Abstract

Biological invasions and chemical pollution are increasingly recognized key problems for the conservation of biological diversity. To plan species risk assessment, taxonomic species and mode of settlement and the role of temporal-seasonal factors of the fouling have been examined in the harbour of Naples (Italy). Each sample was subjected to systematic determination after fixing and microscopic observation and/or barcoding for biosecurity management of biological pollution. Our data, obtained monthly from artificial panels of Conatex immersed at different depths (from the surface up to three meters deep) showed up to now a total of 17 native species: two algal and fifteen invertebrate species, with Tunicates and Bryozoans more abundant. On the panels resulted that the specific biodiversity is not influenced by seasonality and depths; the settled biomasses is influenced by depth; a climax facies, is represented mainly by Mytilus galloprovincialis, after twelve months. Genomic DNA, using mobility shift and tunel assay, and metals detection were evaluated in gonads and/ or gametes showing fragmentation and apoptosis when arsenic, aluminum and iron increases. More information like diversity, dominance and similarity index processed with cluster analysis and statistical approach could be, in the next future, very useful for biodiversity monitoring security using the benthic communities as an early warning of biological and chemical pollution damage.
