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 Metacommunity Ecology written by Mathew A. Leibold and published by Princeton University Press. This book was released on 2018 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metacommunity ecology links smaller-scale processes that have been the provenance of population and community ecology—such as birth-death processes, species interactions, selection, and stochasticity—with larger-scale issues such as dispersal and habitat heterogeneity. Until now, the field has focused on evaluating the relative importance of distinct processes, with niche-based environmental sorting on one side and neutral-based ecological drift and dispersal limitation on the other. This book moves beyond these artificial categorizations, showing how environmental sorting, dispersal, ecological drift, and other processes influence metacommunity structure simultaneously. Mathew Leibold and Jonathan Chase argue that the relative importance of these processes depends on the characteristics of the organisms, the strengths and types of their interactions, the degree of habitat heterogeneity, the rates of dispersal, and the scale at which the system is observed. Using this synthetic perspective, they explore metacommunity patterns in time and space, including patterns of coexistence, distribution, and diversity. Leibold and Chase demonstrate how these processes and patterns are altered by micro- and macroevolution, traits and phylogenetic relationships, and food web interactions. They then use this scale-explicit perspective to illustrate how metacommunity processes are essential for understanding macroecological and biogeographical patterns as well as ecosystem-level processes. Moving seamlessly across scales and subdisciplines, Metacommunity Ecology is an invaluable reference, one that offers a more integrated approach to ecological patterns and processes.

Download or read book Singing Wilderness written by Sigurd F. Olson and published by Knopf. This book was released on 2012-05-30 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: To do with the calling of loons, with northern lights, and the great silences of land lying northwest of Lake Superior. It is concerned with the simple joys, the timelessness and perspective found in a way of life which is close to the past. I have heard the singing in many places, but I seem to hear it best in the wilderness lake country of the Quetico-Superior, where travel is still by pack and canoe over the ancient trails of the Indians and voyageurs." Thus the author sets the theme and tone of this enthralling book of discovery about one of the few great primitive areas in our country which have withstood the pressures of civilization. Acute natural perceptivity and a profound knowledge of the relationships to be found in nature combine here in vivid evocations of the sights, the sounds, the vast stillnesses, and the events of the wilderness as the seasons succeed each other. But Mr. Olson is not content merely to "describe; he probes for meanings that will lead the reader to a different and more revealing way of looking at the out-of-doors and to a deeper sense of its eternal values. In each of the thirty-four chapters of The Singing Wilderness he has sought to capture an essential quality of our magnificent lake and forest heritage. He shows us what can be read from the rocks of the great Canadian Shield; he offers a delightful essay on the virtues of pine knots as fuel; he writes of the ways of a canoe, of flashing trout in the pools of the Isabella, of tamarack bogs, caribou moss, the flight of wild geese, timber wolves, and the birds of the ski trails. And much more, with something to satisfy every taste for wilderness experience. Superbly illustrated with 38 black-and-white drawings by Francis Lee Jaques, The Singing Wilderness is a book that no lover of nature will want to be without. To anyone who contemplates a vacation in the lake country of northern Minnesota and adjoining Canada, it is the perfect vade mecum.

Download or read book Hudson Bay Bound written by Natalie Warren and published by U of Minnesota Press. This book was released on 2021-02-02 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: The remarkable eighty-five-day journey of the first two women to canoe the 2,000-mile route from Minneapolis to Hudson Bay Unrelenting winds, carnivorous polar bears, snake nests, sweltering heat, and constant hunger. Paddling from Minneapolis to Hudson Bay, following the 2,000-mile route made famous by Eric Sevareid in his 1935 classic Canoeing with the Cree, Natalie Warren and Ann Raiho faced unexpected trials, some harrowing, some simply odd. But for the two friends—the first women to make this expedition—there was one timeless challenge: the occasional pitfalls that test character and friendship. Warren’s spellbinding account retraces the women’s journey from inspiration to Arctic waters, giving readers an insider view from the practicalities of planning a three-month canoe expedition to the successful accomplishment of the adventure of a lifetime. Along the route we meet the people who live and work on the waterways, including denizens of a resort who supply much-needed sustenance; a solitary resident in the wilderness who helps plug a leak; and the people of the Cree First Nation at Norway House, where the canoeists acquire a furry companion. Describing the tensions that erupt between the women (who at one point communicate with each other only by note) and the natural and human-made phenomena they encounter—from islands of trash to waterfalls and a wolf pack—Warren brings us into her experience, and we join these modern women (and their dog) as they recreate this historic trip, including the pleasures and perils, the sexism, the social and environmental implications, and the enduring wonder of the wilderness.
