Associations of forest-type with morphology of Ecklonia radiata and abundance of understorey algae
This study tested for ecological differences between monospecific and mixed-species stands of subtidal canopy-forming algae. At three sites on the northern shore of St Francis Island, we determined the proportional cover of four configurations of canopy-forming algae: (i) monospecific stands of Eckl...
