Download or read book The Private Eye written by Mary Burns and published by UBC Press. This book was released on 1996 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Private Eye we learn about snow geese through the eyes of Native people, scientists, artists, hunters, and farmers. Yup'ik Eskimo Charles Hunt harvests snow geese along the Yukon River delta each fall, continuing a subsistence way of life that has existed for millennia. Russian, Canadian, and US scientists track the movements of the geese each spring and fall, banding, sexing, counting, and precisely monitoring the activities of these beautiful birds. Robert Bateman provides an artist's view of nature and relates how his curiosity led him to join a camp set up at a remote nesting site. Mary Burns also talks to hunters, joining a party of them as they wait for their snow geese decoys to lure the real thing into a Westham Island field in the Fraser delta. To complete the experience she prepares snow geese for supper. As well, Burns travels around the Skagit River delta during a population survey and meets a dairy farmer who describes both the wild flocks that converge on his fields each spring and the snow geese he raises in pens. The Private Eye suggests that by acknowledging our many and varied connections with the natural world, we will have a better understanding of the human place in it.

Download or read book Ducks Geese and Swans of North America written by Guy A. Baldassarre and published by JHU Press. This book was released on 2014 with total page 1183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ducks, Geese, and Swans of North America has been hailed as a classic since the first edition was published in 1942. A must-have for professional biologists, birders, waterfowl hunters, decoy collectors, and wildlife managers, this fully revised and updated edition provides definitive information on the continent's forty-six species. Maps of both winter and breeding ranges are presented with images by top waterfowl photographers and the acclaimed original artwork of Robert W. (Bob) Hines. Originally authored by F. H. Kortright and later revised by Frank Bellrose, this latest edition, which has been meticulously updated by renowned waterfowl biologist Guy Baldassarre, continues the legacy of esteemed authors. Each species account contains in-depth sections on: - identification - distribution - migration behavior - habitat - population status - breeding biology - rearing of young - recruitment and survival - food habits and feeding ecology - molts and plumages - conservation and management To facilitate identification, the species accounts also include detailed illustrations of wings. An appendix contains comparative illustrations of ducklings, goslings, and cygnets. Guy Baldassarre has hit the target. His remake of the Kortright/Bellrose classic provides good biological descriptions, wonderful photographs and illustrations, and easy-to-understand information about waterfowl. I would encourage every hunter and enthusiast to have these books as an educational guide to waterfowl and their needs.--H. Dale Hall, CEO, Ducks Unlimited, Inc. When, as an eleven-year-old in 1942, I read F. H. Kortright's first edition of this book, it altered the trajectory of my life. Every subsequent edition, including this latest update by Guy Baldassarre, has improved the landmark reference. I can't imagine that anyone interested in waterfowl or wetlands can live without this indispensable book.--Paul A. Johnsgard, University of Nebraska-Lincoln Creating a brand-new version of such a timeless and previously revised classic is a risky venture indeed, but nobody could be better suited for this monumental task than Guy Baldassarre. He has created a stunning new classic, at once magnificent in its visual appeal and truly comprehensive in its scientific breadth and depth. Hats off to Guy for dedicating himself to this project with such obvious passion, patience, and skill. This book absolutely belongs on the shelf or coffee table of anyone who has ever marveled at waterfowl, whether through their binoculars or from inside the duck blind.--John W. Fitzpatrick, Cornell Laboratory of Ornithology Guy Baldassarre was a professor of wildlife ecology at the State University of New York College of Environmental Science and Forestry in Syracuse until his death in 2012. He is the coauthor of the textbook, Waterfowl Ecology and Management.

Download or read book New Models for Ecosystem Dynamics and Restoration written by Richard J. Hobbs and published by Island Press. This book was released on 2013-03-19 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: As scientific understanding about ecological processes has grown, the idea that ecosystem dynamics are complex, nonlinear, and often unpredictable has gained prominence. Of particular importance is the idea that rather than following an inevitable progression toward an ultimate endpoint, some ecosystems may occur in a number of states depending on past and present ecological conditions. The emerging idea of “restoration thresholds” also enables scientists to recognize when ecological systems are likely to recover on their own and when active restoration efforts are needed. Conceptual models based on alternative stable states and restoration thresholds can help inform restoration efforts. New Models for Ecosystem Dynamics and Restoration brings together leading experts from around the world to explore how conceptual models of ecosystem dynamics can be applied to the recovery of degraded systems and how recent advances in our understanding of ecosystem and landscape dynamics can be translated into conceptual and practical frameworks for restoration. In the first part of the book, background chapters present and discuss the basic concepts and models and explore the implications of new scientific research on restoration practice. The second part considers the dynamics and restoration of different ecosystems, ranging from arid lands to grasslands, woodlands, and savannahs, to forests and wetlands, to production landscapes. A summary chapter by the editors discusses the implications of theory and practice of the ideas described in preceding chapters. New Models for Ecosystem Dynamics and Restoration aims to widen the scope and increase the application of threshold models by critiquing their application in a wide range of ecosystem types. It will also help scientists and restorationists correctly diagnose ecosystem damage, identify restoration thresholds, and develop corrective methodologies that can overcome such thresholds.

Book excerpt: "The primary purpose of this compendium is to give detailed results of a Snow-Blue Goose (Chen caerulescens) band recovery analysis and provide supporting data to conclusions presented in a previous report, (Dzubin, Boyd and Stephen, 1973). Secondarily, it attempts to draw together population data which will aid managers, administrators and researchers to plan future programs or management strategies. The recovery data themselves are presented in a standardized format and are referenced in nine appendices, to aid resource managers in assessing the available distribution evidence"--Introduction, page 1.

Download or read book The Snow Geese written by William Fiennes and published by Vintage Canada. This book was released on 2010-07-07 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a debut of great delicacy and distinction, a young nature philosopher describes his journey as he follows the northern migration of the snow goose and reflects on the powerful attraction of home. Every spring, millions of geese embark on an arduous three-thousand-mile homeward journey from their winter quarters in the southern United States to their breeding grounds in the Canadian Arctic. One year William Fiennes, recovering from a long illness, decided to go with them. Intrigued by what he’d read about the birds’ extraordinary annual journey, he was also desperate to escape the depression that had dogged his convalescence, and the belief that at age twenty-six, his life had ground to a halt. Part memoir, part nature study, part travelogue, the story of Fiennes’s journey is not just about geese. It’s about homecoming: the birds on their long trip home, the pull of nostalgia, the urge to leave home and the even stronger urge to return. Fiennes is a gifted natural writer with a distinctive voice that is deeply thoughtful, wry and keenly observant. His book vibrates with ideas, with stories and anecdotes, with humankind as well as wild fowl. The joy of being alive, being on the move and – above all – going home are poignantly captured in this intelligent, exuberant book.

Download or read book The Ecology of Browsing and Grazing II written by Iain J. Gordon and published by Springer Nature. This book was released on 2019-11-12 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Domestic and wild large mammalian herbivores occur on every continent except Antarctica. Through their browsing and grazing, they affect the structure and distribution not only of vegetation, but also of associated fauna. Consequently, the interactions between management practices and herbivore populations influence the biodiversity, structure and dynamics of ecosystems across vast expanses around the globe: signs of human activity that will be detectable for epochs to come. As a follow-up work to The Ecology of Browsing and Grazing, published in 2008, this new volume presents cutting-edge research on the behaviour, distribution, movement, and direct and indirect impacts of domestic and wild herbivores on terrestrial ecosystems. The respective chapters highlight strategic and applied research on cross-cutting issues in palaeontology and ecology, and provide concrete recommendations on the management of large herbivores to integrate production and conservation in terrestrial systems. Given its scope, the book will appeal to students, researchers and anyone interested in understanding these fascinating wild animals and how they shape the natural world.

Download or read book Ecology of Arctic Environments written by Sarah J. Woodin and published by Cambridge University Press. This book was released on 1997-08 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once thought of as a pristine environment, it is now all too apparent that the Arctic is a sink for pollutants transported northwards over long distances in the atmosphere and oceans, and is also likely to be subject to major climate change as a result of global warming. Many ecologists are currently seeking to further our understanding of how arctic ecosystems function, and to detect and predict anthropogenic changes which may occur within them. This book, resulting from a British Ecological Society Special Symposium, addresses these issues.

Download or read book Avian Genetics written by F. Cooke and published by Academic Press. This book was released on 2013-09-24 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avian Genetics: A Population and Ecological Approach is a collection of papers that deals with the study of birds in relation to the synthetic theory of evolution. This book studies the ecology, demography, behavior, and geographical distribution of birds; the text also discusses quantitative, chromosomal, biochemical, and population genetics. Part I reviews the various genetic interactions, including an analysis of DNA sequence variation. The different and newer techniques are compared such as the works of Sibley, Quinn, and White. Part II describes the molding genetic variation and covers topics such as inbreeding; gene flow and the genetic structure of populations; non-random mating; and the process of selection in natural populations of birds. Part III covers actual genetic case histories, including quantitative ecological genetics of great tits; genetic evolution of house sparrows; and presentation of evidence for sexual selection by female choice in the Arctic Skua. This book also presents future research in subjects such as the neutrality-selection controversy or genetics and conservation. This text can be beneficial for ecologists, ornithologists, animal conservationists, and population biologists studying birds.
