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 2012-03-12 with total page 918 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 Brown Trout written by Javier Lobón-Cerviá and published by John Wiley & Sons. This book was released on 2017-12-18 with total page 821 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brown Trout: Biology, Ecology and Management A comprehensive guide to the most current research, history, genetics and ecology of the brown trout including challenging environmental problems The brown trout is an iconic species across its natural European distribution and has been introduced throughout the World. Brown Trout offers a comprehensive review of the scientific information and current research on this major fish species. While the brown trout is the most sought species by anglers, its introduction to various waters around the world is causing serious environmental problems. At the same time, introduction of exogenous brown trout lineages threats conservation of native gene pools of populations in many regions. The authors summarize the important aspects of the brown trout’s life history and ecology and focus on the impact caused by the species. The text explores potential management strategies in order to maintain numerous damaged populations within its natural distributional range and to ameliorate its impacts in exotic environments. The authors include information on a wide-range of topics such as recent updates in population genetics, evolutionary history, reproductive traits and early ontogeny, life history plasticity in anadromous brown trout and life history of the adfluvial brown trout and much more. This vital resource: Contains the latest research on the biology and ecology of brown trout Includes information on phylogeography, genetics, population dynamics and stock management Spotlights the brown trout’s introduction to regions around the world and the serious environmental impacts Offers a comprehensive review of conservation and management techniques Written for salmonid scientists and researchers, fishery and environmental managers, and students of population genetics, ecology and population dynamics, Brown Trout explores the most recent findings on the history, ecology and sustainability of this much-researched species.

Download or read book Management and Ecology of Freshwater Plants written by Joseph Caffrey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical, physical, biological and biomanipulation. This series of papers from over 20 different countries was generated from the highly successful European Weed Research Society symposia on aquatic plant management, this being the ninth. The contributions provide a valuable insight into the complexities involved in managing aquatic systems, discuss state-of-the-art control techniques such as biomanipulation using fish and waterfowl and the use of straw, and deal with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants, including growth responses under different trophic conditions, the impact of pollution, and aspects of photosynthesis. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.
Download or read book Lake Restoration Handbook written by David P. Hamilton and published by Springer. This book was released on 2019-01-29 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lakes across the globe require help. The Lake Restoration Handbook: A New Zealand Perspective addresses this need through a series of chapters that draw on recent advances in modelling and monitoring tools, citizen science and First Peoples’ roles, catchment and lake-focused restoration techniques, and policy implementation. New Zealand lakes, like lakes across the globe, are subject to multiple pressures that have increased in severity and scale as land use has intensified, invasive species have spread and global climate change becomes manifest. This books builds on the popular Lake Managers Handbook (1987), which provided guidance on undertaking investigations into, and understanding lake ecosystems in New Zealand. The Lake Restoration Handbook: A New Zealand Perspective synthesises contemporary issues related to lake restoration and rehabilitation, integrated with social science and cultural viewpoints, and complemented by authoritative topic-area summaries by renowned scientists and practitioners from across the globe. The book examines the progress of lake restoration and the new and emerging tools available to managers for predicting and effecting change. The book will be a valuable resource for natural and social scientists, policy writers, lake managers, and anyone interested in the health of lake ecosystems.

Available in PDF, EPUB and Kindle. Book excerpt: The thirteen papers presented in this publication review fish stocks and fisheries of mountainous areas of Asia: Himalayas (Bhutan, Nepal, northern states of India within the Himalayas), Western Ghats (India), Karakoram-Hindu Kush (Pakistan, Afghanistan), Pamir (Tajikistan), Tien Shan (Kyrgyzstan, Kazakhstan), Altai (Kazakhstan, Mongolia, China), high altitude lakes of Mongolia and those of western China (provinces of Qinghai and Xinjiang [Uighur Autonomous Region] and Xizang [Tibet Autonomous Region]) and Caucasus (Armenia, Georgia, Azerbaijan). From south to north, fish fauna complexes change from Oriental to Palaearctic. Cool and coldwater streams and rivers support subsistence and/or recreational/sport fisheries, with commercial fisheries practised only in some lakes and reservoirs. While fishing of streams and rivers is largely unmanaged, considerable management effort has gone into some lakes and reservoirs, especially in Kazakhstan, Kyrgyzstan and India in order to maintain reasonably high fish catches. The management measures have included translocation and stocking of exotic fish species and regulation of fisheries. For recreational fishery, brown trout has been stocked in rivers and streams of the southern slopes of Himalayas, rainbow trout in some streams of Western Ghats ... etc.

The book comprises a number of general essays, exploring and challenging common perceptions about such species, and a series of case studies of specific species in specific contexts. Its geographical coverage ranges from the United Kingdom to New Zealand by way of South Africa, India and Palestine; and the essays cover both historical and recent introductions.
