Grazing animals enjoy an ambiguous reputation in the field of nature conservation. Livestock are often treated as a scourge, yet native large herbivores form the prime attraction of many a reserve. This book gives the first comprehensive overview of the use of grazing as a tool in conservation management. Considering in turn the ecological and historical background, the impact of grazing on community structure, management applications and future prospects, this book examines issues such as the role of herbivores as keystone species, the assessment of habitat quality and the function of scientific models in advancing grazing management. Large herbivores are shown to be potentially powerful allies in the management of nature reserves, particularly in the maintenance, enhancement or restoration of biodiversity. Grazing and Conservation Management will appeal to conservation biologists and rangeland managers, providing them with a clearer understanding of grazing and conservation management.
In view of the massive change in the area of distribution of many world biota across classical biogeographical realms, and of the drastic restructuring of the biotic components of numerous ecosystems, the Scientific Committee on Problems of the Environment (SCOPE) decided at its general Assembly in Ottawa, Canada, in 1982 to launch a project on the 'Ecology of Biological Invasions'. Several regional meetings were subsequently organized within the framework of SCOPE, in order to single out the peculiarities of the invasions that took place in each region, the behaviour of their invasive species and the invasibility of their ecosystems. Most noteworthy among such workshops were one in Australi...

This book provides a comprehensive and up-to-date description of the Josephson effect, a topic of never-ending interest in both fundamental and applied physics. In this volume, world-renowned experts present the unique aspects of the physics of the Josephson effect, resulting from the use of new materials, of hybrid architectures and from the possibility of realizing nanoscale junctions. These new experimental capabilities lead to systems where novel coherent phenomena and transport processes emerge. All this is of great relevance and impact, especially when combined with the didactic approach of the book. The reader will benefit from a general and modern view of coherent phenomena in weakly-coupled superconductors on a macroscopic scale. Topics that have been only recently discussed in specialized papers and in short reviews are described here for the first time and organized in a general framework. An important section of the book is also devoted to applications, with focus on long-term, future applications. In addition to a significant number of illustrations, the book includes numerous tables for comparative studies on technical aspects.

From the point of view of plant geography, including various aspects of chorology, one of the prerequisites of successful large-scale synthesis of this type is and adequate flora covering the area in question, and providing a common language in respect to the delimitation and nomenclature of the taxa to be treated. This essential conditon is now fulfilled for Europe by the current volumes of Flora Europaeae. This new series of compendium atlas volumes makes available allthe distribution maps so far produced by the commitee for mapping the flora of Europe in convenient library editons and in the format and livery of Flora Europaeae. A thirds volume containing the caryophllacaeae is in preparation.
The first and so far only Plant Geography of Chile was written about 100 years ago, since when many things have changed: plants have been renamed and reclassified; taxonomy and systematics have experienced deep changes as have biology, geography, and biogeography. The time is therefore ripe for a new look at Chile’s plants and their distribution. Focusing on three key issues – botany/systematics, geography and biogeographical analysis – this book presents a thoroughly updated synthesis both of Chilean plant geography and of the different approaches to studying it. Because of its range – from the neotropics to the temperate sub-Antarctic – Chile’s flora provides a critical insight into evolutionary patterns, particularly in relation to the distribution along the latitudinal profiles and the global geographical relationships of the country’s genera. The consequences of these relations for the evolution of the Chilean Flora are discussed. This book will provide a valuable resource for both graduate students and researchers in botany, plant taxonomy and systematics, biogeography, evolutionary biology and plant conservation.
Climate change is one of the most severe dangers for mankind worldwide. Beside the temperature increase, the sea level will rise and flood wide coastal areas, which is already remarkable today. The effects will be dramatic, in particular, at coasts with low elevation gradients such as at the German coasts of the North and Baltic Sea. The impact will be not only severe for coastal people, but still more for the unique coastal ecosystems, which harbors many plant and animal species that are already endangered today. This book focuses on the coastal terrestrial ecosystems of the German North and Baltic Sea. It describes the reactions of plants and animals (i.e. spiders, carabid beetles, bees an...
