Available in PDF, EPUB and Kindle. Book excerpt: By affecting the ecological, pecuniary and aesthetic productivity of ecosystems, invasive species (IS) increase production and management costs to business, while straining public agencies' budgets with monitoring, enforcement and management efforts. Understanding invasion pathways or vectors, and identifying costs and benefits of alternative management strategies are critical to public and private decision making in agriculture, natural resource and recreation industries. This study develops an integrated spatial framework to measure IS risk and cost-efficiency of alternative IS management strategies. For a given spatial unit, the framework weighs expected damages, based on measured IS risk, against the cost of alternative management strategies, i.e. spatial cost minimization. The study then applied the spatial cost minimization framework to the case of New Zealand mudsnails, Potamopyrgus antipodarum, (NZMS) in the Pacific Northwest (PNW) using data from a variety of sources. The first stage of the integrated framework is the measurement of NZMS establishment risk, which is estimated as a combination of anthropogenic introduction risk and habitat suitability risk. Since recreational boats are a main vector to disperse NZMS, the normalized boat flows in the PNW states--Idaho, Oregon, and Washington--are used as a proxy for the anthropogenic introduction risk. An environmental niche model then revealed the relationship between environmental features and NZMS presence, i.e. habitat suitability risk. Results suggest that distance, area size, water body concentration, and accessibility are major determinants of PNW recreational boat flows. Environmental characteristics such as elevation, geologic features, precipitation in January, March, and September, as well as the minimum temperature of June, July, and August, and the maximum temperature of June, August, and October are important determinants of PNW's habitat suitability for NZMS. Potential damages arising from NZMS include anglers' utility loss, which is caused by aquatic habitat degradation due to NZMS invasion, and biofouling influence on hydroelectricity plants, drinking water treatment plants, and boats. Because NZMS economic damages and related management cost are not yet fully identified in the literature, damages and management cost of zebra mussels serve as proxies for those of NZMS. Expected damages are then derived as the product of NZMS establishment risk from the first stage and potential damages noted above. Statewide management cost information is compiled from a phone survey of PNW invasive species field managers. Statewide and local management strategies are prevention, early detection and rapid response and its follow-up (EDRR plus) and ex-post management without EDRR. Local strategies additionally include boater decontamination and fish hatchery prevention efforts. Finally, the spatial cost minimization problem evaluates expected damages against the cost of each alternative management strategy (statewide and local). Solutions to this minimization problem, i.e. cost-efficient strategies, are derived for individual spatial units in each of the three PNW states. Reflecting uncertainty in the relationship between NZMS impacts and management, the spatial cost minimization is solved under different scenarios: unconstrained, NZMS damages are a fraction of those of zebra mussels, variation in the effectiveness of statewide and local management strategies, a budget constraint, and targeted NZMS risk level constraint. Results show that statewide prevention, local boater decontamination and fish hatchery prevention are the cost-efficient strategies for managing NZMS in the Pacific Northwest in most cases.

This book was released on 2021-02-01 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This new volume on Biological Invasions deals with both plants and animals, differing from previous books by extending from the level of individual species to an ecosystem and global level. Topics of highest societal relevance, such as the impact of genetically modified organisms, are interlinked with more conventional ecological aspects, including biodiversity. The combination of these approaches is new and makes compelling reading for researchers and environmentalists.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Fifty Years of Invasion Ecology written by David M. Richardson and published by John Wiley & Sons. This book was released on 2011-01-18 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasion ecology is the study of the causes and consequences of the introduction of organisms to areas outside their native range. Interest in this field has exploded in the past few decades. Explaining why and how organisms are moved around the world, how and why some become established and invade, and how best to manage invasive species in the face of global change are all crucial issues that interest biogeographers, ecologists and environmental managers in all parts of the world. This book brings together the insights of more than 50 authors to examine the origins, foundations, current dimensions and potential trajectories of invasion ecology. It revisits key tenets of the foundations of invasion ecology, including contributions of pioneering naturalists of the 19th century, including Charles Darwin and British ecologist Charles Elton, whose 1958 monograph on invasive species is widely acknowledged as having focussed scientific attention on biological invasions.
