Experimental manipulations of the density of Cymbula granatina on rocky shore community

Densities of a commonly-harvested intertidal limpet Cymbula granatina were manipulated at two sites within a no-take marine protected area on the west coast of the Cape Peninsula in South Africa, using four treatment levels ranging from zero to maximum natural densities, together with control plots, to evaluate the effects of different harvesting intensities on rocky shore community composition. Following removal or thinning of C. granatina, community composition changed: cover of corticated...
