Research Abstract

Kelp beds can be maintained locally in sea urchin-dominated barrens due to the restriction on urchin feeding by wave action which increases with decreasing depth. Long-term velocity determination revealed that the probability for the wave-induced orbital velocity near the lower edge of persistent kelp beds lower than the upper limit for urchin feeding was not zero but approximately 20%. A laboratory flow tank experiment and field study showed that the cover of microalgae or crustose algae in and around kelp beds reduced urchins attachment strength and thus the upper velocity limit for their invasion, facilitating the maintenance of the beds.
