Microorganisms play a crucial role in all the environments they inhabit, including coastal areas. These ecosystems are facing increasing pressures due to climate change, rising sea levels, and mitigation measures. One such measure in the Venice lagoon is the MOSE system, a large-scale infrastructure designed to protect the city of Venice from tidal events by regulating water inflow from the sea. To understand the ecological co...

The MOSE (Experimental Electromechanical Module), consisting of rows of mobile gates can temporarily isolate the Venice lagoon from the Adriatic Sea during extreme high tides. To investigate how the lagoon ecosystem is affected by a prolonged segregation from the oxygenating seawater, we performed two enclosure experiments in July 2019 (48h) and October 2020 (28h) by artificially secluding small portions of the organic-enriche...
