Book Description
This collection represents a unique set of essays on the role of theory in shaping the practice of medicine across disciplinary boundaries. In the context of this volume, "theory” relates to the conceptual models, frameworks, knowledge representations, metaphors and analogies that inform the problem-solving efforts of practitioners seeking to develop novel dialogues both within and across disciplinary boundaries. Contributors to this volume include computational scientists, chemists, medical researchers, biologists and philosophers, all drawing on personal experience in their respective fields to produce a genuinely interdisciplinary range of perspectives on the common theme of theory in medical thinking and multidisciplinary research practice. * Selected and edited papers from the 10th North American Forest Soils Conference held in Saulte Ste. Marie, Ontario, Canada, July 20-24, 2003 * A unique spin-off from Elsevier's highly regarded journal, Forest Ecology and Management * An estimated 400 pages of the latest findings in forest soil ecology from the most prominent researchers in the field

Book Description
Stream bank stability is gaining increasing attention in part because stream bank erosion can contribute as much as 80% of suspended sediment to streams, particularly in urbanizing watersheds. Stream bank erosion study sites were located in a lower reach of the Hinkson Creek Watershed located in Boone County, Missouri, USA. Streambank erosion and deposition rates were quantified using the erosion pin method comparing a remnant Bottomland Hardwood Forest (BHF) streambank to an Agricultural (Ag) streambank (922 m apart). Ten erosion pin plots (n = 342 pins) were installed that spanned the range of bank geometric and vegetation cover variability. Results indicated that during a drier (762 mm) than average (10yr avg=1077 mm) rainfall year 15.6 and 177.7 tonnes of soil erosion occurred on the right stream bank alone of the BHF and Ag sites respectively (Water Year 2011). Average erosion depth of the BHF and Ag was 18 and 112 mm/yr respectively. The greatest average depth of erosion occurred during the winter season (44.7 mm), followed by summer (13.1 mm) and spring (6.3 mm), fall had the lowest average erosion rate (1.1 mm). The stream bank erosion contributed approximately 67% of channel suspended sediment loading over WY 2011.Results hold important implications for land-use and land managers wishing to improve land-use practices, water quality and natural resource sustainability in dynamic urbanizing watersheds.

Book Description
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.
