Wilkinson MT, Richards PJ, Humphreys GS. 2009. Breaking ground: Pedological, geological, and ecological implications of soil bioturbation. Earth-Science Reviews 97: 257-272.
These authors describe the process of bioturbation in soils, and the roles of various major groups of organisms, especially animals, responsible for bioturbation. Through mixing and surface-mounding, bioturbation sorts, buries, and transports soil and soil components such as organic matter. Bioturbation also interacts with abiotic processes, particularly those involving surface water inputs and movements, to create net effects on soil movement and sorting.
There is a great deal of detail in the description of various sub-processes and rates, as well as some urging for more detailed studies of these phenomena. This paper is required reading for the course SLSC 834, in August 2010.
