Book excerpt: "Situated on the western margin of Europe, Wales has been moulded by the erosional and depositional power of its fresh waters by virtue of high rainfall interacting with extensive regions of bedrock and post- Ice Age glacial debris. The result is a still evolving landscape rich in upland bogs, springs, mountain streams and lakes, rivers running through deeply eroded valleys, and large, lowland rivers meandering across wide floodplains into estuaries and the sea. Subsequent chapters bring together, for the first time, the combined expertise of a group of scientists whose intimate and collective knowledge of the Welsh aquatic landscape is unparalleled. The authors begin by describing the knowledge base of these important habitats, emphasising the structure and role of their plant, animal, and microbial communities. Upon this are built chapters that review the pioneering role of Welsh river studies in the development of running water science and, very poignantly, assess the high degree of human alteration of the principality's riverine ecosystems. These are followed by chapters that discuss the need for further scientific study, management, conservation, restoration and education so that future impacts on Welsh waters may be understood and minimised. Throughout the book flows the underlying theme that there has been and always will be a close link between water resources and the development of Welsh society."--Publisher's description.

Download or read book The European Nitrogen Assessment written by Mark A. Sutton and published by Cambridge University Press. This book was released on 2011-04-14 with total page 665 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting the first continental-scale assessment of reactive nitrogen in the environment, this book sets the related environmental problems in context by providing a multidisciplinary introduction to the nitrogen cycle processes. Issues of upscaling from farm plot and city to national and continental scales are addressed in detail with emphasis on opportunities for better management at local to global levels. The five key societal threats posed by reactive nitrogen are assessed, providing a framework for joined-up management of the nitrogen cycle in Europe, including the first cost-benefit analysis for different reactive nitrogen forms and future scenarios. Incorporating comprehensive maps, a handy technical synopsis and a summary for policy makers, this landmark volume is an essential reference for academic researchers across a wide range of disciplines, as well as stakeholders and policy makers. It is also a valuable tool in communicating the key environmental issues and future challenges to the wider public.

This book was released on 2016-12-05 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seaside has always held a special position in British history as a place of rest, relaxation and recuperation. Over the last 200 years many have made their way to the coast, attracted by the long sunshine hours, the clean ozone-charged air and the opportunities for bathing in and even drinking sea-water. Although the early health resort ideal began to give way to more pleasure orientated themes in the nineteenth century, the seaside holiday was still regarded by many as a wholesome and invigorating break from inland urban life well into the twentieth century. Yet with ever increasing numbers of visitors and rising levels of coastal pollution, this was by no means a forgone conclusion. The Seaside, Health and the Environment in England and Wales since 1800 explores the ways in which English seaside resorts continually reinvented themselves to take account of contemporary trends in popular leisure and maintain their hold on the public's imagination. Particular account is paid to the interwar years when new obsessions with outdoor activities such as sunbathing and tanning were purposefully adopted by the industry to define the modern image of the resort holiday. For these and other reasons the seaside holiday reached new peaks of popularity in the 1930s and 1950s, yet, this very success placed enormous pressures on the environmental amenities that people came to enjoy. As this work shows, environmental stresses were manifold, particularly pollution of the resorts' prime assets, their beaches. As such, serious questions are raised concerning why it took such a long time for a determined effort to be made to reverse beach pollution, and the lessons to be learned regarding the impact of negative images of the coast as a zone of danger and infection.

This book was released on 2018-08-23 with total page 767 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace metals play key roles in life - all are toxic above a threshold bioavailability, yet many are essential to metabolism at lower doses. It is important to appreciate the natural history of an organism in order to understand the interaction between its biology and trace metals. The countryside and indeed the natural history of the British Isles are littered with the effects of metals, mostly via historical mining and subsequent industrial development. This fascinating story encompasses history, economics, geography, geology, chemistry, biochemistry, physiology, ecology, ecotoxicology and above all natural history. Examples abound of interactions between organisms and metals in the terrestrial, freshwater, estuarine, coastal and oceanic environments in and around the British Isles. Many of these interactions have nothing to do with metal pollution. All organisms are affected from bacteria, plants and invertebrates to charismatic species such as seals, dolphins, whales and seabirds. All have a tale to tell.
Download or read book Where River Meets Sea written by Lynne Turner and published by CSIRO PUBLISHING. This book was released on 2006-03-17 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuaries are dynamic coastal waterways where salt and fresh water mix. Where River Meets Sea describes the value and status of Australia's 974 estuaries and takes readers on a state-by-state tour describing the health, geography, science, management and ecological functions of these unique coastal waterways. It includes profiles of people and their relationships with estuaries. The book's many photographs, maps, case studies and diagrams will help Australians to better understand, appreciate and wisely use these natural areas. Chapters on natural history, coastal science and management give an understanding of our vast network of pristine and heavily modified estuaries – from isolated tide-dominated estuaries in Australia's tropical north to those shaped by waves in southern, temperate waters. Other chapters show how people use and value coastal catchments and waterways, the impacts of human development on natural ecosystems, and how estuaries can be better managed in future. Where River Meets Sea aims to provide Australians with a deeper appreciation of our coastal waterways that are both vital for our economy and precious to our quality of life. This is a re-issued version of the original work published by the CRC for Coastal Zone Estuary and Waterway Management in 2004,
Download or read book Australian Saltmarsh Ecology written by Neil Saintilan and published by CSIRO PUBLISHING. This book was released on 2009-02-11 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australian Saltmarsh Ecology presents the first comprehensive review of the ecology and management of Australian saltmarshes. The past 10 years in particular have seen a sustained research effort into this previously poorly understood and neglected resource. Leading experts in the field outline what is known of the biogeography and geomorphology of Australian saltmarshes, their fish and invertebrate ecology, the use of Australian saltmarshes by birds and insectivorous bats, and the particular challenges of management, including the control of mosquito pests, and the issue of sea-level rise. They provide a powerful argument that coastal saltmarsh is a unique and critical habitat vulnerable to the combined impacts of coastal development and sea-level rise. The book will be an important reference for saltmarsh researchers, marine and aquatic biologists, natural resource managers, environmentalists and ecologists, as well as undergraduate students and the interested layperson.
Download or read book Ecology of Salmonids in Estuaries around the World written by Colin D. Levings and published by UBC Press. This book was released on 2016-05-15 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: For centuries, biologists have marvelled at how anadromous salmonids – fish that pass from rivers into oceans and back again – survive as they migrate between these two very different environments. Yet, relatively little is understood about what happens to salmonid species (including salmon, steelhead, char, and trout) in the estuaries where they make this transition from fresh to salt water. This book explains the critical role estuaries play in salmonid survival. Ecology of Salmonids in Estuaries around the World synthesizes information from a vast array of literature, to describe the specific adaptation of eighteen anadromous salmonids in four genera (Hucho, Oncorhynchus, Salmo, and Salvelinus) explain the ecological relationships between anadromous salmonids, the fish they coexist with, and their estuarine habitat discuss key fitness elements salmonids need for survival (including those relating to osmoregulation, growth and feeding mechanisms, and biotic interactions) provide guidance on how to conduct estuarine sampling and scientific aspects of management and recovery plans offer directions for future research. The critical reference is further enhanced by extensive supplementary appendices that are available online, including data tables, additional references on estuarine salmonids, and a primer on estuaries and salmonids for citizen scientists.
