Download or read book The Timber Wolf in Wisconsin written by Richard P. Thiel and published by Univ of Wisconsin Press. This book was released on 1993 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: In early 1958, in the far northern town of Cornucopia, Wisconsin's "last" timber wolf was accidentally run over by an automobile. The "humane" intention to end the animal's suffering produced a grisly aftermath: the wolf survived the impact of the car, was bludgeoned with a tire iron twice but survived, and finally had its throat slit with a restaurant knife. This horrifying scene is certainly an apt (if appalling) symbol of the timber wolf's early fate in Wisconsin. Feared, detested, hunted down for state-authorized bounties, the animal was systematically exterminated as an enemy of man and progress. Yet this bleak chapter in the history of conservation has a happier ending. Seventeen years later, in 1975, the timber wolf had officially reestablished itself and, as a protected species, is now flourishing under the care of Wisconsin's Department of Natural Resources. Few can be more caring than the author, a DNR educator in wildlife management. As an inquisitive teenager, Richard Thiel began his pursuit of the Wisconsin timber wolf's story in the mid-1960s and has been at it ever since. The result is this arresting, intensely readable book, a story of fear, mistrust, and misunderstanding that ends, thankfully, as one of hope and appreciation.

Download or read book The Beaver written by Dietland Müller-Schwarze and published by Cornell University Press. This book was released on 2003 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beavers can and do dramatically change the landscape. The beaver is a keystone species their skills as foresters and engineers create and maintain ponds and wetlands that increase biodiversity, purify water, and prevent large-scale flooding. Biologists have long studied their daily and seasonal routines, family structures, and dispersal patterns. As human development encroaches into formerly wild areas, property owners and government authorities need new, nonlethal strategies for dealing with so-called nuisance beavers. At the same time, the complex behavior of beavers intrigues visitors at parks and other wildlife viewing sites because it is relatively easy to observe.In an up-to-date, exhaustively illustrated, and comprehensive book on beaver biology and management, Dietland Muller-Schwarze and Lixing Sun gather a wealth of scientific knowledge about both the North American and Eurasian beaver species. The Beaver is designed to satisfy the curiosity and answer the questions of anyone with an interest in these animals, from students who enjoy watching beaver ponds at nature centers to homeowners who hope to protect their landscaping. Photographs taken by the authors document every aspect of beaver behavior and biology, the variety of their constructions, and the habitats that depend on their presence. Beaver facts: Just as individual beavers shape their immediate surroundings, so did the distribution of beavers across North America influence the paths of English and French explorers and traders. As a result of the fur trade, beavers were wiped out across large areas of the United States. Reintroduction efforts led to the widespread establishment of these resilient animals, and now they are found throughout North America, Europe, and parts of the southern hemisphere. Beaver meadows provided early settlers with level, fertile pastures and hayfields. Based on the fossil record, the smallest extinct beaver species were the size of a muskrat, and the largest may have reached the size of a black bear (five to six times as large as today's North American beavers). Beaver-gnawed wood has been found alongside the skeleton of a mastodon. Some beavers remain in the home lodge for an extra year to assist their parents in raising younger siblings. They feed, groom, and guard the newborn kits. In 1600, beaver ponds covered eleven percent of the upper Mississippi and Missouri Rivers' watershed above Thebes, Illinois. Restoring only 3 percent of the original wetlands might suffice to prevent catastrophic floods such as those in the early 1990s."

Download or read book Ecology of a Managed Terrestrial Landscape written by Ajith H. Perera and published by UBC Press. This book was released on 2011-11-01 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing popularity of the broad, landscape-scale approach to forest management represents a dramatic shift from the traditional, stand-based focus on timber production. Ecology of a Managed Terrestrial Landscape responds to the increasing need of forest policy developers, planners, and managers for an integrated, comprehensive perspective on ecological landscapes. The book examines the "big picture" of ecological patterns and processes through a case study of the vast managed forest region in Ontario. The contributors synthesize current landscape ecological knowledge of this area and look at gaps and future research directions from several points of view: spatial patterns, ecological functions and processes, natural disturbances, and ecological responses to disturbance. They also discuss the integration of landscape ecological knowledge into policies of forest management policies, particularly with respect to Ontario's legislative goals of forest sustainability. Ecology of a Managed Terrestrial Landscape is the first book to describe the landscape ecology of a continuously forested landscape in a comprehensive manner. It is written for instructors and students in forest management, wildlife ecology, and landscape ecology, and for forest managers, planners, and policy developers in North America.

Download or read book The Boreal Ecosystem written by James A. Larsen and published by Elsevier. This book was released on 2013-09-03 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Boreal Ecosystem presents an overview of the state of knowledge on the boreal forest region of North America, with extensive reference to the boreal regions of Europe and Asia. Initial sections of this book deal with aspects of the floristic composition and evolutionary history of the boreal vegetation. These introduce subsequent discussions on the processes at work in vegetation, soils, and the atmosphere—in short, with the boreal forest as an ecosystem, the sum total of the influences of many closely interlaced biotic and physical factors. These include not only plant species that make up the visible vegetation but also nutrients, soil, temperature, rainfall, progression of the seasons, soil microflora, arthropods, insects, and larger animals such as marten, otter, beaver, moose, caribou, bear, and wolf, and man. All are closely linked strands in the web of life, a web apart from, yet dependent on and influencing, the raw physical environment. This book should serve as an introduction and reference source to its audience: undergraduate and graduate students in the biological and ecological disciplines, research workers in these fields as well as in related areas such as soil science, agronomy, genetics, and climatology; in short, everyone with an interest in boreal ecology.

Book excerpt: Over a continent and three centuries, American livestock owners destroyed wolves to protect the beasts that supplied them with food, clothing, mobility, and wealth. The brutality of the campaign soon exceeded wolves’ misdeeds. Wolves menaced property, not people, but storytellers often depicted the animals as ravenous threats to human safety. Subjects of nightmares and legends, wolves fell prey not only to Americans’ thirst for land and resources but also to their deeper anxieties about the untamed frontier. Now Americans study and protect wolves and jail hunters who shoot them without authorization. Wolves have become the poster beasts of the great American wilderness, and the federal government has paid millions of dollars to reintroduce them to scenic habitats like Yellowstone National Park. Why did Americans hate wolves for centuries? And, given the ferocity of this loathing, why are Americans now so protective of the animals? In this ambitious history of wolves in America—and of the humans who have hated and then loved them—Jon Coleman investigates a fraught relationship between two species and uncovers striking similarities, deadly differences, and, all too frequently, tragic misunderstanding.

Download or read book Experiments in Consilience written by Frances Westley and published by Island Press. This book was released on 2013-05-10 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his 1998 book Consilience, E.O. Wilson set forth the idea that integrating knowledge and insights from across the spectrum of human study -- the humanities, social science, and natural sciences -- is the key to solving complex environmental and social problems. Experiments in Consilience tells the unique story of a pathbreaking effort to apply this theoretical construct in a real-world setting. The book describes the work of the Biodiversity Research Network, a team of experts from the United States and Canada brought together to build interdisciplinary connections and stimulate an exchange of expertise. Team members sought to understand the ecology and population dynamics of key species in particular ecosystems, to understand the impact of human populations on those species and ecosystems, and to develop tools and processes for involving a greater variety of stakeholders in conservation efforts. In order to keep the experiment grounded, the network focused on a single type of conservation planning workshop run by a single organization -- the Population and Habitat Viability Assessment Workshop (PHVA) of the IUCN-sponsored Conservation Breeding Specialist Group (CBSG). The book combines sections on the theoretical underpinnings of relevant concepts in population biology, simulation modeling, and social science with detailed descriptions of six PHVA workshops conducted on different species across four continents. A concluding chapter examines the lessons learned, which have application to both theory and practice, including reflections on interdisciplinarity, integrated risk assessment, and future directions for research and action. Through the combination of theory and application, combined with frank discussions of what the research network learned -- including both successes and failures -- the book offers fresh ideas on how to improve on-the-ground conservation decisionmaking. Experiments in Consilience offers a one-of-a-kind overview and introduction to the challenges of cross-disciplinary analysis as well as cross-functional, cross-disciplinary and cross-sectoral action. It centers on the problem of conserving endangered species while telling the story of a new form of organizing for effective risk assessment, recommendation, and action.

Download or read book The Serengeti Lion written by George B. Schaller and published by University of Chicago Press. This book was released on 2009-10-15 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on three years of study in the Serengeti National Park, George B. Schaller’s The Serengeti Lion describes the vast impact of the lion and other predators on the vast herds of wildebeest, zebra, and gazelle for which the area is famous. The most comprehensive book available on the lion, this classic work includes the author’s findings on all aspects of lion behavior, including its social system, population dynamics, hunting behavior, and predation patterns. “If you have only enough time to read one book about field biology, this is the one I recommend.”—Edward O. Wilson, Science “This book conveys not only the fascination of its particular study of lion behavior but the drama and wonder and beauty of the intimate interdependence of all living things.”—Saturday Review “This is an important book, not just for its valuable information on lions, but for its broad, open, and intelligent approach to problems that cut across the fields of behavior, populations, ecology, wildlife management, evolution, anthropology, and comparative biology.”—Richard G. Van Gelder, Bioscience
