Research interests

DNA barcoding links each species to a unique DNA sequence, whereas environmental DNA (eDNA) or metabarcoding uses this linkage to identify taxa from natural communities. Molecular data from eDNA generated using Next-Generation Sequencing (NGS) are increasing and changing our way to monitor natural communities at spatial and temporal scales, offering the possibility to integrate them in resources conservation and management plans. However, standardised protocols to identify, delimiting and quantifying species from molecular NGS data are still being developed. NGS data collected at the long term station LTER-MC, in the Gulf of Naples, provide a strong framework to establish both the potential applications and the limitations of this approach. With this aim, I’m currently analysing 18S and 16S amplicons obtained on an Illumina platform from eDNA collected over three consecutive years. Using bioinformatics tools on these data, I investigate community diversity at several taxonomic levels, from the whole protist assemblage to specific groups (e.g. Bacillariophyta and Dinophyta) or key genera. I am also analysing of amplicons from the European project BioMarKs to assess biodiversity differences among several coastal ecosystems. My broad interest is molecular evolution, with emphasis on processes which lead to selection, diversification and taxonomic complexity, and application of methods for rapid and objective characterization of species diversity.
