Great Lakes Journey is a follow-up to William Ashworth's earlier book ""The Late, Great Lakes"", published in 1986. Fifteen years after his first trip, Ashworth journeys to many of the same places and talks to many of the same people to examine the changes that have taken place along the Great Lakes since the 1980s. It is a poetic account of his 6000-mile trip, mixed with explanations of the scientific and poilitical realities behind the observed changes, reminiscences of his 1983 trip, and conversations with local residents - some of them scientists, and other simply people who care. Through personal observations, research and numerous interviews with scientists, activists and government agencies, Ashworth creates a detailed picture of the status of the Great Lakes at the end of the 20th century. Among the most prominent changes he finds are the arrival of the zebra mussel and other exotic species, the rise and fall of the RAP process for pollution cleanup, a growing public mistrust of government action, a substantial loss of habitat and biodiversity, and an explosion of urban sprawl along the shores of the Lakes. Scholars and students of environmental studies and ecology and readers interested in the health of the Great Lakes should find this fresh look at one of America's endangered regions of value.

River systems involve a complex interaction of a rich diversity of microorganisms, plants and animals with their physical and chemical environment. Uniquely, the river habitat presents particular problems for organisms exposed to unidirectional currents, seasonal variation in flow, and disturbance due to pollution and other human interference. Drawing on chapters from the two volumes of The Rivers Handbook, this book describes river organisms - the taxa, their adaptations and ecologies, and their trophic interactions. After considering the principles, practice and problems associated with making reliable observations on river organisms, the final chapters investigate how river biota are impacted by human activity, and how in turn they can be used as indicators of these effects in river management. Aimed at final-year undergraduate and postgraduate students, the book will also be of interest to all those concerned with river conservation, including environmental scientists, river engineers and river managers.

The poor quality of water, as well as its restricted supply and availability, is one of the biggest challenges of our time, with presently two-fifth's of the world's population unable to find adequate fresh water for essential usage. Over 40 years' research has been carried out on the positive effects that rhythms and specific water flow has on water's capacity to support life. Energizing Water presents this cutting-edge research to the general and professional reader at a time when interest in finding solutions to water's huge worldwide problems is growing rapidly. Three aspects determine water quality: its chemical constituents (including its oxygen levels); its organic aspects (with the danger of contamination by effluent, pathogens and algae); and its 'energetic' nature. The latter facet has been recognized from time immemorial by traditional societies, who have developed their own sciences in relation to water quality, using terms such as prana and chi for energy. Now, through the introduction of quantum physics into the life sciences, modern science is beginning to accept this concept, measuring energy as light emission. Research into energetic water quality - and particularly into the creation of moulded surfaces that support biological purification of the chemical and organic elements, as well as enlivening the energetic attributes - goes back to George Adams' and John Wilkes' pioneering work in the 1960s. The invention of Flowform technology in 1970 carried this research further, providing the world with one of the first modern-day, biomimicry eco-technologies. This creative technology applies nature's best methods to produce extraordinary results, and this book outlines the background story on research and application of the Flowform method today.

"Freshwater Marshes "was first published in 1994. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.

Prairie potholes, wetland edges of lakes and rivers, and other freshwater marshes play a vital role in maintaining a clean and plentiful water supply for wildlife and human use. These wetland areas provide habitat for spawning fish, feed waterfowl, purify and retain water, and control erosion. In this updated third edition, Milton W. Weller describes the components of the freshwater marsh: its annual and seasonal dynamics as affected by rainfall cycles and the plant and animal population's response to such changes. Weller discusses how such wetland areas are managed for wildlife populations and diversity, and how such processes can be used in wetland conservation and restoration. He considers the impact society has on wetlands and offers conservation goals for freshwater wetland complexes. Weller broadens the third edition to include an analysis of how prairie wetlands compare in water dynamics with swamps, tidal marshes, and other wetlands. He also expands the discussion of wetland classification, evaluation, mitigation, and restoration, and introduces a new glossary of current wetland terminology.

"Freshwater Marshes " is Volume 1 of Wildlife Habitats.

Milton W. Weller is professor emeritus and former Kleberg Chair in Wildlife Ecology, at Texas A&M University.

The Late, Great Lakes is a powerful indictment of man's carelessness, ignorance, and apathy toward the Great Lakes. With the longest continuous coastline in the United States, they hold one-fifth of the world's freshwater supply. Author William Ashworth presents a compelling history of the Great Lakes, from their formation in the Ice Age, to their "discovery" by Samuel de Champlian in 1615, and, finally, to their impending death in our time. Ashworth systematically deals with the wild life that once flourished in the region-beaver, salmon, whitefish, and trout-and describes the threatening elements which have displaced them-the predatory sea lamprey, the alewives, toxic waste, and volatile solids.

Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

This Second Edition of Plankton is a fully updated introduction to the biology, ecology and identification of plankton and their use in monitoring water quality. It includes expanded, illustrated descriptions of all major groups of freshwater, coastal and marine phytoplankton and zooplankton and a new chapter on teaching science using plankton. Best practice methods for plankton sampling and monitoring programs are presented using case studies, along with explanations of how to analyse and interpret sampling data. Healthy waterways and oceans are essential for our increasingly urbanised world. Yet monitoring water quality in aquatic environments is a challenge, as it varies from hour to hour due to stormwater and currents. Being at the base of the aquatic food web and present in huge numbers, plankton are strongly influenced by changes in environment and provide an indication of water quality integrated over days and weeks. Plankton are the aquatic version of a canary in a coal mine. They are also vital for our existence, providing not only food for fish, seabirds, seals and sharks, but producing oxygen, cycling nutrients, processing pollutants, and removing carbon dioxide from our atmosphere. This new edition: contains a new chapter on Plankton in the Classroom has greatly expanded coverage of coastal and marine phytoplankton explains the role of plankton in aquatic ecosystems and its usefulness as a water quality indicator updates and details best practice in methodology for plankton sampling and monitoring programs brings together widely-scattered information on freshwater and coastal phytoplankton and zooplankton and provides a list of up-to-date references. Plankton is an invaluable reference for teachers and students, environmental managers, ecologists, estuary and catchment management committees, and coastal engineers.

Pearly mussels (Unionoidea) live in lakes, rivers, and streams around the world. These bivalves play important roles in freshwater ecosystems and were once both culturally and economically valuable as sources of food, pearls, and mother-of-pearl. Today, however, hundreds of species of these mussels are extinct or endangered. David L. Strayer provides a critical synthesis of the factors that control the distribution and abundance of pearly mussels. Using empirical analyses and models, he assesses the effects of dispersal, habitat quality, availability of fish hosts, adequate food, predators, and parasites. He also addresses conservation issues that apply to other inhabitants of fresh waters around the globe and other pressing issues in contemporary ecology.

Pollutant Effects in Freshwater provides a practical and concise introduction to the ecological consequences of water pollution in aquatic ecosystems. In tackling the problem of water quality deterioration, this book combines the limnological and water pollution literature to describe how pollutants in wastewater affect populations of organisms in freshwater environments. Substantially revised, updated and expanded, with additional specialist contributors, this retitled new edition of Ecological Effects of Wastewater will continue to focus on the effects and management of eutrophication, water quality standards to protect aquatic life, and widen the debate over micro organisms and their public health significance in the aquatic environment. With ever tighter controls on pollution levels of freshwater bodies being implemented and enforced world wide, this book is essential reading for students of public health and environmental engineering, and a reference tool for professionals in consultancies, contractors and for those in regulatory and enforcement bodies.

Freshwater ecosystems are under increasing pressure as human populations grow and the need for clean water intensifies. The demand for ecologists and environmental managers who are trained in basic freshwater ecology has never been greater. Students and practitioners new to the field of freshwater ecology and management need a text that provides them with an accessible introduction to the key questions while still providing sufficient background on basic scientific methods.

Gerry Closs, Barbara Downes and Andrew Boulton have written a text that meets the requirements of these students. Following an introduction to scientific methodology and its application to the study of ecology, several key concepts in freshwater ecology are reviewed using a wide range of scientific studies into fundamental and applied ecological questions. Key ecological questions that are explored in a freshwater context include the role of animal dispersal and predators on freshwater community structure and the impact of pollutants and introduced species on freshwater ecosystems.

This book represents the only freshwater ecology textbook that is specifically aimed at an introductory level. It will also be a useful primer for students who have not previously taken a specialized freshwater course but who require an accessible overview of the subject.
General reviews on the methods of science, influence of scale, and the main features of freshwater systems.
Coverage of several fundamental and applied ecological questions.
A logical structure in each chapter that builds from a general observation of an ecological pattern, to an exploration of the various scientific approaches that can be used to investigate such patterns.
Suggested further reading lists for each chapter.

Water is a key driver of economic and social development while it also has a basic function in maintaining the integrity of the natural environment. Presents the rationale approach for the Integrated Water Resources Management; this volume brings together both the different environmental problems that affect the very different ecosystems and the main methodologies able to face the problem of IWM. It will be of an invaluable resource for those involved in urban water management, including water utility managers, engineering technical staff, operations and maintenance specialists.

Water resources and services are integrated measures of social systems that range beyond the technical world and the IWRM requires a balance between competing views of social and political issues. This volume focuses on increased awareness of the human dimension, women's role, environmental protection, sustainability and food security aspects in achieving sustainable water management. Understanding the strategies used by small farmers, as well as how small farming systems work or why they fail, could shed light on the constraints they face and the measures to be taken to overcome them. It also draws key insights on movements promoting the involvement of grassroots communities in the sustainable management of their resources.

"The 1995 discovery of malformed frogs in a Minnesota wetland is one of a few singular events in the history of environmental awareness that has forever changed our views regarding the plight of global biodiversity. Lannoo's book offers a comprehensive and up-to-date assessment of the malformed frog phenomenon and its likely causes, as well as its possible relation to environmentally mediated malformations in humans. It immediately ranks as a definitive source for information regarding malformed frogs in the larger context of global amphibian declines."--James Hanken, Alexander Agassiz Professor of Zoology, Curator in Herpetology, and Director, Museum of Comparative Zoology, Harvard University
"Lannoo's book is unequivocally the definitive work on frog malformations, with broad relevance to the global decline of amphibians, the degradation of natural wetlands, and our own environmental legacy. This scholarly presentation by a top-rate scientist focuses on an irrefutable phenomenon in which frogs are serving as sentinels to which all of society should be listening."--J. Whitfield Gibbons, Odum School of Ecology, University of Georgia
""Malformed Frogs" is a scientific detective story with a moral: things aren't often what they seem! Mike Lannoo's engaging prose captures the joys and drudgery of fieldwork as well as the fallible, human side of science, all in the service of understanding the occurrence of deformed amphibians. He convincingly shows that although not one of the commonly advanced explanations can suffice, we know enough right now to solve the problem."--Harry W. Greene, Department of Ecology and Evolutionary Biology, Cornell University

The second edition of Stream Ecology: Structure and Function Of Running Waters is thoroughly updated and expanded, reflecting the enormous growth in our understanding of stream metabolism and nutrient processes, which are the core of ecosystem functioning. The broad diversity of running waters - from torrential mountain brooks, to large lowland rivers, to great river systems whose basins occupy subcontinents - makes river ecosystems appear overwhelmingly complex. A central theme of this book is that although the settings are often unique, the processes at work in running waters can be understood in general terms. The new edition is extensively rewritten, with hydrology and geomorphology now accorded chapter-length discussion. Coverage includes a considerably improved and updated treatment of abiotic factors, organized around the habitat template concept. Additional new material outlines important advances in microbial ecology.

Cyprinids rank as one of the most commercially important groups of freshwater fishes and are exploited for many purposes; as a human food source, especially in Europe and Asia; as sport fish; and as ornamental fish for ponds and aquaria. Certain species are also cultured as bait fish and several of the small cyprinids such as the zebra fish have become internationally accepted laboratory models for toxicology testing and molecular research. A thorough understanding of cyprinid health and diseases is fundamental to the successful management and exploitation of these fishes for freshwater fisheries, pisciculture and ornamental productions.

This practical guide to disease diagnosis, prevention and control includes numerous colour plates and covers a comprehensive array of diseases - infectious and non-infectious - of cultivated and wild cyprinids.

This text explores the spatial variation and seasonality in growth and reproduction of "Enhalus acoroides" (L.f.) Royle populations in the coastal waters off Cape Bolinao, NW Phillipines.

Designed specifically for the amateur naturalist and filled with hands-on projects and activities, Pond and Brook introduces the readers to the intriguing world of freshwater life. Michael Caduto's keen eye investigates all common freshwater environments, from wetlands and deep lakes to streams and vernal ponds. An important feature of the book is its holistic approach to both living and non-living components of freshwater environments, and how they fit together to weave an ecological whole. Readers will learn the unique properties of water, the basic principles vital to understanding aquatic life, and the origin of freshwater habitats.

The Marcell Experimental Forest (MEF) in Minnesota serves as a living laboratory and provides scientists with a fundamental understanding of peatland hydrology, acid rain impacts, nutrient and carbon cycling, trace gas emissions, and controls on mercury transport in boreal watersheds. Its important role in scientific research continues to grow as the data gathered offers invaluable insight into environmental changes over the last century and goes far in answering many of today's pressing questions at landscape and global scales. Synthesizing five decades of research, Peatland Biogeochemistry and Watershed Hydrology at the Marcell Experimental Forest includes hundreds of research publications, dozens of graduate theses, and even some previously unpublished studies. Research at the MEF has been at the forefront of many scientific disciplines and these 15 chapters offer the depth and breadth of long-term studies on hydrology, biogeochemistry, ecology, and forest management on peatland watersheds at the MEF. Focusing on peatlands, lakes, and upland landscapes, the book begins with the pioneering research on hydrology done during the 1960s. It presents the innovative 1970's studies of atmospheric deposition; the 1980's research into nutrient cycles including carbon, nitrogen, and methane emissions; and the 1990's investigations into mercury deposition. The book concludes with a look at the latest and on-going studies such as this century's research into controls on methylmercury production and landscape-level carbon storage and cycling. Covering 50 years of research and written by a veritable who's who in peatland and forestry science, this important milestone in the collection of ecological data highlights bright prospects for future research, including the continuation of existing long-term measurements, the initiation of new monitoring programs, and plans for unprecedented studies on climate change.
