An easy-to-read, beautifully illustrated undergraduate-level introduction to fresh- and running-water biology. Each chapter includes practical information on simple studies and experiments for students to try. The text begins with the physical features that define running water (lotic) habitats then continues with organisms that inhabit these habitats, and concludes with a discussion of applied issues surrounding water use, including pollution, species diversity, and conservation. The authors outline the range of living organisms in lotic habitats, and the environmental adaptations they exhibit. They discuss population, community, and ecosystem patterns and processes, such as energy flow, nutrient cycling, migration, food webs, and community structure. Particular consideration is given to links between stream and river channels and their surrounding landscapes, to short-term and seasonal changes, and to historical and biogeographical factors. The text concludes with a section of additional practical field work activities and a list for further reading.

Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. First synthetic account of the ecology of all types of tropical streams Covers all of the major tropical regions Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems Threats faced by tropical stream ecosystems and possible conservation actions Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)

California Rivers and Streams provides a clear and informative overview of the physical and biological processes that shape California's rivers and watersheds. Jeffrey Mount introduces relevant basic principles of hydrology and geomorphology and applies them to an understanding of the differences in character of the state's many rivers. He then builds on this foundation by evaluating the impact on waterways of different land use practices—logging, mining, agriculture, flood control, urbanization, and water supply development. Water may be one of California's most valuable resources, but it is far from being one we control. In spite of channels, levees, lines and dams, the state's rivers still frequently flood, with devastating results. Almost all the rivers in California are dammed or diverted; with the booming population, there will be pressure for more intervention. Mount argues that Californians know little about how their rivers work and, more importantly, how and why land-use practices impact rivers. The forceful reconfiguration and redistribution of the rivers has already brought the state to a critical crossroads. California Rivers and Streams forces us to reevaluate our use of the state's rivers and offers a foundation for participating in the heated debates about their future.

Glimpses of Creatures in Their Physical Worlds offers an eye-opening look into how the characteristics of the physical world drive the designs of animals and plants. These characteristics impose limits but also create remarkable and subtle opportunities for the functional biology of organisms. In particular, Steven Vogel examines the size and scale, and trade-offs among different physical processes. He pays attention to how the forms and activities of animals and plants reflect the materials available to nature, and he explores the unique constraints and possibilities provided by fluid flow, structural design, and environmental forces. Each chapter of the book investigates a facet of the physical world, including the drag on small projectiles; the importance of diffusion and convection; the size-dependence of acceleration; the storage, conduction, and dissipation of heat; the relationship among pressure, flow, and choice in biological pumps; and how elongate structures tune their relative twistiness and bendiness. Vogel considers design-determining factors all too commonly ignored, and builds a bridge between the world described by physics books and the reality experienced by all creatures. Glimpses of Creatures in Their Physical Worlds contains a wealth of accessible information related to functional biology, and requires little more than a basic background in secondary-school science and mathematics. Drawing examples from creatures of land, air, and water, the book demonstrates the many uses of biological diversity and how physical forces impact biological organisms.

From the Forest to the Sea: The Ecology of Wood in Streams, Rivers, Estuaries and Oceans is a fascinating new scientific work that discusses the role wood plays in very complex and diverse aquatic ecosystems. Until now almost nothing has been published on this little understood topic. 1. Wood in streams and rivers is a source of food energy for invertebrate organisms; habitat for vertebrate organisms, such as fish; and a structural component that shapes, diversifies, and stabilizes channels while helping to dissipate the water's energy before it can scour channels. 2. Wood in estuaries is a major source of food and habitat for obligatory, wood boring, marine invertebrates that in their feeding , break it down and pass usable carbon into the water's current where it enters the detrital based marine food web. 3. Wood along the coastline stabilizes sand spits, beaches, and dune complexes, as well as battering rocky shores where it creates new habitats for intertidal organisms and provides small splinters of wood to the coastal food chain. 4. Driftwood floating in the open ocean attracts a variety of marine invertebrates and fishes, forming a floating surface community that help organisms colonize new areas. Large fishes, such as tuna, not only feed on smaller fishes attracted to the wood but also drift with it because its movement is controlled by wind and current; thus tuna find the best feeding areas-current interfaces rich in food species. 5. A common textbook perception on marine biology is that, while communities of bacteria can use sulfur compounds as energy and animals can and do live around deep-sea hydrothermal vents through which hot water issues in the ocean's floor, the rest of the oceans bottom is almost devoid of life. But as driftwood becomes waterlogged and sinks, it represents terrestrially-fixed carbon in the energy poor deep-sea where at least three species of wood-borers convert it into a readily available source of detritus that in turn supports the development of complex communities of bottom-dwelling organisms. 6. The loss of wood to aquatic ecosystems means destabilization of streams, estuaries, dunes and beaches as well as food chains in the oceans of the world. Sooner or later it may mean the loss of jobs and unique cultural ways of life such as the commercial fishing of certain species.

From a mountain top where an eagle carries a salmon carcass to feed its young to the oceanic waters of the California current and the Alaskan Gyre, salmon have penetrated the Northwest to an extent unmatched by other animals. Since the turn of the twentieth century, natural productivity of salmon in Oregon, Washington, California, and Idaho has declined 80 percent. The decline of Pacific salmon to the brink of extinction is a sign of serious problems in the region. In Salmon Without Rivers, fisheries biologist Jim Lichatowich offers an eye-opening look at the roots and evolution of the salmon crisis in the Pacific Northwest. He describes the multitude of factors over the past century and a half that have led to the salmon's decline, and examines the failure of restoration efforts that have focused almost exclusively on hatcheries to return salmon stocks to healthy levels without addressing underlying causes of the decline. Lichatowich argues that the dominant worldview of our society -- a worldview that denies connections between humans and the natural world -- has created the conflict that characterizes the recent history of salmon; unless that worldview is challenged, there is little hope for recovery. Salmon Without Rivers exposes the myths that have guided recent human-salmon interactions. It explains the difficult choices facing citizens of the region, and provides unique insight into one of the most tragic chapters in our nation's environmental history.

It is zero hour for a new US water policy! At a time when many countries are adopting new national approaches to water management, the United States still has no cohesive federal policy, and water-related authorities are dispersed across more than 30 agencies. Here, at last, is a vision for what we as a nation need to do to manage our most vital resource. In this book, leading thinkers at world-class water research institution the Pacific Institute present clear and readable analysis and recommendations for a new federal water policy to confront our national and global challenges at a critical time. What exactly is at stake? In the 21st century, pressures on water resources in the United States are growing and conflicts among water users are worsening. Communities continue to struggle to meet water quality standards and to ensure that safe drinking water is available for all. And new challenges are arising as climate change and extreme events worsen, new water quality threats materialize, and financial constraints grow. Yet the United States has not stepped up with adequate leadership to address these problems. The inability of national policymakers to safeguard our water makes the United States increasingly vulnerable to serious disruptions of something most of us take for granted: affordable, reliable, and safe water. This book provides an independent assessment of water issues and water management in the United States, addressing emerging and persistent water challenges from the perspectives of science, public policy, environmental justice, economics, and law. With fascinating case studies and first-person accounts of what helps and hinders good water management, this is a clear-eyed look at what we need for a 21st century U.S. water policy.

As the vast expanses of natural forests and the great populations of salmonids are harvested to support a rapidly expanding human population, the need to understand streams as ecological systems and to manage them effectively becomes increasingly urgent. The unfortunate legacy of such natural resource exploitation is well documented. For several decades the Pacific coastal ecoregion of North America has served as a natural laboratory for scientific and managerial advancements in stream ecology, and much has been learned about how to better integrate ecological processes and characteristics with a human-dominated environment. These in sightful but hard-learned ecological and social lessons are the subject of this book. Integrating land and rivers as interactive components of ecosystems and watersheds has provided the ecological sciences with impor tant theoretical foundations. Even though scientific disciplines have begun to integrate land-based processes with streams and rivers, the institutions and processes charged with managing these systems have not done so successfully. As a result, many of the watersheds of the Pacific coastal ecoregion no longer support natural settings for environmental processes or the valuable natural resources those processes create. An important role for scientists, educators, and decision makers is to make the integration between ecology and con sumptive uses more widely understood, as well as useful for effective management.
