Book Description
This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.
Ecological Effects of Water-level Fluctuations in Lakes
Author: Karl M. WantzenPublisher: Springer Science & Business Media
ISBN: 1402091923
Category : Technology & Engineering
Languages : en
Pages : 184
Book Description
Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.
The Structural Conservation of Panel Paintings
Author: Kathleen DardesPublisher: Getty Publications
ISBN: 0892363843
Category : Art
Languages : en
Pages : 582
Book Description
This volume presents the proceedings of an international symposium organized by the Getty Conservation Institute and the J. Paul Getty Museum. The first conference of its kind in twenty years, the symposium assembled an international group of conservators of painted panels, and gave them the opportunity to discuss their philosophies and share their work methods. Illustrated in color throughout, this volume presents thirty-one papers grouped into four topic areas: Wood Science and Technology, History of Panel-Manufacturing Techniques, History of the Structural Conservation of Panel Paintings, and Current Approaches to the Structural Conservation of Panel Paintings.
