Mit Agrarholz in die Zukunft: Der Anbau von Baumen als Nutzpflanzen ist nicht nur klimafreundlich, sondern auch profitabel! Die Intensivnutzung von Baumen in der Landwirtschaft gewinnt immer mehr an Bedeutung. Steigende Ol- und Gaspreise machen Holz als Energietrager wirtschaftlich attraktiv und tragen gleichzeitig zum Klimaschutz bei. Die neuesten Erkenntnisse aus drei aktuellen Verbundprojekten (AGROFORST, AGROWOOD, DENDROM) werden fur den Praktiker aufbereitet und alle Aspekte des Wirtschaftskreislaufs angesprochen: rechtliche Rahmenbedinungen, Hinweise zu Fordergeldern, Planung, Anlage und den Betrieb der Pflanzung, bis hin zur optimalen Vermarktung der Produkte. Neben betriebswirtschaftlichen Erwagungen steht die okologische Gesamtbilanz dieser Form des Pflanzenbaus im Vordergrund, die auch den Flachenverbrauch und ein durch neu geschaffene «Baumfelder» verandertes Landschaftsbild mit einbezieht.

The Moss Physcomitrella patens has rapidly become an experimental model of choice for many aspects of molecular, cell and developmental biology in plant sciences. With a recently sequenced genome, which has further fuelled interest and research, Physcomitrella is accruing various new labels, from ‘a green yeast’ to the Drosophila, Caenorhabditis or Zebra fish of plant sciences. A truly international collaboration, this timely volume brings together a selection of chapters each composed by experts in their field. The chapters included cover a broad range: From those using P. patens as a marker against other species for evolutionary or ecological studies To those investigating the unique features of P. patens, e.g. gene targeting To those using moss, either as a comparator for other organisms or because of the ease of study in moss, to investigate standard biological processes This landmark publication is essential reading for anyone studying plant evolutionary biology, genomics, molecular and cell biology and genetics. Libraries in all universities and research establishments, where biological and agricultural sciences are studied and taught, should have copies of this important book on their shelves.

Gravel-Bed Rivers: Processes, Tools, Environments presents a definitive review of current knowledge of gravel-bed rivers, derived from the 7th International Gravel-bed Rivers Workshop, the 5-yearly meeting of the world’s leading authorities in the field. Each chapter in the book has been specifically commissioned to represent areas in which recent progress has been made in the field. The topics covered also represent a coherent progression through the principal areas of the subject (hydraulics; sediment transport; river morphology; tools and methods; applications of science). Definitive review of the current knowledge of gravel-bed rivers Coverage of both fundamental and applied topics Edited by leading academics with contributions from key researchers Thoroughly edited for quality and consistency to provide coherent and logical progression through the principal areas of the subject.

The Banggai cardinalfish, Pterapogon kauderni, is a fascinating species that possesses a series of remarkable biological characteristics making it unique among coral reef fishes. It has been the focus of studies in reproduction, ecology, population genetics and evolution. In addition, since its rediscovery in the late 1990s, it has become tremendously popular in the international ornamental fish trade, and indiscriminate collecting has led to its inclusion in the 2007 IUCN Red List as an endangered species. This book is divided into three main parts: a general introduction to the fish, including a historical synopsis with an overview of the Banggai Archipelago; a comprehensive treatment of the species’ natural history (distribution, morphology, reproduction, embryology, ecology, genetics, systematics and evolution); an account of the conservation of the species, including descriptions of its fishery, attempts to protect it under CITES, and introduction programmes. The book also includes an appendix offering information on captive breeding, juvenile mortality reduction, and common diseases. This book is a unique resource for ichthyology students and researchers working on fish biology, ecology and conservation, and for marine ornamental fish hobbyists and aquarium professionals.

This book is intended for those with an academic, scientific and practical interest in river conservation and management. It provides an overview of how changes in legislation, policies, institutional responsibilities, science, technology, practical techniques and public perception have influenced how rivers have been managed over the past 20 years and the challenges that lie ahead during the next 20 years. The book is based on the international conference River Conservation and Management:20 Years On held at York. Thirty-one chapters, with contributions from North and South America, Europe, Asia and Australasia provide a wide-ranging perspective on this complex but profoundly important subject. Following an introduction that chronicles the most important contextual changes, the book is organized into four broad topics: Catchment management, ecosystem integrity and the threats to river ecosystems – this covers progress on understanding and addressing the pressures affecting rivers, many of which will be amplified by climate change and increasing human demands for water; Methods and approaches – illustrating some recent techniques that have been developed to assess condition and conservation status across different types of river; Recovery and rehabilitation – providing an insight into the principles, practice, public involvement and institutional networks that support and make improvements to modified river reaches; Integrating nature conservation into wider river management –demonstrating the importance of integrated planning, involvement of local communities and the use of adaptive management in achieving multiple environmental and economic benefits along rivers used for different purposes. The final chapter discusses the challenges faced in dealing with an uncertain future. More than 1200 different references and numerous web-site citations provide the reader with an invaluable source of knowledge on the subject area.

This new edition of Biological Oceanography has been greatly updated and expanded since its initial publication in 2004. It presents current understanding of ocean ecology emphasizing the character of marine organisms from viruses to fish and worms, together with their significance to their habitats and to each other. The book initially emphasizes pelagic organisms and processes, but benthos, hydrothermal vents, climate-change effects, and fisheries all receive attention. The chapter on oceanic biomes has been greatly expanded and a new chapter reviewing approaches to pelagic food webs has been added. Throughout, the book has been revised to account for recent advances in this rapidly changing field. The increased importance of molecular genetic data across the field is evident in most of the chapters. As with the previous edition, the book is primarily written for senior undergraduate and graduate students of ocean ecology and professional marine ecologists.

The new, completely updated edition of the aerial photography classic Extensively revised to address today's technological advances, Aerial Photography and Image Interpretation, Third Edition offers a thorough survey of the technology, techniques, processes, and methods used to create and interpret aerial photographs. The new edition also covers other forms of remote sensing with topics that include the most current information on orthophotography (including digital), soft copy photogrammetry, digital image capture and interpretation, GPS, GIS, small format aerial photography, statistical analysis and thematic mapping errors, and more. A basic introduction is also given to nonphotographic and space-based imaging platforms and sensors, including Landsat, lidar, thermal, and multispectral. This new Third Edition features: Additional coverage of the specialized camera equipment used in aerial photography A strong focus on aerial photography and image interpretation, allowing for a much more thorough presentation of the techniques, processes, and methods than is possible in the broader remote sensing texts currently available Straightforward, user-friendly writing style Expanded coverage of digital photography Test questions and summaries for quick review at the end of each chapter Written in a straightforward style supplemented with hundreds of photographs and illustrations, Aerial Photography and Image Interpretation, Third Edition is the most in-depth resource for undergraduate students and professionals in such fields as forestry, geography, environmental science, archaeology, resource management, surveying, civil and environmental engineering, natural resources, and agriculture.
