Abstract

The epifaunal community of the kelp, Ecklonia radiata (C. Agardh) J. Agardh, was investigated at Portsea, Australia. The per cent cover of epifauna on the primary blade of Ecklonia was significantly greater on plants from the inner and outer pilings than on those from low on the pilings, under the pier and from an adjacent reef. Species diversity, but not the per cent cover of epifauna, was significantly greater on crinkled than on smooth plants. Various factors of disturbance were measured, including lashing by other plants, which increased with the density of plants. Other abrasive forces were found to increase closer to the bottom, as did the density of gastropods on the fronds. For each ..
