiration for the film The Dark Divide starring David Cross and Debra Messing, one of America's most esteemed natural history writers takes to the hills in search of Bigfoot-and finds the wildness within ourselves. Awarded a Guggenheim Fellowship to investigate the legends of Sasquatch, Yale-trained ecologist Dr. Robert Pyle treks into the unprotected wilderness of the Dark Divide near Mount St. Helens, where he discovers both a giant fossil footprint and recent tracks. On the trail of what he thought was legend, he searches out Indians who tell him of an outcast tribe, the Seeahtiks, who had not fully evolved into humans. A handful of open-minded biologists and anthropologists counter the tabloids Pyle studies, while rogue Forest Service employees and loggers swear of a vast conspiracy to deep-six true stories of unknown, upright hominoid apes among us. He attends Sasquatch Daze, where he meets scientists, hunters, and others who have devoted their lives to the search, only to realize that "these guys don't want to find Bigfoot they want to be Bigfoot!" Since its original publication, the author's fresh experiences and finds have been added to his original work through an updated chapter. With an evaluation of recent DNA evidence from Bigfoot hair and scat, the study of speech phonemes in the "Sierra Sounds" purported Bigfoot recordings, an examination of the impact of the wildly popular Animal Planet series Bigfoot Hunters, the reemergence of the famous Bob Gimlin into the Bigfoot community, and more, Walking With Bigfoot keeps every Bigfoot enthusiast's mind wide open to one of the biggest questions in the land and brings Pyle's work on the "legend" of Bigfoot into the new century.

In Producing Predators Michael D. Wise argues that contestations between Native and non-Native people over hunting, labor, and the livestock industry drove the development of predator eradication programs in Montana and Alberta from the 1880s onward. The history of these antipredator programs was significant not only for their ecological effects but also for their enduring cultural legacies of colonialism in the Northern Rockies. By targeting wolves and other wild carnivores for extermination, cattle ranchers disavowed the predatory labor of raising domestic animals for slaughter, representing it instead as productive work. Meanwhile, federal agencies sought to purge the Blackfoot, Salish-Kootenai, and other indigenous peoples of their so-called predatory behaviors through campaigns of assimilation and citizenship that forcefully privatized tribal land and criminalized hunting and its related ritual practices. Despite these colonial pressures, Native communities resisted and negotiated the terms of their dispossession by representing their own patterns of work, food, and livelihood as productive. By exploring predation and production as fluid cultural logics for valuing labor rather than just a set of biological processes, Producing Predators offers a new perspective on the history of the American West and the modern history of colonialism more broadly.

Since the release of the documentary Blackfish in 2013, millions around the world have focused on the plight of the orca, the most profitable and controversial display animal in history. Yet, until now, no historical account has explained how we came to care about killer whales in the first place. Drawing on interviews, official records, private archives, and his own family history, Jason M. Colby tells the exhilarating and often heartbreaking story of how people came to love the ocean's greatest predator. Historically reviled as dangerous pests, killer whales were dying by the hundreds, even thousands, by the 1950s-the victims of whalers, fishermen, and even the US military. In the Pacific Northwest, fishermen shot them, scientists harpooned them, and the Canadian government mounted a machine gun to eliminate them. But that all changed in 1965, when Seattle entrepreneur Ted Griffin became the first person to swim and perform with a captive killer whale. The show proved wildly popular, and he began capturing and selling others, including Sea World's first Shamu. Over the following decade, live display transformed views of Orcinus orca. The public embraced killer whales as charismatic and friendly, while scientists enjoyed their first access to live orcas. In the Pacific Northwest, these captive encounters reshaped regional values and helped drive environmental activism, including Greenpeace's anti-whaling campaigns. Yet even as Northwesterners taught the world to love whales, they came to oppose their captivity and to fight for the freedom of a marine predator that had become a regional icon. This is the definitive history of how the feared and despised "killer" became the beloved "orca"-and what that has meant for our relationship with the ocean and its creatures.

R321 Discovery Miles 3 210 Ships in 12 - 19 working days

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

NAMED ONE OF THE BEST BOOKS OF THE YEAR by The New Yorker and Science News What happens when you try to recreate a woolly mammoth-fascinating science, or conservation catastrophe? Jurassic Park meets The Sixth Extinction in Rise of the Necrofauna, a provocative look at de-extinction from acclaimed documentarist and science writer Britt Wray, PhD. In Rise of the Necrofauna, Wray takes us deep into the minds and labs of some of the world's most progressive thinkers to find out. She introduces us to renowned futurists like Stewart Brand and scientists like George Church, who are harnessing the powers of CRISPR gene editing in the hopes of "reviving" extinct passenger pigeons, woolly mammoths, and heath hens. She speaks with Nikita Zimov, who together with his eclectic father Sergey, is creating Siberia's Pleistocene Park-a daring attempt to rebuild the mammoth's ancient ecosystem in order to save earth from climate disaster. Through interviews with these and other thought leaders, Wray reveals the many incredible opportunities for research and conservation made possible by this emerging new field. But we also hear from more cautionary voices, like those of researcher and award-winning author Beth Shapiro (How to Clone a Woolly Mammoth) and environmental philosopher Thomas van Dooren. Writing with passion and perspective, Wray delves into the larger questions that come with this incredible new science, reminding us that de-extinction could bring just as many dangers as it does possibilities. What happens, for example, when we bring an "unextinct" creature back into the wild? How can we care for these strange animals and ensure their comfort and safety-not to mention our own? And what does de-extinction mean for those species that are currently endangered? Is it really ethical to bring back an extinct passenger pigeon, for example, when countless other birds today will face the same fate? By unpacking the many biological, technological, ethical, environmental, and legal questions raised by this fascinating new field, Wray offers a captivating look at the best and worst of resurrection science.

Extinct Madagascar (Hardcover): Steven M. Goodman Extinct Madagascar (Hardcover)
Steven M. Goodman
R1,240 Discovery Miles 12 400 Ships in 12 - 19 working days

The landscapes of Madagascar have long delighted zoologists, who have discovered, in and among the island's baobab trees and thickets, a dizzying array of animals, including something approaching one hundred species of lemur. Madagascar's mammal fauna, for example, is far more diverse, and more endemic, than early explorers and naturalists ever dreamed of. But in the 2,500 or so years since the arrival of the island's first human settlers, the vast majority of its forests have disappeared, and in the wake of this loss a number of species unique to Madagascar have vanished forever into extinction.
In "Extinct Madagascar," noted scientists Steven M. Goodman and William L. Jungers explore the recent past of these land animal extinctions. Beginning with an introduction to the geologic and ecological history of Madagascar that provides context for the evolution, diversification, and, in some cases, rapid decline of the Malagasy fauna, Goodman and Jungers then seek to recapture these extinct mammals in their environs. Aided in their quest by artist Velizar Simeonovski's beautiful and haunting paintings--images of both individual species and ecosystem assemblages reproduced here in full color--Goodman and Jungers reconstruct the lives of these lost animals and trace their relationships to those still living.
Published in conjunction with an exhibition of Simeonovski's paintings set to open at the Field Museum, Chicago, in the fall of 2014, Goodman and Jungers's awe-inspiring book will serve not only as a sobering reminder of the very real threat of extinction, but also as a stunning tribute to Madagascar's biodiversity and a catalyst for further research and conservation.

In this 2008 text, two of the world's leading experts in palynology and paleobotany provide a comprehensive account of the fate of land plants during the 'great extinction' about 65 million years ago. They describe how the time boundary between the Cretaceous and Paleogene Periods (the K T boundary) is recognised in the geological record, and how fossil plants can be used to understand global events of that time. There are case studies from over 100 localities around the world, including North America, China, Russia and New Zealand. The book concludes with an evaluation of possible causes of the K T boundary event and its effects on floras of the past and present. This book is written for researchers and students in paleontology, botany, geology and Earth history, and everyone who has been following the course of the extinction debate and the K T boundary paradigm shift.

Very Short Introductions: Brilliant, Sharp, Inspiring Extinction is a natural process. In geological time there have been several periods of mass extinction. One of these periods is unfolding right now but all the evidence suggests that current extinction rates are between a hundred and a thousand times greater than the background rate. To put this in to context, a quarter of all known mammalian species is at risk. The current extinction crisis is unique, because it is caused by the impact of one species, humans, on all others. This acceleration of species loss, and the much more widespread reductions in the populations of many species, is not merely a tragedy in aesthetics, it is also a threat to the quality of human life, indeed to the entire human enterprise. Biodiversity, the diversity of life, is not only fascinating and beautiful, it is the engine of all the world's natural cycles, and the source of many of the resources on which humanity depends. Concern about biodiversity conservation is, therefore, not merely the preoccupation of a few enthusiastic naturalists - it is the lifeline business of everybody. In this Very Short Introduction, David Macdonald introduces the concept of biodiversity and the basic biological processes that it involves - evolutionary, ecological, and behavioral. He considers the various threats to biodiversity, their impacts, and some of the solutions to the problems; concluding by considering the future of biodiversity conservation. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.

R1,380 Discovery Miles 13 800 Ships in 12 - 19 working days

This collection of original essays by economists, biologists and political scientists has a common theme: that protecting species at risk while safeguarding social order is a policy challenge that entangles biology, politics, and economics. Nearly 1200 species are listed as endangered or threatened under the Endangered Species Act (ESA) of 1973; only twelve have been removed from the list. Attempts at species recovery on public and private property lead the authors to examine the political realities that define the debate: who should pay the costs and receive the benefits, and how interest group behaviour affects the nature of endangered species protection. Although the ESA directs administrative agencies to list and protect species following scientific priorities, the collection addresses the economic choices that still must be confronted. These range from the protection potential of private markets to the design of incentive schemes to encourage conservation by private landowners.

There are many hypotheses describing the interactions involved in biological invasions, but it is largely unknown whether they are backed up by empirical evidence. This book fills that gap by developing a tool for assessing research hypotheses and applying it to twelve invasion hypotheses, using the hierarchy-of-hypotheses (HoH) approach, and mapping the connections between theory and evidence. In Part 1, an overview chapter of invasion biology is followed by an introduction to the HoH approach and short chapters by science theorists and philosophers who comment on the approach. Part 2 outlines the invasion hypotheses and their interrelationships. These include biotic resistance and island susceptibility hypotheses, disturbance hypothesis, invasional meltdown hypothesis, enemy release hypothesis, evolution of increased competitive ability and shifting defence hypotheses, tens rule, phenotypic plasticity hypothesis, Darwin's naturalization and limiting similarity hypotheses and the propagule pressure hypothesis. Part 3 provides a synthesis and suggests future directions for invasion research

A detailed exploration of the variety of threats that endangered species are facing around the world, whether they are due to human impact or so-called natural causes. Endangered species is a more complex issue and problem than it may seem on the surface. What species are endangered, and what is causing them to become vulnerable to population decline? How can essential industries such as farming, housing development, and manufacturing continue to thrive without harming flora and fauna that are protected? Are current efforts adequate or should more be done to protect endangered species? And who should be responsible for the substantial costs of working to save endangered species? Endangered Species: A Reference Handbook begins with an introduction that addresses major threats and extinctions in history, discusses the geographical and cultural contexts in which these incidents happened, highlights other key moments along the endangered species timeline, and clearly shows why the topic of endangered species matters. The following sections examine an unbiased synthesis of classic and contemporary studies that inform the issue of endangered species and outline the most controversial events related to endangered species and the actions that have been taken to address them. The book also presents perspective essays by scholars, activists, and other experts to provide diverse informed opinions on the issue of endangered species and includes a data and documents chapter that applies research finding to provide answers to questions like what species are most likely to become endangered in the future and which practices have historically been the most effective at protecting vulnerable species.

Beginning in 1984, Eric Dinerstein led a team directly responsible for the recovery of the greater one-horned rhinoceros in the Royal Chitwan National Park in Nepal, where the population had once declined to as few as 100 rhinos. The Return of the Unicorns is an account of what it takes to save endangered large mammals. In its pages, Dinerstein outlines the multifaceted recovery program-structured around targeted fieldwork and scientific research, effective protective measures, habitat planning and management, public-awareness campaigns, economic incentives to promote local guardianship, and bold, uncompromising leadership-that brought these extraordinary animals back from the brink of extinction. In an age when scientists must also become politicians, educators, fund-raisers, and activists to safeguard the subjects that they study, Dinerstein's inspiring story offers a successful model for large-mammal conservation that can be applied throughout Asia and across the globe.
