The long-term effects of limpets on a marine biofouling community were studied. Each of six 20 cm2 shipping-steel panels was artificially colonized by 15 Patella caerulea limpets transplanted from intertidal rocks. Six other panels served as controls. The panels were hung at 1 m and 5·5 m depth from a pier in an Israeli port, and fouling was allowed to occur for 8 months. During winter, when fouling recruitment was low, the limpets reduced the 84%-90% cover of biofouling to 1 %-3%, and barnacle density from 2·6-3·8 to 0·7-0·8 individuals·cm-2. With the commencement of the spring surge of fouling recruitment, the controlling effects of the limpets steadily declined, but they continued to check the development of the high-mass bryozoan cover. The decline was due to a feed-back loop; heavy settlement of barnacles brought about an initial reduction in control that resulted in increased barnacle sizes and density. This also induced accelerated mortality among limpets, bringing about a further increase in barnacle density. |
