Reappraising the Geomorphology - Ecology Link – Themed Topic, October 2009

Edited by Stephen E. Darby

There has been a progressive recognition that the interface between the biosphere and earth surface processes matters. This themed issue highlights a personal selection of 18 recent (2007-2009) contributions to Earth Surface Processes and Landforms which show our state of the art understanding of how the biosphere interacts with the physical and chemical processes of sediment transfer/transformation. It shows that not only does sediment response depend sensitively on biospheric processes but that the biosphere itself is strongly influenced by geomorphology.
