Salmon at the Edge covers, in depth, the problems faced by wild Atlantic salmon and sea trout in estuaries and coastal zones, and in their early weeks at sea. The book also reflects the current precarious state of many migratory salmonid populations and the need for new approaches to a number of threats to these populations. Generated from papers given at the landmark Sixth Atlantic Salmon Symposium, held in Edinburgh, UK, Salmon at the Edge contains a huge wealth of information on such important topics as the impact of salmon farming, the behaviour of post-smolts in their early migration and their vulnerability to by-catch, and the use of nutrient enrichment and habitat enhancement to increase production of juvenile salmonids. With chapters written by internationally-known and respected authors, and including a message of support from His Royal Highness The Prince of Wales, this important volume is essential reading for all those involved with salmonid fishes, including fish biologists, fisheries scientists and managers, environmental, marine and freshwater scientists, and personnel involved in salmon aquaculture. Libraries in all universities and research establishments where these subjects are studied and taught should have copies on their shelves. The Sixth Atlantic Salmon Symposium, from which chapters in this book have been generated, was organised by The Atlantic Salmon Trust and The Atlantic Salmon Federation, and was published with the financial support of The Fishmongers’ Company and Scottish and Southern Energy. Derek Mills of The Atlantic Salmon Trust, Pitlochry, Perthshire, UK has many years of research, writing and editing experience in salmon biology and fisheries

This book brings together research into the process of stream acidification and its impact on Welsh surface waters, carried out over the past decade or so. It is perhaps surprising that not until the 1980's was clear evidence of stream acidification assembled. In Wales, concerns over pollution had focused water quality sampling principally on the areas of traditional heavy industry and large urban popula tions served by inadequate sewerage systems and sewage disposal arrange ments. Mistakenly, it had been assumed that, with its prevailing westerly winds, Wales would receive precipitation substantially unpolluted by the industrial and urban emissions from Britain and mainland Europe. Assurance of the high quality of Welsh upland streams, the traditional nursery ground of salmonids, was eroded particularly by studies in the vicinity of Llyn Brianne reservoir in the catchment of the River Tywi of Central Wales. These demonstrated a clear correspondence between the biological quality and fisheries of streams in the catchment and aspects of stream chemistry, par ticularly pH, aluminium and calcium on the one hand, and catchment land use on the other. It is salutary to record that the first signals were of an inexplicable failure of the runs of migratory salmonids into the upper catchment, occupied by the Llyn Brianne reservoir and its influent streams, and the failure to restore the fishery by re-stocking with eggs and fry. Only then did the significance of the recent decline in some other upland lake and reservoir fisheries in Wales become apparent.

Hydrology is vital to human civilisations as well as to natural ecosystems, yet it has only emerged as a distinct scientific discipline during the last 50 years or so. This book reviews the development of modern hydrology primarily through the experiences of the multidisciplinary team of scientists and engineers at Wallingford, near Oxford, who have been at the forefront of many of the developments in UK hydrological research. These topics include: • The development of basic understanding through the collection of data with specialised instrumentation in experimental basins • The study of extreme flows – both floods and droughts • The role moisture in the soil • Studies of the processes controlling evaporation • Water resource studies • Modelling and prediction of the extremes of flow improved • Understanding of water quality issues • A widening recognition of the importance of an ecosystem approach • Meeting the challenges of climate change, • Data handling • Future developments in hydrology and the pressures which generate them. Readership: hydrologists in both academia and a wide range of applied fields such as civil engineering, meteorology, geography and physics, as well as advanced students in earth science, environmental science and physical geography programmes worldwide.

This revised edition of Energy Law and the Environment considers how international and national legislation now requires the energy sector to focus more on sustainability and the circular economy in response to new policies at both international and national levels. It explores how environmental law engages with multinational companies regarding energy sources, ownership of those resources, and state sovereignty. Written for all the players in the energy sector, lawyers and non-lawyers alike, this third edition considers the issues of energy sector regulation related to economics and protection of intellectual property associated with the development of technologies for mitigating environmentally damaging emissions. It has been updated throughout and adds new and fully revised chapters on subjects, including climate change, human rights, renewable energy, and energy law in China. Features: Updated throughout and adds new and fully revised chapters Focuses on the global trends and mandates towards environmental sustainability Examines the latest international legislation involving climate change Includes the coverage of oil and gas industries, as well as nuclear and renewable energy

While existing approaches to monitoring environmental contaminants tend to focus on a small suite of contaminant types and often involve monitoring at fixed points and at fixed times, Monitoring Environmental Contaminants focuses on a wide range of new technologies and approaches available for monitoring chemical and biological contaminants in air, water, soil and food. These new methods allow the ability to monitor a wider range of contaminants at much greater and temporal resolutions. Adoption of these methods could result in a change in our understanding of how humans and ecosystems are exposed to contaminants in different environmental media. This volume in the Environmental Contaminants Series provides an overview of a wide range of monitoring approaches ranging from citizen science networks to the use of robotics and sensor networks. Monitoring Environmental Contaminants describes challenges in the adoption of some of these new approaches and methods for dealing with these challenges such as the use of mining techniques for large data. The case studies within will provide a thorough illustration for researchers, academics, and scientists involved in ecology and environmental sciences. Brings together chapters from a wide range of research in ecology and the environmental sciences Utilizes an easily understandable style that can be absorbed by a wide audience Uses case studies to illuminate the application of selected novel contamination monitoring approaches
