Available in PDF, EPUB and Kindle. Book excerpt: An extinction vortex is one of the greatest threats to endangered species; when demographic, environmental, and genetic stochasticity interact with each other and with deterministic factors, such as habitat quality, to reinforce the demise of a small population. To successfully escape an extinction vortex and enable species recovery, all processes that affect endangered populations should be comprehensively assessed and incorporated into conservation plans. For my dissertation, I worked in conjunction with California Department of Fish and Game to develop a comprehensive research program to guide recovery efforts for federally endangered Sierra Nevada bighorn sheep, the rarest subspecies of mountain sheep in North America. I initiated a combination of demographic, habitat and genetic analyses to identify the stochastic and deterministic factors limiting the recovery of this subspecies, examine the relative and synergistic impacts of these factors on the performance of Sierra Nevada bighorn sheep, and the benefits of different management activities for stimulating recovery efforts. Just as the extinction vortex predicts, I found that small populations of Sierra Nevada bighorn sheep were driven by a number of stochastic and deterministic processes. Demographic, habitat, climate, predation, and genetic factors operated singly and in concert to shape the overall viability of this subspecies. The interaction of factors led to atypical demographic patterns that deviated from theoretical expectations and increased extinction risk. To alleviate extinction processes, I found that management strategies must be tailored to population-specific dynamics, targeting those vital rates and ecological drivers which have the greatest power to increase performance. Results from this study have elucidated critical aspects of Sierra Nevada bighorn sheep ecology, provided a recovery strategy for this subspecies, and supplied new quantitative tools for examining the dynamics of small and endangered populations. Ultimately, this work offers an example of assessing population viability, not in terms of probability of extinction, but in terms of quantifying conservation measures that will alleviate extinction dynamics and achieve endangered species recovery goals.

Book Synopsis The Paradise Notebooks by : Richard J. Nevle
Download or read book The Paradise Notebooks written by Richard J. Nevle and published by Cornell University Press. This book was released on 2022-04-15 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Paradise Notebooks, Richard J. Nevle and Steven Nightingale take us across the spectacular Sierra Nevada mountain range on a journey illuminated by incandescent poetry and fascinating fact. Over the course of twenty-one pairs of short essays, Nevle and Nightingale contemplate the natural phenomena found in the Sierra Nevada. From granite to aspen, to fire, to a rare, endemic species of butterfly, these essay pairs explore the natural history and mystical wonder of each element with a balanced and captivating touch. As they weave in vignettes from their ninety-mile backpacking trip across the range, Nevle and Nightingale powerfully reconceive the Sierra Nevada as both earthly matter and transcendental offering, letting us into a reality in which nature holds just as much spiritual importance as it does physical. In a time of rapid environmental degradation, The Paradise Notebooks offers a way forward—a whole-minded, learned, loving attention to place that rekindles our joyful relationship with the living world.
Book Synopsis Paleogenomics by : Charlotte Lindqvist
Download or read book Paleogenomics written by Charlotte Lindqvist and published by Springer. This book was released on 2019-01-07 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in genome-scale DNA sequencing technologies have revolutionized genetic research on ancient organisms, extinct species, and past environments. When it is recoverable after hundreds or thousands of years of unintended preservation, “ancient DNA” (or aDNA) is often highly degraded, necessitating specialized handling and analytical approaches. Paleogenomics defines the field of reconstructing and analyzing the genomes of historic or long-dead organisms, most often through comparison with modern representatives of the same or similar species. The opportunity to isolate and study paleogenomes has radically transformed many fields, spanning biology, anthropology, agriculture, and medicine. Examples include understanding evolutionary relationships of extinct species known only from fossils, the domestication of plants and animals, and the evolution and geographical spread of certain pathogens. This pioneering book presents a snapshot view of the history, current status, and future prospects of paleogenomics, taking a broad viewpoint that covers a range of topics and organisms to provide an up-to-date status of the applications, challenges, and promise of the field. This book is intended for a variety of readerships, including upper-level undergraduate and graduate students, professionals and experts in the field, as well as anyone excited by the extraordinary insights that paleogenomics offers.

Download or read book The Missing Lynx written by Ross Barnett and published by Bloomsbury Publishing. This book was released on 2019-07-11 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Britain's lynx are missing, and they have been for more than a thousand years. Why have they gone? And might they come back? 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.
Book Synopsis The Tragedy of the Commodity by : Stefano B. Longo
Download or read book The Tragedy of the Commodity written by Stefano B. Longo and published by Rutgers University Press. This book was released on 2015-06-25 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2017 Paul Sweezy Marxist Sociology Book Award from the American Sociological Association Although humans have long depended on oceans and aquatic ecosystems for sustenance and trade, only recently has human influence on these resources dramatically increased, transforming and undermining oceanic environments throughout the world. Marine ecosystems are in a crisis that is global in scope, rapid in pace, and colossal in scale. In The Tragedy of the Commodity, sociologists Stefano B. Longo, Rebecca Clausen, and Brett Clark explore the role human influence plays in this crisis, highlighting the social and economic forces that are at the heart of this looming ecological problem. In a critique of the classic theory “the tragedy of the commons” by ecologist Garrett Hardin, the authors move beyond simplistic explanations—such as unrestrained self-interest or population growth—to argue that it is the commodification of aquatic resources that leads to the depletion of fisheries and the development of environmentally suspect means of aquaculture. To illustrate this argument, the book features two fascinating case studies—the thousand-year history of the bluefin tuna fishery in the Mediterranean and the massive Pacific salmon fishery. Longo, Clausen, and Clark describe how new fishing technologies, transformations in ships and storage capacities, and the expansion of seafood markets combined to alter radically and permanently these crucial ecosystems. In doing so, the authors underscore how the particular organization of social production contributes to ecological degradation and an increase in the pressures placed upon the ocean. The authors highlight the historical, political, economic, and cultural forces that shape how we interact with the larger biophysical world. A path-breaking analysis of overfishing, The Tragedy of the Commodity yields insight into issues such as deforestation, biodiversity loss, pollution, and climate change.

Download or read book Ecology written by Michael Begon and published by John Wiley & Sons. This book was released on 2020-11-11 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: A definitive guide to the depth and breadth of the ecological sciences, revised and updated The revised and updated fifth edition of Ecology: From Individuals to Ecosystems – now in full colour – offers students and practitioners a review of the ecological sciences. The previous editions of this book earned the authors the prestigious ‘Exceptional Life-time Achievement Award’ of the British Ecological Society – the aim for the fifth edition is not only to maintain standards but indeed to enhance its coverage of Ecology. In the first edition, 34 years ago, it seemed acceptable for ecologists to hold a comfortable, objective, not to say aloof position, from which the ecological communities around us were simply material for which we sought a scientific understanding. Now, we must accept the immediacy of the many environmental problems that threaten us and the responsibility of ecologists to play their full part in addressing these problems. This fifth edition addresses this challenge, with several chapters devoted entirely to applied topics, and examples of how ecological principles have been applied to problems facing us highlighted throughout the remaining nineteen chapters. Nonetheless, the authors remain wedded to the belief that environmental action can only ever be as sound as the ecological principles on which it is based. Hence, while trying harder than ever to help improve preparedness for addressing the environmental problems of the years ahead, the book remains, in its essence, an exposition of the science of ecology. This new edition incorporates the results from more than a thousand recent studies into a fully up-to-date text. Written for students of ecology, researchers and practitioners, the fifth edition of Ecology: From Individuals to Ecosystems is anessential reference to all aspects of ecology and addresses environmental problems of the future.
