Download or read book The Atlantic Salmon written by Eric Verspoor and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic Salmon is a cultural icon throughout its North Atlantic range; it is the focus of probably the World’s highest profile recreational fishery and is the basis for one of the World’s largest aquaculture industries. Despite this, many wild stocks of salmon are in decline and underpinning this is a dearth of information on the nature and extent of population structuring and adaptive population differentiation, and its implications for species conservation. This important new book will go a long way to rectify this situation by providing a thorough review of the genetics of Atlantic salmon. Sponsored by the European Union and the Atlantic Salmon Trust, this book comprises the work of an international team of scientists, carefully integrated and edited to provide a landmark book of vital interest to all those working with Atlantic salmon.
Download or read book Evolution of Marine Coastal Ecosystems under the Pressure of Global Changes written by Hubert-Jean Ceccaldi and published by Springer Nature. This book was released on 2020-06-15 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal and estuarine environments at the interface of terrestrial and marine areas are among the most productive in the world. However, since the beginning of the industrial era, these ecosystems have been subjected to strong anthropogenic pressures intensified from the second half of the 20th century, when there was a marked acceleration in the warming (climate change) of the continents, particularly at high latitudes. Coastal ecosystems are highly vulnerable to alteration of their physical, chemical and biological characteristics (marine intrusion, acidification of marine environments, changes in ecosystems, evolution and artificialization of the coastline, etc.).In contact with heavily populated areas, these environments are often the receptacle of a lot of chemical and biological pollution sources that significantly diminish their resilience. In this context of accelerated evolution and degradation of these areas important for food security of many populations around the world, it is necessary to better identify the factors of pressure and understand, at different scales of observation, their effects and impacts on the biodiversity and on the socio-eco-systems, in order to determine the degree of vulnerability of these coastal ecosystems and the risks they face. A transdisciplinary and integrated approach is required to prevent risks. Within this framework, operational coastal oceanography occupies an important place but also the implementation of a true socio-eco-system approach in order to set up an environmentally friendly development.
Download or read book The Atlantic Salmon written by W. M. Shearer and published by John Wiley & Sons. This book was released on 1992-10-06 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: An internationally-renowned biologist describes the life history of the Atlantic salmon in light of intensive research over the last 30 years. Provides an authoritative and detailed appraisal of the fisheries that exploit this valuable resource. The salmon's conflict with the environment is examined in the context of changes in land use, water abstraction and acidification. A complete analysis of the author's North Esk investigation is given and the effects of fish farming on wild stocks and the salmon's future are discussed.

Download or read book Integrating Ecohydraulics in River Restoration written by José Maria Santos and published by MDPI. This book was released on 2020-03-16 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers have been intensively degraded due to increasing anthropogenic impacts from a growing population in a continuously developing world. Accordingly, most rivers suffer from pressures as a result of increasing dam and weir construction, habitat degradation, flow regulation, water pollution/abstraction, and the spread of invasive species. Science-based knowledge regarding solutions to counteract the effects of river degradation, and melding principles of aquatic ecology and engineering hydraulics, is thus urgently needed to guide present and future river restoration actions. This Special Issue gathers a coherent set of studies from different geographic contexts, on fundamental and applied research regarding the integration of ecohydraulics in river restoration, ranging from field studies to laboratory experiments that can be applied to real-world challenges. It contains 13 original papers covering ecohydraulic issues such as river restoration technologies, sustainable hydropower, fish passage designs and operational criteria, and habitat modeling. All papers were reviewed by international experts in ecology, hydraulics, aquatic biology, engineering, geomorphology, and hydrology. The papers herein well represent the wide applicability of ecohydraulics in river restoration and serve as a basis to improve current knowledge and management and to reduce arguments between different interests and opinions.
Download or read book Molecular Diagnosis of Salmonid Diseases written by Carey O. Cunningham and published by Springer Science & Business Media. This book was released on 2002-02-28 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive collection of molecular techniques for diagnosing diseases important in the culture and conservation of salmonid fish. It brings together leading authors in this rapidly growing field and provides an overview of the present state of the art from the perspective of practical application of these methods in diagnostic laboratories. This book will serve as a useful handbook for diagnosticians and researchers involved in fish disease, particularly laboratories establishing these new diagnostic tests for the first time, and provides valuable background information on many of the diseases and their causative organisms.

Download or read book Groundwater Surface Water Interactions written by Habil. Jörg Lewandowski and published by MDPI. This book was released on 2020-12-10 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen a paradigm shift in our understanding of groundwater–surface water interactions: surface water and aquifers were long considered discrete, separate entities; they are now understood as integral components of a surface–subsurface continuum. This book provides an overview of current research advances and innovative approaches in groundwater–surface water interactions. The 20 research articles and 1 communication cover a wide range of thematic scopes, scales, and experimental and modelling methods across different disciplines (hydrology, aquatic ecology, biogeochemistry, and environmental pollution). The book identifies current knowledge gaps and reveals the challenges in establishing standardized measurement, observation, and assessment approaches. It includes current hot topcis with environmental and societal relevance such as eutrophication, retention of legacy, and emerging pollutants (e.g., pharmaceuticals and microplastics), urban water interfaces, and climate change impacts. The book demonstrates the relevance of processes at groundwater–surface water interfaces for (1) regional water balances and (2) quality and quantity of drinking water resources. As such, this book represents the long-awaited transfer of the above-mentioned paradigm shift in understanding of groundwater–surface water interactions from science to practice.
