| Resumo: |
Observing that wave induced sweeping of the fronds of plants at the edges of kelp patches results in a relatively barren interface between kelp plants and the surrounding animal patches led to the assumption that: a) kelp sweeping could provide protection for macrophytes from grazers; and b) that it could be a mechanism allowing kelp patch expansion. The validity of the hypothesis was supported by quantitative observations on the sweeping capabilities of individual kelp plants and by characteristic species/biomass distributions within the kelp sweeping zone, the kelp patches and the adjacent animal patches. In addition, experimental clearing of the primary substrate within the various areas showed that free space will be completely occupied within 50 days unless kelp sweeping stops the faunal progression. A model describing the mechanisms that bring about successional changes at the edge of a kelp patch and leading to its expansion is proposed.
