burrow photographed against the backdrop
of a monolith of the soil from which it was obtained. Approximate length 1 m.
Example of a fiberglass replica of an
L. terrestris
of water coming from individual earthworm burrows is monitored, and studies in which the overall
effect of earthworm presence on infiltration rate of the bulk soil is investigated. These studies have
shown that burrows made by anecic and endogeic species of earthworms can effectively conduct
water (Zachmann et al. 1987; Joschko et al. 1992; Trojan and Linden 1992; Shipitalo et al. 2000).
