Download or read book Vegetation Science in Forestry written by Elgene E. O. Box and published by Springer Science & Business Media. This book was released on 1995-01-31 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than a decade has passed since Professor Gisela Jahn completed Volume 12 of the Handbook of Vegetation Science, dealing with the application of vegetation science in forestry, mostly European forestry. The volume was well received by the critics with the exception that they wanted a more diversified demonstration of forestry-related vegetation science work and a wider representation of forest types from different continents. The topics covered in this volume, 12/1, widen the scope of vegetation science work in forestry over the phytosociological work which was the main focus in the Handbook as perceived by Dr Tüxen. Section 1. Overview T. Kira: Forest Ecosystems of East and Southeast Asia in a Global Perspective; E.O. Box: Climatic Relations of the Forests of East and Southeast Asia; K. Iwatsuki: Species Diversity in East Asia in Global Perspective. The remaining contributions are divided into the following sections: Evergreen Forest Region; Summergreen Forest Region; Montane/Boreal Region; Tropical Forest Region.

Download or read book Invasive Alien Species written by Michael R. Ielmini and published by John Wiley & Sons. This book was released on 2021-04-21 with total page 1488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jedes Jahr breiten sich invasive gebietsfremde Arten in neue Ökosysteme aus. Die von den Eindringlingen verursachten Auswirkungen können sich in kürzester Zeit bemerkbar machen und verheerend sein. Das Thema der invasiven gebietsfremden Arten ist umfassend, komplex und auf verschiedenen Ebenen von globaler Bedeutung. Verschärft wird es durch die Globalisierung der Weltwirtschaft und den zunehmenden Handel, durch den die natürlichen Barrieren für den Transfer von Arten durchbrochen werden. Invasive gebietsfremde Arten bedrohen die weltweite Nahrungsmittelversorgung, die Qualität und Verfügbarkeit von Trinkwasser sowie die Stromproduktion und -versorgung. Zusammen mit den zusätzlichen Risiken durch den globalen Klimawandel ist die weltweite Homogenisierung von Pflanzen, Tieren und Mikroben ein wesentlicher Faktor für den sich verschlechternden Gesundheitszustand der Ökosysteme und die nachlassenden Ökosystemdienstleistungen überall auf der Welt. Um dieser Entwicklung entgegenzuwirken, besteht die dringende Notwendigkeit einer einheitlichen Ausrichtung von Regierungen, Kulturen und Programmen und einer besseren grenzüberschreitenden Koordination. Nur so lassen sich die vielfältigen Bedrohungen durch invasive gebietsfremde Arten für die Umwelt, die Wirtschaft und die Gesundheit von Pflanzen und Tieren sowie insbesondere die menschliche Gesundheit effektiv bekämpfen. Dieses vierbändige Werk ist das erste, das einen umfassenden Satz nützlicher Materialien zu den zentralen Themen bereitstellt, um die gesamte globale Bedrohung durch invasive gebietsfremde Arten sowie die vielfältigen Probleme in verschiedenen Teilen der Welt deutlich zu machen, und es enthält Material, in dem potenziell replizierbare Lösungen zur Überwindung dieser Bedrohungen aufgezeigt werden. Das Werk betont die Bedrohung durch invasive gebietsfremde Arten auch im Sinne eines globalen ?Aufrufs zum Handeln?. Invasive Arten kennen keine Grenzen. Daher hoffen wir, dass wir durch die Zusammenstellung von Material, das unterschiedliche wissenschaftliche und gesellschaftliche Standpunkte aus aller Welt berücksichtigt, sowie durch die Vermittlung von Erkenntnissen und Beispielen zu einer Vielzahl damit zusammenhängender Themen das globale Bewusstsein stärken und einheitliche nationale Reaktionen auf die Bedrohung durch invasive gebietsfremde Arten fördern können.

This book was released on 2005-03-30 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: The plant fossil record indicates that the genus Metasequoia was widely distributed throughout the Northern Hemisphere from the early Late Cretaceous to the Plio-Pleistocene. Today the genus has shrunk to one species with approximately 5,000 mature individuals in southeastern China’s Xiahoe Valley. This book distills the current understanding of the biology, ecology and physiology of fossil and living Metasequoia, current research directions and problems that remain unresolved.

Download or read book Biological Diversity written by Michael A. Huston and published by Cambridge University Press. This book was released on 1994-09-15 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The key to preserving and managing biodiversity is understanding which processes are important at different scales, and how changes affect different components of biodiversity. In this book, existing theories on diversity are synthesised into a logical framework. Global and landscape-scale patterns of biodiversity are described in the first section. In the second, the spatial and temporal dynamics of diversity are emphasised. The third section develops an integrated set of mechanistic explanations for diversity patterns at the levels of population, community, ecosystem and landscape. Finally, case studies examine diversity patterns in marine and terrestrial ecosystems and the effects of biological invasions. The book concludes with a discussion of the economics of preserving biological diversity. This book will interest research workers and students of ecology, biology and conservation.

Download or read book Panbiogeography written by Robin C. Craw and published by Oxford University Press. This book was released on 1999-04-15 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biogeography is a diverse subject, traditionally focusing on the distribution of plants and animals at different taxonomic levels, past and present. Modern biogeography also puts emphasis on the ecological character of the world vegetation types, and on the evolving relationship between humans and their environment. Panbiogeography describes a new synthesis of sciences of plant and animal distribution. The book emphasizes that the geographical patterns of animal and plant distribution contribute directly to the understanding and interpretation of evolutionary history. Geographic location is reintroduced as a critical element of both biogeography and evolutionary biology. The authors present chapters exploring the roles of geology, ecology, evolution in panbiogeographic theory, and introduce new methods, modes of classification, and ways of measuring biodiversity.

Download or read book Mangrove Ecology Silviculture and Conservation written by Peter Saenger and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mangroves are a fascinating group of plants that occur on tropical and subtropical shorelines of all continents, where they are exposed to saltwater inundation, low oxygen levels around their roots, high light and temperature conditions, and periodic tropical storms. Despite these harsh conditions, mangroves may form luxuriant forests which are of significant economic and environmental value throughout the world - they provide coastal protection and underpin fisheries and forestry operations, as well as a range of other human activities. This book provides an up-to-date account of mangrove plants from around the world, together with silvicultural and restoration techniques, and the management requirements of these communities to ensure their sustainability and conservation. All aspects of mangroves and their conservation are critically re-examined. Those activities which threaten their ongoing survival are identified and suggestions are offered to minimise their effects on these significant plant communities.
