This book was released on 2003-08-01 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2002 in the subject Biology - Ecology, grade: 2 (B), University of Vienna (Institute for Ecology), language: English, abstract: “If all the brown bears are gone from the landscape we would be spiritually impoverished.” was the response from a researcher when she was asked why we should protect bears. This is only one of numerous answers to this question. Bears engage our interest, as do few other wild animals. But brown bears are not simply fascinating animals, they also play an important role in the ecosystem. They are considered 'sustainable farmers'. Many species, both plants and animals, profit by them. Brown bears dig much for food and thereby they stimulate plants to reproduce. Some Canadian scientists even consider grizzlies, conspecific with the Eurasian brown bear, to be an ecological keystone. “Without the grizzlies atop the food chain,” they say, “the West’s delicate mountain ecosystem would crumble.” They think that it could set off a chain reaction that would see other large animals become extinct. Coyotes and other predators would move in and do serious damage to the ungulate population. Grizzlies prey on live ungulates far less than coyotes or wolves. The bears ́ presence keeps other predators at bay. Other scientists such as Stephen Herrero, the head of the Eastern Slopes Grizzly Bear Project, do not believe in such dire predictions but Stephen Herrero agrees that the relationship between bears and the rest of the ecosystem is very complex (Sillars 1998). However, large carnivores, like grizzlies, have been considered indicators of health or integrity of an ecosystem (Paquet and Wierzchowski 1997a) and thus make them useful focal species for large-scale conservation. Landscapes that retain viable populations of brown bears are often ones where natural vegetation predominates, where most native species can still be found, and where ecological processes operate essentially as they have done for a long time (Paquet and Jack Wierzchowski 1997a). Habitats of brown bears can be huge, but vary greatly on individuals. A modest female can manage to live within a few square kilometres, and long distance travellers among grizzlies, that are mostly males, could need up to 1500 km2, which is as big as Kootenay National Park in Alberta or only a bit smaller than the Austrian “Hohe Tauern National Park”, the biggest national park in Central Europe.

Download or read book High Mountain Conservation in a Changing World written by Jordi Catalan and published by Springer. This book was released on 2017-08-03 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.
Download or read book Rewilding European Landscapes written by Henrique M. Pereira and published by Springer. This book was released on 2015-05-04 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some European lands have been progressively alleviated of human pressures, particularly traditional agriculture in remote areas. This book proposes that this land abandonment can be seen as an opportunity to restore natural ecosystems via rewilding. We define rewilding as the passive management of ecological successions having in mind the long-term goal of restoring natural ecosystem processes. The book aims at introducing the concept of rewilding to scientists, students and practitioners. The first part presents the theory of rewilding in the European context. The second part of the book directly addresses the link between rewilding, biodiversity, and habitats. The third and last part is dedicated to practical aspects of the implementation of rewilding as a land management option. We believe that this book will both set the basis for future research on rewilding and help practitioners think about how rewilding can take place in areas under their management.

Download or read book The Green Belt of Europe written by Andrew Terry and published by IUCN. This book was released on 2006 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Iron Curtain, running from the Barents Sea to the Black Sea, divided Europe for almost 40 years and no activity was allowed in this "forbidden" zone. When it fell in 1989, it left a strip of land that runs the entire length of Europe and that has remained comparatively undisturbed - a green belt. The Green Belt initiative aims to integrate this entire strip of land with its key habitats and ecological areas as part of an international network of valuable ecosystems. This book provides background information on the initiative, reviews current activities in a number of case studies and looks at how the initiative can fit into current and future global efforts to protect European biodiversity.
Download or read book The Economics of Ecosystems and Biodiversity Ecological and Economic Foundations written by Pushpam Kumar and published by Taylor & Francis. This book was released on 2012-12-20 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human well-being relies critically on ecosystem services provided by nature. Examples include water and air quality regulation, nutrient cycling and decomposition, plant pollination and flood control, all of which are dependent on biodiversity. They are predominantly public goods with limited or no markets and do not command any price in the conventional economic system, so their loss is often not detected and continues unaddressed and unabated. This in turn not only impacts human well-being, but also seriously undermines the sustainability of the economic system. It is against this background that TEEB: The Economics of Ecosystems and Biodiversity project was set up in 2007 and led by the United Nations Environment Programme to provide a comprehensive global assessment of economic aspects of these issues. This book, written by a team of international experts, represents the scientific state of the art, providing a comprehensive assessment of the fundamental ecological and economic principles of measuring and valuing ecosystem services and biodiversity, and showing how these can be mainstreamed into public policies. This volume and subsequent TEEB outputs will provide the authoritative knowledge and guidance to drive forward the biodiversity conservation agenda for the next decade.

Available in PDF, EPUB and Kindle. Book excerpt: Wildlife and Recreationists defines and clarifies the issues surrounding the conflict between outdoor recreation and the health and well-being of wildlife and ecosystems.

More important, it addresses both research needs and management options to minimize conflicts.
