Winner of the Marsh Book of the Year Award (2015) Throughout British history rivers have been of profound economic, social and cultural importance - yet as we see with increasing frequency they have the potential to wreak great destruction. This book describes the natural and not-so-natural changes that have affected British rivers since the last ice age and looks at the many plants and animals that live along, above and within them. Detailed case studies of the Meon, Dee and Endrick illustrate the incredibly varied nature of our river ecosystems, and the natural and human factors that make each one different. Written by two widely respected river ecologists, the book looks not only at rivers as they were and are but also at how they can be managed and cared for. Full of interesting facts and stunning images, Rivers is essential reading for anyone professionally involved in rivers and for the naturalist, conservationist and layman alike. It is the one book you need to understand this singularly important and often contentious feature of the British landscape.

Ponds and pools are a common feature of our landscape – there are at least ten times as many ponds as lakes in the UK – and they are also important wildlife habitats. This book provides a comprehensive and detailed account of these freshwater habitats. The first chapter discusses what ponds, pools and puddles are, how they differ from rivers and lakes, their origin – natural or man-made, the different types of ponds and their abundance and distribution in Britain. A second chapter looks at ponds as ancient natural habitats that have existed for millennia on the earth’s surface. Ancient pond communities, as preserved in inter- and post-glacial sediments, are compared with modern pond communities. This chapter also examines the physical and chemical environment of ponds, covering aspects such as size, shape and depth, hydrology, oxygen and temperature. Ponds, pools and puddles are important wildlife habitats; they are as rich in species as rivers, and support rare and uncommon taxa including about half of Britain’s Red Data Book wetland plant and animal species. The authors give a comprehensive survey of the variety of plant and animal life for which ponds, pools and puddles are a habitat, with a chapter each on plants, invertebrates, amphibians, and fish, birds and mammals. The book discusses the importance of ponds to each of these groups and the ways in which the organisms exploit ponds, describing their habitats and major variations in life cycles. The pond ecosystem and colonisation and succession are discussed in two further chapters, before the final chapter, which is devoted to the subject of conservation and how best to protect and manage ponds and pond wildlife in Britain today. In spite of their evident importance, ponds have been largely ignored by freshwater biologists during this century. Ponds, Pools and Puddles makes an invaluable contribution to raising awareness of these popular, yet frequently underrated freshwater habitats, giving them the attention they rightly deserve.

R4,204 Discovery Miles 42 040 Ships in 12 - 17 working days

This new volume addresses the environmental impacts of pollution on freshwater aquatic ecosystems and presents sustainable management and remediation practices and advanced technology help to address the different types of pollutants. Freshwater Pollution and Aquatic Ecosystems: Environmental Impact and Sustainable Management considers the need for sustainable, efficient, and cost-effective tools and technologies to assess, monitor, and properly manage the increasing issues of aquatic pollution. It provides detailed accounts of the phenomena and mechanisms related to aquatic pollution and highlights the problems and threats associated with pollution contamination in freshwater. It provides useful insight into the sustainable and advanced pollution remediation technology adopted by different countries for the monitoring, assessment, and sustainable management of pollution. The chapters in the volume evaluate the sources of harmful pollutants, which include industrial effluents, sewage, and runoff from agricultural industries, which result in toxic microbes, organic waste, oils, and high load of nutrients. Unsustainable management practices of domestic sewage and indiscriminate use of chemical pesticides lead to the technological disturbance of aquatic biota. In addition to harming aquatic biota, these pollutants find their way into the human body through inhalation, ingestion, or absorption and finally tend to bio-accumulate in trophic levels of the food chain, which poses a major risk to human beings. This book will be a valuable resource for ecologists, environmentalists, scientists, and many others for their work in understanding and management of aquatic pollutants in freshwater biospheres.

R5,716 Discovery Miles 57 160 Ships in 12 - 17 working days

Even a cursory perusal of any analytical journal will demonstrate the increasing important of trace and ultra-trace analysis. And as instrumentation continues to develop, the definition of the term "trace element" will undoubtedly continue to change. Covering the composition and underlying properties of freshwater and marine systems, Analytical Measurements in Aquatic Environments provides the basis for understanding both. It discusses all aspects of analytical protocols from the handling of representative samples to the metrological evaluation of specific steps and whole procedures. The book covers: handling of representative samples sample preservation techniques extraction techniques speciation analytics solvent-free sample preparation for analysis application of biotests bioanalytical methods for monitoring green analytical chemistry-application of the concept of sustainability in analytical laboratories application of the Life Cycle Assessment approach quality control and quality assurance of analytical results enhanced techniques of sample preparation hyphenated analytical techniques Ecotoxicological considerations and the effort to achieve an increasingly accurate description of the state of the environment challenge analytical chemists who need to determine increasingly lower concentrations of various analytes in samples that have complex and even non-homogenous matrices. The newly coined expression "analytics" emphasizes the interdisciplinary nature of available methods for obtaining information about material systems, with many methods that exceed the strict definition of analytical chemistry. Drawing on the disciplines of chemistry, physics, computer science, electronics, material science, and chemometrics, this book provides in depth information on the most important problems in analytics of samples from aquatic ecosystems.

The Algal Bowl - Overfertilization of the World's Freshwaters and Estuaries (Paperback): David W. Schindler The Algal Bowl - Overfertilization of the World's Freshwaters and Estuaries (Paperback)
David W. Schindler
R1,239 Discovery Miles 12 390 Ships in 12 - 17 working days

In 1974, John R. Vallentyne predicted that by the year 2000 we would be living in an environmental disaster he called the Algal Bowl. Just as the Dust Bowl of the 1930s was created by misusing western farmland, he forecast that the continuing miuse of lakes could only lead to water degradation. In the first edition of The Algal Bowl: Lakes and Man, he explained how the biology of lakes is changed by an overload of nutrients - a process known as eutrophication. Vallentyne demonstrated that human activity was the primary cause of eutrophicationand therefore responsible for the explosive growth of algae. His efforts helped move policy makers in North America to action regarding the dangers of phosphates in fresh water. Witnessing the escalation of eutrophication, Vallentyne invited his colleague, David W. Schindler, to substantially revise this groundbreaking book. Along with updates to the scientific data, Schindler added five chapters of new research, including the effect of eutrophication on ocean estuaries. Two of North America's leading water scientists joined forces to explain the science and strategies that are essential to understanding and protecting whole water systems from eutrophication and massive algae blooms. Scientists, opinion leaders, policy makers, and concerned citizens will find this fully revised and expanded second edition an unambiguous diagnosis and prescription for change.

R3,928 Discovery Miles 39 280 Ships in 12 - 17 working days

Freshwater ecosystems have the greatest species diversity per unit area and many endangered species. This book shows that, rather than being a marginal part of terrestrial protected area management, freshwater conservation is central to sustaining biodiversity. It focuses on better practices for conserving inland aquatic ecosystems in protected areas, including rivers, wetlands, peatlands, other freshwater and brackish ecosystems, and estuaries. The authors define inland aquatic ecosystems, showing just how diverse and widespread they are. They examine the principles and processes that are essential for the conservation of freshwater ecosystems and aquatic species. Major categories of threats to freshwater ecosystems and the flow-on implications for protected area design are described. Practical case studies are used to illustrate principles and practices applied around the world. Specific management needs of the main types of freshwater ecosystems are considered, as well as the management of freshwaters in the broader landscape, showing how natural resource governance processes can be harnessed to better manage freshwater biodiversity. The book offers commentary on how to adapt freshwater conservation practices to climate change and ends with an insightful synthesis.
