The Return of Shallow Shelf Seas as Extreme Environments: Anoxia and Macrofauna Reactions in the Northern Adriatic Sea

摘要: Anoxia is a key issue in the past and present marine ecosystems. This because no other form of disturbance so severely affects communities over such extensive areas. also only manifestation human-induced that was an important factor ancient systems. While microorganisms may rule Earth, it fundamentally macrofauna defines ecosystems provides ecosystem services on which we rely. Recurrent or intermittent hypoxia anoxia represent least consistent therefore most extreme habitat conditions for benthic communities. The unpredictable rapid onset anoxia-related mortalities has hampered our ability to document understand reactions organisms. One approach experimentally recreate, small-scale, situ. We have designed deployed experimental generating unit (EAGU), equipped with time-lapse camera sensor arrays, analyze behaviors mortality sequences Northern Adriatic (Mediterranean Sea), model eutrophication-related low dissolved oxygen events. yields information helps evaluate condition status communities, including
