Research interests

In a broad sense, my field is evolutionary ecology of aquatic micro-organisms, in both freshwater and marine environments. My main interest is in biological interactions within and between species (e.g., from genetic recombination to trophic relationships). In my research, I pursue an integrative approach including molecular, physiology, population biology and modeling studies in order to unveil mechanisms and pathways promoting biological organization in plankton species' populations and communities. As relating to my present activity, in the frame of the Italian Project RITMARE (www.ritmare.it), I am developing conceptual and numerical models to study plankton dynamics in marine coastal regions. For instance, I am applying an end-to-end ecosystem approach to study plankton community ecology, from bacteria to carnivorous animals, with special emphasis on stability, plasticity and resilience of food-webs in face of global change. In this exercise, I am using the LTER (Long Term Ecological Research) time-series MareChiara (Gulf of Naples) as a reference database. Based on information coming from the latter and the literature, I recently implemented a carbon-based food-web model using the software Ecopath, which reproduces matter fluxes in the whole planktonic food-web of the Gulf of Naples. In general, I am interested in "network thinking in ecology and evolution", being a web the best way to investigate the effects of biological interactions on communities within a single and integrated context. Finally, I am also involved in science communication actions, such as those promoted by the network of research LTER-Italy
