Research Interest
Gelatinous zooplankton (pelagic cnidarians, ctenophores and pelagic tunicates) are considered a nuisance because they interfere with fisheries, touristic and industrial activities along the coast. Indeed they play a key yet not well defined role in marine ecosystems. Gelatinous zooplankton prey upon plankton and are in turn ingested by fish, sea turtles, sea mammals and birds, therefore they are located at intermediate trophic levels of the food web. Past research focused on the definition of their diet, while their interactions with potential competitors - planktivorous fish prey upon plankton alike - and predators - gelatinous tissues are difficult to detect within stomach contents - are still little known. For a better management of the ecosystem, the role of gelatinous zooplankton needs to be well defined.
Using the ability to breed gelatinous zooplankton in captivity and the expertise in applying stable isotope analysis developed during the PhD in the US, I worked on different aspects of their biology and ecology (life cycles, parasitism, taxonomy, fluid dynamics, prey capture, feeding patterns, competition with forage fish and association with forage fish juvenile stages). Overall my results confirmed that the role of gelatinous zooplankton in marine ecosystems is complex.
By using the skills already in my possess and developing new ones, I will work on the definition of the ecological role of gelatinous zooplankton in the gulf of Napoli, where the data available are scarce, fragmentary and out-of-date, eventually in coordination with national and international research programs.
