Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2017-08-11 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Download or read book The economics of biological invasions written by Charles Perrings, Silvana Dalmazzone, Mark Herbert Williamson and published by Edward Elgar Publishing. This book was released on 2000-08-25 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'An interesting book catering perhaps for a more specific audience. It does however provide a somewhat new view of the problems of the field of biological invasions and is worth the effort.' - Ann Sundqvist, M2 Best Books 'Once again, Charles Perrings and colleagues have broken new ground by applying economic and ecological analysis to the very real problem of biological invasions. This is path-breaking work in what promises to be a new sub-discipline within environmental economics.' - David Pearce, University College London, UK Biological invasions - the introduction of living organisms beyond their original range - are one of the main drivers of biodiversity loss. They are a major threat to human health and a source of pests and pathogens in the world's farms, forests and fisheries. The growth of international trade and travel means that more species are being introduced to more places than ever before. This book represents the first concerted effort to understand the economic causes and consequences of biological invasions. The volume discusses the theoretical and methodological issues raised by invasion, including control strategies, modelling options, and a study of the economic, institutional and policy conditions that predispose countries to biological invasions. Also included are case studies of fisheries, agricultural systems, tropical forests and protected areas affected by invasive species in locations such as the Black Sea, Australia and Africa, and an evaluation of control programmes.
Download or read book Nature Out of Place written by Jason Van Driesche and published by Island Press. This book was released on 2013-04-10 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though the forests are still green and the lakes full of water, an unending stream of invasions is changing many ecosystems around the world from productive, tightly integrated webs of native species to loose assemblages of stressed native species and aggressive invaders. The earth is becoming what author David Quammen has called a "planet of weeds." Nature Out of Place brings this devastating but overlooked crisis to the forefront of public consciousness by offering a fascinating exploration of its causes and consequences, along with a thoughtful and practical consideration of what can be done about it. The father and son team of Jason and Roy Van Driesche offer a unique combination of narratives that highlight specific locations and problems along with comprehensive explanations of the underlying scientific and policy issues. Chapters examine Hawaii, where introduced feral pigs are destroying the islands' native forests; zebra mussel invasion in the rivers of Ohio; the decades-long effort to eradicate an invasive weed on the Great Plains; and a story about the restoration of both ecological and human history in an urban natural area. In-depth background chapters explain topics ranging from how ecosystems become diverse, to the characteristics of effective invaders, to procedures and policies that can help prevent future invasions. The book ends with a number of specific suggestions for ways that individuals can help reduce the impacts of invasive species, and offers resources for further information. By bringing the problem of invasive species to life for readers at all levels, Nature Out of Place will play an essential role in the vital effort to raise public awareness of this ongoing ecological crisis.

Available in PDF, EPUB and Kindle. Book excerpt: It argues that it is the trade-off between the irregular, chaotic dynamics at the population level and the spatio-temporal organization of the system as a whole, that shapes ecological systems. Such a trade-off is mediated by the effects of positive feedback that link populations across time and space.
