Available in PDF, EPUB and Kindle. Book excerpt: Bridging the fields of ecosystem science and landscape ecology, this book integrates Dr. Carol Johnston's research on beaver ecosystem alteration at Voyageurs National Park. The findings about the vegetation, soils, and chemistry of beaver impoundments synthesized in the text provide a cohesive reference useful to wetland scientists, ecosystems and landscape ecologysts, wildlife managers, and students. The beaver, Castor canadensis, is an ecosystem engineer unequaled in its capacity to alter landscapes through browsing and dam building, whose population recovery has re-established environmental conditions that probably existed for millenia prior to its near extirpation by trapping in the 1800s and 1900s. Beavers continue to regain much of their natural range throughout North America, changing stream and forest ecosystems in ways that may be lauded or vilified. Interest in beavers by ecologists remains keen as new evidence emerges about the ecological, hydrological, and biogeochemical effects of beaver browsing and construction. There is a critical need for ecologists and land managers to understand the potential magnitude, persistence, and ecosystem services of beaver landscape transformation. The 88-year record of beaver landscape occupation and alteration documented by Dr. Carol Johnston and colleagues from aerial photography and field work provides a unique resource toward understanding the ecosystem effects and sustainability of beaver activity.

Download or read book Beavers written by Frank Rosell and published by Oxford University Press. This book was released on 2021-10-23 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beavers are represented by two extant species, the Eurasian beaver (Castor fiber) and the North American beaver (Castor canadensis); each has played a significant role in human history and dominated wetland ecology in the northern hemisphere. Their behaviour and ecology both fascinate and perhaps even infuriate, but seemingly never fail to amaze. Both species have followed similar histories from relentless persecution to the verge of extinction (largely through hunting), followed by their subsequent recovery and active restoration which is viewed by many as a major conservation success story. Beavers have now been reintroduced throughout Europe and North America, demonstrating that their role as a keystone engineer is now widely recognised with proven abilities to increase the complexity and biodiversity of freshwater ecosystems. What animals other than humans can simultaneously act as engineers, forest workers, carpenters, masons, creators of habitats, and nature managers? Over the last 20 years, there has been a huge increase in the number of scientific papers published on these remarkable creatures, and an authoritative synthesis is now timely. This accessible text goes beyond their natural history to describe the impacts on humans, conflict mitigation, animal husbandry, management, and conservation. Beavers: Ecology, Behaviour, Conservation, and Management is an accessible reference for a broad audience of professional academics (especially carnivore and mammalian biologists), researchers and graduate students, governmental and non-governmental wildlife bodies, and amateur natural historians intrigued by these wild animals and the extraordinary processes of nature they exemplify.

This book was released on 2012-12-06 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: By the end of the 19th century both beaver species had been extirpated from large portions of their native ranges. The global decline in beaver populations was the direct re sult of exploitation by humans. Now, at the end of the 20th century, protection, manage ment, and reintroduction programs, coupled with a decline in the demand for beaver fur and other products, have allowed beaver populations to increase dramatically. Since bea vers actively modify their local environment their activities can conflict with human land use. Because of this, the beaver, once considered a unique and exotic component of wet lands, is now often considered a nuisance species. The history, as well as the current status, of beaver populations in Europe and North America provide insight into how con servation programs work, and into how humans and wildlife interact. The initial plenary lecture of the Euro-American Mammal Congress (July, 1998) was presented by Dr. Michael L. Rosenzweig, a professor at the University of Arizona. Dr. Rosenzweig discussed how humans have used and continue to use natural resources, in cluding wildlife and wildland. He provided evidence indicating that the current model of reservation conservation could not provide a long-term solution to the human-wild life/wildland conflict. Dr. Rosenzweig emphasized that what is required is a move away from purely exploitive activities (I would call this exploitive ecology) and the develop ment of a reconciliation ecology with wildlife.

Available in PDF, EPUB and Kindle. Book excerpt: An illustrated review of the Northern Great Plains that blends natural history and human history “The most complete, in-depth look at Dakota ecosystems and their history. An absolutely fascinating read!”—Gabe Brown, author of Dirt to Soil W. Carter Johnson and Dennis H. Knight describe the natural and human histories of the Northern Great Plains in this comprehensive and handsomely illustrated book. Covering a vast period of time, they move from geological developments millions of years ago and the effects of glaciers to historical and ecological developments in recent centuries and the effects of agriculture. The book ends with a discussion of the future of this region, mediated by climate change, with recommendations on how to balance agriculture and other pressing needs in the twenty-first century. Johnson and Knight bring decades of experience to chapters on the major ecosystems of the Dakotas. Written for readers with varying backgrounds, and with discussions of the Prairie Pothole Region, the Missouri River, grasslands, woodlands, the Black Hills, and rivers, lakes, and wetlands, the book is unique and will become a long-lasting source of information. Readers will appreciate the plentiful photographs and other color illustrations.

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 Müller-Schwarze gathers 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.

Book excerpt: "In response to climate warming, many species are shifting their distributions poleward, leading to the introduction of new species in Northern ecosystems. In the subarctic, woody shrubs have become more abundant and robust, water bodies have shifted from bedfast ice to floating ice regimes during winter, and melting permafrost has changed the topography and hydrology, facilitating pond development. Consequently, North American beaver (Castor canadensis) populations have begun entering the "greened" tundra ecosystem across North America. As a specialized rodent that modifies ecosystems by foraging woody vegetation and damming riverine habitats, completely altering forest composition and hydrology, it is important to understand the drivers and predictors of low arctic beaver establishment to inform conservation and wildlife management practices. In this thesis, I reviewed our existing understanding of which climatic, environmental, and vegetation factors influence beaver abundance, establishment, habitat selection, and foraging behaviour in the literature. This review highlighted that vegetation composition and traits, such as stem size and abundance, were considered as strong proxies for beaver forage and abundance, while climate, environment, and geomorphology increase the potential of habitat selection and establishment. Additionally, beavers' requirements change over time as the rodent completely alter their habitats and forest structure through ecosystem engineering. Therefore, it is crucial to distinguish between habitat characteristics before and after establishments to better understand the drivers of beaver colonization and abundance. Secondly, I aimed to address how these environmental and vegetation factors affect the functional adaptation of beavers over their Canadian distribution. Using geometric morphometrics, I tested the hypothesis that beaver skulls are locally adapted to their environment by relating environmental factors to functional traits in beaver skulls across Canada. I found that beaver functional morphology is significantly associated with vegetation and climate variables. Specifically, functional changes in the masticatory regions of the skull are related with changes in forest composition, biomass, ecozone, and climate, suggesting that beavers are adapted to their habitat based on selective foraging. These findings provide insight into the adaptive potential of newly established beavers in the sub-arctic to better predict future range shifts and provide information for future management practices"--
