Multiple Stressors in River Ecosystems: Status, Impacts and Prospects for the Future provides a comprehensive and current overview on the topic as written by leading river scientists who discuss the relevance of co-occurring stressors for river ecosystems. River ecosystems are subject to multiple stressors that threaten their ecological status and the ecosystem services they provide. This book updates the reader's knowledge on the response and management of river ecosystems to multi-stress situations occurring under global change. Detailing the risk for biodiversity and functioning in a case-study approach, it provides insight into methodological issues, also including the socioeconomic implications. - Presents a case study approach and geographic description on the relevance of multiple stressors on river ecosystems in different biomes - Gives a uniquely integrated perspective on different stressors, including their interactions and joint effects, as opposed to the traditional one-by-one approach - Compiles state-of-the-art methods and technologies in monitoring, modeling and analyzing river ecosystems under multiple stress conditions
Contains both an index of vernacular names and an index of scientific names of the trees.
This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.
This practical manual is an authoritative guide to olive propagation, providing extended information on seed germination, rooting of cuttings, grafting and micropropagation. The authors describe each topic in detail and discuss the relative advantages and disadvantages of each procedure. The Olive Propagation Manual has been developed to take into account the future demand for olive oil, which is expected to increase to three million tonnes annually over the next 10 years. Such volumes will require active farming programs and olive trees for new orchards and the replacement of olive trees in existing orchards. As the olive industry moves from traditional manual methods to mechanised operations, planting stock will need to be developed to meet future challenges. Varietal selection will need to be directed to clones that are early bearing, disease resistant, able to be mechanically harvested, and produce quality fruit and oil. Each of these issues are addressed throughout this book. The Olive Propagation Manual explores historical perspectives, traditional methods and state-of-the-art olive propagation including theoretical explanations and all practical aspects.
