Extinction has occurred throughout the history of life, and nearly all the species that have ever existed have now disappeared. In this 'Very Short Introduction', Paul B. Wignall looks at the causes and nature of extinction events, what makes a species vulnerable, and the debates in modern science of the role of climate and humans.
Most people are familiar with the dodo and the dinosaur, but extinction has occurred throughout the history of life, with the result that nearly all the species that have ever existed are now extinct. Today, species are disappearing at an ever increasing rate, whilst past losses have occurred during several great crises. Issues such as habitat destruction, conservation, climate change, and, during major crises, volacanism and meteorite impact, can all contribute towards the demise of a group. In this Very Short Introduction, Paul B. Wignall looks at the causes and nature of extinctions, past and present, and the factors that can make a species vulnerable. Summarising what we know about all of the major and minor exctinction events, he examines some of the greatest debates in modern science, such as the relative role of climate and humans in the death of the Pleistocene megafauna, including mammoths and giant ground sloths, and the roles that global warming, ocean acidification, and deforestation are playing in present-day extinctions ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

The proposal that the impact of humanity on the planet has left a distinct footprint, even on the scale of geological time, has recently gained much ground. Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species - these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The Anthropocene, as the proposed new epoch has been named, is regularly in the news. Even with such robust evidence, the proposal to formally recognize our current time as the Anthropocene remains controversial both inside and outside the scholarly world, kindling intense debates. The reason is clear. The Anthropocene represents far more than just another interval of geologic time. Instead, the Anthropocene has emerged as a powerful new narrative, a concept through which age-old questions about the meaning of nature and even the nature of humanity are being revisited and radically revised. This Very Short Introduction explains the science behind the Anthropocene and the many proposals about when to mark its beginning: the nuclear tests of the 1950s? The beginnings of agriculture? The origins of humans as a species? Erle Ellis considers the many ways that the Anthropocene's "evolving paradigm" is reshaping the sciences, stimulating the humanities, and foregrounding the politics of life on a planet transformed by humans. The Anthropocene remains a work in progress. Is this the story of an unprecedented planetary disaster? Or of newfound wisdom and redemption? Ellis offers an insightful discussion of our role in shaping the planet, and how this will influence our future on many fronts.

This text is about the central role of evolution in shaping the nature and diversity of the living world. It describes the processes of natural selection, how adaptations arise, and how new species form, as well as summarizing the evidence for evolution
Climate change is still, arguably, the most critical and controversial issue facing the world in the twenty-first century. Previously published as Global Warming: A Very Short Introduction, the new edition is now Climate Change: A Very Short introduction, reflecting an important change in the terminology of the last decade. In the third edition, Mark Maslin includes crucial updates from the last few years, including the results of the 2013 IPCC Fifth Assessment Report, the effects of ocean acidification, and the impact of changes to global population and health. Exploring all of the key topics in the debate, Maslin makes sense of the complexities climate change involves, from political and social issues to environmental and scientific. Looking at its predicated impacts, he explores all of the controversies, and also explains the various proposed solutions.

Caught on camera prior to their demise, this book reveals the surprisingly rich photographic record of now-extinct animals. A photograph of an animal long-gone evokes a feeling of loss more than a painting ever can. Often tinted sepia or black-and-white, these images were mainly taken in zoos or wildlife parks, and in a handful of cases featured the last known individual of the species. There are some familiar examples, such as Martha, the last Passenger Pigeon, or the Ivory-billed Woodpecker, recently fledged and perching happily on the hat of one of the biologists that had just ringed it. But for every Martha there are a number of less familiar extinct birds and mammals that were caught on camera. The photographic record of extinction is the focus of this remarkable book, written by the world's leading authority on vanished animals, Errol Fuller. Lost Animals features photographs dating from around 1870 to as recently as 2004, the year that saw the demise of the Hawaiian Po'ouli. From a mother Thylacine and her pups to now-extinct birds such as the Heath Hen and Carolina Parakeet, Fuller tells the tale of each animal, why it became extinct, and discusses the circumstances surrounding the photography itself, in a book rich with unique images. The photographs themselves are poignant and compelling. They provide a tangible link to animals that have now vanished forever, in a book that brings the past to life while delivering a warning for the future.
Some 250 million years ago, the earth suffered the greatest biological crisis in its history. Around 95 percent of all living species died out—a global catastrophe far greater than the dinosaurs' demise 185 million years later. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on the subject provides a fascinating overview of the evidence for and against a whole host of hypotheses concerning this cataclysmic event that unfolded at the end of the Permian. After setting the scene, Erwin introduces the suite of possible perpetrators and the types of evidence paleontologists seek. He then unveils the actual evidence--moving from China, where much of the best evidence is found; to a look at extinction in the oceans; to the extraordinary fossil animals of the Karoo Desert of South Africa. Erwin reviews the evidence for each of the hypotheses before presenting his own view of what happened. Although full recovery took tens of millions of years, this most massive of mass extinctions was a powerful creative force, setting the stage for the development of the world as we know it today. In a new preface, Douglas Erwin assesses developments in the field since the book's initial publication.
The research paper "Extinction Risk from Climate Change" published in the journal Nature in January 2004 created front-page headlines around the world. The notion that climate change could drive more than a million species to extinction captured both the popular imagination and the attention of policy-makers, and provoked an unprecedented round of scientific critique. Saving a Million Species reconsiders the central question of that paper: How many species may perish as a result of climate change and associated threats? Leaders from a range of disciplines synthesize the literature, refine the original estimates, and elaborate the conservation and policy implications. The book: examines the initial extinction risk estimates of the original paper, subsequent critiques, and the media and policy impact of this unique study presents evidence of extinctions from climate change from different time frames in the past explores extinctions documented in the contemporary record sets forth new risk estimates for future climate change considers the conservation and policy implications of the estimates. Saving a Million Species offers a clear explanation of the science behind the headline-grabbing estimates for conservationists, researchers, teachers, students, and policy-makers. It is a critical resource for helping those working to conserve biodiversity take on the rapidly advancing and evolving global stressor of climate change-the most important issue in conservation biology today, and the one for which we are least prepared.
This is a wide-ranging study of current and likely future species extinction rates, aimed at students and researchers in the environmental sciences. It highlights apparent differences in extinction rates among taxonomic groups and places, aiming to identify unresolved issues.
The present book combines three main aspects: five major mass extinctions; contributions on some other minor extinctions; and more importantly contributions on the current mass extinction. All three aspects are introduced through interesting studies of mass extinctions in diverse organisms ranging from small invertebrates to mammals and take account of the most accepted subjects discussing mass extinctions in insects, mammals, fishes, ostracods and molluscs.
