An insightful exploration of the iconic Galapagos tortoises, and how their fate is inextricably linked to our own in a rapidly changing world The Galapagos archipelago is often viewed as a last foothold of pristine nature. For sixty years, conservationists have worked to restore this evolutionary Eden after centuries of exploitation at the hands of pirates, whalers, and island settlers. This book tells the story of the islands' namesakes-the giant tortoises-as coveted food sources, objects of natural history, and famous icons of conservation and tourism. By doing so, it brings into stark relief the paradoxical, and impossible, goal of conserving species by trying to restore a past state of prehistoric evolution. The tortoises, Elizabeth Hennessy demonstrates, are not prehistoric, but rather microcosms whose stories show how deeply human and nonhuman life are entangled. In a world where evolution is thoroughly shaped by global history, Hennessy puts forward a vision for conservation based on reckoning with the past, rather than trying to erase it.
One of the greatest unmet challenges in conservation biology is the genetic management of fragmented populations of threatened animal and plant species. More than a million small, isolated, population fragments of threatened species are likely suffering inbreeding depression and loss of evolutionary potential, resulting in elevated extinction risks. Although these effects can often be reversed by re-establishing gene flow between population fragments, managers very rarely do this. On the contrary, genetic methods are used mainly to document genetic differentiation among populations, with most studies concluding that genetically differentiated populations should be managed separately, thereby isolating them yet further and dooming many to eventual extinction! Many small population fragments are going extinct principally for genetic reasons. Although the rapidly advancing field of molecular genetics is continually providing new tools to measure the extent of population fragmentation and its genetic consequences, adequate guidance on how to use these data for effective conservation is still lacking. This accessible, authoritative text is aimed at senior undergraduate and graduate students interested in conservation biology, conservation genetics, and wildlife management. It will also be of particular relevance to conservation practitioners and natural resource managers, as well as a broader academic audience of conservation biologists and evolutionary ecologists.
On the Tibetan Plateau, there are wild yaks with blood cells thinner than horses' by half, enabling the endangered yaks to survive at 40 below zero and in the lowest oxygen levels of the mountaintops. But climate change is causing the snow patterns here to shift, and with the snows, the entire ecosystem. Food and water are vaporizing in this warming environment, and these beasts of ice and thin air are extraordinarily ill-equipped. A journey into some of the most forbidding landscapes on earth, Joel Berger's Extreme Conservation is an eye-opening, steely look at what it takes for animals like these to live at the edges of existence. But more than this, it is a revealing exploration of how climate change and people are affecting even the most far-flung niches of our planet. Berger's quest to understand these creatures' struggles takes him to some of the most remote corners and peaks of the globe: across Arctic tundra and the frozen Chukchi Sea to study muskoxen, into the Bhutanese Himalayas to follow the rarely-sighted takin, and through the Gobi Desert to track the proboscis-swinging saiga. Known as much for his rigorous, scientific methods of developing solutions to conservation challenges as for his penchant for donning moose and polar bear costumes to understand the mindsets of his subjects more closely, Berger is a guide bar none. He is a scientist and storyteller who has made his life working with desert nomads, in zones that typically require Sherpas and oxygen canisters. Recounting animals as charismatic as their landscapes are extreme, Berger's unforgettable tale carries us with humor and expertise to the ends of the earth and back. But as his adventures show, the more adapted a species has become to its particular ecological niche, the more devastating climate change can be. Life at the extremes is more challenging than ever, and the need for action, for solutions, has never been greater.
This is an abridged and updated version of the award-winning publication 'Virginia's Endangered Species' (1991). An introduction summarises Virginia's natural habitats, conservation laws, and the responsibilities of the various state agencies involved in the conservation of biotic diversity in the Commonwealth. Most of the book consists of one-page descriptions and discussions of those species of plant and animal that are officially listed as endangered or threatened in Virginia. A beautiful colour photograph and map of occurrence is provided for almost every species. This guide is written in a style and format that will be enjoyed and understood by both professionals and laypersons. Its size, conciseness, and price make it an especially versatile, accessible, and useable reference and field tool for all who are interested in understanding and protecting Virginia's vulnerable natural heritage. The entries are from accounts prepared by more than 80 biologists from throughout Virginia. It contains the most current information available in printed form on the subject of vulnerable species in Virginia.
Darwin's "Origin of Species" and Dobzhansky's "Genetics and the Origin of Species" have been the cornerstones of modern evolutionary and population genetic theory for the past hundred years, but in the twenty-first century, biologists will face graver problems of extinction. In this collection, a team of leading biologists demonstrates why the burgeoning field of conservation biology must continue to rely on the insights of population genetics if we are to preserve the diversity of living species. Technological and theoretical developments throughout the 1990s have allowed for important new insights into how populations have evolved in response to past selection pressures, while providing a broad new understanding of the genetic structure of natural populations. The authors explore these advances and argue for the applicability of new genetic methods in conservation biology. The volume covers such topics as the reasons for extinctions, the best ways to measure biodiversity, and the benefits and drawbacks of policies like captive breeding. "Genetics and the Extinction of Species" is a rich source of information for biologists and policymakers who want to learn more about the host of tools, theories, and approaches available for conserving biodiversity. In addition to the editors, the contributors to the volume are William Amos, Rebecca Cann, Kathryn Rodriguez-Clark, Leslie Douglas, Leonard Freed, Paul Harvey, Kent Holsinger, Russell Lande, and Helen Steers.
The inspiring true story of "the Indiana Jones of conservation." --"The Guardian "(UK) When Lawrence Anthony, author of "The Elephant Whisperer"," "
cared for not only elephants but other types of wildlife, including
rhinos, on his nature reserve. So when he learned that there were
only a handful of northern white rhinos left in the wild, living in
an area of the Congo controlled by the infamous Lord's Resistance
Army, he was determined to save them from extinction. If the world
lost this subspecies of rhinoceros, it would be the largest
landmammal since the woolly mammoth to go extinct, a tragedy for
those who care about the world's endangered species. What followed was an extraordinary adventure, as Anthony headed into the jungle to ask the rebels to help protect the rhino. Sometimes funny, sometimes moving, and always exciting, " The Last Rhinos "tells the story of his fight to save these remarkable creatures.
If you could bring back just one animal from the past, what would you choose? It can be anyone or anything from history, from the King of the Dinosaurs, T. rex, to the King of Rock `n' Roll, Elvis Presley, and beyond. De-extinction - the ability to bring extinct species back to life - is fast becoming reality. Around the globe, scientists are trying to de-extinct all manner of animals, including the woolly mammoth, the passenger pigeon and a bizarre species of flatulent frog. But de-extinction is more than just bringing back the dead. It's a science that can be used to save species, shape evolution and sculpt the future of life on our planet. In Bring Back the King, scientist and comedy writer Helen Pilcher goes on a quest to identify the perfect de-extinction candidate. Along the way, she asks if Elvis could be recreated from the DNA inside a pickled wart, investigates whether it's possible to raise a pet dodo, and considers the odds of a 21st century Neanderthal turning heads on public transport. Pondering the practicalities and the point of de-extinction, Bring Back the King is a witty and wry exploration of what is bound to become one of the hottest topics in conservation - if not in science as a whole - in the years to come. READ THIS BOOK - the King commands it.
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.
GON·ZO·VA·TION 1. alternative conservation through the act of gonzovating and exhibiting compassion for the natural world. 2. the protection, preservation, management, or restoration of wildlife and of natural resources to include forests, earth, and water. GON·ZO·VA·TION·IST 1. an alternative conservationist. 2. a person who makes sense from the nonsense Over the course of three remarkable books packed with wit, warmth, and extraordinary art, Ralph Steadman and his co-conspirator, author and film-maker Ceri Levy, sought to change the way we look at conservation. The first, Extinct Boids, featured vanished birds like the Dodo, the Great Auk, and the Carolina Parakeet, with a variety of boids like the Gob Swallow and the Needless Smut to keep them company. This was followed by Nextinction, where the focus switched to birds that are still just about with us, such as the Giant Ibis and Kakapo, along with classic Steadman creations such as the Unsociable Lapwing. The series was completed by Critical Critters, featuring critically endangered mammals, insects, fish, lizards and trees – a stunning collection, with a strong conservation message. This box set brings the three elements of the Gonzovation trilogy together for the first time. These books form a body of art of rare brilliance. Packed with trademark Steadman humour, they also represent a powerful and compelling appeal for change in the way we treat the animals that share our planet. All of us can follow the gonzovationist path – let The Gonzovation Trilogy be your guide.
For the last twenty years, The Destruction of the Bison has been an essential work in environmental history. Andrew C. Isenberg offers a concise analysis of the near-extinction of the North American bison population from an estimated 30 million in 1800 to fewer than 1000 a century later. His wide-ranging, interdisciplinary study carefully considers the multiple causes, cultural and ecological, of the destruction of the species. The twentieth-anniversary edition includes a new foreword connecting this seminal work to developments in the field - notably new perspectives in Native American history and the rise of transnational history - and placing the story of the bison in global context. A new afterword extends the study to the twenty-first century, underlining the continued importance of this ground-breaking text for current, and future, students and scholars.
The editors utilize their 50 years of combined experience in

A leading figure in the emerging field of extinction studies, Thom van Dooren puts philosophy into conversation with the natural sciences and his own 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.
Lively, colorful, and skillfully made fabric "portraits" of 182 endangered species bring them to real, vibrant life. Each portrait features fascinating animal and plant facts from rescuers, scientists, conservationists, and more: where they live, what their superpowers are, why they are at risk, and how we can help. Dedicated and passionate people who work to protect endangered species share details of their roles and specialties, the planning behind conservation measures, threats to healthy habitats, and inspiring success stories. This book fosters eco-awareness and responsibility with a hopeful and positive tone, not only educating but inspiring action. A percentage of money earned by the author from the sale of this book will be donated to the Sea Turtle Conservancy and to the WILD Foundation.
Could extinct species, like mammoths and passenger pigeons, be brought back to life? The science says yes. In How to Clone a Mammoth, Beth Shapiro, evolutionary biologist and pioneer in "ancient DNA" research, walks readers through the astonishing and controversial process of de-extinction. From deciding which species should be restored, to sequencing their genomes, to anticipating how revived populations might be overseen in the wild, Shapiro vividly explores the extraordinary cutting-edge science that is being used--today--to resurrect the past. Journeying to far-flung Siberian locales in search of ice age bones and delving into her own research--as well as those of fellow experts such as Svante Paabo, George Church, and Craig Venter--Shapiro considers de-extinction's practical benefits and ethical challenges. Would de-extinction change the way we live? Is this really cloning? What are the costs and risks? And what is the ultimate goal? Using DNA collected from remains as a genetic blueprint, scientists aim to engineer extinct traits--traits that evolved by natural selection over thousands of years--into living organisms. But rather than viewing de-extinction as a way to restore one particular species, Shapiro argues that the overarching goal should be the revitalization and stabilization of contemporary ecosystems. For example, elephants with genes modified to express mammoth traits could expand into the Arctic, re-establishing lost productivity to the tundra ecosystem. Looking at the very real and compelling science behind an idea once seen as science fiction, How to Clone a Mammoth demonstrates how de-extinction will redefine conservation's future.
The Great Auk is one of the world's most famous extinct birds. This curious seabird was flightless, stood upright like a human, and sported an enormous beak. In this fascinating book, Jeremy A. Gaskell takes the reader on a tour of some of the wildest and coldest places on earth as he tries to uncover the facts behind its disappearance, and the reasons why attempts to save it were in vain.
Would you ask a honeybee to point at a screen and recognise a facial expression? Or ask an elephant to climb a tree? While humans and non-human species may inhabit the same world, it's likely that our perceptual worlds differ significantly. Emphasising Uexkull's concept of 'umwelt', this volume offers practical advice on how animal cognition can be successfully tested while avoiding anthropomorphic conclusions. The chapters describe the capabilities of a range of animals - from ants, to lizards to chimpanzees - revealing how to successfully investigate animal cognition across a variety of taxa. The book features contributions from leading cognition researchers, each offering a series of examples and practical tips drawn from their own experience. Together, the authors synthesise information on current field and laboratory methods, providing researchers and graduate students with methodological advice on how to formulate research questions, design experiments and adapt studies to different taxa. |
