In Ravenna, Autonomous Reef Monitoring Structures (ARMS) are deployed in both a harbour and touristic marina for 3 months (May-July) each year since 2021. In Venice, ARMS are deployed for one year at a long-term monitoring site. The approach combines ARMS with integrative taxonomic methods, including DNA metabarcoding (COI and 18S), photo identification of sessile fauna, and morphological identification of macrofauna. Each site deployed three replicate ARMS units annually. The objective is to track long-term ecological changes in benthic communities and detect non-native species in urban marine environments.
