Large wood is an important restoration tool in aquatic ecosystems as it has a variety of geomorphological and ecological benefits. We have limited knowledge regarding the role of large wood in large rivers as most research focuses on streams and small rivers. This research aims to understand the characteristics and dynamics of large wood in Pool 8 of the Upper Mississippi River while examining environmental conditions that influence periphyton accrual and macroinvertebrate colonization on wood. We surveyed naturally occurring large wood along shorelines of reconstructed islands between September and July and deployed wood substrate samplers across varying flow habitats in June that were sampled biweekly until September. The positive net change in wood abundance (+3.2 pieces) and shift in wood characteristics (unattached, dry, and bare without bark) along this flow gradient suggests that flow dynamic is a primary factor influencing wood abundance and mobilization. Arthropod dry mass (1.1 mg/cm2), abundance (73 individuals), and richness (3 order taxa) were greatest in higher flow habitats where additional habitat substrate was limited, whereas periphyton accrual was similar across flows. The information we provide on use of wood substrates by periphyton and macroinvertebrates across habitat conditions may be further used to link higher trophic level interactions with large wood. Overall, this study supports that large wood is an effective tool in restoration efforts aimed at improving habitat heterogeneity by increasing available substrate.

The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.

"This is a very readable book in which the ecological concepts are carefully explained and the glossary of key terms will be a welcome inclusion for those getting to grips with ecology. The book will therefore appeal to a wide readership of aquatic ecologists and foresters, both professional and amateur alike". Scottish Forestry Royal Scottish Forestry Society"...the book makes a very significant contribution to our growing awareness of the ecological importance of driftwood. This contribution is founded on two particular aspects of the book: the writing style, which is clear and directed very much at the general reader; and the scope of the book, which is very broad and, to my knowledge, goes far beyond other reviews of the topic". Angela Gurnell School of Geography, University of Birmingham British Journal of Forestry"This is not a review article containing a current review of all works on wood in aquatic ecosystems. Instead, it is a comprehensive treatment of the general role of wood". J.L. Tank and J.R. Webster Journal of the North American Benthological SocietyFrom the Forest to the Sea: The Ecology of Wood in Streams, Rivers, Estuaries and Oceans is a fascinating scientific work that discusses the role wood plays in very complex and diverse aquatic ecosystems.
