Short CV
Born in Messina in 1976, she graduated in Natural Sciences in 1999 and obtained a Ph.D. in Environmental Sciences: Marine Environment and Resources in 2004. Her doctoral research focused on the seasonal variability of macrozoobenthic communities associated with the invasive alga Caulerpa taxifolia in the Strait of Messina.
During her academic career, she carried out laboratory activities at the Benthos Laboratory of the Ecology and Taxonomy of Benthos and Plankton Section, as well as at the laboratories of the T.A.R.G.E.T. Section (Environmental Protection – Resources and Land Management) at the University of Messina.
Since 2019, she has been employed at the Stazione Zoologica Anton Dohrn (SZN), where she currently holds the position of CTER (Technical Research Collaborator), Level VI. Her professional activity focuses on the study of benthic communities, with particular attention to polychaete fauna (both benthic and pelagic), applying classical taxonomic methods and molecular techniques, including DNA barcoding.
She actively collaborates with the Marine Organisms Taxonomy (MOTax) Service of the Stazione Zoologica Anton Dohrn in Naples and is included in the Marine Strategy Experts Short List of CoNISMa (National Interuniversity Consortium for Marine Sciences). She has participated in numerous research projects and has long been responsible for the analysis of benthic samples within the Ischiagas environmental monitoring programme.
Research Interests
My research support activity primarily focuses on the study of biodiversity variation in soft-bottom benthic communities, with particular emphasis on polychaete fauna, using an integrated methodological approach that combines both classical and molecular techniques.
Benthic communities—composed largely of sedentary organisms with relatively long life cycles—represent true biological archives, as they are capable of recording environmental alterations over medium- and long-term temporal scales. They function as decomposers and recyclers of organic matter, thereby contributing to the reduction of eutrophication; they bioturbate sediments, improving seabed oxygenation; they constitute a food source for numerous fish species; and they contribute to mitigating ocean acidification through nutrient uptake and COâ‚‚ absorption.
In marine habitats, polychaetes are among the most represented groups in terms of both abundance and diversity. Owing to several distinctive biological and ecological traits, they are frequently used as bioindicators in environmental quality assessments. They provide crucial information on the health and integrity of marine ecosystems and respond rapidly to environmental stressors—such as pH fluctuations and contamination—through changes in community structure, mortality rates, or shifts in functional traits.
Taxonomic and ecological studies make it possible both to define their trophic and functional role within the ecosystem and to identify indicator species associated with specific environmental conditions.
