SPATIAL DISTRIBUTION OF DENDROPOMA CRISTATUM (MOLLUSCA, GASTROPODA) ADULT BIOMASS ON A VERMETID REEF
A spatial characterization of Dendropoma cristatum biomass was carried out on a Vermetid reef in north-western Sicily. Biomass distribution of adult specimens is not homogenous in the different areas of the reef, with an increasing trend from the inner edge to the outer edge, while the central pool supports intermediate values of vermetid biomass. Considering the entire reef area, the cuvette has the highest Dendropoma biomasses of the bioconstruction, even if the highest surface-biomass ratio is found in the outer edege.
COASTAL ACCESSIBILITY AS VULNERABILITY FACTOR FOR PATELLA ULYSSIPONENSIS GMELIN, 1791 IN A MEDITERRANEAN MPA
Average density of Patella ulyssiponensis Gmelin, 1791 was correlated with costal accessibility and tourists’ density. The results highlighted that the accessibility could have a greater weight than the MPA regulation, in absence of patrolling, on the vulnerability of this sensitive species.
