EXPLORING THE PATTERN OF SEASONAL DYNAMIC DIVERSITY OF SARDINIAN SANDY SHORES MICROBIOMES

Sandy beaches have an important ecological role as transition zones between land and sea, but to date have poorly been considered for their microbial communities. Here, we report results from an analysis of bacterial communities (microbiomes) carried out with a cultivation-indepedent technique, Terminal-Restriction Fragment Length Polymorphism (T-RFLP), in sandy beaches of Marine Protected Areas of Sardinia. Data obtained showed that sandy beaches are hosting a considerable bacteria diversity, which is influenced by seasonal changes. In particular, an increase of diversity in spring compared to autumn was detected, as well as the presence of several taxa of marine origin. Further analyses will be necessary to decipher the taxa most affected in relation to the seasonal change and define the functional activities carried out by sandy beaches microbiomes
