Download or read book Wolves Bears and Their Prey in Alaska written by National Research Council and published by National Academies Press. This book was released on 1997-11-27 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book assesses Alaskan wolf and bear management programs from scientific and economic perspectives. Relevant factors that should be taken into account when evaluating the utility of such programs are identified. The assessment includes a review of current scientific knowledge about the dynamics and management of large mammalian predator-prey relationships and human harvest of wildlife in northern ecosystems, and an evaluation of the extent to which existing research and management data allow prediction of the outcome of wolf management or control programs and grizzly bear management programs. Included is an evaluation of available economic studies and methodologies for estimating the costs and benefits of predator control programs in Alaska.
Download or read book Predation written by R. J. Taylor and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: When assuming the task of preparing a book such as this, one inevitably wonders why anyone would want to read it. I have always sympathized with Charles Elton's trenchant observation in his 1927 book that 'we have to face the fact that while ecological work is fascinating to do, it is unbearably dull to read about . . . ' And yet several good reasons do exist for producing a small volume on predation. The subject is interesting in its own right; no ecologist can deny that predation is one of the basic processes in the natural world. And the logical roots for much currently published reasoning about predation are remarkably well hidden; if one must do research on the subject, it helps not to be forced to start from first principles. A student facing predator-prey interactions for the first time is confronted with an amazingly diverse and sometimes inaccessible literature, with a ratio of wheat to chaff not exceeding 1: 5. A guide to the perplexed in this field does not exist at present, and I hope the book will serve that function. But apart from these more-or-Iess academic reasons for writing the book, I am forced to it by my conviction that predators are important in the ecological scheme. They playa critical role in the biological control of insects and other pests and are therefore of immediate economic concern.
Download or read book Among Wolves written by Marybeth Holleman and published by University of Alaska Press. This book was released on 2013-10-15 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alaska’s wolves lost their fiercest advocate, Gordon Haber, when his research plane crashed in Denali National Park in 2009. Passionate, tenacious, and occasionally brash, Haber, a former hockey player and park ranger, devoted his life to Denali’s wolves. He weathered brutal temperatures in the wild to document the wolves and provided exceptional insights into wolf behavior. Haber’s writings and photographs reveal an astonishing degree of cooperation between wolf family members as they hunt, raise pups, and play, social behaviors and traditions previously unknown. With the wolves at risk of being destroyed by hunting and trapping, his studies advocated for a balanced approach to wolf management. His fieldwork registered as one of the longest studies in wildlife science and had a lasting impact on wolf policies. Haber’s field notes, his extensive journals, and stories from friends all come together in Among Wolves to reveal much about both the wolves he studied and the researcher himself. Wolves continue to fascinate and polarize people, and Haber’s work continues to resonate.
