This issue's cover: The Bw horizon of a Fluvaquentic Dystrudepts is refuge for a native species of earthworm (Diplocardia longiseta Murchie, 1963) when soil moisture declines in summer. Earthworms migrate downward in this East Texas forest soil and eventually enter a state of quiescence in a tight irregular coiled ball. During this migration, earthworms incorporate organic matter into lower soil horizons by cast production and influence soil structure by macropore and aggregate formation. The image relates to the paper Earthworm Populations in Upland Mixed Pine-Hardwood and Bottomland Hardwood Forest Soils in East Texas presented at the SSSA 2004 Annual Meeting by George Damoff (gdamoff@sfasu.edu) and Kenneth W. Farrish. The paper was presented to Division S-7 Forest & Range Soils. (Photo by George A. Damoff and Kenneth W. Farrish, Arthur Temple College of Forestry and Agriculture, Stephen F.
