Abstract

This paper describes the role of suction and related geophysical environmental conditions in the relationships between birds, sediments and benthos. We performed integrated sets of field observations/surveys and analyses at Roberts Bank and Sidney Bay in Canada and the Banzu flat in Japan. The results indicate that for a wide range of sediment types from fine sands to clay, suction is a performance index controlling the benthos diversity foraged by shorebirds. The suction dynamics was found to be closely linked to the feeding activity of Dunlins. We made clear the working mechanism in view of Ecological Geotechnics. The present finding highlights the importance of waterfront geoenvironments in the tidal flat ecosystems, and will effectively contribute to the conservation and restoration of habitats with diverse ecological activity.
