Sampling comments: "six sites (distant 90 m each other) were established over the greatest linear dimension referred to south-north direction of the island, and were monthly sampled from January to December 2001. At each site, three macrofauna sub-samples were taken using a corer tube (0.008 m² area, 20 cm depth). Biological samples were sieved in situ through a 0.3 mm mesh size"
