Available in PDF, EPUB and Kindle. Book excerpt: change is simply described by the rate of income and rate of loss. Our home's energy budget, our firm's inventory, our nation's debt, and humanity's numbers all have accounts that change at rates that are equal to the inputs minus the outputs. Jenny's "system view" of the soil was carried into the fertile fields of Midwestern American prairies from the laboratories of Switzerland in the late 1920s. Jenny's rate equations provided the other paradigm or world view that, I recall, brought us to the threshold of systems ecology as it later evolved in the second half of the twentieth century. As if world renown in the specialties of pedology and soil chemistry were not enough for one lifetime, excerpts below remind us that Hans Jenny has also been a perceptive outdoor field ecologist since his early Alpine expeditions with Braun Blanquet in the mid 1920s. Jenny's ecosystem studies in the pygmy forest, a further classic example of a soil-plant system "run down" over hundreds of thousands of years since its origin, continue to occupy some of the vigorous retirement time near his farm in Mendocino County. But each specific, quantitative case study, and each research area conserved (with additional hard work) for further study by future generations, fits into Jenny's coherent world view. It is that view, and its legacies of discovery and of tangible landscape preserves, which we are privileged to share with their originator in this volume.

Book excerpt: Stressing the significance of vegetation in geomorphology, an often ignored area, it presents the results of the 1988 British Geomorphological Research Group conference, which brought together work in progress or recently completed on plant processes and geomorphological interactions. According to the editor, these results, while encouraging, are only a start, indicating a preponderance of past work dealing with vegetation simply as an extrinsic variable. The text focuses on vegetation as a highly dynamic and vital component that affects virtually all processes and therefore all geomorphological histories. By raising these and other issues, it indicates a variety of avenues for future investigation.
