In Plants and the K-T Boundary, 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 recognized 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.
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.
The Rise, the Fall, and the Recovery of Southeast Asia's Minidragons offers a comprehensive study of recent Asian economic history. As the global economy adjusts to an increasing Asian presence, David Hollingsworth examines specific case models from the 1990s to draw conclusions, create paradigms, and prepare guidelines for the future. With studies ranging from Taiwan to Malaysia and an in-depth analysis of the Asian Financial Crisis of 1997-1998, this is one of the most in-depth studies of contemporary Asian economic history. With clear focus and a wide range, Hollingsworth shows the relevance of recent history to the current economic situations. Contract principle is essentially the driving force that propelled East Asia to engage in a series of policies that were responsible for its economic growth and sustainability since the late 1950s. The book discusses such growth and examines the economic history of this period. It examines the move from Import-Substitution-Industrialization to Export-Orientation and the forces leading to the subsequent Asian Financial Crisis of 1997-1998. The book applies a structural investigation to case studies of: Taiwan, Singapore, Thailand, Indonesia, and Malaysia. It concludes by shaping the historical lessons into a vision for the future.
The California condor Flying on wings nearly ten feet wide from tip to tip, these birds thrived on the carcasses of animals like woolly mammoths. Then, as humans began dramatically reshaping North America, the continent's largest flying land bird started disappearing. By the beginning of the twentieth century, extinction seemed inevitable. But small groups of passionate individuals refused to allow the condor to fade away, even as they fought over how and why the bird was to be saved. Scientists, farmers, developers, bird lovers, and government bureaucrats argued bitterly and often, in the process injuring one another and the species they were trying to save. In the late 1980s, the federal government made a wrenching decision -- the last remaining wild condors would be caught and taken to a pair of zoos, where they would be encouraged to breed with other captive condors. Livid critics called the plan a recipe for extinction. After the zoo-based populations soared, the condors were released in the mountains of south-central California, and then into the Grand Canyon, Big Sur, and Baja California. Today the giant birds are nowhere near extinct. The giant bird with "one wing in the grave" appears to be recovering, even as the wildlands it needs keep disappearing. But the story of this bird is more than the story of a vulture with a giant wingspan -- it is also the story of a wild and giant state that has become crowded and small, and of the behind-the-scenes dramas that have shaped the environmental movement. As told by John Nielsen, an environmental journalist and a native Californian, this is a fascinating tale of survival.
Of the forty mammal species known to have vanished in the world in the last 200 years, almost half have been Australian. Our continent has the worst record of mammal extinctions, with over 65 mammal species having vanished in the last 50 000 years. It began with the great wave of megafauna extinctions in the last ice-age, and continues today, with many mammal species vulnerable to extinction. The question of why mammals became extinct, and why so many became extinct in Australia has been debated by experts for over a century and a half and we are no closer to agreement on the causes. This book introduces readers to the great mammal extinction debate. Chris Johnson takes us on a detective-like tour of these extinctions, uncovering how, why and when they occurred.

A vast and previously undisclosed underground economy exists in the United States. The products bought and sold: animals. In "Animal Underworld," veteran investigative journalist Alan Green exposes the sleazy, sometimes illegal web of those who trade in rare and exotic creatures. Green and The Center for Public Integrity reveal which American zoos and amusement parks dump their "surplus" animals on the middlemen adept at secretly redirecting them into the private pet trade. We're taken to exotic-animal auctions, where the anonymous high bidders are often notorious dealers, hunting-ranch proprietors, and profit-minded charlatans masquerading as conservationists. We visit some of the nation's most prestigious universities and research laboratories, whose diseased monkeys are "laundered" through this same network of breeders and dealers until they finally reach the homes of unsuspecting pet owners. And we meet the men and women who make their living by skirting through loopholes in the law, or by ignoring the law altogether. For anyone who cares about animals; for pet owners, zoo-goers, wildlife conservationists, and animal welfare advocates, "Animal Underworld" is gripping, shocking reading.
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.
Blending scientific and legal expertise, Kunich proves that a devastating ecological crisis is imminent or even underway already, and that conservation law has yet to catch up with biological science. He challenges readers with a hotspots wager, arguing that he have vastly more to gain than lose by legally protecting biological hotspots, and that foregoing them in favor of the relatively minor and immediate returns arising from their devastation is both foolish and, ultimately, dangerous. Legal thought lags behind modern science in focusing on and setting priorities for global conservation. An extinction spasm is imminent, many scientists argue, due to the ongoing global devastation of biological hotspots, home to a disproportionate share of all life forms, including perhaps millions of unknown species. These hotspots have already lost 88 percent of their primary vegetation and are likely to lose much more, yet few legal measures exist to protect them. Environmental legal protections are often incomprehensive and feebly enforced. Even worse, 62 percent of all hotspots are unprotected. Kunich provides a brief history and science of extinction. He discusses the importance of saving species from extinction and analyzes the legal measures directed toward preserving biodiversity in nations that harbor hotspots.
A great many species are threatened by the expanding human population. Though the public generally favors environmental protection, conservation does not come without sacrifice and cost. Many decision makers wonder if every species is worth the trouble. Of what consequence would the extinction of, say, spotted owls or snail darters be? Are some species expendable? Given the reality of limited money for conservation efforts, there is a compelling need for scientists to help conservation practitioners set priorities and identify species most in need of urgent attention. Ecology should be capable of providing guidance that goes beyond the obvious impulse to protect economically valuable species (salmon) or aesthetically appealing ones (snow leopards). Although some recent books have considered the ecosystem services provided by biodiversity as an aggregate property, this is the first to focus on the value of particular species. It provides the scientific approaches and analyses available for asking what we can expect from losing (or gaining) species. The contributors are outstanding ecologists, theoreticians, and evolutionary biologists who gathered for a symposium honoring Robert T. Paine, the community ecologist who experimentally demonstrated that a single predator species can act as a keystone species whose removal dramatically alters entire ecosystem communities. They build on Paine's work here by exploring whether we can identify species that play key roles in ecosystems before they are lost forever. These are some of our finest ecologists asking some of our hardest questions. They are, in addition to the editors, S.E.B. Abella, G. C. Chang, D. Doak, A. L. Downing, W. T. Edmondson, A. S. Flecker, M. J. Ford, C.D.G. Harley, E. G. Leigh Jr., S. Lubetkin, S. M. Louda, M. Marvier, P. McElhany, B. A. Menge, W. F. Morris, S. Naeem, S. R. Palumbi, A. G. Power, T. A. Rand, R. B. Root, M.

A new vision is sweeping through ecological science: The dense web of dependencies that makes up an ecosystem has gained an added dimension-the dimension of time. Every field, forest, and park is full of living organisms adapted for relationships with creatures that are now extinct. In a vivid narrative, Connie Barlow shows how the idea of "missing partners" in nature evolved from isolated, curious examples into an idea that is transforming how ecologists understand the entire flora and fauna of the Americas. This fascinating book will enrich the experience of any amateur naturalist, as well as teach us that the ripples of biodiversity loss around us are just the leading edge of what may well become perilous cascades of extinction.
Because carnivores are at the top of the food chain, it is often argued that protecting them will afford adequate protection to other taxa as well. In the past ten years, theoretical and empirical studies on carnivores have developed very quickly. This volume reviews and summarizes the current state of the field, describes limitations and opportunities for carnivore conservation, and offers a conceptual framework for future research and applied management. It will be of interest to students and researchers of conservation biology, mammalogy, animal behavior, ecology, and evolution.
Protecting Endangered Species in the United States is a collection of original papers by economists, biologists and political scientists with a common theme--protecting species at risk while safeguarding social order is a policy challenge that entangles biology, politics, and economics. The volume begins by assessing the biological needs that define the endangered species problem. The authors then explore the political realities that delimit the debate--who pays the costs and receives the benefits, and how interest groups affect species protection. The book addresses the economic choices that must be confronted for effective protection strategies including incentive schemes to promote preservation on public and private land.
An essential reference for anyone involved in protecting the
environment, this book identifies and describes Virginia's
endangered species and suggests ways that they might be managed to
ensure their survival. It incorporates the contributions of more
than eighty biologists.
Today's conservation literature emphasizes landscape ecology and population genetics without addressing the behavioral links that enable the long-term survival of populations. This book presents theoretical and practical arguments for considering behavior patterns in attempts to conserve biodiversity. It brings together prominent scientists and wildlife managers to address a number of issues, including the limits and potentials of behavioral research to conservation, the importance of behavioral variation as a component of biodiversity, and the use of animal behavior to solve conservation problems. Throughout, the text provides specific direction for research and management practices. The book is unique in its emphasis on conservation of wild populations as opposed to captive and reintroduced populations, where behavioral research has concentrated in the past.
Perhaps nothing about nature calls to us as deeply as wild animals. To see an enormous whale leaping out of the water, the eerily human eyes of a gorilla, or the comical waddle of a penguin; to hear the ethereal howl of a wolf or majestic roar of a lion-these experiences change us. Around the world, animal populations are threatened by loss of habitat, pollution, climate change, overhunting, and poaching-and yet wildlife-based tourism is growing rapidly and makes up as much as forty percent of the worldwide tourism industry today. In Pandas to Penguins, nature journalist Melissa Gaskill profiles twenty-five species and one endangered ecosystem, highlighting local ecofriendly travel outfitters operating in the area for those seeking out their own enriching personal experience with wildlife. She provides basic information about each animal's behavior and biology, descriptions of the threats they face, and maps, photographs, and first-person accounts of wildlife watching. Each species meets three basic criteria: 1) some level of risk to its survival, 2) a reasonably accessible habitat where travelers have a chance to view the animal in the wild in its natural setting, and 3) responsible tourism that directly benefits the animal or its habitat. More than a wildlife bucket list or an exhortation to "see them before they're gone," this guide is intended to identify wildlife experiences that can be life changing for people as well as animals. Extinction is tragic but not inevitable. We can all do something to make a difference, and Pandas to Penguins is an important resource for adventurers and armchair travelers alike.
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.
As the Condor Soars focuses on the increasing role that ornithologists played in public agencies, changing ideas about ecosystems, and conservation debates in Oregon. These themes are most clearly seen in the battles over the northern spotted owl and the development of the Northwest Forest Plan. Contributors to this volume also discuss new developments in the study of birds, such as sound studies, and connections between ornithologists and artists. The volume includes illustrations by Ram Papish.Â
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.

The Devils Hole pupfish is one of the rarest vertebrate animals on the planet; its only natural habitat is a ten-by-sixty-foot pool near Death Valley, on the Nevada-California border. Isolation in Devils Hole made the fish different from its close genetic relatives, but as Devils Hole Pupfish explores, what has made the species a survivor is its many surprising connections to the people who have studied, ignored, protested or protected it.
It is the evening of 26 August 2009 on Christmas Island. The last known pipistrelle emerges from its day-time shelter. Scientists, desperate about its conservation, set up a maze of netting to try to catch it. It is a forlorn and futile exercise - even if captured, there is little future in just one bat. But the bat evades the trap easily, and continues foraging. It is not recorded again that night, and not at all the next night. The bat is never again recorded. The scientists search all nearby areas over the following nights. It has gone. There are no more bats. Its corpse is not, will never be, found. It is the silent, unobtrusive death of the last individual. It is extinction. This book is about that bat, about those scientists, about that island. But mostly it is an attempt to understand that extinction; an unusual extinction, because it was predicted, witnessed and its timing is precise. A Bat's End is a compelling forensic examination of the circumstances and players surrounding the extinction of the Christmas Island pipistrelle. A must-read for environmental scientists, policy-makers, and organisations and individuals with an interest in conservation. FEATURES: Fascinating forensic examination of the processes and players involved in the extinction of the Christmas Island pipistrelle bat, including personal accounts of ecologists, administrators and politicians Considers our relationship with nature, and the extent to which we should and do care for nature Uses the Christmas Island pipistrelle bat's extinction as a case study, from which lessons can be learned that will resonate more broadly Examines Australia's environmental law and policy, and provides recommendations to strengthen these Foreword written by Tim Low, renowned Australian environmental consultant and author. "To bear witness to extinctions is painful, and made worse when hardly anyone knows they took place. By exploring one extinction from all angles, John gives Australians the opportunity to know what transpired on that island and to reflect on what it says about our nation's treatment of its wildlife. He tells a powerful and perceptive story, one that should be taken to heart by every Australian."" Tim Low, excerpt from the Foreword.
Australia's nature is exceptional, wonderful and important. But much has been lost, and the ongoingexistence of many species now hangs by a thread. Against a relentless tide of threats to our biodiversity,many Australians, and government and non-government agencies, have devoted themselves to thechallenge of conserving and recovering plant and animal species that now need our help to survive. Thisdedication has been rewarded with some outstanding and inspiring successes: of extinctions averted, ofpopulations increasing, of communities actively involved in recovery efforts. Recovering Australian Threatened Species showcases successful conservation stories and identifiesapproaches and implementation methods that have been most effective in recovering threatened species.These diverse accounts - dealing with threatened plants, invertebrates, fish, reptiles, birds and mammals- show that the conservation of threatened species is achievable: that it can be done and should be done.They collectively serve to inform, guide and inspire other conservation efforts. This is a book of hope andinspiration. It shows that with dedication, knowledge and support, we can retain and restore our marvellous natural heritage, and gift to our descendants a world that is as diverse, healthy and beautiful as that which we have inherited. FEATURES: Foreword written by Gregory Andrews, Australia's first Threatened Species Commissioner. Features inspiring Australian conservation success stories spanning a wide range of threatened species and habitats, demonstrating that recovery of threatened species is both achievable and worthwhile. Includes perspectives from expert conservation practitioners and draws lessons about what elements are important in achieving conservation successes.
An illustrated record of sea-eagles, harpy eagles, booted eagles and eagle-like hawks in Australasia. Eagles are awe-inspiring birds that have influenced much human endeavour. Australia is home to three eagle species, and in Melanesia there are four additional endemic species. A further three large Australian hawks are eagle-like. Eagles, being at the top of the food chain, are sensitive ecological barometers of human impact on the Earth’s ecosystem services, and all of the six Australian species covered in this book are threatened in at least some states (one also nationally). Three of the four Melanesian tropical forest endemics are threatened or near-threatened. In Australasian Eagles and Eagle-like Birds, Dr Stephen Debus provides a 25-year update of knowledge on these 10 species as a supplement to the Handbook of Australian, New Zealand and Antarctic Birds (HANZAB) and recent global treatises, based partly on his own field studies. Included are the first nest or prey records for some Melanesian species. This book places the Australasian species in their regional and global context, reviews their population status and threats, provides new information on their ecology, and suggests what needs to be done in order to ensure the future of these magnificent birds. Australasian Eagles and Eagle-like Birds is an invaluable resource for raptor biologists, birdwatchers, wildlife rescuers and carers, raptor rehabilitators and zookeepers. |
