Abstract

The paper describes an interspecific comparison of burrowing capabilities of benthic fauna in tidal flats. By utilizing our new approach in Ecological Geotehcnics, we simulated and varied surface shear strengths of bed materials, to which we observed the responses of six species of invertebrates that belong to Arthropoda, Mollusca, and Annelida. The results demonstrate that for each of the burrowing activities there exist optimal, transitional and critical surface shear strengths, which are found to differ considerably between species, body sizes and weights. We have constructed a chart by which to examine such difference in the burrowing capabilities in an integrated manner in light of the associated geophysical environments in the field. This chart provides fresh important insights into natural selection of habitats of benthic fauna in tidal flats.
