TEDITORS' NoTE.-The authors wish to note that this synthesis is based on the long-term research efforts of many South African and international researchers, too numerous to name, who have worked and are working on and around the Prince Edward Islands and have made considerable contributions. The South African De- partment of Environmental Affairs and Tourism (DEA&T) and several South Afri- can universities provided logistic and financial support for research undertaken on the islands. The authors gratefully acknowledge many fruitful years of cooperation with the Directorate Antarctica and Islands of the DEA&T. The authors wish to especially thank William Froneman, who inspired the title of this synthesis.

3. Allochthonous input-input of productivity from other systems, which usu- ally increases resource availability in a local system. This is an opposite of an autoch- thonous input, which is a result of a local productivity enhancement. 4. E.

The "island mass effect" is enhancement of biological productivity and biomass around the island systems. This may include increases in chlorophyll and plankton concentrations in surrounding waters, retention of larval and juvenile stages of fish, recirculation and increases in larval abundance, eddies trapped and created on the lee side of the island systems. 15.
