Download or read book Yellowstone Wolves written by Douglas W. Smith and published by University of Chicago Press. This book was released on 2020-12-28 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This beautifully illustrated volume on the Yellowstone Wolf Project includes an introduction by Jane Goodall and an exclusive online documentary. The reintroduction of wolves to Yellowstone National Park was one of the greatest wildlife conservation achievements of the twentieth century. Eradicated after the park was first established, these iconic carnivores returned in 1995 when the US government reversed its century-old policy of extermination. In the intervening decades, scientists have built a one-of-a-kind field study of these wolves, their behaviors, and their influence on the entire ecosystem. Yellowstone Wolves tells the incredible story of the Yellowstone Wolf Project, as told by the people behind it. This wide-ranging volume highlights what has been learned in the decades since reintroduction, as well as the unique blend of research techniques used to gain this knowledge. We learn about individual wolves, population dynamics, wolf-prey relationships, genetics, disease, management and policy, and the rippling ecosystem effects wolves have had on Yellowstone’s wild and rare landscape. Featuring a foreword by Jane Goodall, beautiful images, a companion online documentary by celebrated filmmaker Bob Landis, and contributions from more than seventy wolf and wildlife conservation luminaries from Yellowstone and around the world, Yellowstone Wolves is an informative and beautifully realized celebration of the extraordinary Yellowstone Wolf Project.
Download or read book Summer Wolf Diet in Northwestern Montana written by Jonathan Derbridge and published by . This book was released on 2010 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wolf (Canis lupus) diet can be estimated from undigested remains of prey in scats or through stable isotope analysis (SIA) of wolf hair when distinct Iþ13C and Iþ15N values of potential diet sources are known. Our objectives were to compare diet analysis methods, to estimate intra-population diet variability, and to determine proportions of prey consumed by wolves. We collected scats of 4 wolf packs in northwestern Montana from June to August 2008, and guard hairs of 45 wolves from 12 packs, May to August 2009. We calculated percent biomass consumed of deer (Odocoileus spp.), elk (Cervus canadensis), moose (Alces alces), and other items from scats, and used Pearson's chi-squared tests of proportions to measure differences among packs. We used hierarchical Bayesian stable isotope mixing models to determine diet and scales of diet variation from Iþ13C and Iþ15N values of wolves and prey. We used bootstrapped scat data, and Markov Chain Monte Carlo simulation data from stable isotopes to estimate confidence intervals of difference between results from each technique for 4 packs with matched samples. Diet results were not consistent between techniques. Deer was the most common prey item based on scats, and moose the most common based on SIA. Wolf diet was significantly different among packs based on scats, and differences among packs explained most variability in diet based on stable isotopes. We sampled 3 times as many packs for less than half the cost with SIA compared to scat analysis. Experimental data on wolf hair growth period and wolf-specific Iþ13C and Iþ15N fractionation values would provide important information for recommending the better technique.

Download or read book Predation in Vertebrate Communities written by Bogumila Jedrzejewska and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predation, one of the most dramatic interactions in animals' lives, has long fascinated ecologists. This volume presents carnivores, raptors and their prey in the complicated net of interrelationships, and shows them against the background of their biotic and abiotic settings. It is based on long-term research conducted in the best preserved woodland of Europe's temperate zone. The role of predation, whether limiting or regulating prey (ungulate, rodent, shrew, bird, and amphibian) populations, is quantified and compared to parts played by other factors: climate, food resources for prey, and availability of other potential resources for predators.

Download or read book The Yellowstone Wolf written by Paul Schullery and published by University of Oklahoma Press. This book was released on 2003 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: All royalties from sales of this book go to Yellowstone’s wolf recovery project Few animals inspire such a mixture of fear, curiosity, and wonder as the wolf. Highly regarded but often misunderstood, the wolf has as many friends as enemies, and its reintroduction into Yellowstone National Park has sparked both fascination and controversy. Early in Yellowstone’s history, wolves were thought supernaturally evil, and scores were destroyed. Northern Rocky Mountain wolves were native to Yellowstone when the park was established in 1872, but “predator control” led to determined eradication, and by the 1940s they were gone. Amid much fanfare, however, wolves were reintroduced to one of the nation’s oldest national parks in the 1990s. This comprehensive reference documents the prehistory, management, and nature of the Yellowstone wolf. Historian-naturalist Paul Schullery has assembled the voices of explorers, naturalists, park officials, tourists, lawmakers, and modern researchers to tell the story of what may be the most famous wolf population in the world. This unique book includes numerous scientific studies of interest to wolf enthusiasts and scholars of western wildlife issues, conservation, and national parks. In a new afterword, Schullery discusses recent developments in the recovery project.

Available in PDF, EPUB and Kindle. Book excerpt: Learn to communicate with your dog—using their language “Good reading for dog lovers and an immensely useful manual for dog owners.”—The Washington Post An Applied Animal Behaviorist and dog trainer with more than twenty years’ experience, Dr. Patricia McConnell reveals a revolutionary new perspective on our relationship with dogs—sharing insights on how “man’s best friend” might interpret our behavior, as well as essential advice on how to interact with our four-legged friends in ways that bring out the best in them. After all, humans and dogs are two entirely different species, each shaped by its individual evolutionary heritage. Quite simply, humans are primates and dogs are canids (as are wolves, coyotes, and foxes). Since we each speak a different native tongue, a lot gets lost in the translation. This marvelous guide demonstrates how even the slightest changes in our voices and in the ways we stand can help dogs understand what we want. Inside you will discover: • How you can get your dog to come when called by acting less like a primate and more like a dog • Why the advice to “get dominance” over your dog can cause problems • Why “rough and tumble primate play” can lead to trouble—and how to play with your dog in ways that are fun and keep him out of mischief • How dogs and humans share personality types—and why most dogs want to live with benevolent leaders rather than “alpha wanna-bes!” Fascinating, insightful, and compelling, The Other End of the Leash is a book that strives to help you connect with your dog in a completely new way—so as to enrich that most rewarding of relationships.
