Download or read book The Biology and Conservation of Wild Canids written by David W. Macdonald and published by OUP Oxford. This book was released on 2004-06-24 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: No group of wild mammals so universally captures the emotions of people world-wide than do wild canids. That emotion can be enchantment and fascination, but it can also be loathing, because the opportunism that is the hallmark of the dog family also leads them into conflict with humans. In the developed world at least, the fascination with wild canids doubtless stems from people's captivation with domestic dogs - everybody feels they are an expert on canids! While most people may be familiar with only the better known members of the dog family, such as the grey wolf and the red fox, there are in fact 36 species of wolves, dogs, jackals and foxes. They attract hugely disproportionate interest from academics, conservationists, veterinarians, wildlife managers and the general public. This book brings together in single volume an astonishing synthesis of research done in the last twenty years and is the first truly compendious synthesis on wild canids. Beginning with a complete account of all 36 canid species, there follow six review chapters that emphasise topics most relevant to canid conservation science, including evolution and systematics, behavioural ecology, population genetics, diseases, conflict/control of troublesome species, and conservation tools. Fifteen detailed case studies then delve deeply into the very best species investigations currently available written by all the leading figures in the field. Much of the material is previously unpublished and will make fascinating reading far beyond the confines of canid specialists. These chapters portray the unique attributes of wild canids, their fascinating (and conflictive) relationship with man, and suggestions for future research and conservation measures for the Canidae. While most canid species are widespread and thrive in human dominated landscapes, several are in severe jeopardy; habitat loss, illegal hunting, persecution by farmers and disease all imperil dwindling populations. A final chapter analyses the requirements of, and approaches to, practical conservation, with lessons that go far beyond the dog family. It concentrates particular attention on priorities for the protection of the most threatened canid species, including the red wolf, African wild dog, Ethiopian wolf, Island fox and Darwin's fox. The wild canids provide examples that will thrill the evolutionary biologists and theoretician, enthral the natural historian and challenge the conservationist and wildlife manager. Anybody interested in evolutionary and behavioural biology, in mammals, in the environment, or in conservation will find much that is new and enriching in this book.

Download or read book Genetic Management of Fragmented Animal and Plant Populations written by Richard Frankham and published by Oxford University Press. This book was released on 2017 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Population Dynamics in Variable Environments written by Shripad Tuljapurkar and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Demography relates observable facts about individuals to the dynamics of populations. If the dynamics are linear and do not change over time, the classical theory of Lotka (1907) and Leslie (1945) is the central tool of demography. This book addresses the situation when the assumption of constancy is dropped. In many practical situations, a population will display unpredictable variation over time in its vital rates, which must then be described in statistical terms. Most of this book is concerned with the theory of populations which are subject to random temporal changes in their vital rates, although other kinds of variation (e. g. , cyclical) are also dealt with. The central questions are: how does temporal variation work its way into a population's future, and how does it affect our interpretation of a population's past. The results here are directed at demographers of humans and at popula tion biologists. The uneven mathematical level is dictated by the material, but the book should be accessible to readers interested in population the ory. (Readers looking for background or prerequisites will find much of it in Hal Caswell's Matrix population models: construction, analysis, and in terpretation (Sinauer 1989) ). This book is in essence a progress report and is deliberately brief; I hope that it is not mystifying. I have not attempted to be complete about either the history or the subject, although most sig nificant results and methods are presented.

Available in PDF, EPUB and Kindle. Book excerpt: How the fur trade changed the North and created the modern Arctic: “The history is fascinating.” —Anchorage Daily News In the early twentieth century, northerners lived and trapped in one of the world’s harshest environments. At a time when government services and social support were minimal or nonexistent, they thrived on the fox fur trade, relying on their energy, training, discipline, and skills. John R. Bockstoce, a leading scholar of the Arctic fur trade who also served as a member of an Eskimo whaling crew, explores the twentieth-century history of the Western Arctic fur trade to the outbreak of World War II, covering an immense region from Chukotka, Russia, to Arctic Alaska and the Western Canadian Arctic. This period brought profound changes to Native peoples of the North. To show its enormous impact, the author draws on interviews with trappers and traders, oral and written archival accounts, research in newspapers and periodicals, and his own field notes from 1969 to the present. A Choice Outstanding Academic Title of the Year Honorary Mention, 2020 William Mills Prize for Non-fiction Polar Books “An engaging story that is chock-full of fascinating anecdotes.” —Arctic “Invaluable . . . future generations of historians will refer to it.” —Canadian Journal of History “A compelling narrative . . .

Download or read book Jan Mayen Island in Scientific Focus written by Stig Skreslet and published by Springer Science & Business Media. This book was released on 2013-11-13 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jan Mayen is a volcanic island surrounded by the deep Greenland, Iceland and Norwegian Seas. There, atmospheric and oceanic processes unleash potential energy that forces very dynamic interactions between sea and air. This unique geophysical focal point generates climatic variability in northern Europe, and supports marine biological production that sustains the yield of large living resources. The marine populations are clearly fluctuating with variations in climate, and raises questions about effects of man-made climate change. Since the last Ice Age the sinking of Greenland Sea Deep-Water has been a substantial driving force for the Global Thermo-Haline Circulation which feeds warm Atlantic water into the Nordic Seas. Global warming may interact with the deep-water formation and force feedback mechanisms that express themselves beyond imagination. The book addresses such problems to raise an interest for doing research on the island and in its waters. The potentials for doing that increases when the island's Loran-C station closes down in 2005. The book recommends how the international scientific community may gain access to this really challenging arena for local, regional and Global research. It is a blueprint for the logistics required for science to succeed in a very remote and physically demanding place on Earth.

Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of cyclic population fluctuation in small rodents, and specifically lemmings, has been a major issue in ecology for decades. A number of questions, both truly scientific and also of popular mythology,surround the biology of these animals. Although a tremendous amount of research has been carried out on lemmings, much remains to be resolved. And while the story of the suicidal rodent is now understood as myth, the facts behind the population behavior of lemmings require further study. In this book well-known ecologists Stenseth and Ims have brought together a number of leading experts from both North America and Europe to review our current understanding of the taxonomy, population biology, feeding, and community ecology of lemmings.The authors put this current, but rather fragmentary, understanding of lemming biology into a general population biological context."In many ways we see lemmings as an important model species within population biology,"Stenseth acknowledges in the preface. Starting with the 16th Century, the book's introduction overviews the history of lemming research. The chapters are grouped into theme sections, each prefaced by an introductory review by the editors. The overall result is the most comprehensive and coherent overview of the subject to date.Finally, six appendices give detailed advice on how to study lemmings, which will provide an invaluable reference for research in the future. Contains never-before published material on the Norwegian lemming Lemmus lemmus Includes papers presented at a meeting on lemming biology at the biological station of Konnevesi at the University of Jyvaskyla, Finland Edited and authored by experts in the field

Available in PDF, EPUB and Kindle. Book excerpt: I guess I always felt even if the world came to an end, McDonald's still would be open. High school sophomore Miranda's disbelief turns to fear in a split second when an asteroid knocks the moon closer to Earth, like "one marble hits another." The result is catastrophic. How can her family prepare for the future when worldwide tsunamis are wiping out the coasts, earthquakes are rocking the continents, and volcanic ash is blocking out the sun? As August turns dark and wintery in northeastern Pennsylvania, Miranda, her two brothers, and their mother retreat to the unexpected safe haven of their sunroom, where they subsist on stockpiled food and limited water in the warmth of a wood-burning stove. Told in a year's worth of journal entries, this heart-pounding story chronicles Miranda's struggle to hold on to the most important resource of all--hope--in an increasingly desperate and unfamiliar world. An extraordinary series debut Susan Beth Pfeffer has written several companion novels to Life As We Knew It, including The Dead and the Gone, This World We Live In, and The Shade of the Moon.
